Product details
Overview
PTVS16VP1UTP,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 = 16 V, VBR(min) = 17.8 V, VCL = 26.0 V at IPPM = 23.1 A (10/1000 μs), and junction temperature rating up to 185 °C - deployed in industrial power management and high-reliability DC supply rails.
For engineers reviewing the PTVS16VP1UTP,115 datasheet, PTVS16VP1UTP,115 pinout, PTVS16VP1UTP,115 application, or PTVS16VP1UTP,115 equivalent, this device serves as a high-power, high-temperature-rated unidirectional TVS diode requiring precise clamping voltage control, low leakage (<0.001 µA), and thermal robustness in constrained PCB layouts.
Technical Context
This TVS operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds VRWM (16 V), entering breakdown at VBR (17.8–19.7 V) to clamp transients with a maximum clamping voltage of 26.0 V at 23.1 A peak pulse current. Its IEC 61643-321-compliant 10/1000 μs waveform response ensures standardized surge immunity validation.
Thermal design is enabled by Rth(j-a) = 200 K/W (FR4, single-sided copper) and Rth(j-sp) = 12 K/W (cathode solder point), supporting operation up to Tamb = 185 °C and Tj = 185 °C. The device exhibits a positive temperature coefficient (SZ = +15.9 mV/K), meaning clamping voltage increases predictably with junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 16 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin in protected line. |
| VBR (min) | 17.8 V - minimum breakdown voltage at 10 mA; ensures reliable turn-on above VRWM with 11% margin. |
| VCL @ IPPM | 26.0 V at 23.1 A - clamping voltage under 10/1000 μs surge; limits downstream IC stress during ESD/EFT events. |
| PPPM | 600 W - rated peak pulse power per IEC 61643-321; enables robust protection against 8/20 μs or 10/1000 μs surges. |
| IRM | 0.001 µA @ VRWM - ultra-low reverse leakage; minimizes standby power loss and avoids false triggering in high-impedance circuits. |
| Tj max | 185 °C - maximum junction temperature; supports operation in under-hood automotive zones or sealed industrial enclosures. |
| Package | SOD128 (CFP5) - 3.8 mm × 2.6 mm × 1.0 mm surface-mount outline with cathode marking bar; optimized for automated placement and thermal relief. |
Pinout & Package
SOD128 (CFP5) plastic surface-mounted package: 2-terminal, flat lead, 4 mm pitch, body dimensions 3.8 mm × 2.6 mm × 1.0 mm; cathode identified by molded marking bar on terminal 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line's higher-potential side (e.g., VBUS); carries full surge current during clamping; requires thermal pad connection for Rth(j-sp) = 12 K/W. |
| 2 | Anode (A) | Connected to ground or lower-potential reference; completes conduction path during transient; must be low-inductance ground plane for effective clamping. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature stability | Rated for continuous operation at Tj ≤ 185 °C and Tamb ≤ 185 °C - eliminates derating in thermally aggressive environments like motor drives or LED drivers. |
| Low-profile SMD package | 1.0 mm max height - enables use in space-constrained applications such as portable medical devices or stacked PCB assemblies. |
| AEC-Q101 qualified | Qualified per Automotive Electronics Council standard for discrete semiconductors - validated for reliability in automotive subsystems despite revision history note on qualification status. |
| Ultra-low leakage | IRM ≤ 0.001 µA at VRWM - prevents signal integrity degradation and battery drain in always-on sensor nodes or backup power circuits. |
| Controlled clamping slope | SZ = +15.9 mV/K temperature coefficient - enables predictable VCL rise with temperature, simplifying worst-case margining in thermal-aware designs. |
Applications
| Industrial Power Supply Protection | DC Motor Drive Input Stage |
|---|---|
|
Use Scenario: Protecting 24 V DC input rails in programmable logic controllers (PLCs) against load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VIN and GND, conducting only during negative-going surges on the supply line. Use Value: Clamps 10/1000 μs surges to ≤26.0 V while sustaining 600 W peak power - prevents damage to upstream DC-DC converters and microcontrollers. |
