Description
The OLH249 is designed especially for high-reliability applications
that require optical isolation in radiation environments, such as
gamma, neutron, and proton radiation with high CTR and low
saturation VCE. Each optocoupler consists of an LED and N-P-N
silicon phototransistor electrically isolated, but optically coupled
inside a hermetic TO-5 package. Electrical parameters are similar
to the JEDEC registered 4N49 optocoupler, but have much better
CTR degradation characteristics due to radiation exposure
(contact IsoLink for more information). The OLH249 has 100
percent high-reliability screened parts available.

Figure 1 shows the OLH249 functional block diagram. Table 1
provides the OLH249 absolute maximum ratings. Table 2 provides
the OLH249 electrical specifications.
Figures 2 through 4 illustrate the OLH249 typical performance
characteristics. Figure 5 shows the OLH249 switching test circuit.

Measured between pins 5, 6, and 7 shorted together, and pins 1, 2, and 3 shorted together. TA = 25 °C and duration = 1 second.
Value applies for Pw ≤1 ms, PRR ≤300 pps.
Derate linearly at 3.0 mW/°C above 25 °C.
ESD HANDLING:Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device.
This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce
potentials of several kilovolts on the human body or equipment, which can discharge without detection.
Industry-standard ESD handling precautions should be used at all times.

Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to the device with only one parameter set at the limit and all other parameters set at
or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
