Series LD00KQ 20A, 270Vdc, Optically Isolated NEW Silicon Carbide DC Solid-State Relay Part* Relay Number Description LD00KQ 270Vdc, 20A Solid State Relay * The Y suf x denotes parameters tested to MIL-PRF-28750 speci cations. The W suf x denotes parameters tested to Teledyne Speci cations. ELECTRICAL SPECIFICATIONS (55C to +125C UNLESS OTHERWISE NOTED) FEATURES High Voltage INPUT (CONTROL) SPECIFICATIONS Low ON resistance power SiC MOSFET output Min Typ Max Units Fast switching speed Meets 270 Vdc system requirements of Input Current V = 5 Vdc(See Fig 2,4) 50 mA IN MIL-STD-704 Turn-Off Voltage (Guaranteed Off) 1.5 Vdc Optical isolation Turn-On Voltage (Guaranteed On) 4.2 Vdc Low pro le hermetic package Reverse Voltage Protection* -32 Vdc Built and tested to the requirements of Input Supply Range (See Note 1) 4.2 18 Vdc MIL-PRF-28750 *Guaranteed by design but not tested DESCRIPTION The Series LD00KQ solid-state relays are screened utilizing MIL-PRF-28750 test methods and are packaged in low pro le hermetically sealed cases. These relays are constructed with state-of-the-art solid state techniques and feature fully oating power FET output technology. This allows the load to be con- nected to either output terminal and provides a low ON resistance. The input and output are optically isolated to protect input logic circuits from output transients.
