W06G Bridge Rectifier Single Phase 600V 1.5A Equivalent & Substitute Parts
Part Overview
The W06G is a single-phase bridge rectifier manufactured by Diodes Incorporated, rated for 600V peak reverse voltage and 1.5A average rectified current in a through-hole WOG package. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. Substitute parts must maintain electrical performance within the specified parameter ranges while meeting the same mechanical and environmental requirements.

Substitute Part Grouping Explanation
Substitution of the W06G is determined by strict equivalence across the following critical parameters:
- Diode type and technology classification (Single Phase, Standard)
- Voltage rating: 600V peak reverse voltage minimum
- Current rating: 1.5A average rectified current minimum
- Forward voltage characteristics within specified limits
- Reverse leakage current at rated voltage
- Through-hole mounting in 4-Circular WOG package
- Operating temperature range compatibility
- RoHS3 compliance and regulatory alignment
The W06G-E4/51, manufactured by Vishay General Semiconductor - Diodes Division, meets these substitution criteria. Both parts share identical electrical ratings, package configuration, and compliance certifications, establishing direct functional equivalence.

Engineering Selection Recommendations
The W06G-E4/51 is a direct substitute for the obsolete W06G. Both components are ROHS3 compliant and share identical electrical specifications, package geometry, and mounting configuration. The W06G-E4/51 maintains active product status with confirmed inventory availability, eliminating supply chain risk associated with the obsolete W06G.
The operating temperature range of the W06G-E4/51 (-55°C to 150°C) is narrower than the W06G (-65°C to 150°C) at the lower bound. Applications requiring operation below -55°C must evaluate this difference against actual system requirements. For standard industrial and consumer applications operating within -55°C to 150°C, the W06G-E4/51 provides full functional equivalence.
Frequently Asked Questions (FAQ)
Q: Can the W06G-E4/51 be used as a direct replacement for the W06G?
A: Yes. Both parts are single-phase bridge rectifiers with identical 600V/1.5A ratings, forward voltage characteristics, reverse leakage specifications, and 4-Circular WOG package configuration. Electrical and mechanical compatibility is established.
Q: What is the difference in operating temperature range?
A: The W06G operates from -65°C to 150°C, while the W06G-E4/51 operates from -55°C to 150°C. The lower temperature limit differs by 10°C. Applications requiring operation below -55°C must confirm compatibility with actual system thermal requirements.
Q: Are both parts RoHS compliant?
A: Yes. Both the W06G and W06G-E4/51 are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components.
Q: What is the significance of the WOG package designation?
A: WOG is a standardized through-hole package for single-phase bridge rectifiers. Both parts use this identical package configuration, ensuring mechanical and electrical compatibility in PCB layouts and circuit designs.
Q: Why is the W06G listed as obsolete?
A: The W06G has been discontinued by Diodes Incorporated. The W06G-E4/51 from Vishay provides equivalent functionality with active product status and ongoing supply availability.
Q: Are there differences in forward voltage specifications?
A: The W06G specifies 1 V maximum forward voltage at 1.5 A, while the W06G-E4/51 specifies 1 V maximum at 1 A. Both meet the 1 V specification at their respective rated currents. For applications operating at 1.5 A, verify that the Vishay part's forward voltage performance meets circuit requirements.
