TVSs, or Transient Voltage Suppressors, are commonly used in circuit boards for overvoltage and transient protection. They are a low cost, reliable form of circuit protection, and are available in a wide variety of different packages. The SMAJ10HE3/61 TVS is a popular choice for television and other consumer electronics applications due to its low cost and small size.

Features

The SMAJ10HE3/61 TVS is a unidirectional device, meaning it will only protect against current flowing in one direction. It has an epoxy resin body, which is much more durable than the metal bodies of other TVS. It also has a current rating of up to 10 Amps, and a response time of less than 5 nanoseconds, which is incredibly fast compared to other TVSs. Additionally, the SMAJ10HE3/61 offers a clamping voltage of 61V, which means it can protect against higher voltages than typical TVSs.

Applications

The SMAJ10HE3/61 is most commonly used in television applications, such as cable, satellite, and digital TV receivers. It is also used in video game systems and other consumer electronics. Along with its small size and low cost, the SMAJ10HE3/61 makes it an ideal choice for these kinds of applications. It is also used in telecommunications equipment, such as telephony and data transfer systems. The SMAJ10HE3/61 was also designed for automotive applications, but its size and cost make it less suitable for this application than many other TVSs.

Working Principle

The SMAJ10HE3/61 uses a semiconductor diode to protect against overvoltages and transients. When an overvoltage occurs, the diode conducts current, allowing the excess energy to be safely discharged into the circuit. The diode is connected between the line and ground, with a zener diode connected in series to ensure the diode is properly biased. When the diode conducts, the zener diode provides a voltage drop across the diode, which prevents further conduction. This prevents the voltage from exceeding the diode\'s saturation voltage, and protects the circuit from damage.

Conclusion

The SMAJ10HE3/61 is a popular choice for television and other consumer electronics applications, due to its low cost and small size. Its unidirectional design, 10 Amp current rating, and fast response time make it a great choice for these types of applications. Additionally, its clamping voltage of 61V protects against higher voltages than typical TVSs. Finally, its working principle of using a semiconductor diode to protect against overvoltages and transients ensures it can provide reliable protection.
