Known Good Die Photodiodes

Cosemi's photodiodes are ideal for high bandwidth optical networking applications for both short and long wavelengths. The devices offer high responsivity, low dark current, and low capacitance for today’s high performance receiver design. The devices are designed to have a high aperture to bandwidth ratio which often results in greater manufacturing production yields. Each device ships 100% tested and guaranteed to work.

Cosemi’s photodiodes are supplied in bare die form allowing for maximum packaging flexibility by our customers. The devices are ideally suited for datacom, telecom, consumer, and medical applications. Common applications are 4G ROSA, 10G ROSA, 10G SFP+, 10G LRM, chip to chip interconnects, QSFP and other active optical cable standards. All products are Telcordia-qualified and guaranteed by Cosemi's proprietary SureOptical quality process. Our products have been tested with most leading TIA vendors and are in production with most of the leading 10G TOSA and 10G ROSA manufacturers.
