S23LC05TR

TVS or Transient Voltage Suppressor diodes are specially designed elements used to protect other electronic circuitry from high voltage. The S23LC05TR, is an example of a TVS diode, and is frequently used in various application fields due to its ability to handle transient voltage and provide fast circuit protection. In addition, it offers several other unique advantages, such as high reliability, low leakage current, and low thermal impedance.

The S23LC05TR is ideal for applications that require fast-responding protection against 230V transients such as cable TV, optical communication systems, and satellite receivers. It is designed for use in electronic equipment that requires protection for both data communication lines and power supply lines. The S23LC05TR is suitable for applications such as control boards, multimedia and satellite communications systems, home appliance electronics, and LAN/USB port protection.

The device consists of two diodes, one each for series and parallel protection. The series diode is responsible for clamping transients at a safe level, whereas the parallel protected diode is responsible for controlling the peak let-through energy of the transient. This ensures that the diode does not overstate or exceed its rated breakover voltage even under severe transient conditions. The breakover voltage of the device is typically between 150 and 250 volts.

The diode can withstand voltage transients up to 400V per second, providing fast-responding protection to the application circuit. It also offers a high peak pulse current of 1.5kA (8/20µs), with a typical reverse stand-off voltage of 80V, allowing for further flexibility in its application. The S23LC05TR also features a fast response time of less than 5 ns, meaning it quickly responds to a surge without allowing extensive damage to occur to the protected circuitry.

The device also features a low leakage current, meaning small amounts of current can flow through the device even when there is no transient voltage present. This helps protect the circuit from damage due to cumulative transient build-up. Additionally, the S23LC05TR has a low thermal impedance, meaning it is able to dissipate heat quickly and easily without causing the diode to fail due to overheating.

The S23LC05TR is a difficult to obtain device, mainly due to its unique design and fast-acting capabilities. However, it is commonly used in various fields due to its ability to protect a circuit against the most severe transient voltage. It is also ideal for prolonged protection in electronic equipment, where its low leakage current and thermal impedance are further advantages.
