1N5391G R0G

Overview

The 1N5391G R0G is a standard rectifier from the 1N5391G–1N5399G series by Taiwan Semiconductor, housed in a DO-204AC (DO-15) package. It features a single die configuration with glass passivated chip junctions. Key electrical parameters include a forward current (IF) of 1.5 A and a repetitive peak reverse voltage (VRRM) range of 50 V to 1000 V across the series, with the 1N5391G specifically rated at 50 V. The device supports a surge peak forward current (IFSM) of 50 A for an 8.3 ms half-sine wave. Maximum junction temperature (TJ MAX) is 150 °C, with a typical junction-to-ambient thermal resistance of 65 °C/W.

Feature Summary

• Glass passivated chip junction construction
• High efficiency with low forward voltage drop
• AEC-Q101 qualified variants available

Applications

• DC to DC converter circuits
• Switching mode converters and inverters
• General purpose rectification

Procurement Notes

Verify the specific ordering suffix against the datasheet to confirm packaging type and qualification status. The base model denotes the voltage rating, while suffixes such as 'H' indicate AEC-Q101 automotive qualification. Packaging options include tape & reel or ammo box configurations. Ensure the selected part matches the required voltage class within the 50 V to 1000 V range defined by the series numbering system.

Selection Notes

Select this component for applications requiring a 1.5 A continuous forward current capability in a DO-204AC package. The 1N5391G variant is suitable for circuits needing a 50 V repetitive peak reverse voltage rating. Consider the thermal performance with a junction-to-ambient resistance of 65 °C/W when designing heat dissipation strategies. Verify if AEC-Q101 qualification is necessary for the target application environment.

Part Context

This component belongs to the 1N5391G through 1N5399G series of 1.5 A standard rectifiers manufactured by Taiwan Semiconductor. The series covers a voltage range from 50 V to 1000 V, differentiated by the last digit of the part number. All variants share the same DO-204AC (DO-15) mechanical outline and general electrical characteristics, differing primarily in their maximum reverse voltage ratings.

Replacement Considerations

Direct substitutes within the same series include 1N5392G through 1N5399G, provided the voltage rating meets circuit requirements. Cross-brand equivalents must match the 1.5 A forward current, 50 V reverse voltage, and DO-204AC package dimensions. Verify that any replacement maintains the same glass passivation technology and thermal resistance specifications.
