Overview
The DTC123YE3TL is an NPN digital transistor from the ROHM DTC123Y series, housed in a SOT-416 (EMT3) surface-mount package. It integrates biasing resistors R1 and R2 with a single NPN transistor to simplify circuit design. Key electrical parameters include a supply voltage of 50V, a maximum collector current of 100mA, and a power dissipation of 150mW. The typical input resistance R1 is 2.2kΩ, while R2 is 10kΩ, yielding a resistance ratio of 4.5. The device features a transition frequency of 250MHz and a minimum DC current gain of 33.
Feature Summary
