Hamamatsu Photonics launches the next generation in InGaAs PD

10 October 2025

Hamamatsu Photonics has released the G15978-0020P, a new indium gallium arsenide (InGaAs) photodiode (PD) representing the next step in miniaturized sensor technology. Designed for accurate distance measurement and low-light level detection applications, this device meets the demanding needs of research and development professionals, engineers, industrial applications and OEM customers alike.

The G15978-0020P boasts a surface-mount type chip-on-board (COB) package, making it significantlySource: Hamamatsu PhotonicsSource: Hamamatsu Photonics smaller than the previously available metal package type, G14858-0020AA. The G15978-0020P’s size is ideal for integration into compact and mobile equipment, facilitating advancements in various modern applications, and its enhanced sensitivity is suitable for such technologies as touchless displays, automatic faucets and free space communications.

Key features:

- Compact design: with dimensions of just 1.6 mm × 0.8 mm × 0.7 mm.

- Exceptional performance with low dark current: max 50 nA

- Low capacitance: Terminal capacitance (typ.) 2.0 pF

- Enhanced sensitivity: Peak sensitivity wavelength (typ.) 1550 nm, photosensitivity (typ.) 0.8 A/W.

- Compatible with lead-free reflow soldering, supporting higher reliability in harsh conditions and less harmful manufacturing processes

With a commitment to durability and reliability, the G15978-0020P is built with high-quality materials to withstand daily wear and tear, ensuring long-term performance. Additionally, the product is aligned with sustainable practices, avoiding the use of harmful materials in its composition, and aiding with adherence to RoHS directives.
