Product details

Schottky pair with common anode — what the 5 ns trr means

The 5 ns reverse recovery time is the headline switching spec — Schottky diodes store negligible charge, so this part transitions from forward to blocking state fast enough for high-frequency rectification, clamping, and flyback catch-diode duty in DC-DC converters switching at hundreds of kilohertz. The 30 V reverse voltage and 800 mV forward drop at 100 mA are typical for this Schottky family, trading a slightly higher Vf than a 20 V variant for more headroom on 12 V and 24 V rails.

Infineon lists the part as Obsolete.

Frequently asked questions

Is BAT 54-06 B5003 obsolete?

There is no official replacement part number from Infineon. Sourcing is through independent distribution for new-old-stock or verified surplus inventory.

What is the difference between BAT54-06 and BAT54?

The BAT54 is a single Schottky diode in SOT-23, while the BAT 54-06 is a dual diode in a common-anode configuration — two anodes with a shared cathode. The BAT 54-06 B5003 variant carries the same 30 V / 200 mA per-diode ratings as the single BAT54 but in a three-pin package that replaces two discrete diodes with one component.
