Introduction: SMCJ78A V7G, which is also known as the “Unidirectional Transient Voltage Suppressor” (TVS–Diodes) is primarily used to protect your electric circuit or system from any kind of overvoltage and containing electronic parts.

Application Field: The main purpose of SMCJ78A V7G TVS-diodes is to provide overvoltage protection. It can be used in security systems, power supplies, communication systems, as well as in automotive and industrial applications. This one of a kind transient voltage suppressor can also be used to protect circuits from various kinds of electrical disturbances and surges including lightning, ESD (electrostatic discharge), and EFT (electrical fast transients). Its 400W capacity also makes it perfect for dealing with overvoltage and other abnormal voltage happenings.

Working Principle: This TVS-diode physically comprises of two or more diodes connected in parallel, in such a way that the first diode acts as a ‘clamping diode’ breaking the circuit on which it is connected and the second one as the ‘reverse diode’ forming the parasitic capacitance between itself and the junction of the first diode. This capacitance helps maintain the TVS-diode from exceeding their stated voltage rating by not allowing any excessive current to flow. The TVS-diodes also feature a Zener diode that is purposely designed to increase their energy absorption capability and short circuit withstand time.

Conclusion: The SMCJ78A V7G diodes are a great way to protect one’s circuit from overvoltage and other disturbances. Due to its 400W capacity, it is sure to protect any high powered device from surge elements over a wide range of operating temperatures. Thus, this TVS-diode may be the best solution for any individual looking for reliable protection.
