1.0 DESCRIPTION
1.2 SPACE LEVEL CHARACTERIZATIONS
The SVCL Series of space qualified Inrush Current Limiters are
specifically designed for the harsh radiation environment of
space applications. Performance is guaranteed through the use
of hardened semiconductor components, radiation lot
• Guaranteed TID performance to 100 krad(Si) including ELDRS
• SEE performance to 85 MeV/mg/cm2. Transients are fully
characterized for cross section and magnitude
• Worst-case analysis, stress, radiation, reliability reports available
acceptance testing (RLAT) of non-hardened components, and
analysis. The SVCL Series has been characterized for Total
Ionizing Dose (TID) performance including Enhanced Low Dose
Rate Sensitivity (ELDRS) and for Single Event Effects (SEE)
according to VPT’s DLA-approved Radiation Hardness
Assurance (RHA) plan per MIL-PRF-38534, Appendix G,
Level R. Characterization is performed at both the component
level and at the SVCL Series hybrid converter level. The SVCL28
is designed to control the inrush current drawn by VPT’s EMI
filters and DC-DC converters during turn-on. The SVCL28
functions by limiting the rate of rise of its output voltage and will
also control the inrush current of discrete input capacitors.
