Product details
Overview
PTVS30VS1UTR from Nexperia is a unidirectional 400 W Transient Voltage Suppressor (TVS) in SOD123W package, designed for high-temperature transient overvoltage protection in power rails. It features 30 V reverse standoff voltage (VRWM), 48.4 V clamping voltage (VCL) at 5 mA, 34.4 A peak pulse current (IPPM), and operates up to 185 °C junction temperature.
For engineers reviewing the PTVS30VS1UTR datasheet, PTVS30VS1UTR pinout, PTVS30VS1UTR application, or PTVS30VS1UTR equivalent, this device serves as a robust, surface-mount solution for industrial power supply surge suppression where thermal stability and low-profile packaging are critical.
Technical Context
This TVS diode uses an avalanche breakdown mechanism to clamp transient voltages above its reverse standoff threshold. Its unidirectional configuration allows conduction only during negative transients relative to cathode, making it suitable for DC rail protection with polarity-sensitive placement.
It complies with IEC 61643-321 (10/1000 μs waveform) and supports ESD immunity up to 30 kV (contact discharge). Thermal resistance from junction to solder point is 18 K/W, enabling reliable operation under sustained high-temperature ambient conditions up to +185 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 30 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe DC blocking range. |
| VCL @ IPPM | 48.4 V - Clamped voltage at 34.4 A peak pulse current; determines maximum stress on downstream circuitry during surge. |
| PPPM | 400 W - Peak pulse power handling per IEC 61643-321 (10/1000 μs); enables robust protection against lightning-induced surges. |
| IRM | 0.001 μA - Reverse leakage at VRWM; ensures minimal standby power loss and signal integrity in high-impedance circuits. |
| Tj max | 185 °C - Maximum junction temperature rating; supports operation in under-hood, motor drive, and industrial control environments. |
| Rth(j-sp) | 18 K/W - Junction-to-solder-point thermal resistance; enables effective heat transfer to PCB copper for sustained pulse duty cycles. |
Pinout & Package
SOD123W (CFP3) plastic surface-mount package: 2.6 mm × 1.7 mm × 1.0 mm body height; marking bar denotes cathode; optimized for reflow and wave soldering with defined footprint per Fig. 6–7.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., +VOUT); conducts during negative transients to shunt surge current to ground. |
| 2 | Anode (A) | Connected to reference potential (e.g., GND); completes conduction path when reverse voltage exceeds VRWM. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction rated to 185 °C - eliminates derating concerns in engine control units, industrial PLCs, and solar inverters. |
| Low-profile SMD package | 1.0 mm max height - enables use in space-constrained power modules and dense PCB layouts without mechanical interference. |
| Low leakage current | 1 nA at VRWM - preserves battery life in always-on systems and avoids false triggering in high-impedance sensing nodes. |
| IEC 61000-4-2 ESD rating | 30 kV contact discharge - exceeds industrial immunity requirements without external ESD staging components. |
Applications
| Industrial Power Supply Protection | Motor Drive DC Bus Protection |
|---|---|
|
Use Scenario: Protecting 24–48 V DC input rails in programmable logic controllers (PLCs) against load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and chassis ground to clamp fast-rising surges within 1 ns response time. Use Value: Limits voltage excursion to ≤48.4 V during 34.4 A transients, preventing damage to upstream DC-DC converters and microcontrollers. |
Use Scenario: Safeguarding the high-side DC link of 3-phase inverter stages in HVAC compressors and servo drives. IC Role / Device Role / Timing Role: Mounted across bus capacitor terminals to absorb regenerative energy spikes during rapid IGBT turn-off.

| Solar Inverter PV Input Protection | Automated Test Equipment (ATE) Power Rails |
|
Use Scenario: Shielding photovoltaic string inputs from lightning-induced surges in outdoor-mounted inverters. IC Role / Device Role / Timing Role: First-line defense on MPPT input stage, positioned before filtering and isolation circuitry. Use Value: 30 V VRWM matches typical open-circuit PV voltage ranges; 48.4 V VCL ensures MOSFET gate drivers remain within safe SOA limits. |
Use Scenario: Securing ±12 V and +5 V analog/digital supply rails in precision ATE systems exposed to relay bounce and cable ESD events. IC Role / Device Role / Timing Role: Localized TVS at each power entry point to suppress sub-100 ns transients before reaching sensitive DACs and ADCs. Use Value: 1 nA leakage prevents offset drift in µV-level measurement paths; 1 mm profile avoids interference with adjacent test fixtures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | Lower PPPM (400 W same), but higher VCL (48.4 V vs. 49.0 V), lower Tj max (150 °C vs. 185 °C), SMA package (2.4 mm height). | Not rated for >150 °C ambient; unsuitable for under-hood or high-temp industrial enclosures. | Select when cost sensitivity outweighs thermal margin and board height is not constrained. |
| SMCJ30A | Higher PPPM (1500 W), larger DO-214AB package (4.5 mm height), same VRWM/VCL, Tj max = 175 °C. | Overqualified for 400 W needs; occupies 3× PCB area; better for multi-pulse or high-energy lightning events. | Select only if system-level surge testing requires >1 kW pulse handling or legacy footprint compatibility is mandatory. |
Compared with SMAJ30A and SMCJ30A, PTVS30VS1UTR delivers superior thermal resilience (185 °C vs. 150/175 °C) and ultra-low profile (1.0 mm), making it optimal for next-generation compact, high-temperature power electronics where space and thermal headroom are simultaneously constrained.

FAQ
What is the maximum clamping voltage of PTVS30VS1UTR at its rated peak pulse current?
The clamping voltage (VCL) is 48.4 V at 34.4 A peak pulse current (IPPM), measured per IEC 61643-321 10/1000 μs waveform. This value is guaranteed across the full operating temperature range (−55 °C to +185 °C) and defines the upper voltage limit imposed on protected circuitry during surge events.
Can PTVS30VS1UTR be used in bidirectional protection configurations?
No - PTVS30VS1UTR is strictly unidirectional. Its internal structure conducts only when the cathode is more positive than the anode by ≥30 V. For bidirectional protection, two devices must be connected in series opposition, or a dedicated bidirectional TVS (e.g., PTVS30VS1UR) must be selected.
How does the 185 °C junction rating impact PCB layout and thermal design?
The 185 °C rating allows uninterrupted operation at ambient temperatures up to 185 °C when mounted per recommended footprint (Fig. 6), provided the junction-to-solder-point thermal resistance (18 K/W) is maintained. Layout must use ≥1 cm² cathode pad copper area on FR4 to achieve specified Rth(j-sp); insufficient copper raises junction temperature beyond rating.
Is PTVS30VS1UTR automotive qualified?
No - this device is not AEC-Q200 qualified. While its 185 °C rating meets under-hood temperature requirements, Nexperia explicitly states in Section 14 that non-automotive qualified products are not tested or warranted for automotive use. Automotive designs require explicit AEC-Q200 certified variants such as PTVS30VS1UTR-Q.
