A 2M170ZHR0G diode is a single Zener diode device type used in a wide array of applications. The 2M170ZHR0G is a Zener diode that is designed for operation at voltages between 18-75V with a maximum working current of 30mA and a maximum power dissipation of 0.5 Watts. The 2M170ZHR0G diodes have low leakage currents and low Zener impedance and can be used in voltage regulation circuits or as voltage switches in relay drivers.

Regulator Operation

The 2M170ZHR0G diode can be used in voltage regulation circuits to maintain a defined voltage level. This type of circuit is known as a Zener Regulator, and this type of diode is commonly known as a Zener diode because of the characteristics of its reverse breakdown voltage. When the voltage at the anode of the diode rises to the Zener voltage, it begins to conduct current in the reverse direction and so the voltage at the anode remains clamped at the Zener voltage and cannot rise beyond it. This is the principle behind voltage regulation with a Zener and the 2M170ZHR0G Zener diode can be used for this purpose. It is possible to use multiple 2M170ZHR0G diodes in parallel, to increase the current handling capability of the voltage regulator.

Relay Drivers

A 2M170ZHR0G diode can be used in a circuit to drive a relay. A relay is an electrical switch that is operated by an electromagnet and can be used to control a variety of electrical devices. In order to operate the relay when a certain voltage is present, the 2M170ZHR0G diode can be used to sense the voltage and, when the voltage reaches the breakdown voltage of the diode, it will begin to conduct current and the relay will be engaged. The diode therefore acts as a voltage switch, powering the relay when the voltage reaches the threshold level.

Availability

The 2M170ZHR0G Zener diode is available in a range of packages, from DO-201AD through to SOT-323 and it is usually available from major electronics distributors.

Limitations

The 2M170ZHR0G diode has some limitations that need to be taken into consideration when designing circuits with it. The maximum power dissipation is limited to 0.5 Watts, and the maximum working current is limited to 30mA, so the maximum load current must be taken into account when designing a voltage regulation circuit with this diode.

Conclusion

The 2M170ZHR0G diode is a versatile device that can be used in a wide range of applications. It can be used as a voltage regulator in order to maintain a steady output voltage, or as a voltage switch to control a relay. The device is available in a range of packages, and the maximum power dissipation and maximum working current should be taken into account when designing a circuit with the 2M170ZHR0G diode.
