DTC123JCAT116

Overview

The DTC123JCAT116 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It features built-in bias resistors with typical values of 2.2 kΩ for the input resistor and 47 kΩ for the emitter-base resistor. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Key electrical specifications include a minimum DC current gain (hFE) of 80 at 10 mA and 5 V, a maximum operating frequency of 250 MHz, and a power dissipation rating of 350 mW. The component operates within a temperature range up to +150°C.

Feature Summary

• Integrates bias resistors to simplify circuit design by eliminating external input components.
• Provides high-speed switching capabilities suitable for digital logic applications.

Applications

• Inverter circuits requiring simplified input stages
• Driver circuits for relays and solenoids
• Logic level shifting between different voltage domains

Procurement Notes

Verify the specific suffix 'T116' corresponds to the required tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering part number matches the exact pinout and electrical tolerances defined in the latest datasheet to avoid compatibility issues during assembly.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for space-constrained designs. Compare the 2.2 kΩ input resistance against other variants if specific base drive currents differ. Verify that the 50 V voltage rating meets the system's maximum signal levels. Consider the SOT-23-3 footprint constraints relative to available PCB real estate.

Part Context

This part belongs to the DTx series of Bias Resistor Built-in Transistors from ROHM Semiconductor. These devices combine a bipolar junction transistor with internal resistive networks to reduce board space and component count. The JCA variant specifically denotes the resistor ratio and package type within the broader product family.

Replacement Considerations

DTC123ECA is a similar NPN digital transistor with identical SOT-23-3 packaging and pinout but features different internal resistor values (4.7 kΩ input). Verify functional equivalence before substitution as the biasing characteristics will change.
