Product details
Overview
PTVS5V0S1UR/8X from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for clamping transient overvoltages on low-voltage DC rails. It features a 5.0 V reverse standoff voltage (VRWM), 6.4–7.0 V breakdown voltage (VBR), 9.2 V clamping voltage (VCL) at 43.5 A peak pulse current (IPPM), and 0.001 µA reverse leakage at VRWM - optimized for protecting 5 V power supplies in industrial control modules.
For engineers reviewing the PTVS5V0S1UR/8X datasheet, PTVS5V0S1UR/8X pinout, PTVS5V0S1UR/8X application, or PTVS5V0S1UR/8X equivalent, this device is selected for precise 5 V rail protection where low clamping voltage, sub-1 mm profile, and AEC-Q101 qualification (per revision v.4) are critical to system-level ESD and surge resilience.
Technical Context
This unidirectional TVS operates as a silicon avalanche diode, triggered when transient voltage exceeds its 5.0 V standoff threshold, entering low-impedance conduction to divert up to 400 W (10/1000 µs waveform per IEC 61643-321). Its cathode-anode polarity requires correct PCB orientation to ensure forward-biased clamping during positive transients.
Thermal performance is defined by junction-to-solder-point resistance of 18 K/W and junction-to-ambient of 70 K/W on ceramic PCB - enabling reliable operation up to 150 °C junction temperature under repetitive surge conditions typical in motor drive power stages and sensor interface circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.0 V - maximum continuous reverse operating voltage before clamping begins; matches standard 5 V logic and supply rails. |
| VBR (min/typ/max) | 6.4 / 6.7 / 7.0 V at IR = 10 mA - tight 0.6 V window ensures predictable turn-on with minimal overshoot. |
| VCL | 9.2 V at IPPM = 43.5 A - limits transient voltage to safe levels for downstream 5 V ICs like microcontrollers and CAN transceivers. |
| PPPM | 400 W (10/1000 µs) - handles high-energy surges such as ISO 7637-2 Pulse 1/2a/5a without degradation. |
| IRM | 0.001 µA at VRWM - negligible leakage preserves battery life in always-on 5 V monitoring circuits. |
| Package | SOD123W (CFP3): 2.6 × 1.7 × 1.0 mm - ultra-low profile enables placement near connectors and IC power pins. |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2) - withstands direct ESD events without failure or parameter shift. |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2-terminal, flat lead, single-sided copper footprint compatible with reflow and wave soldering per Nexperia's recommended land patterns (Fig. 6 & 7). Marking bar denotes cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., 5 V rail); clamps positive transients to ground via anode connection. |
| 2 | Anode (A) | Connected to circuit ground; completes low-impedance path during avalanche conduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability (per revision v.4), supporting deployment in engine control units and body electronics despite non-automotive marking status in earlier revisions. |
| 1 mm max height | Enables placement under shields or in space-constrained areas such as USB-C PD port protection and IoT sensor node PCBs. |
| Low VCL/VBR ratio | 9.2 V / 6.7 V ≈ 1.37 - superior clamping efficiency vs. competing 5 V TVS diodes (typical ratio >1.45), reducing stress on protected ICs. |
| High IPPM | 43.5 A peak pulse current - sustains multiple 400 W surges without parametric drift, critical for industrial HMI front-panel interfaces. |
| 0.001 µA IRM | Ensures <1 nA leakage at 5 V - avoids measurable loading on precision voltage references or low-power sleep-mode regulators. |
Applications
| Industrial PLC I/O Module Protection | USB 2.0 Data Line ESD Clamp |
|---|---|
Use Scenario: Protecting 5 V digital input channels in programmable logic controllers exposed to field wiring-induced surges (IEC 61000-4-4, 4 kV). IC Role / Device Role / Timing Role: Unidirectional TVS placed between input terminal and 5 V rail, clamping fast-rising transients before they reach optocoupler or MCU GPIO. Use Value: 9.2 V clamping ensures MCU inputs remain below absolute maximum rating (typically 5.5 V) even during 43.5 A surge, preventing latch-up or permanent damage. |
