SMCJ16CAHE3/9AT Circuit Protection

Transient Voltage Suppression (TVS) is a type of protection device that is designed to tolerate or clamp surges and spikes in the voltage across its terminals. SMCJ16CAHE3/9AT is a TVS diode specifically programmed for automotive applications. It is designed with a low reverse leakage current, low capacitance, low-power dissipation, and low clamping voltage.

SMCJ16CAHE3/9AT is an Automotive-grade TVS diode that is used for protecting vehicles from electrostatic discharge (ESD) or transients, even in extreme harsh environments. This component has an operational temperature range of -55°C to +150°C and a storage temperature of -55°C to +175°C. Its 15kV IEC test current and an 8/20µs surge can provide reliable over-voltage protection.

SMCJ16CAHE3/9AT works by clamping surges and spikes to the maximum voltage rating. It also prevents excessive current, making sure that the voltage does not exceed the maximum voltage. The transient voltage suppression diode connects between the power supply rail or signal line and ground. As soon as the voltage reaches its peak, the diode starts to conduct current through its junction. This helps reduce the voltage to safe levels.

SMCJ16CAHE3/9AT TVS Diodes can be used in various automotive applications, including airbag systems, smart keys, Infotainment systems, and TPMS. They can also be used in communication systems, such as Base transceiver stations, PoE, GPRS, Wi-Fi, and Bluetooth. It is an excellent choice for power surge, ESD, clamping, and load switch protection in harsh automotive engine environments.

The SMCJ16CAHE3/9AT TVS diode is a three-terminal device constructed with high-efficiency PN junction diodes. The anode and cathode are connected internally, and the three terminals of the diode are connected with an external circuit. The anode is the positive terminal and the cathode is the negative terminal. The middle terminal is the gate. When a surge occurs, an internal voltage difference is generated between the anode and the cathode, which triggers electron transition to occur between the anode and the cathode.

SMCJ16CAHE3/9AT TVS Diodes demonstrate high ESD immunity and damping characteristics, enabling the protection of equipment from high-voltage surges and other transient events. They also feature fast response and clamping times, and offer excellent surge protection performance up to 15kV. Additionally, they are designed to meet the IEC 61000-4-2 Level 4 standard.

SMCJ16CAHE3/9AT TVS Diodes are designed to provide superior protection in various automotive applications. They are capable of suppressing surges and spikes in the voltage, allowing greater levels of protection than traditional fuses or circuit breakers. With their low capacitance, low-power dissipation, and robust design, these components are an essential part of automotive electronic systems.
