BAW56

Overview

The Taiwan Semiconductor BAW56 is a small signal switching diode housed in an SOT-23 package. It features a repetitive peak reverse voltage of 70 V and a forward current rating of 200 mA. The device supports a non-repetitive peak forward surge current of 2 A at 1 µs. Electrical characteristics include a maximum forward voltage of 1.25 V at 150 mA, a reverse recovery time of 6 ns, and a junction capacitance of 2 pF. Power dissipation is rated at 225 mW, with an operating temperature range from -55 °C to +150 °C.

Feature Summary

• Fast switching speed suitable for high-frequency applications
• Moisture sensitivity level 1 compliant per J-STD-020
• Halogen-free molding compound meeting IEC 61249-2-21 standards

Applications

• Switching mode power supply (SMPS)

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details. Confirm RoHS compliance status and halogen-free certification requirements prior to procurement. Ensure the selected variant matches the required tape and reel specifications for automated placement processes.

Selection Notes

Select this component for circuits requiring fast recovery times and low junction capacitance. Verify that the 70 V reverse voltage rating exceeds the circuit's peak inverse voltage. Check thermal resistance parameters to ensure adequate heat dissipation within the specified ambient temperature limits.

Part Context

This part belongs to the BAW56 series manufactured by Taiwan Semiconductor Corporation. It utilizes silicon epitaxial planar construction within a surface-mount SOT-23 case. The device is designed for general-purpose switching applications where compact size and rapid response are critical.

Replacement Considerations

BAV70 and BAV99 are electrically similar devices within the same series offering different circuit configurations.
