To help you complete your piece, could you provide any of the following? Disclaimer: This report is a synthesis based on
High-efficiency driving for LED lighting systems.
If you’re certain of the marking and need a reasoned analysis for a write-up, I can provide a based on common interpretations:
Recommendation: For new designs, engineers should evaluate if a lower $R_DS(on)$ device can improve efficiency. However, for repair of legacy equipment or cost-sensitive, low-frequency applications, the 2A155D remains a viable choice.
