P4SMA10A R3G Circuit Protection

TVS - Diodes are widely used in various fields, such as ESD protection, signal protection, and data line protection. The P4SMA10A R3G is a unidirectional TVS Diode which use internally-thermally-enhanced technology to increase protection level. It is rated at 10A peak current with 3.3V voltage standoff. They have an industry-standard SMB foot-print and it is RoHS compliant, MATTE finish, MSL1 compliant.

In the application field, P4SMA10A R3G can be used in USB power supplies, modems, routers, cable extenders, power converters, and other interfaces with 3.3V voltage standoff. They can also be used in isolated DC/DC converters, game consoles, telecom line cards and many other protection circuits. The working frequency range of this TVS diode is up to 1GHz, making it ideal for high-speed data line protection.

The principle of P4SMA10A R3G TVS diode is quite simple. Its internal diode structure will turn on when transient voltage exceeds its breakdown voltage level, thus diverting the transient energy away from the sensitive electronic components. As a result, the device can offer peak pulse current up to 10A and clamping voltage of 40V. It has very low leakage current as well as consistently low capacitance.

This device is built to meet application requirements such as IEC 61000-4-2 and RoHS compliance. It has integrated thermal withstand capability thanks to the Insulated Gate Bipolar Transistor (IGBT) structure, which allows it to operate safely up to floor-plate temperatures of 150°C. P4SMA10A R3G has a very low clamping voltage, which means that it can provide the required level of protection even in high-speed switching applications.

P4SMA10A R3G is suitable for applications where small size and high peak pulse current are necessary. This device is robust enough to handle up to 10A peak current surges, providing additional layer of protection for sensitive components in various applications. As well as offering high peak current capability, P4SMA10A R3G also has very low capacitance, leakage current, and clamping voltage. These features make P4SMA10A R3G an excellent choice for high-speed data line protection.
