BAT54S-7-F

Overview

The BAT54S-7-F is a surface-mount Schottky barrier diode manufactured by Diodes Incorporated, housed in an SOT23 (Standard) package. It features a peak repetitive reverse voltage of 30V and an average rectified output current of 200mA. The maximum forward voltage is 800mV at 100mA, with a maximum reverse leakage current of 2μA at 25V. Total capacitance is 10pF at 1.0V, and the reverse recovery time is 5ns. Power dissipation is rated at 200mW, with a thermal resistance junction-to-ambient of 500°C/W. Operating temperature ranges from -65°C to +150°C.

Feature Summary

Low turn-on voltage for efficient conduction
Fast switching capability with minimal reverse recovery time
PN Junction Guard Ring integrated for transient and ESD protection

Applications

High-speed switching circuits
Voltage clamping applications
Reverse polarity protection

Procurement Notes

Verify the component against the official Diodes Incorporated datasheet DS11005 Rev. 34 to confirm authenticity. Ensure the marking code matches KL4 for the BAT54S variant. Check that the device is fully RoHS compliant and free of halogens and antimony as specified in the manufacturer's green product definitions.

Selection Notes

Select this component when a low forward voltage drop and rapid switching speed are required in a compact SOT23 footprint. The integrated guard ring makes it suitable for environments requiring robust transient and electrostatic discharge protection. Verify that the 200mA current rating and 30V reverse voltage align with the specific circuit requirements.

Part Context

This part belongs to the BAT54 series of surface-mount Schottky barrier diodes. The 'S' suffix denotes specific electrical characteristics within the family, distinguishing it from variants like BAT54A or BAT54C. The '-7-F' suffix indicates standard tape and reel packaging containing 3,000 units per carrier.
