PACKAGE DIMENSIONS

NOTES:

1

Dimensions are in inches.

2

Millimeters are given for general information only.

3

Refer to rules for dimensioning Semiconductor Product Outlines included in Publication No. 95.

4

Lead number 4 and 8 omitted on this variation.

5

TW must be held to a minimum length of .021 inch (0.53 mm).

6

LL measured from maximum HD.

7

Details of outline in this zone optional.

8

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

9

Leads at gauge plane .054 - .055 inch (1.37 - 1.40 mm) below seating plane shall be within .007 (0.18 mm) radius of true

position (TP) at a maximum material condition (MMC) relative to the tab at MMC. The device may be measured by direct

methods or by the gauge and gauging procedure described on gauge drawing GS-1.

10

LD applies to LL minimum.

11

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

12

For transistor types 2N3810 and 2N3811, LL is .500 inch (12.70 mm) minimum, and .750 inch (19.05 mm) maximum. (TO-

78).

13

For transistor types 2N3810L and 2N3811L, LL is 1.500 inches (38.10 mm) minimum, and 1.750 inches (44.45 mm)

maximum.

14

In accordance with AMSE Y14.5M, diameters are equivalent to

φx symbology.

15

Leads 3 and 5 = emitter, leads 2 and 6 = base, leads 1 and 7 = collector.
