Product details
Overview
PTVS26VP1UTP-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 = 26 V, VBR(min) = 28.9 V, VCL = 42.1 V at IPPM = 14.3 A (10/1000 µs), and operates up to Tj = 185 °C.
For engineers reviewing the PTVS26VP1UTP-QX datasheet, PTVS26VP1UTP-QX pinout, PTVS26VP1UTP-QX application, or PTVS26VP1UTP-QX equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance data, clamping behavior under surge, and real-world automotive and industrial use context - all critical for robust ESD/surge protection design.
Technical Context
This TVS diode uses a planar silicon junction structure optimized for stable breakdown voltage across temperature (SZ = 0.5 mV/K) and low leakage (IRM = 0.001 µA at VRWM). Its unidirectional configuration enables precise anode-to-cathode clamping during positive transients on DC supply lines.
The device complies with IEC 61643-321 (10/1000 µs waveform) and achieves 30 kV IEC 61000-4-2 contact discharge ESD immunity. Junction-to-solder-point thermal resistance is 12 K/W, enabling effective heat dissipation in compact automotive PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - sustains 10/1000 µs surges without failure under defined thermal conditions |
| Reverse Standoff Voltage | 26 V - maximum continuous DC voltage before significant leakage begins |
| Breakdown Voltage | 28.9 V (min) - voltage at which device enters avalanche conduction at 1 mA |
| Clamping Voltage | 42.1 V at 14.3 A - maximum voltage seen by protected circuit during rated surge |
| Junction Temperature | 185 °C - supports operation in under-hood automotive environments and industrial enclosures |
| ESD Rating | 30 kV contact discharge - exceeds automotive ESD immunity requirements per ISO 10605 |
| Package | SOD128 (CFP5) - 3.8 mm × 2.6 mm × 1.0 mm surface-mount footprint with low-profile height |
Pinout & Package
SOD128 (CFP5) plastic surface-mounted package with 2 terminals, 4 mm pitch, and cathode marked by a bar on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line's higher-potential side (e.g., +12 V rail); carries surge current into ground path |
| 2 | Anode (A) | Connected to system ground or low-impedance return; completes clamping path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress |
| High-temperature stability | Tj ≤ 185 °C ensures consistent clamping performance in engine bay or powertrain control units |
| Low-profile SMD package | 1.0 mm height enables placement beneath shields or in space-constrained modules |
| Low reverse leakage | IRM = 0.001 µA at VRWM minimizes standby power loss in always-on vehicle systems |
| Controlled temperature coefficient | SZ = 0.5 mV/K ensures predictable VBR shift over temperature, simplifying margin analysis |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: Protects 12 V supply rail against load dump (ISO 7637-2 Pulse 5a) and alternator-induced spikes. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery feed and LDO input to clamp transients before regulation. Use Value: Limits voltage to ≤42.1 V during 14.3 A surges, preventing damage to downstream PMICs and microcontrollers. |
Use Scenario: Shields LIN bus interface power and signal lines from ESD and cable discharge events. IC Role / Device Role / Timing Role: Mounted directly at connector entry point to divert fast transients (<1 ns rise time) to chassis ground. Use Value: Withstands 30 kV contact ESD and maintains <0.001 µA leakage, preserving sleep-mode current budgets. |
| Industrial 24 V PLC I/O Module | EV Onboard Charger (OBC) Auxiliary Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ26A-Q | Higher VCL = 42.8 V at 14.3 A; larger DO-214AB package (7.11 mm × 6.22 mm) | Less suitable for ultra-thin modules due to 2.6 mm height; lower thermal resistance (Rth(j-a) ≈ 35 K/W) | Preferred where board space allows and higher surge margin is needed beyond 600 W |
| TPSMA6L26A | VCL = 42.5 V at 14.3 A; same SOD128 footprint but only rated to Tj = 150 °C | Not AEC-Q101 qualified; lacks high-temp stability above 150 °C required for under-hood use | Acceptable for non-automotive industrial 24 V systems with ambient <105 °C |
Compared with SMCJ26A-Q and TPSMA6L26A, PTVS26VP1UTP-QX uniquely combines AEC-Q101 qualification, 185 °C junction rating, and 1.0 mm profile - making it the only option for space-constrained, high-temperature automotive power protection where thermal derating and reliability are non-negotiable.

FAQ
What is the maximum clamping voltage of PTVS26VP1UTP-QX at its rated peak pulse current?
The clamping voltage (VCL) is 42.1 V at IPPM = 14.3 A under 10/1000 µs waveform conditions, measured at Tj = 25 °C. This value is guaranteed per Nexperia's Product Data Sheet Rev. 20251117, Table 8, and defines the upper voltage limit imposed on protected circuits during surge events.
Is PTVS26VP1UTP-QX suitable for bidirectional transient protection?
No - PTVS26VP1UTP-QX is a unidirectional TVS diode, intended for clamping positive transients on DC lines referenced to ground. It does not suppress negative-going surges; a bidirectional variant (e.g., PTVS26VS1UTP-QX) would be required for AC or dual-polarity protection.
How does the 185 °C junction rating impact PCB layout decisions?
The 185 °C rating allows operation in high-ambient zones (e.g., near power converters), but thermal design must still ensure Rth(j-sp) = 12 K/W is achieved via adequate copper area on the cathode pad (≥1 cm² tin-plated FR4 recommended per Table 6). No external heatsink is needed, but solder joint integrity must be validated for thermal cycling.
Does PTVS26VP1UTP-QX require derating of peak pulse power at elevated temperatures?
Yes - Figure 2 shows PPPM decreases to ~80% of 600 W at Tj = 150 °C and ~60% at Tj = 175 °C. Designers must apply junction temperature-based derating using the published relative curve to maintain safe operation during sustained high-temp operation or repeated surge events.
