TVS - Varistors, MOVs

TVS (Transient Voltage Suppressor) devices provide overvoltage protection for systems by limiting associated voltage spikes. Commonly recognized forms of overvoltage protection include varistors, MOVs (Metal-Oxide Varistors) and silicon avalanche diodes (SADs).

BSPM1600TNR Application Field

The BSPM1600TNR is a TVS diode available in a Through-Hole package and provides overvoltage protection for a wide range of electronic equipment and systems. Its application fields include Automotive (In-Car Entertainment System, Automotive body control systems, OBD/ECS systems, etc.), Automated Optoelectronics (Link optical network systems, Telecom backbone and edge systems, Network communication equipments, etc.), Computers & Peripherals, Industrial Control (PLC, DCS, IAF, Digital Instrument Control, etc.), Network Equipment (Routers/Channel Bridges, HUB terminals, Modems, etc.), Consumer Electronic (Digital cameras, DVD players, Portable Business Machines, etc.), Power Supplies (AC Adapter, AC-DC power supplies for telecom/data and LCD panels, UPS, etc.), Medical Equipments (Ultrasound imaging, Pace-makers and other Cardiac Implantable Devices, MRI Systems, etc.).

BSPM1600TNR Working Principle

The BSPM1600TNR TVS diode is an integrated protection solution, consisting of a zener diode and two metal oxide varistors (MOVs). The two MOVs are the key components for suppressing transient overvoltages. They do this by utilizing an effect known as the “avalanche breakdown”, which happens when a strong electric field in a semiconductor material tears the bonds between atoms, causing electrons to be electrons to be swept away from their respective atoms and creates electron-hole pairs. This electron avalanche multiplication causes a large current flow in the material, resulting in a rapid drop in voltage along the material. By using MOVs, large ESD pulses can be clamped and dissipated without damaging connected electronics.The BSPM1600TNR also utilizes a built-in Zener diode to protect against lower level surge pulses. This device has an exponential breakdown characteristic which is designed to provide additional protection for lower levels of energy.

Conclusion

TVS (Transient Voltage Suppressor) devices are one of the most effective overvoltage protection solutions available and the BSPM1600TNR is a great choice for a wide range of applications. The device consists of two key elements, namely, a zener diode and two metal oxide varistors (MOVs). These two components work together to provide protection against both low and high level surge pulses, allowing for better protection from the damaging effects of transient voltages.
