VS-80APF06PBF Equivalent & Substitute Parts

Part Overview

The VS-80APF06PBF is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 600 V DC reverse voltage and 80 A average rectified current in a through-hole TO-247AC package. This part is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design support and procurement continuity. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating packaging and availability constraints.

Substitute Part Grouping Explanation

Substitute parts for the VS-80APF06PBF are classified based on electrical parameter compatibility and product availability status. The primary substitution criterion is maintenance of the 600 V reverse voltage rating and 80 A average rectified current specification. Parts are grouped as follows:

Direct Equivalent (Same Electrical Specifications): VS-80APF06-M3 maintains identical electrical parameters (600 V, 80 A, 1.25 V forward voltage, 190 ns recovery time) and differs only in packaging format (Tube versus unspecified original packaging). This part is classified as Active and represents the primary substitute for the obsolete VS-80APF06PBF.

Manufacturer-Recommended Substitute (Reduced Current Rating): STTH31AC06SWL is an STMicroelectronics alternative with identical 600 V reverse voltage rating but reduced to 30 A average rectified current. This part is suitable only for applications where the 80 A current requirement can be reduced or where parallel configurations are implemented. The part exhibits improved reverse recovery time (65 ns versus 190 ns) and extended operating temperature range (-40 to 175°C versus -40 to 150°C).

Substitution logic is strictly limited to the following parameters: reverse voltage rating (600 V), package type (TO-247-3 or TO-247), mounting method (through-hole), and compliance certifications (ROHS3, REACH Unaffected).

Engineering Selection Recommendations

For Direct Replacement: VS-80APF06-M3 is the primary substitute for VS-80APF06PBF. Both parts maintain identical electrical specifications (600 V, 80 A, 1.25 V forward voltage, 190 ns recovery time) and are housed in the TO-247-3 package. VS-80APF06-M3 is classified as Active with higher inventory availability (1090 pcs in stock versus 741 pcs for the obsolete main part). Both parts are ROHS3 Compliant and REACH Unaffected, ensuring regulatory compliance continuity.

For Current-Reduced Applications: STTH31AC06SWL is suitable only when the application circuit can operate at 30 A average rectified current instead of 80 A. This part offers improved performance characteristics including faster reverse recovery time (65 ns) and extended junction temperature range (-40 to 175°C). The higher forward voltage (2 V @ 30 A) and lower reverse leakage current (10 µA @ 600 V) must be evaluated against circuit thermal and efficiency requirements. STTH31AC06SWL is ROHS3 Compliant and REACH Unaffected.

Selection must be based on circuit current requirements and thermal design constraints. No substitution is valid if the application requires sustained 80 A operation.

Frequently Asked Questions (FAQ)

Q: Can VS-80APF06-M3 be used as a direct replacement for VS-80APF06PBF?

A: Yes. VS-80APF06-M3 is a direct electrical equivalent with identical voltage (600 V), current (80 A), forward voltage (1.25 V @ 80 A), and recovery time (190 ns) specifications. Both use the TO-247-3 package and through-hole mounting. The only difference is packaging format (Tube). VS-80APF06-M3 is Active status with higher inventory availability.

Q: What are the limitations of STTH31AC06SWL as a substitute?

A: STTH31AC06SWL has a reduced average rectified current rating of 30 A compared to the 80 A requirement of VS-80APF06PBF. This part is suitable only for applications where the circuit can operate at 30 A or lower. The part cannot be used in designs requiring sustained 80 A operation. Forward voltage is higher (2 V @ 30 A), which increases power dissipation.

Q: Are all substitute parts compatible with the same PCB layout?

A: Yes. All three parts (VS-80APF06PBF, VS-80APF06-M3, and STTH31AC06SWL) use the TO-247-3 package with identical pin configuration and through-hole mounting. PCB layout and thermal management design remain unchanged.

Q: Do substitute parts maintain regulatory compliance?

A: Yes. Both VS-80APF06-M3 and STTH31AC06SWL are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the main part VS-80APF06PBF.

Q: What is the primary reason for substitution?

A: VS-80APF06PBF is classified as Obsolete. VS-80APF06-M3 is the recommended substitute as it maintains all electrical specifications while being in Active status with confirmed inventory availability.
