Product details
Overview
PTVS7V5S1UTR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature transient overvoltage protection in power rails. It features VRWM = 7.5 V, VBR(min) = 8.33 V at 1 mA, VCL = 12.9 V at IPPM = 31.0 A (10/1000 µs), and operates up to Tj = 185 °C - enabling robust surge suppression in industrial power management systems.
For engineers reviewing the PTVS7V5S1UTR,115 datasheet, PTVS7V5S1UTR,115 pinout, PTVS7V5S1UTR,115 application, or PTVS7V5S1UTR,115 equivalent, key selection criteria include clamping voltage under 13 V at 31 A, thermal resistance as low as 18 K/W to solder point, reverse leakage ≤ 0.2 µA at VRWM, and compatibility with reflow/wave soldering footprints per SOD123W standard.
Technical Context
This TVS diode uses a planar silicon junction structure optimized for fast response (< 1 ns) to ESD and lightning-induced transients per IEC 61643-321 (10/1000 µs). Its unidirectional configuration provides forward conduction only during negative surges relative to cathode, requiring correct polarity placement on DC supply lines.
Thermal design is enabled by low Rth(j-sp) = 18 K/W (to cathode solder point) and stable breakdown voltage temperature coefficient of +5.0 mV/K, ensuring predictable clamping behavior across −55 °C to +185 °C ambient operation without derating below 400 W peak pulse power until Tj > 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 7.5 V - maximum continuous reverse operating voltage before clamping begins; sets minimum system rail margin |
| VBR (min) | 8.33 V at 1 mA - guaranteed breakdown initiation threshold; ensures reliable turn-on before downstream IC damage |
| VCL | 12.9 V at IPPM = 31.0 A - clamped voltage during full-rated surge; defines protected circuit's maximum transient exposure |
| PPPM | 400 W - peak pulse power handling per 10/1000 µs waveform; enables protection against IEC 61000-4-5 Level 4 surges |
| IRM | 0.2 µA at VRWM - ultra-low leakage preserves battery life and avoids false triggering in low-power standby modes |
| Tj max | 185 °C - extended junction temperature rating allows use in engine control units, motor drives, and enclosed industrial enclosures |
| Rth(j-sp) | 18 K/W - thermal resistance to cathode solder point; enables effective PCB copper pour heat sinking without external heatsink |
Pinout & Package
The PTVS7V5S1UTR,115 is housed in a SOD123W (CFP3) surface-mount plastic package measuring 2.6 mm × 1.7 mm × 1.0 mm with flat leads and 0.9–1.1 mm body height. The cathode is marked by a visible bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to system ground or lower-potential rail; marking bar aligns with this pin; carries full surge current during clamping |
| 2 (A) | Anode | Connected to protected line (e.g., 12 V input); reverse-biased during normal operation; forward-conducts only during negative transients |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction rated to 185 °C - eliminates thermal derating in automotive under-hood and industrial motor drive environments |
| Low-profile SMD package | 1.0 mm max height - enables use in space-constrained power modules and stacked PCB assemblies |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2) - protects against human-body and assembly-line electrostatic events without external shielding |
| Precision clamping | VCL/VBR ratio = 1.54 - tight voltage overhead ensures minimal headroom loss while maintaining safe margin for downstream 12 V logic |
| Thermal interface efficiency | Rth(j-sp) = 18 K/W - direct thermal path to PCB copper enables >90% of rated PPPM dissipation without thermal vias |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | VRWM = 7.5 V, VCL = 12.0 V at 34.4 A, but rated PPPM = 400 W only at 25 °C; derates to ~220 W at 125 °C junction | Lower thermal stability: max Tj = 150 °C limits use in high-ambient industrial enclosures | Select when cost sensitivity outweighs high-temperature requirement and board-level thermal management is sufficient |
| 1.5SMC7.5A | Same VRWM/VCL specs but in larger SMC (DO-214AB) package (4.5 mm × 3.9 mm × 2.3 mm); Rth(j-a) = 15 K/W vs. 70 K/W for PTVS7V5S1UTR | Requires 3× PCB area; better natural convection cooling but incompatible with ultra-thin designs | Choose for legacy footprint compatibility or where manual rework access is prioritized over size constraints |
Compared with SMAJ7.5A and 1.5SMC7.5A, PTVS7V5S1UTR,115 uniquely combines SOD123W miniaturization, 185 °C junction rating, and stable 400 W pulse power across full temperature range - making it optimal for next-gen compact, thermally aggressive embedded power systems.

FAQ
What is the maximum clamping voltage of PTVS7V5S1UTR,115 under full-rated surge current?
The clamping voltage VCL is 12.9 V at IPPM = 31.0 A using the standardized 10/1000 µs current waveform per IEC 61643-321. This value is measured at Tj = 25 °C and remains stable up to 150 °C junction temperature, with no degradation beyond ±0.5 V across the full operating range.
Can PTVS7V5S1UTR,115 be used in bidirectional protection configurations?
No - PTVS7V5S1UTR,115 is strictly unidirectional. Its anode-cathode construction only clamps positive transients on the anode side relative to cathode. For bidirectional protection, two devices must be connected in series opposition, or a dedicated bidirectional TVS such as PTVS7V5S2UTR should be selected.
Does the SOD123W package support automated optical inspection (AOI) after reflow?
Yes - the SOD123W outline (CFP3) has defined solder joint geometry and coplanar flat leads compatible with standard AOI systems. The 1.0 mm profile and 0.9–1.1 mm body height allow reliable shadow-free imaging, and the cathode marking bar provides unambiguous polarity verification during post-reflow inspection.
How does the 30 kV ESD rating translate to real-world board-level robustness?
The 30 kV contact discharge rating (IEC 61000-4-2) means the device can absorb ten non-repetitive ESD pulses at that level without parameter shift or failure. In practice, this exceeds typical board-level ESD threats (e.g., 8–15 kV human-body model), providing ≥2× safety margin for field reliability in handheld and panel-mounted industrial equipment.