Use Scenario: ESD protection on D+ and D− lines of embedded USB 2.0 host ports in medical diagnostic equipment. IC Role / Device Role / Timing Role: Bidirectional protection not required; unidirectional PTVS5V0S1UR/8X used on VBUS line only, while data lines use dedicated low-capacitance TVS. Use Value: 30 kV contact ESD rating meets IEC 61000-4-2 Level 4, and 1 mm height allows placement adjacent to USB connector without interfering with shield can. |
| Automotive Body Control Module (BCM) Power Rail | Smart Meter 5 V Auxiliary Supply |
Use Scenario: Secondary overvoltage protection on 5 V auxiliary rail powering LIN transceivers and LED drivers in BCMs. IC Role / Device Role / Timing Role: Standoff at 5.0 V ensures no conduction during normal operation; activates within <1 ns when load dump or inductive kick exceeds 6.4 V. Use Value: AEC-Q101 qualification (v.4) confirms robustness across -40 °C to +125 °C ambient, and 400 W PPPM handles ISO 7637-2 Pulse 5a (12 V systems). |
Use Scenario: Protecting isolated 5 V DC-DC output supplying metrology ICs and RTC in utility smart meters. IC Role / Device Role / Timing Role: Placed directly at DC-DC converter output capacitor, shunting transients induced by relay switching or lightning-induced coupling on AC mains input. Use Value: 0.001 µA IRM prevents measurable current drain on backup coin cell during power outage, extending meter battery life beyond 10 years. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | DO-214AC package (4.5 × 2.7 × 2.2 mm); 600 W PPPM; higher VCL = 9.6 V at 43.3 A. | Larger footprint and 2.2× height limit placement near fine-pitch connectors; higher clamping increases stress on 5 V ICs. | Choose SMAJ5.0A only if higher surge rating is mandatory and board space permits larger package. |
| 1.5SMC5.0A | DO-214AB package (7.2 × 6.2 × 2.6 mm); 1500 W PPPM; VCL = 9.2 V at 163 A; 10× larger volume. | Over-specified for 5 V rail protection; excessive size incompatible with modern compact designs like smart sensors or wearables. | Select 1.5SMC5.0A only for legacy industrial panels where PCB real estate is unconstrained and 1.5 kW surge immunity is required. |
Compared with SMAJ5.0A and 1.5SMC5.0A, PTVS5V0S1UR/8X delivers identical 5 V protection functionality in a 75% smaller footprint and 1 mm height - making it optimal for space- and height-sensitive 5 V applications where 400 W surge handling suffices.

FAQ
What is the maximum clamping voltage of PTVS5V0S1UR/8X under rated surge conditions?
The clamping voltage (VCL) is 9.2 V measured at 43.5 A peak pulse current (IPPM), per IEC 61643-321 10/1000 µs waveform. This value is guaranteed across the full operating temperature range (-55 °C to +150 °C) and represents the maximum voltage seen by protected circuitry during a 400 W transient event.
Is PTVS5V0S1UR/8X suitable for bidirectional signal line protection?
No - PTVS5V0S1UR/8X is a unidirectional TVS diode intended only for DC power rail protection. It conducts only during positive transients relative to ground. For bidirectional data lines (e.g., RS-485, CAN), a symmetric bipolar TVS or dedicated bidirectional array must be used instead.
Does the SOD123W package support automated optical inspection (AOI) after reflow?
Yes - the SOD123W package has a visible cathode marking bar and consistent solder joint geometry compatible with standard AOI systems. Nexperia's recommended reflow footprint (Fig. 6) ensures ≥95% solder paste transfer and uniform wetting, enabling reliable defect detection for voids, bridging, and tombstoning.
How does the AEC-Q101 qualification status apply to PTVS5V0S1UR/8X?
Per revision v.4 of the datasheet (issued December 2025), PTVS5V0S1UR/8X is explicitly included in the list of 33 types upgraded to standard AEC-Q101 qualification. This covers temperature cycling, humidity bias, ESD, and surge testing per AEC-Q101-004/005/011, confirming suitability for automotive power electronics.
