CBI · Digital Transistors · SOT-363

MMUN5216DW from CBI, 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 E2 passive Emitter of the transistor drawn as Q2 in the schematic; connects to the ground side of the bias network, with Vceo and Vcbo rated 50 Vdc and Ic 100 mAdc max.
2 B2 input Base input of the transistor drawn as Q2, through the integrated 4.7 kOhm series resistor R1 (3.3 to 6.1 kOhm) with no base-emitter resistor R2 (infinite) for MMUN5216DW.
3 C1 passive Collector of the transistor drawn as Q1; rated 50 Vdc Vceo and 100 mAdc Ic max, with VCEsat 0.25 V max at Ic 10 mA, Ib 1 mA.
4 E1 passive Emitter of the transistor drawn as Q1; connects to the ground side of its bias network, with Ic 100 mAdc max.
5 B1 input Base input of the transistor drawn as Q1, through the integrated 4.7 kOhm series resistor R1 (3.3 to 6.1 kOhm) with no base-emitter resistor R2 for MMUN5216DW.
6 C2 passive Collector of the transistor drawn as Q2; rated 50 Vdc Vceo and 100 mAdc Ic max, with VCEsat 0.25 V max at Ic 10 mA, Ib 1 mA.
