Why is a diode used with inductive loads?
This can happen in resistive as well as inductive loads, but inductive loads generate a higher voltage and this causes increased arcing. Increased arcing decreases switch life. Direct current (DC) inductive circuits typically use a diode to prevent the high voltage.
Are LED lights an inductive load?
3 Answers. LEDs are a nonlinear load and probably these lamps will not have a power factor correction converter. This means that the current will not be sinusoidal therefore you will have some reactive power flowing. There may be a PFC choke before the rectifier bridge.
Which is self protected MOSFET from Diodes Incorporated?
To help cope further with transients, self-protected MOSFETs, such as the ZXMS6004FFQ from Diodes Incorporated, utilize a fully protected topology that incorporates over-temperature and over-current protection circuits. As can be seen in the block diagram in figure 3, this is in addition to an over-voltage and ESD input protection.
Why do we need ESD protection on MOSFETs?
It features ESD protection on the input and active-drain clamping across the output. The latter is particularly useful when switching relays because, due to their inductive nature, large transients can be created when deactivating the relay and these transients have the potential to destroy unprotected MOSFETS.
How to protect MOSFETs in a circuit Circuit?
The above mentioned points regarding correct implementation of mosfets can be easily included in any circuit in order to safeguard mosfets from mysterious malfunctions and burning. Even in complicated applications such half-bridge or full bridge mosfet driver circuits along with some additional recommended protections.
How does diodes zxms6004ffq self protected MOSFET work?
The self-protection features of Diodes’ ZXMS6004FFQ MOSFET. This self-protected MOSFET uses a temperature sensor and thermal shutdown circuit to protect against over-temperature. This circuit is active when the MOSFET is on and is triggered once a threshold temperature, typically 175°C, is exceeded.
