SA7.0CAHE3/73

The SA7.0CAHE3/73 is a TVS Diode, which stands for Transient Voltage Suppressor. It is a two terminal component that is used to protect electrical and electronic circuit from voltage spikes. The device is designed to clamp high voltages and instantly redirect the energy away from the electronics circuit used on the device.

The purpose of the TVS Diode is to detect rapidly escalating voltages and switch on as quickly as possible to shunt away the unexpected energy. The three key factors that affect the threshold levels of a TVS diode are peak pulse power, peak pulse current and Stand-off voltage. The peak pulse power is the maximum pulse energy the device can absorb before failing, peak pulse current is the energy needed for the device to activate and the Stand-off voltage is the clamping voltage or voltage breakdown required for the device to activate.

The SA7.0CAHE3/73 is a surface mount diode, designed for medium surge suppression applications in low-capacitance, low-power applications. It has a low stand-off voltage of 7V and can handle peak pulse power of 1500 Watts. It can handle peak pulse currents of up to 300 Amps with a broad 600A surge withstand ability.

The SA7.0CAHE3/73 PolySwitch device operates on the reverse conduction principle of a diode to act as a highspeed switch. When triggered by an input voltage exceeding the device´s specified level, breakdown occurs and the diode conducts current. The diode´s internal shunt function shunts the current away from the circuit, thereby preventing damage.

The SA7.0CAHE3/73 device is suitable for use in automotive applications. Its stand-off voltage is also suitable for use with alternator systems, and its ability to withstand very high peak pulse power makes it ideal for controlling engine noise. It can also be used for a range of applications such as USB data lines, phone lines, and household lighting to name a few.

The SA7.0CAHE3/73 device is a highly effective and cost-efficient solution for protecting a wide range of applications from the damaging effects of electric shock, voltage transients, and static discharge. Its robust design makes it a reliable solution, withstanding up to 600 A surge current and 1500W peak pulse power. It is also a low-capacitance device, meaning it can be used in sensitive analog circuits without introducing excessive noise or distortion.
