NOTES:

1. Dimension are in inches.

2. Millimeters are given for general information only.

3. Beyond r (radius) maximum, TH shall be held for a minimum length of .011 (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. For 2N1893, dimension LL shall be 1.5 inches (38.1mm) minimum and 1.75 inches (44.4 mm) maximum.

12. For 2N1893S, dimension LL shall be .5 inch (12.7mm) minimum and .75 inch (19.0 mm) maximum.

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

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