Overview
The DTA143TET1G is a Bias Resistor Transistor (BRT) manufactured by onsemi, featuring a single PNP transistor integrated with a monolithic bias resistor network. It operates with a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes built-in resistors: R1 (base) is typically 4.7 kOhms and R2 (emitter) is typically 4.7 kOhms. Packaged in the SOT-723 surface-mount format, it dissipates up to 260 mW. The component supports an operating temperature range from -55°C to +150°C and meets RoHS compliance standards.
Feature Summary
- Integrates a single PNP transistor with a monolithic bias network consisting of series base and base-emitter resistors to eliminate external components.
- Simplifies circuit design by reducing board space and component count while maintaining standard digital switching functionality.
- Utilizes thin-film resistors for complete isolation, allowing negative input biasing and minimizing parasitic effects.
Applications
- Inverter circuits requiring simplified input biasing without external resistors.
- Interface applications between logic families needing level shifting or buffering.
- Driver stages for low-power switching loads where board space is constrained.
Procurement Notes
Verify the specific suffix 'T1G' against the manufacturer's latest datasheet to confirm tape-and-reel packaging quantities and lead times. Ensure the order matches the exact pinout configuration for SOT-723. Cross-reference the RoHS status and material declarations with current environmental compliance reports before finalizing procurement orders.
Selection Notes
Select this component when a PNP BRT with 4.7k/4.7k resistor values is required. Confirm that the 50V VCEO rating suits the application voltage. Verify that the SOT-723 package dimensions fit the PCB layout constraints. Compare hFE minimums and saturation voltages against load requirements to ensure adequate drive capability.
Part Context
This part belongs to the DTA143 series of Bias Resistor Transistors from onsemi. It is functionally similar to other PNP BRTs like the DTA143EM3T5G but may differ in packaging or specific electrical tolerances. The series is designed to replace discrete transistor-resistor combinations in digital switching applications.
Replacement Considerations
Check for direct substitutes such as DTA143EM3T5G or DTA143TM3T5G. Verify pin compatibility and electrical parameter equivalence, particularly VCEO and IC ratings. Ensure the replacement package matches the existing footprint if board rework is not planned.
