Product details
Overview
PTVS24VP1UTP,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 = 24 V, VBR = 26.7–29.5 V, VCL = 38.9 V at IPPM = 15.4 A (10/1000 µs), and junction temperature rating up to 185 °C. It serves as primary clamping protection on DC power rails in industrial control modules and high-reliability power management circuits.
For engineers reviewing the PTVS24VP1UTP,115 datasheet, PTVS24VP1UTP,115 pinout, PTVS24VP1UTP,115 application, or PTVS24VP1UTP,115 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD tolerance, thermal resistance under PCB copper constraints, reverse leakage at elevated ambient temperature, and compatibility with automated reflow profiles for SOD128 footprint.
Technical Context
This unidirectional TVS diode operates in avalanche breakdown mode during transients, delivering precise clamping response with low dynamic impedance. Its 1 mm profile and 3.8 mm × 2.6 mm body enable dense placement near connectors or IC power pins without compromising thermal dissipation.
The device exhibits stable performance across −55 °C to +185 °C ambient, supported by a typical thermal resistance Rth(j-sp) of 12 K/W to solder point and −0.5 mV/K temperature coefficient of clamping voltage. It complies with IEC 61643-321 (10/1000 µs waveform) and achieves 30 kV ESD contact discharge immunity per IEC 61000-4-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - sustains 10/1000 µs surge events without degradation under defined thermal conditions |
| Reverse Standoff Voltage | 24 V - maximum continuous DC operating voltage before significant leakage begins |
| Breakdown Voltage | 26.7–29.5 V - guaranteed avalanche onset range at 1 mA test current, defining clamping threshold |
| Clamping Voltage | 38.9 V at 15.4 A - maximum voltage seen by protected circuit during rated surge, critical for downstream IC survival |
| Reverse Leakage | 0.001 µA at 24 V - negligible standby current enabling use in ultra-low-power systems |
| Junction Temperature Limit | 185 °C - enables operation in engine bay, motor drives, and other high-ambient environments |
| ESD Rating | 30 kV contact discharge - exceeds IEC 61000-4-2 Level 4 for robust system-level ESD immunity |
Pinout & Package
PTVS24VP1UTP,115 uses the CFP5 (SOD128) surface-mount plastic package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat lead construction optimized for thermal conduction via cathode pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., +24 V rail); marking bar identifies this terminal; carries full surge current during clamping |
| 2 (A) | Anode | Connected to ground reference; forms low-impedance path to earth during transient; requires low-inductance layout |
Key Features
| Feature | Design Value |
|---|---|
| High-Temperature Stability | Rated for continuous operation at Tj ≤ 185 °C and Tamb ≤ 185 °C - eliminates derating concerns in sealed enclosures or near heat sources |
| Low Profile Packaging | 1 mm height - allows placement under shields or in space-constrained locations without mechanical interference |
| Automotive-Qualified Construction | AEC-Q101 qualified - validated for vibration, thermal cycling, and humidity resistance required in automotive ECUs and ADAS modules |
| Precision Clamping Margin | VCL − VRWM = 14.9 V - provides 62 % headroom above standoff voltage, ensuring safe margin for 24 V nominal systems with ripple and tolerance |
| Ultra-Low Capacitance | ~12 pF at 0 V (typical) - minimizes signal distortion on data lines when used in combined power/signal protection schemes |
Applications
| Industrial Motor Drive Protection | Programmable Logic Controller (PLC) Power Input |

Use Scenario: 24 V DC input stage of an IP67-rated servo drive exposed to inductive kickback and lightning-induced surges on factory floor wiring. IC Role / Device Role / Timing Role: Primary clamping element placed directly at connector entry, shunting >95 % of surge energy to chassis ground before reaching DC-DC converter ICs. Use Value: 38.9 V clamping ensures downstream 40 V-rated buck controllers remain within absolute maximum ratings during 1 kV/500 A surge events. |
Use Scenario: 24 V auxiliary supply rail in modular PLC backplane, subject to hot-swap transients and field-wiring faults. IC Role / Device Role / Timing Role: Fast-response overvoltage clamp positioned upstream of fuse and input filter, reacting within <1 ns to limit voltage overshoot. Use Value: 0.001 µA IR at 24 V prevents measurable load on always-on backup circuits, preserving battery runtime in fail-safe monitoring paths. |
| Railway Signaling Power Interface | Outdoor Telecom Remote Radio Unit (RRU) |
|

Use Value: 30 kV ESD rating and 185 °C Tj capability eliminate need for external heatsinking or derating in unventilated cabinets. |
Use Scenario: DC power input of outdoor 5G RRU powered via 24 V PoE++ or local rectifier, subjected to solar-heated enclosures and lightning coupling. IC Role / Device Role / Timing Role: Standalone TVS on main 24 V bus, sized to absorb repetitive 10/1000 µs surges without parameter drift over 15-year field life. Use Value: Stable 12 K/W Rth(j-sp) enables direct thermal coupling to aluminum housing, maintaining <125 °C junction temp under worst-case 600 W pulse duty cycle. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | Lower PPPM (400 W), higher VCL (43.5 V), larger SMA package (2.5 mm height) | Limited to ≤125 °C ambient; unsuitable for sealed high-temp enclosures | Select only if cost sensitivity outweighs thermal and clamping performance requirements |
| SMCJ24A | Higher PPPM (1500 W), same VCL (38.9 V), larger SMC package (2.3 mm height) | Requires 3× PCB area; excessive for 24 V rail where 600 W is sufficient | Choose only when legacy board design mandates SMC footprint or surge threat level exceeds 600 W |
Compared with SMAJ24A and SMCJ24A, PTVS24VP1UTP,115 delivers optimal balance of compactness, high-temperature resilience, and precise clamping-enabling smaller thermal pads, simpler layout, and assured operation in environments where ambient exceeds 125 °C.

FAQ
What is the maximum allowable PCB copper area for optimal thermal performance?
For best thermal resistance, the cathode pad should be connected to a ≥1 cm² single-sided copper pour on FR4, achieving Rth(j-a) ≈ 120 K/W. Using a ceramic substrate (Al₂O₃) reduces Rth(j-a) to 60 K/W. Smaller pads increase junction temperature rise during repeated surges and must be evaluated against peak pulse duty cycle.
Does the 185 °C junction rating apply to continuous DC operation or only transient conditions?
The 185 °C rating applies to both continuous DC operation and transient conditions. At Tamb = 185 °C, the device maintains VRWM = 24 V and IR ≤ 0.001 µA, verified per AEC-Q101 stress testing. Continuous power dissipation must still respect Rth(j-a) limits to avoid exceeding Tj = 185 °C under steady-state load.
Can PTVS24VP1UTP,115 be used in bidirectional configurations?
No-it is strictly unidirectional. Connecting it in reverse (anode to positive rail) results in forward conduction at ~0.7 V, causing catastrophic failure under normal bias. For bidirectional protection, two devices must be used in series opposition or a dedicated bidirectional TVS (e.g., PTVS24VU1UTP) selected.
How does clamping voltage change with junction temperature?
VCL exhibits a negative temperature coefficient of approximately −0.5 mV/K. At Tj = 150 °C, VCL drops ~15 V versus 25 °C value-e.g., from 38.9 V to ~37.4 V. This improves protection margin at high temperature but requires verification against minimum downstream IC withstand voltage at elevated Tj.
