Product details
Overview
PTVS20VP1UTP,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 = 20 V, VBR(min) = 22.2 V, VCL = 32.4 V at IPPM = 18.5 A (10/1000 µs), and Tj ≤ 185 °C - used in industrial power supply rails and high-reliability DC input stages.
For engineers reviewing the PTVS20VP1UTP,115 datasheet, PTVS20VP1UTP,115 pinout, PTVS20VP1UTP,115 application, or PTVS20VP1UTP,115 equivalent, key selection criteria include clamping voltage under 33 V at 18.5 A, thermal resistance to solder point of 12 K/W, AEC-Q101 qualification status per revision history, and compatibility with FR4 PCB layouts using standard CFP5 reflow footprints.
Technical Context
This TVS diode operates as a unidirectional clamping device, triggered when reverse voltage exceeds 20 V standoff level, with breakdown occurring at minimum 22.2 V and clamping at 32.4 V under 18.5 A peak pulse current (10/1000 µs). Its junction temperature rating up to 185 °C enables deployment in under-hood automotive modules and industrial motor drives where ambient temperatures exceed 150 °C.
Thermal design relies on low Rth(j-sp) = 12 K/W to cathode solder point, enabling effective heat transfer to copper pour without heatsinking. The SOD128 package's 1 mm height and 3.8 mm × 2.6 mm footprint support dense layout in space-constrained DC-DC input filters and battery management system front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 20 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin for 24 V nominal systems. |
| VBR (min) | 22.2 V - guaranteed breakdown onset at 10 mA test current; ensures reliable triggering above VRWM with margin. |
| VCL @ IPPM | 32.4 V - clamped voltage at 18.5 A peak pulse (10/1000 µs); limits downstream IC stress during surge events. |
| PPPM | 600 W - rated peak pulse power per IEC 61643-321; supports robust protection against lightning-induced surges. |
| IRM | 0.001 µA - reverse leakage at VRWM; negligible power loss and signal integrity impact in high-impedance sensing paths. |
| Tj max | 185 °C - maximum junction temperature; enables operation in engine control units and industrial inverters without derating. |
| Rth(j-sp) | 12 K/W - thermal resistance to cathode solder point; allows direct thermal coupling to PCB copper for passive cooling. |
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 indicates cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected circuit ground or low-side reference; carries full surge current during clamping. |
| 2 | Anode (A) | Connected to line being protected (e.g., 24 V rail); reverse-biased during normal operation, forward-conducting during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Qualified per Automotive Electronics Council standard for discrete semiconductors - validated for automotive-grade reliability despite revision history note on qualification scope. |
| High-temperature stability | Junction temperature rating up to 185 °C supports uninterrupted operation in under-hood ECUs and industrial motor drives without thermal shutdown. |
| Low-profile SMD package | 1 mm height enables use in ultra-thin power modules and stacked PCB assemblies where Z-axis clearance is constrained. |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2) and >8 kV HBM rating protect against handling and system-level ESD events without external shielding. |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ20A | Lower PPPM (400 W), higher VCL = 32.4 V at lower IPPM (12.3 A), SMC package (2.5 mm height). | Limited to lower-energy transients; unsuitable for sustained 600 W surges or space-constrained 1 mm Z-height designs. | Select only if cost sensitivity outweighs peak power and profile requirements. |
| SMCJ20A | Same PPPM (1500 W), larger SMC package (7.1 mm × 6.2 mm × 2.6 mm), VCL = 32.4 V at 46.5 A. | Higher surge capacity but incompatible with SOD128 footprint and thermal interface; requires board redesign. | Choose when system-level surge threat exceeds 600 W and board space permits larger package. |
Compared with SMAJ20A and SMCJ20A, PTVS20VP1UTP,115 uniquely balances 600 W surge capability, 1 mm profile, and 12 K/W thermal resistance - making it optimal for compact, high-temperature industrial and automotive modules where both space and thermal performance are critical.

FAQ
Is PTVS20VP1UTP,115 still AEC-Q101 qualified?
Yes - according to the revision history in the December 2025 datasheet, PTVS20VP1UTP is explicitly listed among the 33 products retained under standard AEC-Q101 qualification. This confirms its suitability for automotive applications including body control modules and power distribution units, provided system-level validation is completed.
What is the maximum surge current PTVS20VP1UTP,115 can handle?
At VRWM = 20 V, PTVS20VP1UTP,115 delivers IPPM = 18.5 A under the standardized 10/1000 µs waveform per IEC 61643-321. This corresponds to its full 600 W peak pulse power rating, verified at Tj = 25 °C and scalable per Fig. 2's derating curve up to 185 °C junction temperature.
How does the SOD128 package affect thermal performance?
The SOD128 (CFP5) package achieves Rth(j-sp) = 12 K/W to the cathode solder point - significantly lower than industry-standard SMA or SMB packages - due to its wide cathode tab and optimized internal die attach. This enables efficient heat transfer directly into PCB copper, eliminating need for thermal vias in many high-reliability applications.
Can PTVS20VP1UTP,115 replace PTVS20VP1UTP without changes?
Yes - the suffix ",115" denotes the tape-and-reel packaging variant per Nexperia's ordering convention (e.g., PTVS20VP1UTP,115 = 3,000 pcs/reel, 12 mm tape). Electrical, thermal, and mechanical specifications are identical to base part PTVS20VP1UTP; no schematic or layout modifications are required for substitution.
