LM3046M/NOPB

Overview

The LM3046M/NOPB is a lead-free, plastic SOIC-14 bipolar RF small signal transistor array manufactured by Texas Instruments. It contains five NPN transistors configured in a complex arrangement within a single package. The device operates in the Very High Frequency (VHF) band with a transition frequency of 120 MHz. Key electrical specifications include a maximum collector current of 50 mA, a collector-emitter breakdown voltage of 15 V, and a collector-base voltage of 20 V. The unit supports a power dissipation of 750 mW and maintains an operating temperature range from -40 °C to 85 °C. It features a minimum DC current gain (hFE) of 40 at 1 mA and 3 V.

Feature Summary

• Integrated five-channel NPN transistor array for compact circuit design
• Optimized for low noise performance in VHF band applications
• Surface-mount SOIC-14 packaging for automated assembly

Applications

• VHF radio frequency amplifier stages
• Low noise signal processing circuits
• RF front-end modules requiring multiple matched transistors

Procurement Notes

Verify the component authenticity against Texas Instruments official documentation before integration. Confirm that the specific order suffix matches the required RoHS compliance and lead-free status. Ensure the receiving facility handles the SOIC-14 package according to standard surface mount guidelines. Cross-reference the datasheet revision date to ensure parameter consistency with your design requirements.

Selection Notes

Select this component when a multi-transistor solution is needed for VHF frequencies without occupying excessive board space. The 15 V collector-emitter rating suits low-voltage RF systems. Consider the 750 mW thermal dissipation limit during layout planning. Verify that the 120 MHz transition frequency meets the specific signal bandwidth requirements of the target application.

Part Context

This part belongs to the LM3046 series of bipolar transistor arrays produced by Texas Instruments. It serves as a discrete semiconductor alternative to integrated RF modules, offering flexibility in custom biasing and configuration. The NOPB suffix indicates compliance with environmental standards, specifically being lead-free and RoHS compliant, aligning with modern manufacturing regulations.
