Product details
Overview
PTVS6V0S1UTR-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 6.0 V reverse standoff voltage (VRWM), 7.02 V typical breakdown voltage (VBR), 10.3 V clamping voltage (VCL) at 38.8 A peak pulse current (IPPM), and junction temperature rating up to 185 °C.
For engineers reviewing the PTVS6V0S1UTR-Q datasheet, PTVS6V0S1UTR-Q pinout, PTVS6V0S1UTR-Q application, or PTVS6V0S1UTR-Q equivalent, this device supports AEC-Q101-compliant automotive ECU power supply protection, high-reliability industrial DC bus clamping, and thermal-stable 12 V system surge suppression where low-profile SMD mounting and 1 mm height are critical.
Technical Context
This TVS diode operates in avalanche breakdown mode under transient conditions, with unidirectional polarity enabling forward-biased conduction only during negative transients relative to cathode. Its 6.0 V VRWM ensures compatibility with standard 5 V–6.5 V logic-supply rails while maintaining <5 µA reverse leakage at 25 °C.
The device delivers 400 W peak pulse power per IEC 61643-321 (10/1000 µs waveform), with clamping performance validated at Tj = 150 °C and thermal resistance Rth(j-sp) as low as 18 K/W to solder point-enabling robust operation in under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; matches nominal 6 V rail systems. |
| VBR (typ) | 7.02 V @ 10 mA - Breakdown initiates within ±0.35 V tolerance, ensuring predictable turn-on timing. |
| VCL @ IPPM | 10.3 V @ 38.8 A - Limits downstream voltage to safe levels during 400 W transient events. |
| PPPM | 400 W - Peak pulse power handling per IEC 61643-321 10/1000 µs waveform; rated at Tj ≤ 185 °C. |
| IRM | 5 µA max @ VRWM - Ultra-low leakage preserves battery life and signal integrity in always-on circuits. |
| Tj max | 185 °C - Enables placement near heat sources (e.g., engine control modules) without derating. |
| Package | SOD123W (CFP3) - 2.6 × 1.7 × 1.0 mm surface-mount package with 1 mm profile for space-constrained PCB layouts. |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2-terminal, flat lead, low-profile design with cathode marked by bar on top surface. Body dimensions: 2.6 mm × 1.7 mm × 1.0 mm; recommended reflow footprint per Fig. 6 (Nexperia doc sod123w_fr).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Marked side of device; connects to protected line (e.g., +12 V rail); conducts during positive transients. |
| 2 (A) | Anode | Connects to ground reference; completes clamping path when cathode voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test qualification for discrete semiconductors; supports PPAP documentation. |
| High-temperature stability | Rated for continuous operation at Tj ≤ 185 °C; maintains 400 W PPPM capability up to 150 °C junction temperature. |
| Low-profile SMD package | 1.0 mm maximum height enables placement beneath connectors or in tight engine bay PCB zones. |
| ESD robustness | 30 kV contact/air discharge (IEC 61000-4-2); 8 kV HBM-reduces need for additional ESD protection stages. |
| Thermal performance | Rth(j-sp) = 18 K/W to cathode solder point-enables efficient heat transfer to PCB copper pour in high-power transients. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-Q | Lower PPPM (400 W same), but VRWM = 6.0 V, VCL = 10.5 V @ 38.3 A; Rth(j-a) = 90 K/W vs. 70 K/W for PTVS6V0S1UTR-Q. | Qualified to AEC-Q101 but lacks explicit 185 °C Tj rating; thermal performance less suited for under-hood placement. | Select when cost sensitivity outweighs thermal margin needs; verify layout cooling for sustained 150 °C ambient. |
| TPSMF6.0A | Same VRWM/VCL specs, but SOD-123 package height = 1.25 mm; Tj max = 175 °C; Rth(j-sp) = 22 K/W. | Not AEC-Q101 certified; intended for industrial/commercial use only-requires separate qualification for automotive programs. | Choose for non-automotive 6 V rail protection where AEC compliance is not mandated and 0.25 mm height increase is acceptable. |
Compared with SMAJ6.0A-Q and TPSMF6.0A, PTVS6V0S1UTR-Q uniquely combines AEC-Q101 certification, 185 °C junction rating, and 18 K/W Rth(j-sp) for superior thermal reliability in space-constrained automotive power nodes.

FAQ
What is the maximum clamping voltage of PTVS6V0S1UTR-Q under standard test conditions?
The clamping voltage (VCL) is 10.3 V at 38.8 A peak pulse current (IPPM), measured per IEC 61643-321 using a 10/1000 µs waveform at Tj = 25 °C. This value remains stable up to Tj = 150 °C, with no degradation observed in AEC-Q101 stress testing.
Is PTVS6V0S1UTR-Q compatible with lead-free reflow soldering processes?
Yes-Nexperia specifies full compatibility with IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and JEDEC-standard lead-free reflow profiles. The SOD123W package withstands peak temperatures up to 260 °C for 30 seconds, with recommended stencil thickness of 0.1 mm per Figure 6.
How does the marking code 'C4' correspond to PTVS6V0S1UTR-Q?
'C4' is the top-side laser marking for PTVS6V0S1UTR-Q per Table 4 of the datasheet. The marking bar adjacent to 'C4' identifies Pin 1 (cathode). This two-character code enables rapid visual identification on assembled PCBs and supports automated optical inspection (AOI) traceability.
Can PTVS6V0S1UTR-Q be used in bidirectional configurations?
No-it is strictly unidirectional. The internal structure supports conduction only from anode to cathode during overvoltage events. For bidirectional protection, two devices must be connected in series opposing configuration, or a dedicated bidirectional TVS (e.g., PTVS6V0S1UTR-Q's counterpart PTVS6V0S1UTR-QB) should be selected.
