PSRDA3.3-6 - PSRDA05-6
500 WATT ULTRA LOW CAPACITANCE STEERING DIODE/TVS ARRAY
DESCRIPTION
The PSRDAxx-6 Series are low capacitance multi-line steering diode/transient voltage suppressor arrays that provides
board level protection for standard TTL and CMOS bus line applications against the damaging effects of ESD, tertiary
lightning and switching transients.
The PSRDAxx-6 Series has a peak pulse power rating of 500 Watts for an 8/20µs waveshape. This device series meets
the IEC 61000-4-2, IEC 61000-4-4 and IEC 61000-4-5 requirements.
