Lead bending of axial leaded devices prior to insertion into PC boards should not be in such close proximity to the body to force a bend up to and into the body itself. This excessive “tight bend” may stress glass body devices or transmit undesired forces internally into the active die element for plastic body devices as well. This is less critical on double slug glass diodes where the lead is welded or brazed to a larger diameter slug before entering a glass to metal seal region. In most examples a 90° bend should be at least 1/8” or three lead diameters from the body, which ever is greater. It is also recommended that leads be supported adjacent to the body before the bend is made.
