FMMD914TA Discrete Semiconductor Products

The FMMD914TA is a small surface mounted single diode rectifier used in various electronic applications. It is typically used as a low-cost alternative to its larger counterparts, such as the FREDR914TA, and is suitable for use in a variety of high-current applications where space is at a premium.

The FMMD914TA is a silicon-based rectifier with a maximum reverse-voltage rating of 1000 volts (1 kV) and a peak forward-current rating of 9 amps (9 A). It features an internal Schottky diode structure, making it suitable for high-frequency applications. It possesses a reverse-recovery time of only 200 nanoseconds, making it one of the fastest such rectifiers on the market.

The FMMD914TA is primarily used in automotive and industrial applications, where high-current electronic components are required. It can be used to power electrical motors, power supplies, and various other devices. In automotive applications, it is often used to control lighting systems and to protect sensitive components from damage. The diode’s low profile is also useful for applications where space is at a premium, such as in mobile devices and laptop computers.

The FMMD914TA is used in these applications due to its superior performance when compared to traditional silicon-based rectifiers. Its reverse-recovery time is much faster than that of a silicon-based rectifier, resulting in better performance and improved reliability. Additionally, its low profile enables it to be used in more compact designs.

The working principle of the FMMD914TA is fairly simple. When a voltage is applied across its terminals, the diode will conduct current in the forward direction and block current in the reverse direction. This prevents the current from increasing to dangerous levels, while allowing the device to draw only the desired amount of current. In this way, the diode can be used to control the amount of power flowing through a circuit.

The FMMD914TA is a versatile and reliable rectifier, suitable for use in a variety of applications. Its superior reverse-recovery time makes it particularly well-suited for high-frequency applications, while its low profile makes it a good choice for applications where space is at a premium. As such, it is a popular choice for use in automotive and industrial applications.
