Product details
Overview
PTVS6V5S1UR,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 = 6.5 V, VBR(min) = 7.22 V at IR = 10 mA, VCL(max) = 11.2 V at IPPM = 35.7 A (10/1000 µs), and IRM ≤ 5 µA - deployed in industrial power supply input protection where fast response and low clamping voltage are critical.
For engineers reviewing the PTVS6V5S1UR,115 datasheet, PTVS6V5S1UR,115 pinout, PTVS6V5S1UR,115 application, or PTVS6V5S1UR,115 equivalent, this device is selected for robust 6.5 V rail protection requiring sub-1 mm profile, AEC-Q101 qualification (per revision v.4), and verified IEC 61643-321 compliance with 10/1000 µs waveform handling.
Technical Context
This unidirectional TVS operates as a clamping diode: reverse-biased under normal conditions (VRWM = 6.5 V), it avalanches sharply at VBR ≥ 7.22 V to divert surge current away from downstream circuitry. Its junction-to-solder-point thermal resistance is 18 K/W, enabling effective heat dissipation during repetitive transients.
The device conforms to IEC 61643-321 with a rated peak pulse power PPPM = 400 W (10/1000 µs), supports non-repetitive forward surge up to 50 A (8.3 ms half-sine), and maintains IRM ≤ 5 µA at VRWM - ensuring minimal leakage in always-on power monitoring circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 6.5 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min) | 7.22 V at 10 mA - guaranteed avalanche initiation threshold for reliable overvoltage detection |
| VCL (max) | 11.2 V at IPPM = 35.7 A - peak clamped voltage limiting stress on protected ICs |
| PPPM | 400 W - surge energy handling capacity per IEC 61643-321 (10/1000 µs waveform) |
| IRM | ≤ 5 µA - low reverse leakage preserving efficiency in battery-backed or low-power systems |
| Package | SOD123W (CFP3) - 2.6 × 1.7 × 1.0 mm surface-mount footprint with 1 mm height for space-constrained PCBs |
| AEC-Q101 | Qualified - validated for automotive-grade reliability per revision v.4 (20251201) |
Pinout & Package

| 2 (A) | Anode | Connected to ground reference; completes clamping path during transient events |
Key Features
| Feature | Design Value |
|---|---|
| Peak pulse power rating | 400 W - sustains high-energy surges without degradation in industrial 24 VDC systems |
| Low clamping voltage | VCL = 11.2 V - limits voltage overshoot to safe levels for 5 V–12 V logic and PMIC inputs |
| Ultra-low profile | 1.0 mm max height - enables placement under connectors or in tight board-to-board interfaces |
| AEC-Q101 qualified | Validated per revision v.4 - supports deployment in automotive body control modules and infotainment power rails |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2) - withstands handling and system-level ESD events |
Applications
| Industrial Power Supply Input Protection | Automotive Body Control Module (BCM) Power Rail |
|---|---|
Use Scenario: 24 VDC industrial PLC power input subjected to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between input rail and ground to limit voltage excursions below 12 V. Use Value: Prevents damage to upstream DC-DC converters and downstream microcontrollers by clamping to 11.2 V at 35.7 A surge current. |
Use Scenario: 12 V battery-fed BCM power domain exposed to ISO 7637-2 Pulse 1/2a/5a transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main 12 V supply line, positioned before LDO regulators. Use Value: Maintains system uptime by suppressing >100 V spikes to ≤11.2 V within nanoseconds, leveraging AEC-Q101 qualification. |
| Smart Sensor Node Power Conditioning | POS Terminal 5 V USB-C Power Input |
Use Scenario: Battery-powered environmental sensor node with integrated 3.3 V MCU and analog front-end. IC Role / Device Role / Timing Role: Secondary protection on regulated 3.3 V rail against ESD and coupling-induced transients. Use Value: Low IRM (≤5 µA) avoids battery drain; 1 mm height allows co-location with small-area sensors. |
Use Scenario: Point-of-sale terminal with USB-C PD input delivering 5 V ±5 % to internal logic. IC Role / Device Role / Timing Role: Input-side TVS on 5 V bus to absorb hot-plug and cable discharge events. Use Value: Clamps to 11.2 V while maintaining VRWM = 6.5 V margin above nominal 5 V, preventing false triggering. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.5A | Same VRWM (6.5 V), but SMA package (4.5 × 2.7 × 2.2 mm); PPPM = 400 W; VCL = 11.2 V; IRM = 500 µA | Larger footprint and higher leakage reduce suitability for space-constrained or ultra-low-power designs | Select when legacy SMA layout exists and height >1 mm is acceptable |
| 1.5SMC6.8A | Higher VRWM (6.8 V), DO-214AB package (7.1 × 6.2 × 2.3 mm); PPPM = 1500 W; VCL = 10.5 V; IRM = 1000 µA | Over-spec'd power rating and excessive size for 6.5 V rail protection; not AEC-Q101 qualified | Use only if 1500 W surge margin is mandatory and board space permits large package |
Compared with SMAJ6.5A and 1.5SMC6.8A, PTVS6V5S1UR,115 delivers identical clamping performance in a 60 % smaller footprint, 100× lower leakage, and automotive-qualified reliability - making it optimal for modern compact, low-power, and automotive-adjacent designs.

FAQ
What is the maximum clamping voltage of PTVS6V5S1UR,115 under standard test conditions?
The maximum clamping voltage VCL is 11.2 V at IPPM = 35.7 A, measured with an 8/20 µs current waveform per IEC 61643-321. This value ensures protected downstream ICs experience no more than 11.2 V during worst-case surge events, preserving functional safety margins for 5 V and 12 V logic domains.
Is PTVS6V5S1UR,115 qualified for automotive use?
Yes - per revision v.4 (issued 1 December 2025), PTVS6V5S1UR,115 is explicitly listed among the 33 types upgraded to AEC-Q101 qualification. This validation covers temperature cycling, humidity testing, and surge endurance required for under-hood and cabin electronics applications.
How does the SOD123W package affect thermal performance?
The SOD123W package achieves Rth(j-sp) = 18 K/W to the cathode solder point, enabling efficient heat transfer into the PCB copper. When mounted on FR4 with a 1 cm² cathode pad, its Rth(j-a) drops to 130 K/W - sufficient for intermittent 400 W pulses without derating in typical industrial ambient conditions (−40 °C to +85 °C).
Can PTVS6V5S1UR,115 replace PTVS6V0S1UR in existing designs?
Yes - both share identical SOD123W package, pinout, and thermal characteristics. The VRWM increases from 6.0 V to 6.5 V, raising the standoff margin without affecting clamping behavior (VCL remains 11.2 V). Designers should verify that the higher VRWM does not compromise sensitivity in low-voltage fault-detection circuits.
