Note) 1. Measuring methods are based on JAPANESE INDUSTRIAL STANDARD JIS C 7031 measuring methods for diodes.
2. Cutoff frequency: 30 MHz
fC : 10 × log
PO at f = fC
= 3
PO at f = 1 MHz
3. A light detection element uses a silicon diode have proofread a load with a standard device.
4. LED might radiate red light under large current drive.
