Transient Voltage Suppressor (TVS) Diodes have been a go-to solution for protecting sensitive electronic components from high voltage transients, such as lightning-induced, electrostatic discharge, power line, and over-voltage surges. The P4SMA350CA is a high voltage unidirectional silicon-avalanche transient suppressor - a type of TVS Diode. It has a breakdown voltage of 350V and a peak off-state power dissipation of 4W. This unit’s features, compatibility, structure, and applications make it ideal for a wide array of application fields.

The P4SMA350CA is status-quo in terms of its dimensions and outlook. It comes in a 0.20” x 0.20” SMT package, weighs just 0.13g, and can withstand a maximum temperature of +150°C. Thanks to its small size, it does not require any additional space or air for cooling. P4SMA350CA is also compatible with different semiconductor materials, such as Silicon, GaAs, and Silicon-Germanium. It performs particularly high in terms of surge energy, allowing for operations in harsh environments and applications with extreme transient voltages.

The P4SMA350CA uses avalanche breakdown for over-voltage protection. The intrinsic reverse breakdown voltage of silicon acquired through doping allows the P4SMA350CA to dynamically absorb and dissipate large amounts of energy, while still maintaining a precise reference voltage. The avalanche-clamping mechanism also makes sure that the breakdown voltage remains relatively stable, regardless of ambient temperature and thermal conditions. Furthermore, the P4SMA350CA can operate in the breakdown region for extended periods of time without any major performance issues.

The P4SMA350CA is an ideal choice for applications that require precise voltage protection, including automotive, consumer electronics, data/telecom, lighting, medical, desktop/portable/server power supplies, power converters, and power management in industrial and communications. Its broad compatibility also makes it perfect for different semiconductor materials, particularly for the protection of ICs and high-powered components.

To summarize, the P4SMA350CA Transient Voltage Suppressor Diode is the go-to choice for applications requiring precision voltage protection. Its small size, weight, and compatibility make it suitable for a wide range of applications, and its structure utilizes a reliable and stable avalanche breakdown mechanism for protecting against over-voltage surges and transients. As a result, P4SMA350CA is a popular choice for a variety of electronics applications.
