Product details
Overview
PTVS30VS1UR-Q from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) diode in SOD123W (CFP3) package, designed for automotive-grade overvoltage protection. It features 30 V reverse standoff voltage (VRWM), 35.1 V typical breakdown voltage (VBR), 48.4 V clamping voltage (VCL) at 8.3 A peak pulse current, and <0.1 µA reverse leakage at VRWM - deployed in 12 V automotive power rail protection.
For engineers reviewing the PTVS30VS1UR-Q datasheet, PTVS30VS1UR-Q pinout, PTVS30VS1UR-Q application, or PTVS30VS1UR-Q equivalent, this device is selected for high-reliability transient suppression in AEC-Q101-compliant systems where low-profile mounting, fast response (<1 ns), and IEC 61643-321 (10/1000 µs) compliance are critical.
Technical Context
This unidirectional TVS operates as a clamping device in series with the protected line, conducting only during overvoltage events above its breakdown threshold. Its silicon avalanche structure delivers sub-nanosecond response time and handles 400 W peak pulse power per IEC 61643-321 (10/1000 µs waveform).
Thermal design relies on low junction-to-solder-point thermal resistance (18 K/W) and supports operation up to 150 °C junction temperature. Qualified to AEC-Q101, it meets automotive ESD requirements including ±30 kV contact discharge (IEC 61000-4-2) and 8 kV HBM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 30 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (typ) | 35.1 V at 1 mA - precise avalanche onset ensures predictable protection threshold |
| VCL @ IPPM | 48.4 V at 8.3 A - limits downstream voltage stress during 400 W transient events |
| PPPM | 400 W - peak pulse power handling per IEC 61643-321 10/1000 µs waveform |
| IRM | 0.1 µA max at VRWM - negligible leakage preserves system standby current budget |
| Package | SOD123W (CFP3) - 2.6 × 1.7 × 1.0 mm surface-mount footprint with 1 mm height for space-constrained PCBs |
| AEC-Q101 | Qualified - validated for automotive underhood and infotainment applications per stress test standard |
Pinout & Package
SOD123W (CFP3) is a 2-terminal, flat-lead surface-mount plastic package with cathode-marked top-side bar. Total body dimensions: 2.6 mm × 1.7 mm × 1.0 mm; recommended reflow solder land: 1.2 mm × 2.1 mm per pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 12 V rail); marking bar identifies this terminal |
| 2 (A) | Anode | Connected to ground reference; forms clamping path during overvoltage transients |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SMD package | 1.0 mm height enables use in ultra-thin automotive ECUs and ADAS modules |
| AEC-Q101 qualification | Validated for automotive temperature range (−55 °C to +150 °C) and mechanical stress |
| High ESD robustness | ±30 kV contact discharge rating eliminates need for external ESD staging in CAN/LIN interfaces |
| Precision clamping window | 30 V VRWM → 48.4 V VCL gives 18.4 V clamping margin - sufficient headroom for 12 V system load dump peaks |
| Thermal performance | 18 K/W junction-to-solder-point resistance allows direct thermal coupling to copper pour without heatsink |
Applications
| Automotive Power Rail Protection | CAN Bus Transceiver Protection |
|---|---|
Use Scenario: Protecting 12 V battery-supplied microcontroller power inputs against ISO 7637-2 load dump pulses (up to 60 V, 100 ms). IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between VCC and GND, activated within <1 ns of overvoltage onset. Use Value: Limits voltage to ≤48.4 V during 400 W transients, preventing brownout or latch-up in MCU and PMIC devices. | Use Scenario: Safeguarding high-speed CAN FD transceivers (e.g., TJA1044) from ESD and coupled surges on differential bus lines. IC Role / Device Role / Timing Role: Single-line unidirectional TVS on CAN_H or CAN_L line, referenced to ground. Use Value: Withstands ±30 kV contact ESD per IEC 61000-4-2 while maintaining signal integrity due to low capacitance (<100 pF typical). |
| Industrial Sensor Interface Protection | Body Control Module (BCM) Input Protection |
Use Scenario: Shielding analog sensor inputs (e.g., pressure, temperature) in harsh industrial environments subject to inductive switching noise. IC Role / Device Role / Timing Role: Low-leakage TVS on signal line to ground, preserving DC accuracy and dynamic range. Use Value: 0.1 µA IRM at 30 V ensures minimal offset error in 24 V sensor bridges and 4–20 mA loop receivers. | Use Scenario: Guarding discrete input pins (e.g., door lock switch, trunk release) in BCM against cable discharge and relay flyback. IC Role / Device Role / Timing Role: Point-of-entry TVS on each switch input, mounted adjacent to connector. Use Value: 400 W PPPM rating absorbs repetitive 100 V/100 ms transients common in 12 V vehicle subsystems without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A-Q | Same VRWM (30 V), but SMA package (4.5 × 2.7 × 2.2 mm); 400 W PPPM; higher VCL (48.9 V) | Larger footprint and 2.2 mm height limit use in ultra-low-profile automotive modules | Select when board space permits and legacy SMA layout reuse is prioritized |
| TPSMA6L30A-Q | Same VRWM and SOD123W package; lower PPPM (300 W); VCL = 48.4 V; AEC-Q101 qualified | Reduced surge margin for severe load dump scenarios per ISO 7637-2 Pulse 5a | Choose for cost-sensitive applications with verified 300 W transient exposure |
Compared with SMAJ30A-Q and TPSMA6L30A-Q, PTVS30VS1UR-Q uniquely combines AEC-Q101 qualification, 400 W rating, and 1.0 mm profile in SOD123W - making it optimal for next-gen compact automotive ECUs requiring full-spec surge immunity.

FAQ
What is the maximum clamping voltage of PTVS30VS1UR-Q at rated peak pulse current?
The clamping voltage (VCL) is 48.4 V at 8.3 A peak pulse current (IPPM), measured per IEC 61643-321 10/1000 µs waveform. This value is guaranteed maximum per datasheet Table 8 and defines the upper voltage limit imposed on protected circuitry during worst-case transients.
Does PTVS30VS1UR-Q support bidirectional transient suppression?
No - PTVS30VS1UR-Q is a unidirectional TVS diode, configured for protection against positive-going transients only (anode grounded, cathode on protected line). For bidirectional protection, two devices in series opposition or a dedicated bidirectional part like PTVS30VS1UR-S would be required.
How does the SOD123W package affect thermal performance compared to SMA?
The SOD123W package achieves 18 K/W junction-to-solder-point thermal resistance - significantly lower than SMA's ~40 K/W - due to its flat lead construction and direct thermal path through cathode tab. This enables higher sustained surge duty cycles without derating in dense automotive PCB layouts.
Is PTVS30VS1UR-Q 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. The recommended reflow footprint (1.2 mm × 2.1 mm pads, 0.1 mm stencil) ensures reliable solder joint formation and avoids tombstoning in automated assembly.
