Two independent 100 A diodes share the common cathode ISOTOP footprint, each rated for 200 V reverse voltage with an 80 ns reverse recovery time. Forward voltage is 850 mV at the full 100 A rated current. The part is a standard-technology fast-recovery diode suited for high-current rectification, freewheeling, and snubber circuits in power supplies, motor drives, and welding equipment where the 80 ns trr keeps switching losses low. ## Obsolete — no official replacement listed An RFQ will confirm current availability and pricing; date codes and screening options (e.g., tape/reel vs tube) can be specified at quote time. The 80 ns reverse recovery time places the BYV255V-200 in the fast-recovery class (≤500 ns per the speed code). For a 100 A diode at 200 V, 80 ns trr means the diode clears stored charge quickly enough for 20–50 kHz hard-switched converters without excessive turn-off loss or ringing. Compare this to a standard 200 V 100 A rectifier with trr in the microsecond range — the BYV255V-200 cuts recovery losses by roughly an order of magnitude. The 100 µA reverse leakage at 200 V is typical for a fast-recovery die of this current class; expect it to rise with junction temperature, but the 150°C maximum junction rating gives thermal headroom for forced-air or liquid-cooled heatsinks.","metaTitle":"STMicroelectronics BYV255V-200 Fast Recovery Diode","metaDescription":"STMicroelectronics BYV255V-200 dual fast-recovery diode, 200V 100A per diode, 80ns trr, ISOTOP chassis-mount.
