Overview
The BYT78-TAP is a fast avalanche sinterglass diode manufactured by Vishay General Semiconductor - Diodes Division. It features a hermetically sealed SOD-64 package with plated axial leads. The device provides a repetitive peak reverse voltage of 1000 V and an average forward current of 3 A. Key electrical parameters include a maximum reverse recovery time of 250 ns, a typical forward voltage of 1.2 V at 3 A, and a non-repetitive reverse avalanche energy rating of 10 mJ. Operating temperatures range from -55 °C to +175 °C.
Feature Summary
- Glass passivated junction for enhanced reliability
- Soft recovery characteristics suitable for high-speed rectification
- Controlled avalanche characteristics for surge protection
- Hermetically sealed package design
Applications
- Fast soft recovery rectification circuits
- High-voltage power supply designs
- Industrial switching applications
Procurement Notes
Verify the specific ordering code BYT78-TAP corresponds to the 2500 units per ammopack configuration as documented in the manufacturer's ordering information. Confirm that the 12,500 unit minimum order quantity aligns with your procurement requirements before finalizing the purchase. Ensure compatibility with the SOD-64 through-hole mounting style.
Selection Notes
Select this component when a 1000 V reverse voltage rating and 3 A continuous forward current are required. The 250 ns reverse recovery time makes it appropriate for general-purpose fast rectification. Consider the controlled avalanche capability if the circuit requires handling specific surge conditions within the 10 mJ energy limit.
Part Context
This part belongs to the BYT77/BYT78 series of fast avalanche sinterglass diodes. While the BYT77 variant offers an 800 V rating, the BYT78 specifically provides a 1000 V rating. Both share identical physical dimensions, thermal characteristics, and packaging options, differing primarily in their maximum reverse voltage capabilities.
Replacement Considerations
Public confirmed substitute part numbers: None identified.
