No Suffix denotes +10% tolerance, "C" suffix denotes +2% tollerance and "D" suffix denotes +1% tolerance. NOTE 2: Zener voltage is measured with the device junction in thermal equilibrium at an ambient temperature of 25C + 3C. NOTE 3: Zener impedance is derived by superimposing on IZT A 60Hz rms a.c. current equal to 10% of IZT Revision Date: 11/4/2009 New Product 1 1N746 thru1N759A & 1N4370 thru1N4372A (Including -1 Versions) Outline Drawing LEADED DESIGN DATA 0.080 MAX 2.03 DIA CASE: Hermetically sealed, DO - 35 1.000 MIN 25.400 LEAD MATERIAL: Copper clad steel LEAD FINISH: Tin / Lead POLARITY BAND (CATHODE) 0.175 MAX 4.44 0.018 / 0.022 DIA 0.457 / 0.559 1.000 MIN 25.400 THERMAL RESISTANCE: (RJEC): 250 C/W maximum at L = .375 in THERMAL IMPEDANCE: (ZJX): 35C/W maximum POLARITY: Diode to be operated with the banded (cathode) end positive MOUNTING POSITION: Any All dimensions in INCH mm Graphs ISO 9001: 2008 certified companies Aeroflex / Metelics, Inc. 975 Stewart Drive, Sunnyvale, CA 94085 Tel: (408) 737-8181 Fax: (408) 733-7645 54 Grenier Field Road, Londonderry, NH 03053 Tel: (603) 641-3800 Fax: (603)-641-3500 Sales: 888-641-SEMI (7364) Hi-Rel Components 9 Hampshire Street, Lawrence, MA 01840 Tel: (603) 641-3800 Fax: (978) 683-3264 www.aeroflex.com/metelics-hirelcomponents www.aeroflex.com/metelics metelics-sales@aeroflex.com Aeroflex / Metelics, Inc. reserves the right to make changes to any products and services herein at any time without notice.
