SEMTECH I CORPORATION 652 Mitchel! Road, Newbury Park, California 91320 (805) 498-2111, (213) 628-5392 / TWX: 910-336-1264 KILOVOLT-STAC HIGH VOLTAGE SILICON RECTIFIERS The Semtech KILOVOLT-STAC is a new high density, high voltage, silicon rectifier for use in commercial, industrial and military applications. Designed and tooled to be efficiently mass produced, "KILOVOLT-STAC can be used economically in existing applications. The rectifier can be utilized in all standard, single and polyphase rectifier circuits and is specifically adaptable for use in power supplies for X-ray equipment. These devices are cylindrical in shape and thereby provide easy mounting in either air or oil. Designed to be corona-free, KILOVOLT-STAC rectifiers are capable of meeting stringent electrical, mechanical and environmental specifications. @ 100MA SCKV100K3 100 1 25 0.1 0.2 0.3 168 7.5 4.50 SCKV150K3 150 1 25 0.1 0.2 0.3 252 7.5 6.63 SCKV200K3 200 1 25 0.1 0.2 0.3 336 75 8.75 @ 100 MA SCKV50K6 50 1 25 0.2 0.4 0.6 84 15 4.50 SCKV75K6 75 1 25 0.2 0.4 0.6 126 15 6.63 SCKV100K6 100 1 25 0.2 0.4 0.6 168 15 8.75 @ 100 MA SCKV33K12 33 1 25 0.3 0.6 1.2 56 20 4.50 SCKV45K12 45 1 25 0.3 0.6 1.2 84 20 6.63 SCKV66K12 66 1 25 0.3 0.6 1.2 112 20 8.75 @ 500 MA SCKV12.5K30 12.5 1 25 1.0 2.0 3.0 14 50 4,50 SCK18K30 18 1 25 1.0 2.0 3.0 21 50 6.63 SCKV25K30 25 1 25 1.0 2.0 3.0 28 50 8.75 @ 1 AMP SCKV12.5K40 12.5 1 25 1.0 2.0 4.0 14 150 4.50 SCKV18K40 18 1 25 1.0 2.0 4.0 21 150 6.63 SCKV25K40 25 1 25 1.0 2.0 4.0 28 150 8.75 Operating and Storage Temperature 55C to +150C. TECHNICAL BULLETIN H60 * Atmosphere and operating voltage must be consistent with length of stack. For higher current ask for KW-PAC high voltage silicon rectifiers TUBE-PAC HIGH VOLTAGE SILICON RECTIFIERS TUBE-PAC is Semtechs new line of silicon, high-voltage rectifiers intended as a direct plug- in replacement part for most popular mercury-vapor and vacuum glass tube-type rectifiers. Designed to last the life of the equipment, Semtech's TUBE-PAC are smaller, corona-free, di-sipate heat more effectively and eliminate filament power. No special adaptors are re- quired to use Semtechs TUBE-PAC. STR (SEMTECH TUBE REPLACEMENT PRECEEDS STANDARD EIA TUBE TYPE NUMBER).
