PSRDA3.3-4 - PSRDA15-4

500 WATT LOW CAPACITANCE STEERING DIODE/TVS ARRAY

DESCRIPTION

The PSRDAxx-4 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-4 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.
