Product details

Four isolation channels in one SO-16 package

The Toshiba TLP293-4(E packs four independent phototransistor optocouplers into a single 16-SO (0.179", 4.55mm width) surface-mount package. Each channel provides 3750Vrms galvanic isolation between a DC-input LED and a phototransistor output, with a current transfer ratio (CTR) guaranteed between 50% and 600% at a forward current of 5mA. The output transistor is rated for 80V collector-emitter and 50mA continuous current, with a maximum saturation voltage of 300mV.

Switching speed and timing budget

Typical rise and fall times are 2µs and 3µs respectively, with turn-on and turn-off times both at 3µs.

Frequently asked questions

What is the CTR of TLP293-4(E?

The current transfer ratio (CTR) is specified as 50% minimum and 600% maximum at a forward current of 5mA. This wide range means the part can accommodate different LED drive strengths while still guaranteeing a logic-level output at the collector.

TLP293-4(E vs TLP293-2 comparison

The TLP293-4(E is a quad-channel (4-channel) version; the TLP293-2 is a dual-channel (2-channel) variant. Both share the same 3750Vrms isolation, 50-600% CTR, 80V output rating, and SOIC package family. The choice is simply how many isolated channels you need per package — the quad saves board space when you need four, the dual is more economical when you need only two.
