U.L. REFCileO#GE7N16IZ39ED E7 TO-220 Isolated AC E7 General Description Teccor manufactures 15 A rms to 25 A rms rectifiers with voltages rated from 200 V to 1000 V. Due to the electrically-isolated TO-220 package, these rectifiers may be used in common anode or common cathode circuits using only one part type, thereby simplifying stock requirements. Teccor's silicon rectifiers feature glass-passivated junctions to ensure long term reliability and stability. In addition, glass offers a rugged, reliable barrier against junction contamination. Rectifiers (15 A to 25 A) RoHS Features • RoHS Compliant • Electrically-isolated packages • High voltage capabilities 200 V to 1000 V • High surge capabilities up to 350 A • Glass-passivated junctions ©2004 Littelfuse, Inc.
