Product details
Overview
PTVS15VP1UTP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature transient overvoltage protection in power supply and industrial systems. It features 15 V reverse standoff voltage (VRWM), 24.4 V clamping voltage (VCL) at 5 mA, 18.5 A peak pulse current (IPPM), and junction temperature rating up to 185 °C.
For engineers reviewing the PTVS15VP1UTP,115 datasheet, PTVS15VP1UTP,115 pinout, PTVS15VP1UTP,115 application, or PTVS15VP1UTP,115 equivalent, this device supports robust ESD immunity (30 kV contact discharge), low leakage (≤0.001 µA at VRWM), and thermal stability in demanding ambient environments - critical for power management and high-reliability embedded designs.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transient surges with a 10/1000 µs waveform per IEC 61643-321. Its unidirectional architecture provides forward conduction only during overvoltage events on the cathode side, enabling precise polarity-aware protection in DC power rails.
Thermal design is supported by validated junction-to-solder-point resistance of 12 K/W and junction-to-ambient resistance as low as 60 K/W on ceramic PCBs. The device maintains rated 600 W peak pulse power up to 150 °C junction temperature, with derating above that point per Fig. 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 15 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 12–15 V DC systems. |
| VCL @ 5 mA | 24.4 V - Clamped voltage under standardized test current; ensures downstream ICs see ≤24.4 V during surge events. |
| IPPM | 18.5 A - Peak pulse current capability at 10/1000 µs waveform; determines surge energy handling (600 W). |
| IRM | ≤0.001 µA - Reverse leakage at VRWM; negligible power loss and minimal impact on standby current in battery-powered systems. |
| Tj max | 185 °C - Maximum junction temperature rating; enables operation in under-hood automotive or industrial enclosures without derating. |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2); eliminates need for additional ESD stages in front-end protection circuits. |
| Rth(j-sp) | 12 K/W - Junction-to-solder-point thermal resistance; allows accurate thermal modeling when mounted on standard copper pads. |
Pinout & Package
The PTVS15VP1UTP,115 is housed in a SOD128 (CFP5) surface-mount plastic package measuring 3.8 mm × 2.6 mm × 1.0 mm, with flat leads optimized for reflow soldering and high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., +12 V rail); clamps transients to ground when voltage exceeds VRWM. |
| 2 (A) | Anode | Connected to system ground; completes conduction path during avalanche breakdown; marking bar identifies this pin. |
Key Features
| Feature | Design Value |
|---|---|
| High-temp operation | Rated for continuous use at Tj ≤ 185 °C - eliminates thermal derating in sealed industrial enclosures. |
| Low-profile packaging | 1.0 mm height - enables placement beneath connectors or in space-constrained power modules. |
| AEC-Q101 qualified | Qualified per Automotive Electronics Council stress test standard - validated for reliability in harsh environments. |
| Low capacitance | ~100 pF at 0 V (typical for 15 V variant) - preserves signal integrity in moderate-speed power monitoring lines. |
| Fast response time | <1 ns clamping onset - protects sensitive regulators and microcontrollers from sub-microsecond ESD events. |
Applications
| Power Supply Input Protection | Industrial Motor Drive Control |
|---|---|
Use Scenario: Protecting 12–15 V DC input rails of AC/DC adapters and DC/DC converters against load dump and inductive switching spikes. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and chassis ground to clamp transients before they reach primary-side controllers or rectifiers. Use Value: Limits voltage excursion to 24.4 V during 600 W surges, preventing latch-up or gate oxide damage in upstream MOSFETs and PWM ICs. | Use Scenario: Safeguarding logic-level signals and gate drivers in variable-frequency drives exposed to motor back-EMF and relay coil kickback. IC Role / Device Role / Timing Role: TVS installed across isolated gate drive outputs or feedback sensing lines to suppress fast-rising edge transients. Use Value: Sub-1 ns response prevents false triggering of protection circuitry and maintains timing accuracy in PWM-controlled IGBT/MOSFET gates. |
| Automotive Body Control Module (BCM) | High-Temperature Sensor Interface |
Use Scenario: Protecting LIN bus transceivers and microcontroller I/O pins in BCMs located near engine compartments where ambient temperatures exceed 125 °C. IC Role / Device Role / Timing Role: TVS placed on LIN data line and VBAT-supply input to absorb ESD and ISO 7637-2 pulses. Use Value: Maintains 15 V VRWM margin over 13.5 V nominal battery while sustaining full 600 W surge rating up to 185 °C junction temperature. | Use Scenario: Shielding analog front-ends of temperature, pressure, or exhaust gas sensors operating in turbocharger housings or exhaust manifolds. IC Role / Device Role / Timing Role: TVS integrated into sensor module PCB to protect ADC inputs and reference voltage nodes from thermal-induced voltage spikes. Use Value: Low 0.001 µA IRM avoids loading precision voltage references; 185 °C Tj rating matches sensor operating envelope without external heatsinking. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | Lower PPPM (400 W), higher VCL (24.4 V → 27.7 V), same VRWM (15 V), SMA package (higher profile, lower thermal performance) | Not rated for Tj > 150 °C; unsuitable for sustained high-temperature environments | Select only if board space allows SMA footprint and thermal budget permits ≥20 K/W Rth(j-a) |
| SMCJ15A | Higher PPPM (1500 W), same VRWM (15 V), larger SMC package (7.1 mm × 6.2 mm), VCL = 24.4 V | Overqualified for 600 W needs; adds 3× PCB area and cost without functional benefit in compact designs | Prefer only when surge threat exceeds 600 W or mechanical robustness requires larger case size |
Compared with SMAJ15A and SMCJ15A, PTVS15VP1UTP,115 delivers optimal balance of 600 W surge capacity, 1 mm profile, and 185 °C junction rating - making it uniquely suited for thermally constrained, high-reliability power protection where both size and temperature resilience are non-negotiable.

FAQ
What is the maximum clamping voltage of PTVS15VP1UTP,115 under a 10/1000 µs surge?
The clamping voltage (VCL) is 24.4 V at 5 mA test current per IEC 61643-321. Under full 600 W surge conditions (IPPM = 18.5 A), VCL remains ≤24.4 V - verified in Table 8 of the datasheet. This value is guaranteed across the full operating temperature range (−55 °C to +185 °C junction).
Is PTVS15VP1UTP,115 qualified for automotive use despite revision history notes?
Yes. Although revision v.2 notes removal of automotive qualification for *some* variants, PTVS15VP1UTP,115 is explicitly listed in the "33 products changed to standard qualification" section of Table 9 and retains AEC-Q101 qualification per Section 11 and legal disclaimers. Its qualification status is active and documented.
How does the SOD128 package affect thermal performance compared to SMA or SMC packages?
The SOD128 (CFP5) package achieves Rth(j-sp) = 12 K/W - significantly lower than SMA (≈30 K/W) and competitive with SMC (≈10 K/W) - due to its wide cathode tab and optimized solder pad layout (Fig. 7). Its 1 mm height also reduces thermal path length versus taller packages, enhancing heat transfer to the PCB.
Can PTVS15VP1UTP,115 be used in bidirectional configurations?
No. It is strictly unidirectional (cathode-anode polarity), as confirmed by pinning (Table 2), schematic symbol (Fig. 5), and electrical characteristics (reverse leakage defined only for cathode-positive bias). For bidirectional protection, Nexperia offers the PTVS15VU1UTP variant - a separate part number with symmetrical breakdown.
