OSD1-4T

The OSD1-4T is designed as photodetectors which are a lower cost series offering good responsivity out to 1150 nm and low capacitance. They are restricted to a maximum of 100 volts operation and hence exhibit a slower pulsed response at longer wavelengths.

Some absolute maximum ratings of OSD1-4T have been concluded into several points as follow. The first one is about its DC reverse voltage which would be 120V. The second one is about its peak pulse current (1uS, 1% duty cycle) which would be 200mA. The third one is about its peak DC current which would be 10mA. The fourth one is about its storage temperature range which would be from -45°C to +100°C. The fifth one is about its operating temperature range which would be from -25°C to +75°C. The sixth one is about its soldering temperature for 5 seconds max which would be 200°C.

Also some electrical specifications of OSD1-4T (characteristics measured at 22°C ambient, and a reverse bias of 100 volts, unless otherwise stated) have been concluded into several points as follow. The first one is about its active area which would be 1mm2 and 1.13mm dia. The second one is about its responsivity which would be min 0.39A/W and typ 0.47A/W. The third one is about its dark current which would be max 0.25uA and typ 0.01uA. The fourth one is about its NEP WHz-1/2 which would be typ 2.4 x 10^-13. The fifth one is about its capacitance which would be 7pF at Vr=0V and would be 2pF at Vr=160V. The sixth one is about its risetime which would be typ 44ns. The seventh one is about its package which would be 1. It should be noted that recommended operating voltage range would be from 0 to 100V, for all series 4T detectors. And so on.
