Product details
Overview
PTVS10VU1UPAZ from Nexperia is a unidirectional 300 W Transient Voltage Suppressor (TVS) in DFN2020-3 (SOT1061) package, designed for clamping transient overvoltages on DC power rails and signal lines. It features a 10 V reverse standoff voltage (VRWM), 12.3 V maximum breakdown voltage (VBR), 17.0 V clamping voltage at 50 A (VCL), 1 nA reverse leakage at VRWM, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the PTVS10VU1UPAZ datasheet, PTVS10VU1UPAZ pinout, PTVS10VU1UPAZ application, or PTVS10VU1UPAZ equivalent, key selection criteria include clamping performance under IEC 61000-4-5 (8/20 µs) and IEC 61643-321 (10/1000 µs) waveforms, thermal resistance to solder point (10 K/W), ultra-thin 0.65 mm profile, and unidirectional polarity configuration for positive-rail protection.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping device that remains high-impedance below VRWM = 10 V and rapidly transitions to low-impedance conduction above VBR = 11.1–12.3 V to divert surge current. Its junction-to-solder-point thermal resistance of 10 K/W enables effective heat dissipation into PCB copper during repetitive transients.
It complies with IEC 61000-4-5 (8/20 µs) and IEC 61643-321 (10/1000 µs) surge standards, delivering 50 A peak pulse current (IPPM) with 17.0 V clamping voltage and sustaining 300 W peak pulse power. The device is qualified to AEC-Q101, confirming robustness for automotive power rail and interface protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 300 W - Sustains single 10/1000 µs surges up to this energy level without failure |
| Reverse Standoff Voltage (VRWM) | 10 V - Maximum continuous DC voltage before significant leakage; sets operating margin for 12 V systems |
| Clamping Voltage (VCL) | 17.0 V at 50 A - Limits downstream IC voltage during 8/20 µs transients, protecting 16 V-rated components |
| Breakdown Voltage (VBR) | 11.1–12.3 V at 1 mA - Confirmed turn-on threshold ensuring reliable triggering before system damage |
| Reverse Leakage (IRM) | 2 nA at 10 V - Negligible standby current, critical for low-power always-on circuits |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact) - Withstands human-body-model ESD events without degradation |
| Package Height | 0.65 mm - Enables use in space-constrained automotive modules and portable electronics |
Pinout & Package
PTVS10VU1UPAZ uses the DFN2020-3 (SOT1061) leadless plastic package: 2.0 × 2.0 × 0.65 mm body, thermally enhanced cathode pad, no leads, and surface-mount construction optimized for automated assembly and thermal transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 and 2 | Anode | Connected together internally; tied to protected line (e.g., +12 V rail) in unidirectional configuration |
| 3 | Cathode | Connected to ground reference; serves as primary thermal path to PCB copper pour |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics per stress test requirements |
| Ultra-low profile (0.65 mm) | Enables integration into slim ECUs and ADAS modules where Z-height is constrained |
| Junction-to-solder-point Rth(j-sp) | 10 K/W - Direct thermal path to PCB improves surge survivability in repeated fault conditions |
| Low IRM (2 nA @ 10 V) | Minimizes quiescent power loss in battery-backed or energy-harvesting systems |
| DFN2020-3 footprint | Standardized land pattern supports reflow compatibility and manufacturability across contract manufacturers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | DO-214AC package (4.5 mm height), 400 W PPPM, 17.0 V VCL at 32.4 A | Larger footprint and height; lower current rating but higher surge energy handling | Select when board space allows larger package and higher single-pulse energy tolerance is required |
| SMF10A | SOD-123FL package (1.3 mm height), 200 W PPPM, 17.0 V VCL at 29.1 A | Lower power rating and taller profile than DFN2020-3; no AEC-Q101 qualification | Choose for cost-sensitive industrial designs where automotive qualification is not mandatory |
Compared with SMAJ10A and SMF10A, PTVS10VU1UPAZ offers the lowest profile (0.65 mm), AEC-Q101 qualification, and optimal thermal resistance (10 K/W to solder point), making it preferred for space- and reliability-critical automotive and portable applications despite identical clamping voltage.

FAQ
What is the maximum clamping voltage of PTVS10VU1UPAZ under IEC 61000-4-5 surge conditions?
The clamping voltage is 17.0 V at 50 A peak pulse current (IPPM) under 8/20 µs waveform per IEC 61000-4-5. This value is measured with the device mounted on standard FR4 PCB and represents worst-case voltage seen by downstream circuitry during surge events.
Can PTVS10VU1UPAZ be used in bidirectional configurations?
No - PTVS10VU1UPAZ is strictly unidirectional, with pins 1 and 2 as anode and pin 3 as cathode. For bidirectional protection, Nexperia offers the PTVS10VU1UPAZ's counterpart in the PTVS10VU1UPA series' dual-diode variant, or discrete back-to-back placement is required.
How does the DFN2020-3 package affect thermal performance compared to SMA or SOD packages?
The DFN2020-3 package delivers 10 K/W junction-to-solder-point thermal resistance - significantly lower than SMA (≈30 K/W) or SOD-123FL (≈50 K/W) - due to its exposed cathode pad and direct copper interface, enabling higher surge repetition rates without thermal runaway.
Is PTVS10VU1UPAZ compatible with lead-free reflow profiles?
Yes - the device is qualified for standard JEDEC J-STD-020D lead-free reflow, with peak temperature up to 260 °C. The recommended footprint matches Nexperia's SOT1061 layout, including 0.55 mm pad width and 1.05 mm center-to-center spacing for reliable solder joint formation.
