Toshiba Electronics Europe GmbH<\/a><\/strong> has launched three new 4-Form-A voltage-driven photorelays with one of the smallest mounting areas in the industry.<\/p>\n\n\n\n

The new devices are suited to a wide range of applications including measuring instruments such as oscilloscopes and data loggers as well as burn-in equipment. They are also ideal for use in semiconductor test equipment (probe cards and test heads for memories, system-on-chip (SoC) and LSI) where there is a need to mount multiple relays on circuit boards with space constraints.<\/p>\n\n\n\n

The new products denoted TLP3407SRA4, TLP3412SRHA4 and TLP3475SRHA4 are Toshiba\u2019s first-ever four-circuit, 4-Form-A relays. They are housed in a tiny, newly developed S-VSON16T package measuring 2.0mm x 6.25mm x 1.3mm and requiring a PCB mounting area of just 12.5mm2. The area is approximately 14% less compared with the mounting area of four 1-channel relays.<\/p>\n\n\n\n

By incorporating input resistors, the new products are able to be voltage-driven without any need for external resistors in 3.3V or 5V systems. This further reduces space requirements on circuit boards, allowing more photorelays to be mounted.<\/p>\n\n\n\n

All devices are supplied in normally open (1-Form-A \/ NO) configuration with an off-state voltage of 60V and offer 300Vrms (min.) of isolation. The TLP3412SRHA4 and TLP3475SRHA4 offer an ON-state current of 250mA with a typical ON-state resistance of just 1\u03a9 while the corresponding figures for the TLP3407SRA4 are 600mA and 0.2\u03a9.<\/p>\n\n\n\n

With typical turn-on and turn-off times of just 220\u00b5s (tON) and 50\u00b5s (tOFF), the TLP3412SRHA4 and TLP3475SRHA4 are ideally suited to use in high-speed testers and other similar applications.<\/p>\n\n\n\n

The operating temperature (Topr) range for all devices is -40\u00baC to +125\u00baC, allowing use in high-temperature applications while ensuring thermal design margins are easily met or exceeded.<\/p>\n","protected":false},"excerpt":{"rendered":"
