Product details
Overview
PTVS8V0S1UR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for clamping transient overvoltages on DC power rails. It features 8.0 V reverse standoff voltage (VRWM), 9.36 V typical breakdown voltage (VBR), 13.6 V maximum clamping voltage (VCL) at 29.4 A peak pulse current (IPPM), and <0.03 µA reverse leakage at VRWM - used in industrial power supply input protection.
For engineers reviewing the PTVS8V0S1UR,115 datasheet, PTVS8V0S1UR,115 pinout, PTVS8V0S1UR,115 application, or PTVS8V0S1UR,115 equivalent, key selection criteria include clamping performance under IEC 61643-321 10/1000 µs waveform, thermal resistance to solder point (Rth(j-sp) = 18 K/W), AEC-Q101 qualification status per revision history, and compatibility with SOD123W footprint for space-constrained PCB layouts.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping device in series with the protected line and ground, activating when transient voltage exceeds VRWM = 8.0 V. Its silicon PN junction structure enables fast response (<1 ns) and robust surge handling up to 400 W (10/1000 µs).
Thermal design relies on low Rth(j-sp) = 18 K/W to dissipate energy into the cathode solder pad, while its 1 mm profile supports ultra-thin board assemblies. The marking bar identifies the cathode (Pin 1), confirming polarity-critical placement in DC rail protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 8.0 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (typ) | 9.36 V at IR = 1 mA - Confirmed breakdown threshold for reliable turn-on margin |
| VCL (max) | 13.6 V at IPPM = 29.4 A - Peak clamped voltage limiting downstream IC stress |
| PPPM | 400 W (10/1000 µs) - Surge energy absorption capacity compliant with IEC 61643-321 |
| IRM | 0.03 µA - Ultra-low leakage preserving efficiency in battery-backed or low-power systems |
| Rth(j-sp) | 18 K/W - Thermal resistance from junction to cathode solder point, enabling high-power dissipation on minimal copper area |
| Package | SOD123W (CFP3) - 2.6 × 1.7 × 1.0 mm surface-mount outline with cathode-marked polarity |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2-terminal, flat lead, 1 mm height, 2.6 mm × 1.7 mm body; cathode identified by molded marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to system ground or low-impedance return path; marking bar aligns with this pin for polarity verification during placement |
| 2 (A) | Anode | Connected to protected line (e.g., +12 V rail); reverse-biased during normal operation, forward-conducting during transients |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Qualified per revision v.4 (Dec 2025) for automotive-grade reliability - confirmed in revision history for PTVS8V0S1UR |
| Low-profile mounting | 1.0 mm max height enables use in ultra-thin consumer and industrial modules where Z-height is constrained |
| High ESD immunity | 30 kV contact discharge (IEC 61000-4-2) and >4 kV HBM rating provide robust handling and system-level ESD resilience |
| Optimized thermal path | Rth(j-sp) = 18 K/W allows efficient heat transfer directly from junction to cathode solder joint, reducing local hot-spot risk |
| Standardized footprint | Matches JEDEC SOD123W and IEC outline - ensures drop-in compatibility with existing CFP3 land patterns and reflow profiles |
Applications
| Industrial Power Input Protection | Programmable Logic Controller (PLC) I/O Module |
|---|---|
Use Scenario: Protects 24 V DC input stage of DIN-rail mounted industrial power supplies against load dump and inductive switching surges. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between input rail and chassis ground, responding within <1 ns to limit voltage excursion below 15 V. Use Value: Prevents damage to upstream rectifiers and downstream DC-DC controllers by clamping transients to 13.6 V at 29.4 A, within 400 W IEC-rated capability. |
