Product details

40 ns fast recovery in a TO-220AC power package

Packaged in the through-hole TO-220AC case, it is designed for output rectification, freewheeling, and snubber clamping in switched-mode power supplies, PFC stages, and DC-DC converters where reverse-recovery losses must be minimized.

Obsolete — sourcing via surplus and broker channels

No last-time-buy window remains open through the factory. Procurement for this order code now depends on surplus inventory held by independent distributors and brokers. Buyers should verify date-code freshness and packaging condition — sealed factory reels with consistent date-codes are preferred over mixed-date auction lots.

Forward drop and thermal budget at 20 A

At the full 20 A rated current the forward voltage is 1.1 V, producing a conduction loss of 22 W. The 10 µA reverse leakage at 200 V is a room-temperature typical; leakage doubles roughly every 10 °C rise, so at elevated junction temperatures the leakage contribution to standby loss should be checked against the application's idle budget.

Frequently asked questions

Is STTH2002D obsolete?

Yes, the STTH2002D carries an Obsolete lifecycle status. STMicroelectronics has permanently discontinued production, and no last-time-buy window remains open. The part is available only through surplus and independent broker channels.

What is the equivalent or replacement for STTH2002D?

A pin-compatible replacement would need to match the TO-220AC package, 200 V reverse voltage, 20 A current rating, and 40 ns reverse recovery time. Candidates from the same fast-recovery family include the STTH2002 series base number, but each variant should be verified for exact parametric match and package compatibility before substitution.
