Figure 1 — Specified thermal operating area
1. The BCM in a VIA Package is cooled through bottom case (bottom housing).
2. The thermal rating of the BCM in a VIA Package is based on typical measured device efficiency.
3. The case temperature in the graph is the measured temperature of the bottom housing, such that operating internal junction temperature of the
BCM in a VIA Package does not exceed 125°C.
