Product details
Overview
PTVS15VS1UR-Q from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for automotive-grade overvoltage protection on DC power rails. It features VRWM = 15 V, VBR(min) = 16.7 V, VCL(max) = 24.4 V at IPPM = 16.4 A (10/1000 µs), and meets AEC-Q101 qualification for under-hood electronics.
For engineers reviewing the PTVS15VS1UR-Q datasheet, PTVS15VS1UR-Q pinout, PTVS15VS1UR-Q application, or PTVS15VS1UR-Q equivalent, this device is selected for robust clamping performance in 12 V automotive subsystems, low-profile PCB layouts, and high-reliability transient suppression where IRM ≤ 0.1 µA and Rth(j-a) ≤ 220 K/W are critical.
Technical Context
This unidirectional TVS operates as a clamping diode in reverse-bias configuration, triggering at breakdown voltage (VBR = 16.7–18.5 V) to divert surge current away from sensitive circuitry. Its IEC 61643-321-compliant 10/1000 µs waveform rating ensures validated performance against automotive load-dump and ISO 7637-2 transients.
The SOD123W package enables surface-mount integration with 1 mm height and thermal resistance to ambient of 220 K/W on standard FR4, supporting compact power rail protection without heatsinking. Cathode-anode polarity is marked by a bar on the package body per IEC JEDEC outline.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 15 V - Maximum continuous reverse operating voltage before leakage exceeds 0.1 µA; sets upper limit for protected line nominal voltage. |
| VBR (min) | 16.7 V - Minimum breakdown voltage at 1 mA test current; defines earliest clamping onset under surge conditions. |
| VCL (max) | 24.4 V - Maximum clamped voltage at IPPM = 16.4 A (10/1000 µs); determines peak stress imposed on downstream ICs. |
| PPPM | 400 W - Peak pulse power handling capability per IEC 61643-321; supports single-event surges up to 16.4 A × 24.4 V. |
| IRM | 0.1 µA - Reverse leakage current at VRWM; ensures minimal quiescent power loss in always-on 12 V systems. |
| AEC-Q101 | Qualified - Validated for automotive discrete semiconductor stress testing including temperature cycling, HBM ESD (8 kV), and humidity bias. |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2.6 mm × 1.7 mm × 1.0 mm body, flat leads, cathode marked by bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 12 V rail); marking bar identifies this terminal; carries surge current during clamping. |
| 2 (A) | Anode | Connected to ground reference; completes conduction path during transient events; must be low-inductance ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power | Enables protection against severe ISO 7637-2 Pulse 5a (load dump) transients without derating in SOD123W footprint. |
| 1 mm package height | Allows placement beneath connectors or in tight engine-control-unit (ECU) layouts where Z-axis space is constrained. |
| 0.1 µA max IRM at VRWM | Minimizes standby current draw in always-powered automotive modules such as CAN transceivers or sensor interfaces. |
| AEC-Q101 qualification | Confirms reliability across -55 °C to +150 °C junction temperature range and validates suitability for front-end power stages in ADAS ECUs. |
Applications
| Automotive Power Rail Protection | Industrial 24 V Control System |
|---|---|
Use Scenario: Protecting microcontroller power input in body control module exposed to ISO 7637-2 load dump pulses. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between 12 V supply and local LDO input. Use Value: Limits transient voltage to ≤24.4 V, preventing latch-up or damage to 3.3 V/5 V logic supplies downstream. |
Use Scenario: Safeguarding PLC I/O driver stage against inductive kickback from solenoid switching. IC Role / Device Role / Timing Role: Fast-response overvoltage clamp on 24 V DC output rail. Use Value: Clamps 10/1000 µs surges within 1 ns, maintaining system uptime without sacrificial fuse replacement. |
| Automotive Sensor Interface | Telematics Module Power Input |
Use Scenario: Shielding LIN bus transceiver VCC pin from battery line transients during ignition cycling. IC Role / Device Role / Timing Role: Low-leakage TVS directly at transceiver power pin, adjacent to decoupling capacitor. Use Value: IRM ≤ 0.1 µA avoids signal integrity degradation while providing 16.4 A surge current diversion. |
Use Scenario: Securing LTE modem power entry in vehicle infotainment head unit subject to jump-start surges. IC Role / Device Role / Timing Role: Primary overvoltage guard before DC-DC converter input stage. Use Value: Withstands 30 kV contact ESD per IEC 61000-4-2, eliminating need for secondary ESD protection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-Q | Lower PPPM (400 W same), but higher VCL = 24.9 V at same IPPM; SMA package (2.5 mm height). | Less suitable for ultra-low-profile designs; slightly higher clamping increases risk to 3.3 V logic. | Select only if board layout permits taller profile and existing SMA footprint reuse is prioritized. |
| TPSMF15A | Same VRWM/VCL specs, but lower IRM (0.001 µA) and higher thermal resistance (Rth(j-a) = 250 K/W). | Reduced leakage benefits battery-critical modules, but requires larger copper pour for thermal management. | Prefer when ultra-low standby current outweighs PCB area constraints and thermal margin is verified. |
Compared with SMAJ15A-Q and TPSMF15A, PTVS15VS1UR-Q delivers identical 15 V standoff with superior height constraint compliance (1 mm), tighter VCL tolerance (24.4 V), and optimized thermal performance on standard FR4-making it the preferred choice for space-constrained automotive ECUs.

FAQ
What is the maximum clamping voltage for PTVS15VS1UR-Q under a 10/1000 µs surge?
The maximum clamping voltage (VCL) is 24.4 V at rated peak pulse current (IPPM) of 16.4 A, measured per IEC 61643-321. This value is guaranteed across the full operating temperature range (-55 °C to +150 °C) and defines the absolute worst-case voltage seen by downstream components during surge events.
Does PTVS15VS1UR-Q support bidirectional transient suppression?
No. PTVS15VS1UR-Q is a unidirectional TVS diode, configured for reverse-bias operation only. It protects against positive transients on the cathode side relative to anode (ground). For bidirectional protection-such as AC lines or data buses-separate symmetrical TVS devices like PTVS15VS1UR-S (bidirectional variant) must be used.
How is polarity identified on the SOD123W package?
Polarity is indicated by a marking bar printed on the top surface of the SOD123W package, aligned with Pin 1 (cathode). The cathode (K) connects to the protected line, while Pin 2 (anode) connects to ground. This matches the simplified outline in Nexperia's datasheet Figure 2 and package drawing Figure 3.
Can PTVS15VS1UR-Q replace PTVS15VS1UR without design changes?
Yes-PTVS15VS1UR-Q is the automotive-qualified version of PTVS15VS1UR, sharing identical electrical characteristics, pinout, and SOD123W package. The "-Q" suffix denotes AEC-Q101 qualification, including enhanced testing for temperature cycling, ESD, and humidity bias; no layout or schematic modifications are required for drop-in replacement in automotive designs.
