Product Description
Littelfuse SP4020-01FTG is a 3-element uni-directional TVS diode array designed for high-performance surge protection in sensitive electronic circuits. This device offers a peak pulse power dissipation rating of 750 W, enabling it to withstand substantial transient energy typically encountered during lightning strikes or electrical faults. Housed in a compact 2-pin SOD-323 surface mount package, it provides a space-saving solution for PCB designs requiring robust protection with minimal footprint.
Featuring low typical capacitance of 2.5pF, the diode array minimizes signal distortion, making it ideal for safeguarding high-speed data and telecommunication lines without compromising signal integrity. Its enhanced electrostatic discharge (ESD) protection capability ensures resilience during handling, installation, and equipment operation.
The diode operates reliably across a broad temperature range from -40°C to 125°C, with a maximum peak pulse current of 30A and a clamping voltage of 21.8V, thereby offering excellent protection to delicate components. The device exhibits a low dynamic resistance of 0.7Ω, further contributing to system reliability by reducing voltage drop during surge events.
This Littelfuse TVS diode array conforms to the automotive standard AEC-Q101, affirming its suitability for automotive and industrial applications where rigorous quality and reliability are essential. The product’s small size (1.9mm length, 1.45mm width, and 1.04mm height) facilitates integration into compact designs across a variety of industrial sectors.
Common applications include protection of 10/100/1000 Ethernet lines, T1/E1/T3/E3 data communications, USB 1.1/2.0 interfaces, power ports, computers, peripherals, instrumentation, and medical equipment. The diode array plays a critical role in maintaining system integrity and durability against electrical surges and ESD events.
