TLP293(V4-GH,E – Optocoupler – Toshiba

The Toshiba TLP293(V4-GH,E is a single-channel, transistor-output photocoupler in a compact SO4 surface-mount package, rated for 3750 Vrms isolation and a wide -55 to +125°C operating range. Available for RFQ through Pacific Component Xchange.

The Toshiba TLP293(V4-GH,E is a low-input-current, high-isolation transistor-output photocoupler. It pairs an InGaAs infrared emitting diode with a silicon phototransistor inside a small, thin SO4 surface-mount package. This ordering variant denotes the VDE-qualified Option (V4) device, the GH (GRH) current-transfer-ratio rank, supplied in the RoHS-compatible/Pb-free version (E suffix).

With a guaranteed isolation voltage of 3750 Vrms (min) and a wide -55 to +125°C operating temperature range, the TLP293 is well suited to high-density surface-mount designs that demand robust primary-to-secondary isolation and reliable signal transfer.
