![]() ![]() Note that in your specific case, the code you're looking for is probably just "331". In the 2N2222 NPN transistor, a single P-doped layer is embedded among two N-doped layers. This transistor is mainly designed for low power, low to medium current, medium voltage & works at fairly high speeds. If the manufacturer no longer exists, or has gotten bought up by another company decades ago, you're probably just out of luck. The 2N2222A transistor is a common NPN BJT & it is mainly used in the applications of switching & amplifying with less power. If they don't, you'd have to contact the manufacturer and ask. Este transistor tiene un encapsulado de metal TO-18 de 3 pines que son base, colector y emisor, donde el emisor se encarga de emitir o inyectar electrones, la base permite transferir o pasar los electrones y el colector se encarga de colectar. Even if you do know the manufacturer, these codes are meant mostly for the manufacturer's internal reference, so they might not be explained on the datasheet. 2N2222A es un transistor NPN de silicio diseñado para aplicaciones de conmutación. There is no standard, so without knowing the manufacturer, you're out of luck. But fitting that along with the part number on a TO-92 or TO-18, let alone a SOT-23 or SC-70, is pretty tough, so other codes are used instead. On parts with more room than a TO-92 or TO-18 provides, you might get a one-digit factory code for which factory the part was made in, combined with a four-digit date code consisting of the last two digits of the year and two digits indicating which week of the year it was made in. ![]() Supplyframe is committed to protecting and respecting your privacy, and weâll only use your personal information to administer your account and to provide the products and services you requested from us.The usual practice is to put some manufacturer-specific code that identifies which lot the device came from. ![]() But there are two important features that distinguish both. Fairchild became a leading supplier of power semiconductors, analog. The company was known for its innovation in the development of the first commercial transistor and for its contributions to the advancement of the integrated circuit technology.
