DTA143ZKAT146

Overview

The DTA143ZKAT146 is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors for simplified circuit design. It operates with a collector current of -100 mA and a supply voltage of -50 V. The device incorporates a typical input resistance (R1) of 4.7 kOhms and an emitter-base resistance (R2) of 47 kOhms, resulting in a resistor ratio of 10. Packaged in the SOT-323-3 form factor, it supports surface mount installation and maintains a maximum power dissipation of 200 mW. The component ensures reliable performance with a minimum DC current gain (hFE) of 80 at -10 mA and -5 V, while sustaining a maximum operating frequency of 250 MHz.

Feature Summary

Integrates thin-film bias resistors to eliminate external components and reduce parasitic effects.
Provides high-speed switching capability suitable for interface and driver applications.
Offers compact surface-mount packaging for efficient board space utilization.

Applications

Inverter circuits
Interface logic drivers
General-purpose switching

Procurement Notes

Verify the specific suffix KAT146 against official ROHM documentation to confirm the exact reel quantity and tape specifications. Ensure compatibility with standard SMT reflow profiles and check for RoHS compliance status in the latest datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with a 10:1 internal resistor ratio is required. Compare the 4.7 kOhm base resistance against alternative models like DTA143EK if different drive currents are needed. Confirm that the SOT-323 package dimensions fit the designated footprint on the printed circuit board.

Part Context

This part belongs to the DTA143 series of PNP digital transistors from ROHM Semiconductor. It shares functional similarities with other variants such as DTA143ZU3T106 but differs in packaging and specific ordering suffixes. The series is designed for general-purpose digital switching tasks requiring integrated biasing.

Replacement Considerations

DTA143ZU3T106 offers similar electrical characteristics within the same family. Verify pinout compatibility and package dimensions before substitution. Consult official ROHM resources for approved cross-reference data.
