SR70 Series - 70V 40A Diode Array

DataSheet:TVS Diode Array SR70 Datasheet

SR70 Series TVS Diode Arrays (SPA^®Devices) provide protection against lightning-induced surges and ESD for telecom interfaces like VDSL and VDSL2

SR70 Series TVS Diode Arrays (SPA^®Devices) are ideal for protecting telecommunication interfaces such as VDSL and VDSL2 from damage due to lighting-induced surges and electrostatic dissipation (ESD). The device consists of four low capacitance, rail-to-rail diodes to provide robust protection by steering damaging transients into the power rails away from the IC. SR70 Series TVS Diode Arrays can safely absorb up to 40A (t_P=8/20μs) and repetitive ESD strikes at ±30kV without performance degradation. When compared with competitive devices, the SR70 Series offers far greater protection against surge-related damage, including a much higher surge rating (40A vs. just 24A or 27A from competitive devices), a much lower loading capacitance level (2.0pF typical vs. anywhere from 2.5pF to 10pF), and a much higher ESD rating (30kV vs. 8kV).

Features:

Robust surge protection allows up to 40A (t_P=8/20μs, IEC61000-4-5) without performance degradation and helps ensure compliance with regulatory standards.
Low loading capacitance (2pF typical) from each I/O to ground minimizes signal degradation and makes them an ideal choice for protecting high-speed data lines such as VDSL and VDSL2.
Enhanced ESD protection (±30kV contact, ±30kV air) exceeds the highest level of the IEC61000-4-2 standard (±8kV).
Compact SOT143 package conserves board space, allowing designers greater flexibility when placing circuit protection devices.
Extremely low dynamic resistance (0.35Ω) ensures excellent clamping performance to protect sensitive ICs.
