FEATURES • Stable operation over wide temperature range • Low leakage current • Low peak point current • Guaranteed minimum pulse voltage • Available as “HR” (high reliability) screened per MIL-PRF-19500, JANTX level. Add “HR” suffix to base part number. • Available Non-RoHS (standard) or RoHS compliant (add PBF suffix).
