DTC123YCAT116

Overview

The DTC123YCAT116 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 (SST3) surface-mount package. It integrates biasing resistors with R1 at 2.2 kΩ and R2 at 10 kΩ to simplify circuit design. The device supports a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Key electrical parameters include a minimum DC current gain (hFE) of 33 at 10 mA and 5 V, a maximum operating frequency of 250 MHz, and power dissipation of 200 mW. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates built-in biasing resistors (R1=2.2kΩ, R2=10kΩ) to eliminate external input resistor requirements for inverter circuits.

Applications

• Inverter circuits requiring simplified input biasing without external resistors.

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm exact packaging configuration and RoHS compliance status. Ensure that the selected variant matches the required thermal and electrical specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN digital transistor with integrated biasing is required for low-current switching applications. Verify that the 50V voltage rating and 100mA current capacity align with the load requirements. Confirm compatibility with standard SOT-23 footprints during PCB layout planning.

Part Context

This part belongs to the DTx series of digital transistors from ROHM Semiconductor. These devices combine bipolar junction transistors with internal bias resistors to reduce board space and assembly complexity. The DTC123YCAT116 specifically offers an NPN configuration with defined resistance ratios for standardized logic interfacing tasks.

Replacement Considerations

Consult official substitution guides for equivalent NPN digital transistors with matching pinouts and electrical ratings. Verify that any alternative component maintains the same SOT-23 package dimensions and thermal characteristics to ensure mechanical compatibility.
