HER156GH

Single Diodes Overview

The HER156GH is a glass passivated high-efficiency rectifier manufactured by Taiwan Semiconductor. It features a single configuration with a maximum repetitive peak reverse voltage of 400V and an average forward rectified current of 1.5A. The device utilizes a DO-204AC (DO-15) through-hole package. Key electrical characteristics include a fast recovery time of 75ns, a maximum non-repetitive peak forward surge current of 50A, and a low reverse leakage current of 5uA at rated voltage. It operates within a junction temperature range of -55°C to +150°C and holds AEC-Q101 qualification for automotive reliability.

Single Diodes Feature Summary

• Glass passivation provides mechanical strength and protects the silicon junction against mechanical stresses.
• Fast recovery characteristics enable high efficiency in switching applications.
• Low forward voltage drop minimizes power loss during conduction.
• High surge current capability ensures robustness against transient overloads.

Single Diodes Applications

• Automotive electronics systems requiring AEC-Q101 qualified components
• General purpose high-efficiency rectification circuits
• DC-DC converter output stages

Single Diodes Procurement Notes

Verify the specific suffix GH indicates the tape and reel packaging format rather than bulk or other configurations. Confirm the AEC-Q101 automotive qualification status directly with the manufacturer or authorized distributors. Ensure the DO-204AC package dimensions match your PCB footprint requirements before finalizing procurement.

Single Diodes Selection Notes

Select this component when a 400V reverse voltage rating and 1.5A continuous current are required in a standard axial leaded package. The 75ns recovery time makes it suitable for general-purpose high-frequency rectification where ultra-fast recovery is not strictly necessary but higher efficiency than standard rectifiers is desired. Consider thermal management for the DO-204AC package under high load conditions.

Single Diodes Part Context

This part belongs to the HER15x series of high-efficiency rectifiers from Taiwan Semiconductor. The series covers reverse voltages from 50V to 1000V with consistent 1.5A current ratings. The HER156 variant specifically targets 400V applications within this lineup, offering a balance of speed and voltage handling in a widely used DO-15 form factor.

Single Diodes Replacement Considerations

Cross-reference with HER156G from other manufacturers such as Gulf Semiconductor or Daco Semiconductor for equivalent specifications. Verify that substitute parts maintain the same 75ns recovery time and 400V rating. Ensure the replacement also meets AEC-Q101 standards if automotive application is required.
