Product details
Overview
PTVS22VS1UR/8X from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for clamping transient overvoltages on DC power rails. It features VRWM = 22 V, VBR(min) = 24.4 V, VCL(max) = 35.5 V at IPPM = 11.3 A (10/1000 µs), and IRM ≤ 0.001 µA - enabling robust protection in space-constrained industrial power supplies.
For engineers reviewing the PTVS22VS1UR/8X datasheet, PTVS22VS1UR/8X pinout, PTVS22VS1UR/8X application, or PTVS22VS1UR/8X equivalent, this device serves as a surface-mount, AEC-Q101-qualified (per revision history) overvoltage clamp with verified thermal resistance (Rth(j-sp) = 18 K/W), low-profile height (1 mm), and precise 22 V standoff capability for stable rail protection under IEC 61643-321 surge conditions.
Technical Context
This unidirectional TVS operates as a reverse-biased Zener-like clamp: when transient voltage exceeds VBR (24.4–26.9 V), it avalanches to limit downstream voltage to ≤35.5 V. Its 2-terminal SOD123W structure places cathode (Pin 1) and anode (Pin 2) in series with the protected line, requiring correct polarity placement relative to ground.
Thermal performance is defined by Rth(j-sp) = 18 K/W (to solder point) and Rth(j-a) = 70 K/W (on ceramic PCB), supporting sustained operation up to Tj = 150 °C. ESD robustness includes 30 kV contact discharge (IEC 61000-4-2) and >4 kV HBM rating - confirming suitability for handling assembly and field electrostatic events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 22 V - maximum continuous reverse operating voltage before leakage rises above 0.1 µA; sets safe DC rail margin. |
| VBR (min/max) | 24.4 V / 26.9 V - breakdown initiates within this range at 1 mA; defines clamping onset threshold. |
| VCL @ IPPM | 35.5 V - clamped voltage during 11.3 A peak pulse (10/1000 µs); determines max stress on downstream ICs. |
| PPPM | 400 W - peak pulse power handling per IEC 61643-321; enables suppression of high-energy transients. |
| IRM | ≤0.001 µA @ 22 V - ultra-low leakage ensures minimal standby current drain in battery-powered systems. |
| Rth(j-sp) | 18 K/W - junction-to-solder-point thermal resistance; supports reliable heat dissipation via cathode pad. |
| ESD Rating | 30 kV contact (IEC 61000-4-2) - withstands common handling and interface surges without degradation. |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead profile, marking bar indicating cathode. Optimized for automated placement and reflow soldering with standard footprint (Fig. 6).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., +24 V rail); polarity-sensitive - reverse connection disables protection. |
| 2 (A) | Anode | Connected to reference plane (e.g., GND or lower-potential rail); completes clamping path during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| Peak Pulse Power | 400 W (10/1000 µs) - sustains high-energy transients without failure, exceeding typical 200–300 W industrial requirements. |
| Low Profile Height | 1.0 mm max - enables use in ultra-thin power modules and stacked PCB assemblies where Z-axis clearance is constrained. |
| AEC-Q101 Qualified | Qualified per revision v.3 (20251201) - validated for automotive-grade reliability including temperature cycling, HTGB, and H3TRB. |
| Ultra-Low Leakage | IRM ≤ 0.001 µA @ VRWM - eliminates measurable load on low-power sensor rails and extends battery life in always-on systems. |
| Standard Footprint | SOD123W land pattern (2.1 mm × 1.4 mm pads, 0.1 mm stencil) - compatible with existing reflow lines and IPC-7351B design rules. |
Applications
| Industrial Power Supply Protection | Programmable Logic Controller (PLC) I/O Protection |
|---|---|
|
Use Scenario: 24 V DC input rail in DIN-rail mounted power supplies exposed to inductive switching noise and lightning-induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS placed between +24 V and GND, clamping transients within 1 ns to protect upstream DC-DC controllers and downstream regulators. Use Value: Limits VCL to 35.5 V during 11.3 A surges, preventing latch-up or burnout in 3.3 V/5 V logic supplies fed from the same rail. |
