Product details
Overview
PTVS20VP1UP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-energy ESD and surge protection on DC power rails. It features VRWM = 20 V, VBR(min) = 22.2 V, VCL(max) = 32.4 V at IPPM = 18.5 A (10/1000 µs), and IRM ≤ 0.001 µA, enabling robust clamping in automotive and industrial power supply circuits.
For engineers reviewing the PTVS20VP1UP,115 datasheet, PTVS20VP1UP,115 pinout, PTVS20VP1UP,115 application, or PTVS20VP1UP,115 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, peak pulse current handling under IEC 61000-4-5 Level 4, thermal resistance to PCB copper area, and compatibility with automated SMT reflow profiles for high-reliability board assembly.
Technical Context
This unidirectional TVS operates as a reverse-biased avalanche diode, triggering when transient voltage exceeds its 20 V standoff threshold and clamping to ≤32.4 V at 18.5 A peak pulse current. Its 1 mm profile and 3.8 mm × 2.6 mm footprint support dense PCB layouts while maintaining 600 W peak pulse power per IEC 61643-321 (10/1000 µs waveform).
Thermal performance is defined by Rth(j-sp) = 12 K/W to cathode solder point and Rth(j-a) = 60 K/W on ceramic PCB - critical for sustained surge duty cycles. ESD robustness includes 30 kV contact discharge (IEC 61000-4-2) and >4 kV HBM, confirming suitability for environments with frequent electrostatic events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - sustains single 10/1000 µs surges up to 600 W without degradation, per IEC 61643-321 |
| Reverse Standoff Voltage | 20 V - maximum continuous DC voltage before significant leakage; sets minimum operating rail margin |
| Breakdown Voltage | 22.2–24.5 V - guaranteed avalanche onset range; ensures reliable turn-on before downstream IC damage |
| Clamping Voltage | 32.4 V max at 18.5 A - limits transient voltage seen by protected circuitry during worst-case surge |
| Reverse Leakage | ≤0.001 µA at 20 V - negligible standby power loss and no measurable impact on low-current sensor rails |
| ESD Rating | 30 kV contact discharge - withstands extreme human-body ESD events without parameter shift or failure |
| Package | SOD128 (CFP5) - 3.8 mm × 2.6 mm × 1.0 mm surface-mount outline with cathode-marked anode-cathode polarity |
Pinout & Package
SOD128 (CFP5) package: plastic surface-mounted device with 2 terminals, 4 mm pitch, 3.8 mm × 2.6 mm body, and 1.0 mm maximum height. Cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected circuit's positive rail; carries full surge current during clamping |
| 2 | Anode (A) | Connected to ground or low-impedance return path; completes conduction loop during transient |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical shock |
| Low-profile SMD package | 1.0 mm height enables use in space-constrained modules such as ADAS ECUs and battery management systems |
| High surge current capability | 18.5 A peak pulse current supports IEC 61000-4-5 Level 4 (4 kV line-to-earth) compliance |
| Ultra-low leakage | 0.001 µA at VRWM minimizes quiescent drain on always-on 20 V auxiliary supplies |
| Optimized thermal path | 12 K/W junction-to-solder-point resistance enables effective heat dissipation via cathode pad copper pour |
Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ20A | DO-214AC package; 400 W PPPM; VCL = 32.4 V at 12.3 A; higher Rth(j-a) = 95 K/W | Larger footprint (4.5 mm × 2.7 mm); less suitable for ultra-thin modules | Preferred where legacy DO-214AC layout exists and 600 W rating is not required |
| SMCJ20A | DO-214AB package; 1500 W PPPM; VCL = 32.4 V at 46.5 A; 2.4 mm height | Higher surge capacity but 2.4× taller; incompatible with 1 mm height constraints | Chosen when system-level testing requires >600 W margin or multi-pulse endurance |
Compared with SMAJ20A and SMCJ20A, PTVS20VP1UP,115 delivers identical clamping performance at 20 V standoff while offering superior height constraint compliance (1.0 mm vs. ≥2.4 mm) and lower thermal resistance to PCB - making it optimal for next-generation compact automotive and industrial modules where vertical space and thermal management are critical.

FAQ
Is PTVS20VP1UP,115 qualified for automotive applications?
Yes - PTVS20VP1UP,115 is AEC-Q101 qualified per the revision history (v.3, December 2025), with 25 variants including this part upgraded to standard automotive qualification status. It has passed stress tests for temperature cycling, humidity, and mechanical shock required for under-hood and body electronics deployment.
What is the maximum clamping voltage at rated peak pulse current?
The maximum clamping voltage is 32.4 V at 18.5 A peak pulse current (IPPM), measured under IEC 61643-321 10/1000 µs waveform conditions at Tj = 25 °C. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
How does the SOD128 package affect thermal performance?
The SOD128 (CFP5) package provides Rth(j-sp) = 12 K/W to the cathode solder point, enabling efficient heat transfer to PCB copper. When mounted on a 1 cm² cathode pad on FR4, Rth(j-a) drops to 60 K/W - significantly better than DO-214 packages - allowing higher surge repetition rates without thermal runaway.
Can PTVS20VP1UP,115 replace older PTVS20Vxx parts?
Yes - PTVS20VP1UP,115 supersedes earlier PTVS20V variants in the same SOD128 package with identical electrical specs and improved qualification status. Marking code "B3" confirms direct compatibility; no layout or schematic changes are needed for drop-in replacement in existing designs.
