Product details
Overview
D26V0H1U2LP20-7 from Diodes Incorporated is a unidirectional transient voltage suppression (TVS) diode designed for ESD protection of high-speed data lines in portable electronics. It features a 26 V reverse standoff voltage, 28 V minimum breakdown voltage, 40 V clamping voltage at 9.5 A peak pulse current, and 630 pF channel input capacitance - enabling robust ±30 kV IEC 61000-4-2 contact/air discharge protection in space-constrained USB, audio, and camera interfaces.
For engineers reviewing the D26V0H1U2LP20-7 datasheet, D26V0H1U2LP20-7 pinout, D26V0H1U2LP20-7 application, or D26V0H1U2LP20-7 equivalent, key selection criteria include its U-DFN2020-2 package footprint (2.05 × 2.05 mm), low 100 nA leakage at 26 V, 300 W peak pulse power rating, and suitability for high-density PCB layouts requiring sub-1 mm profile and minimal parasitic capacitance.
Technical Context
This TVS diode operates as a unidirectional clamp between signal line and ground, triggering conduction when reverse voltage exceeds 28 V to divert ESD transients away from sensitive IC inputs. Its silicon avalanche structure ensures repeatable breakdown with tight VBR tolerance (28–31.9 V) and stable clamping performance under 10/1000 µs surge waveforms.
The device integrates into high-speed analog/digital interfaces where low capacitance (630 pF @ 0 V) and fast response (<1 ns) are critical to preserve signal integrity. Its thermal resistance (RθJA = 250 °C/W) and 500 mW steady-state power dissipation support reliable operation on standard FR-4 PCBs with Diodes' AP02001 pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 26 V - Maximum continuous DC voltage before significant leakage; sets operating margin below breakdown. |
| Breakdown Voltage (VBR) | 28–31.9 V @ 1 mA - Confirmed avalanche onset range; defines minimum trigger threshold for ESD clamping. |
| Clamping Voltage (VCL) | 40 V @ 9.5 A, 10/1000 µs - Peak voltage seen by protected circuit during worst-case surge; limits stress on downstream ICs. |
| Peak Pulse Power (PPP) | 300 W - Sustained energy-handling capability per IEC 61000-4-2 waveform; enables single-device protection for common ESD events. |
| Channel Input Capacitance (CT) | 630 pF @ 0 V, 1 MHz - Low enough to avoid signal degradation in USB 2.0 and audio paths; verified at zero bias. |
| ESD Rating | ±30 kV air & contact per IEC 61000-4-2 - Full compliance with highest industrial ESD immunity level for handheld devices. |
| Leakage Current (IRM) | 100 nA @ 26 V - Minimal DC loading on signal lines; preserves battery life and logic thresholds in always-on interfaces. |
Pinout & Package
Package: U-DFN2020-2 (2.05 × 2.05 × 0.605 mm), lead-free, halogen-free, RoHS-compliant surface-mount package with NiPdAu-plated copper terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to protected signal line; conducts transient current toward ground when reverse-biased beyond VBR. |
| Pin 2 | Cathode | Connected to system ground; provides low-impedance return path for ESD current during clamping event. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 0.605 mm max height - Enables placement under connectors and beneath thin bezels in smartphones and wearables. |
| IEC 61000-4-2 certified ESD protection | ±30 kV contact/air - Eliminates need for external ESD test validation in end-product certification. |
| Single-channel configuration | One bidirectional-capable diode in compact 2-pin layout - Simplifies routing and reduces BOM count vs. dual-diode arrays. |
| Low channel input capacitance | 630 pF - Maintains signal rise/fall times in USB 2.0 (480 Mbps) and stereo audio differential pairs without distortion. |
Applications
| USB 2.0 Data Lines | Smartphone Camera Interfaces |
|---|---|

Use Value: Extends field reliability by preventing interface IC failure without adding series impedance or signal delay. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ26A | DO-214AC package (4.5 × 2.7 mm), 400 W PPP, 500 pF CT, higher leakage (1 µA) | Requires larger PCB area; better for higher-power surges but unsuitable for ultra-thin portable designs | Select when board space allows and >300 W surge margin is needed; not pin-compatible |
| SP1001-02UTG | SOD-323 package (2.7 × 1.7 mm), 350 W PPP, 300 pF CT, 24 V VRWM | Lower clamping (33 V) and capacitance ideal for high-speed HDMI, but reduced voltage margin for 26 V rails | Prefer for bandwidth-critical links needing <350 pF; verify VRWM compatibility with 26 V system rail |
Compared with SMAJ26A and SP1001-02UTG, D26V0H1U2LP20-7 uniquely balances ultra-small footprint (2.05 × 2.05 mm), 26 V standoff, and 630 pF capacitance - making it optimal for space-constrained 26 V interface protection where moderate bandwidth suffices and strict height limits apply.

FAQ
What is the maximum operating temperature for D26V0H1U2LP20-7?
The device supports continuous operation from –65 °C to +150 °C ambient temperature. Its thermal resistance (RθJA = 250 °C/W) is specified for FR-4 PCBs using Diodes' AP02001 pad layout; derating begins above +70 °C per Figure 2 in DS36767 Rev. 2–2.
Does D26V0H1U2LP20-7 meet automotive AEC-Q200 requirements?
No - D26V0H1U2LP20-7 is not AEC-Q200 qualified. It is rated for commercial/industrial use only. For automotive applications, Diodes offers the AEC-Q200-qualified D26V0L1U2LP20 variant with identical electrical specs but extended qualification testing.
Can D26V0H1U2LP20-7 be used for bidirectional signal protection?
No - it is strictly unidirectional. Pin 1 (anode) must connect to the signal line and Pin 2 (cathode) to ground. For bidirectional protection of AC-coupled lines like USB or HDMI, a dual-diode array such as D3V3M1U2LP20 is required.
What is the recommended PCB pad layout for D26V0H1U2LP20-7?
Use Diodes' AP02001 pad layout (document AP02001.pdf), featuring 0.55 mm wide × 1.9 mm long solder pads with 1.35 mm center-to-center spacing and thermal relief traces. This layout ensures optimal thermal dissipation and solder joint reliability per J-STD-020 moisture sensitivity Level 1.
