Toshiba Electronics Europe has launched three new photorelays: the TLP3407SRA, TLP3475SRHA and TLP3412SRHA. With a 2mm x 1.45mm footprint, they are among the smallest voltage-driven photorelays on the market and provide an extended operating temperature rating of 125C.
Raising the maximum operating temperature rating from 110C to 125C enables the photorelays to be mounted in high-temperature areas, making it simpler to secure necessary temperature design margins for equipment. The S-VSON4T package currently provides one of the smallest PCB mounting areas of 2.9mm2 and is just 1.3mm high. This compact size can contribute to decreasing PCB size or expanding the number of photorelays in an existing layout in applications including probe cards, semiconductor testers, burn-in equipment and other test and measurement equipment.
The TLP3407SRA provides a very small ON-resistance (RON) of typically 0.2Ohm, and an on/off switching current as high as 1A, making it excellent for switching applications in high-speed logic IC and memory testers. The device also offers a low input power consumption of 3.3mW.
The TLP3407SRA provides a built-in input resistance of 4000Ohm. The TLP3475SRHA and TLP3412SRHA built-in resistance is typically 600Ohm. This eradicates the necessity for an external input resistor, further lowering the overall design footprint. All devices also provide a low off-state current of 1nA at 50V and offered with low output pin capacitance of 80pF, 12pF and 20pF respectively.
