Littelfuse 4-Element Bi-Directional TVS Diode Array Surface Mount SOD-323 Package 750 W Peak Pulse Power SP4020-01FTG-C

Littelfuse SP4020-01FTG-C is a 4-element bi-directional TVS (Transient Voltage Suppressor) diode array engineered to provide reliable surge protection in a small, surface-mount SOD-323 package. With a peak pulse power dissipation rating of 750 W and the ability to handle pulse currents up to 30 A, this device safeguards sensitive electronics from damaging voltage transients caused by lightning and other electrical surges.

The device offers a low typical capacitance of 2.5 pF, making it particularly suitable for high-speed data interfaces, including 10/100/1000 Ethernet, T1/E1/T3/E3 data lines, USB 1.1 and 2.0, and power ports, where maintaining signal integrity is critical. Its low clamping voltage of 21.8 V ensures that connected components are protected from voltage spikes without compromising performance.

Designed for high reliability, the SP4020 series also features enhanced Electrostatic Discharge (ESD) protection and low dynamic resistance (0.7 Ω), contributing to superior device performance and longevity. The diode array operates effectively across a wide temperature range from -40°C to 125°C and meets automotive standard AEC-Q101, emphasizing suitability in demanding industrial and automotive environments.

The device’s compact dimensions (1.9 mm length, 1.45 mm width, and 1.04 mm height) allow for space-efficient PCB layouts. Its surface-mount package facilitates automated assembly processes and is compatible with modern manufacturing techniques.

Applications for the SP4020-01FTG-C include protection of telecommunications equipment, computer peripherals, instrumentation, medical devices, and other critical systems requiring surge and electrostatic transient voltage protection. The Littelfuse SP4020 series combines enhanced power handling with signal preservation features to ensure maximum system reliability and reduced downtime.
