Toshiba Releases Small Photorelays with 135°C Rating for High-Temperature Equipment Operation
Toshiba Electronic Devices & Storage Corporation
("Toshiba") has launched four voltage-driven photorelays,
“TLP3407SRB,” “TLP3412SRB,“ ”TLP3412SRHB,“ and “TLP3412SRLB” housed in the
small S-VSON4T package. The new photorelays deliver a maximum operating temperature
rating of 135°C for equipment that operates at high temperatures. Volume
shipments start today.
Advances in electrification and autonomous driving now
require high-density packaging of electronic components in automotive
equipment. This has raised the temperatures at which automotive semiconductors
operate, and testing under similar conditions is necessary to evaluate
reliability; testers, burn-in equipment, probe cards, and other devices for
automotive semiconductors must be able to operate at high temperatures, as must
the photorelays used in them.
The maximum operating temperature of Toshiba’s new products has
been pushed from the 125°C of current products to 135°C by optimising the
design of built-in elements. In addition, because they are voltage-driven type
photorelays with built-in resistors on the input side, no external resistor is
required, reducing space requirements on mounting boards. They are also housed
in a small package, the S-VSON4T, which is 1.45 × 2.0 mm (typ.).
The combination of these factors makes the new photorelays
suitable for application in automotive semiconductor testers, probe cards, and
burn-in equipment, where multiple photorelays need to be mounted within a
limited board space, and reliable high-temperature operation is required.
Toshiba will continue to offer a lineup of products that
support high-temperature operation in equipment.
