Product details
Overview
D22V0H1U2LP1610 from Diodes Incorporated is a single-channel, ultra-low-capacitance TVS diode designed for ESD protection of high-speed data lines in portable electronics. It features a 22 V reverse standoff voltage (VRWM), 23.5 V minimum breakdown voltage (VBR), 200 pF typical channel capacitance (CT), and clamps transients to ≤37 V at 28 A peak pulse current (IPP), making it suitable for USB 2.0, HDMI, and audio jack interfaces.
For engineers reviewing the D22V0H1U2LP1610 datasheet, D22V0H1U2LP1610 pinout, D22V0H1U2LP1610 application, or D22V0H1U2LP1610 equivalent, key selection criteria include IEC 61000-4-2 ±30 kV contact/air ESD rating, U-DFN1610-2 footprint compatibility, low dynamic resistance (0.05 Ω), and thermal derating behavior across –55°C to +150°C operating range.
Technical Context
This unidirectional TVS diode operates in avalanche breakdown mode to shunt ESD energy away from sensitive I/O pins. Its low 200 pF input capacitance preserves signal integrity on high-frequency lines, while its 0.05 Ω dynamic resistance ensures rapid voltage clamping during sub-nanosecond transients.
The device is optimized for surface-mount integration in space-constrained portable designs, with thermal performance validated on 2 oz copper FR-4 PCBs (RθJA = 417°C/W) and rated for 1000 W peak pulse power (8/20 µs waveform) at 25°C ambient.
Key Specifications

|---|---|
| VRWM | 22 V - Maximum continuous reverse voltage before leakage exceeds 200 nA; sets upper limit for protected line DC bias. |
| VBR (min) | 23.5 V @ 1 mA - Ensures reliable triggering above system operating voltage to avoid false clamping. |
| VC @ 28 A | 35–37 V - Clamping voltage under worst-case IEC 61000-4-5 lightning surge; defines maximum stress on downstream IC. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | DO-214AC package (4.5 mm × 2.7 mm); 22 V VRWM; 33.2 V VC @ 28 A; 350 pF CT | Larger footprint; higher capacitance limits use to DC/low-speed lines only | Select when board space allows larger package and ESD threat is lower-energy (e.g., non-handheld equipment). |
| SP1003-02UTG | SOD-523 package (1.3 mm × 0.85 mm); 22 V VRWM; 30 V VC @ 28 A; 110 pF CT | Smaller size but lower IPP (20 A); not qualified to IEC 61000-4-2 ±30 kV | Choose where ultra-low capacitance is critical and ESD exposure is limited to ±15 kV environments. |
Compared with SMAJ22A and SP1003-02UTG, D22V0H1U2LP1610 uniquely balances ultra-small U-DFN1610-2 size, ±30 kV ESD rating, and 200 pF capacitance-enabling direct replacement in next-gen portable designs without layout redesign or signal integrity compromise.

FAQ
What is the maximum clamping voltage of D22V0H1U2LP1610 under full-rated surge current?
The clamping voltage is 35–37 V at 28 A peak pulse current (8/20 µs waveform), measured per IEC 61000-4-5 test conditions. This value reflects worst-case transient suppression performance and defines the absolute maximum voltage seen by protected circuitry during a full-surge event.
Can D22V0H1U2LP1610 be used for bidirectional signal lines like USB D+/D–?
No-D22V0H1U2LP1610 is a unidirectional TVS diode intended for DC-biased lines (e.g., HDMI HPD, audio MIC bias). For true bidirectional protection such as USB 2.0 differential pairs, a symmetric dual-channel device like D24V0H1U2LP1610 is required.
Is the U-DFN1610-2 package thermally enhanced with an exposed pad?
No-the U-DFN1610-2 (Type B) package used for D22V0H1U2LP1610 has no electrically or thermally active exposed pad. Thermal dissipation relies solely on solder joint conduction through Pins 1 and 2 to internal copper planes, with RθJA = 417°C/W measured on standard 2 oz FR-4.
Does this device meet AEC-Q200 for automotive use?
No-D22V0H1U2LP1610 is not AEC-Q200 qualified. Diodes Incorporated states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing; users needing automotive qualification must contact Diodes directly for approved alternatives such as the AEC-Q200-compliant D22V0H1Q2LP1610 variant.
