Product specification
High-voltage soft-recovery controlled avalanche rectifier
FEATURES * Glass passivated * High maximum operating temperature * Low leakage current * Excellent stability * Soft-recovery switching characteristics * Guaranteed avalanche energy absorption capability. APPLICATIONS * High-voltage rectification at high frequencies * Sub-component for very high voltage rectifiers, for example, in X-ray and radar equipment. DESCRIPTION Rugged glass package, using a high temperature alloyed construction. This package is hermetically sealed and fatigue free as coefficients of expansion of all used parts are matched.
BYX90G
The package is designed to be used in an insulating medium such as resin, oil or SF6 gas.

DEFINITIONS Data Sheet Status Objective specification Preliminary specification Product specification Limiting values 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 information is given, it is advisory and does not form part of the specification. LIFE SUPPORT APPLICATIONS These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips for any damages resulting from such improper use or sale. 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.
