AEC-Q101 Qualified High Voltage Thyristors and Diodes

402

Vishay Intertechnology, Inc. introduced 37 new high voltage thyristors and diodes for automotive applications. Qualified to AEC-Q101, the Vishay Semiconductors devices offer repetitive voltages from 600 V to 1600 V and wide current ranges in three package options.

The devices released today are available in surface-mount DPAK (TO-252AA) and D²PAK (TO-263AB) packages and in the through-hole TO-247AD. The nine new thyristors deliver continuous RMS on-state current from 12 A to 79 A, while the 28 standard and fast recovery diodes offer forward current from 8 A to 65 A. All devices provide up to 1000 V/µs immunity.

The thyristors and diodes are designed for use in the 50 Hz / 60 Hz AC line rectification stage for on-board battery chargers in electric vehicles (EV) and hybrid electric vehicles (HEV), where they supply a full range of charging power from 3 kW to over 30 kW. For inrush current limiting, the thyristors enable soft start functionality without the use of resistors and bulky mechanical relays.
