SZSL05T1G

TVS (Transient Voltage Suppressors or Transient Voltage Suppressor)—also known as surge suppressors—are semiconductor devices that protect electrical systems from high voltages. TVS diodes, specifically, are electrical components capable of providing protection from high-energy voltage and current transients, which are commonly caused by electrical phenomena such as lightning, power surges, and electrostatic discharge (ESD).

SZSL05T1G is a TVS diode designed to protect against overvoltage spikes and transients. It is a unidirectional device commonly used to protect circuits such as I/O ports, data/communications lines, and low-power AC line inputs. The diode features a low reverse leakage, fast response time, and a high peak pulse power rating, making it suitable for various applications.

Application Field

SZSL05T1G is optimized for applications such as low capacitance interference protection and power supply ESD protection. It is also suitable for surge and high voltage protection, damping an overvoltage condition on AC mains inputs, automotive systems, and cell phone charging systems. It is also well suited for LED protection and destruction prevention in applications such as digital cameras, computer peripheral systems, and in solar gardens.

Working Principle

SZSL05T1G works by using the avalanche breakdown voltage of an N-channel MOSFET and a high voltage Thyristor to limit overvoltage. When the voltage input to the diode exceeds the limit, a fast current pulse is generated that causes the diode to switch off. This helps protect sensitive electronic components from being destroyed due to a voltage spike or transient.

The diode also features a unique self-restoring mechanism that allows it to restore normal operating conditions following a high voltage spike or transient. This restores normal circuit operation without having to manually reset the diode.

The TVS diode also incorporates a ‘soft-clamp’ feature that ensures that the actual voltage clamping process is smooth. This helps minimize power dissipation, heat generation, and other unintended consequences associated with voltage spikes and transients.

In short, SZSL05T1G is a highly efficient, cost-effective TVS diode designed to protect vulnerable circuits from voltage transients and spikes. It features a low reverse leakage, fast response time, and a high peak pulse power rating, making it suitable for a wide range of applications.
