TVS - Diodes have become an increasingly popular and useful form of transient protection over the last few decades. They have a wide variety of applications, ranging from overvoltage protection of telecom networks, circuit protection, and even EMI/RFI filtering. A key component of any effective overvoltage protection from surges, power transients, and lightning is a Transient Voltage Suppression (TVS) diode. The MAP5KE100CA is a high-performance, low-capacitance Transient Voltage Suppression (TVS) diode, which is ideal for a variety of sensitive electronic devices and systems.

The MAP5KE100CA is a unidirectional bi-directional hybrid protector that uses a unique combination of both Electro-Static Discharge (ESD) and Steering Diode protection. This hybrid design helps to protect circuits from the damaging affects of overvoltage transients and provides an extremely low level of capacitance while maintaining a very high level of surge current capability. In addition, it is designed with a high peak-pulse current rating of up to 12A, and is capable of withstanding surge events up to 1500W peak.

The primary application area for the MAP5KE100CA is in protection from sustained overvoltage transients and EMI/RFI noise. This device is used in a variety of audio-visual equipment, automotive, telecom and computer systems in order to protect against surges that may cause hardware damage or interfere with signal transmission. Its low capacitance prevents interference with sensitive communication lines, while its high-current rating ensures that it can handle larger transient events. In addition, the device is rated to withstand ESD in compliance with IEC 61000-2/EN 61000-4-2, making it ideal for consumer electronics protection.

The working principle of the MAP5KE100CA is that it behaves as a basic Zener diode when a voltage is applied to it above its breakdown voltage, also known as its avalanche or peak-pulse voltage rating. This causes the junction of the diode to break down, effectively clamping the voltage at the breakdown voltage. The voltage is then effectively “held” at this breakdown voltage until either the voltage dissipates or is discharged through the diode. This simple yet effective protection mechanism helps to keep sensitive electronic components from being damaged due to excessive voltages.

In conclusion, the MAP5KE100CA is a great choice for applications requiring protection from ESD, overvoltage transients and EMI/RFI noise. It offers an extremely low capacitance rating while still being capable of withstanding surge events up to 1500W peak. Its simple sub-microsecond clamping action protects sensitive electronic components from being damaged due to excessive voltages, while its high-current rating ensures that it can handle larger transient events. This makes it the perfect choice for a variety of sensitive electronic devices and systems.
