NSVT3946DP6T5G

Overview

The NSVT3946DP6T5G is a dual complementary general-purpose bipolar junction transistor (BJT) manufactured by onsemi. It integrates an NPN and a PNP transistor within a single SOT-963 surface-mount package. The device supports a maximum collector current of 200 mA and offers a collector-emitter voltage rating of 40 V. Key electrical characteristics include a transition frequency (fT) ranging from 200 MHz to 250 MHz, a DC current gain of 100, and a collector-emitter saturation voltage of 400 mV.

Feature Summary

• Integrates complementary NPN and PNP transistors in a compact SOT-963 package for space-efficient designs.
• Provides high-speed switching capabilities with a transition frequency up to 250 MHz.
• Features low saturation voltage for efficient power management in signal processing applications.

Applications

• General-purpose signal switching
• Digital logic interface circuits
• Small-signal amplification stages

Procurement Notes

Verify the exact suffix configuration against the manufacturer's official datasheet to ensure compatibility with specific thermal and electrical requirements. Confirm that the SOT-963 package dimensions align with the target PCB footprint. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a dual complementary BJT configuration is required in a minimal footprint. The 40 V rating and 200 mA current capacity suit low-power analog and digital applications. Ensure the operating temperature range meets system constraints, as the device is designed for standard commercial environments.

Part Context

This device belongs to onsemi's portfolio of dual complementary transistors, offering a spin-off solution from traditional three-leaded devices. It replaces discrete NPN and PNP pairs, reducing board space and assembly complexity. The SOT-963 package provides a robust surface-mount option for modern electronics manufacturing.

Replacement Considerations

The NST3946DP6T5G serves as a direct functional substitute within the same product family. Verify pinout compatibility and thermal performance when transitioning between these variants to ensure circuit integrity.
