PRODUCT PREVIEW
DESCRIPTION
TVS array™ SERIES
This diode Series array is packaged in a SOIC-08 configuration giving protection
to 1 line bi-directional or 1 line pair differential mode. It is designed for use in
applications were protection is required at the board level from voltage transients
caused electrostatic discharge (ESD) as defined in IEC 61000-4-2, electrical
transients (EFT) per IEC 61000-4-4 and effects of secondary lighting.
The MLC496 TVS array has a peak power rating of 500 watts for an 8/20 µsec
pulse. This array is suitable for protecting sensitive circuitry consisting of TTL,
DRAM’s SRAM’s CMOS, HCMOS, HSIC, microprocessors, and low voltage
interfaces. It provides protection for UNIVERSAL SERIAL BUS (USB) and I/O
transceivers. Because of its LOW STANDBY CURRENT it provides superb
component protection for battery-operated equipments. Because of the physical
size, weight and protection capabilities, this product is ideal for use in but not limited
to miniaturized electronic equipment such as hand held instruments, computers,
computer peripherals and cell phones.
