Product details

The BYW100-200 is a standard fast-recovery rectifier diode from WeEn Semiconductor, rated for 200 V reverse voltage and 1.5 A average forward current. The 1.2 V forward drop at 4.5 A pulsed current gives a reasonable efficiency trade-off for that speed.

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.

Frequently asked questions

What is the replacement for BYW100-200?

A replacement must be a fast-recovery rectifier rated for at least 200 V reverse voltage, 1.5 A average forward current, and a reverse recovery time of 35 ns or faster in a DO-15 axial package. Validate any candidate against these three parameters before substituting.

What is the reverse recovery time (trr) of BYW100-200?

The reverse recovery time is 35 ns, which qualifies it as a fast-recovery diode (≤500 ns) suitable for switching power supplies operating in the tens to low hundreds of kilohertz.
