Product details
Overview
PTVS11VP1UTP-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 = 11 V, VBR(min) = 12.2 V at 1 mA, VCL = 18.2 V at IPPM = 33.0 A (10/1000 μs), and operates up to Tj = 185 °C. It is AEC-Q101 qualified and used in 12 V battery line protection.
For engineers reviewing the PTVS11VP1UTP-QX datasheet, PTVS11VP1UTP-QX pinout, PTVS11VP1UTP-QX application, or PTVS11VP1UTP-QX equivalent, key selection criteria include clamping voltage under 18.2 V at 33 A, reverse leakage ≤0.005 μA at VRWM, thermal resistance to solder point of 12 K/W, and compatibility with reflow/wave soldering footprints per SOD128 outline.
Technical Context
This unidirectional TVS diode operates in avalanche breakdown mode to clamp transient surges on DC power lines. Its junction temperature rating of 185 °C enables use in engine bay and powertrain modules where ambient temperatures exceed 150 °C.
The device uses a planar silicon junction structure optimized for low dynamic impedance and stable clamping across temperature. Its 1 mm profile and 3.8 mm × 2.6 mm footprint support compact placement near connectors or ECUs without compromising thermal dissipation via cathode tab solder point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W (IEC 61643-321, 10/1000 μs); sustains single high-energy transients like ISO 7637-2 pulse 5a. |
| Reverse Standoff Voltage | VRWM = 11 V; maximum continuous DC voltage before significant leakage; matches nominal 12 V automotive systems. |
| Breakdown Voltage | VBR = 12.2–13.5 V at 1 mA; ensures reliable triggering above normal operating voltage with margin. |
| Clamping Voltage | VCL = 18.2 V at IPPM = 33.0 A; limits downstream IC voltage stress during surge events. |
| Reverse Leakage | IRM ≤ 0.005 μA at VRWM and Tj = 25 °C; negligible standby current impact on low-power circuits. |
| Junction Temperature | Tj(max) = 185 °C; supports operation in under-hood environments without derating up to rated power. |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2); protects against human-body and system-level ESD events. |
Pinout & Package
Package: SOD128 (CFP5) - surface-mounted plastic package, 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm pitch, two-terminal configuration with cathode bar marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., battery rail); marking bar identifies this terminal; primary heat path to PCB via cathode tab. |
| 2 (A) | Anode | Connected to ground reference; completes clamping path during transient; low-inductance layout critical for fast response. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTGB, HTRB, and temperature cycling per discrete semiconductor standard. |
| High-temperature stability | Rated peak pulse power remains ≥80% of 600 W up to Tj = 150 °C (Fig. 2), enabling full surge capability in hot environments. |
| Low-profile SMD package | 1.0 mm max height allows integration into space-constrained modules such as junction boxes and ADAS sensor housings. |
| Thermal resistance to solder point | Rth(j-sp) = 12 K/W; enables efficient heat transfer from junction to PCB copper through cathode tab, reducing thermal runaway risk. |
| Low capacitance | Typical Cd = ~100 pF at VR = 0 V (per Fig. 4 curve #2); minimizes signal distortion on DC power lines with fast edges. |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) Battery Rail |
|---|---|
Use Scenario: Protects microcontroller and CAN transceiver power inputs from load dump and jump-start transients in gasoline/diesel engine compartments. IC Role / Device Role: Unidirectional clamping TVS placed between battery feed and local LDO/regulator input. Use Value: Limits voltage to ≤18.2 V during 33 A surge, preventing latch-up or permanent damage to 5 V/3.3 V logic supplies. |
Use Scenario: Shields BCM power domain from ISO 7637-2 pulses during door actuation, lighting loads, and alternator regulation faults. IC Role / Device Role: Primary overvoltage clamp on 12 V main rail upstream of DC-DC converters and power switches. Use Value: Withstands repeated 600 W pulses while maintaining IRM ≤0.005 μA, ensuring no leakage-induced battery drain over 15-year vehicle life. |
| ADAS Camera Power Supply | Electric Power Steering (EPS) Motor Driver |
Use Scenario: Guards image sensor and serializer ICs in front-facing cameras exposed to under-hood thermal cycling and ESD. IC Role / Device Role: Secondary protection stage after fuse and common-mode choke, located adjacent to camera module connector. Use Value: 185 °C junction rating allows operation at PCB temperatures >125 °C without derating; ±30 kV ESD rating prevents pixel corruption from handling discharge. |
Use Scenario: Safeguards gate drivers and current sense amplifiers in EPS motor control units subjected to battery reversal and inductive kickback. IC Role / Device Role: Bidirectional protection not required; unidirectional TVS placed on low-side switch return path to suppress negative transients. Use Value: Clamps negative spikes to <−0.7 V (forward conduction) and positive surges to ≤18.2 V, preserving MOSFET gate oxide integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A-Q | Lower PPPM = 400 W; VRWM = 11 V; VCL = 18.2 V at IPPM = 22 A; Tj(max) = 150 °C; not AEC-Q101 qualified. | Limited to cabin or non-critical modules; unsuitable for under-hood use above 125 °C ambient. | Select only if cost sensitivity outweighs thermal and qualification requirements. |
| TPSMA6L11-Q | PPPM = 600 W; VRWM = 11 V; VCL = 19.5 V at IPPM = 30.8 A; Tj(max) = 175 °C; AEC-Q101 qualified; SOD123 package (higher Rth(j-a)). | Higher clamping voltage increases stress on downstream regulators; larger thermal resistance reduces sustained surge margin. | Prefer when existing SOD123 footprint must be retained; verify VCL margin with regulator absolute max ratings. |
Compared with SMAJ11A-Q and TPSMA6L11-Q, PTVS11VP1UTP-QX delivers superior thermal robustness (185 °C vs. 150/175 °C), lower clamping at rated current (18.2 V vs. 18.2/19.5 V), and lowest Rth(j-sp) (12 K/W), making it optimal for high-reliability automotive power rail protection where thermal and surge margins are constrained.

FAQ
What is the maximum clamping voltage of PTVS11VP1UTP-QX at its rated peak pulse current?
The clamping voltage VCL is 18.2 V measured at IPPM = 33.0 A using the IEC 61643-321 10/1000 μs waveform. This value is guaranteed across temperature and represents the maximum voltage seen by downstream circuitry during a full-rated surge event.
How does the thermal resistance to solder point (Rth(j-sp)) impact PCB layout design?
Rth(j-sp) = 12 K/W indicates highly efficient heat transfer from junction to cathode solder joint. To realize this, the cathode pad must be connected to ≥1 cm² of 1 oz copper with multiple thermal vias to inner/ground planes-per Nexperia's recommended footprint in Figure 7.
Is PTVS11VP1UTP-QX suitable for bidirectional transient protection?
No-it is a unidirectional TVS diode intended for DC power line protection with defined polarity. For AC or bipolar signal lines, a bidirectional variant (e.g., PTVS11VU1UTP-QX) or back-to-back configuration would be required.
What AEC-Q101 stress tests has PTVS11VP1UTP-QX passed?
It has completed the full AEC-Q101-001 qualification suite including High-Temperature Reverse Bias (HTRB), High-Temperature Gate Bias (HTGB), Temperature Cycling (TC), and Unbiased Highly Accelerated Stress Test (UHAST), confirming reliability for automotive under-hood deployment.
