These modules are designed to simplify inverter design by combining power switching elements with control logic. The DIP packaging facilitates through-hole mounting, suitable for various consumer electronics and industrial motor drive applications.

Replacement Considerations

Consult official manufacturer substitution guides for verified equivalents. Do not assume compatibility with other IPM models without verifying pinout, electrical ratings, and thermal characteristics against the PS21244-EP specifications.

FAQ

What is the maximum junction temperature for the PS21244-EP?

The maximum junction temperature rating is 150°C. However, for safe operation, the average junction temperature should be limited to 125°C when the case temperature is at or below 100°C.

Does the PS21244-EP support short-circuit protection?

Yes, it includes self-protection capabilities with a short-circuit protection supply voltage limit of 400 Volts. This protection functions specifically for the low-arms.

What is the isolation voltage between the connection pins and the heatsink plate?

The AC isolation voltage is 2500 Volts for 1 minute at 60Hz sinusoidal frequency.
