1.0 DESCRIPTION
1.2 SPACE LEVEL CHARACTERIZATIONS
The SVRSA Series of space qualified DC-DC converters is
specifically designed for the harsh radiation environment of
space applications and is designed in accordance with
Aerospace TOR requirements. Performance is guaranteed
through the use of hardened semiconductor components,
radiation lot acceptance testing (RLAT) of non-hardened
components, and analysis. The SVRSA 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 SVRSA Series hybrid converter level.
• 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
1.3 MANUFACTURING AND COMPLIANCE
• Qualified to MIL-PRF-38534 Class H and Class K,
DLA SMD 5962-15217
• Available compliant to MIL-HDBK-1547 and Aerospace TOR
component level element evaluation
• MIL-PRF-38534 element evaluated components
• MIL-STD-461 C/D/E/F when used with appropriate VPT EMI filter
