The NE46234-SE-AZ is an NPN epitaxial silicon RF transistor designed for low distortion and low noise amplifier applications operating at a low supply voltage of 5 V. It features a 3-pin Power Minimold (SOT-89) package with a total power dissipation of 1.8 W on a specified ceramic substrate. Key electrical parameters include a collector-to-emitter voltage (VCEO) of 12 V, a collector current (IC) of 150 mA, and a gain bandwidth product (fT) of 6.0 GHz. The device exhibits typical intermodulation distortion values of IM2 = 55 dBc and IM3 = 76 dBc at VCE = 5 V and IC = 50 mA.
Verify the specific hFE binning classification required for the design, as the SE suffix indicates a DC current gain range of 125 to 250. Confirm that the ordering information matches the requested quantity format, such as non-reel taping or reel quantities, to ensure compatibility with assembly processes.
Select this component when designing RF amplifiers requiring low intermodulation distortion at low supply voltages. Ensure the thermal management strategy supports the 1.8 W power dissipation rating using a double-sided copper-clad ceramic substrate. Verify that the 12 V VCEO rating meets the circuit's maximum voltage requirements.
This part is functionally equivalent to the NEC 2SC4703. It belongs to a family of NPN silicon RF transistors intended for high-frequency applications. The manufacturer provides multiple hFE ranking options, including SH, SF, and SE, to accommodate different gain requirements within the same physical package and electrical specification framework.
The 2SC4703 is a confirmed equivalent part number for the NE46234 series.
