Product details
Overview
PTVS33VP1UTP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature transient overvoltage protection with VRWM = 33 V, VBR(min) = 36.7 V, VCL = 53.3 V at IPPM = 11.3 A, and junction temperature rating up to 185 °C - deployed in industrial power supply rails and high-reliability DC bus protection.
For engineers reviewing the PTVS33VP1UTP,115 datasheet, PTVS33VP1UTP,115 pinout, PTVS33VP1UTP,115 application, or PTVS33VP1UTP,115 equivalent, key selection criteria include clamping voltage under 10/1000 µs surge, thermal resistance to solder point (Rth(j-sp) = 12 K/W), reverse leakage ≤0.001 µA at VRWM, AEC-Q101 qualification status per revision history, and SOD128 footprint compatibility with IPC-7351B reflow land patterns.
Technical Context
This unidirectional TVS diode operates as a clamping device triggered by reverse-biased avalanche breakdown above its 33 V standoff threshold. Its 600 W peak pulse power rating complies with IEC 61643-321 (10/1000 µs waveform), and it maintains stable clamping performance across −55 °C to +185 °C ambient range.
Thermal design is enabled by low Rth(j-sp) = 12 K/W to cathode solder point and robust junction-to-ambient resistance (60 K/W on ceramic PCB). The device exhibits minimal temperature coefficient of breakdown voltage (SZ = 37.5 mV/K) and ultra-low IRM = 0.001 µA at VRWM, ensuring minimal standby power loss in high-impedance protection nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 33 V - maximum continuous reverse operating voltage before significant leakage; sets upper limit for protected line DC bias. |
| VBR (min) | 36.7 V - guaranteed avalanche initiation voltage at 10 mA; ensures reliable turn-on margin above VRWM. |
| VCL @ IPPM | 53.3 V - clamped voltage at 11.3 A peak pulse current; defines worst-case overvoltage seen by downstream circuitry. |
| PPPM | 600 W - peak pulse power handling per IEC 61643-321 10/1000 µs waveform; determines surge energy absorption capability. |
| IRM | 0.001 µA - reverse leakage at VRWM and 25 °C; enables use in ultra-low-power monitoring or high-impedance sensor interfaces. |
| Tj max | 185 °C - maximum junction temperature; supports operation in engine bay, motor drive, or enclosed industrial enclosures without derating. |
| Rth(j-sp) | 12 K/W - thermal resistance from junction to cathode solder point; allows accurate thermal modeling when mounted on standard FR4 with 1 cm² cathode pad. |
Pinout & Package
SOD128 (CFP5) surface-mount plastic package: 2-terminal, flat lead, 3.8 mm × 2.6 mm × 1.0 mm body height, with cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 33 V rail); polarity-sensitive - reverse connection disables clamping function. |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance shunt path during transient events; requires low-inductance grounding. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction rated to 185 °C - eliminates thermal derating in automotive under-hood or industrial motor control environments. |
| AEC-Q101 qualified (per revision v.2) | Qualified per Automotive Electronics Council stress test standard for discrete semiconductors - supports deployment in non-safety-critical automotive subsystems per latest revision history. |
| Ultra-low leakage | IRM ≤ 0.001 µA at VRWM - preserves signal integrity in high-impedance analog sensing and battery-backed circuits. |
| Compact SOD128 footprint | 3.8 mm × 2.6 mm × 1.0 mm profile - enables dense layout in space-constrained power modules and DC-DC converter outputs. |
Applications
| Industrial Power Supply Protection | Motor Drive DC Bus Clamping |
|---|---|
|

IC Role / Device Role / Timing Role: Low-leakage, high-Tj TVS placed adjacent to bridge input terminals to suppress ESD and cable-coupled noise. Use Value: Enables operation at 175 °C ambient with <1 ppm/°C drift impact on bridge balance due to negligible IRM contribution. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ33A | Lower PPPM (400 W), higher VCL (64.5 V), SMC package (higher profile, 2.3 mm height) | Limited to ≤150 °C ambient; not AEC-Q101 qualified per latest revision | Select when cost sensitivity outweighs thermal or automotive compliance requirements. |
| 1.5KE33A | Through-hole DO-201 package, 1500 W rating but larger footprint and higher parasitic inductance | Not suitable for high-frequency surge suppression; incompatible with automated SMT assembly | Choose only for legacy through-hole designs where board real estate and assembly method permit. |
Compared with SMAJ33A and 1.5KE33A, PTVS33VP1UTP,115 delivers superior thermal resilience (185 °C vs. 150 °C), lower clamping voltage (53.3 V vs. 64.5 V), and verified AEC-Q101 compliance for modern SMT-based industrial systems - making it optimal for compact, high-reliability, high-temperature deployments.

FAQ
Is PTVS33VP1UTP,115 qualified for automotive applications?
Yes - per revision v.2 of the datasheet (released 1 December 2025), PTVS33VP1UTP,115 is explicitly listed among the 33 products that retain AEC-Q101 qualification. This applies to non-safety-critical automotive subsystems such as body control modules, infotainment power rails, and HVAC actuators - confirmed in the Revision History table.
What is the maximum allowable surge current for PTVS33VP1UTP,115?
The rated peak pulse current (IPPM) is 11.3 A under IEC 61643-321 10/1000 µs waveform conditions. This value is derived directly from VCL = 53.3 V and PPPM = 600 W using IPPM = PPPM / VCL. It is not a standalone absolute maximum but a defined operational point tied to the standardized test waveform.
How does the 1 mm package height impact PCB layout?
The 1.0 mm maximum height enables placement beneath low-profile heat sinks or in stacked multi-board assemblies. Its SOD128 (CFP5) outline requires 4.4 mm × 4.2 mm reflow solder land pattern per Figure 7, with 2.5 mm × 3.4 mm solder paste stencil apertures - critical for void-free solder joints and thermal reliability in high-power surge events.
Does PTVS33VP1UTP,115 exhibit polarity-sensitive behavior?
Yes - it is a unidirectional TVS diode with cathode (pin 1) and anode (pin 2). Correct orientation is mandatory: cathode connects to the protected line (33 V), anode to ground. Reverse installation prevents avalanche conduction and renders the device ineffective against positive transients on the rail.
