Title
(EN) OPTOELECTRONIC DEVICE ELECTROSTATIC DISCHARGE PROTECTION
(FR) PROTECTION D'UN DISPOSITIF OPTOELECTRONIQUE CONTRE UNE DECHARGE ELECTROSTATIQUE
Abstract
(EN)
A method and apparatus for electrostatic discharge protection for an optoelectronic device (102, 202) driven by an electrical link driver is provided. An AC coupled positive output of a differential mode electrical link driver is wire-bonded to an electrostatic discharge protector. The electrostatic discharge protector (104) includes dual diodes (210, 212) for discharging electrical current resulting from an electrostatic discharge. In one embodiment, the electrostatic discharge protector (104) protects the optoelectronic device (102, 202) from a 2kV discharge per the human body- mode 1.
(FR)
La présente invention concerne un procédé et un appareil destinés à une protection contre une décharge électrostatique pour un dispositif optoélectronique entraîné par un circuit de commande à liaison électrique. Une sortie positive couplée au courant alternatif d'un circuit de commande à liaison électrique en mode différentiel est reliée par câble à un dispositif de protection contre une décharge électrostatique. Ledit dispositif de protection comprend deux diodes destinées à décharger le courant électrique résultant d'une décharge électrostatique. Dans un mode de réalisation, ledit dispositif de protection protège le dispositif optoélectronique d'une décharge de 2 kV à travers le modèle de corps humain.
