DESCRIPTION

These low capacitance diode arrays are multiple, discrete, isolated junctions fabricated by a planar process and mounted in a 14-PIN ceramic DIP package for use as steering diodes protecting up to eight I/O ports from ESD, EFT, or surge by directing them to the positive side of the power supply line and to ground (see Figure 1). An external TVS diode may be added between the positive supply line and ground to prevent overvoltage on the supply rail. They may also be used in fast switching core-driver applications.

FEATURES

• Hermetic Ceramic Package

• Isolated Diodes to Eliminate Cross-Talk Voltages

• High Breakdown Voltage VBR > 60 V at 10 μA

• Low Leakage IR< 100nA at 40 V

• Low Capacitance C < 8.0 pF

• Switching Speeds less than 20 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 MSP prefixes respectively to part numbers. For example, designate MX1N6508 for a JANTX screen.
