This specification is approved for use by all Departments
and Agencies the Department of Defense.
1. SCOPE
1.1 Scope. This specification covers the performance requirements for unitized, dual transistors which contain a
pair of electrically isolated complementary NPN and PNP silicon triode transistors in one package. Three levels of
product assurance are provided for each device type as specified in MIL-PRF-19500.
1.2 Polarity designation. Voltages and currents of limits and test conditions shown herein apply to the NPN triode.
For the PNP triode, the values are the same, but the polarity designations shall be the opposite.
1.3 Physical dimensions. See figures 1 (6 lead flatpak), 2 (similar to T0-77), and 3 (surface mount).
1.4 Maximum ratings.

(1) TC rating do not apply to surface mount devices (2N4854U).
(2) For TA > +25 C, derate linearly 1.43 mW/ C one transistor, 2.00 mW/ C both transistors.
(3) For TA > +25 C, derate linearly 1.71 mW/ C one transistor, 3.43 mW/ C both transistors.
(4) For TC > +25 C, derate linearly 4.0 mW/ C one transistor, 8.0 mW/ C both transistors.
(5) For TC > +25 C, derate linearly 5.71 mW/ C one transistor, 11.43 mW/ C both transistors.
