The 2SJ185 is a P-channel vertical type MOSFET which can be
driven by 2.5 V power supply.
The 2SJ185 is driven by low voltage and does not require
consideration of driving current, it is suitable for appliances
including VTR cameras and headphone stereos which need
power saving.
FEATURES
Directly driven by ICs having a 3 V power supply.
Not necessary to consider driving current because of its high
input impedance.
Possible to reduce the number of parts by omitting the bias
resistor.
Complementary to 2SK1399

Remark The diode connected between the gate and source of the transistor serves as a protector against ESD.
When this device actually used, an additional protection circuit is externally required if a voltage exceeding
the rated voltage may be applied to this device.
