## What is the power gain of the OC-100 family devices?

The power gain is 2. This is the ratio of the output power of the photo diode divided by the input power to the LEDs. PTR = (10KV x 100mA) = 1 (5V x 100mA) .5 1/.5 = 2

## Can the current gain be increased?

No. The current gain is fixed.

## What is the current gain of the device?

The current gain of the device is 1/1000. This is the ratio of the output current (diode leakage current) divided by the forward current through the LED(s). CTR = 100mA = 10E-06 =. 001 = .1%. 100mA 10E-03

## Does the gain change with temperature?

Gain changes over temperature. Gain decrease as temperature increases. It is linear over the temperature range of –25C to +150C. VMI provides a graph of Gain vs. Temperature as part of the data sheet.

## Is it possible to get a 2W 10KV opto-coupler in the OC-100 style package?

In order to build a 2W opto-coupler, the number of LED’s would have to double, and there would have to be a way to remove the heat from the high voltage diode. It is not possible to do all of that and keep the package size the same. However, it is possible to connect...
