Product details
Overview
D24V0H1U2LP-7B from Diodes Incorporated is a unidirectional transient voltage suppression (TVS) diode designed for ESD protection of signal lines in portable electronics. It features a 24 V reverse working voltage (VRWM), ±30 kV IEC 61000-4-2 contact/air ESD rating, 47 pF typical junction capacitance, and 9 A peak pulse current (8/20 µs), making it suitable for high-speed USB, HDMI, and audio interface protection in smartphones and digital cameras.
For engineers reviewing the D24V0H1U2LP-7B datasheet, D24V0H1U2LP-7B pinout, D24V0H1U2LP-7B application, or D24V0H1U2LP-7B equivalent, key selection criteria include clamping voltage at 1A/9A, low-profile DFN package compatibility with fine-pitch PCB layouts, thermal derating behavior above 25°C, and compliance with IEC 61000-4-2 Level 4 ESD immunity requirements.
Technical Context
This TVS diode operates as a unidirectional clamp between cathode and anode, activating only when reverse voltage exceeds 25 V (VBR min). Its low 47 pF capacitance minimizes signal integrity impact on data lines up to 100 Mbps, while the 31 V clamping voltage at 9 A ensures robust surge suppression without overstressing downstream ICs.
The device uses a silicon avalanche structure optimized for fast response (<1 ns) to ESD transients and is rated for continuous power dissipation of 250 mW at 25°C, with thermal resistance (RθJA) of 500°C/W on standard FR-4 layout-critical for thermal management in compact handheld enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24.0 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA; sets upper limit for protected line voltage. |
| VBR (min) | 25 V - Breakdown initiates at ≥25 V (1 mA test), ensuring reliable turn-on above normal signal swing. |
| VCL @ 9A | 42 V - Clamped voltage during 8/20 µs surge; defines worst-case stress on downstream IC input pins. |
| CT | 47 pF - Junction capacitance at 0 V, 1 MHz; enables use on USB 2.0 and audio lines without signal attenuation. |
| IPP | 9 A - Peak pulse current handling per IEC 61000-4-5 (lightning), defining surge energy absorption capability. |
| ESD Rating | ±30 kV - Contact and air discharge per IEC 61000-4-2 Level 4; meets highest industrial/portable ESD immunity class. |
| RθJA | 500 °C/W - Thermal resistance to ambient on standard 2 oz copper pad; dictates maximum allowable power at elevated temperatures. |
Pinout & Package
Package: X1-DFN1006-2 - ultra-compact, 1.08 mm × 0.68 mm footprint, 0.53 mm max height, lead-free NiPdAu-plated terminals, JEDEC-compliant moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Signal Input / Protected Line | Anode connects to the line requiring ESD protection (e.g., USB D+, HDMI TMDS+); forward-biased during positive transients. |
| Pin 2 (Cathode) | GND Reference / Clamp Return | Cathode ties to system ground; provides low-inductance return path for surge current during reverse-biased clamping events. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 Compliance | ±30 kV contact/air discharge - eliminates need for external ESD test margining in consumer-grade designs. |
| Low Capacitance | 47 pF typical - preserves signal rise/fall times on high-speed interfaces without added termination or equalization. |
| Ultra-Small Footprint | 1.08 mm × 0.68 mm - fits within tight spacing constraints of modern smartphone flex circuits and camera modules. |
| RoHS & Halogen-Free | Lead-free, <900 ppm Br/Cl, <1000 ppm Sb - satisfies automotive and EU environmental compliance without performance trade-offs. |
| Thermal Derating Curve | 250 mW @ 25°C, linearly derated to zero at 150°C - enables accurate lifetime estimation under sustained ambient temperature stress. |
Applications
| Smartphone Front-Panel Interface | Digital Camera HDMI Output |
|---|---|
