NST3904DXV6T1

Overview

The NST3904DXV6T1 is a dual NPN bipolar junction transistor manufactured by onsemi, housed in an SOT-563-6 surface-mount package. It features a maximum DC collector current of 200 mA and a collector-emitter voltage rating of 40 V. The device operates within a temperature range of -55°C to +150°C and has a power dissipation capacity of 500 mW. Key electrical parameters include a collector-base voltage of 40 V, an emitter-base voltage of 5 V, and a minimum DC current gain (hFE) of 60. The transition frequency is specified at 250 MHz, with a collector-emitter saturation voltage of 400 mV.

Feature Summary

• Dual NPN configuration integrated into a compact SMD footprint for space-constrained designs
• High-speed switching capability supported by a 250 MHz transition frequency
• Robust thermal performance allowing operation up to 150°C junction temperature

Applications

• General-purpose signal switching and amplification circuits
• Low-voltage digital logic interface applications
• Portable electronic devices requiring small form-factor transistors

Procurement Notes

Verify the exact suffix against official manufacturer documentation, as standard distribution often utilizes NST3904DXV6T1G. Confirm RoHS compliance status and specific tape-and-reel quantities directly with authorized distributors or the manufacturer to ensure alignment with project requirements.

Selection Notes

Select this component when a dual NPN topology is required in an SOT-563 package. Ensure the 40V voltage rating and 200mA current limit meet circuit demands. Compare hFE minimums and saturation voltages against alternative dual BJT packages if board space permits other form factors.

Part Context

This part belongs to the NST3904DXV6 series of dual general-purpose transistors. It serves as a complementary counterpart to PNP variants like the NST3906DXV6T1G, enabling push-pull or differential amplifier configurations within a single six-pin surface-mount package.

Replacement Considerations
