| SMP690G-JQS MECHANICAL DATA Dimensions in mm. P.I.N. PHOTODIODE FEATURES * * * * * * * * HIGH SENSITIVITY EXCELLENT LINEARITY LOW NOISE WIDEST SPECTRAL RESPONSE ENHANCED UV SENSITIVITY INTEGRAL OPTICAL FILTER OPTION note 1 TO8 HERMETIC METAL CAN PACKAGE EMI SCREENING MESH AVAILABLE O 14.0 O 12.0 O 0.45 LEAD 38 nom. 5.5 Note 1 Contact Semelab Plc for filter options 8.0 DESCRIPTION The SMP690G-JQS is a Silicon P.I.N. photodiode incorporated in a hermetic metal can package. The package window has greater ultra-violet light transmission, thus extending the useful spectral range of the device. The electrical terminations are via two leads of diameter 0.018" on pitch of 0.2". The cathode of the photodiode is electrically connected to the package. The larger photodiode active area provides greater sensitivity than the SMP600 range of devices, with a corresponding reduction in speed. The photodiode structure has been optimised for high sensitivity, light measurement applications across the infra-red to ultraviolet spectrum. Inclusion of a suitable optical filter into the package can produce a device that responds only to ultraviolet light. The metal can and optional screening mesh ensure a rugged device with a high degree of immunity to radiated electrical interference. 2 1 TO8 Small Pin 1 - Anode Pin 2 - Cathode & Case ABSOLUTE MAXIMUM RATINGS (Tcase = 25C unless otherwise stated) Operating temperature range Storage temperature range Temperature coefficient of responsively Temperature coefficient of dark current Reverse breakdown voltage Semelab plc.
