Product details
Overview
PTVS17VP1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at 17 V reverse standoff voltage (VRWM), with 27.6 V clamping voltage (VCL) at 21.7 A peak pulse current (IPPM), and qualified to AEC-Q101 for under-hood power rail and ECU interface protection.
For engineers reviewing the PTVS17VP1UP-QX datasheet, PTVS17VP1UP-QX pinout, PTVS17VP1UP-QX application, or PTVS17VP1UP-QX equivalent, this device serves as a surface-mount, low-profile (1 mm height) transient suppressor for 12 V/24 V automotive systems requiring high ESD immunity (±30 kV contact), low leakage (≤0.1 µA), and stable clamping performance across temperature.
Technical Context
This unidirectional TVS diode operates in avalanche breakdown mode during transients, clamping voltage spikes above VRWM = 17 V while maintaining <0.1 µA reverse leakage at rated standoff. Its junction-to-solder-point thermal resistance is 12 K/W, enabling effective heat dissipation in compact automotive PCB layouts.
The device conforms to IEC 61643-321 (10/1000 µs waveform) and supports peak pulse power of 600 W at Tj = 25 °C, derating to ~400 W at 125 °C per Fig. 2 - critical for sustained load-dump immunity in engine control modules and body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 17 V - maximum continuous reverse operating voltage before clamping begins; matches nominal 12 V automotive systems with margin for ripple and load dump overshoot. |
| VCL @ IPPM | 27.6 V - clamped voltage at 21.7 A peak pulse current; ensures downstream 3.3 V/5 V logic and MCU I/O remain within safe absolute maximum ratings. |
| PPPM | 600 W - peak pulse power handling per IEC 61643-321 (10/1000 µs); sufficient for ISO 7637-2 Pulse 5a (load dump) suppression without derating. |
| IRM | ≤0.1 µA - reverse leakage at VRWM; minimizes quiescent current drain in always-on vehicle networks (e.g., CAN standby). |
| Rth(j-sp) | 12 K/W - thermal resistance from junction to solder point; enables reliable operation up to 150 °C junction temperature with standard FR4 PCB layout. |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact discharge); protects against human-body and cable-discharge events in infotainment and sensor interfaces. |
Pinout & Package
SOD128 (CFP5) plastic surface-mounted package: 2-terminal, 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, marking bar denotes cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., CAN_H, LIN, 12 V rail); polarity-sensitive - reverse connection disables clamping function. |
| 2 (A) | Anode | Connected to ground reference plane; low-inductance grounding path required to achieve specified VCL and IPPM performance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, humidity bias, and mechanical shock - eliminates need for additional qualification testing in Tier-1 designs. |
| 1 mm profile | Enables placement beneath connectors and in tight engine-control module cavities where Z-height is constrained by housing or shielding. |
| Low IRM ≤ 0.1 µA | Reduces standby current in always-on domains (e.g., alarm systems, telematics), extending battery life in key-off scenarios. |
| 600 W PPPM at 25 °C | Supports single-event suppression of ISO 7637-2 Pulse 5a (load dump) up to 120 V/500 ms without degradation or thermal runaway. |
Applications
| Automotive Power Rail Protection | CAN Bus Interface Protection |
|---|---|
|
Use Scenario: 12 V battery feed line in engine control unit (ECU) exposed to load dump transients up to 120 V. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and bulk capacitor to clamp overvoltage before it reaches DC-DC converters and microcontrollers. Use Value: Limits peak voltage to 27.6 V at 21.7 A, preventing damage to 36 V-rated input stages and ensuring system reset-free operation after transient events. |
Use Scenario: High-speed CAN FD transceiver (e.g., TJA1044) on vehicle chassis network subjected to ESD and coupled noise. IC Role / Device Role / Timing Role: Bidirectional protection not required; unidirectional TVS on CAN_H line referenced to ground provides lower capacitance (<50 pF) and tighter clamping than bidirectional alternatives. Use Value: Clamps fast ESD pulses (IEC 61000-4-2) to <30 V while adding <15 pF parasitic capacitance - preserving signal integrity up to 5 Mbps. |
| Body Control Module I/O Protection | Infotainment Power Supply Input |
|
Use Scenario: LIN bus or sensor supply line (5 V or 12 V) in door module or seat controller exposed to wiring harness coupling. IC Role / Device Role / Timing Role: Point-of-load TVS on each protected output, placed immediately before connector to minimize loop inductance and improve clamping response. Use Value: Achieves sub-100 ns response time and holds clamped voltage below 30 V, protecting automotive-grade op-amps and ASICs with 36 V absolute max ratings. |
Use Scenario: 5 V/3.3 V power input to head unit mainboard, fed from central domain controller via long harness runs. IC Role / Device Role / Timing Role: Primary overvoltage clamp ahead of LDO regulators and PMIC inputs, sized to absorb repetitive transients from adjacent switching loads. Use Value: Withstands ≥1000 cycles of 40 V/100 ms transients (per AEC-Q101 stress test) without parameter shift - ensuring field reliability over 15-year vehicle lifetime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMC17A-Q | Same VRWM (17 V), but higher VCL = 29.2 V at 20.5 A; 1.5× larger SMC package (7.1 mm × 6.2 mm). | Less suitable for space-constrained modules; better for high-energy industrial surge where board area is available. | Select when higher IPPM margin (>25 A) is needed and Z-height >2.2 mm is acceptable. |
| TPSMD17A | Identical VRWM and VCL specs, but not AEC-Q101 qualified; Rth(j-a) = 200 K/W vs. 12 K/W to solder point. | Restricted to non-automotive industrial or consumer applications; unsuitable for under-hood thermal environments. | Choose only for cost-sensitive non-automotive designs where AEC-Q101 compliance and thermal performance are not required. |
Compared with SMC17A-Q and TPSMD17A, PTVS17VP1UP-QX delivers superior thermal performance (12 K/W to solder point), AEC-Q101 validation for automotive deployment, and ultra-low 1 mm profile - making it the optimal choice for modern compact, high-reliability vehicle ECUs.

FAQ
What is the maximum clamping voltage of PTVS17VP1UP-QX at its rated peak pulse current?
The maximum clamping voltage (VCL) is 27.6 V at 21.7 A peak pulse current (IPPM), measured per IEC 61643-321 (10/1000 µs waveform) at Tj = 25 °C. This value is confirmed in Table 8 of the official Nexperia datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case transients.
Is PTVS17VP1UP-QX suitable for bidirectional signal lines like RS-485 or USB?
No - PTVS17VP1UP-QX is unidirectional and conducts only in reverse breakdown. It must be used with anode grounded and cathode on the protected line. For bidirectional data lines, a symmetric TVS pair or dedicated bidirectional device (e.g., PTVS3V3S1UR) is required to protect both positive and negative excursions.
How does the 1 mm package height impact PCB layout and thermal design?
The 1 mm SOD128 (CFP5) height allows placement under connectors, shields, and tight enclosures common in automotive modules. Its low Rth(j-sp) = 12 K/W requires a minimum 1 cm² copper pour connected to the cathode pad - verified in Nexperia's thermal characterization (Table 6, condition [2]) - to maintain Tj ≤ 150 °C under full 600 W pulse loading.
Does PTVS17VP1UP-QX require derating for operation above 25 °C ambient?
Yes - peak pulse power derates linearly with junction temperature: at 125 °C, PPPM drops to ~400 W (Fig. 2). Designers must calculate worst-case Tj using Rth(j-a) = 60 K/W (ceramic PCB) or Rth(j-sp) = 12 K/W (FR4 with cathode pad), then apply appropriate safety margin for repetitive transients in under-hood environments.
