BA159DGPHE3/54

Overview

The BA159DGPHE3/54 is a glass-passivated silicon rectifier diode manufactured by Vishay General Semiconductor. It features a single diode configuration in a DO-204AL (DO-41) axial through-hole package. The device supports a maximum repetitive peak reverse voltage of 800 V and an average forward rectified current of 1 A. Key electrical characteristics include a maximum forward voltage of 1.3 V at 1 A, a reverse leakage current of 5 µA at 800 V, and a peak reverse recovery time of 500 ns. It operates within a junction temperature range of -65°C to 175°C.

Feature Summary

• Glass passivation provides mechanical strength and protects the junction against mechanical stresses.
• Metalurgically bonded construction ensures reliable operation under high thermal conditions.
• Axial leaded design facilitates easy insertion into printed circuit boards for through-hole mounting.

Applications

• High voltage power supply circuits
• Freewheeling protection in inductive load switching
• General purpose rectification in industrial equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated by the E3 suffix. Check for end-of-life notifications or obsolescence warnings prior to procurement. Ensure storage conditions meet specified humidity sensitivity levels. Validate packaging type matches project requirements for automated assembly or manual placement.

Selection Notes

Select this component when a high-voltage 800V rating is required with standard recovery characteristics. Compare against BA159 variants if different voltage ratings are needed. Consider thermal management capabilities given the 175°C maximum junction temperature. Evaluate package constraints for DO-204AL footprint availability. Assess reverse recovery speed suitability for specific switching frequencies.

Part Context

This part belongs to the BA15x series of general-purpose rectifiers from Vishay. The series includes variants with different voltage ratings such as 400V (BA157), 600V (BA158), and 1000V (BA159). The GP suffix typically denotes glass passivation, while HE may indicate specific environmental or handling enhancements. These diodes are designed for robust performance in demanding electronic applications.

Replacement Considerations

Direct substitutes include BA159-E3/54 for 1000V applications if voltage margin allows. BA158-E3/54 offers lower voltage rating but similar current handling. Verify pinout compatibility and thermal resistance values before substitution. Ensure replacement parts meet same regulatory standards and package dimensions.
