Laser diode

Abstract

The invention provides a laser diode comprising a diode cap at the top; a radiator and a laser diode die which are disposed in the diode cap; a laser diode die pin connected with the laser diode die; a photosensitive diode connected with the laser diode die pin; a photosensitive diode pin connected with the photosensitive diode; and a diode base disposed under the diode cap and outside the photosensitive diode. The laser diode die pin and the photosensitive diode pin are equipped with stopper blocks. The laser diode has beneficial effects that 1) the pins are not prone to be bent or fractured; and 2) it is uneasy to insert the inlaid pins excessively deeply and thus infirm soldering can be prevented.

Description

technical field [0001] The invention relates to a laser diode and belongs to the technical field of semiconductors. Background technique [0002] A diode is an electronic component, a device with two electrodes that only allows current to flow in one direction. Many uses are for its rectification function. The varactor diode (VaricapDiode) is used as an electronic adjustable capacitor. The current directionality of most diodes is usually called "rectifying" function. The most common function of a diode is to only allow current to pass in a single direction (called forward bias), and to block it when it is reversed (called reverse bias). So a diode can be thought of as the electronic version of a check valve. [0003] There are many types of diodes, which can be divided into germanium diodes (Ge tubes) and silicon diodes (Si tubes) according to the semiconductor materials used. According to their different uses, they can be divided into detection diodes, rectifier diodes,...

Problems solved by technology

[0005] 1) The pins are easily bent or broken;

[0006] 2) The pins are easy to be inserted too deep when inlaid, resulting in unstable welding

[0007] These shortcomings have seriously affected the service life of the diode
