Product details
Overview
PTVS17VP1UTP-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 17 V reverse standoff voltage (VRWM), 27.6 V clamping voltage (VCL) at 5 mA, 21.7 A peak pulse current (IPPM), and junction temperature rating up to 185 °C.
For engineers reviewing the PTVS17VP1UTP-QX datasheet, PTVS17VP1UTP-QX pinout, PTVS17VP1UTP-QX application, or PTVS17VP1UTP-QX equivalent, this device is selected for robust ESD/EMI suppression in engine control units, battery management systems, and under-hood electronics where thermal stability and AEC-Q101 compliance are mandatory.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below VRWM = 17 V, then avalanches sharply at VBR ≈ 18.9–20.9 V to clamp transients. Its IEC 61643-321 (10/1000 µs) waveform compliance ensures standardized surge immunity testing.
Thermal design is enabled by low Rth(j-sp) = 12 K/W to solder point and rated operation up to Tamb = 185 °C ambient. The cathode-marked SOD128 package supports automated reflow with defined footprint per Fig. 7, and achieves 30 kV IEC 61000-4-2 contact discharge ESD tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - sustains 10/1000 µs surges without failure per IEC 61643-321 |
| Reverse Standoff Voltage | VRWM = 17 V - maximum continuous DC operating voltage before leakage exceeds 1 µA |
| Clamping Voltage | VCL = 27.6 V at IPPM = 21.7 A - limits transient voltage seen by protected IC during surge |
| Junction Temperature | Tj ≤ 185 °C - enables placement near heat sources in engine compartments |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2) - eliminates need for secondary ESD stages |
| AEC-Q101 Qualified | Qualified for automotive discrete semiconductors - meets stress test requirements for vibration, temperature cycling, and HBM |
Pinout & Package
SOD128 (CFP5) surface-mount plastic package: 2-terminal, 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm pitch, flat lead profile optimized for thermal dissipation and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected circuit's positive rail; marking bar identifies this terminal |
| 2 | Anode (A) | Connected to ground or low-impedance return path; completes clamping current loop during surge |
Key Features
| Feature | Design Value |
|---|---|
| High-Temperature Operation | Rated for continuous use at Tamb = –55 °C to +185 °C - suitable for under-hood and powertrain modules |
| Low Profile Height | 1.0 mm max - enables compact PCB layouts in space-constrained automotive ECUs |
| Automotive Qualification | AEC-Q101 qualified - validated for mechanical shock, temperature humidity bias, and accelerated life testing |
| Low Leakage Current | IRM ≤ 0.001 µA at VRWM - minimizes standby power loss in always-on vehicle networks |
| Robust Surge Handling | IPPM = 21.7 A at 10/1000 µs - protects against ISO 7637-2 Pulse 1, 2a, 3a/b, and ISO 16750-2 load dump surges |
Applications
| Engine Control Unit (ECU) Power Input | 12 V Battery Management System (BMS) |
|---|---|
Use Scenario: Protects microcontroller power supply from load dump and alternator ripple in gasoline/diesel engine bays. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between battery rail and LDO input to clamp transients before regulation. Use Value: Clamps 12 V system surges to ≤27.6 V, preventing latch-up or damage to 3.3 V/5 V logic supplies downstream. |
Use Scenario: Shields BMS analog front-end and cell monitoring ICs from jump-start spikes and grounding faults. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main 12 V input, upstream of DC-DC converters and current sense amplifiers. Use Value: Withstands 21.7 A peak pulses while maintaining <1 µA leakage, ensuring accuracy of millivolt-level voltage measurements. |
| Advanced Driver Assistance Systems (ADAS) Camera Module | Electric Power Steering (EPS) Motor Driver |
Use Scenario: Guards image sensor and serializer power lines against ESD events during vehicle assembly and service. IC Role / Device Role / Timing Role: Localized TVS at camera board edge connector, co-located with ferrite beads for combined ESD/EMI filtering. Use Value: 30 kV contact ESD rating eliminates need for external spark gaps; 1 mm height avoids interference with lens housing. |
Use Scenario: Suppresses inductive kickback from H-bridge MOSFET switching and motor commutation noise. IC Role / Device Role / Timing Role: Bidirectional clamping is not required; unidirectional PTVS17VP1UTP-QX placed across motor supply rail to ground. Use Value: 185 °C junction rating allows mounting directly on motor driver PCB near gate drivers without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ17A | Lower PPPM = 400 W; VRWM = 17 V; VCL = 27.7 V; Tj max = 150 °C; non-AEC-Q101 | Limited to under-dash infotainment or industrial controls - not qualified for powertrain or safety-critical zones | Select when cost sensitivity outweighs AEC-Q101 requirement and thermal margin is ≥35 °C lower |
| SMCJ17A-Q | Same VRWM/VCL; PPPM = 1500 W; larger SMC (DO-214AB) package; AEC-Q101 qualified; Rth(j-a) = 18 K/W | Better surge handling but 2.5× footprint and 2.2 mm height - unsuitable for ultra-thin ADAS modules | Select when system-level surge tests exceed IEC 61000-4-5 Level 4 and PCB area permits larger package |
Compared with SMAJ17A, PTVS17VP1UTP-QX delivers 50% higher surge power and full automotive qualification in half the height; versus SMCJ17A-Q, it trades 2.5× peak power for 60% smaller footprint and 55% lower profile - critical for modern compact ECU designs.

FAQ
What is the maximum clamping voltage of PTVS17VP1UTP-QX at its rated peak pulse current?
The clamping voltage VCL is 27.6 V at IPPM = 21.7 A, measured under IEC 61643-321 10/1000 µs waveform conditions. This value ensures protected downstream ICs experience no more than 27.6 V during worst-case surge events, preserving functional integrity of 3.3 V and 5 V logic rails.
Does PTVS17VP1UTP-QX require a heatsink for operation at 185 °C ambient?
No heatsink is required: the device is rated for continuous operation at Tamb = 185 °C when mounted per the recommended reflow footprint (Fig. 7). Its Rth(j-sp) = 12 K/W to solder point enables sufficient heat transfer through copper pads alone, provided PCB layout follows Nexperia's thermal guidelines for SOD128.
How does the marking code 'CM' identify PTVS17VP1UTP-QX on the device body?
The marking code 'CM' is laser-etched on the top surface of the SOD128 package and corresponds exclusively to PTVS17VP1UTP-QX per Table 4 of the datasheet. The cathode is indicated by a bar adjacent to pin 1, enabling unambiguous orientation during automated optical inspection and placement.
Can PTVS17VP1UTP-QX replace bidirectional TVS diodes in CAN bus protection circuits?
No - PTVS17VP1UTP-QX is unidirectional and only clamps positive transients relative to ground. CAN bus protection requires bidirectional clamping (e.g., PTVS3V3S1UR, PTVS5V0S1UR) to suppress both positive and negative line-to-line surges. Using this part on CAN would leave negative transients unprotected.
