VS-85HFL60S02

Single Diodes Overview

The VS-85HFL60S02 is a fast recovery rectifier diode from the Vishay VS-85HFL series, rated for an average forward current of 85 A and a maximum repetitive peak reverse voltage of 600 V. It utilizes a DO-5 (DO-203AB) stud mount package with a cathode-to-stud configuration. The device features a typical reverse recovery time of 50 ns at 25 °C under specified test conditions. Maximum ratings include a junction temperature range of -40 °C to +125 °C, a non-repetitive peak surge current of 1151 A at 60 Hz, and a maximum forward voltage drop of 1.75 V.

Single Diodes Procurement Notes

Verify the specific suffix S02 indicates the standard stud base thread size (1/4" 28UNF-2A) rather than metric variants. Confirm the absence of the 'R' designation ensures the correct cathode-to-stud polarity for the intended circuit topology. Cross-reference the thermal resistance values against the actual heatsink interface conditions to ensure compliance with maximum junction temperature limits during operation.

Single Diodes Selection Notes

Select this component when high-speed switching performance is required alongside high current handling capabilities. The 600 V rating provides adequate margin for standard industrial AC line voltages. Ensure the mounting surface meets the smoothness and flatness requirements to maintain the specified thermal resistance. Consider the 1.75 V forward voltage drop for power loss calculations in continuous conduction modes.

Single Diodes Part Context

This part belongs to the VS-85HFL series of fast recovery diodes manufactured by Vishay Semiconductors. The series includes variants with different voltage ratings ranging from 100 V to 1000 V and shares common mechanical dimensions within the DO-5 package family. The '60' in the model number specifically denotes the 600 V reverse voltage rating, distinguishing it from other members of the 85 Ampere current class.

Single Diodes FAQ

What is the difference between the S02 and S05 suffixes?

The S02 suffix indicates a standard 1/4" 28UNF-2A threaded stud base, while the S05 suffix indicates an M6 x 1 metric threaded stud base.

How does the reverse recovery time vary with temperature?

The typical reverse recovery time increases significantly at higher junction temperatures; for example, it rises from approximately 50 ns at 25 °C to 200 ns at 125 °C under similar dIF/dt conditions.
