Product details
Overview
PTVS43VP1UTP,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 = 43 V, VBR(min) = 47.8 V, VCL = 69.4 V at IPPM = 8.6 A (10/1000 μs), and junction temperature rating up to 185 °C. It serves as primary clamping protection on DC power rails in industrial power supplies and harsh-environment control modules.
For engineers reviewing the PTVS43VP1UTP,115 datasheet, PTVS43VP1UTP,115 pinout, PTVS43VP1UTP,115 application, or PTVS43VP1UTP,115 equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, thermal resistance to solder point (Rth(j-sp) = 12 K/W), reverse leakage at 150 °C (<0.1 µA), and AEC-Q101 qualification status per revision history.
Technical Context
This unidirectional TVS diode operates in avalanche breakdown mode during transients, with a defined clamping characteristic that limits voltage across protected circuitry to ≤69.4 V under 8.6 A peak pulse current (10/1000 μs waveform per IEC 61643-321). Its low-profile SOD128 package enables placement near connectors or input terminals where board space and height are constrained.
Thermal performance is optimized for high ambient operation: Rth(j-a) = 200 K/W (FR4, standard footprint), Rth(j-sp) = 12 K/W (cathode solder point), enabling sustained reliability at Tamb up to 185 °C. Temperature coefficient of breakdown voltage is +0.5 mV/K, ensuring stable clamping behavior across its full operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 43 V - Maximum continuous reverse working voltage before significant leakage; sets upper limit for protected rail voltage. |
| VBR (min) | 47.8 V - Minimum breakdown voltage at 1 mA; ensures reliable conduction onset above normal operating voltage. |
| VCL | 69.4 V - Clamped voltage at 5 mA test current; defines worst-case overvoltage seen by downstream circuitry. |
| PPPM | 600 W - Peak pulse power handling (10/1000 μs); determines survivability against common surge events like ISO 7637-2 Pulse 1/2a. |
| IRM | 0.001 µA - Reverse leakage at VRWM and 25 °C; negligible loading on low-power supply rails. |
| Tj(max) | 185 °C - Maximum junction temperature; supports operation in engine bay, motor drives, and industrial enclosures without derating. |
| Rth(j-sp) | 12 K/W - Thermal resistance to cathode solder point; enables efficient heat transfer into PCB copper, critical for repeated surge duty. |
Pinout & Package
PTVS43VP1UTP,115 is housed in a SOD128 (CFP5) surface-mount plastic package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat lead profile with cathode marked by a bar. The package supports reflow and wave soldering per IPC-J-STD-020 and IPC-J-STD-006 footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected circuit's ground or low-side reference; carries full surge current during clamping. |
| 2 | Anode (A) | Connected to the line being protected (e.g., +43 V rail); reverse-biased during normal operation. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature stability | Junction rated to 185 °C with <0.1 µA IR at 150 °C - maintains protection integrity in under-hood or enclosed industrial environments. |
| Low-profile SMD package | 1.0 mm max height - fits beneath shields and in tight spacing near I/O connectors without mechanical interference. |
| AEC-Q101 qualified | Listed in revision history v.2 (20251201) as qualified - validated for automotive-grade reliability including HTGB, HTRB, and ESD testing. |
| Low clamping ratio | VCL/VBR = 69.4/47.8 ≈ 1.45 - tight voltage margin preserves headroom for downstream 75 V-rated components. |
| ESD robustness | 30 kV contact discharge (IEC 61000-4-2), >8 kV HBM - protects against handling and system-level ESD without external shielding. |
Applications
| Industrial Power Supply Protection | Motor Drive Control Module |

Use Scenario: 48 V DC input stage of programmable logic controller (PLC) power module exposed to load dump and inductive switching surges. IC Role / Device Role / Timing Role: Primary unidirectional clamping device placed directly at connector entry, shunting surge energy to chassis ground before it reaches DC-DC converters and microcontrollers. Use Value: Limits transient voltage to ≤69.4 V, protecting 75 V-rated MOSFETs and 5 V LDOs while maintaining 185 °C operational capability in sealed enclosures. |
