HSDL-5420

The HSDL-5420 is designed as one member of the HDSL-54xx IR detector series which have high performance IR emitter and IR pin photodiode in subminiature SMT package. Typical applications is short distance IR links, IrDA compatible, small handheld devices pagers industrial handhelds, diffuse LANs and wireless audio.

HSDL-5420 has five features. (1)Subminiature flat top and dome package size-2x2mm. (2)IR emitter 875nm TS AlGaAs intensity-17mW/sr speed -40ns. (3)Wide range of drive currents 500mA to 500mA. (4)IR detector PIN photodiode high sensitivity speed-7.5ns. (5)Flexible lead configurations surface mount or through hole. Those are all the main features.

Some absolute maximum ratings of HSDL-5420 have been concluded into several points as follow. (1)Its power dissipation would be max 150mW. (2)Its reverse voltage would be max 40V at Ir=100uA. (3)Its operating temperature range would be from -40°C to 85°C. (4)Its storage temperature range would be from -55°C to 100°C. (5)Its junction temperature would be max 110°C. (6)Its lead solder temperature 1.6mm (0.063 inch) from body would be max 260°C/5s. (7)Its reflow soldering temperature would be 235°C/90s for convection and would be 215°C/180s for vapor phase. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of HSDL-5420 are concluded as follow. (1)Its forward voltage would be typ 1.8V. (2)Its breakdown voltage would be min 40V. (3)Its reverse dark current would be typ 1mA and max 5mA. (4)Its series resistance would be typ 2000ohms. (5)Its diode capacitance would be typ 5pF. (6)Its open circuit voltage would be typ 375mV. (7)Its temperature coefficient of Voc would be typ -2.2mV/K. (8)Its short circuit curent would be typ 4.3uA. (9)Its temperature coefficient of Isc would be typ 0.16%/K. (10)Its thermal resistance junction to pin would be typ 170°C/W. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
