Product details

80 V, 10 A common-cathode Schottky in a fully isolated TO-220FPAB

At 10 A forward current the maximum forward voltage is 740 mV, which translates to roughly 7.4 W conduction loss per diode at full rated current. In a 20 A total output design with both diodes conducting alternately, the combined dissipation lands near 15 W. The TO-220FPAB's isolated tab lets you bolt directly to a heatsink without a sil-pad, keeping the thermal resistance lower than a non-isolated TO-220 with an insulator.

For BOM lines that still call out this order code, the supply channel is independent distribution — surplus, new-old-stock, or broker inventory.

Frequently asked questions

Is STPS20M80CFP obsolete?

Yes, the STPS20M80CFP is listed as Obsolete by STMicroelectronics. No official replacement order code is recorded. For new designs, evaluate current ST 80 V Schottky diodes in TO-220FPAB.

What is the replacement for STPS20M80CFP?

No official successor is listed. The STPS20M80CFP is obsolete; for a pin-compatible replacement in the same function, review ST's active 80 V Schottky portfolio in TO-220FPAB — parametric similarity must be verified against your current and voltage requirements.

What are the specifications of STPS20M80CFP?

It is a dual Schottky rectifier, common-cathode configuration, rated 80 V reverse voltage, 10 A average rectified current per diode, 740 mV maximum forward voltage at 10 A, 30 µA reverse leakage at 80 V, 175°C maximum junction temperature, in a TO-220FPAB full-pack through-hole package.

Is STPS20M80CFP RoHS compliant?

The evidence does not explicitly state RoHS compliance status. Verify with the manufacturer's latest documentation or request a certificate of compliance at quote time.
