Product details
Overview
PTVS8V0P1UTP-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. Confirmed parameters: VRWM = 8.0 V, VBR(min) = 8.89 V at 1 mA, VCL = 13.6 V at IPPM = 44.1 A (10/1000 µs), Tj(max) = 185 °C, and IRM = 0.03 µA at VRWM.
For engineers reviewing the PTVS8V0P1UTP-QX datasheet, PTVS8V0P1UTP-QX pinout, PTVS8V0P1UTP-QX application, or PTVS8V0P1UTP-QX equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance values (Rth(j-sp) = 12 K/W), clamping behavior under IEC 61643-321 surge, and direct replacement guidance for automotive-grade TVS selection.
Technical Context
This unidirectional TVS operates as a voltage-clamping device in series with power supply inputs, triggering conduction when reverse voltage exceeds 8.0 V standoff level. Its silicon junction exhibits low leakage (0.03 µA), tight breakdown tolerance (8.89–9.83 V), and stable clamping (13.6 V) under 44.1 A peak pulse current per IEC 61643-321.
Thermal design is enabled by low Rth(j-sp) = 12 K/W to solder point and rated junction temperature up to 185 °C - validated per AEC-Q101 stress testing. The SOD128 package supports surface-mount reflow with 1 mm profile, optimized for space-constrained engine control units and battery management systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 8.0 V - Maximum continuous reverse operating voltage before clamping initiates; defines minimum system rail margin. |
| VBR (min) | 8.89 V at 1 mA - Guaranteed breakdown onset; ensures reliable turn-on above nominal rail voltage. |
| VCL | 13.6 V at IPPM = 44.1 A - Clamped voltage during 10/1000 µs surge; determines protected IC's maximum transient exposure. |
| PPPM | 600 W - Peak pulse power handling per IEC 61643-321; enables robust protection against ISO 7637-2 Pulse 1/2a/5a transients. |
| IRM | 0.03 µA at VRWM - Ultra-low leakage preserves battery life in always-on automotive modules. |
| Tj(max) | 185 °C - Junction temperature rating validated per AEC-Q101; supports under-hood placement near engines or inverters. |
| Rth(j-sp) | 12 K/W - Thermal resistance to solder point; enables effective heat dissipation on standard PCB copper pads. |
Pinout & Package
The PTVS8V0P1UTP-QX uses a 2-terminal SOD128 (CFP5) plastic surface-mount package measuring 3.8 mm × 2.6 mm × 1.0 mm, with cathode marked by a bar on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected circuit's positive rail; conducts surge current to ground when reverse-biased beyond VRWM. |
| 2 (A) | Anode | Connected to system ground; completes clamping path during transient events. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, HTRB, and ESD (±30 kV contact); eliminates qualification overhead for Tier 1 suppliers. |
| 185 °C junction rating | Enables direct mounting on high-temperature PCB zones (e.g., near DC-DC converters or motor drivers) without derating. |
| 1 mm package height | Reduces mechanical interference in stacked modules and allows conformal coating over top surface without bridging. |
| Low Rth(j-sp) = 12 K/W | Permits sustained surge handling without external heatsinking when mounted on ≥1 cm² cathode pad per JEDEC standards. |
| 0.03 µA IRM at VRWM | Minimizes standby power loss in 12 V/24 V always-on domains such as CAN gateway ECUs and telematics units. |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Infotainment Power Rail |
|---|---|
Use Scenario: Protects 12 V input of gasoline/diesel ECU against load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between battery feed and primary DC-DC converter input. Use Value: Limits transient voltage to ≤13.6 V, preventing damage to 16 V-rated input capacitors and enabling single-stage input filtering. |
Use Scenario: Shields USB-C PD and display power supplies in head units from jump-start surges and hot-swap transients. IC Role / Device Role / Timing Role: Front-end TVS on 5 V/12 V auxiliary rails upstream of LDOs and PMICs. Use Value: Withstands 44.1 A peak current while maintaining <14 V clamping, preserving downstream USB PHY and MIPI DSI timing integrity. |
| Electric Power Steering (EPS) Module | On-Board Charger (OBC) Auxiliary Supply |
Use Scenario: Guards 24 V auxiliary supply in EPS against inductive kickback from motor driver FETs and CAN bus coupling. IC Role / Device Role / Timing Role: Bidirectional protection not required; unidirectional TVS selected for lower capacitance and tighter VBR tolerance. Use Value: 0.03 µA leakage avoids drain on 24 V backup battery during key-off; 185 °C rating survives proximity to motor driver ICs. |
Use Scenario: Safeguards 12 V control logic supply in OBC against grid-side transients coupled via shared grounding or transformer parasitics. IC Role / Device Role / Timing Role: Secondary-side TVS on isolated auxiliary supply output, after flyback transformer and post-regulator. Use Value: 12 K/W Rth(j-sp) allows direct thermal coupling to metal-core PCB, eliminating need for thermal vias in high-density OBC layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ8.0A | Same VRWM (8.0 V), but VCL = 13.6 V at 45.5 A; Rth(j-a) = 60 K/W vs. 12 K/W to solder point; no AEC-Q101 certification. | Rated for industrial/commercial use only; unsuitable for production automotive programs requiring PPAP documentation. | Select only for non-automotive prototypes or cost-sensitive consumer power adapters where thermal performance is secondary. |
| Vishay SMA6J8.0A | Identical VRWM and VCL, but Tj(max) = 150 °C and IRM = 1 µA - 33× higher leakage than PTVS8V0P1UTP-QX. | Limited to ambient-temperature cabin modules; cannot support under-hood deployment or long-term battery drain constraints. | Acceptable for infotainment head units with active cooling, but avoid in always-on telematics or ADAS sensor hubs. |
Compared with SMAJ8.0A and SMA6J8.0A, the PTVS8V0P1UTP-QX uniquely combines AEC-Q101 compliance, 185 °C operation, ultra-low leakage, and superior thermal coupling - making it the sole choice for production automotive power protection where reliability, temperature resilience, and standby current are jointly constrained.
