Product details

10 Mbps open-collector optoisolator with 5 kVrms isolation

The FOD8163T is a single-channel optoisolator from onsemi that switches at 10 Mbps with an open-collector Schottky-clamped output. That data rate covers Profibus, DeviceNet, and many industrial backplane buses without stretching the bit period. The 5 kVrms isolation rating meets reinforced insulation requirements per IEC 60950-1, so this part can sit on the safety barrier in a motor drive or a medical patient interface without additional optocouplers.

Fast edges and high transient immunity for noisy environments

The 20 kV/µs minimum common-mode transient immunity means the output won't glitch when a 600 V IGBT switches next to the opto — a real concern in inverter stages where the ground plane bounces at tens of kV/µs.

Active production, ROHS3 compliant, 6-SOIC package

It is ROHS3 compliant, so no exemption expiry risk for EU-shipped products. The surface-mount footprint is the same as a standard SO-6 wide-body, so layout reuse from other 6-pin optoisolators is straightforward.

The output side runs from 3 V to 5.5 V, covering 3.3 V and 5 V logic families directly — no level shifter needed. The input LED forward voltage is 1.45 V typical with a maximum forward current of 25 mA, so a 3.3 V CMOS output with a 100 Ω series resistor drives it comfortably.

Frequently asked questions

What is the difference between the FOD8163T and the FOD8162T?

The FOD8163T and FOD8162T are both single-channel open-collector optoisolators in the same 6-SOIC package from onsemi. The primary difference is data rate: the FOD8163T is rated for 10 Mbps, while the FOD8162T is a slower part typically rated at 1 Mbps. For a 10 Mbps bus, the FOD8163T is the correct choice; the FOD8162T would not meet the timing margin.

How do I test the FOD8163T on the bench?

Apply 3.3 V or 5 V to the output supply pin (Vcc) with a 10 kΩ pull-up resistor to the same rail on the output. Drive the input LED with a 1.45 V forward voltage at 10–15 mA through a series resistor. Toggle the input at 1 MHz and observe the output with an oscilloscope — expect 20 ns rise and 10 ns fall typical, with propagation delays under 90 ns. For isolation testing, use a hipot tester at 5 kVrms for 1 minute between input and output sides.
