Electrical Parameters

Test conditions for the following specifications are Tamb = 25°C (typical) and VDD = 12V, unless otherwise noted.

Production testing of the ZLED7015 is performed at 25°C unless otherwise stated. Functional operation of the

ZLED7015 and specified parameters at other temperatures are guaranteed by design, characterization, and

process control.
