SM12T1

Transient Voltage Suppression (TVS) Diodes provide superior protection against voltage transients caused by Electrostatic Discharge (ESD), Lightning Induced Surge, and other transient overloads. The SM12T1 is a Lower Capacitance Transient Voltage Suppressor with very low leakage current. It offers overvoltage protection for sensitive electronic components in the pipeline of communication equipment, such as Ethernet, Wireless, Internet of Things (IoT), Radio Frequency (RF), and Broadband access and/or home network.

The SM12T1 uses a silicon avalanche diode technology with a special guard ring structure that provides superior ESD protection up to 15kV, +/- 8kV of EFT protection, and 12V clamping voltage when a 0.25A surge (8/20µs) is applied. The device is able to withstand higher peak currents like those caused by Lightning Induced Surge. Its capacitance is extremely low at 0.15pF (typical), coupled with an ultra-low dynamic resistance of 0.1Ω (maximum). This low capacitance and dynamic resistance are optimal for preserving signal integrity.

The SM12T1 is housed in a SOD-323 package with a lead-free and RoHS compliant design. The housing provides excellent thermal performance with minimal thermal retardation for improved reliability. It also offers superior moisture protection in humid environments. The SM12T1 is suitable for a wide range of applications, such as power supply, DC/DC converters, ESD protection, surge current suppression, home networking and consumer electronics, automotive, and portable communication devices.

The SM12T1 provides high surge protection, ESD protection, and low capacitance, making it an ideal solution for a wide range of applications. The low capacitance design ensures signal integrity and noise immunity, while the low dynamic resistance ensures maximum clamping efficiency. Due to its small form factor, the SM12T1 can be easily implemented into designs. This device is RoHS compliant and lead-free, making it an ideal choice for applications that require minimal environmental impact.

In summary, the SM12T1 from Silergy Corporation is an ideal choice for a wide range of applications due to its low capacitance, low dynamic resistance, high surge protection, and ESD protection. Its small form factor makes it easy to implement in designs, while the RoHS compliant and lead-free design makes it an environmentally friendly solution.
