LMUN5311DW1T1G

LRC · Digital Transistors · SOT-363

LMUN5311DW1T1G from LRC, in a SOT-363. 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 EMITTER 2 passive Emitter of transistor Q2 (NPN) in the dual BRT; the device is rated for VCEO 50 Vdc and collector current 100 mAdc.
2 BASE 2 passive Base of transistor Q2 (NPN), which drives the integrated bias network (R1 = 10 kΩ series base resistor and R2 = 10 kΩ base-emitter resistor for LMUN5311DW1T1G).
3 COLLECTOR 1 passive Collector of transistor Q1 (PNP) in the dual BRT; the device is rated for VCBO 50 Vdc and collector current 100 mAdc.
4 EMITTER 1 passive Emitter of transistor Q1 (PNP) in the dual BRT, with the same 50 V and 100 mA ratings as the device.
5 BASE 1 passive Base of transistor Q1 (PNP), which drives the integrated bias network (R1 = 10 kΩ series base resistor and R2 = 10 kΩ base-emitter resistor for LMUN5311DW1T1G).
6 COLLECTOR 2 passive Collector of transistor Q2 (NPN) in the dual BRT; the device is rated for VCBO 50 Vdc and collector current 100 mAdc.
