Product Description
Littelfuse SD12C-01FTG is a 1-element bi-directional Transient Voltage Suppressor (TVS) diode array designed to protect sensitive electronics from destructive electrostatic discharges (ESD) and high-energy surge currents. This device features a compact 2-pin SOD-323 surface mount package delivering robust 450W peak pulse power dissipation and can handle surge currents up to 17A.
This TVS Diode Array offers low dynamic resistance that significantly reduces clamping voltage, enhancing protection effectiveness compared to traditional multilayer varistors. It sustains repetitive ESD strikes rated at ±30kV without degradation, making it ideal for enduring harsh industrial and automotive electrical environments.
The device's operating temperature range from -40°C to 125°C makes it suitable for a variety of applications including automotive electronics, test and measurement equipment, point-of-sales terminals, notebook computers, servers, and medical devices requiring reliable surge protection.
The compact SOD-323 package design fits within existing 0805 PCB footprints, allowing easy integration without redesigning printed circuit boards. Its 2-pin configuration and surface mount form factor enable efficient, high-density circuit assembly.
Key features include:. Single diode configuration with bi-directional operation for line-to-line protection. Peak pulse power dissipation of 450W and clamping voltage of 23V ensures robust transient suppression. Compliance to automotive AEC-Q101 standard for automotive-grade quality assurance.
Low maximum reverse leakage current of 1μA reduces standby power consumption. Operating and storage temperature range between -40°C and 125°C.
This Littelfuse SD-C Series diode array is highly effective for fast acting transient voltage suppression, ideally replacing multilayer varistors (MLVs) in low-speed and DC circuits to improve reliability and longevity of electronic equipment.
EnvMart customers seeking reliable surge protection solutions for industrial, automotive, medical, laboratory, and commercial electronics will find this product aligns well with stringent performance and durability requirements.
