DTA143ZM3T5G

Overview

The DTA143ZM3T5G is a single pre-biased PNP transistor manufactured by onsemi, housed in an SOT-723 surface-mount package. It features a collector-emitter breakdown voltage of 50 V and a continuous collector current rating of 100 mA. The device integrates internal biasing resistors, specifically a base resistor (R1) of 4.7 kOhms and an emitter resistor (R2) of 47 kOhms. Key electrical characteristics include a minimum DC current gain (hFE) of 80 at 5 mA and 10 V, a maximum saturation voltage of 250 mV at 10 mA, and a power dissipation capacity of 260 mW. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates dual biasing resistors to simplify circuit design and reduce component count.
• Provides high current gain and low saturation voltage for efficient switching applications.
• Utilizes a compact SOT-723 surface-mount package suitable for space-constrained layouts.

Applications

• General-purpose switching circuits requiring integrated biasing.
• Driver stages for relays, solenoids, or small loads.
• Logic interface circuits between microcontrollers and peripheral devices.

Procurement Notes

Verify the specific suffix 'Z' indicates the inclusion of internal resistors R1 and R2 as documented in official specifications. Confirm RoHS compliance status through the manufacturer's declaration. Ensure the SOT-723 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required. Compare the 4.7 kOhm base resistance against other variants if different input impedance levels are needed. Verify that the 50 V voltage rating and 100 mA current capacity meet the specific load requirements of the application design.

Part Context

This part belongs to the DTA143 series of pre-biased transistors from onsemi. It shares the same core transistor structure as the DTA143TM3T5G but differs in packaging and potentially internal resistor configurations. The series is designed to replace discrete resistor-transistor networks in digital switching applications.

Replacement Considerations

DTA143TM3T5G is a related variant within the same product family. Verify pinout compatibility and exact resistor values before substitution. Other manufacturers offer equivalent pre-biased PNP transistors in SOT-723 packages; ensure electrical parameters match the original design specifications.
