RB078RSM15STFTL1

Single Diodes Overview

The RB078RSM15STFTL1 is a surface-mount Schottky barrier diode manufactured by ROHM Semiconductor. It features a single configuration housed in a TO-277A package. The device supports an average rectified forward current of 5 A and a repetitive reverse voltage of 150 V. Key electrical parameters include a maximum forward voltage of 0.87 V at 5 A, a peak forward surge current of 120 A, and a maximum reverse current of 2.1 mA at 150 V. It operates within a junction temperature range up to +175 °C and complies with the AEC-Q101 automotive grade standard.

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm the tape-and-reel packaging quantity and variant details. Ensure the component meets the required AEC-Q101 qualification level for automotive integration. Cross-reference the TO-277A package dimensions with your PCB footprint library before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when low reverse leakage current is critical for standby power consumption or signal integrity. The 150 V rating suits intermediate voltage bus applications. Verify that the 5 A continuous current capability aligns with the thermal management strategy of the target enclosure.

Single Diodes Part Context

This part belongs to the RB078 series of ultra-low IR Schottky barrier diodes designed specifically for automotive electronics. The series emphasizes high reliability and low power loss, making it suitable for strict automotive environmental conditions and efficiency requirements.

Single Diodes Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio that match the 150 V, 5 A, and TO-277A specifications while maintaining AEC-Q101 compliance.
