Product details

This is a Schottky rectifier rated for 200 V reverse voltage and 10 A average forward current per diode in a common-cathode pair. The 860 mV forward voltage drop at 10 A is typical for a 200 V Schottky at this current — expect a trade-off between blocking voltage and Vf. The 15 µA reverse leakage at 200 V is a static loss contributor at high line; in a hot junction the leakage climbs, so derate the thermal design accordingly. The fast recovery spec (≤500 ns, >200 mA) is typical for a Schottky — no stored charge, so switching losses are low.

Housed in a TO-220-3 through-hole package with narrow leads (TO-220AB). The common-cathode configuration means the center tab is the shared cathode — heatsink mounting requires electrical isolation unless the heatsink is grounded to the cathode potential. Through-hole assembly suits manual or wave-solder rework; no moisture sensitivity level is stated, but standard TO-220 handling applies.

Frequently asked questions

What is the replacement for STPS20200CTN?

For a pin-compatible substitute, look for a TO-220-3 common-cathode Schottky with 200 V reverse voltage and 10 A per diode rating. The STPS20150CT is a lower-voltage (150 V) sibling but does not match the 200 V requirement.

What is the difference between STPS20200CTN and STPS20150CT?

The primary difference is reverse voltage rating: STPS20200CTN is rated for 200 V, while STPS20150CT is rated for 150 V. Both are common-cathode Schottky rectifiers in TO-220-3 packages with similar forward voltage and current specs. The 200 V part suits higher-voltage rails or applications needing more voltage margin.
