Product details
Overview
PTVS6V5S1UTR,115 from Nexperia is a unidirectional 400 W transient voltage suppressor (TVS) diode in SOD123W (CFP3) package, designed for high-temperature overvoltage clamping in power rails. It features VRWM = 6.5 V, VBR(min) = 7.22 V at 5 mA, VCL = 11.2 V at IPPM = 35.7 A (10/1000 µs), and operates up to Tj = 185 °C - enabling robust protection in automotive engine control units and industrial motor drives.
For engineers reviewing the PTVS6V5S1UTR,115 datasheet, PTVS6V5S1UTR,115 pinout, PTVS6V5S1UTR,115 application, or PTVS6V5S1UTR,115 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD tolerance, thermal resistance under PCB copper constraints, peak pulse current handling at elevated junction temperature, and cathode-anode polarity alignment in series-connected protection schemes.
Technical Context
This unidirectional TVS operates as a reverse-biased avalanche clamp: it remains high-impedance below VRWM = 6.5 V, then rapidly breaks down at VBR = 7.22–7.98 V (min–max) to limit transients. Its IEC 61643-321-compliant 10/1000 µs waveform rating delivers 400 W peak pulse power with IPPM = 35.7 A.
Thermal design is critical: Rth(j-a) = 220 K/W on standard FR4, but drops to 18 K/W at the cathode solder point (Rth(j-sp)), supporting sustained operation at Tamb = –55 °C to +185 °C and Tj ≤ 185 °C - validated per IEC 60134 limiting values and high-temp reliability testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 6.5 V - maximum continuous reverse working voltage before leakage exceeds 5 µA; sets upper bound for protected rail voltage. |
| VBR (min) | 7.22 V at 5 mA - guaranteed avalanche initiation threshold; ensures clamping engages before downstream IC absolute max ratings are breached. |
| VCL | 11.2 V at IPPM = 35.7 A - clamped voltage during 10/1000 µs surge; must stay below protected device's IO or supply withstand level. |
| PPPM | 400 W - peak pulse power rating per IEC 61643-321; defines energy-handling capability for repetitive or single-event surges. |
| IRM | 250 µA max at VRWM - low leakage preserves system standby current budget in battery-powered applications. |
| Tj max | 185 °C - extended junction temperature rating enables placement near heat sources (e.g., power MOSFETs, DC-DC inductors) without derating. |
| Rth(j-sp) | 18 K/W - thermal resistance from junction to cathode solder point; guides minimum copper area and via count for thermal relief. |
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; avalanche conduction occurs from anode to cathode during overvoltage events. |
| 2 (A) | Anode | Connected to ground or low-impedance return path; establishes reference for clamping action and defines unidirectional polarity. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Tj ≤ 185 °C and Tamb ≤ 185 °C - eliminates need for thermal derating in under-hood or enclosed industrial enclosures. |
| Low-profile SMD package | 1.0 mm max height - enables use in space-constrained modules (e.g., automotive sensor nodes, portable test equipment). |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2), >8 kV HBM - provides system-level ESD immunity without additional discrete protection stages. |
| Precision clamping | VBR tolerance ±5.5% (7.22–7.98 V) and VCL = 11.2 V - tight parametric control simplifies margin analysis for 5 V or 6 V logic rails. |
| Low IRM | ≤250 µA at VRWM - minimizes quiescent power loss in always-on circuits such as CAN bus termination or MCU reset supervisors. |
Applications
| Automotive Engine Control Unit (ECU) | Industrial PLC Power Input Stage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.5A | Same VRWM (6.5 V) and unidirectional configuration, but rated PPPM = 400 W at 25 °C only; derates to ~220 W at 125 °C; Rth(j-a) = 50 K/W. | Limited to lower-temperature industrial controls; unsuitable for sustained >125 °C ambient or junction conditions. | Select when cost sensitivity outweighs high-temp requirement and thermal layout allows larger copper area. |
| 1.5SMC6.8A | Higher VRWM = 6.8 V, VCL = 11.5 V at 35.1 A, but SMC package (7.1 mm × 6.2 mm × 2.6 mm); Tj max = 175 °C; PPPM = 1500 W (but larger footprint). | Used where higher surge energy (>400 W) is needed and board space permits larger package; not drop-in compatible. | Choose for legacy designs requiring proven 1500 W surge rating and existing SMC footprints, accepting size and thermal trade-offs. |
Compared with SMAJ6.5A, PTVS6V5S1UTR,115 offers superior high-temperature stability (185 °C vs. 125 °C derated limit) and lower profile; versus 1.5SMC6.8A, it trades surge capacity for 60% smaller footprint and better thermal coupling in dense layouts - making it optimal for modern miniaturized, thermally aggressive systems.

FAQ
What is the maximum clamping voltage of PTVS6V5S1UTR,115 under a 10/1000 µs surge?
The clamping voltage VCL is 11.2 V at rated peak pulse current IPPM = 35.7 A, measured per IEC 61643-321 using the standardized 10/1000 µs current waveform. This value is guaranteed across the full operating temperature range and represents the maximum voltage seen by the protected circuit during surge conduction.
Can PTVS6V5S1UTR,115 be used in bidirectional configurations?
No - PTVS6V5S1UTR,115 is strictly unidirectional, with cathode (pin 1) and anode (pin 2) terminals defined in the datasheet. Bidirectional protection requires either two series-opposed unidirectional devices or a dedicated bidirectional TVS like PTVS6V5S2UTR; using this part in reverse bias beyond VRWM risks permanent damage.
How does the 185 °C junction temperature rating impact PCB layout?
The 185 °C Tj rating enables placement near heat sources, but thermal management remains critical: the 18 K/W Rth(j-sp) value requires direct cathode connection to ≥1 cm² of 1 oz copper with ≥2 thermal vias to internal ground planes to sustain continuous high-temp operation without exceeding limits.
Is the marking code 'C5' sufficient to identify PTVS6V5S1UTR,115 on the device body?
Yes - per Table 4 of the datasheet, 'C5' is the official marking code for PTVS6V5S1UTR,115 on the SOD123W package. The bar adjacent to the marking denotes the cathode (pin 1), providing unambiguous polarity identification during visual inspection and automated optical recognition (AOI) in SMT lines.
