DESCRIPTION

These low capacitance diode arrays are multiple, discrete, isolated junctions fabricated by a planar process and mounted in a 16-PIN ceramic flat pack for use as steering diodes protecting up to eight I/O ports from ESD, EFT, or surge by directing them either to the positive side of the power supply line or to ground (see figure 1). An external TVS diode may be added between the positive supply line and ground to prevent over-voltage on the supply rail. They may also be used in fast switching coredriver applications.

FEATURES

• Hermetic Ceramic Package

• Isolated Diodes to Eliminate Cross-Talk Voltages

• High Breakdown Voltage VBR > 75 V at 5 μA

• Low Leakage IR< 100nA at 40 V

• Low Capacitance Ct < 4.0 pF

• Switching Speeds less than 10 ns

• Options for screening in accordance with MIL-PRF-19500/474 for JAN, JANTX, JANTXV, and JANS are available by adding MQ, MX, MV, or SP prefixes respectively to part numbers. For example, designate MX6510A for a JANTX screen.
