Low Capacitance TVS Diode Arrays from Littelfuse Combine High Signal Integrity at High Operating Voltages with Low Leakage
2016-07-21 | ReturnApplications for the SP3118 and SP3130 Series include tablets, ultrabooks, e-readers, smartphones, digital cameras, MP3/PMP players, set-top boxes, portable medical devices, and electronics enabled by Near Field Communication (NFC) and Felicity Card (FeliCa) protocols.
“The nominal voltages for the data antenna lines that the SP3118 and SP3130 Series are designed to protect are less than 3V. During antenna mismatch events, the interfaces of these products may experience up to five times the nominal voltage encountered during an NFC handshake,” said Tim Micun, product manager/TVS Diode Arrays. “These new TVS Diode Arrays permit the elevated signal voltages to pass and distinguish them from ESD events.”
SP3118 and SP3130 Series TVS Diode Array offer these key benefits:
。Their low capacitance (0.3pF @ VR=0V) minimizes signal degradation or attenuation for high-speed data, giving engineers more signal margin in their designs.
。Ultra-low leakage at max reverse standoff voltage (VRWM) helps to preserve battery life and signal integrity. Excessive leakage can be seen as additive capacitance for a high-speed differential pair.
。 Enhanced ESD capability (±10kV contact, ±15kV air) permits manufacturers to achieve ESD protection beyond the maximum level stated in the IEC standard and protects against a multitude of other threats to ensure product reliability in the field.
。 Small form factors (SOD882 for SP3118-01ETG and SP3130-01ETG; 0201 flip chip for SP3118-01WTG and SP3130-01WTG) save precious board space, simplify the PCB layout, and allow for protection in space-constrained applications like smartphones.
Availability
The SP3118 and SP3130 Series are provided in tape & reel packaging in quantities of 10,000. Sample requests can be placed through authorized Littelfuse distributors worldwide. For a listing of Littelfuse distributors, please visit Littelfuse.com.
