Overview
The DTA144WET1 is a PNP Silicon Bias Resistor Transistor (BRT) from the DTA114EET1 series, manufactured by onsemi. It integrates a single transistor with a monolithic bias network consisting of two resistors: a series base resistor (R1) and a base-emitter resistor (R2). The device features an R1 value of 47 kΩ and an R2 value of 22 kΩ. Key electrical ratings include a collector-base voltage (VCBO) of 50 Vdc, a collector-emitter voltage (VCEO) of 50 Vdc, and a maximum collector current (IC) of 100 mAdc. It is housed in the SC-75/SOT-416 package designed for low power surface mount applications.
Feature Summary
- Integrates a PNP transistor with a monolithic bias network to replace discrete components
- Reduces board space and component count in circuit designs
- SC-75/SOT-416 package supports wave or reflow soldering with modified gull-winged leads
Applications
- Inverter circuits
- Interface circuits
- Driver circuits
Procurement Notes
Verify the specific ordering suffix to confirm package type and shipping configuration. Confirm RoHS compliance status if required for the assembly process. Check the latest datasheet revision for any updates to thermal characteristics or mechanical dimensions before finalizing procurement specifications.
Selection Notes
Select this component when a PNP digital transistor with a 47 kΩ base resistor and 22 kΩ emitter-base resistor is required. Ensure the application operates within the 50 Vdc voltage limits and 100 mA current capacity. Consider the SC-75 package size constraints and thermal dissipation requirements relative to the ambient temperature conditions.
Part Context
This part belongs to the DTA114EET1 Series, which includes various PNP BRT configurations with different resistor ratios. The series is designed to simplify circuit design by eliminating external bias resistors. The DTA144WET1 specifically offers a unique resistor combination compared to other members like the DTA114EET1 or DTA144EET1.
