Product details

A fast-recovery dual diode that's now in the broker channel

With a 26 ns reverse recovery time, this diode keeps the switching node clean in a 100 kHz+ PFC or LLC converter. The fast recovery cuts the reverse-current spike that would otherwise add turn-on loss in the MOSFET and radiate noise. At 200 V Vr and 10 A If, the forward drop sits at 1.1 V typical — about what you'd expect from a 200 V silicon fast-recovery diode in this current class. The 6 µA reverse leakage at 200 V is low enough that it won't skew a standby power budget.

ST lists the STTH1602CG as obsolete. If you're qualifying a replacement, look for a 200 V, 10 A dual common-cathode fast-recovery diode in D2PAK with a trr at or below 26 ns — several vendors offer pin-compatible parts in the same TO-263-3 footprint. For a production BOM that can't tolerate a single-source risk, this is the point to dual-source or migrate to a current-production equivalent.

Frequently asked questions

What is the direct replacement for STTH1602CG?

ST does not list a direct factory replacement for the STTH1602CG. A functional equivalent would be any 200 V, 10 A dual common-cathode fast-recovery diode in D2PAK with a trr of 26 ns or faster. Parts from ST's own STTH family in the same package may fit, but verify the trr and Vf match your switching frequency and thermal budget.

Is STTH1602CG RoHS compliant?

The evidence does not list a RoHS compliance status for this order code. Verify with the supplier at quote time whether the available stock meets your RoHS requirements.
