DTC123TCAT116

Overview

The DTC123TCAT116 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It integrates bias resistors with typical values of R1=2.2 kΩ and R2=2.2 kΩ. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, a continuous collector current (IC) of 100 mA, and a power dissipation (PD) of 350 mW. The device features a minimum DC current gain (hFE) of 100 at IC=1 mA and VCE=5 V, with a maximum operating frequency of 250 MHz. It operates within a temperature range up to +150°C.

• Enables direct configuration of inverter circuits through simplified on/off control logic.

Applications

• Inverter circuits
• Interface applications
• Driver circuits

Procurement Notes

Verify the specific suffix AT116 against official ROHM documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure compatibility with automated pick-and-place equipment requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for low-current switching tasks. The 2.2 kΩ resistor ratio suits standard logic interface levels. Verify that the 100 mA collector current and 50 V breakdown voltage meet the target application's load requirements. Consider the SOT-23-3 footprint constraints 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 resistive networks to reduce board space and assembly complexity. The DTC123 variant specifically denotes an NPN configuration with equal base and emitter bias resistors, widely used in general-purpose switching and signal inversion roles.
