Product specification

NPN/PNP resistor-equipped transistors

PUMD9

FEATURES

• Transistors with different polarity and built-in bias

resistors R1 and R2 (typ. 10 k

Ω and 47 kΩ respectively)

• No mutual interference between the transistors

• Simplification of circuit design

• Reduces number of components and board space.

APPLICATIONS

• Especially suitable for space reduction in portable

equipment

• Inverter circuit configurations without use of external

resistors.
