BA158GH

Overview

The BA158GH is a fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a single silicon junction with a maximum repetitive peak reverse voltage of 600 V and an average forward rectified current of 1 A. The device utilizes a DO-204AL (DO-41) axial leaded package. Key electrical characteristics include a maximum forward voltage of 1.3 V at 1 A, a reverse leakage current of 5 µA at 600 V, and a typical reverse recovery time of 250 ns. It supports a maximum non-repetitive peak forward surge current of 30 A and operates within a junction temperature range of -65°C to 150°C.

Feature Summary

• Fast recovery performance with low power loss for high efficiency
• Glass passivated chip junction for enhanced reliability
• High surge current capability suitable for demanding applications

Applications

• General purpose rectification in power supplies
• Free wheeling diodes in inductive load circuits
• DC-DC converter output rectification

Procurement Notes

Verify the specific suffix GH against the manufacturer's official datasheet to confirm halogen-free status and packaging details. Ensure the ordering part number matches the required RoHS compliance and environmental specifications. Cross-reference the DO-204AL package dimensions with your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a 600 V rating and 1 A continuous current are required with fast switching characteristics. Compare the 250 ns reverse recovery time against circuit switching frequencies to ensure minimal switching losses. Verify that the thermal management design accommodates the 150°C maximum junction temperature limit under expected load conditions.

Part Context

This component belongs to the BA15x series of fast recovery plastic rectifiers from Taiwan Semiconductor. The series typically covers voltage ratings from 400 V to 1000 V with a consistent 1 A current capacity. The BA158 variant specifically targets 600 V applications, distinguishing it from lower or higher voltage siblings like the BA157 or BA159 within the same product family.

Replacement Considerations

Compatible substitutes include the BA158-E3/54 from Vishay and other generic BA158 equivalents from manufacturers such as Diodes Incorporated or Onsemi. Ensure replacement parts match the DO-204AL package and maintain equivalent reverse recovery time and voltage ratings.
