1.5SMC16A-E3/9AT

TVS diodes protect sensitive electronics from high-voltage electrical transients and ESD events. 1.5SMC16A-E3/9AT is another type of transient voltage suppressor designed and constructed to maximize ESD protection for sensitive systems, specifically for computer system or data communication applications.

Application Field

1.5SMC16A-E3/9AT TVS(Transient Voltage Suppressor) diode is suitable for high-speed data line protection. It offers a 600W peak pulse power capability at 1.5/50us wave form, a working voltage range of 6.5V - 300V, and a reversible maximum peak pulse voltage of 600V and maximum reverse voltage up to 300V. This diode requires no external components and can reliably protect one or more signal lines from high-energy surge events.

This TVS diode is also applicable for RS232, LAN, SCSI, HDC, MODEM, TELCO and video devices, or for any other applications requiring protection from ESD, electrical overstress (EOS) and lightning-induced transients. Its low capacitance enables it to provide fast response time that can help reduce the amount of surge current and clamping voltage to acceptable levels.

Working Principle

The 1.5SMC16A-E3/9AT TVS diode utilizes a special construction that enforces a double-diode effect in a single package. It works by absorbing large surge current and clamping the voltage spike across the protected line. When the ESD event occurs, the device acts like a short circuit and the current is conducted through the diode. This causes the voltage to drop quickly and when the peak voltage is reached, the current abates accordingly.

This device is designed to withstand multiple high-voltage pulses and it contributes very little capacitance and inductance to the circuit. This helps maintain low levels of signal attenuation and ensures that the signal remains clean and unaffected. Additionally, the LED indicator on this TVS diode helps to monitor its status of operation.

In conclusion, 1.5SMC16A-E3/9AT TVS diode provides superior protection for sensitive systems from surge events. With its compact design and fast response time, it can help protect various types of components and devices from various types of ESD, EOS and lightning-induced transient voltage spikes.
