5V rail ESD clamp in a 0402 footprint
The TPD6V8LP-7 is a single-channel unidirectional Zener TVS diode from Diodes Incorporated, designed to protect a 5V signal or power rail from ESD and low-energy transients.
85W peak pulse — what it handles and what it doesn't
The datasheet explicitly notes no power line protection, so it belongs on signal or low-power DC rails, not on mains or bus-powered inputs. Capacitance measures 65pF at 1MHz, low enough for most data lines up to a few MHz without degrading signal integrity. For high-speed interfaces (USB 2.0, Ethernet, HDMI), a sub-1pF TVS would be needed; this part suits GPIO, keypad, I2C, or general-purpose 5V rail protection. Operating temperature spans -65°C to 150°C junction, covering automotive under-hood and industrial environments. The X1-DFN1006-2 package is a 0402-sized leadless package — 1.0mm x 0.6mm with two terminals — suitable for high-density PCB layouts where space is tight.
Diodes Incorporated lists the TPD6V8LP-7 as Last Buy. This is the final production window — once current stock and last-time-buy inventory are consumed, the part will be discontinued. No official successor order code is recorded in the lifecycle entry. For existing designs, procure sufficient lifetime buy quantities now; for new designs, evaluate an alternative single-channel 5V TVS in the same 0402 footprint.
