• TVS Diodes
• 1.5SMC39 Application Field and Working Principle

TVS (Transient Voltage Suppressor) Diodes are used to protect against electrostatic discharges (ESDs), electrical overstress (EOS) and [electrically fast] transients, as well as the short-term overvoltages caused by lightning, switchgear and industrial equipment. These devices were designed to protect vulnerable components such as memories, sensitive ICs and etc from a transient voltage surge that is greater than what the particular device can handle due to its power rating.

1.5SMC39 is a common TVS Diode that is used to protect against transient voltages. It is a unidirectional, two-pin device featuring a low capacitance (6-17pf) of ~6pF. The TVS Diode features a typical breakdown voltage of 38.7/41.3V, and a hold-over voltage of 19.4/20.7V. The maximum peak pulse power is 1500W, while the maximum peak pulse current is 200A peak for 1us. The device includes an internal switch to control the voltage.

The 1.5SMC39 is commonly used for 4.5kV protection with a surge rating of 1kV/ms. It can also offer over voltage protection and stabilize line voltage. It is typically applied in telecommunications, computer and industrial equipment. In addition, the device can be used in power supplies, motion control systems, motors, lighting systems and industrial automation equipment.

The working principle of the 1.5SMC39 is quite simple. The diode has two pins, an anode and a cathode. When a voltage greater than the breakdown voltage is applied between the two pins, the device switches on and begins to conduct. This allows a current to flow and the energy stored in the electric field is dissipated through the diode. When the voltage falls below the breakdown voltage, the device switches off, stopping any further current flow.

In conclusion, the 1.5SMC39 is a type of TVS Diode that provides protection against transient voltages. It is commonly used in a variety of applications including telecommunications, computer and industrial equipment. The device has a breakdown voltage of 38.7/41.3V and a hold-over voltage of 19.4/20.7V, and features an internal switch to control the voltage. It can offer protection against 4.5kV with a surge rating of 1kV/ms, and the working principle of the device is quite simple.
