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 L1 and L2. Dimension LD applies between L2 and LL minimum. Diameter is uncontrolled in L1 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 x 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.

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 x symbology. Symbol BL BL2 BW BW2 CH L3 LH LL1 LL2 LS LW LW2 Pin no.
