This list is for use when an alternative to a metal can transistor is needed. To facilitate conversions on the most popular types National is offering the PN series, TO-92 devices that use the same die type and are screened to same electrical specifications, The TO-92 transistors produced by National Semiconductor are the most advanced Plastic Transistors ever manufactured. They utilize epoxy B encapsulation and a copper lead frame to give a power dissipation of up to 625 mW @ Ta = 25C. These transistors provide electrical pertorm- ance and reliability equivalent to their metal can versions in most applications where T; does not exceed 150C. The same situation is applicable to the TN series, except that the Nationai-originated TO-237 (TO-92 + ) case outline is used, which permits power dissipa- tion of up to 1.0W @ Ta = 25C. 18
