BCR402UW6-7

Diodes Incorporated · LED Drivers · SOT-26

BCR402UW6-7 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 GND power_in Power ground; GND (enable) current is 340 to 500 µA at VS = 10V with VOUT open.
2 OUT passive Regulated output current to the LED string, 20mA nominal (18 to 22mA) and 100mA absolute maximum; tied internally with the other OUT pins and used as the heat-sinking lead.
3 OUT passive Regulated output current to the LED string, 20mA nominal (18 to 22mA) and 100mA absolute maximum; tied internally with the other OUT pins and used as the heat-sinking lead.
4 VS power_in Supply voltage input, 40V absolute maximum, with at least 1.4V headroom above VOUT for regulation.
5 OUT passive Regulated output current to the LED string, 20mA nominal (18 to 22mA) and 100mA absolute maximum; tied internally with the other OUT pins and used as the heat-sinking lead.
6 Rext passive Optional external resistor connection that adjusts output current above the 20mA preset, up to 100mA, in parallel with the 44Ω internal resistor.
