DTC123EE3TL

Overview

The DTC123EE3TL is an NPN digital transistor from the ROHM DTC123E series, housed in a SOT-416 (EMT3) surface-mount package. It integrates biasing resistors with R1 and R2 both at 2.2 kΩ. The device supports a maximum supply voltage of 50 V and a continuous collector current of 100 mA. Key electrical parameters include a minimum DC current gain of 20 at 20 mA output, a transition frequency of 250 MHz, and a power dissipation rating of 150 mW. The component operates within a junction temperature range up to 150°C.

Feature Summary

• Built-in biasing resistors eliminate the need for external input components, simplifying circuit design.
• Enables direct configuration of inverter circuits by setting only on/off conditions.
• Provides complementary PNP types within the DTA123E series.

Applications

• Inverter circuits
• Interface applications
• Driver circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm the exact packaging format and reel specifications. Confirm RoHS compliance status and ensure the component meets the required storage and handling guidelines for electrostatic-sensitive devices before integration into production lines.

Selection Notes

Select this component when a single NPN digital transistor with equal internal biasing resistors is required. Ensure the application voltage does not exceed the 50 V limit and that the thermal environment allows for proper heat dissipation within the 150 mW power rating. Verify compatibility with the SOT-416 footprint during PCB layout.

Part Context

This part belongs to the DTC123E series of bias resistor built-in transistors. It shares functional characteristics with other variants in the family but differs in physical package dimensions and taping codes. The EE3 suffix specifically denotes the SOT-416 package configuration used for surface-mount assembly.

Replacement Considerations

Complementary PNP versions are available in the DTA123E series. Other packages within the same electrical specification family include SOT-723, SOT-323, and SOT-346 variants, provided the mechanical footprint can be adapted.
