Product details
Overview
PTVS6V5P1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at the board level. It features a 6.5 V reverse standoff voltage (VRWM), 7.60 V typical breakdown voltage (VBR), 11.2 V clamping voltage (VCL) at 250 A peak pulse current, and is qualified to AEC-Q101 for under-hood power rail and sensor interface protection.
For engineers reviewing the PTVS6V5P1UP-QX datasheet, PTVS6V5P1UP-QX pinout, PTVS6V5P1UP-QX application, or PTVS6V5P1UP-QX equivalent, key selection criteria include clamping performance under IEC 61643-321 10/1000 µs waveform, low leakage (<5 µA at VRWM), thermal resistance to solder point (12 K/W), and AEC-Q101 qualification status for automotive deployment.
Technical Context
This TVS diode operates as a unidirectional shunt protector: it remains high-impedance below VRWM = 6.5 V, then rapidly avalanches above VBR = 7.22–7.98 V to clamp transients. Its junction-to-solder-point thermal resistance of 12 K/W enables effective heat dissipation during 600 W peak pulses.
The device uses silicon planar technology with controlled avalanche characteristics, supports 30 kV ESD (IEC 61000-4-2 contact/air), and maintains stable clamping up to 150 °C junction temperature - critical for engine control unit (ECU) and body electronics applications where ambient temperatures exceed 105 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W per IEC 61643-321 (10/1000 µs); sustains high-energy load dump surges without failure |
| Reverse Standoff Voltage (VRWM) | 6.5 V; maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 7.22–7.98 V at IR = 1 mA; defines onset of controlled avalanche conduction |
| Clamping Voltage (VCL) | 11.2 V at IPPM = 250 A; limits transient voltage seen by downstream ICs during surge events |
| Reverse Leakage (IRM) | ≤5 µA at VRWM; ensures minimal quiescent current draw in battery-sensitive systems |
| ESD Rating | 30 kV contact / 30 kV air (IEC 61000-4-2); protects against human-body and system-level electrostatic discharge |
| Junction Temp Limit (Tj) | 150 °C max; enables operation in under-hood environments with sustained high ambient temperatures |
Pinout & Package
PTVS6V5P1UP-QX is housed in a compact SOD128 (CFP5) surface-mount plastic package measuring 3.8 mm × 2.6 mm × 1.0 mm, with 2 terminals and 4 mm pitch. The cathode is marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 12 V rail); conducts surge current to ground when clamped |
| 2 (A) | Anode | Connected to system ground; completes low-inductance path for transient energy dissipation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, HTRB, and ESD stress per discrete semiconductor standard |
| Low-profile SOD128 package | 1.0 mm height enables placement under connectors or in space-constrained ECUs without mechanical interference |
| 600 W peak pulse rating | Withstands ISO 7637-2 Pulse 5a (load dump) surges up to 60 V/100 ms without degradation |
| Sub-12 V clamping at 250 A | Protects 5 V and 3.3 V logic interfaces powered from regulated 12 V rails (e.g., CAN transceivers, LIN controllers) |
| 30 kV ESD robustness | Eliminates need for additional ESD protection on exposed ports like OBD-II or sensor harnesses |
Applications
| Automotive Power Rail Protection | Body Control Module (BCM) Input Protection |
|---|---|
Use Scenario: Protecting 12 V supply lines in engine control units against load dump transients per ISO 7637-2. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between battery rail and local regulator input. Use Value: Clamps 60 V/100 ms load dump to ≤11.2 V, preventing regulator latch-up or MOSFET gate oxide damage. |
Use Scenario: Safeguarding BCM microcontroller GPIOs connected to door lock actuators or window switches. IC Role / Device Role / Timing Role: Localized transient suppressor mounted directly at connector entry point. Use Value: Limits induced switching spikes (<100 ns rise time) to <12 V, avoiding false wake-up or latch-up in 3.3 V I/O cells. |
| CAN Bus Physical Layer Protection | Industrial Sensor Interface Protection |
Use Scenario: Shielding high-speed CAN FD transceivers (e.g., TJA1044) from ESD and cable discharge events. IC Role / Device Role / Timing Role: Bidirectional-capable protection (used unidirectionally with ground-referenced layout) on CAN_H/CAN_L lines. Use Value: 30 kV ESD immunity and 11.2 V clamping preserve signal integrity while meeting ISO 11898-2 EMC requirements. |
Use Scenario: Guarding 4–20 mA loop-powered pressure/temperature sensors in factory automation cabinets. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 24 V loop supply input before precision ADC front-end. Use Value: Prevents >12 V transients from saturating op-amp stages or damaging current-sense resistors in analog signal chains. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.5A-Q | Same VRWM (6.5 V) but lower PPPM (400 W); higher VCL (11.5 V at 23.9 A) | Limited to lower-energy transients (e.g., ISO 7637-2 Pulse 1/2); not suitable for load dump | Select only if surge energy is confirmed <400 W and board space allows SMA package |
| TPSMD6.5A | Higher VRWM tolerance (6.5 V min, 7.22 V typ); identical VCL (11.2 V) but rated for 600 W at 25 °C only | Derates faster above 85 °C; lacks AEC-Q101 certification for automotive production | Acceptable for industrial use with active thermal management, but not for automotive OEM programs |
Compared with SMAJ6.5A-Q and TPSMD6.5A, PTVS6V5P1UP-QX delivers superior thermal stability (12 K/W Rth(j-sp)), guaranteed AEC-Q101 compliance, and consistent 600 W capability across full automotive temperature range - making it the only choice for production-critical 12 V rail protection.

FAQ
What is the maximum clamping voltage of PTVS6V5P1UP-QX under surge conditions?
The clamping voltage is 11.2 V at 250 A peak pulse current (IPPM), measured per IEC 61643-321 10/1000 µs waveform. This value is guaranteed across the full operating temperature range (−55 °C to 150 °C) and ensures downstream 5 V or 3.3 V ICs remain within absolute maximum ratings during transient events.
Is PTVS6V5P1UP-QX suitable for bidirectional transient protection?
No - it is a unidirectional TVS diode, optimized for DC-biased lines like 12 V automotive rails. For bidirectional protection (e.g., data lines), a symmetric device such as PTVS3V3S1UR-QX would be required. Using this part in reverse-biased configuration risks permanent damage due to forward conduction.
How does the SOD128 package affect thermal performance in high-power surge events?
The SOD128 package achieves a junction-to-solder-point thermal resistance of 12 K/W, enabling rapid heat transfer to the PCB copper pour. This allows the device to sustain repeated 600 W pulses without exceeding 150 °C junction temperature - a key advantage over larger packages with higher Rth(j-sp) in constrained ECU layouts.
Does PTVS6V5P1UP-QX require external current limiting for normal operation?
No - it draws only ≤5 µA reverse leakage at 6.5 V VRWM, eliminating the need for series resistors in standby mode. Unlike Zener-based protectors, it exhibits no steady-state power dissipation until clamping occurs, making it ideal for always-on automotive modules with strict quiescent current budgets.
