Product details
Overview
PTVS14VS1UR,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 14 V reverse standoff voltage (VRWM), 17.2 V maximum clamping voltage (VCL) at 17.2 A peak pulse current (IPPM), and 0.001 µA reverse leakage at VRWM - enabling robust protection in space-constrained industrial and power management circuits.
For engineers reviewing the PTVS14VS1UR,115 datasheet, PTVS14VS1UR,115 pinout, PTVS14VS1UR,115 application, or PTVS14VS1UR,115 equivalent, key selection criteria include clamping performance under IEC 61643-321 10/1000 µs waveform, thermal resistance to solder point (18 K/W), AEC-Q101 qualification status per revision history, and compatibility with standard SOD123W reflow footprints.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping device in parallel with protected circuitry, triggering conduction when transient voltage exceeds its breakdown threshold (VBR = 15.6–17.2 V). Its low 1 mm profile and 2.6 mm × 1.7 mm footprint support high-density PCB layouts without compromising surge handling.
It complies with IEC 61643-321 for 10/1000 µs waveform testing and delivers 400 W rated peak pulse power (PPPM) at Tj = 25 °C, derating to ~220 W at 125 °C per typical junction temperature curve. The cathode-anode polarity is marked by a bar on the SOD123W body.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 14 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/typ/max) | 15.6 / 16.4 / 17.2 V - breakdown voltage range at 1 mA test current; defines turn-on threshold |
| VCL (max) | 23.2 V - maximum clamped voltage at IPPM = 17.2 A, limiting stress on downstream ICs |
| IPPM | 17.2 A - peak pulse current supported under 10/1000 µs waveform at VRWM |
| IRM | 0.001 µA - ultra-low reverse leakage ensures minimal standby power loss |
| Rth(j-sp) | 18 K/W - thermal resistance from junction to solder point enables effective heat dissipation via cathode pad |
| ESD Rating | 30 kV (IEC 61000-4-2 contact discharge) - supports robust handling in manufacturing and field environments |

Use Scenario: Battery-powered environmental sensor node with integrated RS-485 interface and LDO regulator. IC Role / Device Role / Timing Role: Low-profile TVS on 3.3 V or 5 V supply rail to suppress ESD and coupling noise from communication lines. Use Value: 1 mm height allows co-location with small-signal ICs on dense 4-layer sensor PCBs while delivering 30 kV contact ESD immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ14A | DO-214AC package (4.5 mm × 2.7 mm), 400 W PPPM, VBR = 15.6–17.2 V, VCL = 23.2 V, but Rth(j-a) = 59 K/W vs. 70 K/W for PTVS14VS1UR | Larger footprint; less suitable for ultra-dense layouts; higher thermal resistance limits sustained surge duty cycle | Select when board space permits and legacy DO-214AC footprint is standardized |
| 1.5SMC14A | DO-214AB package (7.1 mm × 6.2 mm), 1500 W PPPM, VBR = 15.6–17.2 V, VCL = 23.2 V, but 2.3 mm height and 10× larger area | Higher surge capacity but incompatible with SOD123W layout; not viable for miniaturized designs | Choose only for high-energy industrial surge environments where size is secondary to energy absorption |
Compared with SMAJ14A and 1.5SMC14A, PTVS14VS1UR,115 delivers identical clamping performance in a 65% smaller footprint and 30% lower thermal resistance to solder point - making it optimal for next-generation compact, thermally managed power protection.

FAQ
What is the maximum clamping voltage of PTVS14VS1UR,115 under specified test conditions?
The maximum clamping voltage (VCL) is 23.2 V, measured at a peak pulse current (IPPM) of 17.2 A using the IEC 61643-321 10/1000 µs waveform. This value ensures downstream components experience limited overvoltage stress during transient events, and is confirmed in Table 8 of the official Nexperia datasheet revision v.4 (December 2025).
Is PTVS14VS1UR,115 qualified for automotive applications?
Yes - per revision history v.4 (2025), PTVS14VS1UR,115 retains AEC-Q101 qualification for discrete semiconductors, covering temperature cycling, mechanical shock, and HBM ESD testing. However, final suitability depends on system-level validation per ISO 16750 and vehicle-specific stress profiles.
How does the SOD123W package affect thermal performance compared to larger TVS packages?
The SOD123W package achieves Rth(j-sp) = 18 K/W to the cathode solder point - significantly lower than DO-214AC (e.g., SMAJ series, ~50 K/W) due to direct thermal path through the cathode tab. This enables higher surge repetition rates in confined spaces, provided the PCB copper pour under the cathode meets the 1 cm² recommendation.
Can PTVS14VS1UR,115 be used in bidirectional configurations?
No - it is strictly unidirectional. The device conducts only when cathode voltage exceeds anode voltage by ≥VBR. For bidirectional protection (e.g., data lines), two devices must be connected anode-to-anode or a dedicated bidirectional TVS like PTVS14VS1UR,115's counterpart in the PTVSxS1U series must be selected.
