CHICAGO, January 29, 2018 Littelfuse, Inc., the global leader in circuit protection, today introduced a series of AEC-Q101-qualified TVS Diode Arrays optimized to protect sensitive telecommunication ports against electrostatic discharge (ESD) and lightning-induced surge events. SP4208 Series TVS Diode Arrays (SPA® Diodes) integrate low capacitance steering diodes with either one avalanche breakdown diode (for unidirectional protection) or two (for bidirectional protection). They can safely absorb up to 30A of surge current and a minimum of ±30kV ESD without performance degradation. Their low loading capacitance (3.0pF) and high surge capability make them well-suited for protecting telecommunication ports such as Ethernet and other high-speed data interfaces.

Typical applications for SP4208 Series TVS Diode Arrays include:

  • 10/100/1000 Ethernet.
  • T1/E1/T3/E3.
  • USB 1.1/2.0, power ports.
  • Instrumentation.
  • 医療機器
  • Computers and peripherals.

"The SP4208 Series TVS Diode Arrays combine a standoff voltage of 8V with a low dynamic resistance, which supports those implementations of G.Fast that run at higher voltages," said Tim Micun Business Development Manager, TVS Diode Arrays (SPA® Diodes) at Littelfuse. "Their 'flow-through' design minimizes signal distortion, reduces voltage overshoot, and allows for a simpler printed circuit design."

SP4208 シリーズ TVS ダイオードアレイの主な特長:

  • The 8V nominal standoff voltage permits a higher operating voltage, which is an increasingly important consideration for high speed interfaces.
  • Low parasitic capacitance (nominally 3.0pF) allows for an appropriate amount of bandwidth to enable high speed Ethernet interfaces.
  • Extremely low dynamic resistance (nominally 0.4Ω) helps to ensure the fastest response during an ESD event.
