September 1998 4 Rev 1.300 Philips Semiconductors Product specification Rectifier diodes general purpose DEFINITIONS Data sheet status Objective specification Product specification Limiting values BY249 series This data sheet contains target or goal specifications for product development. This data sheet contains final product specifications. Preliminary specification This data sheet contains preliminary data; supplementary data may be published later. Limiting values are given 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 this specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Where application information is given, it is advisory and does not form part of the specification. (c) Philips Electronics N.V. 1998 All rights are reserved.
