BAT41 Small Signal Schottky Diode, Single, 100V 100mA

The BAT41 from STMicroelectronics is a general-purpose metal-to-silicon small signal Schottky diode, engineered for applications demanding high-speed performance and energy efficiency. Its design features extremely fast switching capabilities, coupled with low forward and reverse recovery times, making it specially suited for switching-mode power supplies where low reverse recovery losses are critical. This integration helps to maximise overall system efficiency.

A key advantage of this device is its very low conduction and negligible switching losses, which contribute to reduced power dissipation and improved thermal management in compact circuits. Constructed as a surface-mount device (SMD), it offers a low capacitance profile, further enhancing its high-frequency performance. The diode is built to withstand demanding operating conditions, with a maximum operating junction temperature of 150°C.

For enhanced reliability, the BAT41 includes integrated protection against excessive voltage transients such as electrostatic discharges (ESD), providing an added layer of durability in sensitive electronic environments. Its through-hole mounting style in a DO-35 (DO-204AH) case ensures secure and straightforward PCB integration, suitable for both prototyping and volume production.

With its robust specifications and focused design, the BAT41 is an excellent choice for designers seeking a reliable, fast-switching diode for precision circuitry.
