Outline Drawing (TO-18):
NOTES:
1. Dimensions are in inches.
2. Millimeters are given for general information only.
3. Beyond r (radius) maximum, TL shall be held for a minimum length
of .011 inch (0.28 mm).
4. Dimension TL measured from maximum HD.
5. Body contour optional within zone defined by HD, CD, and Q.
6. 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.
7. Dimension LU applies between L
1
and L
2
. Dimension LD applies
between L
2
and LL minimum. Diameter is uncontrolled in L
1
and
beyond LL minimum.
8. All three leads.
9. The collector shall be internally connected to the case.
10. Dimension r (radius) applies to both inside corners of tab.
11. In accordance with ASME Y14.5M, diameters are equivalent to
φx
symbology.
12. Lead 1 = emitter, lead 2 = base, lead 3 = collector.
13. For L suffix devices, dimension LL = 1.5 inches (38.10 mm) min.
and 1.75 inches (44.45 mm) max.

Outline Drawing (UA surface mount):
NOTES:
1. Dimensions are in inches.
2. Millimeters are given for general information only.
3. Dimension CH controls the overall package thickness. When a
window lid is used, dimension CH must increase by a minimum of
.010 inch (0.254 mm) and a maximum of .040 inch (1.020 mm).
4. The corner shape (square, notch, radius) may vary at the
manufacturer's option, from that shown on the drawing.
5. Dimensions LW2 minimum and L3 minimum and the appropriate
castellation length define an unobstructed three-dimensional space
traversing all of the ceramic layers in which a castellation was
designed. (Castellations are required on the bottom two layers,
optional on the top ceramic layer.) Dimension LW2 maximum and
L3 maximum define the maximum width and depth of the
castellation at any point on its surface. Measurement of these
dimensions may be made prior to solder dipping.
6. The co-planarity deviation of all terminal contact points, as defined
by the device seating plane, shall not exceed .006 inch (0.15mm) for
solder dipped leadless chip carriers.
7. In accordance with ASME Y14.5M, diameters are equivalent to
φx
symbology.
