60 A, 600 V fast recovery diode in DO-247
The STTH60RQ06W is a 60 A, 600 V standard fast recovery diode from STMicroelectronics, housed in a through-hole DO-247 package. It is classified as a fast recovery type with a reverse recovery time (trr) of 65 ns, placing it in the < 500 ns, > 200 mA category.
Ratings that define the switching and thermal budget
Averaging 60 A of forward current at 600 V reverse voltage, this diode suits high-current boost or flyback stages in power supplies and inverters. The 65 ns reverse recovery time means the diode clears stored charge quickly, reducing turn-off losses in hard-switched topologies like PFC or output rectification. Reverse leakage is 80 µA at the full 600 V blocking voltage and 25 °C junction — a low figure that keeps standby dissipation under control. The maximum junction temperature of 175 °C gives headroom for thermal cycling in confined enclosures, provided the heatsink keeps the case temperature within the SOA.
Package and board integration
The DO-247-2 (straight leads) package is a through-hole, two-lead power package with a large copper tab for heatsink mounting. The tab is the cathode; the anode is the opposite lead. The package footprint is standard for the DO-247 outline, so existing PCB layouts for similar 60 A diodes accept this part with no board spin.
