Extraction of the Resistance, Saturation Current
and Ideality Factor
The PG0035 and PG0036 have a maximum DCR of 93 milliohms, a saturation current
rating of 6 ADC, and a heating current rating of 3 ADC.
This includes inductance ranging from 0.10 to 47 microhenries, current ratings from 575 to 3,100 milliamperes, and saturation current
up to 4,500 milliamps.
The others increase with temperature, such as the short-circuit current, which slightly increases, and the reverse saturation current
which increases exponentially [11-14].
The thin oxide layer is effective for reducing the reverse saturation current
and thus improves the device property .
By working with [DELTA][V.sub.BE] instead of [V.sub.BE], [I.sub.S]--the reverse-bias saturation current
in the Shockley diode equation--is eliminated in the math, as shown in equation 1.
But the reverse saturation current
varies dynamically with respect to irradiance.
where [I.sub.0] is the reverse saturation current
, and [V.sub.T] = kT/q is the temperature voltage ([V.sub.T] [approximately equal to] 26 mV at room temperature).
This is part of a family of ultra-low-noise, dual JFETs positioned to provide users better-performing, wider bandwidths and cheaper solutions for obtaining tighter IDSS (drain-source saturation current
) matching and better thermal tracking than matching individual JFETs.
