BAT54S-QR Description

Short technical summary and product information.

The BAT54S-QR from Nexperia is a Schottky barrier diode array containing two series-connected diodes with an integrated guard ring for stress protection. It is designed for ultra high-speed switching, line termination, voltage clamping, and reverse polarity protection applications.

 

Key electrical specifications include a maximum reverse voltage of 30 V, a continuous forward current of 200 mA, and a forward voltage of 800 mV at 100 mA. The reverse leakage current is as low as 2 µA at 25 V. The device is qualified according to AEC-Q101 and is recommended for use in automotive applications.

 

The diode array is housed in a small SOT23 (TO-236AB) surface-mount plastic package, measuring 2.9 mm x 1.3 mm x 1 mm. It supports a junction temperature of up to 150 °C and has a total power dissipation of 250 mW on an FR4 PCB. The low forward voltage and low capacitance make it suitable for high-speed switching circuits.
