Wavelength-sensitive photodiode C30737LH-500-92N

avalancheLIDARsilicon

Product overview
The C30737LH-500-92N is a silicon avalanche photodiode (Si APD) featuring a 500 µm active diameter in a leadless ceramic carrier (LCC) with a 905 nm optical bandpass window and enhanced response near 900 nm. It is intended for photon detection in LiDAR, rangefinding and similar high-speed optical systems.

Key features

• Active diameter: 500 µm
• 905 nm optical bandpass filter for narrowband detection
• Enhanced responsivity around 900 nm (60 A/W at 900 nm)
• Low noise with noise current ~0.1 pA/√Hz
• Fast temporal response: rise/fall time 0.9 ns (Rload = 50 Ω) and cut-off frequency ≈ 380 MHz
• Available in leadless ceramic carrier (LCC) with 3×3 mm glass window

Applications

• LiDAR and airborne/terrestrial ranging
• Laser range-finding and time-of-flight sensors
• Security and scanning systems
• Cost-sensitive photodetection solutions requiring high-speed response
