DTA124XE3TL

Overview

The DTA124XE3TL is a PNP digital transistor from the Rohm Semiconductor DTA124X series, featuring built-in biasing resistors. It operates with a supply voltage of -50V and a maximum collector current of -100mA. The internal resistor configuration consists of R1 at 22kΩ and R2 at 47kΩ. Key electrical characteristics include a DC current gain (GI) of 68 minimum at -5mA output, a transition frequency of 250MHz, and a power dissipation rating of 150mW. The device is housed in an EMT3 (SOT-416) surface-mount package.

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 high-speed switching capability suitable for interface and driver applications.

Applications

• Inverter circuits
• Interface logic
• Driver stages

Procurement Notes

Verify the specific suffix 'E3' to confirm the SOT-416 (EMT3) package variant. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure storage conditions adhere to humidity barrier bag requirements to maintain solderability.

Selection Notes

Select this component when a compact PNP digital solution with integrated biasing is required. The 22kΩ/47kΩ resistor ratio supports standard logic interfacing. Verify that the 150mW power dissipation limit accommodates the thermal environment of the target application.

Part Context

This part belongs to the DTA124X series of bias resistor built-in transistors. It serves as the PNP counterpart to the DTC124X NPN series. The E3 designation specifically identifies the SOT-416 package form factor within the broader product family.

Replacement Considerations

DTA124XM: Same electrical specifications but utilizes a SOT-723 package. DTA124XEB: Identical performance metrics packaged in SOT-416FL. Verify pinout compatibility and physical footprint differences before substitution.
