Product details

3750Vrms isolation in a 4-SOIC footprint

Housed in a 4-SOIC package (4.55 mm body width), it fits standard surface-mount assembly flows and is offered in both Tape & Reel and Cut Tape options for prototype or production quantities.

CTR range and switching speed for drive margin

Current transfer ratio spans 50% min to 150% max at If=5 mA, Vce=5V — a 3:1 spread that lets the designer set the LED forward current to guarantee a logic-high at the output across temperature and device variation. Typical rise and fall times are 2 µs and 3 µs respectively, with turn-on and turn-off both at 3 µs — fast enough for 10-100 kHz switching in IGBT gate drive or isolated serial links, but not for high-speed digital isolation above 1 Mbps.

Frequently asked questions

What is the current transfer ratio (CTR) of TLP293(Y-TPL,E?

CTR is 50% minimum to 150% maximum, measured at If=5 mA and Vce=5V. This range allows the designer to select a forward current that guarantees the output transistor saturates across all operating conditions.

Can TLP293(Y-TPL,E replace PC817?

Both are single-channel transistor-output optocouplers in a 4-pin SOIC package, but the PC817 has a wider CTR bin spread and different pinout (base pin available on PC817, not on TLP293). Verify the CTR requirement and pin compatibility on your PCB before substituting. The TLP293 offers a tighter CTR range (50-150%) versus PC817's 50-600% across bins, which may simplify drive design.
