2N6849U
Qualified Levels:
JAN, JANTX, JANTXV
and JANS
P-CHANNEL MOSFET
Compliant
Qualified per MIL-PRF-19500/564
DESCRIPTION
This 2N6849U switching transistor is military qualified up to the JANS level for high-reliability
applications. This device is also available in a thru hole TO-205AF package. Microsemi also
offers numerous other transistor products to meet higher and lower power ratings with various
switching speed requirements in both through-hole and surface-mount packages.

1. Derate linearly 0.2 W/°C for T C > +25 °C.
2. The following formula derives the maximum theoretical I D limit. I D is also limited by package and
internal wires and may be limited due to pin diameter.
