MASMCJLCE8.0A – TVS – Diodes Application Field and Working Principle

The MASMCJLCE8.0A diode is part of the TVS family of diodes – specifically Transient Voltage Suppressors. A TVS diode is a unidirectional semiconductor component developed to protect electronics and hardware components from damaging voltage transients and induced surges – generally due to nearby lightning strikes. This type of diode is used to prevent overvoltage transients which could cause significant system damage or data loss.

The MASMCJLCE8.0A diode is a long-term, 8 kV, 33 nS, compliant TVS diode that is designed to offer long lifetime performance with exceptional surge capability. This component is designed to provide protection from 8 kV surge transients at rated standoff voltages of 5.0 V peak, 20 A peak. When exposed to transients, the diode will respond by reducing the voltage on the downstream system component, preventing potential damage.

Functionality and Operation

The MASMCJLCE8.0A diode operates by diverting current away from the protected equipment. Utilizing the common diode equation, when the transient voltage is greater than the diode’s breakover voltage (BoV), current will flow through the diode and the power can be dissipated into the environment. When not exposed to transient or surge current, or when the transient current is less than the breakover voltage, no current will flow through the diode, and the diode will have negligible impact on the system.

Applications

The primary use of the MASMCJLCE8.0A diode is as a surge and transient suppressor. Applications include automotive charging systems, personal computers, workstations, telecom equipment, and any other application where surge or transient protection is required. It is also ideal for applications where noise immunity from nearby lightning strikes is required for mission-critical systems.

Advantages

The MASMCJLCE8.0A diode is designed to offer long lifetime performance with exceptional surge capability. Its small footprint allows for more integration of protection circuitries within limited space. It provides protection against 8 kV surge transients and 20A peak current. It also provides wide temperature range protection from -55°C to 125°C.

Conclusion

The MASMCJLCE8.0A diode is an ideal choice for surge and transients protection, offering wide temperature protection, and exceptional surge capabilities. With its small footprint and superior design, it is highly suitable for mission-critical systems, personal computers, workstations, telecom equipment, and any other application where surge or transient protection is required.
