Product details
Overview
PTVS30VP1UTP,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 = 30 V, VBR(min) = 33.3 V, VCL = 48.4 V at IPPM = 12.4 A, and junction temperature rating up to 185 °C. It serves as primary clamping protection on DC power rails in industrial control modules.
For engineers reviewing the PTVS30VP1UTP,115 datasheet, PTVS30VP1UTP,115 pinout, PTVS30VP1UTP,115 application, or PTVS30VP1UTP,115 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD tolerance, thermal resistance to PCB copper area, 10/1000 µs waveform compliance per IEC 61643-321, and absence of automotive qualification per latest revision history.
Technical Context
This TVS diode operates in avalanche breakdown mode under transient stress, with unidirectional polarity requiring cathode connection to the protected line and anode to ground. Its 30 V reverse standoff voltage (VRWM) ensures stable blocking below system operating voltage, while 33.3–36.8 V breakdown range (VBR) guarantees reliable turn-on before downstream component damage.
Clamping performance is defined by 48.4 V maximum VCL at 12.4 A peak pulse current (IPPM), delivering predictable voltage limiting during 10/1000 µs surges. Temperature coefficient of breakdown voltage is +0.5 mV/K, enabling stable operation across –55 °C to +185 °C ambient range without derating loss above 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - Sustains 10/1000 µs transients per IEC 61643-321 without degradation |
| Reverse Standoff Voltage | VRWM = 30 V - Blocks normal 24 V nominal rail with 25 % margin before leakage rise |
| Breakdown Voltage | VBR = 33.3–36.8 V - Ensures conduction onset before 3.3 V logic supply or 48 V bus overvoltage damage |
| Clamping Voltage | VCL = 48.4 V @ 12.4 A - Limits surge voltage to safe level for 40 V-rated MOSFETs or 50 V capacitors |
| Junction Temperature | Tj ≤ 185 °C - Supports operation in engine bay, motor drives, and enclosed industrial enclosures |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2) - Eliminates need for secondary ESD protection on board-level inputs |
| Leakage Current | IRM = 0.001 µA @ VRWM - Negligible standby power loss in battery-powered remote sensors |
Pinout & Package
SOD128 (CFP5) plastic surface-mount package: 2-terminal, 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, marking bar denotes cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 24 V rail); marking bar aligns with this pin |
| 2 (A) | Anode | Connected to system ground; forms low-impedance path for surge current to earth |
Key Features
| Feature | Design Value |
|---|---|
| High-Temperature Stability | Rated for continuous operation at Tj = 185 °C - enables placement near heat sources without derating |
| Low Profile Packaging | 1.0 mm max height - fits under shields and in space-constrained motor controller PCBs |
| Robust Surge Handling | Withstands 100 A non-repetitive forward surge (IFSM) - survives accidental reverse-battery or load-dump events |
| Ultra-Low Leakage | 0.001 µA IRM at VRWM - preserves battery life in always-on IoT edge nodes |
| Thermal Resistance Control | Rth(j-sp) = 12 K/W to solder point - enables direct thermal coupling to large ground planes for sustained pulse dissipation |
Applications
| Industrial Motor Drives | Programmable Logic Controllers |
|---|---|
Use Scenario: Protection of 24 V DC input terminals against inductive kickback from solenoid valves and relay coils. IC Role / Device Role / Timing Role: Unidirectional clamping device placed directly at connector entry, shunting surge energy to chassis ground before reaching upstream DC-DC converter. Use Value: 48.4 V clamping voltage prevents overvoltage damage to 40 V-rated input-stage MOSFETs and maintains functional safety integrity per IEC 61800-5-2. | Use Scenario: Input protection on digital I/O modules exposed to field wiring in factory automation cabinets. IC Role / Device Role / Timing Role: Primary transient suppressor on 24 V sensor supply lines, coordinated with downstream RC filters and optocoupler isolation. Use Value: 0.001 µA leakage avoids false triggering of 24 V sink-input circuits, while 600 W rating handles long-duration surges from nearby welding equipment. |
| Power Over Ethernet (PoE) Switches | Outdoor LED Lighting Drivers |
Use Scenario: Secondary protection on 48 V PoE power sourcing equipment (PSE) output ports. IC Role / Device Role / Timing Role: Fast-response TVS placed after primary gas discharge tube (GDT), absorbing residual energy not diverted by front-end protection. Use Value: 33.3 V minimum breakdown ensures coordination with 57 V PoE open-circuit voltage, preventing premature conduction during normal operation. | Use Scenario: DC input protection for constant-current LED drivers mounted on streetlight poles subject to lightning-induced surges. IC Role / Device Role / Timing Role: First-line defense on 36–48 V DC input, mounted adjacent to bulk capacitor to minimize trace inductance during clamping. Use Value: 185 °C junction rating allows direct mounting on aluminum heatsink without thermal interface material, reducing BOM count and improving long-term reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | Lower PPPM (400 W), higher VCL (49.9 V), same VRWM (30 V), SMA package (higher Rth(j-a)) | Not rated for >150 °C operation; unsuitable for under-hood or enclosed high-temp environments | Select only if cost sensitivity outweighs thermal performance and surge margin requirements |
| 1.5KE30A | Higher VCL (49.3 V), larger DO-201 package (4.5 mm height), lower IPPM (12.1 A), no high-temp qualification | Through-hole mounting limits automated assembly; thermal resistance incompatible with compact industrial PCB layouts | Choose only for legacy through-hole designs where rework to SMD is not feasible |
Compared with SMAJ30A and 1.5KE30A, PTVS30VP1UTP,115 delivers superior thermal resilience (185 °C vs. ≤150 °C), lower profile (1.0 mm vs. ≥2.2 mm), and tighter VCL consistency (48.4 V vs. ≥49.3 V), making it optimal for modern high-density, high-temperature industrial power interfaces.

FAQ
Is PTVS30VP1UTP,115 qualified for automotive use?
No. Per the December 2025 revision history, PTVS30VP1UTP,115 is explicitly excluded from AEC-Q101 qualification and must not be used in automotive applications. The datasheet confirms removal of automotive qualification status for this part number, restricting its use to industrial, infrastructure, and commercial systems only.
What is the recommended PCB footprint for PTVS30VP1UTP,115?
The official reflow soldering footprint specifies 2.5 mm × 3.4 mm solder lands with 1.9 mm × 1.9 mm solder paste openings and 4.4 mm × 4.2 mm solder resist clearance. This layout achieves Rth(j-sp) = 12 K/W when using a single-sided FR4 board with tin-plated copper, as validated in Table 6 of the datasheet.
How does clamping voltage change with temperature?
VCL increases by approximately 0.05 V/°C above 25 °C due to positive temperature coefficient of avalanche breakdown. At 150 °C junction temperature, VCL rises to ~49.8 V at 12.4 A - still within safe margin for 50 V-rated downstream components, as confirmed in Table 8's Tj = 150 °C column.
Can PTVS30VP1UTP,115 replace PTVS30VP1UTP without suffix?
Yes. The ",115" suffix denotes tape-and-reel packaging per JEDEC standard J-STD-020; electrical, thermal, and mechanical specifications are identical to the base PTVS30VP1UTP. No design changes or requalification are required when substituting between these packaging variants.