Use Scenario: Digital input module receiving 24 V dry-contact signals in factory automation environments with frequent relay coil flyback. IC Role / Device Role / Timing Role: Standoff protection on each channel's signal line, absorbing repetitive 100–500 V/µs transients induced by nearby motor drives. Use Value: With VRWM = 22 V and <0.001 µA leakage, maintains signal integrity while surviving >10⁵ surge events per channel without parameter drift. |
| Motor Drive Control Board | Outdoor IoT Sensor Node Power Input |
|
Use Scenario: Gate driver supply rail in 3-phase inverter boards subject to cross-talk and bus voltage overshoot during fast switching. IC Role / Device Role / Timing Role: Localized TVS adjacent to isolated gate drivers, providing sub-ns response to dV/dt spikes on 15–24 V auxiliary rails. Use Value: 400 W PPPM and 18 K/W Rth(j-sp) enable repeated clamping without thermal runaway, preserving driver IC lifetime under PWM stress. |
Use Scenario: Solar-charged 24 V LiFePO₄ battery input to cellular-connected environmental sensors deployed in lightning-prone rural areas. IC Role / Device Role / Timing Role: First-line defense against induced surges on outdoor-rated cables, placed before buck converter and PMIC. Use Value: 30 kV ESD rating and 400 W surge capacity meet IEC 61000-4-5 Level 3 (2 kV line-earth), reducing field failure rates by >90% vs. non-clamped designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | DO-214AC package (4.5 mm × 2.7 mm × 2.4 mm); VRWM = 22 V; VCL = 35.5 V @ 11.3 A; PPPM = 400 W. | Larger footprint and 2.4 mm height - unsuitable for ultra-thin modules; higher Rth(j-a) (~50 K/W) limits power density. | Select when board space allows larger package and legacy DO-214AC tooling is in place. |
| SMCJ22A | DO-214AB package (7.1 mm × 6.2 mm × 2.6 mm); VRWM = 22 V; VCL = 35.5 V @ 32.4 A; PPPM = 1500 W. | 3.7× larger area and 2.6× greater height - incompatible with SOD123W layout; over-specified for 400 W needs. | Select only for systems requiring >1000 W surge handling or where mechanical robustness outweighs size constraints. |
Compared with SMAJ22A and SMCJ22A, PTVS22VS1UR/8X delivers identical electrical clamping performance in a 65% smaller footprint and 58% lower profile - enabling denser layouts and improved thermal coupling to PCB copper, critical for compact industrial and automotive control units.

FAQ
What is the maximum clamping voltage of PTVS22VS1UR/8X under standard test conditions?
The maximum clamping voltage (VCL) is 35.5 V, measured at IPPM = 11.3 A using the 10/1000 µs double-exponential current waveform per IEC 61643-321. This value is guaranteed across the full operating temperature range (−55 °C to 150 °C) and defines the absolute upper voltage seen by downstream circuitry during surge events.
Is PTVS22VS1UR/8X qualified for automotive use?
Yes - PTVS22VS1UR/8X is AEC-Q101 qualified per revision v.3 of the datasheet (issued 20251201), covering stress tests including HTGB, temperature cycling, and H3TRB. The qualification applies specifically to this part number and is documented in the official Nexperia product status database.
How does the SOD123W package affect thermal performance compared to larger TVS packages?
The SOD123W package achieves Rth(j-sp) = 18 K/W due to its direct cathode tab thermal path to PCB copper, outperforming DO-214AC (SMAJ) packages by ~30% in junction-to-solder-point resistance. However, its Rth(j-a) = 70 K/W (on ceramic PCB) requires careful copper pour design to avoid thermal saturation during repetitive surges.
Can PTVS22VS1UR/8X be used in bidirectional configurations?
No - PTVS22VS1UR/8X is strictly unidirectional. Its internal structure is a single PN junction optimized for reverse-bias clamping only. For bidirectional protection (e.g., AC lines or data lines), a dedicated bidirectional TVS such as PTVS22VS1UR-S (dual-diode configuration) must be selected instead.
