KBL400 Thru KBL410 is a silicon bridge rectifier from COMCHIP. It features low forward voltage drop, high reliability, and high current capability.
The KBL400‑410 series are molded‑plastic silicon bridge rectifiers designed for PCB mounting. They offer low forward voltage drop, high current capability, and high surge current capability, making them suitable for a wide range of power‑conversion applications.
The datasheet lists key electrical ratings such as reverse voltage up to 1000 V, forward current of 4 A, and includes mechanical data, thermal resistance, and detailed forward/reverse characteristic curves for each model in the series.
| Reverse Voltage | 50 – 1000 V |
|---|---|
| Forward Current | 4.0 A |
| Case Material | Molded Plastic |
| Weight | 5.6 g (approx.) |
| RMS Reverse Voltage | 35 – 700 V |
| Forward Voltage @ 2 A | 1.1 V |
| Operating Temperature Range | -65 °C to +125 °C |
| Thermal Resistance (junction‑to‑ambient) | 19 K/W |
| Capacitive Load Derating | 20 % reduction of forward current |
Each device is rated for a continuous forward current of 4.0 A.
For capacitive loads, the forward current should be derated by 20 %.
The typical junction‑to‑ambient thermal resistance is 19 K/W.
