Product details
Overview
PTVS12VU1UPAZ from Nexperia is a unidirectional 300 W Transient Voltage Suppressor (TVS) in DFN2020-3 (SOT1061) package, designed for clamping overvoltage transients on DC power rails. It features 12 V reverse standoff voltage (VRWM), 14.0 V typical breakdown voltage (VBR), 1 nA reverse leakage at VRWM, 131 A peak pulse current (IPPM) under 10/1000 µs waveform, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the PTVS12VU1UPAZ datasheet, PTVS12VU1UPAZ pinout, PTVS12VU1UPAZ application, or PTVS12VU1UPAZ equivalent, key selection criteria include clamping voltage (15.1 V at 131 A), ultra-thin 0.65 mm profile, dual-anode single-cathode configuration, and IEC 61000-4-5/61643-321 compliance for industrial and automotive surge protection.
Technical Context
This unidirectional TVS diode operates as a clamping device-conducting only when reverse voltage exceeds VBR (13.3–14.7 V), with low dynamic impedance to limit transient energy. Its DFN2020-3 package integrates thermal enhancement via cathode pad, enabling 10 K/W junction-to-solder-point thermal resistance.
It delivers 300 W rated peak pulse power per IEC 61643-321 (10/1000 µs) and withstands up to 30 kV ESD per IEC 61000-4-2 (contact/air discharge), supporting robust front-end protection in space-constrained 12 V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 12 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum system rail tolerance margin. |
| VBR (typ) | 14.0 V - Voltage at 1 mA test current; defines onset of avalanche conduction during overvoltage events. |
| VCL @ IPPM | 15.1 V at 131 A - Clamped voltage during 10/1000 µs surge; determines maximum stress on downstream ICs. |
| PPPM | 300 W - Peak pulse power handling per IEC 61643-321; enables protection against common lightning-induced surges. |
| IRM | 1 nA - Reverse leakage at VRWM; ensures negligible standby power loss in battery-powered applications. |
| Package | DFN2020-3 (SOT1061) - 2.0 × 2.0 × 0.65 mm footprint; supports high-density PCB layouts and automated reflow assembly. |
| AEC-Q101 | Qualified - Meets automotive stress-test requirements for temperature cycling, HTRB, and ESD, enabling use in engine control and body electronics. |
Pinout & Package
DFN2020-3 (SOT1061) is a leadless, thermally enhanced plastic package with 3 terminals and 0.65 mm max height. Cathode connection is optimized for low-inductance, high-current surge dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 and 2 | Anode | Parallel-connected input terminals; provide low-inductance path for transient current into the diode junction. |
| 3 | Cathode | Common output terminal tied to ground or return path; sized for thermal dissipation and low-impedance surge sink. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 0.65 mm max height - Enables integration beneath shields or in ultra-thin modules without mechanical interference. |
| High ESD immunity | 30 kV contact/air discharge - Protects sensitive microcontrollers and CAN transceivers from human-body-model events. |
| Thermal performance | 10 K/W Rth(j-sp) - Ensures reliable operation under repeated surge conditions when mounted on standard FR4 with cathode pad. |
| Automotive qualification | AEC-Q101 compliant - Validated for temperature cycling, HTGB, and HTRB, supporting deployment in under-hood ECUs. |
| Low leakage | 1 nA IRM at 12 V - Minimizes quiescent current draw in always-on vehicle subsystems (e.g., alarm, telematics). |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A | DO-214AC package (4.5 × 2.7 × 2.2 mm); 400 W PPPM; 19.9 V VCL at 16.7 A; higher clamping voltage and larger footprint. | Used where board space is less constrained and higher surge margin is needed, but not suitable for AEC-Q101 automotive modules. | Select SMAJ12A only if thermal mass and legacy DO-214AC compatibility outweigh size and qualification requirements. |
| TPSMD12A | DO-214AB package (7.1 × 6.2 × 2.6 mm); 300 W PPPM; 19.0 V VCL at 15.8 A; non-automotive grade; lower ESD rating (16 kV). | Targeted at cost-sensitive industrial power supplies lacking automotive qualification mandates. | Choose TPSMD12A for non-automotive 12 V systems where footprint and ESD immunity are secondary to BOM cost. |
Compared with SMAJ12A and TPSMD12A, PTVS12VU1UPAZ offers superior space efficiency (75% smaller footprint), lower clamping voltage (15.1 V vs ≥19.0 V), and AEC-Q101 qualification-making it the only choice for next-generation automotive 12 V domain controllers requiring compact, qualified surge protection.

FAQ
What is the maximum clamping voltage of PTVS12VU1UPAZ under a 10/1000 µs surge?
The clamping voltage is 15.1 V at 131 A peak pulse current under the 10/1000 µs waveform per IEC 61643-321. This value is measured across pins 1&2 to pin 3 and represents the maximum voltage seen by downstream circuitry during worst-case surge events.
Can PTVS12VU1UPAZ be used in bidirectional configurations?
No-PTVS12VU1UPAZ is strictly unidirectional. Its internal structure connects pins 1 and 2 to the anode and pin 3 to the cathode. For bidirectional protection, two devices must be used in series opposition or a dedicated bidirectional TVS (e.g., PTVS12VU2UPAZ) should be selected.
Is the DFN2020-3 package compatible with standard reflow profiles?
Yes-the SOT1061 package is qualified for IPC/JEDEC J-STD-020D reflow profiles. Recommended solder paste stencil aperture is 0.4 mm thickness with 1.1 × 1.2 mm openings for pins 1/2 and 1.05 × 1.7 mm for cathode pad (pin 3), per Nexperia's footprint guide.
How does AEC-Q101 qualification impact PTVS12VU1UPAZ's use in non-automotive designs?
AEC-Q101 qualification confirms extended temperature operation (−55 °C to +150 °C), robust HTRB/HTGB performance, and ESD resilience-providing design margin for harsh industrial environments, even when automotive use is not required. It does not restrict usage outside automotive applications.
