Vishay / Siliconix Featured Products

Vishay SQJ94xEP Automotive N-Channel 40V MOSFETs

Vishay Siliconix SQJ940EP and SQJ942EP are among the industry's first automotive-qualified dual MOSFETs in an asymmetric package. The device combines both high- and low-side MOSFETs required for high-efficiency synchronous DC / DC buck converters in one compact 5mm x 6mm PowerPAK SO-8L package. The size of the low-side MOSFET is increased to lower on-resistance and enables lower conduction losses for greater efficiency in synchronous buck converters. High temperature operation up to +175ºC provides the ruggedness and reliability required for demanding automotive applications.

Vishay Siliconix SiP32467/68 Slew Rate Controlled Load Switches

Vishay Siliconix SiP32467/68 Slew Rate Controlled Load Switches are slew rate controlled integrated high side load switches that operate in the input voltage range from 1.2V to 5.5V. This series of design features slew rate control, reverse blocking when switch is off, output discharge, and control logic pull up. The devices are logic low enabled. Typical applications include smart phones, GPS, portable media players, tablet computers, medical and healthcare equipment, industrial and instrumentation, and game consoles.

Vishay Siliconix SiP32454 Slew Rate Controlled Load Switch

Vishay Siliconix SiP32454 Slew Rate Controlled Load Switch is a slew rate controlled integrated high side load switch that operates in the input voltage range from 0.8V to 2.5V. The SiP32454 is N-channel MOSFET switching elements that provide 28mΩ switch on resistance. It has a 1ms at 1.2V and 1.5ms at 2.5V slow slew rate that limits the in-rush current and minimizes the switching noise. This load switch's low voltage logic control threshold can interface with low voltage control I/O directly without extra level shift or driver. A 2MΩ pull-down resistor is integrated at logic control EN pin. The SiP32454 integrates a switch OFF output discharge circuit.

Vishay Siliconix SiP32419/29 28V Load Switches

Vishay Siliconix SiP32419/29 28V Load Switches are load switches that integrate multiple control features that simplify the design and increase the reliability of the circuitry connected to the switch. Both devices are 56mΩ switches designed to operate in the 6V to 28V range. An internally generated gate drive voltage ensures good RON linearity over the input voltage operating range. The SiP32419/29 have a slew rate control circuit that controls the switch turn on time to the value set by an external capacitor. These devices feature a low voltage control logic interface which can be controlled without the need for level shifting. These devices also include a power good flag.

Vishay Siliconix Si1865DDL Load Switch with Level-Shift

Vishay Siliconix Si1865DDL Load Switch with Level-Shift includes a P- and N-channel MOSFET in a single SC70-6 package. The low on-resistance P-channel TrenchFET is tailored for use as a load switch. The N-channel, with an external resistor, can be used as a level-shift to drive the P-channel load-switch. The n-channel MOSFET has internal ESD protection and can be driven by logic signals as low as 1.5 V. The Si1865DDL operates on supply lines from 1.8V to 12V, and can drive loads up to 1.1A.

Vishay Siliconix DG141x Precision Quad SPST Analog Switches

Vishay Siliconix DG141x Precision Quad SPST Analog Switches are monolithic quad analog switches that are designed to provide high speed, low error switching of precision analog signals. Combining low power (0.033μW) with high speed (tON: 100ns), the DG141x family is ideally suited for portable and battery powered industrial and military applications. To achieve high-voltage ratings and superior switching performance, the DG141x series was built on Vishay Siliconix's newest high voltage silicon gate process. An epitaxial layer prevents latchup. Each switch conducts equally well in both directions when on, and blocks input voltages up to the supply levels when off.

Vishay Siliconix EF Series High Performance MOSFETs

Vishay Siliconix's EF Series High Performance MOSFETs are 600V super junction N-Channel power MOSFETs with a 30% reduction in specific On-Resistance versus the S Series MOSFETs. These feature a fast body diode MOSFET, using E Series technology, reduced Trr / Qrr / Irrm, low FOM, low input capacitance, low switching losses due to reduced Qrr, ultra low gate charge and are Avalanche Energy Rated (UIS). Typical applications include server and telecom power supplies, lighting, industrial, battery chargers, renewable energy and SMPS.
