Product details

Dual 60 A fast recovery diodes in ISOTOP

The STTH120L04TV1 integrates two independent fast recovery diodes in a single ISOTOP chassis-mount package. Each diode is rated for 60 A average rectified current at a 400 V reverse voltage, with a 90 ns reverse recovery time. The 90 ns trr places this in the fast-recovery class (≤500 ns, >200 mA Io), suitable for high-frequency rectification and snubber circuits where switching losses matter. The forward drop is 1.2 V maximum at 60 A per diode.

ISOTOP package and thermal design

The ISOTOP (ISOTOP®) package is a chassis-mount module designed for bolting directly to a heatsink or cold plate. Maximum junction temperature is 150°C. Reverse leakage at 400 V is 50 µA, typical at 25°C — this rises with junction temperature and should be factored into the thermal budget at high load.

Frequently asked questions

Is the STTH120L04TV1 obsolete?

Yes, the STTH120L04TV1 carries an Obsolete product status from STMicroelectronics. No official successor or replacement part is listed.

Is the STTH120L04TV1 a dual common cathode diode?

No. The diode configuration is 2 Independent, not common cathode. Each diode has its own anode and cathode terminals, allowing independent circuit placement.
