Littelfuse Introduces Industry's Smallest Dimensional Unidirectional TVS Diode Array

The SP1053 and SP1054 series TVS Diode Arrays (SPA® diodes) integrate multiple avalanche breakdown diodes assembled with proprietary silicon avalanche technology to protect each pin. This type of device is a unidirectional fully-encapsulated transient suppression diode in a compact 01005 plastic package; these two features are the first in the transient suppression diode array market. This reliable diode safely absorbs repetitive ESD strikes at ±8kV (SP1053) or ±30kV (SP1054) without performance degradation. In addition, each diode can safely withstand 1.0A (SP1053) and 2.5A (SP1054) surges with extremely low clamping voltages.
 
Typical applications for the SP1053 and SP1054 series TVS diode arrays include mobile phones, smart phones, camcorders, portable medical devices, digital cameras, wearable technology, portable navigation devices, tablet computers, point-of-sale terminals, and identification modules.
"The unidirectional diodes of the SP1053 and SP1054 series should always be the preferred solution for protecting I/O and power ports from ESD damage because these lines are unidirectional." Littelfuse TVS Diode Array (SPA® Diode) Service Tim Micun, development manager, stated that “Unlike other devices of the same specification (bare silicon or bare silicon covered with oxide), the SP1053 and SP1054 series are housed in a hermetically-sealed plastic package that helps prevent wear, temperature cycling, and Wet."

The SP1053 and SP1054 series of TVS diode arrays provide the following key advantages:
• The first commercially available protective device that integrates the plastic package and the compact 01005 form factor prevents solder short-circuiting, abrasion, and moisture intrusion between terminals that can interfere with ESD protection.
• These unidirectional TVS diode arrays offer only half the dynamic resistance of a two-way solution, protecting sensitive ports faster and better.
• The ultra-small 01005 DFN hermetic package offers new options for circuit designers seeking to create a smaller, more compact final product.
