Overview
The BYT54M-TAP is a fast avalanche sinterglass diode manufactured by Vishay Semiconductors. It features a glass passivated junction and a hermetically sealed SOD-57 package with plated axial leads. The device supports an average forward current of 1.25 A at a lead length of 10 mm, or 0.75 A on a printed circuit board. It withstands a repetitive peak reverse voltage of 1000 V and offers a non-repetitive reverse avalanche energy rating of 10 mJ. The component operates within a junction temperature range of -55 °C to +175 °C.
Feature Summary
- Glass passivated junction for high reliability
- Hermetically sealed package construction
- Soft recovery characteristics for efficient switching
- Low reverse leakage current
Applications
- Very fast rectification circuits
- High-speed switching applications
Procurement Notes
Verify the specific ordering code BYT54M-TAP against official documentation to confirm packaging details. The datasheet indicates this variant is supplied in an ammopack containing 5000 units per pack. Ensure compliance with environmental standards as defined in the material categorization section of the manufacturer's documentation before finalizing procurement.
Selection Notes
Select the BYT54M-TAP when a 1000 V blocking capability is required alongside avalanche energy handling. The SOD-57 form factor suits through-hole mounting where soft recovery behavior minimizes electromagnetic interference during switching transitions. Evaluate thermal resistance requirements based on the specific lead length or PCB spacing conditions provided in the datasheet.
Part Context
This component belongs to the BYT54 series of fast avalanche sinterglass diodes from Vishay Semiconductors. The series includes variants with different reverse voltage ratings ranging from 50 V to 800 V. The 'M' suffix specifically designates the 1000 V version within this family of glass-passivated rectifiers designed for robust performance in demanding electronic environments.
Replacement Considerations
Direct substitutes include other BYT54 series parts such as BYT54K or BYT54J if lower voltage ratings are acceptable. Cross-reference electrical parameters like reverse recovery time and forward voltage with alternative manufacturers' fast recovery diodes to ensure compatibility with existing circuit designs.
