Product details
Overview
PTVS43VP1UP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-energy transient suppression on DC power rails. It features 43 V reverse standoff voltage (VRWM), 52.8 V maximum clamping voltage (VCL) at 69.4 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 PTVS43VP1UP,115 datasheet, PTVS43VP1UP,115 pinout, PTVS43VP1UP,115 application, or PTVS43VP1UP,115 equivalent, key selection criteria include clamping performance under IEC 61643-321 10/1000 µs waveform, thermal resistance to solder point (12 K/W), and compatibility with automated SMT reflow processes using standard CFP5 footprints.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below 43 V VRWM, then avalanches sharply at 47.8–52.8 V (VBR/VCL range) to divert transients up to 600 W (10/1000 µs). Its junction-to-solder-point thermal resistance of 12 K/W enables effective heat dissipation during repetitive surge events.
The device uses planar silicon junction technology with cathode-anode polarity defined by a marking bar on the SOD128 body. It complies with IEC 61643-321 surge testing and achieves 30 kV ESD contact discharge rating per IEC 61000-4-2 - confirming robustness against system-level electrostatic threats.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W - sustains single 10/1000 µs surges per IEC 61643-321 without degradation |
| Reverse Standoff Voltage (VRWM) | 43 V - maximum continuous DC operating voltage before leakage exceeds 0.001 µA |
| Clamping Voltage (VCL) | 52.8 V at IPPM = 69.4 A - limits downstream circuit voltage during worst-case surge |
| Breakdown Voltage (VBR) | 47.8–50.3 V at IR = 1 mA - precise avalanche onset ensures predictable protection threshold |
| Junction-to-Solder-Point Rth | 12 K/W - enables direct thermal coupling to PCB copper for reliable power cycling |
| ESD Contact Discharge | 30 kV - withstands high-energy human-body ESD events without parametric shift |
| Package Dimensions | 3.8 × 2.6 × 1.0 mm - ultra-low profile compatible with space-constrained industrial PCB layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ43A | Lower PPPM (400 W); higher VCL (69.4 V at 58.1 A); DO-214AC package (2.7 mm height) | Less effective for high-energy industrial surges; taller profile limits board stacking | Select when cost sensitivity outweighs surge margin and board height constraints |
| SMCJ43A | Higher PPPM (1500 W); same VRWM/VCL; larger SMC (DO-214AB) package (2.6 mm height) | Better for extreme surge environments but requires 3× PCB area and higher thermal mass | Choose where sustained 1500 W capability justifies footprint and assembly cost increase |
Compared with SMAJ43A and SMCJ43A, PTVS43VP1UP,115 delivers optimal balance of 600 W surge capacity, 1 mm profile, and 0.001 µA leakage - making it preferred for space-constrained industrial power modules needing repeatable, low-standby-loss protection.

FAQ
What is the maximum clamping voltage of PTVS43VP1UP,115 under rated surge conditions?
The maximum clamping voltage (VCL) is 52.8 V at 69.4 A peak pulse current (IPPM), measured per IEC 61643-321 10/1000 µs waveform. This value is guaranteed across the full operating temperature range (−55 °C to +150 °C) and defines the upper voltage limit imposed on protected circuits during surge events.
Does PTVS43VP1UP,115 require derating at elevated ambient temperatures?
Yes - its rated peak pulse power decreases with junction temperature, following a typical curve of 100% at 25 °C down to ~50% at 125 °C (per Fig. 2). Designers must apply thermal modeling using Rth(j-a) = 200 K/W (free air) or Rth(j-sp) = 12 K/W (solder point) to ensure safe operation in high-temperature enclosures.
Can PTVS43VP1UP,115 be used in bidirectional signal line protection?
No - it is a unidirectional TVS diode intended only for DC power rail protection. Its anode-cathode polarity means it conducts only during positive transients relative to ground. For bidirectional data lines (e.g., RS-485, CAN), a symmetric dual-diode array or dedicated bidirectional TVS like PTVS3V3S1UR must be selected.
What is the recommended PCB footprint for reflow soldering of PTVS43VP1UP,115?
The official reflow footprint specifies 2.5 mm × 3.4 mm solder lands with 1.9 mm × 1.9 mm solder paste openings (per Fig. 7). Copper area under the cathode pad should be ≥1 cm² for optimal thermal performance, and solder mask-defined pads are recommended to prevent bridging during high-volume SMT assembly.
