Product details
Overview
PTVS20VP1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at 20 V reverse standoff voltage (VRWM), with clamping voltage VCL = 32.4 V at IPPM = 18.5 A and IRM ≤ 0.001 µA. It delivers AEC-Q101 qualification, 1 mm profile, and IEC 61643-321 (10/1000 µs) compliance for robust ESD and surge immunity in power rails.
For engineers reviewing the PTVS20VP1UP-QX datasheet, PTVS20VP1UP-QX pinout, PTVS20VP1UP-QX application, or PTVS20VP1UP-QX equivalent, key selection criteria include VRWM tolerance (±5%), low thermal resistance (Rth(j-sp) = 12 K/W), cathode-marked polarity, and automotive-grade reliability validation per AEC-Q101 stress tests.
Technical Context
This unidirectional TVS diode operates as a clamping device: under normal bias (VR ≤ VRWM = 20 V), it presents <0.001 µA leakage; during transients exceeding VBR (min 22.2 V), it avalanches to limit voltage across protected circuitry to ≤32.4 V at 18.5 A peak pulse current. Its junction-to-solder-point thermal resistance of 12 K/W enables effective heat dissipation in compact automotive PCB layouts.
The device uses planar silicon junction technology with controlled avalanche breakdown characteristics, qualified per AEC-Q101 for temperature cycling, HBM ESD (8 kV), and IEC 61000-4-2 contact/air discharge (30 kV). Its SOD128 footprint supports high-density placement while maintaining 600 W peak pulse power handling per IEC 61643-321 waveform.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 20 V - Maximum continuous reverse operating voltage before significant leakage; defines safe working range for 24 V automotive systems. |
| VBR (min) | 22.2 V - Minimum breakdown voltage at 10 mA test current; ensures reliable turn-on margin above VRWM. |
| VCL @ IPPM | 32.4 V at 18.5 A - Clamped voltage during 10/1000 µs surge; determines maximum stress on downstream ICs. |
| PPPM | 600 W - Peak pulse power rating per IEC 61643-321; defines transient energy absorption capability. |
| IRM | ≤0.001 µA - Reverse leakage at VRWM; ensures minimal standby power loss in battery-sensitive applications. |
| Rth(j-sp) | 12 K/W - Junction-to-solder-point thermal resistance; enables efficient heat transfer to PCB copper for sustained surge duty. |
| AEC-Q101 | Qualified - Validated for automotive use including temperature cycling, mechanical shock, and ESD stress per AEC standard. |
Pinout & Package
Package: CFP5 (SOD128) - surface-mounted plastic package, 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, cathode marked by bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 24 V rail); marking bar identifies this terminal; reverse-biased during normal operation. |
| 2 (A) | Anode | Connected to ground reference; completes clamping path during overvoltage events; requires low-inductance ground layout. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Enables protection against ISO 7637-2 Pulse 1/2a/5a surges in 12 V/24 V automotive systems without derating. |
| 1 mm package height | Supports ultra-low-profile board stacking in space-constrained ECUs and ADAS modules. |
| AEC-Q101 qualification | Validates reliability for automotive under-hood and infotainment environments (-40 °C to +150 °C junction). |
| 30 kV ESD rating (IEC 61000-4-2) | Eliminates need for additional ESD protection stages in CAN/LIN bus interfaces and sensor inputs. |
| Low Rth(j-sp) = 12 K/W | Reduces thermal stress during repetitive transients, extending lifetime in cyclic load applications like motor drivers. |

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-Q | Lower PPPM (400 W), higher VCL (34.0 V at 17.6 A), same SOD-123 package | Marginally lower surge handling; suitable only for non-load-dump scenarios | Select when cost sensitivity outweighs 600 W requirement and layout space is constrained to SOD-123. |
| SMCJ20A-Q | Higher PPPM (1500 W), larger DO-214AB package (7.11 mm × 6.22 mm), VCL = 32.4 V at 46.5 A | Overqualified for most automotive ECUs; requires more PCB area and thermal mass | Choose only when system-level testing confirms need for >600 W or multi-pulse endurance beyond AEC-Q101 baseline. |
Compared with SMAJ20A-Q and SMCJ20A-Q, PTVS20VP1UP-QX uniquely balances 600 W surge capacity, SOD128's 1 mm height, and AEC-Q101 qualification-making it optimal for next-gen automotive modules where volume, thermal performance, and qualification rigor are jointly critical.

FAQ
What is the maximum clamping voltage for PTVS20VP1UP-QX under surge conditions?
The maximum clamping voltage (VCL) is 32.4 V at a peak pulse current (IPPM) of 18.5 A, measured per IEC 61643-321 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during transient events.
Is PTVS20VP1UP-QX suitable for bidirectional signal line protection?
No - PTVS20VP1UP-QX is unidirectional and must be used with anode grounded. For bidirectional protection (e.g., USB, RS-485), two devices are required in series opposition or a dedicated bidirectional TVS such as PTVS20VU1UP-QX must be selected.
How does the SOD128 package affect thermal performance in high-density PCB layouts?
The SOD128 package achieves Rth(j-sp) = 12 K/W via direct thermal coupling from the cathode tab to PCB copper, enabling effective heat extraction even with minimal thermal pad area. Its 1 mm height avoids interference with adjacent tall components, and its 3.8 mm × 2.6 mm footprint supports fine-pitch routing in ADAS domain controllers.
Does PTVS20VP1UP-QX require derating at elevated ambient temperatures?
Yes - rated peak pulse power decreases with junction temperature; at 125 °C, PPPM drops to ~70% of 600 W (≈420 W) per Figure 2 in the datasheet. Designers must ensure Tj remains ≤125 °C under worst-case surge repetition and ambient conditions using Rth(j-a) = 200 K/W (FR4, single-sided copper) or Rth(j-sp) = 12 K/W for localized thermal modeling.
