Product details
Overview
PTVS8V5P1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at 8.5 V reverse standoff voltage. It delivers 41.7 A peak pulse current (IPPM), clamps transients to 14.4 V (VCL), and exhibits only 0.01 µA reverse leakage at VRWM - enabling robust ESD and surge immunity in 12 V rail interfaces.
For engineers reviewing the PTVS8V5P1UP-QX datasheet, PTVS8V5P1UP-QX pinout, PTVS8V5P1UP-QX application, or PTVS8V5P1UP-QX equivalent, key selection criteria include its AEC-Q101 qualification, 1 mm profile for space-constrained PCBs, low thermal resistance (Rth(j-sp) = 12 K/W), and IEC 61643-321 (10/1000 µs) compliance for automotive power line protection.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-anode polarity, triggered when reverse voltage exceeds 8.5 V (VRWM). Its breakdown occurs at 9.44–10.40 V (VBR), limiting transient energy via avalanche conduction while maintaining sub-µA leakage below standoff voltage.
Thermal design leverages low junction-to-solder-point resistance (12 K/W) and supports operation up to 150 °C junction temperature. It withstands 30 kV contact/air discharge (IEC 61000-4-2) and 8 kV HBM, meeting stringent automotive EMC and reliability requirements without external biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W - sustains 10/1000 µs surges per IEC 61643-321 without degradation |
| Reverse Standoff Voltage (VRWM) | 8.5 V - maximum continuous reverse voltage before significant leakage begins |
| Clamping Voltage (VCL) | 14.4 V at IPPM = 41.7 A - limits transient voltage seen by downstream ICs during surge events |
| Breakdown Voltage (VBR) | 9.44–10.40 V at IR = 1 mA - defines precise avalanche initiation threshold |
| Reverse Leakage (IRM) | 0.01 µA at VRWM - negligible standby current, critical for low-power automotive modules |
| ESD Rating | 30 kV contact/air (IEC 61000-4-2), 8 kV HBM - protects against human-handling and system-level ESD |
| Package | SOD128 (CFP5) - 3.8 × 2.6 × 1.0 mm surface-mount footprint with 4 mm lead pitch |
Pinout & Package
SOD128 (CFP5) plastic surface-mounted package with 2 terminals, 4 mm pitch, and 1 mm profile. Cathode identified by marking bar on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected circuit's positive rail; absorbs surge current into ground path |
| 2 (A) | Anode | Connected to system ground; completes clamping path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood and infotainment systems per stress test standard |
| Ultra-low profile (1 mm height) | Enables placement beneath connectors or in tight board-to-board spacing without mechanical interference |
| Low Rth(j-sp) = 12 K/W | Minimizes thermal derating in high-density layouts; supports sustained 600 W pulse handling |
| Marking bar identification | Ensures unambiguous cathode orientation during automated optical inspection (AOI) and reflow |
| 100 A non-repetitive forward surge rating | Withstands accidental reverse-polarity connection or load-dump induced forward conduction |
Applications
| Automotive Body Control Module (BCM) | 12 V Automotive Infotainment Power Input |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PTVS8V5P1UP,115 | Same electrical specs but not AEC-Q101 qualified; lacks automotive stress test validation | Restricted to industrial/commercial use; unsuitable for automotive production | Select only for cost-sensitive non-automotive designs where qualification is not required |
| SMAJ8.5A-Q | Higher clamping voltage (14.4 V → 15.0 V), lower IPPM (41.7 A → 38.2 A), SMA package (2.5 mm height) | Less effective clamping margin; larger footprint reduces layout density | Use only if SOD128 footprint is unavailable and 0.6 V higher VCL is acceptable |
Compared with PTVS8V5P1UP-QX, the non-qualified PTVS8V5P1UP offers identical protection performance but no automotive reliability assurance, while SMAJ8.5A-Q trades compactness and tighter clamping for legacy package compatibility and reduced surge margin.

FAQ
What is the maximum operating temperature for PTVS8V5P1UP-QX?
The device supports junction temperatures up to 150 °C and ambient temperatures from –55 °C to +150 °C. Its thermal resistance from junction to solder point is 12 K/W, enabling reliable operation in under-hood automotive locations when mounted per recommended footprint (Fig. 7).
How does the marking bar identify polarity on PTVS8V5P1UP-QX?
The marking bar on the SOD128 package body indicates Pin 1, which is the cathode (K). This aligns with the simplified outline in Table 2 and ensures correct orientation during placement - critical for unidirectional clamping functionality in 12 V rail protection.
Can PTVS8V5P1UP-QX be used for bidirectional protection?
No - it is strictly unidirectional. Its anode must connect to ground and cathode to the protected line. For bidirectional applications, two devices in series opposition or a dedicated bidirectional TVS (e.g., PTVS8V5S1UP-QX) are required.
What is the clamping behavior at lower surge currents, such as 10 A?
At 10 A (10/1000 µs), the clamping voltage is significantly lower than the rated 14.4 V at 41.7 A. While exact values require interpolation from the V-I curve (Fig. 5), typical clamping remains below 12 V - providing tighter protection margins for smaller transients common in data lines and sensor interfaces.
