PZTA14T3

Single Bipolar Transistors Overview

The PZTA14T3 is a single NPN digital transistor (BRT) manufactured by onsemi, housed in the SOT-723 surface-mount package. It integrates an NPN bipolar junction transistor with two built-in bias resistors to simplify circuit design and reduce component count. The device features a collector-emitter voltage rating of 50 V and a continuous collector current capacity of 100 mA. Typical internal resistor values are 4.7 kOhms for the base resistor and 47 kOhms for the emitter resistor, providing a standard resistance ratio. The unit supports a maximum power dissipation of 260 mW and operates within a temperature range of -55°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix T3G against the ordered part number to ensure correct packaging configuration. Confirm RoHS compliance status and automotive qualification requirements if applicable to the target environment. Cross-reference the datasheet revision date to ensure alignment with current manufacturing specifications and pinout definitions before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when a compact NPN switching solution with integrated biasing is required. The SOT-723 package offers space savings compared to traditional through-hole alternatives. Ensure the application voltage does not exceed the 50 V collector-emitter limit and that the load current remains within the 100 mA continuous rating. Consider thermal management for power dissipation near the 260 mW maximum in enclosed environments.

Single Bipolar Transistors Part Context

This device belongs to the PZTA series of digital transistors from onsemi, designed to replace discrete resistor-transistor networks. The series provides standardized biasing configurations to streamline design workflows. The PZTA14 variant specifically utilizes a 4.7k/47k resistor combination, offering a balanced gain characteristic for general switching tasks in consumer and industrial electronics.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include the DTA143TM3T5G for PNP polarity equivalents or other SOT-723 NPN BRTs with matching 50V ratings. Verify pin compatibility and internal resistor ratios when swapping manufacturers. Ensure the replacement maintains the same thermal and electrical performance characteristics.
