Product Description
Littelfuse SP4020-01FTG is a 3-element uni-directional TVS diode array designed for surge protection in telecommunications and high-speed data communication applications. This device offers a peak pulse power dissipation of 750 watts and is housed in a compact 2-pin SOD-323 surface mount package, suitable for space-constrained PCB layouts.
Its low capacitance of 2.5 pF typical ensures minimal impact on signal integrity, making it ideal for protecting Ethernet, USB 1.1 and 2.0, and other sensitive data lines without degrading the data quality. The diode array provides robust ESD protection and low dynamic resistance (0.7 Ω), which results in low clamping voltages, safeguarding delicate chipsets from transient voltage spikes.
Operating over a broad temperature range from -40°C to 125°C and complying with the automotive AEC-Q101 standard, the SP4020-01FTG ensures reliability in demanding environments including automotive, industrial, and professional electronics.
Physical dimensions are compact, at 1.9 mm length, 1.45 mm width, and 1.04 mm height, making it an excellent choice for integration into high-density circuit designs. Peak pulse power dissipation of 750 W enables protection against lightning-induced surges.
Uni-directional diode configuration supports effective voltage clamping. Low input capacitance of 2.5 pF preserves signal integrity on high-speed data lines. Surface mount SOD-323 package facilitates automated assembly on PCBs.
Enhanced ESD protection ensures device longevity during handling and operation. Passes automotive standard AEC-Q101 durability and quality testing. Low dynamic resistance reduces clamping voltage and power dissipation. Suitable for applications including Ethernet (10/100/1000 Mbps), T1/E1/T3/E3 data lines, USB ports, instrumentation, computers, and medical equipment.
This Littelfuse TVS diode array is a premium component for protecting sensitive electronic devices from surge and transient voltages in industrial, laboratory, communication, and automotive sectors. It combines high power capability with low capacitance, making it an industry-leading solution for signal line protection.
