The tiny package makes the relay more densely placed in key space applications

   Toshiba Electronics Europe LTD offers three new 4-FORM-A voltage driven photoelectric relays with A minimum installation area.

    The new equipment has a wide range of applications, including measuring instruments, such as oscilloscope, data recorder and aging equipment. They are also applicable to semiconductor test equipment (memory probe card and test head, SOC and LSI). There are space constraints when multiple relays need to be installed on the circuit board.

   The new TLP3407SRA4, TLP3412SRHA4 and TLP3475SRHA4 are the company's first four-way 4-FORM-A relays. They are packaged in a very small, newly developed S-VSON16T package that measures just 2mm x 6.25mm x 1.3mm and requires 12.5mm2 PCB mounting area. Its area is about 14% smaller than the mounting area of four 1-channel relays

   New products in 3.3V or 5V systems can be driven entirely by voltage including input resistors without the need for external resistors. This further reduces the space requirements on the board, allowing more photo relays to be installed.

   All equipment is provided with normally open (1-form-a / no) configuration, with an off voltage of 60V and 300vrms (minimum) isolation. Tlp3412srha4 and tlp3475srha4 provide 250mA on state current. The typical on state resistance is only 1 ohm, while the corresponding figures of tlp3407sra4 are 600mA and 0.2 HM.

  The TLP3412SRHA4 and TLP3475SRHA4 typically open and close at only 220µs (tON) and 50µs (tOFF), making them ideal for high-speed testing and other similar applications.

  -40°C to +125° is within the operating temperature (Topr) range for all equipment. For high temperature applications while ensuring that the thermal design margin is met or exceeded.
