HARACTERISTICS
The XPD0250CT-001 can handle input optical power from 6µW to 1.7mW which is equivalent to a
dynamic range of 49dB. At low input optical power, the transimpedance gain ZT must be high to
obtain enough output voltage, and the noise should be low enough to guarantee a minimum bit error
rate. The transimpedance is regulated from 4
㏀
at low input optical power (Po<30µW) to 80Ωat
high power (Po =1.7mW).

RECAUTIONS FOR
U
SE
ESD protection is imperative. Use of ground straps, anti static mats, and other standard ESD
protective equipment is recommended when handling or testing an InGaAs PIN/APD or any other
junction photodiode.
Soldering temperature of the leads should not exceed 260℃ for more than 10 seconds.
Fiber pigtails should be handled with less than 10 N pull and with a bending radius greater than 1
inch.
