D-PAK SCR Thyristor Flaunt +150°C Junction Temperature

Littelfuse’s SJ series high-temperature SCR thyristors are said to be the first circuit protection devices of their kind to offer a junction temperature of +150°C in compact surface-mount D-PAK (TO-252) packaging. The devices are also available in through-hole V-PAK (TO-251) packages. They have a gate current trigger level of 6 mA or 15 mA maximum at approximately 1.5V. Sensitive models in the series feature a gate trigger current of less than 200 μA. The sensitive devices can be easily triggered by sense coils, proximity switches, and microprocessors.

Applications for SJ Series SCR Thyristors include capacitive discharge ignition (CDI) systems for motorcycle engines, portable generator engine ignition, strobe lights and nailers, as well as generic rectifiers, battery voltage regulators, converters and inrush current limiting circuits in AC-DC converters. They are also ideal for use in controls for power tools, home/brown goods (such as consumer electronics like televisions, radios, digital media players, and computers) and white goods/appliances. For more details and specs, SJ series datasheets are available. Littelfuse Inc., Chicago, IL. 773-628-1000
