Fast recovery diode in an isolated full-pack — what the 30 ns trr means
Its 30 ns reverse recovery time places it in the ultrafast class, suited for switching power supplies, freewheeling diodes in motor drives, and snubber circuits where recovery losses matter.
Obsolete — plan the last buy or cross now
STMicroelectronics lists the STTH602CFP as obsolete. No last-time-buy window or successor part number is recorded in the official lifecycle data. For a BOM that still calls out this exact order code, the practical path is independent-distribution sourcing against an RFQ — stock is out there on the spot market, but the window to buy at reasonable pricing narrows as inventory ages.
175°C junction — where it runs
The forward voltage drop of 1.1 V at 3 A per diode is typical for a 200 V fast-recovery part in this current class; the 3 µA reverse leakage at rated voltage is low enough that self-heating from leakage is negligible in normal operation.
Package and mounting — TO-220FP through-hole
Through-hole TO-220-3 Full Pack, also called TO-220FP. The three leads are standard 0.1-inch pitch, and the full plastic encapsulation means the back of the package is electrically isolated — no need for a mica washer or silicone pad when bolting to a heatsink. The tube shipping medium is fine for hand-assembly or low-volume production; for automated insertion you would want the tape-and-reel variant if one exists in the family. Store the reels dry if you buy a last-time-batch; the package is not moisture-sensitive by default, but the leads can oxidize over long shelf storage.
