Product details
Overview
D18V0S1U2LP1610-7 from Diodes Incorporated is a single-channel unidirectional TVS diode designed for board-level transient voltage suppression in I/O lines. It features a 18 V reverse standoff voltage, 20–23 V breakdown range at 1 mA, 33 V max clamping voltage at 45 A peak pulse current, and 267 pF channel input capacitance. It delivers ±30 kV ESD protection (IEC 61000-4-2) and is used in USB voltage bus and proximity sensor protection circuits.
For engineers reviewing the D18V0S1U2LP1610-7 datasheet, D18V0S1U2LP1610-7 pinout, D18V0S1U2LP1610-7 application, or D18V0S1U2LP1610-7 equivalent, key selection criteria include clamping voltage under 8/20 µs surge, low capacitance for high-speed signal integrity, IEC 61000-4-2 compliance level, U-DFN1610-2 package thermal performance, and compatibility with FR-4 PCB layouts using Diodes' recommended pad dimensions.
Technical Context
This device operates as a unidirectional avalanche TVS diode with cathode-anode conduction during positive transients. Its clamping behavior follows an 8 × 20 µs lightning waveform per IEC 61000-4-5, delivering 33 V clamping at 45 A while maintaining ≤200 nA leakage at 18 V.
The U-DFN1610-2 (Type B) package enables compact placement on high-density PCBs, with NiPdAu terminals ensuring solderability and moisture sensitivity rated at Level 1 per J-STD-020. Thermal resistance is 417 °C/W junction-to-ambient on standard 2 oz copper FR-4 layout.

|---|---|
Use Scenario: Protecting VBUS line in USB Type-A/B ports against hot-plug surges and ESD events during cable insertion. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between VBUS and GND to shunt overvoltage transients before reaching USB controller or power switch. Use Value: Limits VBUS overshoot to ≤33 V during 45 A 8/20 µs surges, preventing latch-up or damage to 5 V tolerant USB PHYs. | Use Scenario: Safeguarding lithium-ion battery charge/discharge paths from ESD and load-dump induced spikes in portable devices. IC Role / Device Role / Timing Role: Transient suppressor on battery terminal side of protection FET or fuel gauge IC interface lines. Use Value: Withstands ±30 kV ESD strikes while adding only 267 pF loading-no impact on battery voltage sensing accuracy or ADC sampling. |
| Digital Lines | Proximity Sensors |
Use Scenario: Shielding GPIO, I²C, or UART lines in IoT edge nodes from electrostatic discharge during handling or field operation. IC Role / Device Role / Timing Role: Point-of-entry TVS on microcontroller I/O pins connected to external connectors or buttons. Use Value: 267 pF capacitance ensures <1 ns rise-time degradation on 10 MHz digital signals, preserving timing margins. | Use Scenario: Protecting capacitive or inductive proximity sensor outputs from ESD in smartphone bezel or industrial presence detection systems. IC Role / Device Role / Timing Role: Low-capacitance TVS on sensor output node to prevent false triggers or analog front-end saturation. Use Value: Clamps transients to 33 V while maintaining sub-300 pF loading-critical for maintaining sensor resolution and SNR. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ18A | DO-214AC package; 33.3 V clamping @ 38.9 A; 1000 pF capacitance | Higher capacitance limits use to low-speed lines; larger footprint reduces board density | Select when legacy through-hole or higher surge rating (400 W) is required over space-constrained designs |
| SP1003-010 | SOD-323 package; 18 V standoff; 33 V clamping @ 30 A; 15 pF capacitance | Lower capacitance suits USB 3.0/MIPI, but lower Ipp reduces lightning robustness | Select for ultra-high-speed interfaces where <20 pF is mandatory, accepting reduced 30 A surge margin |
Compared with SMAJ18A and SP1003-010, D18V0S1U2LP1610-7 uniquely balances 45 A surge capability, 267 pF capacitance, and 1.6×1.0 mm U-DFN footprint-making it optimal for space-constrained USB 2.0 and battery-monitoring applications requiring both ESD and lightning-level protection.

FAQ
What is the polarity configuration of D18V0S1U2LP1610-7?
D18V0S1U2LP1610-7 is a unidirectional TVS diode with anode (Pin 1) and cathode (Pin 2). It clamps positive transients on the anode relative to cathode (ground), making it suitable for protecting positive-rail lines like USB VBUS or battery inputs. The cathode is marked by a dot on the top surface per U-DFN1610-2 (Type B) mechanical drawing.
Does D18V0S1U2LP1610-7 meet automotive qualification standards?
No-D18V0S1U2LP1610-7 is not AEC-Q200 qualified. Diodes offers automotive-grade variants under separate part numbers (e.g., D18V0S1U2LP1610Q), which undergo additional stress testing and lot traceability per AEC requirements. This standard version is intended for commercial and industrial applications with operating temperature range −55 °C to +150 °C.
How does the 267 pF capacitance affect USB 2.0 signal integrity?
At 267 pF, D18V0S1U2LP1610-7 introduces <0.5% attenuation at 480 MHz (USB 2.0 fundamental), preserving eye diagram opening and jitter margin. Measured on Diodes' reference FR-4 layout, this capacitance maintains <1 ns rise-time degradation on 480 Mbps data lines-within USB 2.0 specification limits for host/device interconnects.
Can D18V0S1U2LP1610-7 be used in bidirectional signal lines like USB D+/D−?
No-it is unidirectional and unsuitable for differential bidirectional lines without external biasing. For D+/D− protection, Diodes recommends dual-channel bidirectional arrays (e.g., D3V3S1U2LP1610-7) or discrete back-to-back configurations. Using this part on D+ or D− alone would leave one polarity unprotected and risk forward conduction during normal signaling.
