The 1.2 V forward drop at 4.5 A pulsed current gives a reasonable efficiency trade-off for that speed. ## Obsolete — plan your BOM move now ## DO-15 axial package — board-level fit The diode comes in a DO-204AC (DO-15) axial-lead through-hole package, which is a common footprint for 1 A–2 A rectifiers. The through-hole mounting suits point-to-point wiring, terminal blocks, or boards where wave-solder assembly is the standard. ## Reverse leakage and junction temperature Maximum reverse leakage is 10 µA at the rated 200 V, which is typical for a fast-recovery silicon diode at room temperature.","metaTitle":"BYW100-200 Fast Recovery Rectifier, 200V 1.5A 35ns trr","metaDescription":"BYW100-200 is a 200V 1.5A fast recovery rectifier with 35ns trr in DO-15 axial package.
