B0540WHE3-TP

Overview

The B0540WHE3-TP is a Schottky barrier rectifier manufactured by Micro Commercial Components (MCC). It features a maximum repetitive peak reverse voltage of 40 V and an average forward rectified current of 500 mA. The device utilizes a SOD-123 surface-mount package. Key electrical characteristics include a maximum DC reverse leakage current of 80 µA at 40 V, a typical junction capacitance of 30 pF at 4 V and 1 MHz, and a maximum forward voltage drop of 550 mV at 500 mA. The component operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards
• Low forward voltage drop for improved power efficiency
• Fast switching speed with minimal reverse recovery charge
• Halogen-free construction compliant with RoHS directives

Applications

• Automotive electronics systems requiring qualified components
• DC-DC converter circuits in power supplies
• Free-wheeling diodes in inductive load protection
• Polarity protection in low-voltage DC circuits

Procurement Notes

Verify the specific suffix HE3 against official MCC documentation to confirm halogen-free status and automotive qualification. Ensure the ordering part number matches the exact package type and electrical ratings required for the design. Cross-reference datasheet revisions to confirm compliance with current environmental regulations such as RoHS3. Confirm availability through authorized distributors as supply levels may vary.

Selection Notes

Select this component when a small surface-mount Schottky rectifier with automotive certification is required. The SOD-123 package suits space-constrained PCB layouts. Verify that the 40 V reverse voltage rating exceeds the circuit's peak inverse voltage. Ensure the 500 mA current capacity meets the application's continuous load requirements while accounting for thermal derating at elevated temperatures.

Part Context

This part belongs to the B0540 series of Schottky rectifiers from Micro Commercial Components. The HE3 suffix typically denotes a halogen-free variant within the product line. The series is designed for general-purpose rectification and clamping applications where low forward voltage and fast switching are critical. It complements other MCC discrete semiconductor offerings for consumer and industrial markets.

Replacement Considerations

Consult official MCC substitution guides or equivalent manufacturer cross-reference lists for verified alternatives. Ensure any substitute maintains the SOD-123 footprint, 40 V rating, 500 mA current capacity, and AEC-Q101 qualification if automotive use is intended.
