This specification is approved for use by all Departments
and Agencies of the Department of Defense.
1. SCOPE
1.1. Scope. This specification covers the performance requirements for NPN, silicon, transistors for use in
medium power switching applications. Four levels of product assurance are provided for each device type, and two
levels of product assurance for die (element evaluation) are provided, as specified in MIL-PRF-19500.
1.2. Physical dimensions. See figure 1 (similar to TO-5 for long leaded devices and TO-39 for short leaded
devices), figure 2, and figure 3 for JANHC and JANKC (die) dimensions.
1.3. Maximum ratings.
