The AS4PJHM3/86A diode is a single rectifier diode rated for a peak reverse voltage of 600V and a continuous forward current of 2 A. Its construction is based on an improved planar process using oxide passivation and the latest metallurgical metal diffusion contact technology. This gives the diode an ultra-low forward voltage drop (VF) – down to 0.55V at 2A – and a very fast reverse recovery time (trr) of 50ns.

In the area of General Purpose Diodes, the AS4PJHM3/86A is considered to be a highly efficient and reliable rectifier diode, suitable for a broad range of applications. This includes the use as a full-wave bridge rectifier to convert AC to DC, battery charging, motor control, transformer switching and light triggering, amongst others.

At the heart of the diode lies its working principle, which is based on the basic action of an electrolytic diode. When current is applied to a diode, electrons will flow through the device, creating an electric field. This electric field establishes a potential barrier, known as the junction voltage. When voltage is applied to a diode in the reverse direction, it will not allow electrons to flow but will instead block the electron flow and prevent further current from passing. This phenomenon is known as reverse current blocking, and the amount of blocking is known as the reverse breakdown voltage.

In order to facilitate the breakdown voltage of a diode, the AS4PJHM3/86A has a built-in avalanche junction with a soft recovery. This avalanche junction will break down the electric field of the diode at a given point and allow a controlled amount of current to flow when the given reverse voltage is reached.

In addition to its use as a rectifier, the AS4PJHM3/86A can also be used to make ultra-fast switching in applications where speed is a priority. Due to its ultra-low forward voltage drop (VF) and high current ratings, the diode can be used to make fast-switching in a variety of simple to complex applications. The diode can also be used to protect circuits from unwanted voltage transients by clamping the voltage in excess of a given point.

In summary, the AS4PJHM3/86A is a highly efficient and reliable single rectifier diode rated for a peak reverse voltage of 600V and a continuous forward current of 2A. Its ultra low VF and fast reverse recovery make it an ideal selection for a broad range of general purpose rectifying applications where speed is a priority. The diode can also be used to protect circuits from unwanted voltage transients.
