Product details

40 ns trr — the switching edge this diode brings

The STTH8BC060D is a 600 V, 8 A fast recovery diode from STMicroelectronics, built for the boost and PFC stages of switch-mode power supplies. Its 40 ns reverse recovery time (trr) is the key parameter — it cuts the switching losses in continuous-conduction-mode PFC and lets the designer push the switching frequency higher without cooking the diode.

STMicroelectronics lists the STTH8BC060D as Obsolete.

Ratings that set the application envelope

600 V reverse voltage and 8 A average rectified current place this diode squarely in the 300–400 W PFC stage or output rectification of a 150–250 W flyback converter. The 3.6 V forward drop at 8 A is on the higher side for a fast diode — expect conduction loss to be a factor in the thermal budget, especially in a TO-220AC package without a heatsink.

Frequently asked questions

What is the replacement for STTH8BC060D?

STMicroelectronics has not published an official replacement or cross-reference for the STTH8BC060D. A designer evaluating a substitute should look at current-production 600 V, 8 A fast-recovery diodes in TO-220AC from ST or other vendors, paying close attention to trr, Vf, and package pinout.

What is the reverse recovery time of STTH8BC060D?

The reverse recovery time (trr) is 40 ns, which qualifies it as a fast recovery diode (≤ 500 ns at > 200 mA Io). This trr enables low switching losses in high-frequency PFC and SMPS topologies.
