Models with built-in diodes

The diode absorbs surge from the coil. This type is best suited for applications with semiconductor circuits.

With Diode

Without Diode

Note: 1. Make sure that the polarity is correct.

2. The release time will increase, but the 20-ms specification for standard models is satisfied.

3. Diode properties:The diode has a reversed dielectric strength of 1,000 V.

Forward current: 1 A
