Dynamic Characteristics
-40 °C to +85 °C; 4.75 V d Supply Voltage d 5.25 V; R
Notes:
1. 2.0 mm from where leads enter case.
2. Typical specifications are for operation at T
3. For 200 μm HCS fibers, typical responsivity will be 6 mV/mW. Other parameters will change as well.
4. Pin #2 should be ac coupled to a load ³ 510 ohm. Load capacitance must be less than 5 pF.
5. Measured with a 3 pole Bessel filter with a 75 MHz, -3 dB bandwidth. Recommended receiver filters for various bandwidths are provided in
6. Overdrive is defined at PWD = 2.5 ns.
7. D is the effective diameter of the detector image on the plane of the fiber face. The numerical value is the product of the actual detector di-
8. Measured with a 10 ns pulse width, 50% duty cycle, at the 50% amplitude point of the waveform.
9. Percent overshoot is defined as:
10. The conversion factor for the rise time to bandwidth is 0.41 since the HFBR-24x6Z has a second order bandwidth limiting characteristic.

CAUTION: The small junction sizes inherent to the design of these components increase the components’ susceptibility to damage
from electrostatic discharge (ESD). It is advised that normal static precautions be taken in handling and assembly of these compo-
nents to prevent damage and/or degradation which may be induced by ESD.
