Note:

(1) Test surface is a front surface mirror (polished aluminum, 85% reflectance) located 0.50 in.(12.7 mm) from the front surface of the device.

(2) Tested with a pulsed LED at 1 KHz

(3) Tested with a pulsed LED at 100 Hz

(4) To calculate typical collector dark current in nA , use the formula ICEO = 10

(0.040TA-3.4) where T

A is ambient temperature in °C
