The maximum surge current rating for the 84134021 is 100A for 1 cycle (16.7ms) according to Crydom's application notes.
Yes, the 84134021 can be used for DC loads, but it's essential to ensure the load voltage is within the specified range (up to 280VDC) and the load current is within the rated current (up to 40A).
Crydom recommends a minimum load current of 100mA to ensure reliable operation of the 84134021. Operating with lower load currents may lead to inconsistent performance.
To protect the 84134021, use a suitable overvoltage protection device (e.g., a transient voltage suppressor) and an overcurrent protection device (e.g., a fuse or circuit breaker) in the circuit design.
Crydom recommends a PCB layout that provides good thermal conductivity and heat dissipation. Use a heat sink or thermal pad to ensure the junction temperature remains within the specified range (up to 125°C).
