Product details
Overview
PTVS13VS1UR-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 13 V reverse standoff voltage (VRWM), 21.5 V clamping voltage (VCL) at 18.6 A peak pulse current (IPPM), and 0.001 µA reverse leakage at VRWM - deployed in power supply rails and ECU front-end circuits.
For engineers reviewing the PTVS13VS1UR-Q datasheet, PTVS13VS1UR-Q pinout, PTVS13VS1UR-Q application, or PTVS13VS1UR-Q equivalent, key selection criteria include AEC-Q101 qualification, 1 mm profile for space-constrained PCBs, IEC 61643-321 (10/1000 µs) compliance, and cathode-anode polarity marking for correct orientation during automated placement.
Technical Context
This TVS operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds VRWM = 13 V. Its breakdown voltage (VBR) is specified at 14.4–15.9 V (min–max) with 1 mA test current, ensuring predictable turn-on behavior under transients.
Thermal design relies on low Rth(j-sp) = 18 K/W to solder point and junction temperature limit of 150 °C, enabling reliable operation in under-hood automotive environments where ambient temperatures reach 125 °C and board-level thermal dissipation is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W per IEC 61643-321 (10/1000 µs waveform) - sustains high-energy surges without failure |
| Reverse Standoff Voltage | VRWM = 13 V - blocks normal 12 V automotive system voltage while remaining inactive |
| Clamping Voltage | VCL = 21.5 V at IPPM = 18.6 A - limits downstream IC voltage to safe level during surge |
| Reverse Leakage | IRM = 0.001 µA at VRWM - negligible standby current, critical for battery-sensitive systems |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2) - protects against human-body and cable-discharge events |
| Package | SOD123W (CFP3): 2.6 × 1.7 × 1.0 mm - enables ultra-low-profile mounting on dense automotive PCBs |
| AEC-Q101 Qualified | Qualified for automotive discrete semiconductors - supports PPAP documentation and long-term reliability requirements |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package with 2 terminals, 1 mm height, and cathode-marked bar on top surface. Optimized for reflow soldering with recommended stencil thickness of 0.1 mm and defined land pattern per Figure 4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked side) | Cathode (K) | Connected to protected line (e.g., 12 V rail); absorbs positive transients when referenced to ground |
| 2 | Anode (A) | Connected to system ground; completes clamping path during overvoltage event |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q101 compliant - validated for temperature cycling, humidity, and mechanical stress per automotive standards |
| Low-profile footprint | 1.0 mm max height - fits beneath connectors and shields in compact ECU modules |
| High surge robustness | Withstands 50 A non-repetitive forward surge (IFSM) - handles load-dump and inductive kickback events |
| Polarity identification | Visible cathode bar marking - prevents misorientation during AOI inspection and automated assembly |
| Thermal performance | Rth(j-sp) = 18 K/W - enables efficient heat transfer to PCB copper, reducing junction temperature rise during repeated surges |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) CAN Bus Line |
|---|---|
Use Scenario: Protects 12 V input rail of engine control units against ISO 7637-2 pulse 5a (load dump) and pulse 1 (inductive switching). IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between battery feed and DC-DC converter input. Use Value: Clamps surge to ≤21.5 V, preventing damage to 24 V-tolerant regulators and preserving system uptime during cold-cranking recovery. | Use Scenario: Shields CAN_H/CAN_L signal lines in body control modules from ESD and coupled transients from nearby solenoid drivers. IC Role / Device Role / Timing Role: Low-capacitance TVS placed differential across bus pair, grounded via common-mode choke. Use Value: 0.001 µA leakage avoids bus bias shift; ±30 kV ESD rating meets OEM EMC test plans without degrading signal integrity. |
| Infotainment System USB Port | ADAS Camera Power Rail |
Use Scenario: Guards 5 V USB VBUS line in head-unit against hot-plug transients and external cable ESD. IC Role / Device Role / Timing Role: Standoff-rated TVS connected anode-to-ground, cathode-to-VBUS, upstream of USB controller. Use Value: 13 V VRWM ensures no conduction during nominal 5 V operation; 400 W rating absorbs multi-pulse ESD bursts per IEC 61000-4-2. | Use Scenario: Safeguards 12 V power input of radar/camera modules exposed to under-hood EMI and alternator ripple. IC Role / Device Role / Timing Role: Primary overvoltage clamp on camera module's main power entry, before LDO or buck regulator. Use Value: AEC-Q101 qualification ensures operation at 150 °C junction temperature; 1 mm height allows placement near connector edge without interference. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-Q | Same VRWM (13 V), but SMA package (2.8 × 4.5 × 2.3 mm) - 2.3× taller and 2.7× larger footprint | Lacks AEC-Q101 qualification; rated for industrial, not automotive use | Select only if board height >2.3 mm is acceptable and automotive qualification is not required |
| TPSMD13A | Higher VCL = 23.2 V at same IPPM; 1.5× higher Rth(j-a) = 100 K/W | Designed for telecom surge (IEC 61000-4-5), not optimized for automotive load dump | Prefer for telecom base stations; avoid in automotive due to higher clamping and lower thermal margin |
Compared with SMAJ13A-Q and TPSMD13A, PTVS13VS1UR-Q delivers superior automotive readiness via AEC-Q101 certification, minimal 1 mm height for tight packaging, and lower clamping voltage (21.5 V vs. ≥23.2 V), directly improving downstream IC survivability during load-dump events.

FAQ
What is the maximum clamping voltage for PTVS13VS1UR-Q at its rated peak pulse current?
The clamping voltage (VCL) is 21.5 V at peak pulse current (IPPM) of 18.6 A, measured per IEC 61643-321 10/1000 µs waveform. This value is guaranteed across temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
Does PTVS13VS1UR-Q support bidirectional transient suppression?
No - it is a unidirectional TVS diode, configured to clamp only positive transients on the cathode terminal relative to anode (ground). For bidirectional protection, two devices must be used in series opposition or a dedicated bidirectional variant like PTVS13VS1UR-Q-B should be selected.
How is polarity identified on the PTVS13VS1UR-Q package?
Polarity is marked by a visible bar on the top surface of the SOD123W package, aligned with Pin 1 (cathode). This bar matches the cathode symbol in the simplified outline (Figure 2) and must be oriented toward the protected line (e.g., 12 V rail) during placement.
Can PTVS13VS1UR-Q be used in non-automotive applications?
Yes - while AEC-Q101 qualified and optimized for automotive, its 400 W surge rating, low leakage, and SOD123W footprint make it suitable for industrial power supplies, medical equipment inputs, and any 12–13 V system requiring robust, space-efficient overvoltage protection with certified reliability.
