Product details

Its 25 ns reverse recovery time (trr) keeps switching losses low in hard-switched topologies like power-factor-correction boost stages and flyback secondary rectification. The 1.1 V forward voltage at 6.5 A is typical for a 200 V-class ultrafast diode — it's a trade-off that favors speed over a lower Vf. With a 175°C maximum junction temperature, the die can handle sustained thermal stress in enclosed power supplies where airflow is minimal.

That means the factory line has shut down and no last-time-buy window remains.

D2PAK package — board-level fit

The part comes in a D2PAK surface-mount package with the standard 2-lead-plus-tab footprint. At 6.5 A per diode with a 25 ns trr, the switching losses are low enough that a properly laid-out D2PAK with adequate copper area can handle the dissipation without forced air in many PFC designs.

Frequently asked questions

Is STTH1302CG-TR obsolete?

Yes, the STTH1302CG-TR is listed as Obsolete by STMicroelectronics. It must be sourced from the surplus market.

What is the STTH1302CG-TR reverse recovery time?

The reverse recovery time (trr) is 25 ns, making it a fast-recovery diode suitable for switching frequencies where low turn-off losses matter.
