NOTES:

Dimensions are in inches.

Millimeters are given for general information only.

Beyond r (radius) maximum, TW shall be held for a minimum length of .011 (0.28 mm).

Dimension TL measured from maximum HD.

Body contour optional within zone defined by HD, CD, and Q.

CD shall not vary more than .010 inch (0.25 mm) in zone P. This zone is controlled for automatic handling.

Leads at gauge plane .054 +.001 -.000 inch (1.37 +0.03 -0.00 mm) below seating plane shall be within .007

inch (0.18 mm) radius of true position (TP) at maximum material condition (MMC) relative to tab at MMC.

The device may be measured by direct methods or by gauging procedure.

Dimension LU applies between L1 and L2. Dimension LD applies between L2 and LL minimum. Diameter

is uncontrolled in and beyond LL minimum.

All three leads.

10.

The collector shall be internally connected to the case.

11.

Dimension r (radius) applies to both inside corners of tab.

In accordance with ASME Y14.5M, diameters are equivalent to Φx symbology.

12.

13.

Lead 1 = emitter, lead 2 = base, lead 3 = collector.
