Product details
Overview
PTVS15VP1UP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-energy transient overvoltage protection on DC power rails. It features a 15 V reverse standoff voltage (VRWM), 17.6 V typical breakdown voltage (VBR), 24.4 V clamping voltage (VCL) at 24.6 A peak pulse current (IPPM), and <0.001 µA reverse leakage at VRWM - suitable for protecting automotive and industrial 12 V system interfaces against IEC 61000-4-5 surges.
For engineers reviewing the PTVS15VP1UP,115 datasheet, PTVS15VP1UP,115 pinout, PTVS15VP1UP,115 application, or PTVS15VP1UP,115 equivalent, key selection criteria include clamping performance under 10/1000 µs waveform, thermal resistance to solder point (12 K/W), AEC-Q101 qualification status, and compatibility with surface-mounted 12 V power rail layouts requiring low-profile (<1 mm height) protection.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below VRWM = 15 V, then avalanches sharply at VBR ≈ 17.6 V to divert surge current away from downstream circuitry. Its 600 W peak pulse power rating is defined per IEC 61643-321 using 10/1000 µs waveform, with clamping voltage stabilized at 24.4 V up to IPPM = 24.6 A.
Thermal design relies on low junction-to-solder-point resistance (Rth(j-sp) = 12 K/W), enabling effective heat transfer through the cathode tab into PCB copper. The device's 0.001 µA IRM at VRWM ensures minimal standby power loss, while its 30 kV ESD rating (IEC 61000-4-2 contact discharge) supports robust front-end immunity in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - sustains 10/1000 µs transients without failure per IEC 61643-321 |
| Reverse Standoff Voltage | VRWM = 15 V - maximum continuous DC voltage before significant leakage begins |
| Breakdown Voltage | VBR = 16.7–18.5 V @ 1 mA - precise avalanche onset threshold for predictable clamping |
| Clamping Voltage | VCL = 24.4 V @ IPPM = 24.6 A - limits protected node voltage during worst-case surge |
| Reverse Leakage | IRM ≤ 0.001 µA @ VRWM - negligible standby current in 12 V systems |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2) - withstands human-body-level static events |
| Junction Temp Limit | Tj(max) = 150 °C - supports operation in under-hood or industrial ambient conditions |
Pinout & Package
PTVS15VP1UP,115 uses the SOD128 (CFP5) surface-mount plastic package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat lead profile optimized for automated placement and reflow. Cathode identified by marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., 12 V rail); carries full surge current during clamping |
| 2 | Anode (A) | Connected to ground reference; forms low-inductance return path for transient energy |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power supply applications per stress test standard for discrete semiconductors |
| Low-profile SOD128 package | 1.0 mm max height enables use in space-constrained modules (e.g., ECUs, ADAS sensors) |
| High surge current handling | IPPM = 24.6 A enables protection against ISO 7637-2 Pulse 1/2b/5a in 12 V systems |
| Ultra-low leakage | IRM ≤ 0.001 µA minimizes quiescent power draw in always-on vehicle subsystems |
| Robust thermal path | Rth(j-sp) = 12 K/W allows direct heat conduction from junction to PCB copper via cathode tab |
Applications
| Automotive Body Control Module | Industrial PLC Input Protection |
|---|---|

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 | Same VRWM (15 V), but lower PPPM = 400 W; SMA package (higher Rth(j-a) = 50 K/W) | Limited to lower-energy transients; less suitable for automotive load dump compliance | Prefer PTVS15VP1UP,115 where 600 W rating and AEC-Q101 are required |
| SMCJ15A | Same VRWM (15 V), higher PPPM = 1500 W; larger SMC package (7.1 mm × 6.2 mm) | Better surge margin but incompatible with space-constrained SOD128 footprints | Choose PTVS15VP1UP,115 when board area is constrained and 600 W suffices |
Compared with SMAJ15A and SMCJ15A, PTVS15VP1UP,115 delivers optimal balance of AEC-Q101 qualification, 600 W surge capability, and ultra-compact SOD128 footprint - making it ideal for modern automotive and industrial modules where size, reliability, and standardized qualification are jointly critical.

FAQ
Is PTVS15VP1UP,115 AEC-Q101 qualified?
Yes. PTVS15VP1UP,115 is qualified per AEC-Q101 for discrete semiconductors, as confirmed in the revision history (v.3, December 2025) which explicitly lists it among the 25 products changed to standard automotive qualification. This qualification covers temperature cycling, humidity testing, and surge endurance relevant to automotive under-hood environments.
What is the clamping voltage at rated peak pulse current?
At IPPM = 24.6 A (10/1000 µs waveform), the clamping voltage VCL is 24.4 V maximum. This value is measured per IEC 61643-321 and guarantees that downstream components with ≤25 V absolute maximum ratings remain protected during worst-case surge events.
Can PTVS15VP1UP,115 be used in bidirectional configurations?
No. PTVS15VP1UP,115 is a unidirectional TVS diode with anode and cathode terminals. It conducts only during positive transients on the cathode side relative to anode. For bidirectional protection (e.g., data lines), two devices or a dedicated bidirectional TVS like PTVS15VB1UP would be required.
How does thermal resistance affect PCB layout?
With Rth(j-sp) = 12 K/W, optimal thermal performance requires maximizing copper area connected to the cathode pad (Pin 1). The datasheet recommends ≥1 cm² tin-plated copper for cathode mounting; insufficient copper increases junction temperature, derating peak pulse power per Fig. 2 and risking thermal runaway during repeated surges.
