SJPE-H4VL

Diodes - Rectifiers - Single

The SJPE-H4VL is a single diode rectifier that offers advantages in low voltage applications. It is a low voltage diode with a maximum reverse voltage of 600V, a forward voltage and forward current of 2.0V/0.5A respectively. It is built with a glass passivated chip which not only increases durability, but also has a high surge capability. The SJPE-H4VL can be used to transfer and rectify alternating currents (AC) at low voltages and are popularly used in ultra-sensitive circuits, automotive circuits, and other applications that require a low input and output voltage.

Application Areas

The SJPE-H4VL may be used in devices that require DC power such as digital cameras, camcorders, cell phones, notebook computers and other portable electronic devices. It is ideal for applications that need a relatively low current level, such as small digital appliances and portable devices, especially when the power supply must be scalable and the efficiency rate is of primary importance.

Additionally, the SJPE-H4VL is commonly used in the medical industry for respiratory machines, anesthesia machines, and other electrosurgical equipment. It can also be used in the industrial sector for welding machines, magnetics control, motor control, and computer control systems.

Working Principle

The SJPE-H4VL works by acting as a rectifier, meaning it can convert AC power into DC power. The device is constructed with a central cathode surrounded by an anode, which ensures that the current flows in one direction only. The device is built with a glass passivated chip that increases its durability and surge capability.

When the voltage applied to the SJPE-H4VL is lower than the reverse breakdown voltage (Vbr), the diode will be in the off-state and no current can flow through it. When the central cathode is positively charged, current will begin to flow from the anode to the cathode as the diode switches from the off-state to the on-state.

Once it is in the on-state, the diode will remain in the on-state until the voltage reaches the reverse breakdown voltage again. This process allows the SJPE-H4VL to transform an AC input voltage into a DC voltage by rectifying the AC voltage waveform.

Conclusion

The SJPE-H4VL is a single diode rectifier designed for low voltage applications. It is built with a glass passivated chip that increases its durability and surge capability, making it ideal for ultra-sensitive circuits and automotive circuits. The device is commonly used in medical and industrial applications that require DC power, and it works by converting AC power into DC power through rectification.
