TRANSISTOR IDENTIFICATION identified by a JAN designation printed
directly on the case of the transistor. If in doubt about a transistor's markings,
always replace a transistor with one having identical markings, or consult an
equipment or transistor manual to ensure that an identical replacement or
substitute is used.
TESTING A TRANSISTOR to determine if it is good or bad. Can be done with
an ohmmeter or transistor tester or by the substitution method.
PRECAUTIONS - should be taken when working with transistors since they are
TRANSISTOR LEAD IDENTIFICATION - plays an important part in transistor
maintenance because before a transistor can be tested or replaced, its leads
must be identified. Since there is NO standard method of identifying transistor
leads, check some typical lead identification schemes or a transistor manual
before attempting to replace a transistor.
