Product details
Overview
PTVS48VP1UTP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature transient overvoltage protection with VRWM = 48 V, VBR(min) = 53.3 V, VCL = 77.4 V at IPPM = 7.8 A (10/1000 μs), and junction temperature rating up to 185 °C - deployed in industrial power supply rails and high-reliability DC bus lines.
For engineers reviewing the PTVS48VP1UTP,115 datasheet, PTVS48VP1UTP,115 pinout, PTVS48VP1UTP,115 application, or PTVS48VP1UTP,115 equivalent, key selection criteria include clamping voltage under 78 V at 7.8 A, thermal resistance as low as 12 K/W (junction-to-solder point), reverse leakage ≤ 0.001 μA at VRWM, AEC-Q101 qualification status per revision history, and compatibility with reflow/wave soldering footprints for SOD128.
Technical Context
This unidirectional TVS diode operates in avalanche breakdown mode to clamp transients above its reverse standoff voltage (VRWM = 48 V), with a typical breakdown voltage range of 53.3–58.9 V at 1 mA. Its clamping behavior follows IEC 61643-321 (10/1000 μs waveform), delivering 77.4 V clamping voltage at 7.8 A peak pulse current.
Thermal design is enabled by low-profile SOD128 packaging (1 mm height) and multiple thermal resistance options: 200 K/W (free air), 60 K/W (ceramic PCB), and 12 K/W (junction-to-solder point). It maintains stable PPPM = 600 W up to Tj = 150 °C, with relative pulse power dropping to ~80% at 185 °C per Fig. 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 48 V - maximum continuous reverse operating voltage before clamping initiates; defines safe DC bias margin in protected line. |
| VBR (min) | 53.3 V - minimum breakdown voltage at 1 mA; ensures reliable turn-on above VRWM with ≥5.3 V design margin. |
| VCL @ IPPM | 77.4 V at 7.8 A - clamped voltage during 10/1000 μs surge; determines maximum stress on downstream ICs. |
| PPPM | 600 W - peak pulse power handling (IEC 61643-321); supports robust protection against lightning-induced surges. |
| IRM | ≤ 0.001 μA at VRWM - ultra-low reverse leakage; minimizes standby power loss in battery-backed or low-power systems. |
| Tj max | 185 °C - maximum junction temperature; enables operation in under-hood automotive or industrial motor drive environments. |
| Rth(j-sp) | 12 K/W - junction-to-solder-point thermal resistance; allows effective heat transfer to PCB copper when cathode pad is sized per Fig. 7. |
Pinout & Package
SOD128 (CFP5) plastic surface-mounted package: 2-terminal, flat lead, 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm pitch, marking bar denotes cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line's positive rail; carries surge current into ground path during clamping event. |
| 2 | Anode (A) | Connected to system ground; completes conduction path during transient; must be low-inductance for fast response. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Qualified per revision history v.2 (Dec 2025); supports deployment in automotive subsystems where reliability is mandated. |
| High-temperature stability | Rated for continuous operation up to Tj = 185 °C; maintains clamping performance without derating in hot ambient zones. |
| Low-profile SMD package | 1 mm height SOD128 footprint enables dense layout in space-constrained power modules and motor controllers. |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2) and >8 kV HBM; protects against handling and system-level ESD events. |
| Controlled thermal path | 12 K/W Rth(j-sp) enables predictable thermal design using standard FR4 PCB with optimized cathode pad area (1 cm²). |
Applications
| Industrial Power Supply Protection | Motor Drive DC Bus Clamping |

| Telecom Remote Radio Unit (RRU) | Energy Storage System (ESS) BMS Interface |
|
Use Scenario: 48 V backplane power input of outdoor 5G remote radio unit subject to lightning-induced surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp on power entry, coordinated with upstream fuse and downstream π-filter. Use Value: 30 kV ESD rating and 600 W pulse capability meet IEC 61000-4-5 Level 4 requirements for outdoor telecom infrastructure. |
Use Scenario: Signal/power interface between 48 V battery stack and BMS monitoring ICs in lithium-ion energy storage cabinets. IC Role / Device Role / Timing Role: Bidirectional protection not required; unidirectional TVS guards against polarity-reversal and charge pump overshoot.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ48A | Lower PPPM = 400 W; VRWM = 48 V; VCL = 77.4 V at 5.2 A; SMC package (2.4 mm height). | Not qualified to AEC-Q101; higher Rth(j-a) = 50 K/W; unsuitable for 185 °C ambient or automotive use. | Select only if cost sensitivity outweighs thermal and qualification requirements; verify PCB thermal relief for SMC footprint. |
| SMCJ48A | PPPM = 1500 W; VRWM = 48 V; VCL = 77.4 V at 19.4 A; same SMC package; Tj max = 175 °C. | Higher surge capacity but larger footprint and 0.5 °C/W higher Rth(j-a); no AEC-Q101 status in latest revision. | Prefer for extreme surge environments (e.g., railway traction); avoid where board space or automotive compliance is critical. |
Compared with SMAJ48A and SMCJ48A, PTVS48VP1UTP,115 delivers identical clamping voltage at lower peak current while enabling smaller board area, superior high-temperature operation (185 °C vs. 175 °C), and verified AEC-Q101 qualification - making it optimal for space- and reliability-constrained 48 V industrial and automotive subsystems.

FAQ
Is PTVS48VP1UTP,115 AEC-Q101 qualified?
Yes - per the December 2025 revision history (v.2), PTVS48VP1UTP,115 is explicitly listed among the 33 types upgraded to standard AEC-Q101 qualification. This confirms stress-test validation for automotive-grade reliability, including temperature cycling, humidity testing, and ESD robustness per Q101 requirements.
What is the maximum clamping voltage at rated peak pulse current?
The clamping voltage VCL is 77.4 V at IPPM = 7.8 A under 10/1000 μs waveform conditions (Table 8). This value is measured at Tj = 25 °C; actual clamping may rise slightly at elevated junction temperatures but remains within specification limits up to 185 °C.
Can PTVS48VP1UTP,115 be used in bidirectional configurations?
No - it is a unidirectional TVS diode with anode and cathode terminals. For bidirectional protection, two devices must be connected in series opposing configuration, or a dedicated bidirectional part like PTVS48VP1UTP,115's counterpart in the PTVS48VU1UTP series should be selected.
What PCB layout guidance applies to optimize thermal performance?
Per Figure 7, use a 1 cm² cathode solder pad on FR4 with tin plating to achieve Rth(j-sp) = 12 K/W. Avoid thermal reliefs on the cathode pad; ensure uninterrupted copper connection to internal ground planes. Anode pad may be smaller but must maintain low inductance for fast transient response.
