Overview
The NSBC144WF3T5G is an NPN Bias Resistor Transistor (BRT) from onsemi, featuring a monolithic bias network with R1 = 47 kΩ and R2 = 22 kΩ. It operates within a collector-emitter voltage of 50 Vdc and supports continuous collector currents up to 100 mAdc. The device is housed in the SOT-1123 package (Case 524AA Style 1). Electrical characteristics include a DC current gain (hFE) ranging from 80 to 140 at IC = 5.0 mA and VCE = 10 V. Thermal dissipation reaches 254 mW at 25°C ambient temperature.
Feature Summary
- Integrates a single NPN transistor with a monolithic bias resistor network to replace discrete components
- AEC-Q101 qualified for automotive applications requiring unique site and control change requirements
- Pb-Free, Halogen Free/BFR Free, and RoHS compliant construction
Applications
- Automotive systems requiring AEC-Q101 qualification
- General-purpose switching circuits
- Driver applications for relays and solenoids
Procurement Notes
Verify the specific ordering suffix T5G corresponds to the 8000-unit tape and reel shipping configuration. Confirm that the NSV prefix designation aligns with project requirements for automotive-grade parts involving unique site and control change protocols. Ensure compliance with Pb-Free and RoHS standards during component sourcing.
Selection Notes
Select this component when board space reduction and simplified circuit design are priorities. The integrated bias network eliminates external resistors, reducing overall component count. Verify that the 50 V collector-emitter voltage rating meets the maximum operating voltage requirements of the target application circuit.
Part Context
This part belongs to the DTC144W series of digital transistors manufactured by onsemi. It shares electrical specifications with other variants such as MUN2237 and DTC144WE but utilizes the SOT-1123 package. The series is designed to provide a compact solution for replacing individual transistors and their associated biasing networks.
Replacement Considerations
Direct replacements within the same datasheet include NSVDTC144WET1G and DTC144WM3T5G. These alternatives offer identical electrical performance but differ in packaging style, such as SC-75 or SOT-723. Verify pin compatibility and thermal dissipation limits before substituting.
