Safe Operating Area Coffee Mug – Human Caffeination SOA Engineering Humor

Start your day like a true engineer—with a full Safe Operating Area analysis.
This mug parodies a MOSFET SOA curve by mapping it to the only thing that really determines human performance: coffee temperature and caffeine dose.
From “Cognitive V_TH limitation” to “Sarcastic region” to the dreaded “Unstable output,” every label captures the emotional and behavioral transfer function of a coffee-powered human. The “Hot coffee limitation region” even includes a realistic-sounding derating note based on typical tongue failure point—because of course it does.
Perfect for electrical engineers, semiconductor folks, PCB designers, power geeks, lab rats, caffeine addicts, and anyone who appreciates a well-labeled behavioral instability zone.
