The Vishay Intertechnology IRF840 N-channel MOSFET Field Effect Transistor is a versatile semiconductor component suitable for various power electronics applications. This bulk pack of 50 pieces offers excellent value for those requiring a large quantity of these transistors for their projects.
The IRF840 is a high-performance, medium power, N-channel, enhancement-mode MOSFET. It features a drain-source channel resistance (Rds(on)) of approximately 5.2 at a drain-source voltage (Vds) of 10 V and a gate-source voltage (Vgs) of 10 V. This low Rds(on) value ensures efficient power conversion and minimal power loss in the transistor.
The IRF840 can handle a continuous drain current (Id) of up to 33.6 A with a maximum drain-source voltage of 100 V. It also offers a high voltage gain (hFE) of approximately 25 at a Vds of 10 V and a Vgs of 15 V. These specifications make the IRF840 an excellent choice for applications that require high current handling capability and good voltage control.
The IRF840 is designed with a thermally enhanced, 10-lead TO-220 package, which ensures efficient heat dissipation and stable operation under heavy loads. The large, flat copper pad on the bottom of the package facilitates improved thermal conductivity and easier soldering.
The MOSFET also features an integrated body diode that allows for reverse voltage blocking of up to 50V. This diode can be utilized to recover energy during the regenerative braking phase in motor applications.
With a maximum temperature rating of 125 C, the IRF840 can withstand harsh thermal environments. Its low on-resistance and high current handling capability make it an ideal candidate for various power electronics applications, including motor control circuits, power supplies, and DC-DC converters. Additionally, the IRF840's small size and compact packaging make it perfect for use in space-constrained designs.
In summary, the Vishay Intertechnology IRF840 N-channel MOSFET is a high-performance, medium power, enhancement-mode MOSFET designed for various power electronics applications. With a low Rds(on), high voltage gain, and high current handling capability, this bulk pack of 50 pieces offers excellent value for those requiring a large quantity of these transistors. Its thermally enhanced TO-220 packaging ensures efficient heat dissipation and stable operation under heavy loads, making it a versatile and reliable component for power electronics projects.
Vishay's IRF840 N-channel MOSFET is a popular choice for various applications due to its reasonable power handling capability and good electrical performance. Here are some pros and cons of buying 50 pieces of the IRF840 MOSFET:
Pros:1. Wide operating temperature range (-40 C to 150 C), making it suitable for various environments.
2. Relatively high continuous drain current (up to 33A) for a low-power MOSFET.
3. Low Rds(on) value (0.12 at 25 C), which results in low power loss in on-state.
4. Easy to use in a wide array of applications, such as power conversion circuits, motor controllers, and switch mode power supplies.
5. Good availability and competitive pricing in the market.
Cons:1. The IRF840 has a relatively high on-resistance (Rds(on)) compared to newer, more advanced MOSFETs.
2. The gate-source voltage (Vgs) threshold is not very low (minimum Vgs of 10V), which may require additional gate drive circuitry for certain applications.
3. The MOSFETs may exhibit some variation in electrical characteristics between individual devices.
4. Larger heat sinks or thermal management solutions may be required for high-power applications to maintain safe operating temperatures.
Conclusion:The Vishay IRF840 N-channel MOSFET offers good power handling capability, wide operating temperature range, and ease of use at a competitive price point. However, it has a relatively high on-resistance and gate-source voltage threshold compared to newer MOSFETs, and may require additional gate drive circuitry or thermal management solutions for high-power applications. Ultimately, the decision to buy the IRF840 MOSFET depends on the specific requirements of your project and the tradeoffs between power handling, electrical performance, cost, and ease of use.
Recommendation:If your project requires a low-power MOSFET with good electrical performance and wide temperature range, the Vishay IRF840 is a solid choice. However, if you need a MOSFET with lower on-resistance or gate-source voltage threshold, you may want to consider more advanced and newer MOSFETs with better electrical performance, such as the IRF5402N or the IRFB4110PBF. If cost is a major concern, consider purchasing the IRF840 in larger quantities to take advantage of volume discounts.
