UMC5N-7

Diodes Incorporated · Digital Transistors · SOT-353

UMC5N-7 from Diodes Incorporated, in a SOT-353. 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 C1 passive Collector of NPN transistor Q1. Absolute max VCC = 50 V, IC(MAX) = 100 mA; typical output current 30 mA.
2 B2 input Base input of PNP transistor Q2 through built-in series resistor R1 = 4.7 kΩ (3.29-6.11 kΩ). VI(ON) ≤ −2.5 V drives Q2 into saturation; VI(OFF) ≥ −0.3 V keeps Q2 off. Absolute max VIN = −20 V to +7 V.
3 B1 input Base input of NPN transistor Q1 through built-in series resistor R1 = 47 kΩ (32.9-61.1 kΩ). VI(ON) ≥ 3 V drives Q1 into saturation; VI(OFF) ≤ 0.5 V keeps Q1 off. Absolute max VIN = −10 V to +40 V.
4 C2 passive Collector of PNP transistor Q2. Absolute max VCC = −50 V, IC(MAX) = −100 mA; typical output current −100 mA.
5 E1/E2 passive Common emitter - internally tied emitter of NPN Q1 and PNP Q2. Typically returned to the ground or supply rail depending on the switching topology.
