Overview
The DCX123JU-7R-F is a dual digital transistor from Diodes Incorporated, integrating one NPN and one PNP transistor within a single SOT-363-6 surface-mount package. It features a typical input resistance of 2.2 kOhms and a resistor ratio of 0.046. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Power dissipation is rated at 200 mW, with an operating temperature range spanning from -55°C to +150°C. The minimum DC current gain (hFE) is specified as 100.
Feature Summary
- Integrates complementary NPN and PNP transistors in a compact dual configuration
- Includes built-in biasing resistors for simplified circuit design
- Supports high-temperature operation up to 150°C
Applications
- General-purpose switching applications
- Driver circuits for low-power loads
- Logic level translation interfaces
Procurement Notes
Verify the specific suffix against manufacturer documentation to confirm reel packaging specifications. Ensure compatibility with standard SMD/SMT assembly processes for the SOT-363-6 footprint. Cross-reference electrical parameters with the official datasheet to validate performance requirements for the intended application environment.
Selection Notes
Select this component when a complementary NPN/PNP pair is required in a minimal footprint. The integrated resistor network reduces external component count compared to discrete solutions. Verify that the 50 V voltage rating and 100 mA current capacity meet the specific load requirements of the target circuit design.
Part Context
This part belongs to the DCX123 series of digital transistors manufactured by Diodes Incorporated. It shares the same internal architecture and electrical characteristics as the DCX123JU-7-F variant, differing primarily in the tape-and-reel packaging designation indicated by the 'R' suffix. Both variants utilize the SOT-363-6 package.
Replacement Considerations
The DCX123JU-7-F is a confirmed equivalent part number with identical electrical specifications and pinout configuration.
