TVS diodes are becoming increasingly popular in the electronics industry due to their ability to protect sensitive electronic components from overvoltage, ESD, and EFT. The STIEC45-26ACS is a discrete negative transient voltage suppressor (TVS) that offers superior ESD protection up to 16kV human-body-model (HBM) protection, and up to 6kV Operating Constant Voltage (OCV). It also offers advanced low-capacitance (0.15 pF at 1.5kV) fast response, and low leakage current. The product is RoHS compliant, meets MIL-STD-202F and UL/CSA safety requirements, and is Approved by the Automotive Electronics Council (AEC Q101) for automotive application.

The STIEC45-26ACS can be used for a wide range of applications such as automotive electronics, automotive electronic control systems, as protection from ESD, EFT, and over-voltage transients in industrial control systems, power supplies, communication systems, and other sensitive applications. The device can also be used in surge protection circuits as a high frequency filter for power line disturbances.

The STIEC45-26ACS has a standard axial-lead, SOD-323 package that is suitable for reflow soldering. The device also offers a guarantee of low repetitive peak pulse current and high surge capability ensuring superior reliability. The device is constructed of polysilicon leads surrounded by epoxy resin and provides superior mechanical shock and vibration protection.

The basic working principle of the STIEC45-26ACS involves the use of a bidirectional Zener diode, in which a low voltage is applied across a Zener diode to form a Zener barrier. The Zener diode acts as a voltage limiter, preventing the voltage from exceeding the Zener barrier voltage. When a transient overvoltage appears at the input, the Zener diode limits the voltage to the Zener barrier value. The current then flows in the opposite direction, and is absorbed by the TVS diode, thus providing protection to the circuit.

The STIEC45-26ACS has been designed to provide excellent overvoltage protection, ESD protection, and EFT protection, in a wide variety of applications. The device is ideal for applications in automotive and industrial electronics, and offers superior protection against ESD, EFT, and over-voltage transients.

The STIEC45-26ACS offers superior performance with its low capacitance and fast response times ensuring protection from damaging overvoltage transients, safeguarding sensitive components and circuits against damage. The device is also RoHS compliant and compliant to safety requirements such as MIL-STD-202F and UL/CSA.
