Product details
Overview
D22V0S1U2LP1610-7 from Diodes Incorporated is a single-channel unidirectional TVS diode designed for board-level transient voltage suppression in I/O lines. It features a 22 V reverse standoff voltage, 24–28 V breakdown range at 1 mA, 38 V clamping voltage at 32 A peak pulse current, and 226 pF channel input capacitance - enabling robust ESD protection (±30 kV contact/air) while preserving signal integrity in USB voltage bus and proximity sensor interfaces.
For engineers reviewing the D22V0S1U2LP1610-7 datasheet, D22V0S1U2LP1610-7 pinout, D22V0S1U2LP1610-7 application, or D22V0S1U2LP1610-7 equivalent, key selection criteria include clamping voltage vs. surge current trade-off, low capacitance for high-speed data lines, U-DFN1610-2 footprint compatibility, and compliance with IEC 61000-4-2/4-5 for mobile and battery-powered systems.
Technical Context
This TVS diode operates as a unidirectional clamping device between an I/O line and ground, triggered by overvoltage transients exceeding its breakdown threshold. Its silicon avalanche structure delivers fast response (<1 ns), low dynamic impedance, and stable clamping under 8/20 µs lightning surges up to 32 A.
The device is optimized for space-constrained PCB layouts with its 1.6 mm × 1.0 mm U-DFN1610-2 (Type B) package and dual-terminal configuration. Thermal performance is characterized by 417 °C/W junction-to-ambient resistance on standard FR-4 with 2 oz copper, supporting continuous operation from –55 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 22 V - Maximum continuous DC operating voltage before leakage exceeds 200 nA; sets safe margin below system rail. |
| Breakdown Voltage Range | 24–28 V @ 1 mA - Confirmed avalanche onset window; ensures reliable triggering without premature conduction. |
| Clamping Voltage | 38 V @ 32 A (8/20 µs) - Peak voltage seen by protected circuit during worst-case surge; limits stress on downstream ICs. |
| Peak Pulse Current | 32 A - Maximum transient current the device safely shunts without degradation; validated per IEC 61000-4-5. |
| Channel Input Capacitance | 226 pF @ 0 V, 1 MHz - Measured I/O-to-GND; enables use on USB 2.0 and digital sensor lines without signal distortion. |
| ESD Withstand | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - Full immunity to human-body-model ESD events in handheld and accessory designs. |
Pinout & Package
Package: U-DFN1610-2 (Type B), 1.6 mm × 1.0 mm × 0.5 mm, dual-terminal surface-mount, NiPdAu-plated terminals, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to protected I/O line; current flows from I/O to ground during overvoltage event. |
| Pin 2 | Cathode | Connected to system ground; defines unidirectional clamping polarity and reference node. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 ESD Protection | ±30 kV contact and air discharge - eliminates need for external ESD staging in consumer-grade USB and sensor ports. |
| Low Channel Input Capacitance | 226 pF - preserves signal rise/fall times on 480 Mbps USB 2.0 and 100 kHz–1 MHz digital sensor buses. |
| High Surge Current Capability | 32 A peak pulse (8/20 µs) - withstands multiple lightning-induced transients per IEC 61000-4-5 without parametric shift. |
| Green Packaging | Halogen- and antimony-free, RoHS 3 compliant - meets automotive and industrial environmental compliance requirements without derating. |
Applications
| USB Voltage Bus Protection | Battery Protection Circuit |
|---|---|
Use Scenario: Protecting VBUS line in portable USB-C accessories against hot-plug surges and charger-induced transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamp between VBUS and GND, activated only during overvoltage events above 22 V. Use Value: Limits VBUS excursion to ≤38 V during 32 A surges, preventing damage to USB power switches and load switches rated for 28 V max. | Use Scenario: Safeguarding lithium-ion battery management IC inputs from ESD during assembly and field handling. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor on battery voltage monitor (VBAT_SENSE) line. Use Value: 226 pF capacitance avoids filtering of DC-sense signals, while ±30 kV ESD rating prevents latch-up in precision ADC front-ends. |
| Proximity Sensor Interface | Mobile Handset I/O Protection |
Use Scenario: Shielding capacitive proximity sensor output (e.g., IR LED driver feedback) from ESD in smartphone bezel zones. IC Role / Device Role / Timing Role: Signal-line TVS placed directly at sensor IC pad, minimizing trace inductance for sub-nanosecond response. Use Value: 38 V clamping ensures sensor analog output stays within 0–3.3 V ADC range even during direct ESD strikes. | Use Scenario: Board-level protection of headphone jack, SIM card slot, and side-button lines in IP67-rated handsets. IC Role / Device Role / Timing Role: Discrete TVS per I/O path, leveraging U-DFN1610-2's small footprint to fit tight mechanical clearances. Use Value: Dual-terminal layout allows placement within 0.5 mm of connector pads, reducing parasitic inductance and improving clamping efficacy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | DO-214AC package (4.5 mm × 2.7 mm); 38.9 V clamping @ 32.4 A; 500 pF capacitance | Higher capacitance limits use to low-speed lines; larger footprint consumes 6× more board area | Select when legacy through-hole or larger SMT footprint is acceptable and capacitance >400 pF is tolerable. |
| TPD2E001DRYR | 2-channel, 15 pF per channel, 12 V standoff; 12 V clamping @ 4 A; SC-70-6 package | Lower surge rating (4 A) and lower voltage rating limit use to low-energy signal lines only | Select for ultra-low-capacitance differential signal protection where peak current <5 A suffices. |
Compared with SMAJ22A and TPD2E001DRYR, D22V0S1U2LP1610-7 uniquely balances 226 pF capacitance, 32 A surge capability, and 1.6 mm × 1.0 mm footprint - making it optimal for space-constrained, medium-energy I/O protection in USB and battery-sensing applications.

FAQ
What is the maximum operating temperature for D22V0S1U2LP1610-7?
D22V0S1U2LP1610-7 is rated for continuous operation from –55 °C to +150 °C ambient temperature. This range is validated per JESD22-A104 and supports deployment in automotive cabin modules, industrial sensors, and battery packs where thermal cycling and elevated temperatures occur.
Does D22V0S1U2LP1610-7 meet automotive qualification standards?
No - D22V0S1U2LP1610-7 is not AEC-Q200 qualified. Automotive-grade variants exist under separate part numbers (e.g., D22V0S1U2LP1610Q), which include extended temperature screening, enhanced reliability testing, and PPAP documentation per IATF 16949.
How does the U-DFN1610-2 package affect PCB layout?
The U-DFN1610-2 (Type B) requires a specific two-pad footprint with 1.10 mm pitch and thermal pad clearance. Diodes provides a recommended pad layout (document DS41425, page 5) that minimizes solder voiding and ensures thermal reliability - critical for maintaining 417 °C/W RθJA under surge conditions.
Can D22V0S1U2LP1610-7 be used for bidirectional protection?
No - D22V0S1U2LP1610-7 is unidirectional. Its schematic symbol and pinout (anode/cathode) confirm single-quadrant clamping from I/O to ground. For bidirectional protection, Diodes offers the D22V0S1B2LP1610-7 variant in the same package, with symmetrical ±22 V standoff.
