Зачем подключать диод к магнитному замку

This doesn't mean you need to rush out and install diodes on all your locks. Many circuits include circuits to suppress such pulses. However, if you're experiencing frequent breakdowns in the controller's power transistor, especially when it's installed on a gate where the negative terminal of the reader is grounded to the structure, this is most likely the cause. The OLEVS 8:03 magnet turned out to be completely sealed, and the coil broke because the capacitor was ringing. It's beyond repair and in the trash.
