Transient Voltage Suppression (TVS) diodes, also known as Transient Voltage Surge Supressors (TVSS), are a form of capacitor-diode-based solid-state protection device used to protect circuits from high voltage spikes or transients. The 3KASMC12AHM3_A/H is a low-capacitance, unidirectional Silicon TVS diode designed for general purpose Automotive ESD protection applications.
The 3KASMC12AHM3_A/H is designed to protect against electrostatic discharge (ESD) damage in automotive applications. It is packaged in the SOT-23-6 SMD package and offers superior ESD protection with its ultra low 3pF (max) capacitance. The device ensures high reliability due to its low clamping voltage, fast response time, and low leakage current. The diode is capable of absorbing up to 12 Amps of transient current and can withstand ESD testing up to 25KV (human body model) and 30KV (machine model). The device is ideally suited for automotive applications such as keyless entry systems, power seats, and airbag systems.
The working principle of the 3KASMC12AHM3_A/H is simple. It acts as a voltage clamp across a circuit. When the voltage across the TVS diode suddenly rises above the specified voltage, it becomes forward biased and starts to conduct current, which in turn prevents the voltage from getting too high. When the transient voltage has subsided, the diode regresses to its off state. This process helps ensure that the voltage across the circuit is well within the allowable range.
The 3KASMC12AHM3_A/H is specifically designed to provide ESD protection for sensitive components in automotive applications due to its low capacitance, fast response time, and low leakage current. It is capable of absorbing up to 12 Amps of transient current and can withstand ESD testing up to 25KV (human body model) and 30KV (machine model). With its wide operating temperature range (-40°C to +125°C) and robust package, the 3KASMC12AHM3_A/H is an ideal choice for a variety of automotive electronic applications.
