Description
Product Overview
The BF998R N-Channel MOSFET is a high‑quality semiconductor device engineered for reliable performance in a wide range of electronic applications. Each unit is housed in a compact SOT‑143 package, measuring just a few millimeters on each side, which makes it ideal for space‑constrained designs. The device operates at a maximum drain‑source voltage of 12 V and can handle a continuous drain current of up to 30 mA, providing a balance of low power consumption and sufficient switching capability for many low‑voltage circuits.
Manufactured by GODIYMODULES, a reputable supplier known for stringent quality control, the BF998R MOSFET benefits from a robust silicon substrate and a carefully designed gate structure that minimizes leakage and ensures fast turn‑on and turn‑off times. The 20‑piece pack includes identical units, each tested to meet the specified electrical parameters, guaranteeing consistency across your entire project. The MOSFET’s low on‑resistance reduces power loss, which is especially valuable in battery‑powered or energy‑efficient designs.
Key specifications include a drain‑source voltage (VDS) of 12 V, a gate threshold voltage (VGS(th)) ranging from 0.8 V to 2.5 V, and a maximum power dissipation of 0.2 W. The device also features a fast switching speed, making it suitable for pulse‑width modulation (PWM) control, digital logic level interfacing, and other fast‑switching applications. Its SOT‑143 footprint allows for easy placement on standard printed circuit boards (PCBs) without requiring special mounting techniques.

Usage
The BF998R MOSFET is designed for use in a variety of industrial and hobbyist environments. Its low voltage rating makes it perfect for controlling LED arrays, small DC motors, and low‑power relays in automation systems. Engineers often incorporate the device into power‑management modules, such as step‑down converters and voltage regulators, where its fast switching characteristics improve overall efficiency.
In addition to industrial applications, the MOSFET is well‑suited for educational projects, prototype development, and DIY electronics. Hobbyists building Arduino or Raspberry Pi accessories can rely on the BF998R to provide reliable switching for sensor interfaces, motor drivers, and communication modules. The device’s compatibility with standard logic levels means it can be directly driven by 3.3 V or 5 V microcontroller outputs without the need for additional level‑shifting circuitry.
Because the MOSFET is packaged in a SOT‑143 case, it can be mounted on both through‑hole and surface‑mount PCBs, offering flexibility for designers who prefer hand‑soldering or automated assembly processes. The component’s small size also reduces overall board real estate, allowing more functionality to be packed into compact devices such as wearable electronics, portable instrumentation, and IoT sensors.
