| Philips Semiconductors Product specification Rectifier diodes ultrafast GENERAL DESCRIPTION Glass passivated high efficiency rectifier diodes in a plastic envelope, featuring low forward voltage drop, ultra-fast recovery times and soft recovery characteristic. They are intended for use in switched mode power supplies and high frequency circuits in general where low conduction and switching losses are essential.

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. 1994 All rights are reserved.
