VS-80PF80 Equivalent & Substitute Parts
Part Overview
The VS-80PF80 is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 800 V DC reverse voltage and 80 A average rectified current. The device is housed in a DO-203AB (DO-5) stud mount package, suitable for chassis-mounted applications requiring high current rectification at elevated voltage levels. The part maintains Active product status and is RoHS3 compliant. Substitute parts are identified when inventory constraints, lead time requirements, or supply chain disruptions necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation
Substitution of the VS-80PF80 is determined by strict equivalence across the following critical parameters:
- Voltage Rating: 800 V DC reverse voltage (Vr) maximum
- Current Rating: 80 A average rectified current (Io)
- Forward Voltage: 1.4 V maximum at 220 A forward current (Vf)
- Recovery Characteristics: Standard recovery speed >500 ns at >200 mA
- Package Type: DO-203AB (DO-5) stud mount configuration
- Temperature Range: -55°C to 180°C junction operating temperature
- Compliance: RoHS3 compliant, REACH unaffected
The substitute part VS-80PF80W meets all specified electrical parameters and mechanical requirements. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical base product designation (80PF80). Substitution is valid only when all parameters listed above are matched.

Engineering Selection Recommendations
Both VS-80PF80 and VS-80PF80W are Active products manufactured by Vishay General Semiconductor - Diodes Division and maintain full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and supply chain considerations rather than electrical or mechanical differentiation.
VS-80PF80: Primary selection when available. Current inventory: 1245 pieces.
VS-80PF80W: Direct substitute when primary part is unavailable. Current inventory: 766 pieces. Identical electrical performance and mechanical compatibility.
Both parts are suitable for high-current rectification applications requiring 800 V blocking voltage and 80 A average rectified current in stud-mounted chassis configurations. No design modifications are required when substituting between these parts.
Frequently Asked Questions (FAQ)
Q: Can VS-80PF80W be used as a direct replacement for VS-80PF80?
A: Yes. Both parts are electrically and mechanically identical. They share the same voltage rating (800 V), current rating (80 A), forward voltage characteristics (1.4 V @ 220 A), recovery speed, package type (DO-203AB stud mount), and operating temperature range (-55°C to 180°C). No circuit modifications are required.
Q: Are there any differences in the mounting configuration between these parts?
A: Both parts use stud mount configuration in the DO-203AB (DO-5) package. The VS-80PF80 is specified as "Chassis, Stud Mount" while VS-80PF80W is specified as "Stud Mount." This designation difference does not affect mechanical compatibility or electrical performance.
Q: What compliance certifications apply to both parts?
A: Both VS-80PF80 and VS-80PF80W are RoHS3 compliant and REACH unaffected. Both carry ECCN classification EAR99 and HTSUS code 8541.10.0080.
Q: Is there a performance difference in recovery speed between the two parts?
A: No. Both parts exhibit identical standard recovery characteristics: >500 ns at >200 mA (Io).
Q: Can these parts be used interchangeably in existing designs?
A: Yes. The parts are fully interchangeable. No PCB layout modifications, thermal management adjustments, or circuit design changes are necessary when substituting between VS-80PF80 and VS-80PF80W.
Q: What is the moisture sensitivity level for these parts?
A: Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
