Overview
The DTA124XKAT146 is a single PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates with a collector-emitter voltage of -50V and a continuous collector current of -100mA. The device includes an input resistor (R1) of 22 kOhms and an emitter-base resistor (R2) of 47 kOhms, yielding a typical resistance ratio of 2.1. Key electrical characteristics include a minimum DC current gain (hFE) of 68 at -5V and -5mA, a transition frequency of 250 MHz, and a power dissipation rating of 350 mW. It is housed in a compact SOT-23-3 surface-mount package.
Feature Summary
- Integrates bias resistors to eliminate external components for inverter circuits
- High-speed switching capability with a 250 MHz transition frequency
- Compact SOT-23-3 surface-mount packaging for space-constrained designs
Applications
- General-purpose inverter circuits
- Interface driver applications
- Logic level translation
Procurement Notes
Verify the specific suffix KAT146 against official ROHM documentation to confirm tape-and-reel quantities and RoHS compliance status. Ensure the ordering code matches the exact pinout and electrical tolerances required for the target application before finalizing procurement.
Selection Notes
Select this component when a PNP digital transistor with a 22 kOhm base resistor is required. Verify that the -50V collector-emitter voltage and -100mA current ratings exceed the maximum load requirements. Confirm compatibility with the SOT-23-3 footprint during PCB layout.
Part Context
This part belongs to the ROHM DTx series of bias resistor built-in transistors. These devices are designed to replace discrete BJT and resistor combinations, reducing board space and assembly costs. The DTA124X variant specifically denotes the PNP polarity and standard resistor values within this product family.
Replacement Considerations
Cross-reference with other ROHM DTA124 variants such as DTA124XCA or DTA124EKAT146 if different packaging or slight parameter variations are acceptable. Verify that substitute parts maintain the same SOT-23-3 pin configuration and electrical specifications.
