Product details
Overview
PTVS64VP1UTP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature overvoltage protection in automotive power rails. It features VRWM = 64 V, VBR(min) = 71.1 V at IR = 1 mA, clamping voltage VCL = 103.0 V at IPPM = 5.8 A (10/1000 µs), junction temperature rating up to 185 °C, and AEC-Q101 qualification.
For engineers reviewing the PTVS64VP1UTP-QX datasheet, PTVS64VP1UTP-QX pinout, PTVS64VP1UTP-QX application, or PTVS64VP1UTP-QX equivalent, this device is selected for robust ESD and surge protection in 12 V/24 V/48 V automotive subsystems where thermal stability and low-profile mounting are critical.
Technical Context
This unidirectional TVS diode operates as a clamping device: under normal bias it presents high impedance (>1 GΩ at VRWM), but triggers into low-impedance conduction when reverse voltage exceeds VBR, limiting transient energy via controlled avalanche breakdown. Its 10/1000 µs IEC 61643-321 waveform compliance ensures standardized surge immunity testing.
The SOD128 package enables surface-mount integration with minimal board footprint (3.8 mm × 2.6 mm × 1.0 mm) and low thermal resistance (Rth(j-sp) = 12 K/W to solder point), supporting reliable operation in ambient temperatures from −55 °C to +185 °C and junction temperatures up to 185 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A-Q | Lower PPPM (400 W), higher VCL (104 V), same VRWM (64 V), SMA package (higher profile, lower thermal performance) | Limited to under-dash modules with lower surge exposure; not qualified to AEC-Q101 | Select only if cost sensitivity outweighs thermal and qualification requirements |
| TPSMD64AH | Higher PPPM (1500 W), larger DO-214AB package, VCL = 103 V, AEC-Q101 qualified | Better suited for high-energy load dump in commercial vehicle systems; requires more PCB area | Choose when surge energy exceeds 600 W or board layout allows larger footprint |
Compared with SMAJ64A-Q and TPSMD64AH, PTVS64VP1UTP-QX uniquely balances AEC-Q101 compliance, 600 W surge capability, and ultra-low 1 mm profile-making it optimal for space-constrained, high-temperature automotive electronics where thermal management and qualification are non-negotiable.

FAQ
What is the maximum clamping voltage of PTVS64VP1UTP-QX at its rated peak pulse current?
The clamping voltage VCL is 103.0 V at IPPM = 5.8 A under 10/1000 µs waveform conditions per IEC 61643-321. This value is measured at Tj = 25 °C and represents the upper voltage limit imposed on the protected circuit during a full-rated surge event.
Does PTVS64VP1UTP-QX support bidirectional transient suppression?
No. PTVS64VP1UTP-QX is a unidirectional TVS diode, configured for reverse-biased operation only. It protects against positive transients on the cathode side relative to anode (ground). For bidirectional protection, two devices in series opposition or a dedicated bidirectional part such as PTVS64VB1UTP-QX would be required.
How does the 185 °C junction temperature rating impact PCB layout decisions?
The 185 °C Tj rating permits operation in high-ambient zones (e.g., near engines or power converters), but effective thermal design remains essential: use ≥1 cm² copper pour on cathode pad (per datasheet Fig. 7), avoid thermal isolation, and ensure reflow profile meets Nexperia's CFP5 specifications to maintain solder joint integrity and long-term reliability.
Is the marking code 'D7' confirmed for PTVS64VP1UTP-QX on the device body?
Yes. Per Table 4 of the datasheet, PTVS64VP1UTP-QX is marked with 'D7' on the top surface of the SOD128 package. The marking bar adjacent to pin 1 identifies the cathode, and 'D7' is laser-etched or molded for automated optical inspection and traceability.
