Product details
Overview
PTVS12VP1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at 12 V nominal systems. It features VRWM = 12 V, VBR = 13.3–14.7 V (min–max), VCL = 19.9 V at IPPM = 30.2 A (10/1000 µs), and IRM ≤ 0.005 µA - enabling robust ESD and surge suppression in power rails of engine control units and body electronics.
For engineers reviewing the PTVS12VP1UP-QX datasheet, PTVS12VP1UP-QX pinout, PTVS12VP1UP-QX application, or PTVS12VP1UP-QX equivalent, key selection criteria include clamping voltage margin vs. 12 V system rail, AEC-Q101 qualification status, thermal resistance to solder point (Rth(j-sp) = 12 K/W), and low-profile 1 mm height for space-constrained automotive PCB layouts.
Technical Context
This unidirectional TVS diode operates as a shunt protector: under normal bias (VR ≤ 12 V), it presents <0.005 µA leakage; during transients exceeding VBR (~14.0 V typ), it avalanches to clamp voltage at 19.9 V while conducting up to 30.2 A peak pulse current per IEC 61643-321 (10/1000 µs). Its junction-to-solder-point thermal resistance of 12 K/W supports reliable power dissipation in high-density automotive modules.
Qualified to AEC-Q101, it withstands ±30 kV contact/air discharge (IEC 61000-4-2) and 8 kV HBM, with operating ambient range from −55 °C to +150 °C and junction limit of 150 °C - confirming suitability for under-hood and infotainment power supply protection where thermal cycling and ESD immunity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W - sustains 10/1000 µs surges without degradation in automotive load-dump or ISO 7637-2 transient events |
| Reverse Standoff Voltage (VRWM) | 12 V - maximum continuous reverse voltage before significant leakage; matches nominal 12 V vehicle battery systems |
| Breakdown Voltage (VBR) | 13.3–14.7 V - guaranteed avalanche onset range at 1 mA test current; ensures reliable triggering above system rail |
| Clamping Voltage (VCL) | 19.9 V at IPPM = 30.2 A - limits downstream IC voltage stress during worst-case surge, preserving 12 V logic and analog components |
| Reverse Leakage (IRM) | ≤0.005 µA at VRWM - negligible standby power loss in always-on automotive circuits (e.g., CAN wake-up lines) |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact/air), 8 kV HBM - exceeds automotive EMC requirements for human interaction points |
| Package | SOD128 (CFP5) - 3.8 × 2.6 × 1.0 mm surface-mount outline with 4 mm lead pitch; enables high-density placement near connectors |
Pinout & Package
SOD128 (CFP5) plastic surface-mounted package: 2-terminal, flat-lead, 1 mm profile; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 12 V rail); avalanche conduction occurs from anode to cathode during overvoltage |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance shunt path to divert surge current away from sensitive loads |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test standard - eliminates need for additional qualification in Tier 1 BOMs |
| 1 mm package height | Enables stacking under shields or integration into ultra-thin ECUs without mechanical interference |
| Junction-to-solder-point Rth | 12 K/W - enables efficient heat transfer to PCB copper, supporting repeated surge handling in compact layouts |
| Low IRM leakage | ≤0.005 µA at 12 V - prevents battery drain in always-on vehicle subsystems (e.g., telematics, alarm controllers) |
| High ESD immunity | ±30 kV contact discharge - protects against assembly-line ESD and field-level electrostatic events in service environments |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Infotainment Display Supply |
|---|---|

Use Scenario: Protects 12 V input rail of gasoline/diesel ECU against load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Shunt TVS diode placed upstream of DC-DC converter input, clamping transients before they reach regulator ICs. Use Value: VCL = 19.9 V ensures downstream 24 V-rated input capacitors and LDOs remain within safe operating area during 100 V/100 ms surges. |
Use Scenario: Shields 12 V backlight and interface power of TFT display module from ignition noise and cable coupling. IC Role / Device Role / Timing Role: Unidirectional TVS connected between display power rail and chassis ground, triggered only on positive overvoltage. Use Value: 1 mm height allows placement directly at FPC connector entry point, minimizing inductance and improving clamping response time. |
| Body Control Module (BCM) LIN Bus Line | ADAS Camera Power Rail |
|
Use Scenario: Guards LIN transceiver VCC supply against battery disconnection spikes and relay switching noise. IC Role / Device Role / Timing Role: Low-leakage TVS (IRM ≤ 0.005 µA) placed adjacent to LIN IC power pin to avoid signal distortion. Use Value: VRWM = 12 V avoids false triggering during normal 12 V battery fluctuations while maintaining fast response to >14 V transients. |
Use Scenario: Safeguards 12 V input of image sensor module against ESD from lens housing and vibration-induced cable arcs. IC Role / Device Role / Timing Role: AEC-Q101-qualified TVS mounted at camera board edge connector, providing first-line defense before PMIC. Use Value: ±30 kV ESD rating meets ISO 10605 requirements for external-facing ADAS sensors exposed to human touch and environmental charge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A-Q | 400 W PPPM, SMA package (2.4 mm height), VRWM = 12 V, VCL = 19.9 V at 21.6 A | Lower surge rating; unsuitable for full ISO 7637-2 Pulse 5a compliance in high-energy ECUs | Select when cost sensitivity outweighs peak energy requirement and board height allows SMA footprint |
| TPSMF12A | 600 W PPPM, SOD-123FL package (1.1 mm height), VRWM = 12 V, VCL = 19.2 V at 31.3 A | Similar clamping but higher IPPM; lacks AEC-Q101 certification and has lower ESD rating (±25 kV) | Prefer for non-automotive industrial 12 V systems where AEC qualification is not mandated |
Compared with SMAJ12A-Q and TPSMF12A, PTVS12VP1UP-QX uniquely combines AEC-Q101 qualification, 1 mm profile, ±30 kV ESD immunity, and verified 600 W surge capability - making it the only choice for space-constrained, safety-critical automotive power rail protection requiring full ISO 7637-2 and IEC 61000-4-2 compliance.

FAQ
What is the maximum clamping voltage of PTVS12VP1UP-QX under a 10/1000 µs surge?
The clamping voltage (VCL) is 19.9 V at rated peak pulse current (IPPM) of 30.2 A, measured per IEC 61643-321. This value is guaranteed across temperature and represents the maximum voltage seen by downstream circuitry during worst-case surge events.
Does PTVS12VP1UP-QX require a heatsink for 600 W surge handling?
No external heatsink is required. With Rth(j-sp) = 12 K/W and a standard FR4 PCB footprint, the device dissipates surge energy through the cathode solder joint into the PCB copper. Thermal performance is validated for single-pulse 600 W events without derating in automotive ambient conditions.
Can PTVS12VP1UP-QX be used in bidirectional protection configurations?
No - it is a unidirectional TVS diode. Its anode must be tied to ground and cathode to the protected line. For bidirectional protection (e.g., data lines), a separate symmetric TVS like PTVS3V3S1UR-QX or dual-diode array is required.
How does the marking code 'AV' correspond to PTVS12VP1UP-QX?
'AV' is the top-side laser marking for PTVS12VP1UP-QX per Nexperia's ordering table. It appears adjacent to the cathode bar on the SOD128 package and is used for visual identification and traceability during automated optical inspection and manual verification.
