TVS – Diodes are components designed to offer over-current and over-voltage protection. They protect sensitive electronic components, mainly, by clamping voltage levels below a certain level to prevent damage from over-voltages. TVS – Diodes have become increasingly popular in the last few decades as they offer a higher degree of protection and more flexibility than traditional components like flyback diodes, metal-oxide varistors (MOVs) and fuses. The ATV15C750JB-HF is a back-to-back, high-speed, dual-channel bidirectional transient voltage suppressor (TVS) diode.

The ATV15C750JB-HF offers a broad range of protection from over-voltage levels between +50V to –37V. Its total power dissipation is rated at 600 W (t P ) and it is capable of handling surge currents up to 2kA, making it suitable for a wide range of applications. The component is also fast responding, with a typical clamping voltage of –40.2V for a 5kA 8/20µs pulse, and a typical turn-on time of 2.8ns.

The ATV15C750JB-HF is primarily designed for high-speed applications, such as data and signal protection, in which the component needs to respond rapidly to over-voltage conditions. It is also capable of providing accurate temporary voltage clamping and high ESD immunity for opto-coupled isolators, Ethernet, modem, and telecom interface circuits. The ATV15C750JB-HF may also be used in automotive systems, industrial circuit protection, and consumer systems that require better protection against sudden electrical transients.

The ATV15C750JB-HF employs back-to-back Transient Voltage Suppressor (TVS) diodes, which are connected in series with a common anode on one end. In normal operation, each diode has ideal reverse characteristics, blocking any negative voltage applied to them from the anode. However, when the transient voltage exceeds the Reverse Stand-off Voltage (V R(WM) ), the diode enters into the avalanche region, becoming a very low impedance and allowing current to flow.

This action prevents the voltage at the anode from rising any higher and clamping it to the avalanche voltage level. The ATV15C750JB-HF is also designed with a low leakage current of just 0.2 μA, which ensures that the device does not drain energy even when the application is powered on. This feature makes the ATV15C750JB-HF an ideal choice for low power applications, such as portable and consumer electronics.

The ATV15C750JB-HF is perfect for a wide range of applications, from industrial to consumer electronics. It is an ideal choice for systems that require fast responding and reliable protection from over-voltages. Its low leakage current and wide operating range further add to its usability and make the ATV15C750JB-HF an excellent solution for a variety of protection needs.
