BAT54CLT1

Overview

The BAT54CLT1 is a dual common cathode Schottky barrier diode designed for high-speed switching, circuit protection, and voltage clamping. It features extremely fast switching speed and low forward voltage (0.35 V typical at IF = 10 mA DC). The device operates with a reverse voltage of 30 V, maximum forward current of 200 mA, and peak non-repetitive forward current of 600 mA. Total capacitance is typically 7.6 pF, with a reverse recovery time of 5.0 ns. Power dissipation is 225 mW at 25°C ambient temperature. Junction temperature range spans from -55°C to +150°C.

Feature Summary

• Extremely fast switching speed suitable for high-frequency applications
• Low forward voltage reduces conduction loss in power circuits
• AEC-Q101 qualified and PPAP capable for automotive use

Applications

• High speed switching applications
• Circuit protection
• Voltage clamping

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and shipping quantity. Confirm RoHS compliance status and Pb-free designation as required by project specifications. Ensure the component meets AEC-Q101 qualification standards if intended for automotive environments. Validate that the selected variant matches the required pin configuration and thermal characteristics.

Selection Notes

Select this component when space is limited due to its miniature surface mount package. Consider the low forward voltage characteristic for efficiency-critical designs. Verify compatibility with high-speed switching requirements given the 5.0 ns reverse recovery time. Ensure the operating junction temperature range aligns with the environmental conditions of the target application.
