The absolute maximum ratings are limiting values, to be applied individually, beyond which the device may be permanently damaged. Functional

operation under any of these conditions is not guaranteed. Exposing the device to its absolute maximum rating may

affect its reliability.

STANDARD PART ORDERING INFORMATION

Note 1:

The test circuit depicts the Schottky diodes in their typical application. The impact of a reverse recovery time is measured

using a narrow pulse with 670- pS rise and fall times. This pulse propagates down a 60 cm, 54 ohm strip line fabricated on

a multi-layer, controlled impedance printed circuit board. In testing the ground clamp diode, the negative going edge of the

pulse causes a reflection which forces the diode under test to become forward biased. The positive going edge of the pulse

attempts to pull this diode out of forward conduction. A reverse recovery phenomenon would cause a delay between the

known arrival time of the positive edge and the observed edge due to the time it takes for the forward biased diode to actually

become reversed biased. In this measurement, however, there is no observable difference and therefore no delay for the

positive edge due to the presence of the diode. The waveforms are adjusted to individually test the ground and VDD clamps.

See test circuit.

Test Circuit. Line length, pulse width and duty cycle are selected such as that only one reflection is involved

in the measurement.
