High Surge High Voltage Ceramic Transient Voltage Suppressors 3225 MLV Chip Multilayer Varistors MVR1210-431G 1210 431V

Description

Multilayer Chip Varistors (MLV) are Transient Voltage Suppressors (TVS) which manufactured from semicon ductingceramics by the highly advanced multilayer formation technologies, which can offer rugged protection, excellent transient energy absorption and internal heat dissipation. The devices are leadless chip form, eliminating lead inductance and guaranteeing a faster speed of response time of less than 0.5ns, which makes the m fast enough to ensure reliable protection against ESD pulse and other specific transient events. These transient suppression devices are significantly smaller footprints and lower profiles than traditional zener diodes or radial MOVs.

Information for Designer

When selecting the TVS for designing within the circuit, some characteristic parameter should be considered carefully to meet the circuit condition. The following guideline are recommended.

1. The surge handling ability of the selected TVS should meet the need of dissipating the expected transient surge current of the protected circuit.

2. The clamping voltage of the selected TVS should be less than the maximum allowed operating voltage of the protected circuit.

3. In high speed data transmission situation. the capacitance of the selected TVS should be considered.

4. The special requests of the TVS’s capacitance such as ESD prevention are available, please contact with us.

5. While choosing the TVS, the working voltage of the TVS should be greater than or equal to the normal operating voltage of the circuit.

6. Protection Principle : When the voltage increase above the threshold of the varistor, the suppressor draws a rapidly increasing current. The the overvoltage is considerably attenuated.
