BA159G

Overview

The BA159G is a fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a single silicon junction housed in an isolated DO-41 plastic package with axial leads. The device supports a maximum average forward rectified current of 1 A and a repetitive peak reverse voltage of 1000 V. Key electrical characteristics include a fast reverse recovery time of 250 ns and a low forward voltage drop. It operates within a temperature range of -55 °C to 150 °C, ensuring high reliability and low power loss for efficient circuit performance.

Feature Summary

• Fast switching capability with 250 ns reverse recovery time
• High reliability construction with low power loss
• Isolated case connection for flexible mounting

Applications

• High frequency rectification circuits
• Free wheeling diode applications
• DC-DC converter output rectification

Procurement Notes

Verify the specific suffix 'G' against the manufacturer's official datasheet to confirm compliance with RoHS directives and lead-free plating requirements. Ensure the ordering part number matches the exact voltage rating and package style required for your design. Cross-reference the JEDEC code DO-204AL to confirm physical dimensions and pin configuration compatibility with your PCB footprint.

Selection Notes

Select this component when designing circuits requiring fast recovery characteristics at 1000 V reverse voltage. The DO-41 package provides robust mechanical stability for through-hole assembly. Consider the 150 °C maximum junction temperature for thermal management in high-load environments. Verify that the 250 ns recovery time meets the switching speed requirements of your specific application to minimize switching losses.

Part Context

This component belongs to the BA15x series of fast recovery rectifiers from Taiwan Semiconductor. The series typically includes variants with different voltage ratings such as 400 V, 600 V, and 800 V. The BA159G specifically denotes the 1000 V rating within this lineup. These diodes are designed for general-purpose high-speed rectification in consumer and industrial electronics.

Replacement Considerations

Compatible substitutes include Vishay BA159GP-E3/54 and MCC BA159GP-AP. Verify that replacement parts maintain the same 1 A current rating, 1000 V voltage rating, and DO-41 package form factor. Confirm equivalent reverse recovery times to ensure no degradation in circuit switching performance.
