PMBT3904VS,115

Overview

The PMBT3904VS,115 is a dual NPN switching transistor housed in the SOT666 surface-mount package. It integrates two independent transistors within an ultra-small footprint measuring 1.6 mm x 1.2 mm x 0.55 mm with a 0.5 mm lead pitch. Each transistor supports a collector-emitter voltage of 40 V and a continuous collector current of 200 mA. The device features a DC current gain (hFE) ranging from 100 to 300 at 10 mA. Total power dissipation reaches 360 mW per device, with individual transistor limits at 240 mW. Transition frequency is specified at 300 MHz.

Feature Summary

• Integrates two general-purpose NPN transistors into a single compact component
• Utilizes an ultra-small and flat lead SMD plastic package for board-space reduction
• Designed specifically for high-speed switching applications

Applications

• General-purpose switching circuits
• Amplification stages
• Digital logic interface buffers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to confirm packaging details and availability status. Ensure that design-in requirements align with the non-automotive qualification status documented in the latest product data sheet revision. Confirm compliance with RoHS directives prior to final procurement decisions.

Selection Notes

Select this component when space constraints require integrating two discrete NPN transistors into a minimal footprint. The SOT666 package offers lower thermal resistance compared to larger packages while maintaining standard switching performance. Evaluate the 40 V rating and 200 mA current limit against circuit load requirements to ensure operation remains within absolute maximum ratings.

Part Context

This part belongs to Nexperia's portfolio of small-signal switching transistors designed for modern electronics manufacturing. The SOT666 package represents a specialized form factor distinct from standard SOT-23 or SC-70 variants, prioritizing vertical integration and density. It serves as a direct replacement for dual-transistor solutions requiring reduced board area.

Replacement Considerations

Direct pin-compatible replacements include other dual NPN transistors in the SOT666 package. Verify electrical parameters such as hFE ranges and saturation voltages match original design specifications before substitution.
