Product details

Its 30 ns reverse recovery time places it in the fast-recovery class (≤500 ns, >200 mA), making it suitable for continuous-conduction-mode PFC boost stages, output rectification in flyback converters, and snubber clamping where switching losses matter.

Conduction loss and thermal budget

Forward voltage is 990 mV maximum at 8 A, which sets the per-diode conduction loss at roughly 7.9 W at full rated current.

Package and mounting — D2PAK field reality

The TO-263-3 (D2PAK) surface-mount package has two leads plus the tab. The tab is the cathode connection for both diodes in the common-cathode pair, so the PCB pad must handle both the thermal and electrical connection. No lab bench needed for the swap — a hot-air station with a D2PAK nozzle and a preheat plate gets it done on site, but the tab solder joint needs a good thermal soak to avoid a cold joint.

Frequently asked questions

Is the STPR1620CG-TR obsolete and what is the replacement?

Yes, the STPR1620CG-TR is listed as obsolete. A pin-compatible replacement would need to match the D2PAK footprint, 200 V reverse voltage, 8 A per diode, common-cathode configuration, and 30 ns or faster reverse recovery time — a parametric search across fast-recovery diodes in D2PAK is the practical path to find a cross.

What is the reverse recovery time of the STPR1620CG-TR?

The reverse recovery time (trr) is 30 ns, which qualifies it as a fast-recovery diode (≤500 ns, >200 mA Io). This 30 ns trr is the key spec for switching applications — it determines the turn-off loss in a hard-switched converter and sets the upper bound on switching frequency before efficiency drops off.
