ESDA14V2SC6

Introduction

ESDA14V2SC6 is a small footprint automotive discrete Transient Voltage Suppressor (TVS) diode that is designed to provide protection from destructive voltage transients for automotive ICs and circuits. This TVS diode is a monolithic, bidirectional, low capacitance, low-leakage, and high-speed device that is offered in a space-saving state-of-the-art SC-59/SC-75 package. The ESDA14V2SC6 device features a low-capacitance of 6 pF, high-voltage rating of 20V, high-speed flow-through architecture, and an ultra-low working voltage. Its bidirectional construction ensures it is able to protect both the high-side and low-side of the circuit from negative and positive over-voltage transients, respectively. The robust construction of the device enables it to withstand up to an 8 kV peak Human Body Model (HBM) and the capability to handle up to an 18 A surge current.

Application fields and working principle

The ESDA14V2SC6 TVS diode is typically used in a wide range of automotive applications such as powertrain, body electronics, safety systems, infotainment and telematics. Specifically, it can be used to protect voltage-sensitive ICs that may be exposed to power line transients or automotive load dump. It is also suitable for ultra-low working voltage applications and to prevent ground bounce issues in high-speed data-lines. The working principle of the ESDA14V2SC6 TVS diode works in the following way. When the transient voltage rises beyond the device\'s clamping voltage, the diode will instantly clamp the voltage to a safe level. This is achieved by redirecting the transient current in the opposite direction such that it is dissipated through the TVS diode, minimising damage to the protected circuit. In addition to this, the low-capacitance of the device ensures that the signal integrity of the protected data lines is maintained.

Conclusion

The ESDA14V2SC6 device is a state-of-the-art automotive TVS diode that offers superior protection from voltage transients and surge currents. This device is offered in a small footprint package and is suitable for a wide range of automotive applications. Its demonstrated working principle and low-capacitance of 6 pF ensures it can provide reliable protection while maintaining the signal integrity of the protected circuit.
