Junction Temperature Calculation
MTTF is inversely proportional to the device junction
temperature. For junction temperature and MTTF consid-
erations the device operating conditions should also
satisfy the following expression:
PDC < (TJ - TL) / RTH
where:
PDC = IDS * VDS (W)
TJ = Junction Temperature (C)
TL = Lead Temperature (pin 2) (C)
RTH = Thermal Resistance (C/W)
Biasing Details
The SPF-3043 is a depletion mode FET and requires a
negative gate voltage to achieve pinchoff. As such, power
supply sequencing circuitry is strongly recommended to
prevent damaging bias transients during turn-on. Active
bias circuitry is also recommended to maintain a constant
drain current from part-to-part.

Operation of this device beyond any one of these limits may cause
permanent damage. For reliable continuous operation, the device voltage
and current must not exceed the maximum operating values specified in the
table on page 1.
