Notes
1. Short-term is understood as the definition stated in Telcordia Generic Requirements GR-63-Core
2. ΘJA , the total junction to ambient thermal resistance as measured according to JEDEC Standard
JESD51 (2S2P)
3. ΘJB, the junction-to-board thermal resistance and ΘJT, the residual junction to ambient thermal
resistance are obtained by simulating conditions described in JEDEC Standard, JESD 15-8
