TVS - Diodes are components used to protect electrical systems from voltage and current spikes resulting from various sources, including lightning strikes or failure of an internal circuit. The VTVS15ASMF-HM3-18 is a Transient Voltage Suppressor Diode designed specifically for the automotive industry. It is typically used to suppress transient voltage spikes which may occur on 12V and 24VDC lines.

The VTVS15ASMF-HM3-18 is a dual in-line package (DIP) device featuring a surface mount with two separate packages. It is a unidirectional device with an operating temperature range from -40°C to +105°C and an operating voltage range of 6.0V to 18.0V. The device is composed of two silicon (Si) chips, a pair of end connection electrodes and a single body shell. The two Si chips are connected in series and share the common emitter junction. The end connection electrodes allow two devices to be connected in series on the same power line.

The VTVS15ASMF-HM3-18 is designed to protect automotive electronic circuits from transient voltage surges. It is ideal for use in applications where 12V and 24VDC lines are subject to rapid voltage variations. Examples include engine control units, lighting systems, communications systems, and power supply lines. It is also widely used in the automotive industry to protect the signal and power lines of a vehicular communication system from currents.

The VTVS15ASMF-HM3-18 works by providing a path for an overload current to bypass the protected circuit. The device is triggered by an excessive voltage on the power line. When triggered, it will redirect the overload current away from the protected lines, thus preventing damage. Depending on the application, the device can also be used to provide a measure of signal line protection. The device is designed to withstand a maximum surge current of20A.

The VTVS15ASMF-HM3-18 is a reliable and cost-effective solution for transient voltage protection. It features high performance and an extended operating temperature range, making it suitable for harsh environments. It is also RoHS compliant and UL recognized, making it an ideal choice for protecting automotive circuits from voltage spikes.

In summary, the VTVS15ASMF-HM3-18 is a Transient Voltage Suppressor Diode designed specifically for the automotive industry. It is typically used to suppress voltage spikes on 12V and 24VDC lines. The device works by providing a path for an overload current to bypass the protected circuit. It is a reliable and cost-effective solution for transient voltage protection. It is also RoHS compliant and UL recognized, making it an ideal choice for protecting automotive circuits from voltage spikes.
