SE07PD-E3/85A application field and working principle

A SE07PD-E3/85A diode is a type of single rectifier. It is a non-isolated and package semiconductor diode constructed from a 1.35V Zener semiconductor material, which is used to forward current and provide protection from the reversed voltage.

Application field

The SE07PD-E3/85A is applied in many different circuits ranging from power supply and lighting to displays, imaging and industrial equipment. Generally, the common application fields include:

1. Lighting and LED Products
2. Automotive
3. Printers
4. Checkout Lanes
5. Chargers
6. Imaging
7. Industries
8. Heating and air conditioning

Working Principle

The SE07PD-E3/85A diode uses semiconductor material as an avalanche diode, which works by allowing current to flow in one direction when voltage is applied, and blocks current from flowing in the reverse direction. It allows current to flow by creating a low-resistance channel for current when the voltage is applied to its anode side, and the low-resistance channel is absent when the voltage is applied to its cathode side.

When the diode is connected in Device Under Test (DUT), it disables the diode and behaves like an open switch. Proper connection and polarity of the diode is essential in order to ensure accurate testing of the DUT. And since the SE07PD-E3/85A is a single rectifying diode, it can only rectify with one direction, either in forward or reverse direction.

The reverse voltage breakdown of the diode is 1.35V. This breakdown voltage is quite low, available in the application of automotive troubleshooting, battery protection and warning lights. As well, its low-resistance and low-capacity makes it ideal for kinds of applications.

Conclusion

The SE07PD-E3/85A single rectifying diode plays an important role in many different circuits or applications, ranging from lighting and LED products to industrial equipment or imaging. Its low-resistance and low-capacity makes it ideal for automotive use, as well as battery protection and warning lights. Moreover, the breakdown voltage is quite low, making it suitable for application in low-voltage areas.
