Unit: mm
TLP291 consists of photo transistor, optically coupled to a gallium arsenide
infrared emitting diode. TLP291 is housed in the SO4 package, very small
and thin coupler.
Since TLP291 is guaranteed wide operating temperature (Ta=-55 to 110 ˚C)
and high isolation voltage (3750Vrms), it’s suitable for high-density surface
mounting applications such as small switching power supplies and
programmable controllers.

1. If a printed circuit is incorporated, the creepage distance and clearance may be reduced below this value.
(e.g. at a standard distance between soldering eye centers of 3.5mm).
If this is not permissible, the user shall take suitable measures.
2. This photocoupler is suitable for ‘safe electrical isolation’ only within the safety limit data.
Maintenance of the safety data shall be ensured by means of protective circuit.
