NSD914F3T5G Discrete Semiconductor Products

NSD914F3T5G is one of the most commonly used single rectifier diodes in the field with a maximum average forward current of 1A. It is primarily used as rectifier and switching control. Since its construction is a diode consisting of a PN junction and also contains a cathode and an anode region, it carries out conduction of electric current in one direction only. This characteristic makes it suitable for applications such as in power supply and rectification of AC to DC, switching physical loads between logic power supply, DC-DC converters, voltage protection and polarity protection etc.

It has a peak reverse voltage of 900V and a maximum forward voltage of 1.15V. Its maximum do-35 glass case has a case temperature range from is from -55°C to +150°C.

NSD914F3T5G works on the principle of a rectifier diode i.e. it allows the current to flow in only one direction while restricts the current flow in the reverse direction. This is possible due to the different conductance characteristics of anode and cathode region when the applied voltage is reverse biased and forward biased. When it is reverse biased, both anode and cathode get open and there is no current flow. Similarly, when it is forward biased, the p-type gets open, thereby allowing the electric current to travel from the anode to the cathode.

Typically, single rectifier diodes which includes NSD914F3T5G are used anywhere where AC current needs to be rectified or when there is need for controlling the current flow, for example, for switching control. This particular diode is mostly used in applications such as voltage stabilizers, charging systems, lightning protection, power supply, electronic circuit boards, LED power supply and many other electronic applications.

The construction of the NSD914F3T5G consists of a Pn junction between the anode and cathode, along with an insulator between them to prevent its short-circuiting. The cathode consists of an indicator as its distinguishing factor, which is a line pattern. This helps in distinguishing the topology of the diode’s wiring and it also helps in its easy fitment in circuit boards.

It incorporates Shockley’s diode equation to determine its forward and reverse current condition. This diode is mainly used as a rectifier, but due to its high forward voltage, it can also be used in other applications such as voltage protection, regulating flow of current in AC to DC circuits and for switching operations. Its operating temperature range is also fairly good.

As in other diodes, NSD914F3T5G diode has maximum Reverse Voltage (VR) rating to make sure that during the reverse biased condition, its breakdown voltage does not exceed its VR rating. This diode also has a PIV rating, which is the Peak Inverse Voltage. Similarly, the maximum average forward current or otherwise called the IF (AV) rating is given for specifying the current limit of this diode to make sure its die temperature does not exceed its maximum permissible temperature.

To conclude, as a single rectifier, NSD914F3T5G can be used as a regulator and solid-state controller in many AC-DC, DC-DC circuits, it can also be used to limit the current in LED power supply, voltage protection circuit and many other applications.
