BAT54T

Overview

The BAT54T is a single Schottky barrier diode manufactured by Taiwan Semiconductor Corporation. It features a SOT-363 surface mount package and operates with a maximum repetitive peak reverse voltage of 30 V. The device supports a continuous forward current of 200 mA and a non-repetitive peak forward surge current of 600 mA. Electrical characteristics include a maximum forward voltage of 1 V at 100 mA, a reverse current of 2 μA at rated voltage, and a junction capacitance of 10 pF. The component functions within a junction temperature range of -65 to +150 °C.

Feature Summary

• Low forward voltage drop for efficient power handling
• RoHS compliant and halogen-free construction

Applications

• Voltage clamping
• Reverse polarity protection
• High speed switching

Procurement Notes

Verify the specific ordering code against the manufacturer's official documentation to ensure correct packaging and configuration. Confirm that the selected variant matches the required electrical parameters and mechanical footprint for the intended circuit design. Cross-reference datasheet specifications with actual component markings to validate authenticity and performance ratings before integration.

Selection Notes

Select this component based on its 30 V reverse voltage rating and 200 mA forward current capacity. Ensure the SOT-363 package dimensions align with the PCB layout requirements. Consider the thermal resistance and operating temperature limits when designing for environments exceeding standard ambient conditions. Verify compliance with moisture sensitivity levels if reflow soldering processes are utilized.
