BOJACK CL04-12 Microwave Diodes (Pack of 2)
These high voltage diodes from BOJACK are designed for microwave repair parts. They withstand 12 kV and handle up to 0.5 A, making them suitable for numerous microwave models that require a robust CL04-12 replacement. The pack of two provides ready redundancy for common repair scenarios where one diode might fail or to stock for future maintenance.
Considerations include matching the diode’s voltage rating and current with your oven’s original part. The CL04-12 series is widely used in replacement contexts, potentially reducing downtime when you need a quick fix for diode-related issues in high-voltage circuits.
W11256462 EXPHV13 High Voltage Diode
The EXPHV13 diode is presented as a microwave oven high voltage rectifier with a 12 kV rating. It lists 350 mA capability and emphasizes an isolated case with surge overload protection, which can enhance safety in repair work. This diode is often chosen for models that require a slightly different fit or mounting arrangement while still delivering reliable rectification for the high-voltage rail.
When selecting this part, verify mounting dimensions and lead connections to ensure compatibility with your oven’s HV circuit, especially if you’re upgrading from an older diode type or replacing multiple components at once.
Comimark CL04-12 5 Pieces
Comimark offers a 5-piece CL04-12 set designed for microwave diode replacements. Each diode is rated at 12 kV with a current around 0.45 A, providing a cost-effective option for technicians who perform multiple microwave repairs or require spares for ongoing service work. The bundle helps reduce per-unit cost while maintaining high voltage performance.
In practice, this pack is suitable for models that use the CL04-12 family and may help streamline repair workflows in professional settings or large households with frequent microwave issues related to high voltage diodes.
HUAREW CL04-12 Microwave Diodes
HUAREW’s CL04-12 diodes are positioned as multipurpose replacements with a 12 kV withstand rating and 0.5 A current rating. The product description notes broad applicability beyond microwaves, including high-voltage power supplies and related equipment. The pack typically contains two units, offering a straightforward upgrade path for compatible models that require robust, compact rectifiers.
Key decision factors include ensuring the exact mounting footprint and electrical connections align with your oven’s design to avoid remanufacturing nearby components or rewiring needs during installation.
HUABAN CL01-12 3-Pack Diodes
HUABAN’s CL01-12 diodes come in a three-pack, offering 12 kV withstand voltage and 0.35 A forward current. This option suits models requiring slightly lower current handling while maintaining high voltage rectification. The CL01-12 family is a common substitute for several microwave models, including those that reference T3512, T4512, and related part numbers in their service documentation.
Practical considerations include evaluating whether your device’s existing diode tolerances align with 0.35 A current and verifying compatibility with the oven’s control board and HV transformer wiring.
Buying Guide: Key Considerations For Selecting Microwave High Voltage Diodes
- Voltage rating: Most listed diodes are around 12 kV. Match the diode’s peak inverse voltage with your microwave’s HV circuit requirements to prevent arcing or failure.
- Current rating: Typical forward current ranges from 0.35 A to 0.5 A. Ensure the current rating aligns with the original part to maintain safe operation and longevity.
- Package and mounting: Check the diode’s package type, pin spacing, and mounting method. Some models use metal-ceramic casings; others are compact plastic assemblies. Incorrect mounting can cause mechanical or electrical issues.
- Lead connections and terminals: Confirm terminal sizes and types (solder lugs vs. crimped terminals). Some listings mention heat shrink protection for the female side, which can aid installation safety.
- Compatibility: Diodes are often cross-listed for several part numbers (HVM12, T3512, T4512, W10245187, etc.). Verify the exact cross-reference against your oven model and service manual.
- Quantity and packaging: Bundles (2 pcs, 3-pack, 5 pcs) offer value for technicians and home repair enthusiasts who need spares or want to replace multiple units in one service cycle.
- Material and safety: High-voltage diodes may employ metal and plastic construction. Ensure proper insulation and installation practices to prevent shock or short circuits.
- Application scope: While designed for microwave ovens, these diodes are also used in high-voltage supplies, X-ray machines, and other industrial equipment. Consider the environment and electrical noise when selecting a diode.
- Vendor reliability: Seek listings from reputable brands and confirm compatibility notes in product descriptions to minimize returns and ensure proper fit.
- Installation context: If you are not replacing related high-voltage components (like HV capacitors or transformers), you may risk repeated failures. In some cases, inspecting surrounding components is prudent.
When choosing among these options, balance the diode’s voltage and current specs with your oven’s original design, mounting method, and service history. For basic repairs or first-time replacements, selecting a well-reviewed, commonly used CL04-12 variant with a compatible footprint often yields dependable performance and easier installation.
