Product details
Overview
D4V5H1U2LP1610-7 from Diodes Incorporated is a single-channel unidirectional TVS diode engineered for high-surge transient suppression in low-capacitance signal lines. It delivers 5.5V reverse breakdown voltage, clamps to ≤13V at 90A (8/20μs), exhibits 800pF typical input capacitance, and withstands ±30kV IEC 61000-4-2 ESD strikes - ideal for protecting touch panel data lines against electrostatic discharge and lightning-induced surges.
For engineers reviewing the D4V5H1U2LP1610-7 datasheet, D4V5H1U2LP1610-7 pinout, D4V5H1U2LP1610-7 application, or D4V5H1U2LP1610-7 equivalent, key selection criteria include clamping voltage at 90A surge, sub-1nF channel capacitance for high-speed interfaces, U-DFN1610-2 footprint compatibility, and automotive-grade variant availability (D4V5H1U2LP1610Q).
Technical Context
This TVS diode operates as a unidirectional clamping device between an I/O line and ground, leveraging avalanche breakdown to divert surge current away from protected circuitry. Its low dynamic resistance (0.05Ω) ensures minimal voltage overshoot during fast transients, while its 4.5V standoff voltage enables compatibility with 3.3V and 5V logic rails without leakage-induced power loss.
The device is optimized for IEC 61000-4-2 (±30kV contact/air) and IEC 61000-4-5 (90A, 8/20μs) compliance, with thermal design validated on 2oz FR-4 PCBs. Its U-DFN1610-2 (Type B) package supports high-density layout in space-constrained modules such as small panel controllers and portable HMI interfaces.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | DO-214AC package; 5.0V VRWM; 100A IPP; 1000pF CT | Larger footprint (4.5×2.7mm); higher capacitance limits use on >100MHz signals | Select when board space allows larger package and higher surge rating is prioritized over capacitance. |
| TPD1E10B06DPYR | UQFN-2 package; 5.5V VBR; 4A IPP; 0.6pF CT | Lower surge rating (4A vs. 90A); suited only for ESD-only, not lightning-level transients | Choose only for pure ESD protection in ultra-high-speed interfaces where sub-1pF capacitance is mandatory. |
Compared with SMAJ5.0A and TPD1E10B06DPYR, D4V5H1U2LP1610-7 uniquely balances 90A surge capability, 800pF capacitance, and 1.6×1.0mm footprint - making it optimal for space-constrained industrial HMIs requiring both ESD and IEC 61000-4-5 compliance.

FAQ
What is the maximum clamping voltage at 90A surge current?
The D4V5H1U2LP1610-7 clamps to a maximum of 13V under 90A, 8/20μs surge conditions per IEC 61000-4-5. This value is measured with the device mounted on a standard 2oz FR-4 PCB per Diodes' recommended pad layout, ensuring realistic thermal and electrical performance in production assemblies.
Is this TVS diode suitable for bidirectional signal lines like USB D+ and D−?
No - D4V5H1U2LP1610-7 is unidirectional and intended for protection between a signal line and ground. For bidirectional differential pairs such as USB 2.0, two devices are required (one per line), or a dedicated bidirectional array like D5V0F4U2LP4-7 should be used instead.
Does the U-DFN1610-2 package support automated optical inspection (AOI)?
Yes - the U-DFN1610-2 (Type B) package features visible pin 1 identification via a molded notch and a flat, coplanar leadframe surface. Its 0.9mm terminal width and 1.1mm pitch enable reliable AOI detection using standard 10-micron resolution systems calibrated for DFN packages.
How does the automotive-grade variant D4V5H1U2LP1610Q differ?
The D4V5H1U2LP1610Q is identical in electrical and mechanical specifications but qualified to AEC-Q101 standards, with extended temperature testing (−40°C to +125°C junction), enhanced process controls, and certified PPAP documentation - required for automotive infotainment and body control module deployments.
