Technical content

  • Twice the power output of GaAs at the same drive current
  • Characterized to define infrared energy along the mechanical axis of the device
  • Mechanically and spectrally matched to the OP804TX/TXV and OP805TX/TXV phototransistors
  • Screened per MIL-PRF-19500 TX or TXV equivalent levels De scrip tion The OP235TX, TXV and OP236TX, TXV are high reliability gallium aluminum arsenide infrared emitting diodes mounted in hermetic TO-46 packages. The wavelength is centered at 890 nanometers to closely match the spectral response of silicon photoransistors. Devices are processed to Optek’s 100% screening and quality conformance program patterned after MIL-PRF-19500. After 100% screening, Group A and B are performed on every lot, and a Group C test is performed every six months. The OP235TX, TXV and OP236TX, TXV have lens cans providing a narrow beam angle (18o between half power points). The narrow beam angle and the specified radiant intensity allow ease of design in beam interrupt applications with the OP804TX, TXV and OP805TX, TXV series of high reliability phototransistors. Ab so lute Maxi mum Rat ings (TA = 25o C un less oth er wise noted) Lead Sol der ing Tem pera ture [1/16 inch (1.6mm) from case for 5 sec. with sol der ing Notes: (1) RMA flux is recommended. Duration can be extended to 10 seconds max. when flow soldering. (2) Derate linearly 2.00 mW/o C above 25o C. (3) Ee(APT) is a measurement of the average radiant intensity within the cone formed by the measurement surface. The cone is outlined by a radius of 1.429 inches (36.30 mm) measured from the lens side of the tab to the sensing surface and a sensing surface of 0.250 inches (6.35 mm) in diameter forming a 10o cone. Ee(APT) is not necessarily uniform within the measured area. Typical screening and lot acceptance tests are provided on page 13-4.
