Product details
Overview
PTVS7V5S1UR,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 = 7.5 V, VBR(min) = 8.33 V at IR = 1 mA, VCL(max) = 12.9 V at IPPM = 31.0 A (10/1000 µs), and IRM ≤ 0.2 µA - enabling robust protection of 5 V–12 V logic and power supply inputs in industrial control modules.
For engineers reviewing the PTVS7V5S1UR,115 datasheet, PTVS7V5S1UR,115 pinout, PTVS7V5S1UR,115 application, or PTVS7V5S1UR,115 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD max, peak pulse current capability under IEC 61643-321 10/1000 µs waveform, thermal resistance to PCB (Rth(j-sp) = 18 K/W), and AEC-Q101 qualification status per revision history.
Technical Context
This unidirectional TVS operates as a reverse-biased avalanche diode, triggering when transient voltage exceeds its breakdown threshold (VBR = 8.33–9.21 V). Its low clamping voltage (12.9 V max) ensures downstream 12 V-rated components remain within safe operating limits during surge events.
Rated for 400 W peak pulse power (IEC 61643-321, 10/1000 µs), it delivers IPPM = 31.0 A while maintaining junction temperature below 150 °C. The SOD123W package supports high-density layout with 1 mm height and thermal resistance Rth(j-a) = 220 K/W (FR4, single-sided copper).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 7.5 V - maximum continuous reverse working voltage before leakage rises significantly; sets upper limit for protected rail voltage. |
| VBR (min) | 8.33 V at IR = 1 mA - guaranteed avalanche onset voltage; ensures reliable turn-on above normal operating voltage. |
| VCL (max) | 12.9 V at IPPM = 31.0 A - peak clamped voltage during 10/1000 µs surge; must stay below absolute max rating of downstream ICs. |
| PPPM | 400 W - rated peak pulse power handling per IEC 61643-321; defines surge energy absorption capacity. |
| IRM | ≤ 0.2 µA at VRWM - ultra-low reverse leakage; minimizes quiescent power loss in battery-powered systems. |
| Rth(j-sp) | 18 K/W - thermal resistance from junction to solder point; enables effective heat transfer to PCB copper pour. |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2); provides system-level ESD immunity without additional protection stages. |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat leads, cathode marked by bar. Optimized for automated placement and reflow soldering with standard footprint (2.1 mm × 1.4 mm pad, 0.1 mm stencil thickness recommended).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., +5 V rail); marking bar identifies this terminal; carries surge current into ground path. |
| 2 | Anode (A) | Connected to circuit ground; completes conduction path during transient; low-inductance layout critical for clamping speed. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Qualified per revision v.4 (Dec 2025); supports use in automotive ECUs where reliability under thermal cycling and vibration is mandatory. |
| Low-profile SOD123W | 1.0 mm max height; enables thin-form-factor designs in space-constrained modules such as motor drivers and sensor nodes. |
| High IPPM capability | 31.0 A peak pulse current; sustains 400 W surges without degradation, suitable for load-dump and ISO 7637-2 pulse 5a scenarios. |
| Ultra-low IRM | ≤ 0.2 µA at 7.5 V; eliminates measurable standby current drain in always-on 5 V monitoring circuits. |
| Robust ESD immunity | 30 kV contact discharge rating; eliminates need for secondary ESD protection on board-level interfaces. |
Applications
| Industrial Power Input Protection | PLC Digital I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | DO-214AC package; VRWM = 7.5 V; VCL = 12.0 V @ 32.5 A; PPPM = 400 W; Rth(j-a) ≈ 50 K/W higher than SOD123W. | Larger footprint (4.5 mm × 2.7 mm) and 2.2 mm height limit use in ultra-thin assemblies. | Select when higher surge repetition rate is needed and board space allows larger package. |
| 1.5SMC7.5A | DO-214AB package; VRWM = 7.5 V; VCL = 12.9 V @ 31.0 A; PPPM = 1500 W; 3× higher power but 5.3 mm × 2.8 mm size and 2.5 mm height. | Over-specified for 400 W needs; introduces unnecessary thermal mass and layout area in compact designs. | Choose only if legacy design uses DO-214AB or future-proofing for >1 kV surge events is required. |
Compared with SMAJ7.5A and 1.5SMC7.5A, PTVS7V5S1UR,115 offers identical electrical protection performance in a 60% smaller footprint and 55% lower profile - making it optimal for modern space- and height-constrained industrial and automotive modules where thermal coupling to PCB is prioritized.

FAQ
Is PTVS7V5S1UR,115 AEC-Q101 qualified?
Yes - according to Revision v.4 (December 2025) of the official Nexperia datasheet, PTVS7V5S1UR,115 is explicitly listed among the 33 types upgraded to standard AEC-Q101 qualification. This confirms its suitability for automotive electronic control units, including body electronics and infotainment power supplies.
What is the maximum clamping voltage at rated peak pulse current?
The maximum clamping voltage (VCL) for PTVS7V5S1UR,115 is 12.9 V at IPPM = 31.0 A under IEC 61643-321 10/1000 µs waveform conditions. This value is measured at Tj = 25 °C and guarantees that protected downstream components will not see voltage exceeding 12.9 V during specified surge events.
Can PTVS7V5S1UR,115 be used in bidirectional configurations?
No - PTVS7V5S1UR,115 is a unidirectional TVS diode with anode and cathode terminals. It conducts only when reverse-biased beyond VBR. For bidirectional protection (e.g., data lines), a separate symmetric device like PTVS7V5S1UTR or dual-diode array is required.
How does thermal resistance affect PCB layout for this TVS?
With Rth(j-sp) = 18 K/W, optimal thermal performance requires direct copper connection from the cathode pad to a large internal or external ground plane. The datasheet recommends a 1 cm² mounting pad for cathode on FR4; reducing pad area increases junction temperature rise during repeated surges and may degrade long-term reliability.
