TTVS (Transient Voltage Suppressor) - Diodes are semiconductor devices that are used to safely channel large surges of electricity away from certain circuits. SP3130-01ETG TTVS diode is suitable for a wide range of applications. In this article we discuss the application field of SP3130-01ETG and its working principle.

The SP3130-01ETG is a uni-directional transient voltage suppressor (TTVS) diode which is designed for protection of sensitive electronics from overvoltage transients. The diode is capable of dissipating up to 1837 watts of energy per line for 8/20μs waveforms. It has an ultra-low 30mOhm typical dynamic impedance that helps limit the voltage during transients. The diode can be used in a variety of applications, including automotive electronics, consumer electronics, automotive sensors, and telecommunications.

The SP3130-01ETG TTVS diode features a breakdown voltage of 30V and a reverse breakdown voltage of 12V. The device is able to withstand high energy transients up to 65,000 watts. The device is dual polarity and has a peak voltage rating of 8.5V. It also has an operating temperature range of -55°C to +155°C and a storage temperature range of -60°C to +175°C.

The working principle of the SP3130-01ETG TTVS diode is based on the principle of transistor-like transistors. When a high voltage or surge passes through the diode, a large current flows through it and activates its built-in transistor. This causes the diode to act as an open switch, diverting the surge current away from the device or system that needs protection.

The SP3130-01ETG TTVS diode also has an ultra-low dynamic impedance. This helps reduce output voltage generated during transient events. The low on-state resistance also ensures that the device does not generate heat when exposed to high current or voltage transients.

The SP3130-01ETG TTVS diode is constructed with a positive temperature coefficient which allows the diode to adjust its internal resistance as temperature increases or decreases. This helps ensure that the diode does not become a thermal runaway. The diode also incorporates a number of protective features to ensure maximum reliability including ESD protection, high-energy protection, and steady-state protection.

In summary, the SP3130-01ETG TTVS diode is ideal for a range of applications including automotive electronics, consumer electronics, automotive sensors, and telecommunications. The diode features a breakdown voltage of 30V, reverse breakdown voltage of 12V, and an operating temperature range of -55°C to +155°C. The device also features an ultra-low dynamic impedance, steady-state protection, and other protective features. This makes it an ideal choice for applications that need reliable surge protection.
