TVS (Transient Voltage Suppressor) diodes are semiconductor-based components featuring a reverse breakdown voltage and a specified peak surge current capacity; these components are designed to protect sensitive devices against catastrophic overvoltages. 3KASMC14AHM3_A/H diodes are designed to protect automotive applications against surge voltages, and to prevent severe damage to the device due to an unexpected power spike.

3KASMC14AHM3_A/H diodes are designed for harsh automotive environments and are compliant with AEC-Q101 standards. The fast response time of these diodes helps protect against circuit-damaging high-energy pulses resulting from inductive transients, and the AEC-Q101 qualification ensures that the diodes can withstand temperature extremes, humidity, and exposure to oil and other harsh fluids.

The working principle of the 3KASMC14AHM3_A/H diode is based on the principle of the PN junction. When the voltage across the junction exceeds the reverse breakdown voltage, current flows through the junction via avalanche breakdown, allowing current to continue to flow until the overvoltage is removed. This provides reliable protection against voltage spikes in the automotive environment.

The 3KASMC14AHM3_A/H diodes have a peak pulse current rating of 14A, with a breakdown voltage range of 6.5-12V. The response time of these diodes is <1µs, and the maximum operating temperature is 175°C. The diodes are available in through-hole and surface mount packages.

3KASMC14AHM3_A/H diodes are suitable for protecting automotive applications against electrical transients and overvoltages, and provide reliable protection for circuits from transient surges. The built-in protection features of these diodes ensure that devices are protected against catastrophic failure due to power spikes or overvoltages. The AEC-Q101 qualification ensures that the diodes can withstand the rugged conditions found in automotive applications and protect sensitive components from damage.
