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
