FEATURES • • • • • WATER CLEAR PLASTIC WIDE SPECTRAL RESPONSE 0.1” (2.54mm) LEAD SPACING LOW DARK CURRENT HIGH SENSITIVITY 0.015 0.018 DESCRIPTION 0.095 0.105 The SMP550G-X1 is a silicon PIN photodiode which is incorporated in a colourless plastic package. The terminals are solder tabs with 0.1” (2.54mm) spacing. Due to its design the diode can be assembled vertically on PC board. Active Area 0.125 0.165 0.080 0.105 0.015 0.018 Arrays can be realised by multiple arrangements. This versatile photo detector can be used as a diode as well as a voltage cell. TO-92 Package The signal / noise ratio is particularly favourable , even at low illuminances. The PIN photodiode is outstanding for low junction capacitance , high cut off frequency and short switching time. It is particularly suitable for IR sound transmission and remote control.
