TVS diodes from Littelfuse with improved surge protection and power handling

Littelfuse has introduced the SRDA3.3 Series TVS Diode Array – SPA Diodes integrated with low-capacitance steering diodes with an additional zener diode to protect data lines against electrostatic discharge (ESD) and high surge events. Littlefuse claims SRDA3.3 series provides greater protection, better power handling capability and low loading capacitance compared to other solutions in the market.

Applications include tertiary (IC side) protection of high-speed T1/E1/T3/E3 telecommunications data lines, xDSL interfaces, RS-232/RS-485 interfaces, 10/100 Ethernet interfaces and video lines.

“The SRDA3.3 Series superior surge, power dissipation, and ESD performance, gives circuit design engineers a simple way to provide greater overhead against electrical threats as defined by industry standards,” said Chad Marak, Director of the TVS Diode Arrays product line. “The low dynamic resistance of these devices ensures very low clamping voltages, which helps protect today’s increasingly sensitive chipsets from premature failure.”

Key specifications:
Surge protection: Lightning, IEC61000-4-5, 35A (8/20µs), peak pulse power, 600W (8/20µs)
Dynamic resistance (RDYN) of 0.5 ohms
Dow capacitance of 8pF (typ) /10pF (max) from I/O to GND
ESD capability: ESD, IEC61000-4-2, ±30kV contact, ±30kV air

The SRDA3.3 Series TVS Diode Arrays are available in quantities of 2,500 in tape and reel packaging. Samples are available now.
