Product details
Overview
PTVS54VS1UR,115 from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W (CFP3) package, designed for clamping transient overvoltages on DC power rails. It features VRWM = 54 V, VBR(min) = 60.0 V, VCL(max) = 87.1 V at IPPM = 4.6 A (10/1000 µs), and IRM ≤ 0.001 µA - enabling robust protection of 48 V automotive and industrial power supplies against ISO 7637-2 pulses and ESD.
For engineers reviewing the PTVS54VS1UR,115 datasheet, PTVS54VS1UR,115 pinout, PTVS54VS1UR,115 application, or PTVS54VS1UR,115 equivalent, this device is selected for high-reliability 54 V rail protection where low leakage, sub-1 mm profile, and AEC-Q101 qualification are required - especially in engine control units, battery management systems, and industrial PLC I/O modules.
Technical Context
This unidirectional TVS operates as a clamping diode: reverse-biased under normal operation (VRWM = 54 V), it avalanches at VBR ≥ 60.0 V to divert surge current away from downstream circuitry. Its 10/1000 µs waveform compliance per IEC 61643-321 ensures standardized surge immunity testing validity.
The SOD123W package delivers Rth(j-a) = 220 K/W (FR4, single-sided copper) and Rth(j-sp) = 18 K/W (cathode solder point), supporting thermal dissipation during repetitive transients. The cathode-marked anode-cathode configuration enables straightforward series placement on positive supply lines with polarity-sensitive mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 54 V - maximum continuous reverse operating voltage before clamping begins; sets safe margin above nominal 48 V system rail. |
| VBR (min) | 60.0 V - guaranteed avalanche onset voltage at 1 mA; ensures reliable triggering before downstream IC damage thresholds. |
| VCL (max) | 87.1 V - peak clamped voltage at IPPM = 4.6 A (10/1000 µs); defines worst-case overvoltage seen by protected load. |
| PPPM | 400 W - rated peak pulse power handling capability; supports high-energy transients like load dump (ISO 7637-2 Pulse 5a). |
| IRM | ≤ 0.001 µA - ultra-low reverse leakage at VRWM; prevents measurable quiescent current drain in always-on 48 V systems. |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2); provides system-level ESD robustness without additional protection stages. |
| Package | SOD123W (CFP3) - 2.6 × 1.7 × 1.0 mm surface-mount footprint with 1 mm height; enables dense PCB layouts in space-constrained ECUs. |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2-terminal, flat lead, cathode-bar marked; dimensions 2.6 mm × 1.7 mm × 1.0 mm; FR4-compatible reflow footprint per Nexperia sod123w_fr.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., +48 V rail); marking bar identifies this terminal; carries full surge current during clamping. |
| 2 | Anode (A) | Connected to ground or lower-potential reference; completes current path during transient; must be low-inductance ground plane connection. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability (temperature cycling, HTRB, ESD) - suitable for under-hood and chassis applications. |
| 400 W peak pulse power | Handles ISO 7637-2 Pulse 5a (load dump) up to 120 V/350 ms without failure when properly heatsinked. |
| 0.001 µA max reverse leakage | Enables use in always-on 48 V subsystems (e.g., ADAS sensors) without compromising battery standby life. |
| 1 mm package height | Allows placement beneath connectors or shields in compact power modules and motor controllers. |
| Clamping voltage ≤ 87.1 V | Keeps protected 54 V-rated components (e.g., CAN transceivers, MCU I/O) within absolute maximum ratings during surge events. |
Applications
| Automotive Power Rail Protection | Industrial 48 V DC Power Distribution |
|---|---|
|
Use Scenario: Protecting 48 V battery-fed engine control unit (ECU) inputs from load dump transients during alternator regulation failure. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed directly at ECU power entry point, conducting only during overvoltage events >60 V. Use Value: Limits transient voltage to ≤87.1 V, preventing latch-up or gate oxide rupture in 54 V-rated power management ICs and microcontrollers. |
