Product details
Overview
PTVS36VP1UTP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature transient overvoltage protection in automotive power rails. It features VRWM = 36 V, VBR(min) = 40.0 V at 1 mA, VCL = 58.1 V at IPPM = 10.3 A (10/1000 µs), and operates up to Tj = 185 °C.
For engineers reviewing the PTVS36VP1UTP-QX datasheet, PTVS36VP1UTP-QX pinout, PTVS36VP1UTP-QX application, or PTVS36VP1UTP-QX equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance values, clamping behavior under surge, and real-world use context in automotive and industrial power systems.
Technical Context
This TVS diode uses a planar silicon junction optimized for fast response (<1 ns) to ESD and lightning-induced transients per IEC 61643-321 (10/1000 µs). Its unidirectional configuration protects against positive-going surges on DC lines with cathode-anode polarity alignment.
Thermal design is enabled by low Rth(j-sp) = 12 K/W to solder point and stable PPPM derating-maintaining 80% of 600 W rating at Tj = 150 °C per Fig. 2. ESD robustness includes ±30 kV contact discharge (IEC 61000-4-2) and 8 kV HBM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W - Sustains 10/1000 µs surge without failure; enables protection of 12 V/24 V/48 V automotive buses against ISO 7637-2 pulses. |
| Reverse Standoff Voltage (VRWM) | 36 V - Maximum continuous DC operating voltage before leakage exceeds 0.001 µA; matches nominal 36 V battery or auxiliary rail systems. |
| Breakdown Voltage (VBR) | 40.0–44.2 V at 1 mA - Tight 10.5% tolerance ensures predictable turn-on during overvoltage events without premature conduction. |
| Clamping Voltage (VCL) | 58.1 V at IPPM = 10.3 A - Limits downstream voltage to safe levels during full-rated surge; <22 V overshoot above VRWM. |
| Junction Temperature (Tj) | 185 °C - Enables placement near hot components (e.g., power converters, engine control units) without derating penalties. |
| ESD Rating | ±30 kV contact discharge - Meets stringent automotive ESD immunity requirements per ISO 10605 without external shielding. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and UHAST; suitable for safety-critical ECUs. |
Pinout & Package
SOD128 (CFP5) surface-mount plastic package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat lead profile optimized for automated reflow and space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line's higher-potential side (e.g., +36 V rail); marking bar identifies this terminal. |
| 2 | Anode (A) | Connected to ground or lower-potential reference; completes current path during transient clamp event. |
Key Features
| Feature | Design Value |
|---|---|
| High-Temperature Stability | Tj ≤ 185 °C operation with no parameter drift-eliminates need for thermal derating in under-hood modules. |
| Low Profile Height | 1.0 mm max - Enables placement beneath shields or in stacked board assemblies without mechanical interference. |
| AEC-Q101 Qualification | Qualified per stress test standard for discrete semiconductors-reduces validation effort for Tier 1 automotive designs. |
| Low Leakage Current | IRM ≤ 0.001 µA at VRWM - Prevents parasitic drain in always-on battery circuits (e.g., CAN wake-up lines). |
| Robust ESD Immunity | ±30 kV contact / ±30 kV air discharge - Survives assembly handling and field-level ESD without degradation. |
Applications
| Automotive Power Rail Protection | Industrial DC 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 |
|---|---|---|---|
| Littelfuse SMAJ36A | Same VRWM (36 V), but lower PPPM = 400 W; VCL = 58.1 V at IPPM = 6.9 A; Rth(j-a) = 60 K/W vs. 120 K/W for Nexperia part. | Less suited for sustained high-temp environments due to lower Tj max (150 °C vs. 185 °C) and no AEC-Q101 listing. | Select when cost sensitivity outweighs automotive qualification or thermal margin needs. |
| Vishay SMF36A | Identical VRWM and VCL (58.1 V), but rated PPPM = 200 W; Tj max = 150 °C; ESD rating only 30 kV air (not contact). | Not qualified to AEC-Q101; limited to non-safety-critical industrial use where surge energy is lower. | Choose only for legacy designs with proven margin or non-automotive applications with infrequent transients. |
Compared with Littelfuse SMAJ36A and Vishay SMF36A, PTVS36VP1UTP-QX delivers 50% higher surge power handling, 35 °C higher junction temperature capability, and full AEC-Q101 compliance-making it the only option qualified for next-generation automotive 36 V systems requiring zero derating at extreme temperatures.

FAQ
What is the maximum clamping voltage of PTVS36VP1UTP-QX at its rated peak pulse current?
The clamping voltage (VCL) is 58.1 V at IPPM = 10.3 A under the standardized 10/1000 µs waveform per IEC 61643-321. This value is measured at Tj = 25 °C and represents the maximum voltage seen by downstream circuitry during a full-rated surge event.
Is PTVS36VP1UTP-QX suitable for bidirectional transient protection?
No-it is a unidirectional TVS diode, configured to clamp only positive transients relative to ground. For bidirectional protection, two PTVS36VP1UTP-QX devices must be connected anode-to-anode or used in conjunction with a complementary device such as a bidirectional TVS with matching VRWM.
How does the thermal resistance of PTVS36VP1UTP-QX impact PCB layout?
With Rth(j-sp) = 12 K/W to the cathode solder point, optimal thermal performance requires a minimum 1 cm² copper pour connected to Pin 1 (cathode) on FR4 PCBs. Smaller pads increase junction temperature rise and reduce surge endurance-layout guidance is provided in Figure 7 of the datasheet.
Does PTVS36VP1UTP-QX require derating at elevated ambient temperatures?
Yes-while the device supports Tj up to 185 °C, its PPPM must be derated above Tamb = 25 °C per Fig. 2. At Tamb = 125 °C, PPPM drops to ~480 W (80% of rating); full 600 W is only guaranteed at 25 °C ambient with proper heatsinking and airflow.
