Product details
Overview
PTVS22VS1UR,115 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 - deployed in industrial power supply protection circuits where space-constrained board layout and low-profile mounting are critical.
For engineers reviewing the PTVS22VS1UR,115 datasheet, PTVS22VS1UR,115 pinout, PTVS22VS1UR,115 application, or PTVS22VS1UR,115 equivalent, this device is selected for robust 22 V rail protection with sub-1 mm height, AEC-Q101 qualification status confirmed per revision v.4 (2025), and verified thermal resistance to solder point (Rth(j-sp) = 18 K/W) enabling reliable operation up to 150 °C junction temperature.
Technical Context
This unidirectional TVS operates as a clamping diode in reverse-biased configuration: under normal conditions it presents high impedance (IRM ≤ 0.001 µA at VRWM), but triggers avalanche conduction when transient voltage exceeds VBR (24.4–26.9 V), limiting downstream voltage to ≤35.5 V at 11.3 A peak pulse current. Its IEC 61643-321-compliant 10/1000 µs waveform rating ensures compatibility with standard surge immunity test profiles.
The SOD123W package enables surface-mount integration with minimal PCB footprint (2.6 × 1.7 × 1.0 mm) and optimized thermal path to solder point (18 K/W), supporting high-reliability operation in ambient temperatures from –55 °C to +150 °C and junction temperatures up to 150 °C - validated per AEC-Q101 stress testing for discrete semiconductors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 22 V - maximum continuous reverse operating voltage before leakage rises significantly; defines safe DC rail voltage margin. |
| VBR (min) | 24.4 V - minimum breakdown voltage at 1 mA; guarantees reliable triggering above nominal rail. |
| VCL (max) | 35.5 V - maximum clamped voltage at IPPM = 11.3 A; determines peak stress on protected ICs. |
| PPPM | 400 W - rated peak pulse power (10/1000 µs); quantifies single-event surge energy handling capability. |
| IRM | ≤0.001 µA - reverse leakage at VRWM; ensures negligible standby power loss and signal integrity. |
| Rth(j-sp) | 18 K/W - thermal resistance from junction to cathode solder point; enables effective heat dissipation in compact layouts. |
| ESD Rating | 30 kV (IEC 61000-4-2 contact discharge); provides system-level ESD robustness without external shielding. |

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 | Same VRWM (22 V), lower PPPM (400 W vs. SMAJ22A's 400 W), but larger SMA package (4.5 × 2.7 × 2.2 mm) and higher Rth(j-a) (50 K/W). | Not suitable for ultra-low-profile designs; requires more PCB area and exhibits higher thermal rise under repeated surges. | Select PTVS22VS1UR,115 when board height < 1.1 mm or thermal performance at high ambient is critical. |
| 1.5SMC22A | Higher PPPM (1500 W), but DO-214AB package (7.1 × 6.2 × 2.3 mm); 10× larger footprint and 3× taller than SOD123W. | Used where extreme surge energy dominates size constraints - e.g., main AC/DC input stages, not point-of-load rails. | Choose PTVS22VS1UR,115 for space-limited point-of-load protection; use 1.5SMC22A only for front-end bulk surge suppression. |
Compared with SMAJ22A and 1.5SMC22A, PTVS22VS1UR,115 delivers identical 22 V standoff and 400 W surge rating in a package that reduces board area by 85% and height by 55%, while offering 3× better thermal coupling to PCB - making it optimal for dense, thermally constrained industrial and automotive ECUs.

FAQ
What is the maximum clamping voltage of PTVS22VS1UR,115 under a 10/1000 µs surge?
The maximum clamping voltage (VCL) is 35.5 V at IPPM = 11.3 A, measured per IEC 61643-321 using the standardized 10/1000 µs current waveform. This value is guaranteed across the full operating temperature range (–55 °C to +150 °C) and defines the upper voltage limit imposed on protected circuitry during transient events.
Is PTVS22VS1UR,115 qualified for automotive use per AEC-Q101?
Yes - PTVS22VS1UR,115 is explicitly listed in the revision v.4 (December 2025) data sheet as AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias, temperature cycling, and ESD per Rev G requirements. The revision history confirms its inclusion in the 33-product group retaining automotive qualification status.
How does the SOD123W package affect thermal performance compared to SMA or DO-214AB?
The SOD123W package achieves Rth(j-sp) = 18 K/W - significantly lower than SMA (≈50 K/W) or DO-214AB (≈30 K/W) - due to its direct cathode tab connection to PCB copper. This enables faster heat transfer from junction to board, reducing steady-state temperature rise by up to 40% under repetitive surge conditions on standard FR4 layouts.
Can PTVS22VS1UR,115 be used in bidirectional configurations?
No - PTVS22VS1UR,115 is a unidirectional TVS diode with anode and cathode terminals; it conducts only during negative transients relative to its cathode. For bidirectional protection (e.g., AC lines or data lines), a separate symmetric device such as PTVS22VS1UR,115 paired with a second unit in anti-parallel, or a dedicated bidirectional part like PTVS22VS1UTR, is required.