Use Scenario: Gate driver supply rail in 3-phase inverter for HVAC compressors operating in high-ambient-temperature environments. IC Role / Device Role / Timing Role: Secondary overvoltage clamp on isolated 15 V gate drive supply, triggered only during fast dv/dt events from shoot-through or parasitic oscillation. Use Value: Sub-1 mm profile allows placement adjacent to isolated DC-DC transformer; 12 K/W Rth(j-sp) prevents thermal runaway during repetitive 100 Hz surge events. |
| Telecom Remote Radio Unit (RRU) | Energy Meter Front-End Protection |
|
Use Scenario: -48 V DC power input of outdoor 5G RRU subjected to lightning-induced surges and AC coupling transients. IC Role / Device Role / Timing Role: First-line TVS in series with upstream fuse and downstream π-filter; activated within nanoseconds to suppress 10/1000 μs surges per IEC 61643-321. Use Value: 600 W PPPM rating handles multiple surge events without degradation; 0.001 µA IR avoids loading sensitive monitoring circuits during standby. |
Use Scenario: M-Bus or PLC communication interface on smart electricity meter installed in utility cabinets with wide ambient swings (-40 °C to +85 °C). IC Role / Device Role / Timing Role: Bidirectional-capable protection element (used unidirectionally) on 12 V auxiliary supply, guarding against EFT bursts and capacitor discharge events. Use Value: AEC-Q101 qualification ensures long-term reliability under thermal cycling; marking code "CZ" enables traceable field replacement and BOM verification. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ43A | Same VRWM (43 V), but lower PPPM (400 W), higher VCL (72.7 V), and SMC package (2.4 mm height). | Limited to lower-energy transients; unsuitable for repeated 600 W surges or space-constrained layouts. | Select only if cost sensitivity outweighs surge margin and board height constraints. |
| SMCJ43A | Higher PPPM (1500 W), same VRWM, but larger SMC package (7.1 mm × 6.2 mm × 2.6 mm) and higher Rth(j-a) (35 K/W). | Better single-event energy handling, but requires more PCB area and less effective thermal coupling than SOD128. | Prefer when surge amplitude exceeds 600 W but board height and thermal path are not limiting. |
Compared with SMAJ43A and SMCJ43A, PTVS43VP1UTP,115 delivers optimal balance of 600 W surge capacity, ultra-low 1 mm profile, and 12 K/W thermal resistance to solder point-making it uniquely suited for compact, high-temperature, high-reliability power rail protection where both space and thermal management are critical.

FAQ
Is PTVS43VP1UTP,115 qualified for automotive use?
Yes. Per the revision history (v.2, 20251201), PTVS43VP1UTP,115 is explicitly listed among the 33 types granted AEC-Q101 qualification. This includes stress testing per HTGB, HTRB, and ESD protocols, confirming suitability for automotive powertrain and body electronics applications.
What is the maximum surge current this TVS can handle?
At VRWM = 43 V, the rated peak pulse current IPPM is 8.6 A for the standardized 10/1000 μs waveform per IEC 61643-321. This corresponds to the 600 W peak pulse power rating; actual current depends on clamping voltage and waveform shape, but 8.6 A is the validated test condition.
How does the 1 mm package height impact PCB layout?
The SOD128 package's 1.0 mm maximum height enables placement beneath metal shields, in narrow keep-out zones near board edges, and directly adjacent to high-speed connectors-reducing inductance in the surge current path and improving clamping response time without compromising mechanical clearance in stacked or enclosed assemblies.
Can this TVS be used in bidirectional configurations?
No. PTVS43VP1UTP,115 is a unidirectional device with anode and cathode terminals. Its electrical characteristics-including breakdown and clamping-are specified only for reverse-biased operation. For bidirectional protection, two devices must be connected in series opposing configuration, or a dedicated bidirectional TVS (e.g., PTVS43VS1UTP) should be selected.
