diode D1 blocks the current flow through the set-coil and diode D2 energizes the reset-coil. The latched relay in Figure 1 has two independent coil connections using 4 pins. Some dual-coil relays, ...

If you desire to drive a larger relay or want less base current, a Darlington driver (Fig 4) is recommended ... The clamp, free-wheeling or commutation diode provides a path for the inductive ...

This will cause the relay to reset. Figure 9. Dual coil latch relay with common connection uses 4 diodes for testing. Typical diode voltage drop is ~0.7V (for silicon diode). So the driver voltage ...

The four-layer diode was the key to William Shockley's plan to revolutionize AT&T's phone system. It was a great device in theory, but not in practice -- at least not at the time when Shockley ...

The new device delivers a 600 V load voltage and a 3750 VRMS isolation voltage within a compact SOP-4 ... relay’s optically isolated design combines an infrared emitter with a photovoltaic diode ...

The control pin is pulled to ground to keep the relay off. A diode is placed across the relay coil to manage the power flow when it discharges. An indicator LED is included to show when the relay ...

a pioneering solid-state relay with AEC-Q102 qualification and a 100 V load voltage. This innovative device is housed in a compact SOP-4 package and boasts rapid turn-on and turn-off times of 0.1 ...

Circuit symbol: the diode symbol consists of a triangle pointing ... This circuit uses a relay to control a 24V lamp using a lower 5V control circuit. When the PTM (push to make) switch is pressed ...
