Wavelength-sensitive photodiode C30724EH

avalanchesiliconinfrared

Product overview
The C30724EH silicon avalanche photodiode (Si APD) delivers peak sensitivity at 920 nm in a hermetically sealed metal TO-18 package. It features a low temperature coefficient and fast response optimized for 905 nm laser ranging and related industrial sensing applications.

Series description
The C30724 series provides high responsivity across 800–950 nm with rise and fall times of approximately 5 ns and no fall-time tail. Designed for high-volume 905 nm laser range-finding, these APDs can be run at fixed bias without active temperature compensation.

Key features:

• Si APD with integrated 905 nm filter in metal TO-18 can
• ~5 ns rise and fall times, no trailing edge in fall time
• Operates at low gain
• Low temperature coefficient — no temperature compensation required

Key applications:

• Laser range finding
• Laser distance meters
• Traffic speed measurement
