Product details
Overview
PTVS22VS1UTR from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature overvoltage protection in power rails. It features VRWM = 22 V, VBR(min) = 24.4 V at 1 mA, VCL = 35.5 V at IPPM = 11.3 A (10/1000 µs), and operates up to Tj = 185 °C - enabling robust surge suppression in industrial power management systems.
For engineers reviewing the PTVS22VS1UTR datasheet, PTVS22VS1UTR pinout, PTVS22VS1UTR application, or PTVS22VS1UTR equivalent, this device delivers verified clamping performance, thermal stability beyond 150 °C ambient, low-profile surface-mount compatibility, and ESD immunity up to 30 kV (IEC 61000-4-2 contact discharge).
Technical Context
This unidirectional TVS diode uses an avalanche breakdown mechanism to clamp transient overvoltages above its reverse standoff voltage (VRWM = 22 V). Its VBR range (24.4–26.9 V at 1 mA) ensures precise triggering while maintaining low leakage (IRM ≤ 0.001 µA at VRWM).
Thermal design is enabled by Rth(j-sp) = 18 K/W to cathode solder point and rated junction temperature of 185 °C - supporting operation in enclosed, high-ambient environments such as motor drives and power supply front-ends where airflow is limited.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 22 V reverse standoff voltage - defines maximum continuous DC operating voltage before clamping initiates |
| VBR (min/max) | 24.4 V / 26.9 V at 1 mA - guarantees reliable avalanche turn-on within tight tolerance for predictable protection threshold |
| VCL @ IPPM | 35.5 V at 11.3 A (10/1000 µs) - limits downstream voltage stress during 400 W transient events |
| PPPM | 400 W peak pulse power - sustains IEC 61643-321-compliant surges without degradation |
| Tj max | 185 °C - enables use in under-hood, furnace control, or sealed industrial enclosures without derating |
| ESD rating | 30 kV contact discharge (IEC 61000-4-2) - eliminates need for additional ESD front-end stages in board-level designs |
| Rth(j-sp) | 18 K/W - allows direct thermal coupling to PCB copper for efficient heat dissipation in compact layouts |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2.6 mm × 1.7 mm × 1.0 mm body height; flat lead profile optimized for automated placement and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., +24 V rail); marking bar on package identifies this terminal |
| 2 (A) | Anode | Connected to ground reference; completes clamping path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction-rated to 185 °C - supports uninterrupted protection in environments exceeding 125 °C ambient |
| Low-profile SMD package | 1.0 mm max height - enables use in space-constrained power modules and stacked PCB assemblies |
| Precision clamping window | VBR spread ≤ 2.5 V (24.4–26.9 V) - minimizes risk of false triggering or insufficient protection margin |
| Ultra-low leakage | IRM ≤ 0.001 µA at VRWM - prevents measurable power loss or signal distortion in always-on monitoring circuits |
| Robust ESD immunity | 30 kV contact discharge rating - withstands handling and system-level ESD without parameter shift or failure |
Applications
| Industrial Motor Drives | Programmable Logic Controller (PLC) I/O Modules |
|---|---|
Use Scenario: Protection of 24 V DC input/output lines against inductive kickback from solenoids and relay coils. IC Role / Device Role / Timing Role: Unidirectional TVS placed between field-side 24 V rail and ground to clamp transients up to 400 W.

Use Scenario: Guarding analog input channels (e.g., 4–20 mA loops) against wiring-induced surges in factory-floor cabinets. IC Role / Device Role / Timing Role: Standoff-mode protector on signal return path, leveraging 22 V VRWM to avoid interference with normal 20 mA loop operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | Lower PPPM (400 W same), but VRWM = 22 V, VCL = 35.5 V, Tj max = 150 °C | Limited to ≤125 °C ambient due to lower junction rating; requires thermal derating above 85 °C | Select when cost sensitivity outweighs high-temperature requirement and board layout permits larger footprint |
| SMCJ22A | Same VRWM/VCL, but higher PPPM (1500 W), larger DO-214AB package (7.11 mm × 6.22 mm), Tj max = 175 °C | Offers higher surge margin but occupies >5× PCB area; less suitable for dense industrial modules | Choose for extreme surge environments (e.g., outdoor substations) where size is secondary to energy absorption |
Compared with SMAJ22A and SMCJ22A, PTVS22VS1UTR uniquely balances 400 W surge capability, 1 mm profile, and 185 °C junction rating - making it optimal for thermally constrained, high-reliability industrial PCBs where both space and temperature margins are critical.

FAQ
What is the maximum clamping voltage of PTVS22VS1UTR under standard test conditions?
The clamping voltage VCL is 35.5 V at a peak pulse current IPPM of 11.3 A, measured using the 10/1000 µs waveform per IEC 61643-321. This value is guaranteed across the full operating temperature range and represents the maximum voltage seen by downstream circuitry during a 400 W transient event.
Can PTVS22VS1UTR be used in automotive applications?
No - PTVS22VS1UTR is not AEC-Q200 qualified and lacks automotive-specific testing or qualification. Nexperia explicitly states non-automotive qualification in its legal disclaimers. For automotive use, select a designated AEC-Q200-compliant TVS such as the PTVS22VS1UTR-Q series, if available.
How does the 185 °C junction rating translate to practical PCB design?
The 185 °C Tj rating allows sustained operation at ambient temperatures up to 150 °C when properly mounted - verified via Rth(j-sp) = 18 K/W to cathode solder point. Designers must use ≥1 cm² copper pour under the cathode pad and follow Nexperia's SOD123W reflow footprint (Fig. 6) to achieve this rating without forced cooling.
Is the marking code 'CM' on the device body sufficient for identification?
Yes - per Table 4 of the datasheet, 'CM' is the official marking code for PTVS22VS1UTR. The cathode is indicated by a bar adjacent to pin 1, consistent with SOD123W standard orientation. No additional date or lot codes are required for functional identification in production traceability.
