SiC photodiodes offer deep-UV sensitivity with low dark current, making them perfect for flame sensing and environmental monitoring. Avalanche photodiodes provide internal gain for low-light applications such as lidar and long-range optical ranging. This diversity allows design engineers to select the exact photodiode technology that matches their system’s wavelength, speed, and noise requirements without compromise.

Beyond photodiodes, the company offers a full range of LED emitters covering UVC, UV, SWIR, red dot, and multi-wavelength configurations. UVC LEDs are increasingly used for sterilization and water purification, while SWIR LEDs find applications in machine vision and agricultural sorting. Red dot lasers are popular alignment aids in industrial equipment, and multi-wavelength LEDs enable compact spectrometers and color sensors. The sensor category includes reflective sensors, quadrant position detectors, and hybrid modules that combine multiple sensing elements in a single package. For detection needs, Zealnew provides PIN photodiodes, extended InGaAs detectors for beyond-standard SWIR wavelengths, and broadband detectors that cover ultraviolet through infrared. Packaging options are equally diverse, ranging from transfer-molded plastic packages for cost-sensitive consumer goods to hermetic SMD packages for harsh environments and chip-scale packages (CSP) for space-constrained designs. Each packaging technology is selected to balance optical performance, thermal management, and reliability for the target application.

Photodiodes form the backbone of countless optical sensing systems, converting light into electrical current with high fidelity. Silicon photodiodes are the workhorses of the industry, offering excellent responsivity from 400 nm to 1100 nm, low noise, and cost-effective manufacturing. InGaAs photodiodes extend sensitivity into the SWIR region up to 2.6 µm, enabling fiber optic communication, analytical instrumentation, and thermal imaging. SiC photodiodes are uniquely suited for UV detection below 280 nm where silicon becomes transparent, providing solar-blind operation ideal for flame detectors and corona discharge monitors. Avalanche photodiodes (APDs) incorporate an internal multiplication region that amplifies the photocurrent, delivering gain factors of 50 to 200 or more for single-photon counting and long-distance ranging. Each photodiode type is available in multiple active area sizes, package styles, and spectral response variants to match specific system architectures.

When selecting a photodiode, engineers must consider factors such as dark current, capacitance, rise time, and shunt resistance relative to their application’s optical power levels and bandwidth. Zealnew’s technical team assists customers in comparing these parameters across different photodiode families, ensuring the chosen component delivers the required signal-to-noise ratio. The company also stocks specialized avalanche photodiode modules with integrated amplifiers and temperature compensation for critical lidar and spectroscopy applications.
