Product details

Switching speed and isolation rating

The TLP2309(TPR,E is a single-channel DC-input transistor-output optoisolator rated for 3750 Vrms isolation — a common basic-insulation level for industrial interfaces, PLC digital inputs, and comms port isolation where the bus wiring is exposed to ground shifts. Typical turn-on and turn-off times are both 1 µs (1 µs max).

Temperature range and output drive

Operating temperature spans -40°C to 110°C, which covers factory-floor and outdoor telecom enclosures but stops short of the -55°C to 125°C range of the TLP109(TPR,E — so if the BOM calls for a 125°C top end, the TLP109 family is the closer fit. Maximum output current per channel is 8 mA at a 20 V output ceiling; the minimum current transfer ratio is 15% at 16 mA forward current.

Frequently asked questions

What is the turn on/off time of TLP2309(TPR,E)?

Typical turn-on and turn-off times are both 1 µs, with a 1 µs maximum.

What is a suitable replacement for TLP2309(TPR,E?

The closest functional second-source is the TLP2309(E), which shares the same DC input, transistor output, 3750 Vrms isolation, and 1 µs switching but ships in a tube package instead of Tape & Reel. For faster switching, the TLP109(IGM-TPL,E offers 450 ns typical; for a wider temperature range, the TLP109(TPR,E covers -55°C to 125°C.

Is TLP2309(TPR,E RoHS compliant?

Yes — it is listed as RoHS Compliant.
