BYM36B-TAP

Overview

The BYM36B-TAP is a high-voltage avalanche rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 400V and an average forward rectified current of 3A. The device utilizes a glass-passivated junction for reliability and is housed in a compact SOD-64 axial leaded package. Designed for robust performance, it exhibits very low switching losses and low reverse leakage current, making it suitable for demanding power conversion applications requiring efficient high-voltage rectification.

Feature Summary

• Glass-passivated junction construction for enhanced environmental stability
• Hermetically sealed package design ensuring long-term reliability
• Optimized for minimal switching energy dissipation during operation
• Engineered for low reverse current to improve efficiency

Applications

• High-voltage DC-DC converter circuits
• Flyback transformer rectification stages
• Industrial power supply output stages
• Inverter freewheeling paths

Procurement Notes

Verify the specific suffix 'TAP' corresponds to the axial tape-and-reel packaging format required for your assembly line equipment. Confirm that the 400V rating aligns with your circuit's transient voltage requirements. Ensure the SOD-64 package dimensions fit within your PCB footprint constraints. Check for RoHS compliance status if your manufacturing process mandates specific environmental standards. Validate supplier authenticity through authorized distribution channels.

Selection Notes

Select this component when a 400V blocking capability and 3A continuous current are necessary within a small axial form factor. Consider its low switching loss characteristics for high-frequency applications where thermal management is critical. Compare against standard rectifiers if faster recovery times are needed, noting its avalanche ruggedness. Evaluate the hermetic seal requirement against cost-sensitive alternatives if environmental sealing is not mandatory for the target application environment.

Part Context

This part belongs to Vishay's BYM series of high-voltage avalanche rectifiers. These devices are engineered to withstand high-energy avalanche conditions without degradation. The series typically offers a range of voltage ratings from 100V to 800V, allowing designers to select appropriate breakdown voltages for various power supply topologies while maintaining consistent package and electrical characteristics across the family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with generic 400V 3A axial rectifiers only after confirming pinout and thermal specifications match exactly.
