Product details

20 ns reverse recovery — fast-switching rectifier in DPAK

Its 20 ns reverse recovery time places it in the ultrafast class, suited for continuous-conduction-mode power supplies and high-frequency rectification where switching losses dominate the thermal budget.

4 A per diode, 1.1 Vf — conduction loss in a dual package

Each diode in the common-cathode pair delivers 4 A average with a maximum forward voltage of 1.1 V at that current. Reverse leakage is specified at 4 µA at 200 V, a figure that rises with junction temperature. The maximum junction temperature is 175°C, which gives headroom for high-ambient designs if the thermal pad is properly managed.

STMicroelectronics lists the STTH802CB as obsolete.

Frequently asked questions

What is the replacement for STTH802CB?

No official replacement part number is recorded for the STTH802CB. For a pin-compatible alternative in the same 200 V, 4 A, fast-recovery class, compare parametric specs against current STTH series dual diodes in DPAK — the 20 ns trr and common-cathode configuration are the key matching criteria.

What package does the STTH802CB come in?

It is supplied in a TO-252-3 DPAK surface-mount package, also referred to as SC-63. The two leads plus exposed tab are soldered to the board; the tab carries the cathode connection and must be connected to the thermal pad.
