SWITCHMODE SERIES
NPN SILICON POWER TRANSISTORS
The 2N6544 and 2N6545 transistors are designed for high-
voltage .high-speed, power switching inductive circuits where fall
time is critical.they are particularly, suited for 115 and 220 volt line
operated switch-mode applications such as:
* Switching Regulators
* PWM inverters and Motor Controls
* Solenoid and Relay Drivers
* Deflection Circuits
Specification Features-
High Temperature Performance Specified for: Reversed Biased SQA
with inductive loads Switching Times with Inductive Loads Saturation
Voltages, Leakage Currents.
