BAT54SW,115

Overview

The BAT54SW,115 is a dual Schottky barrier diode manufactured by Nexperia. It utilizes silicon planar technology and is housed in an SOT-323 (SC-70) surface-mount package with three terminals. The device features a maximum repetitive reverse voltage of 30 V and supports a continuous forward current of 200 mA. Key electrical parameters include a maximum forward voltage of 800 mV at 100 mA, a peak forward surge current of 600 mA, and a maximum reverse leakage current of 2 uA. It operates within a temperature range of -65 °C to +125 °C.

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm exact packaging and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a compact dual Schottky solution is required for low-voltage signal processing or power rectification. The SOT-323 package offers space efficiency for dense PCB layouts. Consider the 30 V reverse voltage rating and 200 mA current capacity to ensure adequate headroom for the intended circuit operation under varying thermal conditions.

Part Context

This component belongs to the Nexperia BAT54S series of planar Schottky barrier diodes. The series is characterized by its small Surface-Mounted Device plastic package and integrated guard ring structure. These devices are engineered to provide robust performance in consumer electronics and communication equipment requiring reliable high-frequency rectification and fast switching capabilities.

Replacement Considerations

Compatible substitutes within the same family include BAT54A, BAT54B, and BAT54C, which share identical pinouts and mechanical dimensions but differ in forward voltage characteristics. Verify that alternative part numbers meet the specific voltage drop requirements of the application before substitution.
