The 1N4702 (DO35) is a single zener diode, which is designed of two terminal chip and made of Silicon, it’s maximum power dissipation (PD) can reach up to 500mW. With an excellent avalanche characteristic and tight limits on maximum reverse voltage, the 1N4702 (DO35) is the perfect choice for industrial and engineering applications.
If reverse the polarity, the 1N4702 (DO35) can be used as a switch. When the reverse voltage is below the breakdown voltage, the 1N4702 (DO35) behaves like an open circuit and tends to block any current flow, hence protecting circuits. But when the reverse voltage applied to it is above the zener breakdown voltage, the diode turns on and becomes very conductive, allowing the current to flow through it.
The main application field of 1N4702 (DO35) is to provide a stable voltage reference and offer the overvoltage protection. On the one hand, it use the Zener effect to provide a stable voltage, which then can be used for battery-operated systems and attenuators. On the other hand, the 1N4702 (DO35) can be used as a self-protected switching circuit, which can limit the voltage surge and drops. Thus, it is also an ideal choice for over-voltage protection for applications such as automobiles, home appliances, and consumer electronics.
The working principle of 1N4702 (DO35) can be summarized as follows. When the diode operates in the forward direction, the depletion region width increases with increasing forward bias until the threshold voltage is reached, allowing current to flow. But when a reverse voltage is applied, the diode will be in reverse biased, and the depletion width increases up to a point where the cross over point is reached; this causes a rapid increase in current, and resulting in electron jumps across the barrier and leading to a Zener breakdown.
In conclusion, 1N4702 (DO35) is a single Zener diode that offers the features of excellent avalanche gradient, large maximum power dissipation, and tight reverse voltage limits, which make it the perfect choice of protecting application in industrial and engineering applications. The 1N4702 (DO35) leverages the Zener effect to provide a stable voltage reference, limit voltage surge and drop, and act as a switch.
