Product details

The BYV52-200 is a fast-recovery epitaxial diode pair in a common-cathode configuration, housed in a TO-218-3 (SOT-93) through-hole package. The 50 ns reverse recovery time places it in the fast-recovery class, suitable for switching power supplies, freewheeling diodes in motor drives, and snubber circuits where recovery losses matter.

This part is listed as obsolete by the manufacturer.

Common-cathode pair in a TO-218 — board-level fit

The two diodes share a common cathode on pin 2 (tab), with the anodes on pins 1 and 3. This layout is standard for center-tapped rectifier stages and dual-switch clamp networks. The TO-218-3 (SOT-93) through-hole package is a larger plastic power package — expect a 10.2 mm body width and a mounting hole for a screw or clip to a heatsink.

Frequently asked questions

Is BYV52-200 obsolete or still available?

Yes, BYV52-200 is listed as obsolete. It is no longer in production, but available through independent surplus and broker channels. No official replacement is listed.

What is a direct replacement for BYV52-200?

No official direct replacement is listed by the manufacturer. A functionally similar fast-recovery diode pair in a TO-218 package with 30 A per diode and 200 V rating would be the closest parametric match, but pinout and thermal performance must be verified against the original design.
