About

What are Small signal MOSFETs?

Small signal/Small power MOSFETs are generally a specific class of devices typically packaged in SOT formats, such as SOT-223, SOT-23, SOT-323, and SOT-363, as well as other similar packages like TSOP-6 and SC59. These components are characterized by their low power consumption, typically below 1 W at 25°C, making them ideal for scenarios where power efficiency is crucial. In terms of operation, Small signal MOSFETs share similarities with other MOSFETs, featuring parameters such as RDS(on) (on-resistance), breakdown voltage, and current rating. They simply serve as MOSFETs designed for applications where low(er) power is required and a compact design is needed.

Small signal portfolio for industrial applications

The small signal N-channel OptiMOS™ devices are available in the SOT-23 and SOT-223 packages. The voltage range for this family covers 60 V, 100 V, 250 V, and 600 V with RDS(on) values as low as 3000 mΩ (@VGS= 10 V).

The family includes OptiMOS™ 60 V, 100 V, and 150 V P-channel devices. They are also available in SOT-23 and SOT-223 packages and offer RDS(on) values as low as 65 mΩ (@VGS= 10 V). These devices are particularly valuable in modern technology applications, including battery management, load switches, and reverse polarity protection.

Benefits of Small signal for industrial applications

The small outline packages allow compact designs that save PCB space and reduce the end products’ cost and weight. With the availability of enhancement mode and depletion mode options, designers have flexibility in the choice of the gate drive, making design easier. 

The ability of the new devices to switch rapidly allows for highly efficient designs that are also very robust. Higher switching frequencies also enable the use of lighter and more compact passive devices (inductors and capacitors). 

Devices in this family are intended for industrial applications and exhibit a high degree of robustness. All devices are JEDEC-qualified, simplifying the approval path for designers and allowing designs to go to market more quickly.

Targeted applications

The applications in which Small signal/Small power MOSFETs can be used are almost limitless as they provide such a universal function in controlling power. Infineon's MOSFETs enable designs with an optimal price/performance ratio and a small package size. These products are ideally suited for space-constrained industrial applications such as:

  • Battery protection
  • Battery charging
  • LED lighting systems
  • Load switches
  • DC-DC conversion
  • Level shifters
  • Low-voltage drives
  • Microcontroller interfacing
