Overview
The DTC143TM3T5G is a single NPN Digital Transistor (BRT) manufactured by onsemi, housed in an SOT-723 surface-mount package. It integrates a monolithic bias network consisting of a series base resistor and a base-emitter resistor to simplify circuit design. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The typical input resistance (R1) is 4.7 kOhms with a typical resistor ratio of 1. The device operates within a temperature range of -55°C to +150°C and features a minimum DC collector/base gain (hFE) of 160.
Feature Summary
- Integrates built-in bias resistors to eliminate the need for external input components, enabling straightforward inverter circuit configuration.
- Utilizes thin-film resistors with complete isolation to allow negative biasing of the input and minimize parasitic effects.
- Designed as a replacement for discrete transistors combined with external resistor networks to reduce component count.
Applications
- Inverter circuits
- Interface drivers
- General-purpose switching applications
Procurement Notes
Verify the specific ordering suffix against official documentation, as variations such as T5G or T5 may indicate differences in packaging or reel specifications. Confirm RoHS compliance status through the manufacturer's datasheet before procurement. Ensure the selected package type matches the intended PCB layout requirements for the SOT-723 form factor.
Selection Notes
Select this component when a compact NPN solution with integrated biasing is required for low-voltage switching. The 50 V rating and 100 mA current capacity suit general digital logic interfacing. Consider the SOT-723 package size constraints and thermal dissipation limits of 260 mW during design validation.
Part Context
This part belongs to the DTA143TM3/DTC143TM3 family of Digital Transistors from onsemi. These devices are engineered to replace individual transistors and their associated bias resistor networks. The series offers a simplified design approach by monolithically integrating the transistor and resistive network into a single semiconductor structure.
Replacement Considerations
The DTC143E and DTC143EM3 are documented equivalents within the same product family. Verify pinout compatibility and electrical parameter alignment with the original design requirements before substitution.
