Overview
The DTA144WET1G is a single PNP digital transistor manufactured by onsemi, housed in an SC-75-3 (SOT-363) surface-mount package. It integrates a monolithic bias resistor network consisting of a 47 kOhm series base resistor and a 22 kOhm base-emitter resistor, yielding a typical resistance ratio of 2.1. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. With a power dissipation rating of 200 mW and a minimum DC current gain (hFE) of 80, it operates within a temperature range of -55°C to +150°C.
Feature Summary
- Integrates a single PNP transistor with a monolithic bias resistor network to replace discrete components.
- Features a 47 kOhm series base resistor and a 22 kOhm base-emitter resistor for simplified circuit design.
- Designed for low-power surface-mount applications using the compact SC-75-3 package.
Applications
- General-purpose switching circuits requiring integrated biasing.
- Low-power surface-mount digital logic interfaces.
- Battery-powered devices where board space reduction is critical.
Procurement Notes
Verify the specific suffix '1G' confirms RoHS compliance and halogen-free status as per onsemi standards. Confirm the SC-75-3 package outline matches the target PCB footprint. Ensure the 50V VCEO rating meets the system's maximum voltage requirements. Check for any recent Product Change Notices that may affect pinout or electrical characteristics.
Selection Notes
Select this component when a PNP configuration with a 47 kOhm input resistance is required. The SC-75-3 package offers a small form factor suitable for dense layouts. Compare against other DTA144 variants if different resistor ratios are needed. Ensure the 100 mA current limit aligns with the load requirements. Verify thermal management capabilities given the 200 mW power dissipation limit.
Part Context
This part belongs to the DTA144WE series of PNP silicon digital transistors from onsemi. These devices are designed to simplify circuit design by integrating bias resistors directly with the transistor die. The series is commonly used in consumer electronics and industrial control applications where space savings and reduced component count are priorities.
Replacement Considerations
DTA144WXV3T1G: Alternative packaging variant within the same series. DTA114YET1G: Similar PNP BRT but with different resistor values (10 kOhm input). Verify pinout compatibility and electrical specifications before substitution.
