The invention relates to an optoelectronic component with a light emitting or light receiving element (1) and a system carrier (9) supporting the element (1). The element (1) emits or receives light on a light transmitting surface (1a), an auxiliary carrier (2) made of heat conductive material and transparent at least in some areas or at least translucent being provided. Said auxiliary carrier (2) is connected to the system carrier (9) and is thermally coupled to the element (1).

In an optoelectronic component having a laser chip as a light transmitter and a lens coupling optics for defined emission of radiation generated in the laser chip, the lens coupling optics is arranged immediately in front of the laser chip and is adjusted and fixed in stable fashion in a simple way. The component is rationally manufactured in a wafer union. The laser chip is arranged on a common carrier between two carrier parts whose lateral surfaces neighboring the resonator faces of the laser chip are provided with mirror layers, and that are inclined at an angle of 45.degree. relative to the resonator faces. Thus the radiation generated in the laser chip is directed nearly perpendicularly upward to the surface of the common carrier and the lens coupling optics is arranged on at least the one carrier part such that the radiation generated in the laser chip impinges this lens optics nearly perpendicularly.

An optical device includes a surface-mountable optical component with a base member having a recess filled with a transparent filler and a VCSEL element arranged in the recess. A receptacle is attached to the surface-mountable optical component. The receptacle is for receiving an optical fiber to optically connect the VCSEL element to the optical fiber. Accordingly, an inexpensive way of coupling a VCSEL element with an optical fiber is provided. In particular, the surface-mountable component can be produced using a high volume production so that the overall costs of the optical device are reduced, even if the receptacle is produced in lower numbers due to varying requirements in the way that the VCSEL will be coupled to an optical fiber.

A bidirectional transceiver module for message and signal transmission via a light waveguide is formed of a lens coupling optics, a laser chip as a light transmitter, a light receiver, and a beam splitter intervening in the beam path. These parts are at least partially surrounded by a housing. They are designed such that, given reduced manufacturing expense, a lens coupling optics arranged immediately in front of the laser chip can be adjusted in a simple way and can be fixed in stable fashion. The laser chip is arranged on a common carrier between two carrier parts whose lateral surfaces neighboring the resonator faces of the laser chip are provided with mirror layers and are inclined at an angle of approximately 45.degree. relative to the resonator faces for beam deflection onto the lens coupling optics secured above the laser chip on at least one carrier part. The mirror layer neighboring the front side of the laser chip is provided with the beam splitter. The light receiver or an optical coupling for this is provided at the underside of the common carrier.

An integrated semiconductor circuit has a component formed of a semiconductor substrate with an active pn junction formed between a first semiconductor region of a first conductivity type and a second semiconductor region of a second conductivity type. The semiconductor circuit also has a protective circuit that is associated with the component and serves to dissipate overvoltages and/or electrostatic charges. The protective circuit has a protective pn junction formed in a semiconductor mount with a first semiconductor mount region of the first conductivity type and a second semiconductor mount region of the second conductivity type. The second semiconductor mount region of the second conductivity type is electrically coupled to the first semiconductor region formed in the semiconductor substrate of the first conductivity type.
