Feature Benefit Bullets

Polarity or Channel Type: N-CHANNEL

N-CHANNEL FETs typically have lower ON resistance and higher efficiency compared to P-CHANNEL FETs, making them a preferred choice for many applications.

Surface Mount: YES

Surface mount FETs are easier to integrate into compact designs and are suitable for automated assembly processes, saving time and cost in production.

Maximum Drain Current (Abs) (ID): 4.5 A

With a high maximum drain current rating, this FET can handle higher power loads without overheating or failing, improving overall performance and reliability.

Maximum Power Dissipation (Abs): 2.4 W

The low maximum power dissipation ensures efficient operation and prevents the FET from getting damaged due to excess heat, increasing its lifespan.

Field Effect Transistor Technology: METAL-OXIDE SEMICONDUCTOR

Metal-oxide semiconductor technology offers high switching speeds, low gate drive requirements, and low leakage current, making it ideal for various switching applications.

Maximum Operating Temperature: 175 °C

With a high maximum operating temperature, this FET can withstand elevated temperatures, ensuring reliable performance in demanding environments.

Minimum Operating Temperature: -55 °C

The low minimum operating temperature allows the FET to function in cold conditions without any performance issues, increasing its versatility for different applications.

Terminal Finish: TIN LEAD

Tin lead terminal finish provides good solderability and conductivity, ensuring secure connections and long-term reliability in circuitry.

Maximum Time At Peak Reflow Temperature (s): 40

The specified maximum time at peak reflow temperature helps in preventing thermal damage during soldering processes, maintaining the integrity of the FET.

Peak Reflow Temperature °C: 260

The high peak reflow temperature tolerance allows for proper soldering without compromising the FET's performance, ensuring a reliable and durable connection.
