NPN/PNP resistor-equipped transistors
Product specification
PUMD12
FEATURES
• Transistors with different polarity and built-in bias resistors – TR1 (NPN): R1 = R2 = 47 kΩ – TR2 (PNP): R1 = R2 = 47 kΩ
• No mutual interference between the transistors
• Simplification of circuit design • Reduces number of components
and board space.
APPLICATIONS
• Especially suitable for space reduction in interface and driver circuits
• Inverter circuit configurations without use of external resistors.
DESCRIPTION
NPN/PNP resistor-equipped transistors in an SC-88 (SOT363) plastic package.
