Product details

The STMicroelectronics BYW80FP-200 is a standard fast-recovery diode rated for 200 V reverse voltage and 10 A average rectified current. The TO-220FPAC full-pack (fully isolated) package eliminates the need for an insulating washer, simplifying assembly and improving thermal repeatability on a single-sided heatsink.

What the 200 V / 10 A rating means for your BOM

The 200 V reverse voltage provides a comfortable derating margin on a 110/220 VAC input PFC boost stage (bus voltage typically 400 VDC — in that application a 600 V diode is needed, not this part). The 10 A average forward current suits continuous conduction mode rectifiers in the 150–300 W output range. Forward voltage is 1.15 V at 15 A, so thermal design should budget roughly 11.5 W peak dissipation; the full-pack junction-to-case thermal path relies on good contact to a heatsink. Reverse leakage is rated 10 µA at 200 V, fine for most industrial environments, but the junction temperature maxes at 150 °C — derate current above 100 °C case temperature.

Frequently asked questions

Is BYW80FP-200 obsolete?

Yes, STMicroelectronics lists the BYW80FP-200 as Obsolete. No official replacement order code is published.

What is the replacement for BYW80FP-200?

No official successor is listed. For a new design, evaluate current-production 10 A / 200 V fast-recovery diodes in the TO-220FPAC (full-pack) package from ST or other vendors; the footprint is standard but pinout and thermal specs should be verified against the BYW80FP-200.

What are the specifications of BYW80FP-200?

It is a 200 V, 10 A fast-recovery diode with a 35 ns reverse recovery time, 1.15 V forward drop at 15 A, 10 µA reverse leakage at 200 V, and a 150 °C maximum junction temperature. Package is the TO-220FPAC (full-pack, through hole).
