Transient voltage suppressors (TVS) are a type of diode that provides fast-acting protection against voltage transients that may exceed the IC’s rated operating voltage. The SMA5J26-E3/61 TVS diode is specifically designed to protect a variety of analog and digital electronics from overvoltage damage, and it is protected against surge and protection circuit activation.

Application field of SMA5J26-E3/61 TVS diode

As stated earlier, SMA5J26-E3/61 TVS diodes are designed to protect various electronics from damaging overvoltage transients. Typically, these transients appear as high-energy pulses that can drive a wide range of currents (up to 36 A @ 820 us) and lead to the destruction of the circuitry that it is protecting. Some of the most common applications of SMA5J26-E3/61 include:

• Computer Peripherals
• Automotive Circuits
• Communication Systems
• Industrial Automation
• Data Processing Systems
• Consumer Electronics

The SMA5J26-E3/61 TVS diode is also well-suited for other applications involving a broad range of frequencies and operating voltages.

Working principle of SMA5J26-E3/61 TVS diode

SMA5J26-E3/61 TVS diodes employ advanced avalanche junction technology to ensure the highest level of protection against high-energy transients. This technology utilizes a special isothermal configuration to control the level of energy stored in the diode. The diode has a threshold voltage, or trigger voltage, and will only activate when the voltage exceeds this threshold. Once this threshold is surpassed, the diode begins to switch on, redirecting the excess energy from the circuit it is protecting.

The SMA5J26-E3/61 TVS diode also features a built-in protection circuit that is designed to ensure that the diode does not get damaged by the surge. This protection circuit automatically discharges the diode after the transient has dissipated. This allows the diode to be used in high voltage or high current environments, ensuring that it does not get overworked and damaged.

The other main feature of the SMA5J26-E3/61 TVS diode is its very fast response time. This response time is typically in the range of 8 to 20 nanoseconds, and allows the diode to react quickly to any overvoltage transients. This ensures that the circuit it is protecting is not subjected to any prolonged exposure to the damaging transients.

Conclusion

The SMA5J26-E3/61 TVS diode is an invaluable tool for protecting a variety of electronic equipment from overvoltage damage. Its fast-acting protection, coupled with its integrated protection circuit and high-energy threshold voltage, makes it exceptionally well-suited for a broad range of industries and applications. As such, it is an essential part of any circuit protection regimen.
