Product details
Overview
PTVS54VP1UTP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature transient overvoltage protection in automotive power rails. It features VRWM = 54 V, VBR(min) = 60.0 V at IR = 1 mA, VCL = 87.1 V at IPPM = 6.9 A (10/1000 µs), and operates up to Tj = 185 °C.
For engineers reviewing the PTVS54VP1UTP-QX datasheet, PTVS54VP1UTP-QX pinout, PTVS54VP1UTP-QX application, or PTVS54VP1UTP-QX equivalent, this device is selected for robust ESD and surge immunity in 12 V/24 V/48 V automotive subsystems where thermal stability and AEC-Q101 compliance are mandatory.
Technical Context
This unidirectional TVS diode clamps transients above its reverse standoff voltage using avalanche breakdown, with precise VBR tolerance (±5 % typical) and low temperature coefficient (SZ = 0.5 mV/K). Its junction-to-solder-point thermal resistance is 12 K/W, enabling reliable operation under sustained high ambient conditions.
The device complies with IEC 61643-321 (10/1000 µs waveform) and achieves 30 kV contact/air discharge per IEC 61000-4-2. Its low IRM ≤ 0.001 µA at VRWM ensures minimal leakage in always-on power monitoring circuits.

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 | Lower PPPM (400 W), higher VCL (93.6 V at 5.4 A), same SOD-123 package | Limited to lower-energy transients; less suitable for load dump in 24 V systems | Select when cost sensitivity outweighs peak surge requirement and board space permits larger footprint |
| SMCJ54A-Q | Same PPPM (600 W), but larger SMC (DO-214AB) package (7.11 × 6.22 × 2.34 mm) | Higher thermal mass improves long-duration surge handling but increases PCB area by 3× | Prefer when system-level thermal design requires greater junction-to-ambient dissipation margin |
Compared with SMAJ54A-Q and SMCJ54A-Q, PTVS54VP1UTP-QX delivers identical 600 W surge capability in a 3.8 × 2.6 mm footprint with 1 mm height-enabling denser automotive PCB layouts while maintaining AEC-Q101 qualification and 185 °C junction rating.

FAQ
What is the maximum clamping voltage of PTVS54VP1UTP-QX at rated peak pulse current?
The clamping voltage VCL is 87.1 V at IPPM = 6.9 A under 10/1000 µs waveform conditions, measured at Tj = 25 °C. This value remains within ±5 % across operating temperature range –55 °C to +150 °C, ensuring consistent overvoltage limiting in automotive environments.
Does PTVS54VP1UTP-QX support bidirectional transient suppression?
No, PTVS54VP1UTP-QX is a unidirectional TVS diode. It conducts only when the cathode is positive relative to the anode, making it suitable for DC power rail protection. For AC or data-line applications requiring symmetrical clamping, a bidirectional variant such as PTVS54VB1UTP-QX would be required.
How does the thermal resistance of PTVS54VP1UTP-QX impact PCB layout?
With Rth(j-sp) = 12 K/W to the cathode solder point, optimal PCB layout requires a minimum 1 cm² copper pour connected to Pin 1 (cathode) to achieve rated 600 W performance. Use of internal ground planes and thermal vias further reduces effective junction temperature rise during repeated surge events.
Is PTVS54VP1UTP-QX compatible with lead-free reflow soldering profiles?
Yes, the CFP5 (SOD128) package is qualified for standard IPC/JEDEC J-STD-020 lead-free reflow profiles, including peak temperatures up to 260 °C. The recommended solder land pattern matches Figure 7 in the datasheet, with 2.5 mm × 3.4 mm occupied area and dual 1.9 mm × 2.1 mm solder pads.
