Product details
Overview
PTVS7V5S1UTR-QX from Nexperia is a unidirectional 400 W transient voltage suppressor (TVS) diode in SOD123W (CFP3) package, designed for high-temperature automotive and industrial power rail protection. It features 7.5 V reverse standoff voltage (VRWM), 8.77 V typical breakdown voltage (VBR), 12.9 V clamping voltage (VCL) at 31.0 A peak pulse current (IPPM), and operates up to 185 °C junction temperature.
For engineers reviewing the PTVS7V5S1UTR-QX datasheet, PTVS7V5S1UTR-QX pinout, PTVS7V5S1UTR-QX application, or PTVS7V5S1UTR-QX equivalent, this device serves as a robust overvoltage clamp for 12 V automotive subsystems, battery management inputs, and high-reliability DC power interfaces where thermal stability and AEC-Q101 qualification are mandatory.
Technical Context
This TVS diode operates in avalanche mode during transients, with unidirectional polarity enabling forward conduction only from anode to cathode. Its low 0.2 µA reverse leakage at VRWM ensures minimal standby power loss in always-on circuits.
The device uses a planar silicon junction optimized for stable clamping across –55 °C to +185 °C ambient, with thermal resistance from junction to solder point as low as 18 K/W - critical for sustained surge handling in confined PCB layouts without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 7.5 V - Maximum continuous reverse operating voltage before clamping begins; matches nominal 12 V system rails with margin. |
| VBR (typ) | 8.77 V - Breakdown initiates at this voltage under 1 mA test current; defines onset of protective clamping action. |
| VCL @ IPPM | 12.9 V - Clamped voltage at 31.0 A peak pulse (10/1000 µs); limits downstream IC stress during ISO 7637-2 pulses. |
| PPPM | 400 W - Peak pulse power rating per IEC 61643-321; enables suppression of high-energy load-dump transients. |
| Tj max | 185 °C - Maximum junction temperature; supports under-hood automotive placement without derating. |
| IRM | 0.2 µA - Reverse leakage at VRWM; ensures negligible quiescent current in battery-sensitive applications. |
| AEC-Q101 | Qualified - Meets stress-test requirements for discrete semiconductors in automotive electronics. |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body height, flat leads, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected circuit's positive rail; absorbs transient energy into ground path when voltage exceeds VBR. |
| 2 (A) | Anode | Connected to system ground; completes clamping path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction rated to 185 °C - eliminates thermal derating in engine control units and ADAS modules. |
| Low-profile SMD package | 1.0 mm max height - enables placement beneath connectors or in space-constrained ECU modules. |
| AEC-Q101 qualification | Stress-tested per automotive standard - reduces validation effort for Tier 1 suppliers. |
| Low clamping ratio | VCL/VBR = 1.47 - tight voltage control minimizes overdesign of downstream TVS cascades or regulator input ratings. |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2) - protects against assembly-line and field-handling ESD events. |
Applications
| Automotive Power Distribution | Industrial Sensor Interface |
|---|---|
Use Scenario: Protection of 12 V supply lines feeding body control modules (BCM), lighting drivers, or infotainment head units against ISO 7637-2 load dump and jump-start surges. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed upstream of DC-DC converters and LDOs to limit transient voltage before regulation. Use Value: Maintains VCL ≤ 12.9 V during 31 A transients, preventing latch-up or damage to 16 V-rated input regulators. | Use Scenario: Guarding analog sensor inputs (e.g., pressure, temperature) in factory automation PLCs exposed to inductive switching noise and relay coil flyback. IC Role / Device Role / Timing Role: Fast-response overvoltage limiter on signal lines referenced to local ground, shunting spikes before op-amp front-ends. Use Value: Sub-100 ns response time and 0.2 µA leakage preserve signal integrity and minimize offset drift in precision measurement paths. |
| On-Board Charger Input Stage | High-Temperature Motor Control |
Use Scenario: Input-stage surge protection for AC/DC converters in EV on-board chargers operating near power electronics with elevated ambient temperatures. IC Role / Device Role / Timing Role: Primary clamping device on the DC bus prior to PFC stage, absorbing line-side transients induced by grid switching. Use Value: Stable 400 W PPPM performance up to 185 °C junction temperature avoids thermal runaway during repeated surge events. | Use Scenario: Protection of gate driver supply rails in traction inverter half-bridges subjected to high dv/dt coupling and thermal cycling. IC Role / Device Role / Timing Role: Localized rail clamp adjacent to isolated gate drivers, suppressing coupled transients from IGBT switching. Use Value: 18 K/W Rth(j-sp) enables direct thermal coupling to copper pour, sustaining clamping capability during 10+ second thermal soak at 150 °C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A-Q | Lower PPPM (400 W same), but higher VCL (12.0 V typ) and larger SMA package (2.5 mm height). | Not AEC-Q101 qualified; limited to industrial use where automotive reliability not required. | Select when cost sensitivity outweighs height constraint and AEC compliance is unnecessary. |
| PTVS7V5S1UR | Same electrical specs but non-automotive grade (no AEC-Q101); identical SOD123W footprint. | Lacks automotive qualification documentation and extended temperature screening. | Choose for non-automotive prototypes or cost-optimized consumer designs where full AEC traceability is not mandated. |
Compared with SMAJ7.5A-Q and PTVS7V5S1UR, the PTVS7V5S1UTR-QX delivers verified AEC-Q101 compliance, 1 mm profile, and guaranteed 185 °C operation - making it the sole choice for production automotive ECUs requiring zero derating in under-hood environments.

FAQ
What is the maximum clamping voltage of PTVS7V5S1UTR-QX under a 10/1000 µs surge?
The clamping voltage (VCL) is 12.9 V at 31.0 A peak pulse current (IPPM), measured per IEC 61643-321. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuits during standardized surge events.
Does PTVS7V5S1UTR-QX support bidirectional transient suppression?
No - it is a unidirectional TVS diode with anode and cathode terminals. It conducts only when the cathode is more positive than the anode by ≥ VBR. For bidirectional protection, two devices must be used in series opposition or a dedicated bidirectional part selected.
How does the 185 °C junction rating impact PCB layout decisions?
The 185 °C Tj max allows uninterrupted operation at 150 °C ambient without power derating, provided thermal resistance to solder point (Rth(j-sp) = 18 K/W) is maintained via adequate copper pour on the cathode pad. No thermal vias or external heatsinks are required for typical automotive duty cycles.
Is the marking code 'C7' sufficient for field verification of PTVS7V5S1UTR-QX?
Yes - per Nexperia's marking table, 'C7' is the unique top-side laser mark for PTVS7V5S1UTR-QX. The bar adjacent to pin 1 identifies the cathode, confirming correct orientation during automated optical inspection (AOI) and manual rework.
