Product details
Overview
PTVS54VP1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at 54 V reverse standoff voltage. It delivers 87.1 A peak pulse current (10/1000 µs), clamps transients to ≤66.3 V, and exhibits ≤0.001 µA reverse leakage at VRWM - deployed in engine control units, battery management systems, and LIN/CAN bus power rails.
For engineers reviewing the PTVS54VP1UP-QX datasheet, PTVS54VP1UP-QX pinout, PTVS54VP1UP-QX application, or PTVS54VP1UP-QX equivalent, key selection criteria include clamping voltage (VCL = 66.3 V max), AEC-Q101 qualification, 1 mm profile for space-constrained PCB layouts, and thermal resistance to solder point (Rth(j-sp) = 12 K/W).
Technical Context
This TVS diode operates as a unidirectional clamp, conducting only during negative transients relative to its anode–cathode polarity. Its breakdown voltage is specified at 60.0–66.3 V (VBR min/typ/max), with clamping occurring at 66.3 V under 87.1 A IPPM per IEC 61643-321 (10/1000 µs waveform).
Thermally, it supports junction temperatures up to 150 °C and achieves Rth(j-a) = 60 K/W on ceramic PCBs. ESD robustness includes 30 kV contact/air discharge (IEC 61000-4-2) and 8 kV HBM - critical for automotive module reliability across temperature extremes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W - sustains 10/1000 µs surge without failure in automotive load-dump scenarios |
| Reverse Standoff Voltage (VRWM) | 54 V - maximum continuous DC voltage before significant leakage; matches 48 V system nominal rails |
| Clamping Voltage (VCL) | 66.3 V max at 87.1 A - limits downstream IC voltage stress during ISO 7637-2 Pulse 5a events |
| Breakdown Voltage (VBR) | 60.0–66.3 V - ensures reliable triggering above normal operating voltage with margin |
| Reverse Leakage (IRM) | ≤0.001 µA at VRWM - negligible standby current impact on low-power automotive sensors |
| ESD Rating | 30 kV contact/air (IEC 61000-4-2) - protects against human-handling and board-level ESD in assembly |
| Package | SOD128 (CFP5) - 3.8 × 2.6 × 1.0 mm surface-mount footprint with cathode-marked bar |
Pinout & Package
SOD128 (CFP5) plastic surface-mounted package: 2-terminal, flat lead, 4 mm pitch, 1 mm height. Cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected circuit's positive rail; conducts surge current to ground when transient exceeds VRWM |
| 2 (A) | Anode | Connected to system ground; completes conduction path during overvoltage event |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood environments (−55 °C to +150 °C ambient, vibration, humidity) |
| Low-profile SOD128 | 1.0 mm max height enables placement beneath connectors or in tight engine-control module layouts |
| High IPPM capability | 87.1 A peak pulse current handles ISO 16750-2 load-dump surges without degradation |
| Ultra-low IRM | 0.001 µA leakage preserves battery life in always-on automotive modules (e.g., telematics, alarm systems) |
| Robust thermal design | Rth(j-sp) = 12 K/W enables direct heat transfer to copper pour, supporting high-reliability operation |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Battery Management System (BMS) |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ54A-Q | 400 W PPPM; 54 V VRWM; SMA package (2.5 mm height) | Lower surge rating; unsuitable for full ISO 7637-2 Pulse 5a compliance | Select only for cost-sensitive non-critical 12 V subsystems with lower surge exposure |
| TPSMD54A | 600 W PPPM; 54 V VRWM; SMD package (2.2 mm height); no AEC-Q101 certification | Lacks automotive qualification; higher thermal resistance (Rth(j-a) = 100 K/W) | Acceptable for industrial power supplies but not for production automotive ECUs requiring AEC validation |
Compared with SMAJ54A-Q and TPSMD54A, PTVS54VP1UP-QX uniquely combines AEC-Q101 qualification, 1 mm profile, and full 600 W/87.1 A surge handling - making it the only choice for space-constrained, safety-critical automotive power rail protection.

FAQ
What is the maximum clamping voltage of PTVS54VP1UP-QX at its rated peak pulse current?
The maximum clamping voltage (VCL) is 66.3 V at 87.1 A peak pulse current (IPPM), measured under IEC 61643-321 10/1000 µs waveform conditions at Tj = 25 °C. This value ensures protected circuits remain below 70 V during worst-case automotive load-dump events.
Is PTVS54VP1UP-QX suitable for bidirectional transient protection?
No - PTVS54VP1UP-QX is a unidirectional TVS diode, configured to clamp only negative transients relative to its anode-to-cathode orientation. For bidirectional protection (e.g., data lines), a symmetric device like PTVS54VU1UP-QX would be required.
How does the SOD128 package affect PCB layout and thermal performance?
The SOD128 (CFP5) package measures 3.8 × 2.6 × 1.0 mm with a cathode-marked bar and enables low-inductance mounting. Its Rth(j-sp) = 12 K/W allows efficient heat transfer to solder pads, but requires ≥1 cm² copper pour on cathode pad per Nexperia's thermal guidelines for sustained 600 W operation.
Does PTVS54VP1UP-QX require derating at elevated ambient temperatures?
Yes - rated peak pulse power decreases with junction temperature. At 125 °C Tj, PPPM drops to ~70 % of 600 W (≈420 W), per Fig. 2 in the datasheet. Designers must verify thermal margins using Rth(j-a) = 60 K/W (ceramic PCB) or 200 K/W (FR4 single-sided) to avoid exceeding 150 °C Tj limit.
