Unidirectional TVS Diode Arrays Thwart ESD

Littelfuse’s two series of AEC-Q101-qualified, unidirectional TVS Diode arrays are optimized to protect I/O and power ports against electrostatic discharges (ESDs). SP1053 and SP1054 Series TVS Diode Arrays (SPA Diodes) integrate avalanche breakdown diodes fabricated using proprietary silicon avalanche technology to protect each pin. The devices are unidirectional and hermetically sealed in compact, 01005-format plastic packages. The diodes can safely absorb repetitive ESD strikes at ±8kV (for SP1053) or ±30kV (for SP1054) without performance degradation. Additionally, each diode can safely withstand 1A (for SP1053) and 2.5A (for SP1054) surges at a very low clamping voltage.


Typical applications include mobile phones, smartphones, camcorders, portable medical devices, digital cameras, wearable technology, portable navigation components, tablets, point-of-sale terminals and identification modules. Additional information is available on the SP1053 Series TVS Diode Array product page and SP1054 Series TVS Diode Array product page as well as datasheets for both series.
