TVS - Diodes: SA5.0CA B0G Application Field and Working Principle

Transient Voltage Suppressor (TVS) diodes are a class of fuses that provide overvoltage protection to a variety of electronic components. As such, TVS diodes are often called "transient voltage suppressor diodes" as their primary purpose is to prevent transient high voltage and current from damaging components. The SA5.0CA B0G is one such device.

Applications

The SA5.0CA B0G is used in a wide range of applications, such as cell phones, digital cameras, and DVD players. It is also used in automotive components, such as ignition systems, power windows, and electric brakes. Additional applications of the SA5.0CA B0G include audio and video electronics, circuit breakers, surge protection devices, power supplies, and motor control circuits.

Specifications

The SA5.0CA B0G is a part of the Littelfuse SA series of transzorbs. It has a voltage rating of 5.0 V, a maximum peak surge current rating of 30 A, and a holding voltage rating of 1.5 V. It is 0.130” (3.3 mm) in length and 0.041” (1.0 mm) in diameter. The SA5.0CA B0G is a bidirectional device, meaning that it is suitable for use in both forward and reverse polarization circuits.

Working Principle

The SA5.0CA B0G operates by clamping transient voltages that exceed its rated voltage. When the transient voltage reaches the rated voltage, the SA5.0CA B0G will reduce the voltage drop to a safe level, protecting the components of the circuit from damage. The SA5.0CA B0G is a bidirectional device, meaning that it is suitable for use in both forward and reverse polarization circuits. It is also able to protect components from both positive and negative transients.

Conclusion

The SA5.0CA B0G is a versatile device used in a variety of applications. It is a bidirectional TVS diode with a voltage rating of 5.0 V, a maximum peak surge current rating of 30 A, and a holding voltage rating of 1.5 V. The SA5.0CA B0G is able to reduce voltage drops to a safe level and protect components in both positive and negative transients, making it an ideal choice for a wide range of applications.
