Technical Documents

Electronic parts called TVS (Transient Voltage Suppression) diodes from Littelfuse Inc.'s SP1002 and SPA® series are made to shield delicate electronics from voltage surges and transients.

For the purpose of shielding delicate electronic equipment from electrostatic discharge (ESD) and other voltage transients, the SP1002 series is a low-capacitance TVS diode. It is perfect for use in applications that call for quick response times and low power consumption since it has low clamping voltage and low leakage current.

On the other hand, the SPA® series TVS diodes are made to safeguard delicate electronics from voltage spikes brought on by lightning strikes, electrostatic discharge, and other transient occurrences. As a result of their high surge current capabilities, low clamping voltage, and low leakage current, they can be used in a variety of industrial, telecommunications, and automotive electronics applications.

The SPA® series TVS diodes and the SP1002 TVS diodes both provide outstanding protection against voltage surges and transients, extending the life and dependability of electronic equipment.

Frequently Asked Questions

What is TVS diode?

A transient voltage suppression diode, often known as a TVS diode, is an electrical component used to shield delicate electronics from voltage surges and transients. It functions by rerouting excessive voltage away from the protected circuit, shielding it from harm along with other components.

What distinguishes the SPA® series TVS diodes from the SP1002 TVS diodes?

The SP1002 series has low capacitance, low clamping voltage, and low leakage current and is intended for use in high-speed data lines. The SPA® series provides strong surge current capability, low clamping voltage, and low leakage current for protection against high-surge occurrences like lightning strikes.

What types of electronics can be protected using SP1002 and SPA® series TVS diodes?

Several different types of electronics, such as smartphones, tablets, audio and video equipment, medical equipment, industrial control systems, automotive electronics, telecommunications equipment, and more, can be protected by using these TVS diodes.