Use Scenario: Safeguarding H-bridge gate driver ICs from flyback voltage spikes generated by brushed DC motors during PWM commutation. IC Role / Device Role / Timing Role: Mounted across motor supply rail (VMOT–GND) to absorb inductive kick energy within <1 μs response time. Use Value: Limits transient overshoot to 26.0 V at 23.1 A, enabling use of 30 V-rated gate drivers without overvoltage shutdown or latch-up. |
| High-Temperature Sensor Interface | Telecom Power Shelf Protection |
|
Use Scenario: Shielding analog front-end circuitry in oil & gas downhole sensors operating continuously at 175 °C ambient. IC Role / Device Role / Timing Role: Reverse-biased TVS on excitation line (e.g., 12 V sensor bias), absorbing ESD and cable discharge events. Use Value: Maintains IRM < 0.001 µA and functional clamping up to Tj = 185 °C - preserves measurement accuracy and eliminates thermal drift-induced false triggers. |
Use Scenario: Guarding -48 V telecom rectifier outputs against lightning-induced surges in outdoor base station cabinets. IC Role / Device Role / Timing Role: Installed at power entry point, shunting surge current to chassis ground via low-inductance layout. Use Value: Delivers 600 W peak pulse handling with VCL = 26.0 V - ensures downstream DC/DC modules remain within absolute maximum ratings during 10/1000 μs threats. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | DO-214AC package (larger: 4.5 mm × 2.7 mm × 2.2 mm); VRWM = 16 V; VCL = 26.0 V @ 23.1 A; Tj max = 150 °C. | Larger footprint and lower max junction temperature limit - unsuitable for >150 °C ambient or space-constrained layouts. | Select when legacy DO-214AC compatibility or higher surge repetition tolerance is required; avoid where height <1.1 mm or Tj >150 °C is mandatory. |
| SMCJ16A | DO-214AB package (7.1 mm × 6.2 mm × 2.6 mm); same VRWM/VCL but PPPM = 1500 W; Tj max = 175 °C. | 3× higher peak power but 7× larger board area and 2.6× greater height - incompatible with SOD128 footprints and thin-profile assemblies. | Choose for higher-energy surge environments (e.g., AC mains input) where board space permits; not a drop-in replacement for PTVS16VP1UTP,115. |
Compared with SMAJ16A and SMCJ16A, PTVS16VP1UTP,115 uniquely combines SOD128 compactness, 185 °C junction rating, and 600 W capability - making it optimal for thermally dense, high-reliability industrial and automotive-adjacent systems where size and temperature margins are co-constrained.

FAQ
What is the maximum clamping voltage for PTVS16VP1UTP,115 under a 10/1000 μs surge?
The maximum clamping voltage (VCL) is 26.0 V at rated peak pulse current (IPPM) of 23.1 A, measured per IEC 61643-321 using the standard 10/1000 μs current waveform. This value is guaranteed across the full operating temperature range and represents worst-case voltage seen by downstream circuitry during surge events.
Is PTVS16VP1UTP,115 qualified for automotive use per AEC-Q101?
Yes - the device is qualified to AEC-Q101 for discrete semiconductors, as confirmed in Section 11 ("Test information") of the official Nexperia datasheet. Although revision history notes that some variants had qualification status removed, PTVS16VP1UTP,115 remains among the 33 types explicitly retained with AEC-Q101 qualification per Table 9.
How does the temperature coefficient affect clamping performance?
The temperature coefficient (SZ) is +15.9 mV/K, meaning VCL increases linearly with junction temperature. At 150 °C, VCL rises ~3.6 V above its 25 °C value - critical for worst-case analysis in high-ambient designs. This behavior is fully characterized and documented in Table 8 of the datasheet.
What is the recommended PCB layout for optimal thermal performance?
For minimal thermal resistance, connect the cathode (Pin 1) to a ≥1 cm² copper pour on an FR4 board (Rth(j-a) = 120 K/W) or use a ceramic Al2O3 substrate (Rth(j-a) = 60 K/W). The cathode tab must be soldered directly to the thermal pad; anode (Pin 2) requires low-inductance grounding to ensure fast transient response and avoid ringing.
