Product details
Overview
PTVS3V3S1UR,115 from Nexperia is a unidirectional 3.3 V transient voltage suppressor (TVS) diode in SOD123W (CFP3) package, rated for 350 W peak pulse power (10/1000 µs), with 5.2–6.0 V breakdown voltage, 8.0 V clamping voltage at 43.8 A, and <0.001 µA reverse leakage - designed for low-profile board-level ESD and surge protection in DC power rails.
For engineers reviewing the PTVS3V3S1UR,115 datasheet, PTVS3V3S1UR,115 pinout, PTVS3V3S1UR,115 application, or PTVS3V3S1UR,115 equivalent, this device serves as a compact, AEC-Q101-qualified overvoltage clamp for 3.3 V logic supply lines, USB power inputs, and automotive body-control module interfaces where height-constrained mounting and fast response to IEC 61000-4-2 ESD events are critical.
Technical Context
This unidirectional TVS operates as a silicon avalanche diode, triggering when reverse voltage exceeds its 3.3 V standoff threshold and clamping transients to ≤8.0 V at 43.8 A peak pulse current. Its junction-to-solder-point thermal resistance is 18 K/W, enabling effective heat dissipation during repetitive surges.
The device conforms to IEC 61643-321 (10/1000 µs waveform) and achieves 30 kV contact ESD immunity per IEC 61000-4-2. Its SOD123W footprint supports automated reflow assembly with 1.0 mm max height and 2.6 × 1.7 mm body dimensions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ3.3A | DO-214AC package (2.9 mm height), 400 W PPPM, 10.3 V VCL @ 38.8 A | Higher clamping voltage reduces protection margin for 3.3 V logic; unsuitable for height-critical layouts | Select only if board clearance >2.5 mm and clamping voltage margin ≥3.0 V is acceptable |
| TPSMA6L3.3 | SMA package (2.3 mm height), 600 W PPPM, 9.2 V VCL @ 43.5 A, AEC-Q101 qualified | Higher clamping voltage risks violating 3.3 V IC absolute maximum ratings; larger footprint requires layout revision | Prefer only when higher surge energy handling is required and mechanical constraints allow SMA footprint |
Compared with SMAJ3.3A and TPSMA6L3.3, PTVS3V3S1UR,115 delivers superior height efficiency (1.0 mm vs. ≥2.3 mm), tighter clamping (8.0 V vs. ≥9.2 V), and optimized leakage (<0.001 µA), making it the only choice for modern 3.3 V systems with strict mechanical and electrical margins.

FAQ
What is the maximum clamping voltage of PTVS3V3S1UR,115 under rated surge conditions?
The maximum clamping voltage is 8.0 V at 43.8 A peak pulse current (IPPM), measured per IEC 61643-321 10/1000 µs waveform. This value ensures protected 3.3 V ICs remain within their absolute maximum voltage rating during worst-case transients.
Is PTVS3V3S1UR,115 qualified for automotive use per AEC-Q101?
Yes - PTVS3V3S1UR,115 is explicitly listed in the revision history (v.4, Dec 2025) as one of 33 types changed to standard AEC-Q101 qualification, confirming full compliance with Stress Test Qualification for Discrete Semiconductors.
How does the SOD123W package affect thermal performance compared to SMA or DO-214AC?
The SOD123W's 18 K/W junction-to-solder-point thermal resistance (Rth(j-sp)) is significantly lower than SMA (≈35 K/W) or DO-214AC (≈45 K/W), enabling more efficient heat transfer to the PCB copper and supporting higher surge repetition rates without thermal runaway.
Can PTVS3V3S1UR,115 be used in bidirectional signal line protection?
No - it is strictly unidirectional. The pinout (cathode/anode) and IV characteristics confirm operation only in reverse-bias clamping mode. For bidirectional protection (e.g., data lines), a symmetric TVS array like PUSB3FR4 or dual-diode configuration is required.
