MITSUBISHI PHOTO DIODES PD8XX2 SERIES InGaAs AVALANCHE PHOTO DIODES PD8042, PD8932, PD893D2 Feature DESCRIPTION PD8XX2 Series are InGaAs avalanche photodiodes which has a sensitive area of φ50µm. PD8XX2 is suitable for receiving the light having a wavelength band of 1000 to 1600nm. This photodiode features high-speed response and a high responsivity, and is suitable for the light receiving elements for optical fiber communication systems. φ50µm active diameter 1000~1600nm wavelength band Small dark current Low noise High responsivity APPLICATION Receiver for optical communication system ABSOLUTE MAXIMUM RATINGS <*1> Symbol Parameter Conditions Ratings Unit Ir Reverse current - 500 µA If Tc Forward curent - 2 mA Case temperature - -40 ~ +85 C Storage temperature - -40 ~ +100 C Tstg Note1: The maximum rating means the limitation over which the device should not be operated even instant time, and this does not mean the guarantee of its lifetime. As for the reliability,please refer to the reliability report from Mitsubishi Semiconductor Quality Assurance Department.

MITSUBISHI ELECTRIC As of Mar, 2002 MITSUBISHI PHOTO DIODES PD8XX2 SERIES InGaAs AVALANCHE PHOTO DIODES QUALITY ASSURANCE A range of the quality assurance is restricted as the product exposes the bare die to the external atmosphere, different from the conventional sealed package products. Regarding the quality assurance, please confirm to Mitsubishi Semiconductor Quality Assurance Section. PRECAUTIONS Some characteristics of this product may change depending on the user’s assembling condition. The system should be carefully designed so that problems do not occur. SAFETY PRECAUTIONS RELATING TO HANDOLING OF OPTICAL SEMICONDUCTOR DEVICE General: Although the manufacturer is always striving to improve the reliability of its products, problems and errors may occur with semiconductor products. Hence, it is required so that the user’s products are designed with full regard to safety by incorporating the redundancy, fire prevention, error prevention so that any problems or error with a semiconductor product does not cause any accidents resulting in injury or death, fire, or environmental damage. The following requirements must be strictly observed. Warning! 1. Handling of the product This product uses GaAs (gallium arsenate). In normal conditions this product is not toxic. or vaporized, its powder or vapor is dangerous to humans. this product. 2. However, if it is powdered Never attempt to crush, grind, bake or chemically treat Do not put this product into your mouth or swallow it. Discarding the product This product uses GaAs (gallium arsenate). It should be discarded as a specially controlled industrial waste, it should be separated from general industrial and household wastes, according to the “Law of Wastes and Cleaning”. Caution! 1. High temperature During operation the product may become hot. Therefore do not touch it directly during operation. The product will remain hot even after the power is turned off, so wait until it cools before you touch it. Otherwise burns may be caused. Never place any inflammable substance which may cause a fire near the product. There is a possibility that the specification is changed without notice.