Use Scenario: Safeguarding programmable logic controller (PLC) analog input modules powered from centralized 48 V DC bus against switching surges and lightning-induced coupling. IC Role / Device Role / Timing Role: Standoff-mode protector on module's VDD rail; responds within nanoseconds to clamp 10/1000 µs transients. Use Value: Maintains signal integrity and prevents false triggering in precision ADCs by suppressing overshoot before it propagates into sensitive analog front-ends. |
| Telecom Remote Radio Unit (RRU) Power Input | EV Onboard Charger Auxiliary Supply |
|
Use Scenario: Securing 48 V DC input of outdoor 5G remote radio units exposed to induced surges from nearby lightning strikes. IC Role / Device Role / Timing Role: First-line transient suppressor upstream of DC-DC converters; absorbs energy before reaching isolation barriers. Use Value: Withstands 30 kV ESD contact discharge and repeated 400 W surges, reducing field failure rates in harsh environmental deployments. |
Use Scenario: Protecting auxiliary 48 V supply rail in electric vehicle onboard chargers that interface with 12 V vehicle networks and external charging infrastructure. IC Role / Device Role / Timing Role: Bidirectional surge suppression not applicable - this unidirectional device guards positive rail only, requiring complementary design for negative transients. Use Value: Enables compact, AEC-Q101-compliant protection matching OEM requirements for EV power electronics without increasing board area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ54A | Same VRWM (54 V), but lower PPPM = 400 W (same rating), higher VCL = 87.9 V, larger SMA package (4.5 × 2.7 × 2.2 mm). | Not AEC-Q101 qualified; intended for commercial/industrial use only. | Select when automotive qualification is unnecessary and board space allows larger footprint. |
| SMCJ54A | Higher PPPM = 1500 W, same VRWM, VCL = 87.1 V, but SMC package (7.1 × 6.2 × 2.6 mm) - 7× larger volume than SOD123W. | Supports higher-energy transients (e.g., ISO 16750-2) but incompatible with space-constrained automotive modules. | Select only if surge threat exceeds 400 W capability and mechanical envelope permits SMC size. |
Compared with SMAJ54A and SMCJ54A, PTVS54VS1UR,115 uniquely combines AEC-Q101 qualification, 1 mm height, and 400 W capability in the smallest possible footprint - making it the preferred choice for next-generation 48 V automotive ECUs where volume and reliability are co-constrained.

FAQ
Is PTVS54VS1UR,115 suitable for bidirectional transient protection?
No. PTVS54VS1UR,115 is a unidirectional TVS diode, meaning it conducts only when reverse-biased beyond its breakdown voltage. It does not protect against negative-going transients on the protected line. For bidirectional protection, a separate device such as PTVS54VS1UR,115 paired with a series diode or a dedicated bidirectional TVS (e.g., PTVS54VS1UTR) is required.
What is the maximum junction temperature and how does it affect power handling?
The absolute maximum junction temperature is 150 °C. As shown in Figure 2 of the datasheet, PPPM derates linearly above 25 °C ambient - at 125 °C Tj, rated peak pulse power drops to approximately 60 % of 400 W (~240 W). Thermal design must ensure adequate PCB copper area and low Rth(j-a) to maintain Tj ≤ 150 °C during surge events.
Does the "115" suffix indicate tape-and-reel packaging?
Yes. Per Nexperia ordering conventions, the "115" suffix denotes 3,000-piece 8 mm tape-and-reel packaging (EIA-481 compliant), standard for SOD123W devices. This format supports automated SMT placement and is compatible with industry-standard pick-and-place equipment used in high-volume automotive electronics manufacturing.
How does the 0.001 µA IRM specification impact system-level power budgeting?
At VRWM = 54 V, IRM ≤ 0.001 µA translates to ≤54 pW of leakage power - negligible in all practical 48 V systems. This enables use in always-on domains (e.g., vehicle keep-alive circuits, telematics wake-up receivers) without measurable impact on battery drain, even over 10+ year service life.
