2.6.1
Summary Description
The NEXSYS Diode Pack (DP2C, DP2M) is a Series A (4 Pin) component designed to replace external in-line harness diodes and enhance avionics design flexibility. Each Diode Pack component contains two independent diode circuits, see Figure 2.6.1.0-A.
The NEXSYS Diode Pack (DP2C, DP2M) is commercial-off-the-shelf (COTS) item. This standard catalog hardware includes features to allow for flexible interface design solutions while also meeting aircraft performance standards. The DP is designed, tested, and qualified to MIL-PRF-22885/116, MIL-PRF-22885/117, DO-160 and MIL-STD-461 requirements. Specifications are available in our MIL-PRF and DO-160 Documents page, and the qualification table is available in Appendix A.
Input/Output (I/O) Characteristics
NEXSYS Diode Packs are manufactured with the polarity arranged from Anode (PIN 1, 4) to Cathode (PIN 2, 3), see Figure 2.6.1.1-A.
Configuration Options
The NEXSYS Diode Pack is available in two different configurations, commercial and military.
Commercial Diodes (DP2C)
Two 1N6484 glass passivized diodes (Vishay® or equivalent). Consult manufacturer’s datasheet for detailed diode specifications. 1.0 A average forward current
Military Diodes (DP2M)
Two JANTX1N5621 Hermetic glass sealed diodes (Microsemi or equivalent). Consult manufacturer’s datasheet for detailed diode specifications. The integrated JEDEC Registered diodes feature triple-layer passivation and inherently radiation hard.
