1. SCOPE
1.1 Scope. This specification covers the performance requirements for NPN, silicon, high speed switching
transistors (including dual devices). Four levels of product assurance are provided for each device type as specified
in MIL-PRF-19500, and two levels of product assurance are provided for each unencapsulated device type.
1.2 Physical dimensions. Figure 1 (TO-18) for 2N2369A and 2N3227, figure 2 (TO-46) for 2N4449, figure 3 for UB
version, figure 4 for UA version, figure 5 for U version (dual devices), and figure 6 and 7 (JANC).
