Product details
Overview
PTVS18VP1UP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-energy surge protection on DC power rails and signal lines. It features 18 V reverse standoff voltage (VRWM), 21 V typical breakdown voltage (VBR), 29.2 V clamping voltage (VCL) at 20.5 A peak pulse current (IPPM), and <0.001 µA reverse leakage at VRWM - deployed in industrial power management and automotive subsystems requiring IEC 61643-321 compliance.
For engineers reviewing the PTVS18VP1UP,115 datasheet, PTVS18VP1UP,115 pinout, PTVS18VP1UP,115 application, or PTVS18VP1UP,115 equivalent, this device serves as a surface-mount overvoltage clamp with precise 18 V threshold, low-profile 1 mm height, and AEC-Q101 qualification status confirmed in revision v.3 (2025).
Technical Context
This unidirectional TVS operates as a silicon avalanche diode that remains non-conductive below VRWM = 18 V and clamps transient energy above VBR ≈ 21 V using a 10/1000 µs waveform per IEC 61643-321. Its junction-to-solder-point thermal resistance is 12 K/W, enabling effective heat dissipation during repetitive surges.
The device exhibits 0.001 µA IRM at VRWM, ensuring minimal standby power loss, and achieves 600 W peak pulse power (PPPM) at Tj = 25 °C - derating to ~40% at 125 °C per Fig. 2. Its SOD128 footprint supports automated reflow assembly with defined solder land dimensions (3.4 mm × 2.1 mm per cathode/anode pad).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W - sustains single 10/1000 µs transients up to 600 W without failure under IEC 61643-321 conditions |
| Reverse Standoff Voltage (VRWM) | 18 V - maximum continuous DC voltage before significant leakage; sets operating margin for 18 V rail protection |
| Breakdown Voltage (VBR) | 20.0–22.1 V (min–max at IR = 1 mA) - precise avalanche onset ensures predictable clamping initiation |
| Clamping Voltage (VCL) | 29.2 V at IPPM = 20.5 A - limits downstream voltage stress during surge, protecting 3.3–24 V logic and analog circuitry |
| Reverse Leakage (IRM) | 0.001 µA at VRWM - negligible standby current avoids battery drain or sensor offset in always-on systems |
| Package | SOD128 (CFP5) - 3.8 mm × 2.6 mm × 1.0 mm surface-mount outline with 4 mm lead pitch and cathode-marked bar |
| Junction Temp Limit (Tj) | 150 °C - enables operation in under-hood or industrial enclosures without thermal shutdown |
Pinout & Package
SOD128 (CFP5) plastic surface-mounted package: 2-terminal, flat-lead, 1 mm profile; marking bar denotes cathode (Pin 1). Optimized for high-density PCB layouts and automated placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., +18 V rail); carries surge current into ground path during clamping |
| 2 (A) | Anode | Connected to system ground; completes conduction path when transient exceeds VBR; requires low-inductance grounding |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive subsystems including body control modules and infotainment power supplies per revision v.3 (2025) |
| Low-profile SOD128 package | 1.0 mm height enables use in space-constrained modules such as ADAS camera ECUs and motor drivers |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2) and >4 kV HBM rating protect against handling and system-level ESD events |
| Thermal performance | 12 K/W junction-to-solder-point resistance allows direct thermal coupling to copper pour for sustained surge handling |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |
|---|---|
|
Use Scenario: 24 V DC input stage of programmable logic controller (PLC) power supply exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between input rail and ground to limit voltage excursion during 10/1000 µs surges. Use Value: Clamps to ≤29.2 V at 20.5 A, preventing damage to upstream rectifiers and downstream DC-DC controllers rated for 36 V max. |
Use Scenario: 12 V auxiliary power rail in BCM supplying window lift motors and door lock actuators. IC Role / Device Role / Timing Role: Primary overvoltage protector against ISO 7637-2 Pulse 5a (load dump) events up to 60 V peak. Use Value: AEC-Q101 qualification and 600 W PPPM ensure reliability across temperature (-40 °C to 125 °C ambient) and lifetime requirements. |
| Industrial Sensor Interface Protection | Smart Lighting Driver Input Stage |
|
Use Scenario: 18 V bias rail for 4–20 mA current-loop sensors in factory automation cabinets subject to cable-induced surges. IC Role / Device Role / Timing Role: Fast-response avalanche diode shunting transients before they reach precision op-amps and ADC front-ends. Use Value: 0.001 µA IRM preserves sensor accuracy; 29.2 V VCL prevents saturation of 3.3 V microcontroller I/O pins via level-shifting circuitry. |
Use Scenario: Input stage of constant-current LED driver for street lighting, connected to outdoor AC/DC converter output. IC Role / Device Role / Timing Role: Secondary surge limiter after MOV, absorbing residual energy from lightning-induced surges on 24–48 V DC bus. Use Value: SOD128 footprint allows parallel placement with input capacitors; 1 mm height avoids interference with heatsink mounting. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ18A | DO-214AC package (2.8 mm height), 400 W PPPM, 20.0 V VRWM, 29.2 V VCL at 13.7 A | Lower power rating and taller profile limit use in ultra-thin automotive modules | Select when cost sensitivity outweighs space constraints and 600 W headroom is unnecessary |
| SMCJ18A | DO-214AB package (2.6 mm height), 1500 W PPPM, 18 V VRWM, 29.2 V VCL at 51.3 A | Larger footprint and higher clamping energy require revised PCB layout and thermal design | Choose for heavy-duty industrial equipment where 1500 W surge immunity justifies added size and cost |
Compared with SMAJ18A and SMCJ18A, PTVS18VP1UP,115 delivers optimal balance of 600 W surge capacity, 1 mm profile, and AEC-Q101 validation - making it preferred for space-limited automotive and industrial designs requiring verified reliability without over-engineering.

FAQ
Is PTVS18VP1UP,115 suitable for automotive applications?
Yes - PTVS18VP1UP,115 is explicitly qualified to AEC-Q101 (per revision v.3, December 2025) and listed among the 25 products granted standard automotive qualification in the latest datasheet revision. It is validated for use in body control modules, infotainment power supplies, and other non-safety-critical automotive subsystems.
What is the maximum clamping voltage under surge conditions?
The clamping voltage (VCL) is 29.2 V at 20.5 A peak pulse current (IPPM), measured per IEC 61643-321 10/1000 µs waveform. This value is guaranteed across the full operating temperature range (−55 °C to 150 °C junction), with no derating required for standard surge durations.
How does the SOD128 package affect thermal performance?
The SOD128 package provides a junction-to-solder-point thermal resistance (Rth(j-sp)) of 12 K/W when mounted per recommended footprint (Fig. 7), enabling efficient heat transfer to PCB copper. This allows sustained surge handling without thermal runaway, unlike larger packages with higher Rth(j-a) values in free air.
Can PTVS18VP1UP,115 replace older PTVS18V1UP variants?
No - PTVS18VP1UP,115 supersedes earlier PTVS18V1UP versions with updated qualification status and tighter parameter tolerances. The "P1UP" suffix denotes the current qualified series; legacy "1UP" parts lack the 2025 AEC-Q101 confirmation and exhibit wider VBR spread (±10% vs. ±5% in new series), requiring redesign verification.
