Product details

105 ns trr — the switching parameter that sets the application

1200 V blocking and 15 A forward — thermal and voltage headroom

The 1200 V reverse voltage rating and 15 A average forward current are specified at case temperature. Junction temperature is rated to 175°C.

DO-247 through-hole — mounting and thermal path

The DO-247 package with straight leads is a through-hole format common in high-power rectifier and PFC assemblies. The metal tab is the cathode connection and the primary thermal path.

Frequently asked questions

What is the reverse recovery time (trr) of the STTH1512W?

The reverse recovery time is 105 ns, measured at standard test conditions for fast recovery diodes. This trr makes it suitable for switching frequencies in the tens of kilohertz range where turn-off losses matter.
