RN1544
TOSHIBA Transistor Silicon NPN Epitaxial Type (PCT process) (Bias Resistor built-in Transistor)
RN1544
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
compact equipment and save assembly cost.

Note: Using continuously under heavy loads (e.g. the application of high
temperature/current/voltage and the significant change in temperature, etc.)
may cause this product to decrease in the reliability significantly even if the
operating conditions (i.e. operating temperature/current/voltage, etc.) are
within the absolute maximum ratings.
Please design the appropriate reliability upon reviewing the Toshiba
Semiconductor Reliability Handbook (“Handling Precautions”/“Derating
Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
