Product details

30 ns reverse recovery — what it buys the switching stage

Its 30 ns reverse recovery time places it in the ultrafast class, suited for continuous-conduction-mode boost PFC stages, output rectification in flyback converters, and snubber clamping where the recovery charge must stay low to limit ringing.

Conduction loss and thermal budget at 3 A

Forward voltage is 1.1 V maximum at 3 A per diode, which sets the conduction loss at 3.3 W per die at rated current.

Reverse leakage and blocking stability

Reverse leakage is 3 µA at the full 200 V blocking voltage — a low figure that confirms the planar-epitaxial die construction. Leakage doubles roughly every 10°C above 25°C, so at 125°C junction the leakage stays under 50 µA, well within the margin of a typical PFC controller's overvoltage protection threshold.

Through-hole TO-220-3 package with the common-cathode pinout: the centre pin is the cathode common, the outer pins are the two anodes. The tab is electrically common with the centre pin, so the heatsink pad must be isolated or the heatsink itself must float. The 0.100-inch pitch is standard for TO-220 footprints.

ROHS3 compliant.

Frequently asked questions

What is the reverse recovery time of STTH602CT?

The reverse recovery time (trr) is 30 ns, measured under standard test conditions. This places it in the ultrafast recovery class, suitable for switching frequencies above 50 kHz in continuous-conduction-mode PFC stages.

What is the maximum current rating of STTH602CT?

The average rectified current is 3 A per diode at the rated forward voltage. The dual-diode package can deliver a total of 6 A when both diodes conduct simultaneously, limited by the TO-220 package thermal capability.

Is STTH602CT RoHS compliant?

Yes, it is ROHS3 compliant, meaning it meets the latest EU RoHS directive with no exemptions for lead, mercury, cadmium, or the four phthalates.
