技术问答

A Photodiode is a semiconductor device that can convert light energy into electrical energy. It works based on the principle of photoelectric effect, where light is absorbed by the photodiode and excites electron-hole pairs, generating current. Photodiodes have a wide range of applications in light detection and signal measurement. Today we will introduce SLKOR's photodiode SL9302.

The SL9302 is a silicon PIN photodiode that utilizes silicon material for its fabrication. The PIN structure refers to the addition of a lightly doped internal region on both sides of the PN junction, forming a P-type internal-N-type junction. This structure allows the SL9302 to have a wider response frequency range and higher responsiveness. Additionally, silicon material has features such as good stability and low price, making it a commonly used photodiode.

The SL9302 is an excellent performing silicon PIN photodiode. Its planar front-illuminated structure allows light to be received and converted into electrical signals more efficiently. Compared to other photodiodes, it has higher responsiveness, meaning it can detect changes in light signals more sensitively. It also features low dark current and high reliability, allowing it to operate stably for long periods.

The SL9302 has many excellent performance parameters: VR(V): 40V, ID(nA): 0.1nA, Topr(℃): -40~100℃, λ(nm): 400~1100nm, Package: 1206. Firstly, its maximum operating voltage is 40V, so care should be taken to not exceed this voltage when in use. Secondly, the dark current of the SL9302 is 0.1nA, which means measures need to be taken to reduce noise to ensure accurate signal detection. Additionally, the working temperature range of the SL9302 is -40~100℃, so caution should be exercised when using it in high or low-temperature environments. Lastly, the response wavelength range of the SL9302 is 400~1100nm, so appropriate light sources need to be selected for different applications.

The spectral response range of the SL9302 is very wide, and it can effectively receive and detect light signals ranging from visible light to near-infrared. Its peak response wavelength is 930nm, allowing it to perform excellently in many applications. For example, fiber optic communication can be used to receive and detect light signals for high-speed, stable data transmission. In sensing and ranging applications, its high responsiveness and wide spectral response range can be used to accurately measure and detect the position, distance, and features of target objects. Additionally, the SL9302 is suitable for various industrial control systems. It can be used for fast light pulse detection to help achieve high-speed data acquisition and processing. Its high reliability and stability make the SL9302 ideal for use in harsh working environments, such as industrial control systems under high or low-temperature conditions.

In summary, the SL9302 photodiode is a silicon PIN structure photodiode with a wide range of applications and excellent performance. It can convert light signals into electrical signals and is suitable for fields such as communication technology, optical measurement, image sensing, and optoelectronic conversion. The SL9302's high responsiveness, low dark current, wide wavelength range, and fast response speed make it an ideal choice for a photodiode. However, when using it, attention should be paid to how its parameters affect its application to ensure its normal operation.

Photodiode SLKOR SL9305 with Reverse Voltage (VR) of 40V and Dark Current (ID) of 0.1nA

The SL9305 is designed with a planar positive-intrinsic-negative (PIN) structure, which allows for high photovoltaic conversion efficiency and sensitivity. This structure also helps to reduce leakage and reflection on the photosensitive surface, improving the signal detection sensitivity. With a dark current of only 0.1nA, it maintains a low current level even in the absence of external light. This feature enhances the signal-to-noise ratio and ensures accurate detection of light signals.
