NSVDTA144EET1G

Overview

The NSVDTA144EET1G is a single PNP Bias Resistor Transistor (BRT) manufactured by onsemi. It integrates a silicon NPN transistor with a monolithic bias resistor network consisting of a series base resistor and a base-emitter resistor within an SC-75 (SOT-416) surface-mount package. The device features a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. Typical internal resistance values include a base resistor (R1) of 4.7 kOhms and a base-emitter resistor (R2) of 47 kOhms, yielding a typical resistance ratio of approximately 10. The component supports a power dissipation of 200 mW and operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates a single PNP transistor with dual bias resistors to replace discrete components
• Monolithic construction reduces printed circuit board space and system assembly cost
• Surface-mount packaging designed for low-power applications

Applications

• General-purpose switching circuits in consumer electronics
• Driver stages for relays and small motors
• Logic level translation and interface buffering

Procurement Notes

Verify the specific suffix EET1G against the manufacturer's official datasheet to confirm the exact resistance values and package variant. Ensure that the ordering information matches the required electrical characteristics and RoHS compliance status before procurement. Cross-reference the part number with authorized distributors to confirm availability and authenticity.

Selection Notes

Select this component when a compact solution for driving loads or interfacing logic levels is required. The integrated bias network simplifies circuit design by eliminating external resistors. Verify that the 50 V voltage rating and 100 mA current capacity meet the application requirements. Consider the thermal performance and power dissipation limits relative to the PCB layout and ambient operating conditions.

Part Context

This part belongs to the DTA144 series of digital transistors from onsemi. These devices are engineered to simplify circuit design by combining a transistor and bias resistors into a single package. The series is widely used in applications requiring reliable switching performance in a minimal footprint, serving as a direct replacement for discrete transistor-resistor combinations in various electronic systems.

Replacement Considerations

Compatible substitutes include the DTA144EET1G and other DTA144 series variants from onsemi or equivalent manufacturers such as ROHM Semiconductor, provided the pinout, voltage ratings, and resistance values match the original design specifications.
