Description
The popular 1N5283-1 thru 1N5314-1 and 1N7048-1
thru 1N7055-1 series of 0.5 watt current regulators
provides a selection from 0.22 mA to 10 mA in
standard 10% tolerances. These devices regulate
current over a broad voltage range as a counter part
offering to Zeners that regulate voltage over a broad
current range. The somewhat larger D0-7 packaging
option offers a double-plug internal bond connection
with a larger active die element for its unique
function as a current limiter.

4. t = 90s or thermal equilibrium for 1N5283 through 1N5314. t = pulse measurement, 10 ms max for 1N7048 through 1N7055
5. ZS is derived by superimposing a 90 Hz RMS signal equal to 10% of VS on VS.
6. ZK is derived by superimposing a 90 HZ RMS signal equal to 10% of VK on VK.
