The new photorelay is upwards compatible with the earlier TLP172A, in terms of both performance and footprint. As the TLP176AM is normally-open, it is suitable for use as a replacement for 1-Form-A mechanical relays.
By replacing mechanical relays with photorelays system reliability is improved and the space required for relays and relay drivers is reduced. As TLP176AM has a rated operating temperature between -40°C and 110°C it is suitable for industrial applications and easier to allow a temperature margin in system-level thermal design.
The device offers fast switching times of 3 ms (tON) and 0.5 ms (tOFF) with an isolation voltage of 3750 Vrms. It is housed in a small 4-pin SO6 package and fully approved to UL1577 for safety-critical applications.
