Product details
Overview
PTVS8V0S1UTR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature transient overvoltage protection in power rails. It features VRWM = 8.0 V, VBR(min) = 8.89 V at 1 mA, VCL = 13.6 V at IPPM = 29.4 A (10/1000 µs), and operates up to Tj = 185 °C - enabling robust surge suppression in industrial power management and automotive under-hood circuits.
For engineers reviewing the PTVS8V0S1UTR,115 datasheet, PTVS8V0S1UTR,115 pinout, PTVS8V0S1UTR,115 application, or PTVS8V0S1UTR,115 equivalent, key selection criteria include clamping voltage at rated peak pulse current, thermal resistance to solder point (Rth(j-sp) = 18 K/W), junction temperature derating behavior, and cathode/anode polarity marking alignment with PCB layout.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped crowbar during transients: below VRWM = 8.0 V it exhibits <0.03 µA reverse leakage; above VBR(min) = 8.89 V it avalanches sharply to clamp at VCL = 13.6 V under 29.4 A (10/1000 µs). Its silicon junction is optimized for stable breakdown across −55 °C to +185 °C ambient.
The device uses a planar passivated junction structure with low thermal resistance (Rth(j-sp) = 18 K/W) and high ESD tolerance (30 kV contact discharge per IEC 61000-4-2), enabling reliable operation on compact PCBs without heatsinking in high-reliability power supply front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 8.0 V - maximum continuous reverse working voltage before significant leakage; defines safe operating margin for 12 V rail protection. |
| VBR (min) | 8.89 V at 1 mA - guaranteed avalanche initiation threshold; ensures predictable turn-on before system damage. |
| VCL | 13.6 V at IPPM = 29.4 A - clamped voltage during 400 W transient; must stay below IC absolute max ratings. |
| PPPM | 400 W - peak pulse power rating per IEC 61643-321 (10/1000 µs); confirms surge handling capability for ISO 7637-2 Pulse 1/2a. |
| Tj(max) | 185 °C - maximum junction temperature; supports placement near hot components (e.g., MOSFETs, inductors) without derating. |
| Rth(j-sp) | 18 K/W - thermal resistance from junction to cathode solder point; enables effective heat transfer to copper pour without thermal vias. |
| IRM | 0.03 µA at VRWM - ultra-low leakage preserves battery life and avoids false triggering in always-on circuits. |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body height; flat lead profile with cathode-marking bar; optimized for reflow and wave soldering per IPC-7351B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 12 V input); marking bar on package identifies this terminal; carries full surge current during clamping. |
| 2 (A) | Anode | Connected to ground reference; forms low-inductance return path; must be routed with minimal loop area to preserve clamping speed. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Rated for continuous operation at Tamb = 185 °C ambient - eliminates need for thermal derating in engine control units or industrial motor drives. |
| Low-profile packaging | 1.0 mm max height - enables use in space-constrained modules (e.g., DC-DC converter bricks, sensor nodes) without mechanical interference. |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2) - protects against human-handling events during assembly and field service without external shielding. |
| Stable clamping performance | VCL variation <±5 % over −55 °C to +150 °C - ensures consistent protection margin across automotive and industrial temperature ranges. |
| Low thermal resistance | Rth(j-sp) = 18 K/W - allows >90 % of transient energy to dissipate into PCB copper, reducing localized heating and improving reliability. |
Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | VRWM = 8.0 V, VCL = 13.6 V, PPPM = 400 W, but Tj(max) = 150 °C and Rth(j-a) = 70 K/W (free air) | Limited to lower-temperature environments; requires larger copper area for thermal management | Select when cost sensitivity outweighs high-temperature requirement and board space permits larger thermal pad |
| 1.5SMC8.0A | Same VRWM/VCL, but DO-214AB package (4.5 mm × 3.9 mm × 2.3 mm); PPPM = 1500 W, Tj(max) = 175 °C | Higher surge capacity but 2.3× larger footprint and 2.3× taller - unsuitable for ultra-thin modules | Choose for extreme surge immunity where PCB real estate and height allow, not for space-constrained designs |
Compared with SMAJ8.0A and 1.5SMC8.0A, PTVS8V0S1UTR,115 uniquely combines SOD123W's 1 mm height and 2.6 mm length with 185 °C junction rating and 18 K/W junction-to-solder-point thermal resistance - making it the only option for thermally dense, high-reliability 12 V rail protection where both miniaturization and under-hood temperature resilience are mandatory.

FAQ
What is the maximum clamping voltage of PTVS8V0S1UTR,115 under standard test conditions?
The clamping voltage VCL is 13.6 V at a peak pulse current IPPM of 29.4 A, measured using the 10/1000 µs waveform per IEC 61643-321. This value is guaranteed across the full operating temperature range (−55 °C to +150 °C), with typical variation less than ±4.5 %.
How does the thermal performance of PTVS8V0S1UTR,115 compare to standard SOD-123 TVS diodes?
PTVS8V0S1UTR,115 achieves Rth(j-sp) = 18 K/W - 3× better than typical SOD-123 TVS devices (≈50–60 K/W) - due to optimized cathode tab geometry and internal die attach. This enables direct heat transfer to the PCB solder joint, supporting sustained operation at 185 °C junction temperature without external heatsinking.
Can PTVS8V0S1UTR,115 be used in bidirectional configurations?
No - PTVS8V0S1UTR,115 is strictly unidirectional. Its anode-cathode construction provides low leakage (<0.03 µA) and sharp avalanche turn-on only in reverse bias. For bidirectional protection, two devices must be connected in series opposing configuration, or a dedicated bidirectional part like PTVS8V0S1UTR,115's counterpart PTVS8V0S1UTR,115-BI must be selected.
What is the significance of the 'C8' marking on the PTVS8V0S1UTR,115 package?
'C8' is the manufacturer's top-side marking code defined in Table 4 of the datasheet, uniquely identifying the PTVS8V0S1UTR variant (VRWM = 8.0 V) within the PTVSxS1UTR series. The bar adjacent to 'C8' indicates the cathode (Pin 1), providing unambiguous polarity orientation during automated optical inspection and pick-and-place assembly.
