Overview
The LM3046MX/NOPB is a monolithic NPN transistor array manufactured by Texas Instruments, housed in a 14-pin SOIC surface-mount package. It integrates five independent NPN transistors designed for VHF band applications. Key electrical specifications include a collector-emitter breakdown voltage of 15 V, a maximum collector current of 50 mA, and a transition frequency of 120 MHz. The device operates within a temperature range of -40 °C to 85 °C and has a power dissipation rating of 750 mW. It features a minimum DC current gain (hFE) of 40 at 1 mA and 3 V, with a collector cutoff current of 0.5 μA.
Feature Summary
- Integrates five NPN transistors into a single complex configuration for space-constrained designs.
- Optimized for Very High Frequency (VHF) band signal processing and amplification.
- Utilizes lead-free packaging compliant with RoHS standards.
Applications
- VHF amplifier circuits
- RF signal processing stages
- General-purpose switching arrays
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and compliance status. Ensure the component matches the required pinout and thermal characteristics for the intended PCB layout. Confirm availability through authorized distributors to avoid counterfeit parts.
Selection Notes
Select this component when a compact solution for multiple NPN switching or amplification tasks is required in the VHF spectrum. Consider the 14-pin SOIC footprint and 750 mW thermal limits during circuit design. Verify that the 15 V collector-emitter voltage rating meets the system's operational requirements.
Part Context
The LM3046 series belongs to Texas Instruments' lineup of bipolar transistor arrays. These components are engineered to replace discrete transistor networks, reducing board space and assembly complexity. The MX/NOPB variant specifically denotes the SOIC-14 surface-mount package with lead-free construction.
Replacement Considerations
The LM3046M/NOPB is a direct equivalent part number from National Semiconductor (now TI). Other transistor arrays may serve as functional substitutes if pin compatibility and electrical ratings align, but cross-referencing datasheets is essential.
