SDTA114YET1G

Overview

The SDTA114YET1G is a single PNP Bias Resistor Transistor (BRT) from onsemi, housed in an SC-75 package. It integrates a monolithic bias network consisting of a series base resistor and a base-emitter resistor to replace discrete components. Key electrical ratings include a maximum collector-emitter voltage of 50 Vdc and continuous collector current of 100 mAdc. The device features a typical input resistance of 10 kOhms with a resistor ratio of 0.21. Thermal characteristics specify a total power dissipation of 200 mW at 25°C, operating within a junction temperature range of -55°C to +150°C.

Feature Summary

• Integrates a single transistor with a monolithic bias network comprising two resistors to eliminate external biasing components.
• Designed to simplify circuit design by reducing board space and component count.
• Qualified for automotive applications under AEC-Q101 standards with PPAP capability.

Applications

• Automotive systems requiring unique site and control change requirements.
• General-purpose digital switching circuits replacing discrete transistor-resistor networks.
• Interface and driver applications where simplified biasing is required.

Procurement Notes

Verify the specific ordering suffix 'ET1G' corresponds to the SC-75 package and tape & reel shipping configuration as listed in the official onsemi ordering information table. Confirm that the S prefix indicates compliance with automotive site and control change requirements if such specifications are necessary for the target application. Ensure RoHS and halogen-free status aligns with project environmental constraints.

Selection Notes

Select this component when a compact PNP solution with integrated biasing is needed to reduce assembly complexity. The SC-75 package offers a balance between thermal performance and footprint size compared to smaller packages like SOT-23. Consider the 50V voltage rating and 100mA current capacity to ensure adequate headroom for the intended load conditions.

Part Context

This part belongs to the DTA114YE series of digital transistors manufactured by onsemi. It shares the same internal circuit topology and electrical characteristics as other variants in the family, differing primarily in packaging and shipping options. The series is designed to provide a direct replacement for discrete BJT and resistor combinations in various electronic designs.

Replacement Considerations

Direct pin-compatible substitutes within the same family include DTA114YET1G. Other package variants such as DTA114YM3T5G (SOT-723) offer different thermal and spatial characteristics but maintain identical electrical functionality. Verify package dimensions and marking codes when substituting across different form factors.
