In a common-cathode pair, both diodes share the same cathode tab, so the total heat dissipated through the TO-220FP backplate is the sum of both channels. ## Reverse leakage and blocking voltage Maximum reverse leakage is 400 µA at 45 V. Schottky leakage rises exponentially with junction temperature, so at high ambient or heavy load the leakage contribution to the thermal budget becomes non-negligible. The 45 V blocking rating is the absolute maximum — derate for reliable operation in a 24 V or 36 V rail, but do not push it above 40 V continuous if you want margin against transients. ## Switching speed and application fit Listed as a fast recovery diode with recovery time ≤ 500 ns at > 200 mA. For a Schottky, this is a conservative classification — the majority carrier structure inherently switches faster than a PN junction. Through-hole TO-220-3 Full Pack (TO-220FP). The three leads are the two anodes and the common cathode tab. The full-pack body is fully molded — no exposed metal — so the mounting screw does not require an insulating bushing.

The cathode is the metal tab (pin 2 in TO-220FP), and the two anodes are pins 1 and 3. This configuration is typical for center-tapped secondary rectification or dual-output rectifiers where the cathodes tie to the same output rail."},{"question":"What is the difference between STPS30L45CFP and STPS30L45CT?","answer":"The STPS30L45CT uses a standard TO-220 package with an exposed metal tab that requires an insulating pad or thermal washer when mounting to a grounded heatsink. The STPS30L45CFP uses the TO-220FP full-pack (fully isolated) package — the tab is electrically isolated, so no insulating hardware is needed.
