1N4687 Datasheet/PDF1N4687 - Applications and Working Principle
1N4687 is a popular zener diode with a variety of applications, including protection circuits, voltage regulation and rectification. It is also used in circuit designs requiring a low forward-voltage drop and low leakage current. The 1N4687 diode is an ideal choice for low-voltage power supplies, since it ensures reliable voltage regulation with minimal additional cost.
Structure and Ratings of 1N4687
1N4687 is a single zener diode with its anode connected to the cathode. It has a relatively high-sustaining voltage and a low forward-voltage drop. It is rated for use at voltages from 6.2 to 100 V, with a steady-state current of 15 mA. At higher voltages, the maximum rating for the device decreases. The diode can withstand temperatures up to 150 °C.
Working Principle of 1N4687
The basic principle of zener operation is the same for all versions. A zener diode is an electronic component that helps regulate electrical current by allowing current to pass through it only one way. If the reverse voltage across the diode exceeds its breakdown voltage (Vz), then the device breaks down and current passes through it, preventing the voltage from rising further. This breakdown voltage is precisely controlled for each diode to ensure precise voltage regulation.
