C a u t i o n D u r i n g A P D O p e r a t i o n

If an APD is operated above its breakdown voltage without some form of current protection, it can draw enough current to permanently damage the device. To guard against this, the user can add either a pro-tective resistor to the bias circuit or a current-limit-ing circuit in the supporting electronics.

The breakdown voltage of an APD is dependent upon its temperature: the breakdown voltage de-creases when the APD is cooled. Consequently, a re-verse bias operating point that is safe at room tem-perature may put the APD into breakdown at low temperature. The approximate temperature depen-dence of the breakdown voltage is published in the spec sheet for the part, but caution should be exer-cised when an APD is cooled.

Low-noise readout circuits usually have high im-pedance, and an unusually strong current pulse from the APD could generate a momentary excessive volt-

age that is higher than the readout’s supply voltage, possibly damaging the input to the amplifier. To pre-vent this, a protective circuit should be connected to divert excessive voltage at the inputs to a power supply voltage line.

As noted in the specification, another consider-ation is that the APD gain changes depending on temperature. When an APD is used over a wide tem-perature range, it is necessary to use some kind of temperature compensation to obtain operation at a stable gain. This can be implemented as either regulation of the applied reverse bias according to temperature, feedback temperature control using a thermoelectric cooler (TEC) or other refrigerator, or both.

Upon request, Voxtel will gladly assist customers in implementing the proper controls to ensure safe and reliable operation of APDs in their system.
