Thermal model

raghava235

Hai,

Greetings.

We are developing a dc circuit breaker design for which we require high efficiency. We are planning to use cpm3-1200-13A devices. However, the datasheet has not provided the die sizes. Also, we require the dynamic thermal performance of the die at high currents for a short time. To say specifically, When a fault occurs, the current ramps in the die and then we will sense the current and turn it off. So how much of a ramp current can the die bear, and what is the temperature rise in the die? If you have any reference data on the temperature rise based on any layouting. I request you to please provide. Thank you. The dies are really making our design compact. So we are looking forward to using them. Please provide the required details. If any cauer model is developed from experiment results please share. Here I am attaching few images of the desired thermal model we are expecting. THank you
