JANS 2N7389
Qualified Levels:
JANSR and JANSF
Radiation Hardened P-Channel MOSFET
Qualified per MIL-PRF-19500/630
DESCRIPTION
Microsemi’s first generation Rad- Hard MOSFET’s are designed for Space and Military
applications. The devices have been characterized for Total Dose (TID) and Single Event
environments (SEE). These products may be used for satellite Power Supplies, Motor
Controls and any miscellaneous power applications needed for Space. Microsemi’s Rad- hard
MOSFET’s are qualified to MIL-PRF- 19500 slash sheet specifications. The 2N7389 is
qualified to meet Slash Sheet /630 of MIL-PRF-19500.

SYMBOLS & DEFINITIONS
Definition
Rate of change of diode current while in reverse-recovery mode, recorded as maximum value.
Drain Current, dc: The direct current into the drain terminal.
Zero-Gate-Voltage Drain Current: The direct current into the gate terminal when the gate-source voltage is zero.
Forward Current: The current flowing from the p-type region to the n-type region.
Reverse-Gate Current, Drain Short-Circuited to Source: The direct current into the gate terminal with a forward gate
source voltage applied (I
GSSF
) or reverse gate source voltage applied (I
GSSF
) and the drain terminal short-circuited to
the source terminal.
Source Current, dc: The direct current into the source terminal.
Static Drain-Source On-State Resistance: The dc resistance between the drain and source terminals with a specified
gate-source voltage applied to bias the device to the on state.
Gate Drive Impedance or Gate Resistance.
Drain-Source Breakdown Voltage: Gate short-circuited to the source terminal.
Drain-Supply Voltage, dc: The dc supply voltage applied to a circuit connected to the drain terminal.
Drain-Gate Voltage, dc: The dc voltage between the drain and gate terminals.
Drain-Source Voltage, dc: The dc voltage between the drain terminal and the source terminal.
Drain-Source On-State Voltage: The voltage between the drain and source terminals with a specified forward gate-
source voltage supplied to bias the device to the on-state.
Gate-Source Voltage, dc: The dc voltage between the gate terminal and the source terminal.
