DP83849ID: ESD Protection Recommendation for POE Application

Part Number: DP83849ID
Other Parts Discussed in Thread: STRIKE

My customer is using DP83849IDVS in a POE application and they are experiencing ESD failure with the device. The design already includes TVS diodes (12KV/15KV) on the TPTDP_A, TPTDM_A, TPRDP_A, TPRDM_A, TPTDP_B, TPTDM_B, TPRDP_B, and TPRDM_B pins. What other protection recommendations do you have for this application?
