Product details
Overview
PTVS26VP1UP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-energy transient suppression on DC power rails. It features a 26 V reverse standoff voltage (VRWM), 30.4 V typical breakdown voltage (VBR), 42.1 A peak pulse current (IPPM), and clamps transients to ≤42.1 V at rated pulse, targeting protection of automotive and industrial 24 V systems.
For engineers reviewing the PTVS26VP1UP,115 datasheet, PTVS26VP1UP,115 pinout, PTVS26VP1UP,115 application, or PTVS26VP1UP,115 equivalent, key selection criteria include VRWM tolerance, clamping voltage under 42.1 A IPPM, thermal resistance to solder point (12 K/W), and AEC-Q101 qualification status per revision history.
Technical Context
This unidirectional TVS diode operates as a shunt protector: it remains high-impedance below 26 V VRWM, then avalanches sharply at ~30.4 V VBR to clamp surges. Its IEC 61643-321-compliant 10/1000 μs waveform response ensures robustness against lightning-induced and inductive-switching transients.
Thermal design is enabled by low Rth(j-sp) = 12 K/W to cathode solder point and 1 mm profile, supporting high-density PCB layouts. The device sustains 100 A non-repetitive forward surge (IFSM) and exhibits <0.1 µA IRM at VRWM - critical for low-power standby circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W - withstands 10/1000 μs surges up to this energy level without failure |
| Reverse Standoff Voltage (VRWM) | 26 V - maximum continuous DC voltage before leakage exceeds 0.1 µA |
| Breakdown Voltage (VBR) | 30.4 V typ at 1 mA - precise avalanche initiation threshold for predictable clamping onset |
| Clamping Voltage (VCL) | 42.1 V max at 42.1 A IPPM - limits downstream voltage stress during worst-case surge |
| Peak Pulse Current (IPPM) | 42.1 A - maximum single-pulse surge current the device safely diverts |
| Junction-to-Solder-Point Rth | 12 K/W - enables efficient heat transfer to PCB copper, sustaining repeated pulses |
| ESD Rating (HBM) | >4 kV - protects against handling-induced electrostatic discharge during assembly |
Pinout & Package
PTVS26VP1UP,115 uses the SOD128 (CFP5) surface-mount plastic package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat lead profile optimized for automated placement and reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Marked side) | Cathode (K) | Connected to protected line (e.g., 24 V rail); avalanche conduction occurs from cathode to anode during overvoltage |
| 2 | Anode (A) | Connected to ground reference; forms low-impedance path to GND when clamping |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability (per revision v.2 qualification list including PTVS26VP1UP) |
| Low-profile SOD128 package | 1.0 mm height enables use in space-constrained modules and stacked PCB assemblies |
| Ultra-low leakage current | IRM ≤ 0.1 µA at 26 V ensures minimal standby power loss in always-on systems |
| High ESD immunity | 30 kV contact discharge (IEC 61000-4-2) and >4 kV HBM protect during manufacturing and field operation |
| Thermally optimized cathode tab | Rth(j-sp) = 12 K/W allows direct heat sinking to large copper pour, improving pulse endurance |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: Protects 24 V supply input of BCM microcontroller and CAN transceivers against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between 24 V rail and chassis ground, clamping transients within 1 ns response time. Use Value: Limits voltage to ≤42.1 V during 42.1 A surges, preventing latch-up or damage to 3.3 V/5 V logic supplies downstream. |
Use Scenario: Shields 24 V digital input channels of programmable logic controllers from field-wiring induced transients. IC Role / Device Role / Timing Role: Front-end transient suppressor on each optocoupler input, operating in parallel with series current-limiting resistor. Use Value: Maintains signal integrity by suppressing >1 kV spikes while adding <0.5 pF capacitance - negligible at 10 kHz input rates. |
| Telecom Power Supply Rail | Medical Equipment DC Power Entry |
Use Scenario: Guards primary 24 V DC-DC converter input in outdoor telecom cabinets exposed to lightning-induced surges. IC Role / Device Role / Timing Role: First-line defense on main power entry, coordinated with upstream fuse and downstream LC filter. Use Value: Absorbs 600 W peak energy per IEC 61643-321, enabling compliance with EN 61000-4-5 Level 4 (4 kV line-earth). |
Use Scenario: Secures 24 V auxiliary power input of diagnostic imaging equipment against ESD and switching noise from adjacent motors. IC Role / Device Role / Timing Role: Low-leakage TVS on isolated power entry, selected for <0.1 µA IRM to avoid compromising patient-isolation leakage budgets. Use Value: Provides 30 kV ESD immunity without degrading safety-critical creepage/clearance requirements due to compact 3.8 mm × 2.6 mm footprint. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ26A | DO-214AC package; 400 W PPPM; 43.5 V VCL @ 38.8 A; Rth(j-a) = 60 K/W | Larger footprint (4.5 mm × 2.7 mm); higher thermal resistance reduces pulse repetition capability | Choose if legacy DO-214AC layout exists and 400 W rating suffices for lower-energy environments |
| TPSMD26 | SMD package; 600 W PPPM; 42.5 V VCL @ 42.1 A; not AEC-Q101 qualified | Same clamping performance but lacks automotive qualification documentation per revision history | Prefer for cost-sensitive industrial designs where AEC-Q101 is not mandated |
Compared with SMAJ26A and TPSMD26, PTVS26VP1UP,115 delivers identical 600 W surge handling and tighter 42.1 V clamping in a 30% smaller footprint with verified AEC-Q101 status - making it optimal for next-gen automotive and space-constrained industrial modules requiring repeatable surge resilience.

FAQ
Is PTVS26VP1UP,115 qualified to AEC-Q101?
Yes - per the revision history in the December 2025 datasheet, PTVS26VP1UP is explicitly included in the list of 25 devices upgraded to standard AEC-Q101 qualification in version v.2. This confirms its suitability for automotive applications including body electronics and powertrain subsystems.
What is the maximum clamping voltage at rated surge current?
The maximum clamping voltage (VCL) for PTVS26VP1UP,115 is 42.1 V at 42.1 A peak pulse current (IPPM), measured under IEC 61643-321 10/1000 μs waveform conditions. This value is guaranteed across temperature and ensures downstream ICs see no more than 42.1 V during full-rated surge events.
Can PTVS26VP1UP,115 be used in bidirectional configurations?
No - PTVS26VP1UP,115 is a unidirectional TVS diode with cathode/anode polarity. It conducts only during positive transients on the cathode relative to anode. For bidirectional protection, two devices must be connected in series opposition or a dedicated bidirectional part like PTVS26VS1UP should be selected.
How does its thermal resistance compare to standard SMB packages?
PTVS26VP1UP,115 achieves Rth(j-sp) = 12 K/W to the cathode solder point - significantly lower than typical SMB-package TVS diodes (~25–35 K/W). This is enabled by its wide cathode tab and optimized SOD128 footprint, allowing higher pulse repetition rates without junction overheating.
