Product details
Overview
PTVS33VP1UP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for clamping transient overvoltages on DC power rails. It features a 33 V reverse standoff voltage (VRWM), 40.6 V maximum clamping voltage (VCL) at 53.3 A peak pulse current (IPPM), and 0.001 µA reverse leakage at VRWM - optimized for industrial power supply protection with low-profile surface-mount integration.
For engineers reviewing the PTVS33VP1UP,115 datasheet, PTVS33VP1UP,115 pinout, PTVS33VP1UP,115 application, or PTVS33VP1UP,115 equivalent, key selection criteria include clamping performance under IEC 61643-321 10/1000 µs waveform, thermal resistance to solder point (12 K/W), AEC-Q101 qualification status per revision history, and compatibility with FR4 PCB layouts using standard CFP5 reflow footprint.
Technical Context
This unidirectional TVS operates as a voltage-clamping device across power rail inputs, triggering conduction when transient voltage exceeds its 33 V standoff threshold. Its silicon avalanche structure delivers precise breakdown at 36.7–40.6 V (VBR min/max) and sustains 600 W peak pulse power per IEC 61643-321 (10/1000 µs).
Thermal design is enabled by low junction-to-solder-point resistance (12 K/W), supporting reliable energy dissipation during repetitive transients. The device exhibits <0.001 µA IRM at VRWM and 11.3 A IPPM at rated clamping voltage - confirming suitability for 24–48 V industrial bus protection where low leakage and fast response are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W per IEC 61643-321 (10/1000 µs); defines maximum transient energy absorption capability |
| Reverse Standoff Voltage (VRWM) | 33 V; maximum continuous DC voltage before significant leakage - sets operating margin for 24 V nominal systems |
| Clamping Voltage (VCL) | 40.6 V max at 53.3 A IPPM; limits downstream voltage stress during surge events |
| Breakdown Voltage (VBR) | 36.7 V min to 40.6 V max at 1 mA; ensures predictable turn-on threshold with tight tolerance |
| Reverse Leakage (IRM) | 0.001 µA at VRWM; negligible standby current for battery-backed or low-power systems |
| Package | SOD128 (CFP5): 3.8 × 2.6 × 1.0 mm, flat lead, surface-mount; enables high-density PCB layout |
| Junction Temperature (Tj) | Rated to 150 °C; supports operation in enclosed industrial enclosures without derating below full PPPM |
Pinout & Package
SOD128 (CFP5) plastic surface-mounted package with 2 terminals, 4 mm pitch, and 1 mm profile. Cathode identified by marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected circuit's positive rail; carries surge current to ground during clamping |
| 2 | Anode (A) | Connected to system ground; completes conduction path during transient overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability (per revision history v.2 for this part number), enabling reuse in industrial transport systems |
| Low-profile SOD128 package | 1.0 mm height enables placement under connectors or in space-constrained power modules |
| High ESD robustness | 30 kV contact discharge (IEC 61000-4-2) and >4 kV HBM rating protect against handling and system-level ESD |
| Thermal efficiency | 12 K/W junction-to-solder-point resistance allows direct thermal coupling to copper pour for sustained pulse handling |
| Low capacitance | Typical 100 pF at 0 V (inferred from Fig. 4 trend for PTVS24VP1UP/PTVS64VP1UP), minimizing signal integrity impact on adjacent traces |
Applications
| Industrial PLC Power Input | Factory Automation I/O Module |
|---|---|
Use Scenario: 24 V DC power input to programmable logic controller exposed to inductive switching noise and lightning-induced surges on factory floor wiring. IC Role / Device Role / Timing Role: Unidirectional TVS placed between +24 V rail and chassis ground to clamp transients before they reach DC-DC converters and microcontrollers. Use Value: 40.6 V clamping voltage ensures downstream 3.3 V/5 V logic remains within absolute maximum ratings during 1 kV/500 A surge events. |
Use Scenario: Digital input/output terminal blocks in modular automation controllers subject to cable discharge events and relay coil flyback. IC Role / Device Role / Timing Role: Rail-to-ground TVS on each channel's power line, leveraging 0.001 µA IRM to avoid loading low-current sensor signals. Use Value: 1 mm SOD128 height permits placement directly at connector entry points without interfering with adjacent signal routing. |
| Telecom Remote Power Feeder | Renewable Energy Charge Controller |
Use Scenario: -48 V DC power feeders in telecom base stations experiencing load dump and hot-swap transients. IC Role / Device Role / Timing Role: Bidirectional protection not required; unidirectional PTVS33VP1UP,115 used with polarity-aware layout to suppress positive-going surges only. Use Value: 600 W PPPM rating handles repeated 10/1000 µs pulses from distributed antenna system (DAS) power cycling. |
Use Scenario: Solar charge controller input stage connecting PV array to battery bank, exposed to lightning-induced common-mode surges. IC Role / Device Role / Timing Role: TVS mounted across PV+ and PV− lines to clamp differential-mode transients before MPPT circuitry. Use Value: 150 °C Tj rating supports operation in unventilated outdoor enclosures up to 85 °C ambient with full power derating. |
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 | DO-214AC package (2.5 mm height), 600 W PPPM, 33 V VRWM, 53.3 V VCL at 11.3 A IPPM | Higher clamping voltage increases risk of downstream IC damage in 3.3 V/5 V systems | Select when board height >1 mm is acceptable and legacy DO-214AC footprint is fixed |
| SMCJ33A | DO-214AB package (2.6 mm height), 1500 W PPPM, 33 V VRWM, 53.3 V VCL at 28.3 A IPPM | Higher power rating requires larger PCB area and thermal relief; over-spec for most 24 V industrial rails | Select only when multi-pulse surge immunity beyond IEC 61000-4-5 Level 4 is mandated |
Compared with SMAJ33A and SMCJ33A, PTVS33VP1UP,115 provides identical VRWM and superior height constraint (1.0 mm vs ≥2.5 mm), tighter VCL (40.6 V vs 53.3 V), and optimized thermal path to PCB - making it preferred for space-limited, high-reliability 24 V industrial power rails.

FAQ
Is PTVS33VP1UP,115 AEC-Q101 qualified?
Yes - per Nexperia's revision history v.2 (2011), PTVS33VP1UP,115 is included in the list of 25 products confirmed as AEC-Q101 qualified. This qualification applies to stress testing per Automotive Electronics Council standards for discrete semiconductors, supporting use in automotive subsystems and industrial transport equipment.
What is the maximum clamping voltage at rated peak pulse current?
The maximum clamping voltage (VCL) for PTVS33VP1UP,115 is 40.6 V at 53.3 A peak pulse current (IPPM), measured per IEC 61643-321 10/1000 µs waveform. This value is specified in Table 8 of the datasheet and defines the upper voltage limit imposed on protected circuitry during surge events.
Can PTVS33VP1UP,115 be used in bidirectional protection configurations?
No - PTVS33VP1UP,115 is a unidirectional TVS diode with cathode/anode polarity. It conducts only for positive transients relative to its anode. For bidirectional protection, two devices must be connected in series opposing configuration, or a dedicated bidirectional TVS (e.g., PTVS33VS1UP) must be selected.
What is the thermal resistance from junction to solder point?
The thermal resistance from junction to solder point (Rth(j-sp)) is 12 K/W, as specified in Table 6. This value assumes soldering of the cathode tab to a standard PCB pad and enables accurate thermal modeling for surge duty cycle analysis in industrial power designs.
