TVS diodes or transient voltage suppressors (TVS) have become increasingly important circuit protection components due to their ability to limit transient voltages in a variety of applications. TVS diodes are designed to protect vulnerable circuits from voltage transients caused by electrostatic discharge (ESD) and electrical fast transients (EFT).

The MPLAD36KP48CAE3 (MPLAD36KP48CAE3) is a micro-power unidirectional TVS (transient voltage suppressor) diode designed to protect delicate low-voltage systems, such as PCMCIA, ISP, or cellular phone, due to the increased demand for portable products. This TVS diode offers optimized ESD protection and is characterized for low leakage, clamping voltage and high surge capability.

Application Field and Working Principle:

The MPLAD36KP48CAE3 is suitable as ESD protection in a wide range of applications, including portable electronics, automotive systems, consumer products, and industrial systems. It is suitable for use on printed circuit boards. The TVS diode provides protection against lightning surge, as well as EMI/RFI noise. It helps to protect circuits from high energy transients, enabling circuit protection as well as compliance with limits for IEC 61000-4-2, Level 4 (ESD) and IEC 61000-4-4 (EFT) for transient curves.

The MPLAD36KP48CAE3 is a Micro-Power Transient Voltage Suppressor (TVS) Diode that offers optimized ESD and EFT protection and features low leakage current, low clamping voltage and a high surge capability. Operated in unidirectional mode, the device offers maximum protection by clamping the voltage transient to a safe level. It is characterized to meet requirements for the IEC61000-4-2 and IEC61000-4-4 standards.

The MPLAD36KP48CAE3 is based on a silicon avalanche diode that is held in the reverse biased condition. When a voltage transient strikes the diode, the current through the diode rapidly increases, creating a heavily doped region in the silicon PN junction. This causes the voltage to fall to the peak avalanche voltage of the diode. The device normally operates in the reverse direction, so that the avalanche diode becomes a low voltage–high current path.

In order to ensure an adequate protection level the MPLAD36KP48CAE3 devices offer a high ESD protection rating that is based on the IEC 61000-4-2 Air Discharge (Level 4) standard. The operating voltage of the device is typically about 10–20 volts, so it can withstand high transient voltages up to about 70 volts. The leakage current is also low, typically below 10 µA, so it does not introduce any additional power losses in the circuit.

The MPLAD36KP48CAE3 provides surge protection with low clamping voltage. The peak pulse current capability is 800 A, making it suitable for high power applications. The device has a low capacitance of 0.3 pF, allowing it to provide a good response time. The diode normally remains in the reverse bias condition at normal operating voltages prior to the occurrence of the transient event, so it does not affect the normal operation of the circuit.

The MPLAD36KP48CAE3 is an ideal choice for applications where ESD protection is required. It provides a cost-effective solution for protection of sensitive electronic circuits, such as data lines and power sources, from destructive voltage transients. The device is easy to install and its low parasitic capacitance allows for faster response times for transient protection.
