B0540WS-HF

Overview

The B0540WS-HF is a surface-mount Schottky barrier diode manufactured by Comchip Technology. It features a single configuration in an SOD-323 package. Key electrical parameters include a maximum repetitive reverse voltage (Vrrm) of 40 V and a forward current (If) of 500 mA. The device exhibits a maximum forward voltage (Vf) of 800 mV at rated current and a low reverse leakage current (Ir) of 6 µA. It supports a forward surge current (Ifsm) of 2 A and operates within a junction temperature range of -55 °C to +125 °C.

Feature Summary

• Schottky barrier construction for high switching efficiency
• Low forward voltage drop to minimize power loss
• Fast recovery time suitable for high-frequency applications

Applications

• DC-DC converters
• Power supply rectification
• Polarity protection circuits

Procurement Notes

Verify the complete part number including the suffix against official manufacturer documentation to ensure correct specifications. Confirm RoHS compliance status and specific packaging details such as reel or cut tape options directly with authorized distributors prior to ordering.

Selection Notes

Select this component when a compact surface-mount solution is required for low-voltage, moderate-current rectification. Ensure the circuit design accounts for the 40 V reverse voltage rating and thermal management within the specified operating temperature range.

Part Context

This component belongs to the Schottky diodes and rectifiers category from Comchip Technology. It is designed for general-purpose rectification tasks where low forward voltage and fast switching are prioritized over high voltage blocking capabilities.

Replacement Considerations

Consult official substitution guides for compatible equivalents. Verify pinout compatibility and electrical parameter margins before replacing.
