Product Description
Littelfuse SP4021-01FTG is a high-efficiency 3-element Uni-Directional TVS Diode Array designed for surface mounting in a compact 2-pin SOD-323 package. It provides superior surge suppression with a peak pulse power of 600W, protecting sensitive electronic components from transient voltage spikes and electrostatic discharge.
This diode array features a minimum breakdown voltage of 6.3V and a maximum reverse stand-off voltage of 5V, allowing it to clamp transient voltages effectively at a low clamping voltage of 19.6V. With a low typical capacitance of 2.5pF, the device preserves signal integrity, making it highly suitable for high-speed data lines such as 10/100/1000 Ethernet, USB 1.1/2.0, T1/E1/T3/E3 data interfaces, and power ports.
The SP4021-01FTG device offers enhanced electrostatic discharge protection, meeting automotive AEC-Q101 standards for reliability in automotive and industrial environments. Its rugged design supports operation over a wide temperature range from -40°C to 125°C, ensuring dependable performance in harsh conditions.
Its low dynamic resistance of 0.52Ω reduces losses during surge events, and the compact dimensions (1.9mm length, 1.45mm width, and 1.04mm height) facilitate high-density PCB layouts. The diode array contains three elements per chip for robust multi-line protection.
This Littelfuse TVS Diode Array is ideal for safeguarding telecommunications equipment, computers, instrumentation, medical devices, and other sensitive electronics requiring effective transient voltage suppression.
