BAT54CT-HF

Overview

The BAT54CT-HF is a small signal Schottky diode manufactured by Comchip Technology, housed in an SOT-523 package. It features a dual anode common cathode configuration using silicon technology. Key electrical parameters include a maximum repetitive reverse voltage of 30 V and a forward current of 200 mA. The device exhibits a typical forward voltage of 520 mV and a peak forward surge current rating of 600 mA. Reverse leakage current is specified at 2 mA. Power dissipation is rated at 225 mW, with an operating temperature range spanning from -55°C to +125°C.

Feature Summary

• Dual anode common cathode configuration for efficient circuit integration
• Low forward voltage drop characteristic for improved efficiency
• High speed switching capability suitable for small signal applications

Applications

• Signal rectification in low voltage circuits
• Clamping and protection in high-speed data lines
• Logic level shifting and OR gate implementations

Procurement Notes

Verify the specific suffix 'CT' to confirm the dual anode common cathode configuration, as other variants may differ electrically. Ensure the SOT-523 package matches the target PCB footprint requirements. Cross-reference the RoHS compliance status with the latest manufacturer documentation before finalizing component selection for regulated assemblies.

Selection Notes

Select this component when a compact dual Schottky solution is required within limited board space constraints. The SOT-523 package offers a smaller profile compared to standard SOT-23 options. Consider the 30 V reverse voltage limit and 200 mA forward current capacity to ensure adequate margins for the intended application's electrical stress conditions.
