3KASMC18HE3_A/I

3KASMC18HE3_A/I is a device classified as a unidirectional transient voltage suppressor (TVS) diode. It is designed to protect against voltage and current surges in electronic devices, such as automobiles, home appliances, and computers. It is an ideal solution for reducing system downtime due to over-voltage or over-current conditions.

The 3KASMC18HE3_A/I combines a MOSFET (metal-oxide-semiconductor field-effect transistor) with an avalanche diode in a single-package. It is specifically designed to provide protection from over-voltage and over-current conditions in DC applications, such as those used in automotive and consumer electronics. The device is designed to offer excellent electro-thermal performance in a compact footprint, and is RoHS compliant.

The working principle of the 3KASMC18HE3_A/I is quite simple. It consists of a MOSFET connected to the positive line and an avalanche diode connected to the negative line. The MOSFET has a threshold voltage and any voltage above this threshold triggers the MOSFET to conduct. This triggers the avalanche diode, which then conducts a surge current around the protection circuit, thus protecting the circuit from overload.

The 3KASMC18HE3_A/I also provides an isolation barrier to prevent noise and transient voltage signals from passing through the device. This helps to prevent damage to the delicate electronic components from excessive voltage or current surges. The device also reduces EMI (electromagnetic interference) as it is designed to reject external EMI signals.

The 3KASMC18HE3_A/I can be used in a variety of applications such as automotive, consumer electronics, communications, and industrial applications. It can be used as a lightning or surge suppressor, as well as in other applications where protection from transient voltage surges is required. Additionally, the device is designed to operate in extreme temperature ranges, making it suitable for use in a variety of applications.

The 3KASMC18HE3_A/I is a unique and useful device which offers protection from over-voltage and over-current conditions in a compact package. It offers excellent electro-thermal performance and provides an isolation barrier to prevent noise and transient voltage signals from passing through the device. It is a great cost-effective solution for reducing system downtime due to over-voltage or over-current conditions.
