Description
Product Overview
The Bridgold BS170 170 N Channel MOSFET is a compact, high‑performance enhancement mode field‑effect transistor designed for a wide range of low‑power electronic applications. Housed in a standard TO‑92 package, this device measures 7.01 x 4.37 x 0.43 inches and weighs only 0.63 ounces, making it easy to integrate into dense circuit layouts. It is rated for a continuous drain current of 500 mA and a drain‑source voltage of 60 V, providing a reliable switching solution for small‑signal circuits. The transistor features a high input impedance, virtually eliminating loading effects on preceding stages, and it exhibits no minority carrier storage time, which translates to rapid turn‑on and turn‑off transitions. Its CMOS‑compatible gate input allows direct interfacing with modern digital logic families, while the voltage‑controlled operation simplifies circuit design by eliminating the need for complex bias networks. The BS170’s robust construction, combined with Bridgold’s rigorous quality‑control processes, ensures consistent performance across temperature ranges and long‑term reliability.
Usage
Designed with versatility in mind, the BS170 MOSFET excels in a variety of hobbyist and professional environments. It is an excellent choice for Arduino and Raspberry Pi projects that require precise control of LEDs, relays, and small DC motors, thanks to its fast switching speed and low gate‑drive requirements. In power‑supply designs, the device can be employed as a low‑dropout regulator or as part of a synchronous buck converter, where its low on‑resistance minimizes power loss. The transistor also serves well in audio amplification circuits, providing clean signal amplification without distortion due to its high input impedance. For educational laboratories, the BS170 offers a hands‑on example of MOSFET operation, allowing students to explore concepts such as threshold voltage, transconductance, and switching dynamics. Its compact size and straightforward pinout make it suitable for prototype boards, breadboards, and surface‑mount adapters alike.

FAQ
What is the maximum switching frequency for the BS170?
The BS170 can comfortably operate at frequencies up to several hundred kilohertz, making it suitable for most hobbyist PWM applications and many industrial control scenarios.
Can the BS170 be used with 5 V logic levels?
Yes, the gate threshold voltage is low enough to be fully turned on by a 5 V logic signal, allowing direct interfacing with common microcontroller platforms.
Is a heat sink required for typical usage?
For currents below 500 mA and duty cycles under 50 %, the TO‑92 package dissipates heat sufficiently without additional cooling. Higher currents or continuous operation may benefit from a small heat sink.
How does the BS170 compare to the classic 2N7000?
Both devices share similar voltage and current ratings, but the BS170 offers slightly lower on‑resistance and faster switching, providing improved efficiency in high‑speed applications.
What packaging options are available?
The BS170 is supplied in a standard TO‑92 lead‑frame, compatible with both through‑hole and surface‑mount adapters for flexible board design.
