Product details
Overview
PTVS6V5S1UTR-Q from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature transient overvoltage protection in automotive power rails. It features VRWM = 6.5 V, VBR(min) = 7.22 V at 10 mA, clamping voltage VCL = 11.2 V at IPPM = 35.7 A (10/1000 µs), and operates up to Tj = 185 °C.
For engineers reviewing the PTVS6V5S1UTR-Q datasheet, PTVS6V5S1UTR-Q pinout, PTVS6V5S1UTR-Q application, or PTVS6V5S1UTR-Q equivalent, this device is selected for robust ESD/ISO 7637-2 surge suppression in engine control units, battery management systems, and 12 V automotive subsystems requiring AEC-Q101 qualification and low-profile surface-mount integration.
Technical Context
This unidirectional TVS diode operates as a clamping device in reverse-biased configuration, triggering at breakdown voltage ≥7.22 V and limiting transients to ≤11.2 V at 35.7 A peak pulse current. Its junction-to-solder-point thermal resistance is 18 K/W, enabling stable operation under sustained high-temperature ambient conditions up to +185 °C.
The device complies with IEC 61643-321 (10/1000 µs waveform) and achieves 30 kV contact ESD immunity per IEC 61000-4-2. Its cathode-anode polarity is marked by a bar on the SOD123W body, and it supports non-repetitive forward surge current up to 50 A (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 6.5 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin in 12 V automotive circuits. |
| VBR (min) | 7.22 V at 10 mA - Guaranteed minimum breakdown voltage ensures reliable turn-on above system nominal voltage. |
| VCL | 11.2 V at IPPM = 35.7 A - Clamped voltage during 10/1000 µs surge; protects downstream ICs rated ≤12 V. |
| PPPM | 400 W - Peak pulse power handling capability per IEC 61643-321; enables suppression of ISO 7637-2 Pulse 1/2a/5a surges. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.5A-Q | Lower PPPM (400 W same), but higher VCL = 11.5 V at 38.2 A; 1.5 mm height vs. 1.0 mm. | Less suitable for ultra-low-profile ADAS camera modules due to taller SMA package. | Select when existing SMA footprint reuse is prioritized over height constraint. |
| TPSMF6.5A | Same SOD123W package, but lower PPPM = 200 W; VCL = 11.7 V at 17 A; not AEC-Q101 qualified. | Not approved for automotive powertrain use; limited to infotainment or non-safety-critical subsystems. | Select only for cost-sensitive industrial applications where AEC-Q101 is not required. |
Compared with SMAJ6.5A-Q and TPSMF6.5A, PTVS6V5S1UTR-Q uniquely combines AEC-Q101 qualification, 1.0 mm profile, and guaranteed 400 W surge capacity at 6.5 V standoff-making it the only option meeting full automotive under-hood requirements without package or rating compromise.

FAQ
What is the maximum clamping voltage of PTVS6V5S1UTR-Q during a 10/1000 µs surge?
The clamping voltage VCL is 11.2 V at peak pulse current IPPM = 35.7 A under IEC 61643-321 10/1000 µs waveform conditions. This value is measured at Tj = 25 °C and represents the maximum voltage seen by downstream circuitry during standardized surge testing.
Is PTVS6V5S1UTR-Q suitable for 24 V commercial vehicle applications?
No-it is specified for VRWM = 6.5 V and intended for 12 V automotive systems. For 24 V applications, Nexperia offers PTVS24VS1UTR-Q (VRWM = 24 V, VCL = 38.9 V), which shares the same SOD123W package, AEC-Q101 qualification, and 400 W rating.
How does the thermal resistance Rth(j-sp) impact PCB layout for high-surge environments?
With Rth(j-sp) = 18 K/W, optimal thermal performance requires direct copper connection from the cathode pad to a ≥1 cm² internal or external ground plane. The datasheet specifies this value assumes soldering to a standard FR4 board with tin-plated cathode pad-reducing pad size or omitting thermal vias increases junction temperature and risks derating.
Does PTVS6V5S1UTR-Q require orientation-specific mounting on the PCB?
Yes-the cathode (pin 1) is marked by a bar on the SOD123W body and must be connected to the protected line (e.g., 12 V rail), while the anode (pin 2) connects to ground. Incorrect orientation results in forward conduction during normal operation and catastrophic failure under surge conditions.
