BY269TAP

Overview

The BY269TAP is a fast avalanche sinterglass diode from Vishay, featuring an SOD-57 axial package. It supports a reverse voltage of 1600 V and an average forward current of 0.8 A. The device exhibits a maximum reverse recovery time of 400 ns and a peak non-repetitive reverse voltage of 1800 V. It operates within a junction temperature range of -55 °C to +175 °C.

Feature Summary

• Hermetically sealed glass passivated junction for high reliability
• Fast avalanche capability with low leakage characteristics
• High surge overload rating supporting peak currents up to 20 A

Applications

• High voltage fast rectification circuits
• Industrial power supply designs
• General purpose high voltage switching applications

Procurement Notes

Verify the specific ordering code BY269TAP corresponds to the ammopack configuration containing 5000 units per pack. Confirm that the minimum order quantity aligns with the manufacturer's standard requirement of 25,000 units for this packaging format before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring robust high-voltage handling and fast recovery speeds. Ensure the thermal resistance constraints are met by evaluating lead length and PCB spacing, as these factors significantly influence the maximum allowable forward current and junction temperature limits.

Part Context

This part belongs to the BY268/BY269 series of fast avalanche sinterglass diodes manufactured by Vishay Semiconductors. The series utilizes hermetically sealed packages designed for high reliability in demanding environments, offering distinct voltage ratings between the 1400 V BY268 and the 1600 V BY269 variants.

Replacement Considerations

Cross-reference with the BY268 if a lower voltage rating of 1400 V is acceptable. Verify mechanical compatibility with the SOD-57 package and ensure electrical parameters such as reverse recovery time and peak surge current meet or exceed the original design requirements.
