Solid state relays (optical MOSFET based relays) | Vishay
Vishay’s solid-state relays (SSRs) are designed for high reliability, high input-to-output isolation, and low on-resistance. With small dimensions, low power consumption, and bounce-free operation, they offer many advantages compared to mechanical relays.
1 Form A Solid-State Relay LINKS TO ADDITIONAL RESOURCES DESCRIPTION The VO14642 is a high speed single channel normally open • solid-state relay (SPST - 1 form A) in a DIP-6 package. The relay is constructed as a multi-chip hybrid device. A high efficient infrared LED enables low forward current on the input side.
Solid-State Relay LINKS TO ADDITIONAL RESOURCES DESCRIPTION The VOM1271 is a stand-alone optically isolated MOSFET driver. Unlike conventional MOSFET drivers, which require an external power supply to provide VCC and or VDD rails to the driver itself, the VOM1271 obtains all the required
2022年3月12日 · 2. Do you have a low-cost SSR for use in place of EMRs? The 4-pin LH1546AEF/AD can be used, depending on your application requirements. Other possibilities include the LH1532FP and LH1550 products. 3. Can your SSRs meet my project’s requirement for an I/O voltage of at least 2500 V to 3000 V? Most of our SSRs provide an I/O voltage of …
1 Form A Solid-State Relay (Normally Open) LINKS TO ADDITIONAL RESOURCES DESCRIPTION The LH1510 is an SPST normally open switch (1 Form A) that can replace electromechanical relays in many applications. The relay is constructed using a GaAlAs LED for actuation control and high reliable MOSFETs for the output switch. FEATURES
A solid-state relay (SSR) is an electronic switching device in semiconductor technology. An SSR has a high efficient GaAlAs infrared emitter on the input which is optically coupled to the high performance MOSFETs at the output. An SSR is capable of switching AC loads where both output MOSFETs are required as well as DC loads where one
in the MOSFET SSR I-V characteristics and the on-resistance is extremely linear. The contact capacitance of a MOSFET SSR is higher than an open contact of an electromechanical relay. The majority of Vishay SSRs have LED inputs and monolithic switch outputs (figure 1). The switch is built using BiCMOS technology. Individual components are ...
