General
The TOSHIBA TLP3451 is a very small outline non-leaded photorelay suitable for surface-mount assembly. The
TLP3451 consists of an infrared LED optically coupled to a photo-MOSFET and is housed in a VSON 4-pin
package. The TLP3451 features low output capacitance, COFF, and thus fast on/off switching of a high-frequency
signal, making it ideal for switching applications in high-speed testers.
