Frequently Asked Questions
What clip types are compatible with the SRQ-XJ-01 clip-mount base?
The SRQ-XJ-01 base is designed to accept standard push-on spring clips sized for TO-220 and similar packages. Clip compatibility depends on the specific clip manufacturer's tab width and spring force rating. CZT can advise on recommended clip part numbers for production assembly applications.
Is the SRQ-XJ-01 suitable for use inside sealed enclosures?
Yes, the SRQ-XJ-01 can be used in sealed enclosures relying on natural convection and conduction. However, thermal resistance will be higher than in open-air installations. For sealed enclosures, calculate worst-case ambient temperature rise and verify that junction temperatures remain within device ratings under maximum load.
Can the SRQ-XJ-01 be used without thermal interface material when clip-mounted?
It is not recommended. Even with clip mounting, surface irregularities between the device tab and heatsink base create air gaps that significantly increase contact resistance. A thin layer of thermal grease or a pre-applied phase-change pad ensures consistent, low-resistance thermal contact across the interface.
