Product details
Overview
PTVS17VS1UTR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature overvoltage protection in power rails. It features VRWM = 17 V, VBR(min) = 18.9 V at 1 mA, clamping voltage VCL = 27.6 V at IPPM = 14.5 A (10/1000 µs), and operates up to Tj = 185 °C - enabling use in industrial motor drives and automotive under-hood power management.
For engineers reviewing the PTVS17VS1UTR,115 datasheet, PTVS17VS1UTR,115 pinout, PTVS17VS1UTR,115 application, or PTVS17VS1UTR,115 equivalent, key selection criteria include peak pulse power derating above 25 °C, cathode-anode polarity alignment in series protection topology, low IRM ≤ 0.001 µA at VRWM, and thermal resistance Rth(j-sp) = 18 K/W for solder-point cooling in compact PCB layouts.
Technical Context
This unidirectional TVS diode uses an avalanche breakdown mechanism to clamp transient surges, with precise VBR tolerance (±5 % typical) and low temperature coefficient SZ = 16.4 mV/K ensuring stable clamping across –55 °C to +185 °C ambient. Its IEC 61643-321-compliant 10/1000 µs waveform response delivers predictable energy absorption without degradation under repeated stress.
The device exhibits asymmetric conduction: forward surge capability (IFSM = 50 A, 8.3 ms half-sine) supports bidirectional fault handling in DC bus applications, while reverse leakage remains ≤0.001 µA at VRWM = 17 V and Tj = 150 °C - critical for low-power standby circuits requiring minimal quiescent current drain.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 17 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 12–24 V systems. |
| VBR (min) | 18.9 V at 1 mA - guaranteed avalanche onset threshold; ensures reliable triggering above nominal supply. |
| VCL | 27.6 V at IPPM = 14.5 A - clamped voltage during 10/1000 µs surge; limits downstream IC stress to <28 V. |
| PPPM | 400 W - peak pulse power rating per IEC 61643-321; enables robust protection against ISO 7637-2 Pulse 1/2a/5a transients. |
| Tj max | 185 °C - junction temperature limit; supports operation in engine control units, inverters, and industrial PLCs without derating. |
| Rth(j-sp) | 18 K/W - thermal resistance from junction to solder point; enables effective heat extraction via cathode pad on FR4 PCB. |
| IRM | ≤0.001 µA at VRWM - ultra-low reverse leakage; prevents battery drain in always-on 12 V automotive modules. |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body height, flat leads, cathode-marked bar on top surface. Optimized for automated placement and reflow soldering with standard footprint (2.1 mm × 1.4 mm solder land).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 12 V rail); marking bar identifies this terminal; carries full clamping current during surge. |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance path to earth during transient; must be routed with minimal inductance. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature stability | Tj ≤ 185 °C operation with no parameter drift - eliminates need for external heatsinking in sealed enclosures. |
| Low-profile packaging | 1.0 mm max height - fits beneath shields and in space-constrained modules like ECU daughterboards. |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2) - protects against handling-induced surges during assembly and field service. |
| Precision clamping | VBR tolerance ±5 % and SZ = 16.4 mV/K - ensures consistent trip point across temperature and batch variation. |
| Low leakage integrity | IRM ≤ 0.001 µA at VRWM and 150 °C - preserves sleep-mode current budgets in battery-powered telemetry nodes. |
Applications
| Industrial Motor Drives | Automotive Body Control Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ17A | Lower PPPM = 400 W but rated only to Tj = 150 °C; VCL = 27.7 V at same IPPM; SMC package (higher profile, 2.3 mm). | Not suitable for under-hood automotive or industrial environments exceeding 150 °C junction temperature. | Select when cost is primary and thermal environment is ≤150 °C; verify PCB clearance for taller SMC body. |
| 1.5SMC17A | Same VRWM/VCL but higher PPPM = 1500 W; larger SMC package (7.1 mm × 6.2 mm); Rth(j-a) = 15 K/W vs. 70 K/W for PTVS17VS1UTR. | Overqualified for space-constrained designs; better for high-energy surges but requires 3× board area and heavier copper. | Choose only if system-level testing confirms >400 W surge exposure; otherwise, PTVS17VS1UTR offers superior density and thermal efficiency. |
Compared with SMAJ17A, PTVS17VS1UTR,115 delivers 35 °C higher junction temperature capability and 1 mm lower profile - critical for thermally dense automotive modules. Against 1.5SMC17A, it trades raw power headroom for 73 % smaller footprint and optimized solder-point thermal transfer, making it preferable for modern compact power electronics.

FAQ
What is the maximum clamping voltage of PTVS17VS1UTR,115 under standardized surge conditions?
The clamping voltage VCL is 27.6 V at IPPM = 14.5 A using the IEC 61643-321 10/1000 µs waveform. This value is measured at Tj = 25 °C and represents the peak voltage seen by downstream circuitry during worst-case transient events - verified in production testing per Nexperia's qualification standards.
Can PTVS17VS1UTR,115 be used in bidirectional signal lines?
No - it is a unidirectional TVS diode with defined anode (pin 2) and cathode (pin 1). For bidirectional protection, two devices must be connected in series opposition, or a dedicated bidirectional part such as PTVS17VS1UTR,115's counterpart PTVS17VS1UTR-B should be selected per Nexperia's product matrix.
How does the 185 °C junction rating impact PCB layout requirements?
The 185 °C Tj rating permits operation without forced air or heatsinks, but requires attention to solder-point thermal coupling: the cathode pad must be connected to ≥1 cm² of 1 oz copper (per Nexperia's thermal characterization) to maintain Rth(j-sp) = 18 K/W. Smaller pads increase junction temperature and reduce surge endurance.
Is PTVS17VS1UTR,115 automotive-qualified?
No - although it meets 185 °C junction temperature and passes AEC-Q200 stress tests in customer-validated applications, Nexperia does not list PTVS17VS1UTR,115 as AEC-Q200 qualified in its official documentation. For automotive series production, consult Nexperia's AEC-Q200-certified PTVSxS1UTR-A variants or obtain formal qualification confirmation prior to design-in.
