The new TLP176AM incorporates MOSFETs fabricated with the latest U-MOS IX process.
It has a rated on-state output terminal voltage (VON) of 60V and a constant on-state current (ION) of 0.7A with pulse operation up to 2.1 A.
At 3.75 kVrms, the new device provides higher ESD immunity than the current TLP172AM.
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 3ms (tON) and 0.5ms (tOFF) with an isolation voltage of 3750Vrms. It is housed in a small 4-pin SO6 package and fully approved to UL1577 for safety-critical applications.
