Product details
Overview
PTVS26VP1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at 26 V reverse standoff voltage. It delivers 42.1 A peak pulse current (10/1000 µs), clamps transients to ≤31.9 V at rated current, and exhibits ≤0.1 µA reverse leakage at VRWM - deployed in power supply rails of engine control units and ADAS sensor interfaces.
For engineers reviewing the PTVS26VP1UP-QX datasheet, PTVS26VP1UP-QX pinout, PTVS26VP1UP-QX application, or PTVS26VP1UP-QX equivalent, key selection criteria include its AEC-Q101 qualification, 1 mm profile for space-constrained PCB layouts, low clamping ratio (VCL/VRWM ≈ 1.23), and thermal resistance of 12 K/W to solder point - critical for sustained surge handling in 12 V/24 V automotive systems.
Technical Context
This TVS diode operates as a unidirectional clamping device: under normal bias, it blocks up to 26 V reverse voltage with <0.1 µA leakage; during transient events exceeding VBR (28.9–31.9 V), it avalanches to divert surge current away from protected ICs. Its junction-to-solder-point thermal resistance (12 K/W) enables effective heat dissipation into copper pads without heatsinks.
The device complies with IEC 61643-321 (10/1000 µs waveform) and achieves 30 kV ESD immunity per IEC 61000-4-2 (contact/air), making it suitable for CAN/LIN bus line protection and microcontroller I/O rail hardening where fast response (<1 ns) and low capacitance (<100 pF at 0 V) are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - sustains 10/1000 µs surges up to 42.1 A without failure |
| Reverse Standoff Voltage | 26 V - maximum continuous DC operating voltage before leakage exceeds 0.1 µA |

Applications
| Engine Control Unit (ECU) Power Rail | CAN Transceiver Protection |
|---|---|
|
Use Scenario: Protecting 24 V supply input of diesel ECU against load dump transients (ISO 7637-2 Pulse 5a). IC Role / Device Role / Timing Role: Unidirectional TVS clamping device placed between battery feed and LDO input. Use Value: Limits voltage to ≤31.9 V during 100 V/100 ms surges, preventing LDO destruction and ensuring firmware continuity. |
Use Scenario: Safeguarding high-speed CAN FD transceiver (e.g., TJA1044) I/O lines from ESD and coupled noise. IC Role / Device Role / Timing Role: Low-capacitance TVS on CANH/CANL differential pair, grounded via short traces. Use Value: Clamps ESD spikes to <32 V while adding <50 pF capacitance - preserves signal integrity up to 5 Mbps. |
| ADAS Camera Module Interface | Body Control Module (BCM) Sensor Inputs |
|
Use Scenario: Shielding MIPI CSI-2 interface lines of 8 MP automotive camera from cable discharge events. IC Role / Device Role / Timing Role: Discrete TVS on each data lane, placed adjacent to connector with minimal stub length. Use Value: Responds in <1 ns to 8 kV HBM discharges, limiting voltage excursion to <32 V without distorting 1.5 Gbps video signals. |
Use Scenario: Protecting analog inputs (e.g., temperature, humidity sensors) in BCM against battery reversal and jump-start surges. IC Role / Device Role / Timing Role: Series TVS on sensor supply line, combined with RC filter for low-frequency filtering. Use Value: Blocks reverse polarity up to −26 V and clamps positive transients to 31.9 V - avoids op-amp latch-up and ADC saturation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ26A-Q | 400 W PPPM; higher clamping voltage (42.1 V); SMA package (2.5 mm height) | Lower surge margin; unsuitable for space-constrained AEC-Q101 designs requiring 600 W | Select only if board height >2.5 mm and peak surge current <30 A is sufficient |
| TPSMF26A | 600 W PPPM; same VRWM; SOD-123FL package (1.1 mm height); 35.5 V clamping | Higher clamping ratio (1.37× vs. 1.23×); slightly larger footprint (3.7 × 1.7 mm) | Prefer when lower VCL is not critical and existing SOD-123FL layout reuse is prioritized |
Compared with SMAJ26A-Q and TPSMF26A, PTVS26VP1UP-QX offers the lowest clamping voltage (31.9 V) and smallest height (1.0 mm) among AEC-Q101-qualified 26 V TVS diodes - enabling tighter voltage margins and denser placement in modern ADAS and powertrain ECUs.

FAQ
What is the maximum clamping voltage of PTVS26VP1UP-QX at its rated peak pulse current?
The maximum clamping voltage (VCL) is 31.9 V at 42.1 A peak pulse current (IPPM), measured under IEC 61643-321 10/1000 µs waveform conditions. This value ensures downstream components see no more than 31.9 V during worst-case surge events, preserving functionality of 3.3 V or 5 V logic supplies downstream of the TVS.
Is PTVS26VP1UP-QX suitable for bidirectional transient protection?
No - PTVS26VP1UP-QX is a unidirectional TVS diode, optimized for clamping positive transients on DC-biased lines. It conducts only when anode-to-cathode voltage exceeds breakdown; reverse polarity events are blocked but not clamped. For bidirectional protection (e.g., AC lines or data buses), a dedicated bidirectional variant like PTVS26VS1UP-QX must be used.
How does the SOD128 package enhance thermal performance compared to SMA or SMC packages?
The SOD128 (CFP5) package features a low-profile, flat-lead structure with direct thermal path from die to cathode pad, achieving 12 K/W junction-to-solder-point resistance - significantly lower than SMA (≈40 K/W) or SMC (≈25 K/W). This allows efficient heat transfer into PCB copper, sustaining repeated 600 W surges without thermal runaway in compact automotive modules.
What is the significance of the 'Q' suffix in PTVS26VP1UP-QX?
The 'Q' suffix indicates AEC-Q101 qualification - confirming the device has passed stress tests including high-temperature operating life, temperature cycling, and ESD per Automotive Electronics Council standards. This certification validates suitability for automotive applications such as powertrain, chassis, and ADAS systems where reliability under harsh environmental conditions is mandatory.
