Overview
The BYT53G-TAP is an ultra-fast avalanche sinterglass diode manufactured by Vishay Semiconductors. It features a glass passivated junction and a hermetically sealed SOD-57 axial leaded package. The device supports a maximum repetitive peak reverse voltage of 400 V and an average forward current of 1.9 A. Key electrical characteristics include a maximum reverse recovery time of 50 ns, a typical forward voltage of 1.1 V at 1 A, and a low reverse leakage current of 5 µA at rated voltage. It operates within a junction temperature range of -55 °C to +175 °C.
Feature Summary
- Ultra-fast avalanche capability with soft recovery characteristics
- Hermetically sealed glass passivated junction for reliability
- Low reverse current operation
Applications
- Very fast rectification and switching circuits
- Switched mode power supplies
- High-frequency inverter circuits
Procurement Notes
Verify the specific ordering code BYT53G-TAP against the datasheet to confirm the ammpack packaging format. Ensure the required minimum order quantity aligns with the manufacturer's standard packing specifications. Confirm that the 400 V rating matches the circuit requirements before finalizing procurement.
Selection Notes
Select this component when high-speed switching and avalanche ruggedness are required in a through-hole package. The 400 V rating distinguishes it from lower voltage variants like the BYT53B or BYT53C. Consider the thermal resistance limits and derating curves for ambient temperatures exceeding 25 °C during design validation.
Part Context
This part belongs to the BYT53 series of ultra-fast avalanche sinterglass diodes. The series includes multiple voltage ratings (50 V to 300 V) sharing the same SOD-57 package and general electrical profile. The 'G' suffix specifically denotes the 400 V breakdown voltage variant within this family.
Replacement Considerations
Direct substitutes must match the 400 V reverse voltage, 1.9 A average current, and 50 ns reverse recovery time. Verify compatibility with the SOD-57 axial leaded package and ensure the replacement device also supports avalanche energy ratings if transient protection is required.
