Lead Form Dimensions

M2

The TO-202AB, TO-220AB, and TO-92 package configurations,

because of their unique design, can be mounted in a variety of

methods, depending upon heat sink requirements and circuit

packaging methods. Any of the derived types shown in this sec-

tion are available as standard parts direct from the factory. Cus-

tom package variations are available. Consult the factory for

more information.

To designate lead form options, simply indicate the type number

at the end of the Teccor standard part number.

Example: Q2004F312 (Signifies Type 12)

Note: When ordering a TO-202 F package, include a 1 for stan-

dard full tab package. When ordering anything other than full tab,

remove the 1 and add the Lead Form Type.

See “Description of Part Numbers” in the Product Selection

Guide of this catalog for a complete description of Teccor part

numbers.

Lead Bending Specifications

Leads may be bent easily and may be bent to any desired angle,

provided that the bend is made at a minimum 0.063" (0.1 for

TO-218) away from the package body with a minimum radius of

0.032". DO-15X device leads may be bent with a minimum radius

of 0.050", and DO-35 device leads may be bent with a minimum

radius of 0.028". Leads should be held firmly between the pack-

age body and the bend, so that strain on the leads is not trans-

mitted to the package body.

When bending leads in the plane of the leads (spreading), bend

only the narrow part.

Sharp angle bends should be done only once, as repetitive bend-

ing will fatigue and break the leads.
