BAT54STA

Overview

The BAT54STA is a surface mount Schottky barrier diode manufactured by Diodes Incorporated, housed in an SOT23 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 reverse leakage current of 2µA at 25V. Total capacitance is 10pF at 1V, and the reverse recovery time is 5ns. Power dissipation is rated at 200mW, operating within a temperature range of -65°C to +150°C.

Feature Summary

• Low turn-on voltage for efficient power handling
• Fast switching capability for high-speed applications
• PN junction guard ring integrated for transient and ESD protection

Applications

• Ultra high-speed switching circuits
• Voltage clamping applications
• Protection circuits requiring ESD tolerance

Procurement Notes

Verify the specific part number BAT54STA against the official Diodes Incorporated datasheet DS44979 Rev. 1-2 to confirm manufacturing origin and compliance status. Ensure that the ordering suffix TA corresponds to the tape and reel packaging format as documented. Cross-reference the JEDEC qualification standards mentioned in the product summary to validate suitability for high-reliability requirements before finalizing procurement.

Selection Notes

Select this component when a low forward voltage drop and rapid switching speed are required in a compact SOT23 footprint. The integrated PN junction guard ring makes it suitable for environments susceptible to transient voltage spikes or electrostatic discharge events. Consider the 200mA continuous current rating and 200mW power dissipation limits during thermal design to ensure reliable operation within the specified temperature range.

Part Context

This device belongs to the BAT54 series of surface mount Schottky barrier diodes produced by Diodes Incorporated. The 'STA' suffix specifically denotes the BAT54S configuration (series connection) packaged in SOT23 and supplied in tape and reel format. This series is designed to offer low conduction losses and fast response times compared to standard silicon rectifiers.
