RN1544
RN1544 is Silicon NPN Epitaxial Type Transistors manufactured by Toshiba.
TOSHIBA Transistor Silicon NPN Epitaxial Type (PCT process) (Bias Resistor built-in Transistor)
For use in Muting and Switching Applications
- Emitter-base voltage is high: VEBO = 25 V (max)
- Incorporating a bias resistor into a transistor reduces parts count.
Reducing the parts count enable the manufacture of ever more pact equipment and save assembly cost.
