Preliminary specification

NPN/PNP resistor-equipped transistors;

R1 = 22 k

Ω, R2 = 22 kΩ

PEMD2

FEATURES

• 300 mW total power dissipation

• Very small 1.6 mm x 1.2 mm ultra thin package

• Self alignment during soldering due to straight leads

• Replaces two SC-75/SC-89 packaged transistors on

same PCB area

• Reduces required PCB area

• Reduced pick and place costs.

APPLICATIONS

• General purpose switching and amplification

• Inverter and interface circuits

• Circuit driver.

DESCRIPTION
