Product details
Overview
PTVS7V5U1UPAZ 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 7.5 V reverse standoff voltage (VRWM), 8.33–9.21 V breakdown voltage (VBR), 12.9 V clamping voltage at 1000 A (8/20 µs), <1 nA reverse leakage at VRWM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PTVS7V5U1UPAZ datasheet, PTVS7V5U1UPAZ pinout, PTVS7V5U1UPAZ application, or PTVS7V5U1UPAZ equivalent, this device is selected for robust ESD and surge protection in space-constrained, high-reliability 12 V automotive subsystems, industrial power supplies, and low-voltage I/O interfaces where sub-millimeter height (<0.65 mm) and thermal resistance as low as 10 K/W (junction-to-solder point) are critical.
Technical Context
This unidirectional TVS operates as a silicon avalanche diode, triggered when reverse voltage exceeds its specified VRWM of 7.5 V and clamping within 12.9 V at 1000 A (8/20 µs). Its dual-anode (pins 1 & 2), single-cathode (pin 3) configuration enables low-inductance placement directly across protected lines and ground.
Rated for 300 W peak pulse power per IEC 61643-321 (10/1000 µs) and 3000 W under IEC 61000-4-5 (8/20 µs), it delivers 30 kV ESD immunity (IEC 61000-4-2 contact/air discharge) and maintains stable performance up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 300 W (10/1000 µs); sustains repeated transients in automotive load-dump and ISO 7637-2 environments |
| Reverse Standoff Voltage (VRWM) | 7.5 V; maximum continuous DC operating voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 8.33–9.21 V at 1 mA; precise avalanche initiation threshold ensures predictable clamping onset |
| Clamping Voltage (VCL) | 12.9 V at 1000 A (8/20 µs); limits downstream IC stress during high-energy surges |
| Reverse Leakage (IRM) | <1 nA at 7.5 V; negligible standby current draw in battery-powered systems |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact/air); protects against human-body-model and system-level ESD events |
| Package Height | 0.65 mm max; enables integration into ultra-thin modules and PCBs with tight Z-axis constraints |
| AEC-Q101 Qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress |
Pinout & Package
DFN2020-3 (SOT1061) is a leadless, thermally enhanced plastic package measuring 2.0 × 2.0 × 0.65 mm with exposed cathode pad for low thermal resistance (Rth(j-sp) = 10 K/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 and 2 | Anode | Dual-anode configuration reduces series inductance; connects to line being protected (e.g., +12 V rail) |
| 3 | Cathode | Exposed thermal pad and electrical cathode; must be soldered to large copper pour for optimal heat dissipation and low-clamp impedance |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 0.65 mm height enables use in slim automotive ECUs and portable industrial sensors |
| AEC-Q101 qualification | Validated for automotive under-hood and infotainment applications per stress test requirements |
| High ESD immunity | ±30 kV contact/air discharge rating eliminates need for additional ESD stages in front-end protection |
| Low clamping voltage | 12.9 V at 1000 A ensures safe operation of 13.5 V-rated downstream components during surge events |
| Thermal enhancement | 10 K/W junction-to-solder-point resistance allows sustained 300 W pulses without derating on standard FR4 |
Applications
| Automotive Body Control Module (BCM) | Industrial 24 V PLC Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | DO-214AC package (4.5 × 2.7 × 2.2 mm); 400 W PPPM; higher clamping (12.4 V @ 32.4 A); no AEC-Q101 | Higher profile and lower surge current rating; suitable for non-automotive consumer power supplies | Select when board space permits larger footprint and AEC-Q101 is not required |
| TPSMD7.5 | SMC package (7.1 × 6.2 × 2.6 mm); 1500 W PPPM; 12.5 V clamping @ 120 A; AEC-Q101 qualified | Higher power handling but 4× larger volume; used where multi-kilowatt surge immunity is needed | Select when protecting high-current 12 V buses subject to ISO 16750-2 severe transients |
Compared with SMAJ7.5A and TPSMD7.5, PTVS7V5U1UPAZ offers the smallest footprint and lowest profile among AEC-Q101-qualified 7.5 V TVS diodes, enabling protection in space-limited automotive modules where thermal resistance below 15 K/W and ESD immunity ≥30 kV are mandatory design criteria.

FAQ
What is the maximum operating temperature for PTVS7V5U1UPAZ?
The device supports continuous operation up to +150 °C junction temperature, with thermal resistance from junction to solder point rated at 10 K/W. This enables reliable performance in under-hood automotive environments and enclosed industrial enclosures without active cooling, provided the cathode pad is soldered to ≥1 cm² copper area per Nexperia's recommended layout.
Can PTVS7V5U1UPAZ be used for bidirectional protection?
No - PTVS7V5U1UPAZ is strictly unidirectional, with anode (pins 1 & 2) and cathode (pin 3) terminals. It conducts only during reverse-biased overvoltage events. For bidirectional protection, Nexperia's PTVS7V5S1UPAZ (symmetrical) or discrete back-to-back diode configurations are required.
How does the 0.65 mm package height impact PCB assembly?
The DFN2020-3 package requires precise stencil aperture design (0.4 mm thickness, 0.55 × 0.6 mm openings) and reflow profile control to ensure void-free solder joints on the exposed cathode pad. Its low height eliminates mechanical interference in stacked-board assemblies but demands X-ray inspection for solder joint quality verification.
Is PTVS7V5U1UPAZ compatible with lead-free reflow processes?
Yes - the device is qualified for standard lead-free reflow per JEDEC J-STD-020, with peak temperature tolerance up to 260 °C for 30 seconds. The SOT1061 package uses matte tin plating and passes MSL1 classification, eliminating pre-bake requirements and supporting high-yield automated assembly.
