Product details

Schottky diode for low-power rail and signal protection

Its Schottky barrier construction delivers a fast 5 ns reverse recovery time and a low forward voltage drop of 800 mV at 100 mA, making it suited for high-speed switching applications such as polarity protection, freewheeling, and signal clamping in low-voltage circuits. The diode comes in a standard SOT-23-3 surface-mount package (PG-SOT23-3-11), compatible with common board-level footprints.

This diode fits low-side rectification, flyback catch diodes in relay or solenoid drivers, and ESD clamping on signal lines up to 30 V. The 2 µA reverse leakage at 25 V is typical for a small-signal Schottky and acceptable for most battery-powered designs. The 10 pF junction capacitance at 1 V helps maintain signal integrity in fast digital or RF paths.

No last-time-buy or discontinuation notice is in effect. For dual-sourcing, the BAT54 series includes multiple pin-compatible variants (BAT54, BAT54A, BAT54C, BAT54S) that share the same SOT-23-3 footprint and can be cross-referenced for supply flexibility.

Frequently asked questions

What is the equivalent or replacement for BAT54B5000?

The BAT54B5000 is part of the BAT54 series. Pin-compatible alternatives within the same SOT-23-3 footprint include the BAT54 (single diode), BAT54A (common anode), BAT54C (common cathode), and BAT54S (series pair). Any of these can serve as a functional replacement depending on the circuit configuration.

Can BAT54B5000 be used for high-speed switching?

Yes. The 5 ns reverse recovery time and low junction capacitance (10 pF at 1 V) make it suitable for high-speed switching applications such as DC-DC converter freewheeling diodes, signal clamping, and polarity protection in circuits up to 30 V and 200 mA.
