Microsemi Corp/Micro – S6E Series Silicon Epoxy Rectifiers Overview
The S6E series from Microsemi Corp/Micro is comprised of diffused silicon epoxy rectifiers with varied ratings tailored for different applications within the semiconductor industry. There are three principal categories within the series: Controlled Avalanche Types, Non-Controlled Avalanche Types, and Fast Recovery Types, each designed for specific performance needs.
Key Features
Controlled Avalanche Rectifiers are available with minimum avalanche ratings of 250V, 450V, 650V, and 850V and possess a maximum instantaneous average junction operating temperature of 50 to +150 degrees Celsius. Peak forward voltage drop characteristics are provided alongside peak surge current ratings and power dissipation limits.
Non-Controlled Avalanche Rectifiers cover a wider range with maximum reverse voltage (VRRM) ratings of 50V up to 1000V, including values at 100V, 200V, 400V, 600V, 800V, and suitable for operation within the same thermal range as their controlled counterparts. The datasheet reveals a detailed depiction of voltage drop conditions under differing temperatures and forward current scenarios.
The Fast Recovery Types are defined by a maximum recovery time of 200 nanoseconds, demonstrating rapid transition capabilities from conducting to non-conducting states. These rectifiers also operate within a broad junction temperature range and emphasize efficiency in applications demanding quick switching.
Detailed Specifications and Performance Data
Maximum ratings, including forward current, power dissipation, and peak surge current, are specified for each type of rectifier. Additionally, the datasheet provides recovery time data, thermal characteristics, and peak repetitive reverse voltage metrics for a comprehensive understanding of each rectifier’s capabilities. Graphs and charts illustrate performance aspects such as forward current vs. ambient temperature and instantaneous forward voltage drop, supporting engineers in assessing components for their specific needs.
