BAT54S SOT23-3 Dual Schottky Diode – Hottech KL4 Marking

Product Description:

The BAT54S KL4 SOT23 Schottky Diode from Hottech is a dual Schottky diode designed for high-speed switching, low forward voltage applications, and precision signal routing. Encased in a compact SOT-23 package, the BAT54S integrates two Schottky diodes in a series configuration, making it ideal for clamping, polarity protection, OR-ing circuits, power management, and high-frequency applications.

With its low forward voltage drop, fast recovery characteristics, and low leakage current, this diode is widely used in portable devices, DC–DC converters, logic-level shifting, small power circuits, and RF modules. The KL4 marking identifies the genuine Hottech BAT54S variant.