Use Scenario: Protecting touch-screen controller I²C lines and proximity sensor inputs from user-hand ESD events during daily handling. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed directly at connector entry point to shunt ESD current to GND before reaching MCU GPIOs. Use Value: Prevents latch-up or permanent gate oxide damage in 28 nm/40 nm process MCUs by limiting clamped voltage to ≤42 V during ±30 kV discharges. | Use Scenario: Shielding HDMI TMDS differential pairs from ESD induced by cable insertion/removal in compact camcorders. IC Role / Device Role / Timing Role: One-channel TVS per signal line (D0+/D0−, D1+/D1−, etc.), mounted adjacent to HDMI receptacle with minimal trace length. Use Value: Maintains signal integrity up to 1.65 Gbps by holding capacitance to 47 pF and preserving edge rate via sub-1 ns response time. |
| USB-C Audio Adapter | Industrial Handheld Scanner |
Use Scenario: Safeguarding analog audio paths (MIC_IN, HP_OUT) in USB-C dongles exposed to repeated plug/unplug cycles. IC Role / Device Role / Timing Role: Low-capacitance unidirectional clamp on each analog rail, referenced to clean analog ground plane. Use Value: Avoids audible pop/click artifacts during ESD events by limiting leakage current to ≤1 µA at 24 V and clamping noise transients below ADC reference thresholds. | Use Scenario: Hardening RS-232/UART lines in ruggedized barcode scanners subjected to field ESD in warehouse environments. IC Role / Device Role / Timing Role: Point-of-entry TVS on serial interface pins, selected for stable VBR over -65°C to +150°C operating range. Use Value: Ensures uninterrupted communication during cold-start (-40°C) and hot-storage (+85°C) conditions without parameter drift-induced false triggering. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-Q | DO-214AC package (4.5 mm × 2.7 mm), 31 V VBR min, 500 W PPP, 400 pF CT | Higher capacitance limits use to DC/low-speed lines; larger size precludes space-constrained portable designs. | Select when board area is unconstrained and higher surge energy (500 W vs. 378 W) is required for industrial-level lightning immunity. |
| SP1003-02HTG | SOD-323 package (1.7 mm × 1.25 mm), 24 V VRWM, 30 kV ESD, 15 pF CT, 5 A IPP | Lower clamping voltage (28 V @ 5 A) but reduced surge capacity; better for ultra-high-speed SerDes where <20 pF is mandatory. | Choose for PCIe Gen3 or MIPI D-PHY interfaces where 15 pF capacitance is critical, accepting lower 5 A surge rating. |
Compared with SMAJ24A-Q and SP1003-02HTG, D24V0H1U2LP-7B uniquely balances ultra-small footprint (1.08 × 0.68 mm), moderate 47 pF capacitance, and 9 A surge capability-making it optimal for mid-speed data lines (USB 2.0, eMMC, SDIO) in space- and cost-sensitive consumer devices.

FAQ
What is the maximum operating temperature for D24V0H1U2LP-7B?
The device supports continuous operation from –65°C to +150°C. Its thermal derating curve shows power dissipation linearly decreases from 250 mW at 25°C to zero at 150°C, enabling reliable use in sealed enclosures with limited airflow, such as automotive infotainment bezels or outdoor IoT sensors.
Can D24V0H1U2LP-7B be used for bidirectional signal protection?
No-it is strictly unidirectional and must be oriented with cathode to ground and anode to the protected line. For bidirectional protection (e.g., USB D+/D−), two devices are required per line or a dedicated bidirectional TVS like D24V0L1U2LP must be selected to avoid forward conduction during normal signal swings.
How does the 47 pF capacitance affect USB 2.0 signal integrity?
At 480 Mbps, 47 pF introduces negligible insertion loss (<0.5 dB) and maintains eye diagram opening >70% when placed with <2 mm trace length from connector. Measured TLP curves confirm sub-1 ns response, preventing jitter accumulation or bit errors during ESD events on host/device ports.
Is D24V0H1U2LP-7B qualified for automotive applications?
While not AEC-Q200 qualified out-of-box, Diodes offers automotive-grade variants (e.g., D24V0H1U2LPQ-7B) with PPAP documentation, IATF 16949 manufacturing, and extended temperature screening. Standard D24V0H1U2LP-7B is widely used in non-safety-critical automotive accessories like dashcams and OBD-II dongles.
