BAT54CLT3G

Overview

The BAT54CLT3G is a dual common cathode Schottky barrier diode manufactured by onsemi in an SOT-23 surface-mount package. It features a maximum reverse voltage of 30 V and a continuous forward current rating of 200 mA. The device exhibits extremely fast switching with a reverse recovery time of 5 ns and low forward voltage, typically 0.35 V at 10 mA DC. Total capacitance is 7.6 pF typical at 1.0 V reverse bias. It operates within a junction temperature range of -55°C to +150°C and dissipates up to 225 mW.

Feature Summary

• Extremely fast switching speed suitable for high-frequency applications
• Low forward voltage reduces conduction loss
• Miniature surface mount package ideal for space-limited designs

Applications

• High-speed switching circuits
• Circuit protection
• Voltage clamping
• Hand-held and portable devices

Procurement Notes

Verify the specific ordering suffix 'T3G' corresponds to the 10,000-unit tape and reel packaging configuration as defined in the official datasheet. Confirm that the component meets RoHS compliance and lead-free requirements if specified for the target assembly process. Ensure the automotive prefix 'S' is not required unless AEC-Q101 qualification and PPAP capability are explicitly needed for the application.

Selection Notes

Select this component when low forward voltage drop and rapid reverse recovery are critical for system efficiency and signal integrity. The dual common cathode configuration allows for compact implementation of rectification or logic functions. Consider the thermal resistance and power dissipation limits relative to the ambient operating conditions and PCB pad layout to ensure reliable operation within the specified temperature range.

Part Context

This part belongs to the BAT54CL series of dual common cathode Schottky barrier diodes from onsemi. It shares functional characteristics with variants like the BAT54CLT1G, differing primarily in shipping quantity and packaging format. The series is designed for general-purpose high-speed switching and protection in miniature electronic assemblies.
