RN4985FE
TOSHIBA Transistor Silicon NPN · PNP Epitaxial Type
(PCT Process) (Bias Resistor Built-in Transistor)
RN4985FE
Switching, Inverter Circuit, Interface Circuit and
Driver Circuit Applications
•
•
Two devices are incorporated into an Extreme-Super-Mini (6 pin)
package.
Incorporating a bias resistor into a transistor reduces parts count.
Reducing the parts count enables the manufacture of ever more
compact equipment and lowers 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).
