Feature Benefit Bullets

Polarity or Channel Type: N-CHANNEL

N-CHANNEL FETs are known for high efficiency and fast switching speeds, making this product suitable for applications requiring precise control.

Surface Mount: YES

Surface mount technology allows for easy and efficient PCB assembly, saving time and space in electronic designs.

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

With a high maximum drain current, this FET can handle heavy loads without overheating or compromising performance.

Maximum Power Dissipation (Abs): 2.4 W

The low power dissipation of this FET results in minimal heat generation, ensuring reliability and longevity in high-power applications.

Field Effect Transistor Technology: METAL-OXIDE SEMICONDUCTOR

Metal-oxide semiconductor technology provides high efficiency and low leakage current, making this FET ideal for low-power applications.

Maximum Operating Temperature: 175 °C

The high maximum operating temperature allows this FET to perform reliably in harsh environments or under heavy loads.

Terminal Finish: Matte Tin (Sn)

Matte Tin terminal finish provides good solderability and conductivity, ensuring secure connections in electronic circuits.

Maximum Time At Peak Reflow Temperature (s): 20

The short time at peak reflow temperature minimizes the risk of thermal damage during the soldering process.

Peak Reflow Temperature °C: 260

The high peak reflow temperature allows for reliable solder joints that can withstand harsh operating conditions.
