Overview
The DTC143ECAT116 is a single NPN digital transistor from the ROHM DTx series, integrating bias resistors within an SOT-23-3 package. It features a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device includes a typical base resistor (R1) of 4.7 kOhms and an emitter-base resistor (R2) of 4.7 kOhms, resulting in a resistance ratio of 1. Key electrical parameters include a minimum DC current gain (hFE) of 30 at 10 mA and 5 V, a maximum operating frequency of 250 MHz, and a power dissipation (Pd) of 350 mW. The saturation voltage (VCE(sat)) is specified at 300 mV under specific test conditions.
Feature Summary
- Integrates internal bias resistors to simplify circuit design by eliminating external components.
- Provides high-speed switching capabilities suitable for applications requiring fast response times.
- Offers compact surface-mount packaging to support space-constrained board layouts.
Applications
- General-purpose switching circuits
- Inverter logic gates
- Driver circuits for low-power loads
Procurement Notes
Verify the complete part number including the suffix CAT116 to ensure correct tape-and-reel packaging specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference datasheet revision dates to ensure alignment with current manufacturing standards and reliability requirements.
Selection Notes
Select this component when a single NPN configuration with integrated biasing is required. Ensure the 100 mA collector current rating meets load demands. Verify that the 50 V breakdown voltage exceeds the maximum circuit voltage. Consider the 250 MHz transition frequency for signal integrity in higher-speed digital interfaces.
Part Context
This component belongs to the ROHM DTx series of digital transistors. These devices combine bipolar junction transistors with on-chip resistors to replace multiple discrete components. The series offers various resistance ratios and polarities to accommodate different logic interface requirements while maintaining consistent form factors.
Replacement Considerations
Direct substitutes within the same series include DTC143XCAT116 and DTC143ZCAT116. Selection depends on the required internal resistance ratio, which varies between these variants. Verify pinout compatibility and thermal characteristics before substitution.
