PHOTODIODE Si PIN photodiode with preamp S6468 series High-speed sensor with preamp S6468 series is a high-speed photodetector consisting of a Si PIN photodiode and a preamplifier chip integrated in the same package. They feature high-speed response and high sensitivity over a wide spectral range from visible to near infrared light. The small package (TO-18) allows compact optical design. The amplifier input is at a virtual ground, so external noise which may appear when detecting high-speed signals can be suppressed.

The following precautions must be observed during use: * To protect the device from electro static discharge which accumulate on the operator or the operator's clothes, use a wrist strap or similar tools to ground the operator's body via a high impedance resistor (1 M). * A semiconductive sheet (1 M to 100 M) should be laid on both the work table and the floor in the work area. * When soldering, use an electrically grounded soldering iron with an isolation resistance of more than 10 M. * For containers and packing, use of a conductive material or aluminum foil is effective. When using an antistatic material, use one with a resistance of 0.1 M/cm 2 to 1 G/cm2. Wiring * RL and CL are total resistive load and capacitive load viewed from the V signal terminal. When connecting a cable or circuit to the latter stage of the basic connection diagram, the cable or circuit resistance and capacitance should also be taken into account. They should be used in accordance with the recommended operating conditions: RL500 and CL 13 pF. * A bypass capacitor (CB=0.01 F to 0.1 F ceramic) is connected between the Vcc lead and the GND lead. * The lead length should be less than 20 mm. * If electric current or voltage is applied in reverse polarity to an electronic device such as a preamplifier, this can degrade device performance or destroy the device. Always check the wiring and dimensional outline to avoid misconnection. Information furnished by HAMAMATSU is believed to be reliable.
