Overview
The DTA113ZKAT146 is a PNP digital transistor manufactured by Rohm Semiconductor, featuring built-in bias resistors for simplified circuit design. It operates with a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes an internal base resistor (R1) of 1 kOhms and an emitter-base resistor (R2) of 10 kOhms. Key electrical characteristics include a DC current gain (hFE) minimum of 33 at -5 mA and -5 V, and a transition frequency of 250 MHz. Power dissipation is rated at 200 mW, housed in a surface-mount SOT-23-3 package.
Feature Summary
- Integrates biasing resistors to eliminate external input components for inverter circuits
- Provides high-speed switching capabilities suitable for digital logic applications
- Offers compact surface-mount packaging for space-constrained designs
Applications
- Digital interface circuits
- Logic level shifting
- Inverter circuits
Procurement Notes
Verify the specific suffix KAT146 against the official Rohm datasheet to confirm tape-and-reel quantity and packaging specifications. Ensure compatibility with standard SOT-23-3 footprint requirements during procurement planning. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and lead times.
Selection Notes
Select this component when a PNP digital transistor with a 1:10 resistor ratio is required. Verify that the -50 V voltage rating and -100 mA current capacity meet the load requirements. Confirm that the SOT-23-3 package dimensions fit the PCB layout constraints compared to alternative packages like SC-75A or UMT3.
Part Context
This part belongs to the Rohm DTA113 series of digital transistors. It serves as a PNP counterpart to NPN variants such as the DTC113 series. The series is designed to replace discrete BJT and resistor combinations, reducing board space and assembly complexity in consumer electronics and industrial control systems.
Replacement Considerations
The DTA113ZU3T106 is a documented replacement option within the same family, offering similar electrical characteristics in a SOT-323 package. Verify pinout compatibility and thermal performance differences between the SOT-23-3 and SOT-323 packages before substitution.
