DTA144GKAT146

Overview

The DTA144GKAT146 is a single PNP pre-biased digital transistor manufactured by ROHM Semiconductor. It features an integrated base resistor (R1) of 10 kΩ and an emitter-base resistor (R2) of 47 kΩ within a compact SMT3 (SOT-346/SC-59) surface-mount package. The device supports a maximum collector-emitter voltage (Vceo) of 50 V and a continuous collector current (Ic) of 100 mA. Key electrical specifications include a minimum DC current gain (hFE) of 30 at Ic=5mA, Vce=5V, and a transition frequency (fT) of 250 MHz. Maximum power dissipation is rated at 200 mW, with a maximum operating temperature of +150 °C.

Feature Summary

Integrates dual resistors for simplified circuit design and reduced component count
Provides high-speed switching capability with a 250 MHz transition frequency
Offers robust thermal performance with a maximum junction temperature of 150 °C

Applications

General-purpose signal switching in consumer electronics
Driver circuits for small-signal loads in portable devices
Logic interface buffering between microcontrollers and peripheral components

Procurement Notes

Verify the specific suffix 'KAT146' to confirm the exact resistance values and tape-and-reel packaging configuration. Confirm RoHS compliance status and check for obsolescence notices, as some distributors list this part as not recommended for new designs. Ensure the ordering quantity matches the standard reel size of 3,000 units if full reels are required.

Selection Notes

Select this component when a PNP pre-biased transistor with a 10 kΩ base resistor is required. Compare against variants like DTA144EKA or DTA144GKA if different internal resistance ratios are needed. Consider the SMT3 package dimensions for PCB layout constraints and verify that the 50V voltage rating meets the application's peak load requirements.

Part Context

This part belongs to ROHM's DTA144 series of standard digital transistors. These devices combine bipolar junction transistors with internal biasing resistors to replace multiple discrete components. The series offers various resistance combinations and polarity options, providing a standardized solution for switching applications across industrial and consumer markets.
