MT3S16U(TE85L,F)

Overview

The MT3S16U(TE85L,F) is a silicon NPN epitaxial planar RF transistor manufactured by Toshiba Semiconductor and Storage. Designed for UHF band oscillator and amplifier applications, it features high transition frequency and flat reverse transfer capacitance characteristics. The device operates in an SC-70 (USM) surface-mount package with three terminals: Base, Emitter, and Collector. Key electrical parameters include a collector-emitter voltage of 5 V, continuous collector current of 60 mA, and power dissipation of 100 mW at 25°C. It achieves a typical noise figure of 2.4 dB and insertion gain of 4.5 dB at 1 GHz.

Feature Summary

• Flat reverse transfer capacitance characteristic to minimize feedback variations.
• Low noise figure suitable for sensitive receiver front-end stages.

Applications

• UHF band oscillator circuits
• RF amplifier stages
• Low-noise signal processing

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notifications as availability may be restricted. Ensure proper electrostatic discharge handling protocols are followed during storage and assembly to prevent damage to the sensitive semiconductor junctions.

Selection Notes

Select this component for designs requiring low noise performance in the UHF spectrum. Verify that the operating voltage remains within the 5 V collector-emitter limit and that thermal management accommodates the 100 mW power dissipation rating. Ensure the SC-70 package footprint matches the PCB layout requirements for reliable surface mounting.
