Overview
The DCX143TU-7-F is a complementary pre-biased transistor pair manufactured by Diodes Incorporated, housed in an SOT-363 surface-mount package. It integrates one NPN and one PNP transistor with a single nominal input resistor (R1) of 4.7 kΩ per device. The component supports a supply voltage (VO) of 50 V and delivers a collector continuous current (IO) of 100 mA for both polarities. Peak output current reaches 100 mA, while total power dissipation is rated at 200 mW. The gain-bandwidth product (fT) is typically 250 MHz. Operating temperature ranges from -55°C to +150°C.
Feature Summary
- Integrates complementary NPN and PNP transistors within a compact SOT-363 footprint
- Includes internal bias resistors to simplify circuit design and reduce external component count
- Designed for automated assembly using standard surface-mount packaging
Applications
- General-purpose switching applications requiring complementary logic levels
- Driver circuits for low-power loads utilizing integrated biasing
- Automotive electronics compatible with AEC-Q101 qualified variants
Procurement Notes
Verify the specific ordering suffix against official distributor catalogs to ensure correct packing quantities and reel specifications. Confirm RoHS compliance status through manufacturer documentation prior to final procurement decisions. Cross-reference part markings with datasheet tables to validate authenticity upon receipt.
Selection Notes
Select this component when a matched NPN/PNP pair with identical 4.7 kΩ base resistors is required. Ensure the 50 V supply voltage rating aligns with system requirements. Verify that the 200 mW total power dissipation limit accommodates thermal constraints within the target application environment.
Part Context
This part belongs to the DCX series of 50V complementary pre-biased transistors. It shares the SOT-363 package form factor with other members like the DCX143EU and DCX143ZU, differing primarily in internal resistor configurations. The 'TU' designation specifically indicates the inclusion of a single 4.7 kΩ resistor per transistor element.
Replacement Considerations
Direct functional substitutes include DCX143EU-7-F and DCX143ZU-7-F, provided their respective resistor values match the circuit requirements.
