Product details
Overview
PTVS20VP1UTP-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 = 20 V, VBR(min) = 22.2 V, VCL = 32.4 V at IPPM = 18.5 A (10/1000 µs), and operates up to Tj = 185 °C. Used in 12 V/24 V vehicle battery line protection against ISO 7637-2 pulses.
For engineers reviewing the PTVS20VP1UTP-QX datasheet, PTVS20VP1UTP-QX pinout, PTVS20VP1UTP-QX application, or PTVS20VP1UTP-QX equivalent, this page delivers verified electrical specs, thermal derating behavior, AEC-Q101 qualification status, cathode/anode terminal mapping, and automotive-grade clamping performance under IEC 61643-321 waveform conditions.
Technical Context
This TVS diode uses a planar silicon junction optimized for stable breakdown voltage (VBR = 22.2–24.5 V) and low clamping ratio (VCL/VBR ≈ 1.45) across temperature. Its unidirectional architecture provides reverse-biased surge suppression only, requiring correct polarity placement on DC supply lines.
Thermal design relies on low Rth(j-sp) = 12 K/W to solder point and supports continuous operation at Tamb = 185 °C when mounted per FR4 footprint guidelines. ESD robustness includes ±30 kV contact discharge (IEC 61000-4-2) and 8 kV HBM rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W (IEC 61643-321, 10/1000 µs); sustains transient surges without thermal runaway |
| Reverse Standoff Voltage | VRWM = 20 V; maximum continuous DC voltage before leakage exceeds 0.001 µA |
| Breakdown Voltage | VBR = 22.2–24.5 V at IR = 1 mA; defines onset of avalanche conduction during transients |
| Clamping Voltage | VCL = 32.4 V at IPPM = 18.5 A; limits downstream IC voltage during worst-case surge |
| Junction Temperature | Tj(max) = 185 °C; enables placement near hot engine control units without derating |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2); protects against human-handling events pre-assembly |
| AEC-Q101 Qualified | Qualified per Automotive Electronics Council stress test standard; validated for under-hood use |
Pinout & Package
Package: CFP5 (SOD128), surface-mount plastic package with 2 terminals, 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm pitch, and cathode-marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., +12 V rail); marking bar identifies this terminal |
| 2 | Anode (A) | Connected to ground reference; completes current path during reverse-biased surge event |
Key Features
| Feature | Design Value |
|---|---|
| High-Temperature Operation | Rated for continuous use at Tj ≤ 185 °C - eliminates need for thermal margining in engine bay designs |
| Low Profile Height | 1.0 mm max package height - fits under low-clearance shields and compact automotive modules |
| Automotive Qualification | AEC-Q101 qualified - meets stress-test requirements for vibration, temperature cycling, and humidity resistance |
| Stable Clamping Performance | VCL variation < ±5 % over −55 °C to +150 °C - ensures consistent protection across ambient extremes |
| Low Leakage Current | IRM ≤ 0.001 µA at VRWM - prevents battery drain in always-on vehicle subsystems |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) CAN Bus Line |
|---|---|
Use Scenario: Protects 12 V supply input of engine ECU against load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and input filter capacitor to clamp surges before LDO regulators. Use Value: Limits peak voltage to ≤32.4 V, preventing damage to 36 V-rated input stages and enabling smaller input capacitors. |
Use Scenario: Shields CAN transceiver VCC and signal lines from coupled transients induced by nearby solenoid switching. IC Role / Device Role / Timing Role: Mounted on 5 V power rail feeding CAN PHY; suppresses fast-rising spikes (<100 ns) before they couple into differential bus. Use Value: Low capacitance (<50 pF at 0 V) avoids CAN signal edge distortion while providing 600 W surge headroom. |
| ADAS Camera Power Supply | Electric Power Steering (EPS) Motor Driver |
Use Scenario: Secures 5 V/3.3 V imaging sensor supply in front-facing ADAS camera exposed to ignition noise and EMI. IC Role / Device Role / Timing Role: Placed immediately after DC-DC converter output to absorb sub-microsecond transients from nearby radar modules. Use Value: 185 °C junction rating allows mounting directly on same PCB layer as image sensor without thermal isolation. |
Use Scenario: Guards gate driver IC supply against inductive kickback from 3-phase motor phase switching. IC Role / Device Role / Timing Role: Connected across HV-side bootstrap capacitor to clamp overshoot during high-side FET turn-off. Use Value: 600 W pulse rating handles repetitive 10/1000 µs spikes from PWM commutation without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ20A-Q | Lower PPPM = 400 W; VRWM = 20 V; VCL = 32.4 V; same SOD-123 package | Limited to lower-energy transients; not rated for Tj > 175 °C | Select when cost sensitivity outweighs need for full 600 W headroom or extended temperature range |
| TPSMD20H | Higher VRWM = 22 V; VCL = 34.4 V; PPPM = 600 W; AEC-Q101 qualified; DO-214AB package | Larger footprint (7.1 mm × 6.2 mm); higher thermal mass but less suitable for ultra-thin modules | Choose when board space permits larger package and higher standoff margin is required for 24 V systems |
Compared with SMAJ20A-Q and TPSMD20H, PTVS20VP1UTP-QX uniquely combines 600 W surge capacity, 1 mm profile, and 185 °C operation in SOD128 - making it optimal for space-constrained, high-temperature automotive modules where thermal and mechanical envelope are critical.

FAQ
What is the maximum clamping voltage of PTVS20VP1UTP-QX at its rated peak pulse current?
The clamping voltage VCL is 32.4 V at IPPM = 18.5 A under IEC 61643-321 10/1000 µs waveform conditions. This value is measured at Tj = 25 °C and remains within ±5 % across −55 °C to +150 °C operating range, ensuring predictable protection behavior in automotive thermal environments.
Does PTVS20VP1UTP-QX support bidirectional transient suppression?
No, PTVS20VP1UTP-QX is a unidirectional TVS diode. It conducts only during reverse-biased overvoltage events - i.e., when cathode voltage exceeds anode voltage by ≥VBR. For AC or bipolar surge protection, a separate bidirectional device such as PTVS20VB1UTP-QX must be used.
How does the 185 °C junction temperature rating impact PCB layout?
The 185 °C rating allows placement near heat sources like power MOSFETs or DC-DC converters without thermal derating, provided the solder-point thermal resistance (Rth(j-sp) = 12 K/W) is achieved using the recommended 1 cm² cathode pad on FR4. No additional heatsinking or spacing is required beyond the CFP5 footprint shown in Figure 7.
Is PTVS20VP1UTP-QX compatible with lead-free reflow processes?
Yes, PTVS20VP1UTP-QX is qualified for standard lead-free reflow per JEDEC J-STD-020. Its CFP5 package withstands peak temperatures up to 260 °C for 30 seconds. The recommended reflow profile uses a maximum ramp rate of 3 °C/s and maintains time above liquidus (TAL) between 60–150 s, matching IPC-7095 guidelines for SOD128 devices.
