Gain, @ h=675nm Operating Temp Range (�C) Storage Temp Range (�C) TEC Voltage (V) @23�C (W) TEC Current (A) APD Die Power Dissipation (W)

Positive high voltage (HV) is applied to the cathode contact. The maximum value for the operating HV is specified with each device. * This is the temperature at the backside of the Cooled APD package. 9 Operating beyond these limits may cause permanent damage to the device.

571 has a thermistor with a resistance of 7650 ohms at 0�C and a negative temperature coefficient. 591 has a LM335 temperature sensing IC. Devices must be operated with a sufficient heat sink. Consult the factory for UV enhanced operation at wavelengths shorter than 350nm.
