TVS diodes, or Transient Voltage Suppressors (TVSs), are a vital component in order to protect circuits from damage caused by overvoltage. The SMCJ36A R7G is a variant of the TVS diode family that is designed for general purpose protecting the power supply against high voltage transients. This device has an extended lead frame which helps match the inductance of the PCB for fast response to surges and transients.

SMCJ36A R7G Application Field

SMCJ36A R7G is designed to handle high-level, high-repetition rate transient voltages and currents that can be caused by lightning, electromagnetic pulses (EMPs), or other similarly destructive events. It is often used in communication networks, aviation electronics, cars, and automotive equipment. Its primary application is protecting circuits from overvoltage, while its secondary application is protecting circuits from power surges. In addition, it can be used in power supplies, commercial appliances, and other industrial equipment.

Working Principle

SMCJ36A R7G TVS diode works on the same principle as other TVS diodes, rely on a semiconductor bridge (of either silicon or zinc-oxide) to detect an overvoltage and clamp it down to a safe level. When an overvoltage spike occurs, the TVS diode element starts to conduct and routes the excessive current through a bypass path. This limits the voltage to a safe range, and thus protecting the circuit from destructive overvoltages.

SMCJ36A R7G diodes are designed to respond quickly, meaning they can act in a microsecond or less in order to protect the system from potentially damaging electrical spikes. This makes them suitable for applications where there is a need to protect against short, high-amplitude transient surges.

The SMCJ36A R7G is available in a wide variety of package types to fit in any kind of application. Some of the package types available are Leadless Chip Carrier (LCC), Side-Winder (SW), Small Outline Package (SOP), and Pluggable Connector Modules (PCM). These packages provide a wide range of size options to fit any system needs.

Conclusion

The SMCJ36A R7G is an essential component in many modern electronics applications due to its ability to quickly detect and redirect overvoltage. It is available in a variety of small packages that can fit into tight spaces, making it a important part of the TVS diode family used for protecting circuits from damage caused by transient voltages or short high-amplitude surges.
