UH6PJHM3/86A

Single Diodes Overview

The UH6PJHM3/86A is a high current density surface mount ultrafast high voltage rectifier manufactured by Vishay General Semiconductor. It utilizes the eSMP series TO-277A (SMPC) package and features an oxide planar chip junction. The device is rated for a maximum repetitive peak reverse voltage of 600 V and a maximum average forward rectified current of 6.0 A at 25 °C. It supports a peak forward surge current of 80 A and operates within a junction temperature range of -55 to +175 °C. Electrical characteristics include a typical reverse recovery time of 25 ns, a typical forward voltage of 1.3 V at 6.0 A, and a maximum reverse current of 10 µA at 25 °C.

Single Diodes Procurement Notes

Verify that the specific ordering suffix matches the required automotive grade HM3 variant rather than the commercial M3 version. Confirm the delivery mode corresponds to the 86A code for 7-inch tape and reel packaging. Ensure compliance with RoHS and halogen-free requirements as specified in the datasheet before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when designing circuits requiring high voltage isolation up to 600 V combined with fast switching speeds. The TO-277A package provides a compact footprint ideal for space-constrained PCB layouts. Consider the thermal resistance values when determining heatsinking requirements for continuous high-current applications exceeding standard derating curves.

Single Diodes Part Context

This part belongs to the Vishay eSMP series of ultrafast rectifiers designed for surface mount technology. It shares the physical dimensions and pinout configuration with other devices in the TO-277A family, facilitating board layout reuse across different voltage or current ratings within the same product line.

Single Diodes Replacement Considerations

Direct substitutes include the UH6PJ-M3/86A for commercial grade applications. Verify electrical parameters such as reverse recovery time and forward voltage drop against the original design specifications to ensure compatibility.

Single Diodes FAQ
