Although small-signal MOSFET products do not match the power handling capabilities of high-power MOSFETs, they play an indispensable role in precision electronic circuits. These devices are primarily designed for low-current, low-voltage switching and amplification applications. Their excellent high-frequency characteristics and high input impedance make them an ideal choice for applications such as analogue switches, signal conditioning, and load switching. Small-signal MOSFETs, with their miniaturised packaging and low power consumption characteristics, have achieved widespread and in-depth application penetration in modern electronic devices.

Basic Structure and Operating Principles:

Small-signal MOSFETs share a similar basic structure with power MOSFETs, both featuring three terminals: source (Source), drain (Drain), and gate (Gate). However, their design priorities are fundamentally different. Small-signal MOSFETs are optimised for high-frequency response and linear region characteristics, rather than high-current handling capability. Based on channel type, they are classified into N-channel and P-channel; based on operating mode, they are further categorised into enhancement-mode and depletion-mode. ON Semiconductor's small-signal MOSFET product line covers all these types, offering design engineers a comprehensive selection. These devices are typically manufactured using planar processes, with the gate oxide layer carefully designed to ensure reliability while achieving high transconductance (gfs) and low gate charge (Qg).

Key performance parameter analysis:

Threshold voltage (Vgs(th)): Typically 0.5–3 V, suitable for direct drive in low-voltage circuits

Transconductance (gfs): Reflects the gate voltage's control over drain current; higher values indicate greater gain

Input capacitance (Ciss): Affects switching speed; small-signal MOSFETs typically have extremely low input capacitance

On-resistance (RDS(on)): Though less critical than for power MOSFETs, it still impacts signal path losses

Drain-source breakdown voltage (BVdss): Typically 20V–100V for small-signal models, meeting most signal processing requirements

Typical application scenarios:

Analogue switches and multiplexers: audio signal routing, channel switching in data acquisition systems

High-frequency amplifier circuits: RF front-ends, low-noise amplifiers (LNAs) in communication equipment

Load switches and power management: controlled on/off switching of subsystem power supplies

Signal conditioning circuits: signal conditioning and impedance transformation for sensor interfaces

Digital logic interfaces: level conversion and bus driving
