NOTES

REV 1
1)
Stresses beyond those listed under absolute maximum ratings may cause permanent damage
to the device. Exposure to any absolute maximum rating condition for extended periods may affect
device reliability and longevity.
2)
Larger negative voltages will blow internal fuse. If fuse blows, as long as VA is not more negative
than -21/-39 V for model ORxxxA/ORxxxB, respectively, and is less than VK, no damage to device will
occur. Call manufacturer to replace blown fuse.
3)
Transient-protected to 40 V. Additional external protection may be required in some applications.
4)
Transient-protected to 60 V. Additional external protection may be required in some applications.
5)
Using the rectifier with the device ground disconnected is not recommended. Exceeding any of
these ratings will cause excessive heat buildup, leading to MOSFET failure.
6)
Transient-protected to -60 V. Additional external protection may be required in some applications.
7)
IS sourced from cathode (anode), when VA < VK (VA > VK).

SAMPLE APPLICATIONS
Diagram 1
POWER-GATE OR’ing diode (non-programmable) is designed to selectively OR one of two sources to a
load. The device will automatically conduct current from the source with higher voltage (relative to
device ground) to the load. When the primary source drops below the secondary source, the device will
“flip,” and current from the secondary will drive the load. The orientation of the internal MOSFET arrays
insures there will be no disruption in power driving the load, even when transitioning from one source
to another (refer to figure 2).
If source voltage levels are sufficiently close enough, dynamic voltage sag/rise of one source in
response to the opposing source sag/rise can cause oscillation or rapid-switching between the sources.
In this case, the “Programmable” OR’ing should be considered. Contact engineering for assistance.
