NST3946DXV6T1G

Overview

The NST3946DXV6T1G is a dual bipolar junction transistor (BJT) array manufactured by onsemi, integrating one NPN and one PNP transistor within a single SOT-563-6 surface-mount package. The device supports a maximum continuous collector current of 200 mA and operates with a collector-emitter voltage (VCEO) of 40 V. Key electrical specifications include a collector-base voltage (VCBO) ranging from 40 V to 60 V and an emitter-base voltage (VEBO) between 5 V and 6 V. Power dissipation is rated at 500 mW, with a gain-bandwidth product (fT) of 300 MHz for the NPN section and 250 MHz for the PNP section. The component functions reliably across an operating temperature range of -55°C to +150°C.

Feature Summary

• Integrates complementary NPN and PNP transistors in a compact SOT-563-6 package to minimize board space.
• Provides high-speed switching capabilities with a gain-bandwidth product reaching up to 300 MHz.
• Supports wide thermal operation from -55°C to +150°C for robust performance in demanding environments.

Applications

• General-purpose signal switching and logic interface circuits
• Driver stages for low-power loads requiring complementary output
• Digital-to-analog conversion buffer stages

Procurement Notes

Verify the specific ordering suffix T1G against the manufacturer's latest documentation to confirm packaging details and compliance status. Confirm availability through authorized channels as distribution status may vary. Ensure the procurement source provides valid traceability and authenticity guarantees for this semiconductor component.

Selection Notes

Select this component when a matched NPN/PNP pair is required in a small footprint. Compare the 40 V VCEO rating against circuit requirements. Evaluate the 500 mW power dissipation limit relative to thermal management constraints. Consider the SOT-563-6 package dimensions for PCB layout compatibility.
