Product details
Overview
PTVS8V5P1UTP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature overvoltage protection in automotive 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 junction temperature rating up to 185 °C - enabling robust ESD and surge protection in engine control units and battery management systems.
For engineers reviewing the PTVS8V5P1UTP-QX datasheet, PTVS8V5P1UTP-QX pinout, PTVS8V5P1UTP-QX application, or PTVS8V5P1UTP-QX equivalent, key selection criteria include its AEC-Q101 qualification, low IRM = 0.01 µA at VRWM, 1 mm profile for space-constrained PCB layouts, and thermal resistance Rth(j-sp) = 12 K/W for effective transient energy dissipation in under-hood environments.
Technical Context
This unidirectional TVS diode operates as a clamping device: it remains high-impedance below VRWM = 8.5 V, then avalanches sharply at VBR = 9.44–10.40 V (min–max) to limit transients. Its IEC 61643-321-compliant 10/1000 µs waveform response ensures predictable clamping during automotive load-dump and ISO 7637-2 pulses.
Thermal design is enabled by dual-path heat transfer: low Rth(j-sp) = 12 K/W to solder point supports localized thermal relief, while Rth(j-a) = 60 K/W on ceramic PCB allows stable operation at Tamb = 185 °C. The cathode-marked SOD128 package integrates seamlessly into automated SMT lines with standard reflow footprints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W - sustains 10/1000 µs surges without degradation in automotive-grade thermal cycling |
| Reverse Standoff Voltage (VRWM) | 8.5 V - blocks normal 8–9 V supply rail noise while triggering only on overvoltage events |
| Clamping Voltage (VCL) | 14.4 V at IPPM = 41.7 A - limits downstream IC voltage stress to safe levels during 100 A-equivalent transients |
| Reverse Leakage (IRM) | 0.01 µA at VRWM - negligible standby current draw in always-on vehicle modules |
| Junction Temperature (Tj) | 185 °C max - enables placement near hot components like DC-DC converters or motor drivers |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2) - exceeds automotive ESD immunity requirements |
| Package | SOD128 (CFP5) - 3.8 × 2.6 × 1.0 mm surface-mount footprint with cathode bar marking |
Pinout & Package
SOD128 (CFP5) plastic surface-mounted package: 2-terminal, flat lead, 4 mm pitch, 1 mm height, tin-plated terminations. Cathode identified by molded bar marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected circuit's positive rail; avalanche conduction path during overvoltage |
| 2 (A) | Anode | Connected to ground reference; completes clamping loop and defines unidirectional polarity |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test standard - eliminates need for additional qualification testing |
| High-temperature stability | Tj ≤ 185 °C and Tamb ≤ 185 °C - enables direct mounting on high-power boards without derating |
| Low-profile SMD package | 1 mm height - fits beneath connectors or shields in compact ECUs and ADAS modules |
| Low clamping ratio | VCL / VRWM = 1.69 - tight voltage margin preserves headroom for 12 V system ICs with 16 V absolute max ratings |
| Controlled thermal resistance | Rth(j-sp) = 12 K/W - enables rapid heat extraction via cathode pad, critical for repetitive surge handling |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: Protects 12 V supply input against load dump (ISO 7637-2 Pulse 5a) and alternator ripple in gasoline/diesel ECUs. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed upstream of DC-DC converter input filter. Use Value: Limits transient voltage to ≤14.4 V, preventing latch-up or damage to 16 V-rated buck controllers and microcontrollers. |

Use Scenario: Protects 5 V/3.3 V camera module power pins from cable-induced surges in rear-view or surround-view systems. IC Role / Device Role / Timing Role: Low-capacitance TVS (Cd < 100 pF at 1 V) placed adjacent to image sensor power pins. Use Value: 1 mm height allows placement under FPC connector; 185 °C Tj rating supports operation behind heated rear windows. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.5A-Q | Lower PPPM = 400 W; VRWM = 8.5 V; VCL = 14.4 V; SMC package (2.5 mm height) | Not AEC-Q101 qualified; higher Rth(j-a) = 100 K/W limits high-temp deployment | Select when cost sensitivity outweighs automotive qualification and thermal performance needs |
| TPSMA6L8.5A-Q | Same VRWM/VCL; PPPM = 600 W; AEC-Q101 qualified; SOD123FL package (1.1 mm height) | Higher IRM = 1 µA - increases standby current in always-on modules | Prefer where tighter board-level ESD compliance (IEC 61000-4-2) is prioritized over ultra-low leakage |
Compared with SMAJ8.5A-Q, PTVS8V5P1UTP-QX delivers superior thermal resilience and automotive qualification; versus TPSMA6L8.5A-Q, it offers 100× lower leakage for extended battery life - making it optimal for safety-critical, high-temperature, low-power automotive nodes.

FAQ
What is the maximum operating temperature for PTVS8V5P1UTP-QX?
The device supports continuous operation up to ambient temperature Tamb = 185 °C and junction temperature Tj = 185 °C, validated per AEC-Q101 high-temperature operating life (HTOL) testing. This enables direct placement on power stages in engine compartments without thermal derating.
How does PTVS8V5P1UTP-QX differ from standard SOD123 TVS diodes?
It uses the SOD128 (CFP5) package with 1 mm height and optimized thermal pad layout, achieving Rth(j-sp) = 12 K/W - 50% lower than typical SOD123 - and is fully AEC-Q101 qualified with extended 185 °C rating, unlike most SOD123 variants rated only to 150 °C.
Is PTVS8V5P1UTP-QX suitable for bidirectional transient protection?
No - it is strictly unidirectional. Its anode-to-cathode configuration conducts only during positive transients on the cathode side. For bidirectional protection (e.g., data lines), a symmetric pair or dedicated bidirectional TVS like PTVS8V5S1UTP-QX would be required.
What is the clamping behavior at elevated temperatures?
VCL increases by approximately +0.5 V from 25 °C to 150 °C due to positive temperature coefficient of the avalanche breakdown; full derating curves are provided in Figure 2 of the datasheet, confirming 14.4 V clamping remains within spec up to Tj = 185 °C.
