Product details
Overview
PTVS58VS1UR-Q from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) diode in SOD123W (CFP3) package, designed for automotive-grade overvoltage clamping on power rails and signal lines. It features VRWM = 58 V, VBR(min) = 64.4 V, VCL(max) = 93.6 V at IPPM = 4.3 A (10/1000 µs), and qualifies to AEC-Q101 for under-hood electronics protection.
For engineers reviewing the PTVS58VS1UR-Q datasheet, PTVS58VS1UR-Q pinout, PTVS58VS1UR-Q application, or PTVS58VS1UR-Q equivalent, key selection criteria include clamping voltage margin relative to system rail, peak pulse current handling under IEC 61643-321 waveform, thermal resistance to solder point (Rth(j-sp) = 18 K/W), and AEC-Q101 qualification status for automotive deployment.
Technical Context
This unidirectional TVS operates as a reverse-biased avalanche clamp: it remains high-impedance below VRWM = 58 V and triggers into low-impedance conduction when transient voltage exceeds VBR(min) = 64.4 V. Its response time is sub-nanosecond, enabling suppression of fast ESD and load-dump spikes.
Rated for 400 W peak pulse power (10/1000 µs), it delivers IPPM = 4.3 A while limiting voltage to VCL(max) = 93.6 V - providing 35.6 V headroom above VRWM. Thermal design leverages Rth(j-sp) = 18 K/W to manage junction temperature rise during repetitive transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 58 V - maximum continuous reverse operating voltage before leakage exceeds 0.1 µA; sets upper limit for protected circuit DC rail. |
| VBR (min) | 64.4 V - minimum breakdown voltage at IR = 1 mA; defines earliest clamping onset under surge conditions. |
| VCL (max) | 93.6 V - maximum clamped voltage at IPPM = 4.3 A (10/1000 µs); determines worst-case stress on downstream ICs. |
| PPPM | 400 W - peak pulse power rating per IEC 61643-321; validates robustness against standardized surge waveforms. |
| IRM | 0.001 µA - reverse leakage at VRWM; ensures negligible standby current draw in battery-sensitive systems. |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact/air); provides immunity to human-body and system-level electrostatic discharge events. |
| Rth(j-sp) | 18 K/W - thermal resistance from junction to cathode solder point; enables effective heat dissipation via PCB copper. |
Pinout & Package
PTVS58VS1UR-Q uses the SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body with 1 mm profile height, optimized for space-constrained automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Marked side with bar; connects to protected line (e.g., 58 V supply rail); carries full surge current during clamping. |
| 2 (A) | Anode | Connects to ground reference; completes low-impedance path for transient energy diversion during avalanche conduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units, body electronics, and ADAS sensors requiring reliability under thermal cycling and vibration. |
| Low-profile SOD123W | 1.0 mm max height enables placement beneath connectors or in tight board-to-board interfaces without mechanical interference. |
| 400 W surge capability | Supports IEC 61000-4-5 Level 4 (4 kV) and ISO 7637-2 Pulse 5a (load dump) compliance with margin. |
| Sub-1 µA leakage | Enables use on always-on battery rails (e.g., CAN standby lines) without measurable parasitic drain over vehicle lifetime. |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Infotainment Display Supply |
|---|---|
Use Scenario: Protects 58 V nominal battery-fed ECU input against load dump transients up to 120 V. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between VIN and GND, clamping within 1 ns after overvoltage detection. Use Value: Limits voltage seen by downstream DC-DC converter to ≤93.6 V, preventing latch-up or gate oxide damage in PMICs. |
Use Scenario: Shields 58 V backlight or display power rail from alternator ripple and ignition noise. IC Role / Device Role / Timing Role: Standoff protector on high-side supply path; blocks reverse current while conducting surges to chassis ground. Use Value: Maintains <0.001 µA leakage to avoid dark-current drift in OLED bias circuits during sleep mode. |
| ADAS Camera Module Interface | Electric Power Steering (EPS) Sensor Line |
Use Scenario: Guards LVDS or FPD-Link III power pins against ESD events during assembly or field service. IC Role / Device Role / Timing Role: Fast-response clamping device on 58 V auxiliary rail feeding image sensor bias circuitry. Use Value: Withstands ±30 kV contact ESD per IEC 61000-4-2 without degradation, preserving signal integrity. |
Use Scenario: Protects torque sensor analog supply in EPS systems exposed to motor commutation noise. IC Role / Device Role / Timing Role: Low-leakage transient suppressor on isolated 58 V sensor excitation line. Use Value: Delivers Rth(j-sp) = 18 K/W thermal path to heatsink pad, sustaining repeated 400 W pulses without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ58A | Same VRWM (58 V), but lower PPPM = 400 W only at 10/1000 µs; VCL = 93.6 V identical; SMC package (higher profile: 2.3 mm). | SMC footprint requires larger PCB area; less suitable for ultra-thin modules like camera housings. | Select when higher thermal mass is needed for infrequent high-energy surges and board space allows SMC. |
| Vishay SMA6J58A | Identical VRWM and VCL; rated PPPM = 600 W (10/1000 µs), but AEC-Q101 not claimed; IRM = 1 µA (1000× higher leakage). | Higher leakage disqualifies use on battery-backed sensor rails; lacks automotive qualification documentation. | Consider only for non-automotive industrial power supplies where leakage and qualification are non-critical. |
Compared with SMAJ58A and SMA6J58A, PTVS58VS1UR-Q uniquely combines AEC-Q101 qualification, 1 mm profile, and sub-µA leakage - making it the sole choice for space-constrained, safety-critical automotive power rail protection.

FAQ
What is the maximum clamping voltage of PTVS58VS1UR-Q under standard test conditions?
The maximum clamping voltage (VCL) is 93.6 V, measured at IPPM = 4.3 A using the 10/1000 µs double-exponential current waveform per IEC 61643-321. This value defines the absolute upper voltage limit imposed on protected circuitry during a full-rated surge event.
Does PTVS58VS1UR-Q support bidirectional transient suppression?
No - PTVS58VS1UR-Q is a unidirectional TVS diode, configured for reverse-biased operation only. It conducts surge current from cathode to anode when voltage exceeds VBR; it does not suppress positive transients on the anode side relative to cathode.
How is the SOD123W package thermally managed during repeated surge events?
Thermal management relies on Rth(j-sp) = 18 K/W - the resistance from junction to cathode solder point. Effective heat transfer requires a minimum 1 cm² copper pour connected to the cathode pad, per Nexperia's recommended layout in the datasheet.
Can PTVS58VS1UR-Q replace PTVS58VS1UR without modification?
Yes - PTVS58VS1UR-Q is the automotive-qualified variant of PTVS58VS1UR, sharing identical electrical characteristics and SOD123W package. The "-Q" suffix denotes AEC-Q101 qualification; no layout or schematic changes are required for drop-in replacement in automotive designs.
