Overview
The BYT52B-TAP is a 100 V, 1.4 A avalanche diode manufactured by Vishay General Semiconductor - Diodes Division. It utilizes the SOD-57 surface-mount package and operates within a junction temperature range of -55°C to 175°C. The component features a maximum reverse leakage current of 5 µA at 200 V and supports peak pulse currents consistent with its avalanche rating. It is RoHS compliant and classified under ECCN EAR99.
Feature Summary
- Engineered for avalanche mode operation to handle repetitive energy pulses
- Designed for high-temperature stability with a junction rating up to 175°C
- Utilizes compact SOD-57 surface-mount packaging for space-constrained applications
Applications
- Transient voltage suppression in low-voltage circuits
- Protection against inductive load switching spikes
- Clamping applications in automotive electronics
Procurement Notes
Verify the specific suffix TAP corresponds to the required tape-and-reel quantity and orientation. Confirm that the SOD-57 footprint matches the target PCB design. Ensure the application environment remains within the specified -55°C to 175°C junction temperature limits to maintain reliability. Check for any recent Product Change Notifications regarding manufacturing location or material composition changes.
Selection Notes
Select this component when avalanche-rated protection is required rather than standard Zener breakdown. The 1.4 A current rating and 100 V standoff voltage define the operational boundaries. Consider the thermal management requirements associated with the small SOD-57 package. Compare alternative packages if higher power dissipation or different mounting styles are necessary for the specific system design.
Part Context
This part belongs to Vishay's BYT series of avalanche diodes, which are distinct from standard Zener diodes due to their ability to operate safely in the breakdown region. The series is designed for robust transient protection in environments where standard diodes might fail under repetitive surge conditions.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with equivalent avalanche diodes from other manufacturers based on voltage, current, and package dimensions.
