Overview
The onsemi DTA114YET1 is a PNP Bias Resistor Transistor (BRT) housed in the SC-75/SOT-416 package. It integrates a single transistor with a monolithic bias network consisting of a series base resistor (R1 = 10 kΩ) and a base-emitter resistor (R2 = 47 kΩ). The device supports a maximum collector current of 100 mA and withstands collector-emitter voltages up to 50 Vdc. Key electrical characteristics include a minimum DC current gain (hFE) of 80 at 5 mA and 10 V, a maximum collector-emitter saturation voltage of 250 mV at 10 mA, and a total power dissipation of 200 mW.
Feature Summary
- Integrates a single transistor with a monolithic bias network containing two resistors to replace individual components.
- Reduces board space and component count by eliminating external input resistors for inverter circuit configurations.
- Features modified gull-winged leads in the SC-75/SOT-416 package designed to absorb thermal stress during wave or reflow soldering.
Applications
- Inverter circuits
- Interface applications
- Driver circuits
Procurement Notes
Verify that the specific part number matches the required resistor values (R1=10k, R2=47k) and polarity (PNP). Confirm compliance with automotive qualification standards if the application requires AEC-Q101 certification. Ensure the ordering suffix aligns with the desired packaging format, such as tape and reel quantities specified in the manufacturer's documentation.
Selection Notes
Select this component when a compact solution is needed to simplify circuit design by reducing the bill of materials. The integrated bias network allows for straightforward on/off control without external resistors. Verify that the 100 mA collector current and 50 V breakdown voltage meet the system requirements before implementation.
Part Context
This device belongs to the DTA114EET1 Series, which includes various PNP BRT configurations with different internal resistor ratios. The DTA114YET1 specifically utilizes a 10 kΩ base resistor and a 47 kΩ emitter-base resistor.
