TVS (Transient Voltage Suppression) diodes are devices used to provide protection against electrical transients or electromagnetic pulses that could damage sensitive elements in electronic and electrical circuits. SMDA15.T is a part of the transient voltage suppressor (TVS) diode family, introduced by Diodes Incorporated. It is designed to protect sensitive electronics from overvoltage damage that may result from ESD (electrostatic discharge) or power cross testing.

SMDA15.T is a five-pin, low-capacitance, ultra-high-speed TVS diode offering. Featuring an ultra-small form factor, this device is well suited for applications requiring board area saving. Rated at 15 Volt working voltage, it is capable of providing ESD and transient overvoltage protection up to 25kW. It is also well suited for protecting signal lines in high-speed IC circuits such as LCD displays, digital cameras, and mobile devices.

SMDA15.T is designed to quickly respond to transient overvoltage, typically below 1 nanosecond. Its ultra-low capacitance values make it well-suited for utilization in high-speed signal and data line protection. The TVS diode absorbs overvoltage above the clamping voltage and will conduct a defined amount of current due to its conduction losses. This feature serves to clamp and suppress voltage transients, providing a safe operating environment for other sensitive components in the circuits.

The device has an integrated series resistance that ensures low clamping voltages, providing optimal levels of protection for low and medium power applications. Unlike a traditional Zener diode, SMDA15.T is a non-linear device that can handle higher ESD and transient voltage levels than conventional Zener diodes.

SMDA15.T is also designed to handle lead-free reflow soldering processes, having a maximum temperature of 260°C for up to 10 seconds. It is designed to work in temperatures ranging from –40°C to +125°C, making it a perfect choice for portable, consumer and industrial applications.

SMDA15.T is quickly becoming a popular choice for ESD protection in the growing consumer electronics industry. Its lightweight, small form factor, low-capacitance and high-speed response time make it well suited for use in a wide range of applications. With its robust design and reliable protection capabilities, SMDA15.T is well-suited for working with sensitive electronics such as mobile devices, laptops, tablets, and HDDs.
