DTA124XET1G

Overview

The DTA124XET1G is a PNP Bias Resistor Transistor (BRT) manufactured by onsemi, designed to replace discrete transistors and external bias networks. It integrates a single PNP silicon transistor with a monolithic bias network comprising a series base resistor and a base-emitter resistor within an SC-75/SOT-416 package. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device features a typical input resistance of 22 kOhms and a typical resistor ratio of 0.047. It operates within a temperature range of -55°C to +150°C, with a power dissipation rating of 260 mW.

Feature Summary

• Integrates a PNP transistor with a monolithic bias network consisting of two resistors to simplify circuit design.
• Reduces board space and component count by replacing individual devices and external resistor networks.
• Package design allows for wave or reflow soldering, with modified leads absorbing thermal stress during the process.

Applications

• General-purpose switching applications requiring simplified biasing.
• Circuits where board space reduction and component count minimization are critical.
• Digital logic interface circuits utilizing pre-biased transistor configurations.

Procurement Notes

Verify the specific suffix 'ET1' against the manufacturer's official datasheet to confirm the exact packaging configuration and tape-and-reel specifications. Ensure that the SC-75/SOT-416 package outline matches the target PCB footprint requirements. Confirm RoHS compliance status through the latest product change notification documents provided by onsemi before finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required to reduce schematic complexity. Verify that the 50 V voltage rating and 100 mA current capacity meet the load requirements. Consider the SOT-416 package size constraints and ensure compatibility with the intended assembly method, whether wave or reflow soldering, as specified in the mechanical data.

Part Context

This part belongs to the DTA124X family of Bias Resistor Transistors from onsemi. These devices are engineered to streamline the design of switching circuits by combining active and passive components into a single surface-mount package. The family offers various resistor ratios and package options to accommodate different impedance matching and space-saving needs in consumer and industrial electronics.

Replacement Considerations

Compatible substitutes include other PNP BRTs with similar VCEO and Ic ratings, such as the DTA124EET1G from onsemi or equivalent parts from Rohm Semiconductor like the DTA124EETL, provided the pinout and internal resistor values match the original design requirements.
