Overview
The DTA144TXV3T1G is a PNP digital transistor (BRT) from onsemi, integrating a single transistor with a monolithic bias resistor network. It features a typical input resistance of 47 kOhms and a typical resistor ratio of 2.1. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. It operates within a temperature range of -55°C to +150°C, with a power dissipation of 200 mW. Packaged in SC-75-3 (SOT-363), it offers a minimum DC current gain (hFE) of 80.
Feature Summary
- Integrates a PNP transistor with a monolithic bias resistor network consisting of series base and base-emitter resistors.
- Designed to replace discrete devices and external resistor networks, reducing system cost and board space.
- Optimized for low-power surface mount applications with high thermal stability.
Applications
- General-purpose switching circuits
- Driver circuits for logic interfaces
- Biasing networks in portable electronics
Procurement Notes
Verify the exact suffix 'XV3' against official datasheets, as standard listings often use 'ET1G'. Confirm RoHS compliance and material composition declarations via manufacturer documentation. Ensure the SC-75-3 package matches design constraints. Check for AEC-Q101 qualification if automotive application is required, as this specific variant may differ from standard industrial grades.
Selection Notes
Select this component when a PNP digital transistor with 47 kOhm input resistance is required. Compare hFE minimums and power dissipation ratings against circuit load requirements. Verify that the SC-75-3 footprint fits the PCB layout. Consider thermal management capabilities given the 200 mW dissipation limit in enclosed spaces.
Part Context
This part belongs to the DTA144WE series of pre-biased transistors. It shares functional similarities with other BRTs but differs in internal resistor values and packaging. The XV3 suffix typically denotes specific tape-and-reel or environmental specifications distinct from the ET1G variant.
Replacement Considerations
DTA144WET1G is a verified equivalent with identical electrical characteristics and SC-75-3 packaging. DTC144WET1G is an NPN alternative requiring circuit polarity adjustment. Always verify pinout compatibility before substitution.
