Product details
Overview
PTVS24VP1UP,115 from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for robust overvoltage protection in DC power rails. It features a 24 V reverse standoff voltage (VRWM), 29.5 V maximum clamping voltage (VCL) at 38.9 A peak pulse current, and 0.001 µA reverse leakage at VRWM - enabling low-power system integrity in automotive and industrial power management circuits.
For engineers reviewing the PTVS24VP1UP,115 datasheet, PTVS24VP1UP,115 pinout, PTVS24VP1UP,115 application, or PTVS24VP1UP,115 equivalent, key selection criteria include clamping performance under IEC 61643-321 10/1000 µs surge, thermal resistance to solder point (12 K/W), AEC-Q101 qualification status, and compatibility with high-density SMT layouts requiring ≤1 mm profile.
Technical Context
This unidirectional TVS diode operates as a shunt protector: it remains high-impedance below 24 V VRWM, then avalanches sharply at 26.7–29.5 V breakdown (VBR), limiting transient energy by diverting up to 38.9 A (IPPM) while clamping output to ≤29.5 V. Its response is governed by junction avalanche physics, not active control logic.
Thermal design is critical: Rth(j-sp) = 12 K/W enables effective heat transfer from junction to cathode solder point, while Rth(j-a) = 200 K/W in free air confirms dependency on PCB copper area for sustained surge handling. Pulse power derating follows Fig. 2 - PPPM drops to ~50% at Tj = 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W per IEC 61643-321 (10/1000 µs); defines maximum single-surge energy absorption capability |
| Reverse Standoff Voltage (VRWM) | 24 V; maximum continuous DC voltage before significant leakage - sets operating margin for 24 V nominal systems |
| Clamping Voltage (VCL) | 29.5 V at IPPM = 38.9 A; maximum voltage seen by protected circuit during worst-case surge |
| Breakdown Voltage (VBR) | 26.7–29.5 V at IR = 1 mA; ensures reliable turn-on before VCL exceeds downstream IC absolute max ratings |
| Reverse Leakage (IRM) | 0.001 µA at VRWM; negligible standby current draw - critical for battery-backed or ultra-low-power systems |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2); provides system-level ESD immunity without additional front-end protection |
| Package Thermal Resistance | Rth(j-sp) = 12 K/W; enables direct thermal coupling to PCB copper, supporting repeated surge events in compact layouts |
Pinout & Package
PTVS24VP1UP,115 uses the SOD128 (CFP5) surface-mount package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat lead construction optimized for automated reflow. The cathode is marked by a bar on the package top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., +24 V rail); carries full surge current during clamping |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance return path for transient energy dissipation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability (temperature cycling, HTRB, ESD), supporting deployment in engine control and body electronics |
| 1 mm profile | Enables use in space-constrained modules (e.g., ADAS ECUs, motor drivers) where height clearance is limited to <1.2 mm |
| Low IRM (0.001 µA) | Minimizes quiescent power loss in always-on 24 V systems - avoids battery drain in parked vehicle scenarios |
| 600 W surge rating | Meets ISO 7637-2 Pulse 1/2a/5a requirements for 24 V automotive systems without cascaded protection stages |
| SOD128 footprint | Standardized land pattern (Fig. 7) ensures compatibility with existing reflow processes and AOI inspection systems |
Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
|
Use Scenario: Protecting 24 V supply inputs of engine control units (ECUs) against load dump transients (ISO 7637-2 Pulse 5a). IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed directly across input terminals to clamp surges within 1 ns. Use Value: Limits voltage to ≤29.5 V during 38.9 A pulses, preventing damage to upstream DC-DC converters and microcontrollers rated for 36 V abs max. |
Use Scenario: Safeguarding analog input channels (e.g., 4–20 mA sensors) in programmable logic controllers against field-wiring induced surges. IC Role / Device Role / Timing Role: Front-end transient suppressor mounted at connector entry point, before signal conditioning circuitry. Use Value: 0.001 µA leakage avoids offset errors in precision current loops; 29.5 V clamping protects op-amps and ADCs with 30 V supply rails. |
| Telecom Power Supply Protection | Motor Drive DC Bus Clamping |
|
Use Scenario: Securing primary-side 24 V bias supplies in telecom base station power modules exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Primary-stage TVS on bulk capacitor input, coordinated with upstream fuses and MOVs. Use Value: 600 W rating handles multi-pulse surge sequences per IEC 61000-4-5; 30 kV ESD rating eliminates need for secondary ESD diodes. |
Use Scenario: Suppressing inductive kickback spikes on 24 V DC bus lines feeding brushed DC motors in factory automation actuators. IC Role / Device Role / Timing Role: Bidirectional clamping is unnecessary - unidirectional placement leverages lower VBR tolerance for tighter voltage control. Use Value: 26.7–29.5 V VBR range ensures predictable turn-on before MOSFET drain-source breakdown, reducing snubber losses. |

FAQ
What is the maximum clamping voltage of PTVS24VP1UP,115 at its rated peak pulse current?
The maximum clamping voltage (VCL) is 29.5 V at IPPM = 38.9 A, measured per IEC 61643-321 10/1000 µs waveform. This value ensures protected circuits remain below 30 V during worst-case surge events, aligning with common 3.3 V/5 V/24 V system IC absolute maximum ratings.
Is PTVS24VP1UP,115 still qualified to AEC-Q101 for automotive applications?
Yes - PTVS24VP1UP,115 retains AEC-Q101 qualification as confirmed in Section 11 ("Test information") of the December 2025 datasheet. Unlike some variants removed from automotive status in Revision v.3, this part remains approved for automotive use per Nexperia's official qualification records.
How does the SOD128 package affect thermal performance in high-surge applications?
The SOD128 package delivers Rth(j-sp) = 12 K/W to the cathode solder point, enabling efficient heat extraction into PCB copper. When mounted on ≥1 cm² cathode pad (per Table 6 Note [2]), it sustains repeated 600 W surges without thermal runaway - critical for automotive load-dump protection where multiple pulses may occur.
Can PTVS24VP1UP,115 replace older P6SMB24A devices in existing designs?
PTVS24VP1UP,115 offers superior performance vs. P6SMB24A: lower VCL (29.5 V vs. 38.9 V), smaller SOD128 vs. DO-214AA package, and AEC-Q101 qualification. However, pinout differs (SOD128 cathode/anode vs. DO-214AA anode/cathode), requiring layout revision and polarity verification before drop-in replacement.
