1. Refer to SOT223 standard mounting conditions. 2. For Schottky barrier diodes thermal run-away has to be considered, as in some applications, the reverse power losses PR are a significant part of the total power losses. Nomograms for determination of the reverse power losses PR and IF(AV) rating will be available on request. ELECTRICAL CHARACTERISTICS Tamb = 25 °C unless otherwise specified.

DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values
BAT140 series
This data sheet contains target or goal specifications for product development. This data sheet contains preliminary data; supplementary data may be published later. This data sheet contains final product specifications.
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Where application inform.
