MBT3904DW1T1G

onsemi · Bipolar (BJT) · SOT-363

MBT3904DW1T1G from onsemi, in a SOT-363. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Emitter 2 passive Emitter of transistor Q2 in dual-transistor package; common return path for collector current with maximum emitter-base voltage rating VEBO = 6.0 Vdc.
2 Base 2 input Base input of transistor Q2; controls collector current through base current in general-purpose NPN amplifier configuration.
3 Collector 1 output Collector output of transistor Q1; maximum continuous current IC = 200 mA with collector-emitter voltage rating VCEO = 40 Vdc.
4 Emitter 1 passive Emitter of transistor Q1 in dual-transistor package; common return path for collector current with maximum emitter-base voltage rating VEBO = 6.0 Vdc.
5 Base 1 input Base input of transistor Q1; controls collector current through base current in general-purpose NPN amplifier configuration.
6 Collector 2 output Collector output of transistor Q2; maximum continuous current IC = 200 mA with collector-emitter voltage rating VCEO = 40 Vdc.
