CRM25TD07R1 CR Micro 250V 7A IPM QFN 7x7

The CR Micro CRM25TD07R1 is a 250 V 7 A intelligent power module in a QFN 7x7 package, wired as a half-bridge using MOSFET power stages. Protection on board covers under-voltage lockout. Designed for Hair dryer and Pumps.

Key Specifications

Same-Rating Selection Table

2 part numbers share the same 250 / half-bridge rating — sorted by current.

Applications

Hair dryer and Pumps — the module's rating and package are sized for this class of load.

Selection Notes

• The module integrates gate drive and protection. The input side expects logic-level PWM, not a raw gate signal — do not add an external driver.
• Fault output is open-drain on most of these modules. Fit a pull-up and latch it in the controller, otherwise the module restarts into a fault.
• Check the dead time and minimum pulse width in the datasheet. The internal interlock is a protection layer, not a substitute for correct timing.
• Thermal design dominates reliability. Use the module's internal thermistor or the case-to-heatsink path to size the heatsink for the actual switching loss.

Common Questions

What topology does the CRM25TD07R1 implement?

It is a half-bridge module rated 250 V / 7 A.

What protection is built into the CRM25TD07R1?

The module integrates under-voltage lockout. External fault handling still has to latch the fault signal and sequence a safe restart.

What applications is the CRM25TD07R1 intended for?

Hair dryer and Pumps — a match for the module's power rating and package thermal path.

What package does the CRM25TD07R1 come in?

QFN 7x7. Check the datasheet mechanical drawing for lead spacing and thermal pad dimensions before laying out the footprint.

How do I choose between the 2 part numbers in this rating group?

All 2 share the same voltage and package class. Sort by on-resistance first, then check gate charge: the lowest Rds(on) part is not automatically the best choice if the stage switches at high frequency. The table above lists them in ascending Rds(on) order.
