Product details
Overview
PTVS11VP1UP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) diode in SOD128 (CFP5) package, designed for high-energy transient overvoltage protection on DC power rails and signal lines. It features a 11 V reverse standoff voltage (VRWM), 13.5 V maximum clamping voltage (VCL) at 33.0 A peak pulse current (IPPM), and 0.005 µA reverse leakage at VRWM - optimized for industrial and embedded power supply protection with 1 mm profile.
For engineers reviewing the PTVS11VP1UP,115 datasheet, PTVS11VP1UP,115 pinout, PTVS11VP1UP,115 application, or PTVS11VP1UP,115 equivalent, this device serves as a compact, AEC-Q101-qualified (per revision history) unidirectional TVS for robust ESD and surge immunity in space-constrained 12 V system rails, including DC-DC input stages and I/O interface protection where low clamping and minimal capacitance (<100 pF) are critical.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (IRM ≤ 0.005 µA at 11 V), then avalanches sharply at VBR = 12.2–13.5 V to clamp transients to ≤18.2 V while diverting up to 33.0 A (10/1000 µs waveform). Its junction-to-solder-point thermal resistance is 12 K/W, enabling reliable power dissipation in compact PCB layouts.
The device complies with IEC 61643-321 for 600 W peak pulse power rating and achieves 30 kV IEC 61000-4-2 contact ESD immunity. Its SOD128 footprint supports automated reflow soldering with defined land patterns (4.4 mm × 2.1 mm cathode/anode pads), and the marking bar identifies the cathode terminal per JEDEC-standard polarity convention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W - sustains 10/1000 µs surges without failure, suitable for IEC 61000-4-5 Level 3/4 protection. |
| Reverse Standoff Voltage (VRWM) | 11 V - maximum continuous DC operating voltage before significant leakage; matches nominal 12 V rail systems. |
| Clamping Voltage (VCL) | 18.2 V max at IPPM = 33.0 A - limits transient voltage to safe levels for downstream 20 V-rated ICs. |
| Breakdown Voltage (VBR) | 12.2–13.5 V at IR = 1 mA - defines precise avalanche onset threshold for predictable clamping behavior. |
| Reverse Leakage (IRM) | 0.005 µA at VRWM - negligible standby current, avoiding power loss in always-on circuits. |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity requirements. |
| Package | SOD128 (CFP5) - 3.8 mm × 2.6 mm × 1.0 mm surface-mount outline with 4 mm lead pitch and cathode-marked polarity. |
Pinout & Package
SOD128 (CFP5) plastic surface-mount package: 2-terminal, flat-lead, 1 mm height, cathode marked by bar. Optimized for high-density PCB layout and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., +12 V rail); avalanche conduction occurs from anode to cathode during overvoltage. |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance shunt path during transient events to clamp voltage rise. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 1.0 mm height enables use in ultra-thin consumer and automotive modules where Z-axis space is constrained. |
| AEC-Q101 qualified | Qualified per revision history v.3 (2025) for automotive-grade reliability - validated for temperature cycling, HBM ESD, and surge endurance. |
| Low clamping ratio | VCL/VRWM = 1.65 - delivers tight voltage limiting relative to standoff, improving margin for downstream 20 V logic and power ICs. |
| Minimal parasitic capacitance | <100 pF at 0 V (typical) - preserves signal integrity on high-speed data lines (e.g., CAN, LIN) when used for bus protection. |
| High surge current capability | 33.0 A peak pulse (10/1000 µs) - handles repetitive load dump and ISO 7637-2 Pulse 5a transients in 12 V vehicle systems. |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |

Use Scenario: Protecting 12 V DC input stage of programmable logic controllers (PLCs) against lightning-induced surges and inductive switching spikes. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between VIN and GND, clamping transients within 1 ns response time to prevent damage to upstream DC-DC controllers. Use Value: Enables compliance with IEC 61000-4-5 Level 4 (4 kV line-to-earth) without bulkier MOV-based solutions, reducing board area by >60%. |
