DESCRIPTION
Microsemi’s proprietary Zener process provides low standoff voltages and the lowest standby current in the industry of 0.1µA. This 3 pin unidirectional array is designed for use in applications where protection is required at the board level from voltage transients caused by electrostatic discharge (ESD) as defined by IEC 61000-4-2, electrical fast transients (EFT) per IEC 61000 -4-4 and effects of secondary lighting. This product is designed to provide protection in the unid irectional mode for 1 line as defined in (Fig 1). Two device in an anti parallel configuration will provide low capacitance bidirectional protection as defined (Fig 2), and low capacitance bidirectional one line differential line pair protection as defined in (Fig 3 ). These Transient Voltage Suppressor (TVS) diode arrays protect 2.8 volt components such as DRAM’s SRAM’s CMOS, HCMOS, HSIC, and low voltage interfaces. Because of the physical size, weight and protection capabilities, this product is ideal for use in b ut not limited to miniaturize electronic equipment such as hand held instruments, computers, computer peripherals and cell phones and PDA’s.
