W005M Bridge Rectifier Single Phase 50V 1.5A Equivalent & Substitute Parts

Part Overview

The W005M is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 50 V peak reverse voltage and 1.5 A average rectified current. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support, maintenance, and new production applications. The W005M features a through-hole WOM package configuration with standard rectifier technology and operates across a temperature range of -65°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the W005M is determined by strict equivalence across the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - Peak Reverse (Max): 50 V (exact match required)
• Diode Type: Single Phase (exact match required)
• Mounting Type: Through Hole (exact match required)
• Technology: Standard (exact match required)
• Current - Average Rectified (Io): 1.5 A or higher (equal or greater capacity acceptable)
• Package / Case: 4-Circular configuration (mechanical compatibility)

Secondary Compatibility Factors:

• Voltage - Forward (Vf) (Max) @ If: Must not exceed application requirements
• Current - Reverse Leakage @ Vr: Lower values indicate improved performance
• Operating Temperature Range: Must encompass application requirements or be acceptable for the specific use case

Two substitute parts meet these criteria: the 2W005G-E4/51 (2 A rated) and the W005G-E4/51 (1.5 A rated), both manufactured by Vishay General Semiconductor - Diodes Division. Both are active products with through-hole WOG package configurations and 50 V peak reverse voltage ratings.

Parameter Comparison

Engineering Selection Recommendations

W005G-E4/51 (Vishay General Semiconductor - Diodes Division)

The W005G-E4/51 provides direct electrical equivalence to the W005M with identical current rating (1.5 A) and forward voltage characteristics (1 V @ 1 A). This part is an active product with ROHS3 compliance and REACH unaffected status. The operating temperature range extends to 150°C, providing broader thermal coverage than the original W005M. Reverse leakage current is improved at 5 µA compared to the W005M specification of 10 µA. The 4-Circular WOG package maintains mechanical compatibility with through-hole mounting requirements. This substitute is the preferred direct replacement for applications requiring exact current rating equivalence.

2W005G-E4/51 (Vishay General Semiconductor - Diodes Division)

The 2W005G-E4/51 offers increased current capacity at 2 A average rectified current, exceeding the W005M specification of 1.5 A. This part is suitable for applications where higher current margin or future design headroom is required. Forward voltage is specified at 1.1 V @ 2 A, which is acceptable for most standard rectifier applications. Reverse leakage current is 5 µA, matching the W005G-E4/51 performance. The part is ROHS3 compliant and REACH unaffected. Operating temperature range extends to 150°C. The 4-Circular WOG package maintains through-hole mounting compatibility. This substitute is appropriate when current derating or design margin improvement is a consideration.

Both Vishay substitutes are active products with established supply availability and compliance certifications, addressing the obsolescence status of the W005M.

Frequently Asked Questions (FAQ)

Q: Can the W005G-E4/51 directly replace the W005M without circuit modification?

A: Yes. The W005G-E4/51 matches the W005M in voltage rating (50 V), current rating (1.5 A), forward voltage characteristics (1 V @ 1 A), and mounting type (through-hole). The 4-Circular package configuration is mechanically compatible. No circuit modification is required.

Q: What is the difference between the W005G-E4/51 and 2W005G-E4/51?

A: The primary difference is current rating. The W005G-E4/51 is rated for 1.5 A average rectified current, matching the W005M specification. The 2W005G-E4/51 is rated for 2 A, providing 33% additional current capacity. Both share identical voltage ratings (50 V), forward voltage characteristics at their respective current levels, and operating temperature ranges (-55°C to 150°C). Selection depends on whether exact current equivalence or increased current margin is required.

Q: Are the WOM and WOG packages mechanically interchangeable?

A: Both packages use 4-Circular through-hole configuration and are mechanically compatible for PCB mounting. The WOM (GeneSiC) and WOG (Vishay) designations indicate manufacturer-specific package variants. Physical dimensions and lead spacing are compatible for standard through-hole applications.

Q: What is the significance of the lower reverse leakage current in the Vishay substitutes?

A: The Vishay parts specify 5 µA reverse leakage at 50 V, compared to 10 µA for the W005M. Lower reverse leakage indicates reduced parasitic current flow in the reverse-biased state, which can improve circuit efficiency and reduce heat generation in applications with high reverse voltage stress. This is a performance improvement, not a compatibility issue.

Q: Do the Vishay substitutes support the full temperature range of the W005M?

A: The W005M operates from -65°C to 125°C. The Vishay substitutes operate from -55°C to 150°C. The Vishay parts do not extend to the -65°C lower limit of the W005M. For applications requiring operation below -55°C, the W005M specification cannot be fully matched. For applications within -55°C to 125°C, the Vishay substitutes are fully compatible and provide extended upper temperature capability.

Q: Are the Vishay substitutes RoHS compliant?

A: Yes. Both the W005G-E4/51 and 2W005G-E4/51 are ROHS3 compliant and REACH unaffected. The W005M compliance status is not specified in the provided data.

Q: What inventory status should be considered for production planning?

A: The W005M is obsolete with 877 pieces in stock. The W005G-E4/51 is active with 1920 pieces available. The 2W005G-E4/51 is active with 6697 pieces available. For new designs and ongoing production, the active Vishay substitutes provide established supply chains and long-term availability.