Use Scenario: Safeguarding LIN bus transceivers and microcontroller I/O pins in door module ECUs exposed to battery disconnect/load dump events. IC Role / Device Role / Timing Role: Low-capacitance TVS mounted directly at connector entry point, suppressing fast-rising transients before they propagate into sensitive analog/digital circuitry. Use Value: Maintains <100 pF capacitance to avoid LIN signal distortion while delivering 30 kV ESD immunity and 33 A surge handling per ISO 16750-2. |
| Medical Equipment DC Rail Protection | Smart Building Sensor Node Power Input |
|
Use Scenario: Securing 12 V auxiliary power input of portable ultrasound units against ESD and accidental AC mains coupling during field service. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power entry, coordinated with upstream fuse and downstream LDO to form tiered protection architecture. Use Value: Achieves Class B ESD immunity (IEC 61326-1) with single-device solution, eliminating need for RC filters that degrade voltage regulation. |
Use Scenario: Protecting PoE-powered environmental sensors (temperature/humidity) connected to building management systems via 24 V DC distribution. IC Role / Device Role / Timing Role: Standoff-rated TVS on DC input rail, absorbing induced surges from nearby HVAC motor switching and long cable runs. Use Value: Provides 600 W peak power handling in 3.8 mm × 2.6 mm footprint - 4× smaller than legacy DO-214AC packages, enabling miniaturized node design. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | DO-214AC package (4.5 mm × 2.7 mm × 2.3 mm); 11.1 V VRWM; 18.2 V VCL at 32.9 A; 400 W PPPM. | Larger footprint and 2.3 mm height limit use in ultra-thin designs; lower peak power reduces margin for repeated surges. | Select when legacy DO-214AC footprint compatibility is required and board height >2.3 mm is acceptable. |
| TPSMD11CA | Bi-directional configuration; 11 V VRWM; 19.5 V VCL at 30.8 A; 600 W PPPM; same SOD128 package. | Clamps both positive and negative transients - unnecessary for DC-only rails, adding ~15% capacitance vs. unidirectional variant. | Choose only if bidirectional protection (e.g., AC-coupled signal lines) is needed; otherwise PTVS11VP1UP offers lower leakage and capacitance. |
Compared with SMAJ11A, PTVS11VP1UP,115 delivers identical clamping performance in 40% less board area and 57% lower profile; versus TPSMD11CA, it provides 30% lower IRM and 12% lower typical capacitance - critical for low-power always-on sensor nodes.

FAQ
What is the maximum operating temperature for PTVS11VP1UP,115?
The junction temperature (Tj) must not exceed 150 °C under steady-state or transient conditions. The device is rated for ambient temperatures from –55 °C to +150 °C, with thermal resistance from junction to solder point at 12 K/W - enabling reliable operation in engine bay or industrial enclosure environments when properly mounted on ≥1 cm² copper pour.
Does PTVS11VP1UP,115 meet automotive qualification standards?
Yes - per revision history v.3 (December 2025), PTVS11VP1UP,115 is explicitly listed among the 25 types upgraded to AEC-Q101 qualification. This includes stress testing for temperature cycling, humidity, ESD (HBM >4 kV, IEC contact 30 kV), and surge endurance per Automotive Electronics Council requirements.
How does the clamping voltage change with pulse duration?
VCL remains stable across standard 10/1000 µs waveforms but decreases slightly for shorter pulses (e.g., 10/100 µs) due to thermal inertia - Figure 3 shows PPPM drops to ~400 W at 10 µs. For precise values, consult Table 8: at IPPM = 33.0 A (10/1000 µs), VCL is 18.2 V max; at 10/100 µs, VCL is typically ~16.5 V.
Can PTVS11VP1UP,115 be used in parallel for higher surge current handling?
No - unidirectional TVS diodes exhibit manufacturing spread in VBR (±5% typical), causing current imbalance. Parallel connection risks thermal runaway in the lower-VBR unit. For >33 A capability, select a higher-rated single device (e.g., PTVS12VP1UP,115 at 30.2 A) or implement external current-sharing resistors - not recommended for production designs.
