The 40 W peak pulse power and 3 A rating (8/20 µs waveform) cover the ESD strikes a typical interface sees in industrial or automotive environments, and the -40 to 125°C operating range keeps it working under the hood or on a factory floor. ## What the 5.5 V standoff and 6 V breakdown mean for your rail The 5.5 V max reverse standoff means this part will not conduct appreciable leakage on a nominal 5 V supply rail — it stays invisible until a transient pushes the line above 6 V (the minimum breakdown voltage). That 1 V window between standoff and breakdown is the trigger band: a 5 V USB or GPIO line sees no loading during normal operation, but an ESD event that drives the line past 6 V gets clamped to a typical 13 V. For 3.3 V logic the margin is even wider, so the part works there too, though the 5.5 V standoff is the headline fit. ## Reworking the 4-X2SON — what to expect under the hot air The 4-X2SON (0.8x0.8 mm) is a tiny leadless package with an exposed pad underneath. The pad layout is a single row of four lands; the exposed pad is the main thermal and electrical connection for the Zener junctions. Preheat the board to 125°C, use a fine nozzle, and keep the airflow low to avoid blowing the part off the pads. It reflows clean with a 260°C peak profile, but the small mass means it reaches temperature fast — watch the solder paste wetting and pull the heat as soon as the joint fillets form. Will it survive the hot air? Yes, but only if you have the orientation marked and the pad stencil aperture matched to the 0.8 mm body.","metaTitle":"TI TPD4E101DPWR Zener ESD Protection, 4-Ch, 5.5V","metaDescription":"Texas Instruments TPD4E101DPWR: 4-channel Zener ESD protection, 5.5V reverse standoff, 40W peak pulse, 3A (8/20µs), -40 to 125°C, 4-X2SON (0.8x0.8mm).

With a 5.5 V max reverse standoff and 6 V minimum breakdown voltage, it is designed to protect 5 V signal lines. The 3 A peak pulse current (8/20 µs) and 40 W peak pulse power cover the ESD energy levels specified in IEC 61000-4-2 for contact and air discharge."},{"question":"What is the capacitance of TPD4E101DPWR?","answer":"The evidence does not list a capacitance value for this part. For high-speed interfaces like USB 2.0 (480 Mbps), low capacitance is critical to avoid signal degradation. Without a confirmed capacitance figure, verify the datasheet directly or test a sample on your target trace before committing the BOM."},{"question":"Is TPD4E101DPWR bidirectional?","answer":"Yes, all four channels are bidirectional, meaning each channel can clamp a positive or negative transient with respect to ground. This makes it suitable for differential signal pairs (like USB D+/D- or RS-485 A/B) where the signal swings both above and below the reference."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPD4E101DPWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPD4E101DPWR when reusing this data.
