Product details
Overview
PTVS58VS1UTR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature transient overvoltage protection in power rails. It features VRWM = 58 V, VBR(min) = 64.4 V at 1 mA, VCL = 93.6 V at IPPM = 4.3 A (10/1000 µs), and operates up to Tj = 185 °C - deployed in industrial power supply input stages.
For engineers reviewing the PTVS58VS1UTR,115 datasheet, PTVS58VS1UTR,115 pinout, PTVS58VS1UTR,115 application, or PTVS58VS1UTR,115 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD tolerance, thermal resistance under PCB copper constraints, junction temperature derating at 150–185 °C, and ESD robustness (30 kV contact discharge).
Technical Context
This unidirectional TVS diode uses an avalanche breakdown structure optimized for fast response (<1 ns) to transients per IEC 61643-321 (10/1000 µs waveform). Its low IRM ≤ 0.001 µA at VRWM ensures minimal leakage in standby power paths.
Thermal design is enabled by Rth(j-sp) = 18 K/W to cathode solder point and stable SZ = 0.5 mV/K temperature coefficient - critical for predictable clamping across -55 °C to +185 °C ambient operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 58 V - maximum continuous reverse operating voltage before significant leakage; sets upper limit for protected rail voltage. |
| VBR (min) | 64.4 V at 1 mA - guaranteed avalanche initiation threshold; defines minimum overvoltage level triggering clamping. |
| VCL | 93.6 V at IPPM = 4.3 A (10/1000 µs) - peak clamped voltage seen by downstream circuitry during surge. |
| PPPM | 400 W - rated peak pulse power handling per IEC 61643-321; determines survivability of standardized lightning/surge events. |
| Tj max | 185 °C - maximum junction temperature rating; enables use in under-hood, motor drive, or high-ambient industrial environments. |
| IRM | ≤ 0.001 µA at VRWM - ultra-low reverse leakage preserves battery life and minimizes standby power loss. |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2); >8 kV HBM - provides system-level ESD immunity without external shielding. |
Pinout & Package
PTVS58VS1UTR,115 is housed in a SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, 1 mm profile height, with cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 58 V rail); clamping occurs when voltage exceeds VBR relative to anode. |
| 2 (A) | Anode | Typically tied to ground or low-impedance return path; completes avalanche conduction loop during transient. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Tj up to 185 °C enables placement near heat sources (e.g., MOSFETs, inductors) without derating. |
| Low-profile SMD package | 1 mm height allows integration into space-constrained power modules and dense PCB layouts. |
| Precision clamping stability | Temperature coefficient SZ = 0.5 mV/K ensures <±5 % VCL variation from -55 °C to +150 °C. |
| Ultra-low leakage | IRM ≤ 0.001 µA prevents measurable current draw in always-on 58 V monitoring circuits. |
| Robust surge handling | 400 W PPPM supports repeated 10/1000 µs surges per IEC 61000-4-5 Level 4 (4 kV line-to-earth). |
Applications
| Industrial Power Supply Input Protection | Motor Drive DC Bus Clamping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ58A | Lower PPPM = 400 W but higher VCL = 93.6 V; VRWM = 58 V; same SOD-123 package; Tj max = 150 °C. | Limited to ≤150 °C ambient; unsuitable for under-hood or enclosed high-temp enclosures. | Select only if thermal environment stays below 150 °C and footprint compatibility is mandatory. |
| SMCJ58A | Higher PPPM = 1500 W; larger DO-214AB package; VRWM = 58 V; VCL = 93.6 V; Tj max = 175 °C. | Requires 2× PCB area; better for high-energy surges but incompatible with ultra-thin designs. | Choose when surge energy exceeds 400 W capability and board space permits larger footprint. |
Compared with SMAJ58A, PTVS58VS1UTR,115 delivers 35 °C higher junction temperature margin and identical clamping performance in half the height; versus SMCJ58A, it trades 1100 W peak power for 60 % smaller footprint and 1 mm profile - ideal for thermally demanding, space-constrained 58 V systems.

FAQ
What is the maximum clamping voltage of PTVS58VS1UTR,115 under standard test conditions?
The clamping voltage VCL is 93.6 V at IPPM = 4.3 A using the 10/1000 µs current waveform per IEC 61643-321. This value is measured at Tj = 25 °C and represents the peak voltage imposed on the protected circuit during a defined surge event - critical for verifying margin against downstream device absolute maximum ratings.
Can PTVS58VS1UTR,115 be used in bidirectional protection configurations?
No - PTVS58VS1UTR,115 is a unidirectional TVS diode with cathode/anode polarity. It conducts only for positive transients on the cathode relative to anode. For bidirectional protection, two devices must be connected in series opposition, or a dedicated bidirectional part like PTVS58VS1UTR,115's counterpart in the PTVS58VS1UTR-B series must be selected.
How does the 185 °C junction temperature rating impact PCB layout?
The 185 °C Tj rating allows operation in high-thermal-load zones, but effective heat dissipation still requires adequate copper pour on the cathode pad (≥1 cm² tin-plated FR4 recommended per datasheet Table 6). Rth(j-sp) = 18 K/W assumes direct thermal coupling to the solder point - thermal vias under the cathode pad significantly improve reliability under sustained surge duty cycles.
Is the marking code 'D2' on PTVS58VS1UTR,115 verified per Nexperia documentation?
Yes - Table 4 of the datasheet explicitly lists PTVS58VS1UTR with marking code D2. This laser-marked identifier appears adjacent to the cathode bar on the SOD123W package body and is used for traceability and visual verification during assembly and inspection.
