A187B is a single-phase, full wave, high-precision and low-power rectifier diode, which is mainly used for precision rectification and circuit protection. It can be used to accurately rectify AC power from small to large amplitudes and protect internal circuit elements from an excessive current flowing through them. The device is integrated with highly efficient reverse current blocking capabilities, preventing any current from flowing in the opposite direction.A187B provides a constant voltage to the circuit, allowing constructions and DIY projects to achieve accurate and repeatable results. It is designed to be suitable for use in most environments, including exposed conditions. Additionally, the device can also conduct bi-directional current as well as provide reverse protection in both positive and negative load conditions.In terms of its working principle, A187B has a construction that consists of two forward temperature-sensitive PN junction diodes in series. When there is no forward voltage, the diode is off, the current is blocked and no voltage is fed. When the applied voltage exceeds the current forward voltage, the diode will become active and the current will flow through it.When a voltage is applied in the forward direction, the diode has the highest possible breakdown voltage, meaning it can pass even high-power AC signals. The A187B is also engineered to pass reverse current at a low voltage, ensuring that the voltage stays within a safe range. This ensures maximum power dissipation, allowing the device to handle higher AC load currents than conventional rectifiers.Overall, while the A187B diode is designed primarily as a single-phase, full wave rectifying device, it can also be used for circuit protection as well. Its low reverse power dissipation and high temperature stable performance makes it a great choice for any project or construction requiring an accurate and repeatable rectification. Therefore, the A187B can be an effective and reliable option when it comes to rectifying AC power.
