Product details
Overview
PTVS58VP1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at VRWM = 58 V, VBR(min) = 64.4 V, and clamping voltage VCL = 93.6 V at IPPM = 9.36 A under 10/1000 µs waveform. It delivers 30 kV IEC 61000-4-2 ESD immunity and operates up to 150 °C junction temperature.
For engineers reviewing the PTVS58VP1UP-QX datasheet, PTVS58VP1UP-QX pinout, PTVS58VP1UP-QX application, or PTVS58VP1UP-QX equivalent, this device is selected for robust transient suppression in 12 V/24 V automotive power rails, battery management systems, and industrial DC power inputs where low leakage (IRM ≤ 0.001 µA), tight clamping ratio (VCL/VBR ≈ 1.46), and AEC-Q101 qualification are critical.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping protector: under normal bias (VRWM = 58 V), it draws ≤0.001 µA reverse leakage; during transients exceeding VBR (min 64.4 V), it avalanches to clamp voltage VCL = 93.6 V at 9.36 A peak pulse current (IPPM), limiting energy dissipation per IEC 61643-321 10/1000 µs waveform.
Its thermal design supports high-reliability operation with Rth(j-a) = 200 K/W on FR4 PCB and Rth(j-sp) = 12 K/W to cathode solder point, enabling sustained surge handling in constrained automotive ECUs and power modules. The SOD128 package's 1 mm height and 3.8 × 2.6 mm footprint optimize board space without compromising thermal or electrical performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W - Sustains 10/1000 µs surges up to 600 W without failure per IEC 61643-321. |
| Reverse Standoff Voltage (VRWM) | 58 V - Maximum continuous DC operating voltage before significant leakage begins. |
| Breakdown Voltage (VBR) | 64.4 V (min) - Avalanche onset voltage at 1 mA test current; ensures reliable triggering above system nominal voltage. |
| Clamping Voltage (VCL) | 93.6 V at IPPM = 9.36 A - Maximum voltage seen by protected circuit during rated surge event. |
| Reverse Leakage (IRM) | ≤0.001 µA at VRWM - Negligible standby current, critical for low-power always-on automotive modules. |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - Full-system ESD resilience without external shielding layers. |
| Junction Temperature (Tj) | −55 °C to +150 °C - Supports under-hood deployment in engine control units and ADAS power supplies. |
Pinout & Package
PTVS58VP1UP-QX uses the SOD128 (CFP5) surface-mount plastic package: 2-terminal, 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm pitch, 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., 12 V rail); avalanche conduction occurs from anode to cathode during overvoltage. |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance shunt path during transient events. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress-test standard, enabling deployment in safety-critical power domains without requalification. |
| Low-profile SOD128 package | 1.0 mm max height enables integration into space-constrained modules like battery disconnect units and radar power stages. |
| High ESD immunity | ±30 kV contact discharge withstand eliminates need for supplemental ESD protection in CAN/LIN bus power interfaces. |
| Tight clamping ratio | VCL/VBR ≈ 1.46 ensures minimal overvoltage margin beyond breakdown, protecting downstream 100 V-rated MOSFETs and controllers. |
| Ultra-low leakage | ≤0.001 µA at 58 V allows use in always-on vehicle networks (e.g., LIN sleep mode) without battery drain concerns. |
Applications

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-Q | Lower PPPM (400 W), higher VCL (107 V at 5.6 A), same SOD-123 package but non-AEC-Q101. | Limited to non-automotive industrial use due to lack of automotive qualification and reduced surge margin. | Select when cost sensitivity outweighs AEC-Q101 compliance and 600 W surge headroom is not required. |
| SMCJ58A-Q | Same 600 W rating and AEC-Q101, but larger DO-214AB (SMC) package (7.1 × 6.2 × 2.6 mm) and higher VCL (96.8 V at 9.68 A). | Acceptable for under-dash modules with less space constraint; unsuitable for ultra-thin ECUs or radar sensors. | Choose when board real estate permits larger footprint and slightly higher clamping voltage is acceptable. |
Compared with SMAJ58A-Q and SMCJ58A-Q, PTVS58VP1UP-QX uniquely combines AEC-Q101 qualification, 600 W capability, SOD128 compactness (3.8 × 2.6 × 1.0 mm), and lowest VCL (93.6 V) in its class-making it optimal for next-gen automotive electronics where size, reliability, and precise clamping are jointly prioritized.

FAQ
What is the maximum clamping voltage of PTVS58VP1UP-QX under rated surge conditions?
The maximum clamping voltage (VCL) is 93.6 V at a peak pulse current (IPPM) of 9.36 A, measured per IEC 61643-321 10/1000 µs waveform. This value is guaranteed across the full operating temperature range (−55 °C to +150 °C) and defines the upper voltage limit imposed on protected circuitry during worst-case transients.
Is PTVS58VP1UP-QX suitable for bidirectional signal line protection?
No. PTVS58VP1UP-QX is a unidirectional TVS diode, optimized for DC power rail protection where polarity is fixed (e.g., 12 V to ground). It conducts only in reverse breakdown and offers no protection against positive-going transients on grounded lines. For bidirectional signal lines, a symmetric TVS like PTVS58VS1UP-Q must be used instead.
How does the SOD128 package affect thermal performance compared to larger packages?
The SOD128 package achieves Rth(j-sp) = 12 K/W to the cathode solder point-superior to many larger packages-due to its low-profile copper clip construction and direct thermal path to PCB copper. However, its Rth(j-a) = 200 K/W in free air is higher than DO-214AB, so proper PCB copper pour under the cathode pad is essential for sustained surge duty cycles.
Does PTVS58VP1UP-QX require derating at elevated ambient temperatures?
Yes. Rated peak pulse power decreases with junction temperature: at 125 °C, PPPM drops to ~70 % of 600 W (≈420 W), per Figure 2 in the datasheet. Designers must apply thermal derating curves and ensure Tj remains ≤150 °C using layout techniques (e.g., thermal vias, copper area) and worst-case ambient assumptions.
