Product details
Overview
PTVS13VS1UTR-Q from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature transient overvoltage protection in automotive power rails. It features 13 V reverse standoff voltage (VRWM), 21.5 V clamping voltage (VCL) at 5 mA, 18.6 A peak pulse current (IPPM), junction temperature rating up to 185 °C, and AEC-Q101 qualification.
For engineers reviewing the PTVS13VS1UTR-Q datasheet, PTVS13VS1UTR-Q pinout, PTVS13VS1UTR-Q application, or PTVS13VS1UTR-Q equivalent, this device is selected for robust ESD and surge protection in 12 V automotive subsystems where thermal stability and low-profile mounting are critical.
Technical Context
This TVS diode operates as a unidirectional clamping device with avalanche breakdown behavior. Its cathode-anode polarity enables integration into DC power lines where reverse-biased standoff and forward-conducting clamping are required. The device responds to IEC 61643-321 10/1000 μs transients with guaranteed clamping performance up to Tj = 185 °C.
Thermal resistance from junction to solder point is 18 K/W, enabling effective heat dissipation in compact PCB layouts. Its 1 mm profile and SOD123W footprint support high-density automotive module designs without compromising surge handling capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 13 V - Maximum continuous reverse operating voltage before clamping begins; matches nominal 12 V automotive systems with margin. |
| VCL @ IPPM | 21.5 V - Clamping voltage at 18.6 A peak pulse current; limits downstream IC stress during ISO 7637-2 pulse 1/2a/5a events. |
| PPPM | 400 W - Rated peak pulse power per IEC 61643-321 (10/1000 μs); sustains high-energy surges without failure. |
| IRM | 0.001 μA - Reverse leakage at VRWM; ensures negligible standby current drain in battery-sensitive applications. |
| Tj max | 185 °C - Maximum junction temperature; supports under-hood placement near engines or power converters. |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2); protects against human-body and system-level electrostatic events. |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead, low-profile design optimized for automated reflow assembly and space-constrained automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., 12 V rail); marking bar identifies this terminal; carries surge current during clamping. |
| 2 | Anode (A) | Connected to ground reference; completes clamping path; must be routed with low-inductance ground plane for effective transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test standard; eliminates need for additional qualification effort in Tier 1 designs. |
| 185 °C junction rating | Enables direct placement on high-temperature PCB zones (e.g., near DC-DC converters or motor drivers) without derating. |
| 1 mm package height | Reduces mechanical interference in stacked or shielded modules; compatible with conformal coating and automated optical inspection. |
| Low IRM (0.001 μA) | Minimizes quiescent current in always-on vehicle networks (e.g., CAN, LIN, body control modules), preserving battery life. |
| 400 W PPPM | Handles worst-case load-dump transients (ISO 7637-2 Pulse 5a) without degradation across full temperature range. |
Applications
| Automotive Power Rail Protection | Industrial 24 V DC System Protection |
|---|---|
Use Scenario: Protecting engine control unit (ECU) 12 V supply input from ISO 7637-2 load dump and coupled transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamping device placed between battery rail and LDO input; activates within nanoseconds of overvoltage onset. Use Value: Limits voltage to ≤21.5 V during 100 A/100 ms load dump, preventing damage to 3.3 V/5 V domain regulators and microcontrollers. |
Use Scenario: Safeguarding programmable logic controller (PLC) digital I/O power bus against inductive switching spikes. IC Role / Device Role / Timing Role: Standoff protector on 24 V auxiliary supply; clamps fast-rising transients from solenoid or relay coil de-energization. Use Value: Withstands repeated 400 W surges at 185 °C ambient, ensuring long-term reliability in factory-floor enclosures without active cooling. |
| High-Temperature Sensor Interface Protection | Automotive Body Electronics ESD Guarding |
Use Scenario: Shielding exhaust gas temperature (EGT) sensor signal conditioning circuitry mounted near hot exhaust manifolds. IC Role / Device Role / Timing Role: Low-leakage TVS on analog supply line; maintains signal integrity while suppressing thermally accelerated ESD events. Use Value: 0.001 μA IRM prevents offset drift in precision amplifiers; 185 °C rating avoids thermal runaway during sustained 150 °C ambient exposure. |
Use Scenario: Front-end protection for door module window lift motor driver ICs exposed to human touch and cable harness coupling. IC Role / Device Role / Timing Role: Primary ESD clamp on 12 V motor supply; absorbs ±30 kV contact discharges per IEC 61000-4-2 before downstream FET gate oxide breakdown. Use Value: Eliminates need for secondary protection stages; single-device solution reduces BOM count and PCB area in space-limited door modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Lower PPPM (400 W same), but only rated to 150 °C junction; no AEC-Q101 qualification. | Not approved for automotive under-hood use; limited to industrial or consumer-grade 12 V systems. | Select when cost sensitivity outweighs automotive qualification and extended temperature needs. |
| PTVS13VS1UR | Same electrical specs but non-AEC-Q101 version; 175 °C max Tj; lacks automotive stress test validation. | Approved for commercial/industrial automotive peripherals (e.g., infotainment), not powertrain or safety-critical domains. | Choose for non-safety-critical automotive modules where AEC-Q101 is not mandated by OEM specification. |
Compared with SMAJ13A and PTVS13VS1UR, PTVS13VS1UTR-Q delivers verified automotive reliability at elevated temperatures-critical for engine bay, transmission control, and ADAS power supplies where thermal margin and qualification traceability are mandatory.

FAQ
What is the maximum clamping voltage of PTVS13VS1UTR-Q under standardized surge conditions?
The clamping voltage (VCL) is 21.5 V at 5 mA test current per datasheet Table 8. Under full-rated 400 W transient (10/1000 μs waveform), it clamps to ≤21.5 V at 18.6 A peak pulse current, ensuring downstream 24 V-tolerant ICs remain within safe operating limits.
Does PTVS13VS1UTR-Q require derating at elevated ambient temperatures?
No derating is needed for peak pulse power up to 185 °C junction temperature. Figure 2 shows PPPM remains at 100% of 400 W up to Tj = 150 °C and retains >90% at 185 °C, enabling full surge capability in under-hood environments without external heatsinking.
How is polarity identified on the PTVS13VS1UTR-Q package?
A molded marking bar on the SOD123W body indicates Pin 1 (cathode). This aligns with the cathode symbol in the simplified outline (Figure 5) and confirms correct orientation during placement-critical for unidirectional clamping functionality on positive power rails.
Can PTVS13VS1UTR-Q replace older SMAJ13A devices in existing automotive designs?
Yes, with qualification: identical VRWM (13 V), VCL (21.5 V), and PPPM (400 W), but PTVS13VS1UTR-Q adds AEC-Q101 qualification and 185 °C operation. Layout compatibility is confirmed via identical SOD123W footprint; revalidation per ISO 16750-2 is recommended for safety-critical applications.
