SMA5J16C-E3/5A is a unidirectional TVS diode, designed specially for protective circuit of electrical system in the context of overvoltage. It is especially designed to protect from the highest peak surge pulse voltage of 16A with a 10/1000μs waveform.

SMA5J16C-E3/5A is ideal for reducing the transients up to 5A current and ESD protection of storage equipment. Unlike ordinary silicone diodes, it features of highly reliable components and better performance. Moreover, SMA5J16C-E3/5A also enjoys features of low leakage current, low capacitance, low clamping voltage, fast response time, and good humidity resistance.

The application fields of SMA5J16C-E3/5A, includes such portable electronic equipment as notebook computers, calculators, digital cameras, smartphones, PDAs, accelerometers, 3G/4G wireless communication devices, GPS receiver and etc.

To better play its protection role, a surge absorber diode, such as SMA5J16C-E3/5A, is typically connected in parallel with the susceptible power or signal line. There is both an anode and a cathode in each TVS diode. Normally, the working principle is the same with any diode. When the voltage at the diode’s anode is higher than the voltage at its cathode, it will conduct normally, allowing the current to flow through. Otherwise, the current will not pass through, just like other diodes.

Unlike ordinary dissipation diode, the working principle of SMA5J16C-E3/5A is based on operating similar to that of a zener diode. It allows the current to pass from its anode to its cathode, as long as the voltage varying between its anode and cathode is lower than its clamping voltage. When the voltage is higher than this threshold, the diode will enter its zener breakdown region, and the excess energy will be converted into heat and thus their peak currents are limited.

SMA5J16C-E3/5A is an admirable choice for the need of peak pulse power protection. With its outstanding features like lightning protection, ESD protection, and overcurrent protection, it gives your electronic system better protection capability by sacrificing itself.
