Product details
Overview
PTVS8V5P1UP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-energy ESD and surge protection on DC power rails. It features VRWM = 8.5 V, VBR(min) = 9.44 V at 1 mA, clamping voltage VCL = 14.4 V at IPPM = 41.7 A (10/1000 µs), and IRM ≤ 0.01 µA - enabling robust overvoltage suppression in automotive body control modules and industrial power supplies.
For engineers reviewing the PTVS8V5P1UP,115 datasheet, PTVS8V5P1UP,115 pinout, PTVS8V5P1UP,115 application, or PTVS8V5P1UP,115 equivalent, key selection criteria include clamping performance under IEC 61643-321 10/1000 µs waveform, thermal resistance to solder point (Rth(j-sp) = 12 K/W), AEC-Q101 qualification status per revision history, and compatibility with 1 mm profile PCB layouts.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VRWM (8.5 V), it avalanches at VBR ≥ 9.44 V and limits transient energy by diverting up to 41.7 A peak pulse current while maintaining VCL ≤ 14.4 V. Its junction-to-solder-point thermal resistance of 12 K/W enables effective heat dissipation during repetitive surges.
The device complies with IEC 61643-321 (10/1000 µs waveform) and achieves 30 kV contact ESD immunity per IEC 61000-4-2. Its SOD128 package supports surface-mount reflow with 3.8 mm × 2.6 mm footprint and 1 mm height - optimized for space-constrained automotive and industrial PCBs where low-profile protection is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W - sustains single 10/1000 µs transients without degradation, meeting IEC 61643-321 Class II requirements. |
| Reverse Standoff Voltage (VRWM) | 8.5 V - maximum continuous DC operating voltage before significant leakage; ensures stable operation on 8–9 V supply rails. |
| Breakdown Voltage (VBR) | 9.44–10.40 V at 1 mA - precise avalanche onset guarantees predictable clamping initiation across temperature. |
| Clamping Voltage (VCL) | 14.4 V at IPPM = 41.7 A - limits downstream IC voltage stress during worst-case surge, protecting 12 V system components. |
| Reverse Leakage (IRM) | ≤ 0.01 µA at VRWM - negligible standby current preserves battery life in always-on automotive modules. |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2) - withstands human-body model events without parametric shift or failure. |
| Thermal Resistance (Rth(j-sp)) | 12 K/W - enables efficient heat transfer from junction to PCB solder point, supporting sustained surge duty cycles. |
Pinout & Package
SOD128 (CFP5) plastic surface-mounted package: 2-terminal, 4 mm pitch, 3.8 mm × 2.6 mm × 1 mm body; marking bar denotes cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., 12 V rail); carries surge current to ground during clamping event. |
| 2 | Anode (A) | Connected to circuit ground; completes low-impedance path for transient energy dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications per revision history v.3 (2025), including temperature cycling and HBM testing. |
| Low-profile SOD128 package | 1 mm height enables placement under connectors or near ECU housings without mechanical interference. |
| High surge current capability | IPPM = 41.7 A (10/1000 µs) provides margin against ISO 7637-2 Pulse 1/2/5a transients in 12 V systems. |
| Ultra-low leakage | IRM ≤ 0.01 µA minimizes quiescent power loss in battery-backed modules like door controllers and sensors. |
| Controlled clamping ratio | VCL/VBR ≈ 1.53 ensures tight voltage limiting without excessive overshoot during fast-rising transients. |
Applications
| Automotive Body Control Module | Industrial PLC Power Input |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.5A | Same VRWM (8.5 V) but lower PPPM (400 W); VCL = 14.4 V at 27.8 A; SMA package (2.5 mm height). | Lacks AEC-Q101 qualification; higher Rth(j-a) = 50 K/W limits thermal performance in dense layouts. | Select when cost sensitivity outweighs automotive compliance and thermal margin requirements. |
| TPSMD8.5A | Higher VRWM tolerance (±5% vs ±3.5%); VCL = 15.0 V at 40 A; same SOD128 footprint but non-AEC-Q101. | Not validated for automotive temperature cycling; IRM = 1 µA - 100× higher leakage than PTVS8V5P1UP,115. | Prefer only for non-automotive industrial use where leakage current is not critical. |
Compared with SMAJ8.5A and TPSMD8.5A, PTVS8V5P1UP,115 delivers superior thermal management (Rth(j-sp) = 12 K/W), certified automotive reliability, and ultra-low leakage - making it the optimal choice for safety-critical 12 V rail protection where long-term stability and ESD robustness are mandatory.

FAQ
Is PTVS8V5P1UP,115 qualified for automotive applications?
Yes - per revision history v.3 (December 2025), PTVS8V5P1UP,115 is explicitly listed among the 25 products upgraded to standard AEC-Q101 qualification, covering temperature cycling, HBM ESD, and mechanical shock testing required for automotive ECUs and body control modules.
What is the maximum clamping voltage under full-rated surge current?
At IPPM = 41.7 A (10/1000 µs waveform), the clamping voltage VCL is guaranteed ≤ 14.4 V - measured per IEC 61643-321 test conditions and confirmed in Table 8 of the datasheet for PTVS8V5P1UP.
Can PTVS8V5P1UP,115 be used in bidirectional configurations?
No - it is a unidirectional TVS diode with anode and cathode terminals; bidirectional protection requires two devices in series opposition or a dedicated bidirectional part such as PTVS8V5S1UP,115.
How does its thermal resistance compare to standard SMA packages?
With Rth(j-sp) = 12 K/W, PTVS8V5P1UP,115 dissipates heat 4× more effectively than typical SMA-packaged TVS diodes (Rth(j-sp) ≈ 45–50 K/W), enabling higher surge repetition rates in thermally constrained automotive PCBs.
