The P4SMA100A-E3/61 is a unidirectional high-speed switching diode that is available in the card-edge S®M(DO-214AC) package. It stands for the Principle 4 Semiconductor device designation - Medium Power Standard Avalanche Rectifier, 100 Ampere maximum average output current, A suffix for some additional feature, E3 means the rating of the operating junction temperature and 61 is the date inventory code. When considering packaging options, the DO-214AC card-edge S®M package makes it easier for the user and provides circuit protection with its power dissipation capabilities.

The P4SMA100A-E3/61 diode is suited for use in switching application and typically used for protection circuits, such as TVS (transient voltage suppressor) diodes. It is designed with a built-in avalanche diode that allows these diodes to clamp transient voltages and protect the circuits, requiring no additional external components. It has a maximum operating temperature rating of +125ºC ideal for high-temperature, lead-less applications. These transient voltage suppressors are also suitable for a wide range of applications, including power supplies, motor drives, power circuitry, and computer equipment.

The P4SMA100A-E3/61 has a guaranteed breakdown voltage of up to 100V. It’s fast switching capabilities supports the protection of circuits from high voltage transients. Its very fast response time and high peak current capability can absorb transients of all widths. It is compliant to the requirements of E-marked Europe. It has a maximum peak pulse power rating of 400 W.

The working principle of the P4SMA100A-E3/61 is rather simple. When exposed to reverse bias at a low voltage, the device does not conduct. When a higher voltage is applied, which is called the breakdown voltage, the device conducts and the current is limited by an integrated avalanche effect. This process helps to protect circuits or devices from transients that might damage them otherwise. The integrated avalanche diode allows for fast and high-current clamping of transient voltages. The integrated avalanche effect also helps to reduce any resistive losses in the diode.

Since the P4SMA100A-E3/61 can respond quickly to transients, it\'s suitable for use in a variety of outdoor or indoor environments. This includes industrial, commercial, consumer and medical applications. Furthermore, its reliability enables it to be used in applications where failure is not an option, such as automotive electronics, telecommunications, military, aerospace and other mission critical systems.

In summary, the P4SMA100A-E3/61 diode is a versatile, unidirectional high-speed switching diode that provides fast response and high-current clamping of transient voltages. It is characterized by its high reliability and is suitable for use in a wide range of applications, including power supplies, motor drives, power circuitry, and computer equipment. Additionally, this diode\'s built-in avalanche diode allows it to clamp transient voltages while requiring no additional external components.
