Product details
Overview
PTVS58VS1UTR-Q from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for high-temperature transient overvoltage protection in automotive 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.
For engineers reviewing the PTVS58VS1UTR-Q datasheet, PTVS58VS1UTR-Q pinout, PTVS58VS1UTR-Q application, or PTVS58VS1UTR-Q equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance data, clamping behavior under IEC 61643-321 stress, and real-world automotive power rail protection use cases.
Technical Context
This TVS diode operates in reverse-biased mode with cathode-anode polarity, triggering avalanche breakdown above VRWM to clamp transients. Its unidirectional architecture provides low-leakage (<0.001 µA at VRWM) and precise voltage threshold control across temperature.
It complies with IEC 61643-321 (10/1000 µs waveform), supports ESD immunity up to ±30 kV (IEC 61000-4-2 contact/air), and maintains stable PPPM performance up to 185 °C junction temperature per Fig. 2 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 58 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin for 48 V automotive systems. |
| VBR (min) | 64.4 V at 1 mA - Minimum breakdown voltage ensures reliable turn-on above nominal rail; guarantees clamping activation during load dump events. |
| VCL | 93.6 V at IPPM = 4.3 A (10/1000 µs) - Peak clamped voltage seen by protected circuit; limits downstream IC stress during ISO 7637-2 Pulse 5a. |
| PPPM | 400 W - Rated peak pulse power per IEC 61643-321; enables robust suppression of high-energy transients without thermal runaway. |
| IRM | 0.001 µA at VRWM - Ultra-low reverse leakage preserves battery drain budget in always-on automotive modules. |
| Tj max | 185 °C - Junction temperature rating validated per AEC-Q101; supports under-hood placement near engines or power converters. |
| Rth(j-sp) | 18 K/W - Thermal resistance from junction to solder point; enables effective heat dissipation through PCB copper when mounted per recommended footprint. |
Pinout & Package
SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body height, flat lead profile optimized for automated assembly and low-profile board layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., 48 V rail); marking bar on device body identifies this terminal; carries full transient current during clamping. |
| 2 | Anode (A) | Connected to ground reference; forms low-impedance path to earth during overvoltage events; requires low-inductance PCB routing. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Stress-tested per Automotive Electronics Council standard for discrete semiconductors; certified for under-hood and powertrain applications. |
| High-temperature operation | Junction temperature rated to 185 °C; maintains clamping stability and leakage performance beyond standard industrial limits. |
| Low-profile SOD123W package | 1.0 mm maximum height enables integration into space-constrained modules such as ADAS ECUs and battery management systems. |
| ESD robustness | ±30 kV contact discharge (IEC 61000-4-2); protects against human-body and system-level electrostatic events during handling and operation. |
| Low thermal resistance | Rth(j-sp) = 18 K/W to solder point; facilitates efficient heat transfer to PCB copper, supporting sustained pulse handling in thermally dense environments. |
Applications
| Automotive Power Rail Protection | Industrial 48 V DC Distribution |
|---|---|

IC Role / Device Role / Timing Role: Primary overvoltage clamp on main DC input, coordinated with upstream fuses and secondary filtering. Use Value: Withstands repeated 400 W pulses while maintaining <0.001 µA leakage-critical for long-term reliability in sealed enclosures. |
| On-Board Charger Input Stage | High-Temperature Motor Drive Interface |
|
Use Scenario: Safeguarding AC/DC front-end rectifiers in EV on-board chargers exposed to grid surges and regenerative braking feedback. IC Role / Device Role / Timing Role: Fast-acting TVS parallel to bulk capacitor, absorbing energy before it reaches bridge rectifier and controller ICs. Use Value: 185 °C Tj rating allows direct mounting near heatsinks or power inductors without derating. |
Use Scenario: Shielding gate driver supply lines in traction inverter modules operating near electric motors. IC Role / Device Role / Timing Role: Localized clamping at gate driver VDD pin to prevent latch-up during switching-induced coupling. Use Value: Low Rth(j-sp) = 18 K/W enables rapid heat extraction into motor drive PCB copper, sustaining pulse integrity at elevated ambient temperatures. |
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 but higher VCL = 96.8 V at same IPPM; VRWM = 58 V identical; not AEC-Q101 qualified. | Approved for industrial use only; lacks automotive qualification and high-temp thermal validation. | Select only for non-automotive 48 V systems where AEC-Q101 compliance is not required. |
| TPSMD58A | Same VRWM = 58 V and VCL ≈ 93.5 V, but rated for 600 W PPPM; larger SMA package (4.5 mm × 2.7 mm × 2.3 mm). | Higher power handling suits infrequent high-energy surges; increased footprint conflicts with space-constrained automotive modules. | Prefer when surge duty cycle exceeds 1 pulse/minute and board area permits larger SMD package. |
Compared with SMAJ58A-Q and TPSMD58A, PTVS58VS1UTR-Q uniquely combines AEC-Q101 qualification, 1 mm profile, and validated 185 °C operation-making it the only choice for compact, high-reliability automotive 48 V protection where thermal density and qualification are mandatory.

FAQ
What is the maximum clamping voltage of PTVS58VS1UTR-Q under standard test conditions?
The clamping voltage VCL is 93.6 V at IPPM = 4.3 A using the 10/1000 µs waveform per IEC 61643-321. This value is measured at Tj = 25 °C and defines the peak voltage imposed on protected circuitry during worst-case transient events.
Does PTVS58VS1UTR-Q meet automotive qualification standards?
Yes, it is fully qualified to AEC-Q101 for stress testing of discrete semiconductors and explicitly recommended for automotive applications in the official Nexperia datasheet. It supports junction temperatures up to 185 °C and passes ±30 kV ESD tests per IEC 61000-4-2.
How does the SOD123W package affect thermal performance in PCB layout?
The SOD123W (CFP3) package achieves Rth(j-sp) = 18 K/W to the cathode solder point when mounted per Nexperia's recommended footprint. This requires a minimum 1 cm² copper pour under the cathode pad on FR4 PCBs to realize specified thermal resistance and avoid junction overheating during repetitive pulses.
Can PTVS58VS1UTR-Q replace older TVS diodes like P6SMB58A in existing designs?
No direct drop-in replacement: PTVS58VS1UTR-Q uses SOD123W (2.6 × 1.7 mm), while P6SMB58A uses DO-214AA (4.5 × 3.2 mm). Layout redesign is required. However, its lower profile, AEC-Q101 qualification, and superior high-temperature stability make it a strategic upgrade for new automotive platforms.
