Special Sun AHM Technology(Shanghai)Co.,Ltd.
SPS - ISO Factory for SMD and through-hole Diodes and Rectifiers since 2000

SPS popular Axial Diodes Rectifiers:

DO-15 1N5391 THRU 1N5399 (1N5391, 1N5392, 1N5393, 1N5395, 1N5397, 1N5398,1N5399) General Purpose Plastic Rectifier

DO-41 Glass 1N4728A-1N4739A-1N4764A 3.3V to 100V Silicon Epitaxial Planar Zener Diodes

DO is an abbreviation of "diode", and 41 and 15 are package serial numbers.

the difference between DO-41 and DO-15 is as follows:

1. Different production specifications:

DO-41 Diode body straightness diameter is in the range of 2.0mm ~ 2.7mm, the Length of the diode body is between 4 ~ 5.2mm, the diameter of the two Ends of the pin is between 0.71mm ~ 0.86mm, and the overall length is 25.4mm.

the diameter of DO15 diode body is in the range of 4.8mm ~ 5.3mm, the length of the diode body is between 7.2mm ~ 9.5mm, the diameter of the pin on both ends is between 1.2mm ~ 1.32mm, the Overall length is also 25.4mm.

2. the chip load capacity is different:

DO-41 Has large inner and outer diameters, thicker leads, and better heat Dissipation. It is used to seal larger 1.0W chips; DO-15 has smaller Inner and outer diameters, thin plug leads, and is often used to package Chips with ≤0.5W.

the common package types of diodes are as follows:
DO-15, DO-41, DO-27, SOD-323, SOD-523, SOD-723, SOT-23, SOT-323, SOT-523 and other packaging forms.
