SQD400AA120

TRANSISTOR MODULE

UL;E76102

（M）

Thermal Impedance

(junction to case)

SQD400AA120 is a Darlington power transistor module with a high speed, high power

Darlington transistor. The transistor has a reverse paralleled fast recovery diode. The

mounting base of the module is electrically isolated from Semiconductor elements for

simple heatsink construction.

●

●

Low saturation voltage for higher efficiency

●

High DC current gain.

●

Isolated monuting base
