DTC144WCAT116

Overview

The DTC144WCAT116 is an NPN digital transistor with built-in bias resistors, manufactured by ROHM Semiconductor. It operates with a supply voltage of 50V and a maximum collector current of 100mA. The device features an input resistance (R1) of 47kΩ and an emitter-base resistance (R2) of 22kΩ. Packaged in the SOT-23 (SST3) format, it supports surface-mount installation. Key electrical parameters include a transition frequency of 250MHz, a DC current gain of 56, and a power dissipation rating of 200mW on a reference footprint.

Feature Summary

Built-in thin-film bias resistors enable inverter circuit configuration without external input resistors.
Complete isolation between bias resistors allows for negative input biasing.
Elimination of parasitic effects through integrated resistor design simplifies circuit layout.

Applications

Switching circuits
Inverter circuits
Interface circuits
Driver circuits

Procurement Notes

Verify the specific ordering suffix CAT116 to confirm the tape-and-reel packaging format and quantity. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before placing orders. Ensure storage conditions adhere to humidity barrier bag requirements to maintain solderability.

Selection Notes

Select this component when a single NPN digital transistor with a 47kΩ input resistor and 22kΩ emitter-base resistor is required. Verify that the 50V collector-emitter voltage and 100mA collector current ratings meet the application's load requirements. Consider the SST3 package dimensions for PCB layout compatibility.

Part Context

This part belongs to the DTC144WCA series of NPN digital transistors from ROHM. It is designed as a replacement for discrete resistor-transistor networks, offering space savings and simplified design. The complementary PNP version is available as the DTA144WCA.