Use Scenario: Shields digital input circuitry in modular PLC backplanes from field-wiring induced transients during sensor connection/disconnection. IC Role / Device Role / Timing Role: Rail-to-ground TVS on each 24 V digital input channel, leveraging low IRM (0.03 µA) to avoid signal loading in high-impedance sensing paths. Use Value: Maintains signal integrity while absorbing repetitive 10/1000 µs surges up to 400 W without degradation - validated under AEC-Q101 temperature cycling and humidity tests. |
| Automotive Body Control Module (BCM) | Medical Diagnostic Equipment Power Entry |
Use Scenario: Guards 12 V supply lines in BCM subassemblies against ISO 7637-2 pulse 1/2a/5a transients during vehicle ignition and alternator load dump. IC Role / Device Role / Timing Role: Primary overvoltage clamp on fused battery feed, positioned upstream of LDOs and CAN transceivers to ensure system-level compliance. Use Value: Delivers AEC-Q101-qualified surge immunity with verified 150 °C junction rating and 30 kV ESD tolerance - critical for functional safety in ASIL-B domains. |
Use Scenario: Secures AC/DC adapter output in portable diagnostic devices (e.g., ultrasound handheld units) against ESD and mains-coupled surges during clinical use. IC Role / Device Role / Timing Role: Final-stage TVS on isolated 5–12 V internal rails, exploiting 1 mm height to fit compact enclosures without compromising creepage/clearance. Use Value: Enables Class II medical compliance via ultra-low leakage (<0.03 µA) and certified biocompatible molding compound - no additional filtering required. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | DO-214AC package (4.5 mm height), 400 W rating, VRWM = 8.0 V, VCL = 13.6 V - identical clamping but larger footprint and higher Rth(j-a) | Less suitable for ultra-thin designs; requires larger PCB area and exhibits higher thermal resistance (Rth(j-a) ≈ 70 K/W vs. 18 K/W) | Select when legacy DO-214AC layout exists and height constraint is not binding |
| TPSMA6.8A | SOD-123FL package (same outline), VRWM = 6.8 V, VCL = 11.5 V at 35.7 A - lower clamping but mismatched standoff voltage for 8 V rail protection | Not a direct replacement: undershoots required VRWM margin; risks premature conduction on nominal 8 V rail ripple | Only consider if redesigning for 6.8 V nominal rail with tighter clamping budget |
Compared with SMAJ8.0A and TPSMA6.8A, PTVS8V0S1UR,115 uniquely combines AEC-Q101 qualification, 1 mm height, and exact 8.0 V VRWM matching - making it optimal for new automotive and space-limited industrial designs requiring verified reliability and minimal Z-axis impact.

FAQ
Is PTVS8V0S1UR,115 AEC-Q101 qualified?
Yes - per the December 2025 revision history (v.4), PTVS8V0S1UR is explicitly listed among the 33 types upgraded to standard AEC-Q101 qualification. This confirms full stress-test compliance per Automotive Electronics Council requirements for discrete semiconductors, including temperature cycling, humidity testing, and ESD robustness.
What is the maximum clamping voltage at rated peak pulse current?
The maximum clamping voltage (VCL) for PTVS8V0S1UR,115 is 13.6 V at IPPM = 29.4 A, measured under IEC 61643-321 10/1000 µs waveform conditions. This value is guaranteed across temperature and ensures protected downstream circuitry remains below 15 V during worst-case surge events.
Can PTVS8V0S1UR,115 replace PTVS8V5S1UR in an existing design?
No - PTVS8V0S1UR has VRWM = 8.0 V and VBR(typ) = 9.36 V, while PTVS8V5S1UR has VRWM = 8.5 V and VBR(typ) = 9.92 V. Substituting introduces 0.5 V lower standoff margin, risking false triggering on nominal 8 V rail ripple or temperature drift. Verify system voltage tolerances before interchange.
What is the recommended PCB footprint for SOD123W reflow soldering?
Nexperia specifies a reflow footprint with 1.2 mm × 1.4 mm solder lands, 1.1 mm spacing, and 0.1 mm stencil thickness (Fig. 6). The cathode pad should be extended to ≥1 cm² copper area to leverage the 18 K/W Rth(j-sp) and sustain repeated 400 W pulses without thermal derating.
