Product details
Overview
PTVS30VS1UTR-Q from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature overvoltage protection in automotive power rails. It features VRWM = 30 V, VBR(min) = 33.3 V, clamping voltage VCL = 48.4 V at IPPM = 8.3 A (10/1000 µs), and junction temperature rating up to 185 °C.
For engineers reviewing the PTVS30VS1UTR-Q datasheet, PTVS30VS1UTR-Q pinout, PTVS30VS1UTR-Q application, or PTVS30VS1UTR-Q equivalent, key selection criteria include peak pulse power derating above 25 °C, cathode-anode polarity alignment in PCB layout, clamping performance under ISO 7637-2 pulse 1/2a/5a, and AEC-Q101 qualification for under-hood deployment.
Technical Context
This TVS diode operates as a unidirectional clamping device with avalanche breakdown behavior. Its I-V characteristic follows a sharp knee at VBR ≈ 35.1 V (typ), delivering stable clamping at VCL = 48.4 V under 8.3 A transient current per IEC 61643-321 (10/1000 µs).
Thermal design relies on low Rth(j-sp) = 18 K/W to solder point and rated operation up to Tj = 185 °C, enabled by optimized die attach and SOD123W copper leadframe construction. ESD robustness includes ±30 kV contact discharge per IEC 61000-4-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 30 V - Maximum continuous reverse operating voltage before leakage exceeds 0.1 µA at 25 °C |
| VBR (min) | 33.3 V - Minimum breakdown voltage at 1 mA test current, ensuring reliable turn-on during transients |
| VCL @ IPPM | 48.4 V - Clamping voltage at 8.3 A peak pulse current, defining maximum protected-line voltage excursion |
| PPPM | 400 W - Peak pulse power handling capability under 10/1000 µs waveform, derated above 25 °C |
| IRM | 0.001 µA - Reverse leakage at VRWM, critical for low-power standby circuit integrity |
| Tj max | 185 °C - Maximum junction temperature, enabling placement near hot components like power converters |
| ESD Rating | ±30 kV - Contact discharge immunity per IEC 61000-4-2, eliminating need for external ESD staging |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body height, flat leads, cathode-marked bar, optimized for automated reflow and wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 12 V rail); marking bar identifies this terminal for correct orientation |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance shunt path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including engine control units, body electronics, and ADAS power domains |
| High-temperature operation | Full 400 W pulse rating maintained up to 150 °C ambient; usable at Tj = 185 °C with appropriate derating |
| Low-profile SOD123W | 1.0 mm max height enables placement under shields or in space-constrained modules such as battery management systems |
| Low IRM leakage | ≤0.001 µA at VRWM minimizes quiescent current drain in always-on vehicle networks (e.g., CAN standby) |
| IEC 61643-321 compliance | Tested to 10/1000 µs waveform ensures compatibility with ISO 7637-2 transient immunity requirements |
Applications
| Automotive Power Rail Protection | Industrial DC Power Input |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs against load dump and alternator surge per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between power input and ground, responding within nanoseconds to suppress >100 V transients. Use Value: Limits rail voltage to ≤48.4 V during 8.3 A surges, preventing damage to downstream LDOs, MCUs, and CAN transceivers. |
Use Scenario: Safeguarding programmable logic controller (PLC) 24 V DC inputs exposed to inductive switching noise in factory automation. IC Role / Device Role / Timing Role: Fast-acting overvoltage clamp on field-side power entry, absorbing repetitive 100 ns–1 ms spikes from solenoid drivers. Use Value: Maintains system uptime by preventing latch-up or gate oxide rupture in industrial-grade microcontrollers and analog front-ends. |
| High-Temperature Motor Drive Interface | On-Board Charger (OBC) Auxiliary Supply |
Use Scenario: Shielding gate driver bias supplies in EV traction inverters where ambient temperatures exceed 125 °C near power modules. IC Role / Device Role / Timing Role: High-Tj TVS mounted adjacent to isolated DC/DC converter outputs, clamping coupling transients from IGBT switching. Use Value: Enables reliable operation at junction temperatures up to 185 °C without thermal shutdown or parameter drift. |
Use Scenario: Protecting 12 V auxiliary supply lines in electric vehicle on-board chargers subjected to repeated cold-crank and jump-start events. IC Role / Device Role / Timing Role: Primary overvoltage suppression stage upstream of buck regulators powering communication ICs and sensors. Use Value: Withstands ≥400 W pulses while maintaining <1 µA leakage, preserving efficiency and meeting ASIL-B functional safety constraints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | Lower PPPM = 400 W but only rated to Tj = 150 °C; VCL = 48.4 V same, but IRM = 1 µA (1000× higher) | Not AEC-Q101 qualified; suitable for commercial industrial use but not automotive under-hood | Select when cost sensitivity outweighs automotive qualification and high-temp stability needs |
| TPSMD30A | Same VRWM/VCL, but larger SMA package (2.8 mm height); Tj = 175 °C; AEC-Q101 qualified | Higher thermal mass improves energy absorption in long-duration transients but increases board area | Prefer when PCB layout allows larger footprint and system requires marginally higher thermal endurance |
Compared with SMAJ30A and TPSMD30A, PTVS30VS1UTR-Q uniquely combines AEC-Q101 qualification, 185 °C junction rating, and 1.0 mm profile-making it optimal for space- and temperature-constrained automotive modules where leakage and reliability are non-negotiable.

FAQ
What is the clamping voltage of PTVS30VS1UTR-Q under standard test conditions?
The clamping voltage VCL is 48.4 V measured at IPPM = 8.3 A using the 10/1000 µs current waveform per IEC 61643-321. This value is guaranteed across the full operating temperature range and defines the maximum voltage seen by downstream circuitry during transient events.
Does PTVS30VS1UTR-Q require orientation-specific PCB layout?
Yes - the cathode (pin 1, marked by a bar) must be connected to the protected line (e.g., 12 V rail), and the anode (pin 2) to ground. Reversal prevents clamping action and leaves circuits unprotected; the SOD123W outline in Figure 5 confirms cathode-first orientation.
How does peak pulse power derate with temperature?
PPPM decreases linearly above 25 °C, reaching ~70 % of 400 W at 125 °C and ~50 % at 150 °C (per Fig. 2). Full 400 W is usable only at Tj ≤ 25 °C; design must account for ambient + self-heating to avoid exceeding 185 °C junction limit.
Is PTVS30VS1UTR-Q compatible with lead-free reflow processes?
Yes - it is qualified for standard lead-free reflow profiles (JEDEC J-STD-020), with peak temperature up to 260 °C. The recommended solder land pattern (Fig. 6) uses 0.1 mm stencil thickness and 1.2 mm × 1.4 mm pads for optimal wetting and void control.
