BCR420UW6Q-7

Diodes Incorporated · LED Drivers · SOT-26

BCR420UW6Q-7 from Diodes Incorporated, in a SOT-26. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 EN input Enable for biasing the transistor; VEN max 40V on BCR420U and 18V on BCR421U, typical enable current 1.2mA, and the BCR421U EN can be PWM dimmed up to 25kHz.
2 OUT passive Regulated output current sink for the LED string, with VOUT up to 40V and IOUT up to 500mA absolute maximum.
3 OUT passive Regulated output current sink for the LED string, with VOUT up to 40V and IOUT up to 500mA absolute maximum.
4 GND power_in Power ground, reference for all voltage ratings.
5 OUT passive Regulated output current sink for the LED string, with VOUT up to 40V and IOUT up to 500mA absolute maximum.
6 REXT passive Optional external resistor for adjusting the output current from the 10mA preset up to 350mA, in parallel with the internal 95Ω resistor.
