Product details
Overview
PTVS14VP1UTP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature transient overvoltage protection in automotive power rails. It features VRWM = 14 V, VBR(min) = 15.6 V, VCL(max) = 23.2 V at IPPM = 25.9 A, and operates up to Tj = 185 °C.
For engineers reviewing the PTVS14VP1UTP-QX datasheet, PTVS14VP1UTP-QX pinout, PTVS14VP1UTP-QX application, or PTVS14VP1UTP-QX equivalent, key selection criteria include clamping voltage under 24 V, peak pulse current capability above 25 A, AEC-Q101 qualification, and thermal stability beyond 175 °C ambient in engine bay or battery management systems.
Technical Context
This TVS diode uses a planar silicon junction structure optimized for low dynamic impedance during 10/1000 µs transients per IEC 61643-321. Its unidirectional configuration provides reverse-biased clamping only, with cathode-anode polarity defined by the marking bar.
Thermal design relies on low Rth(j-sp) = 12 K/W to solder point and supports continuous operation at Tamb = 185 °C when mounted on ceramic PCB or with enhanced copper pour. ESD robustness includes ±30 kV contact discharge per IEC 61000-4-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W - sustains 10/1000 µs surge without degradation at Tj ≤ 25 °C |
| Reverse Standoff Voltage | 14 V - maximum continuous DC or RMS voltage before significant leakage |
| Breakdown Voltage | 15.6–17.2 V - voltage at 1 mA IR where clamping initiates reliably |
| Clamping Voltage | 23.2 V max at 25.9 A - limits downstream IC voltage during worst-case surge |
| Junction Temperature | 185 °C max - enables placement near heat sources like power converters or motors |
| ESD Rating | ±30 kV contact discharge - exceeds automotive infotainment and sensor interface requirements |
| AEC-Q101 Qualified | Yes - validated for automotive discrete semiconductor stress testing including HTGB, HTRB, and temperature cycling |
Pinout & Package
SOD128 (CFP5) surface-mount plastic package: 2-terminal, 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat lead profile optimized for automated reflow assembly and thermal conduction via cathode pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line; marking bar identifies this terminal; carries full surge current during clamping |
| 2 | Anode (A) | Connected to ground reference; forms low-impedance path to earth during transient events |
Key Features
| Feature | Design Value |
|---|---|
| High-Temperature Operation | Tj up to 185 °C enables direct mounting on power modules or near inverters without derating |
| Low Profile Height | 1.0 mm max height avoids interference with shields or stacked components in compact ECUs |
| Automotive Qualification | AEC-Q101 qualified - meets stress test requirements for under-hood and battery-connected applications |
| Stable Clamping Performance | VCL variation < ±5 % across –55 °C to 150 °C ensures predictable protection in extreme environments |
| Low Leakage Current | IRM = 0.001 µA at VRWM reduces standby power loss in always-on vehicle networks |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Battery Management System (BMS) |
|---|---|
Use Scenario: Protects 12 V supply rail against load dump (ISO 7637-2 Pulse 5a) and alternator transients in gasoline/diesel ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery feed and input filter capacitor; clamps within 1 ns to limit voltage to <24 V. Use Value: Prevents damage to MCU, CAN transceivers, and analog front-ends during 120 V/50 ms surges with no degradation after repeated events. |
Use Scenario: Shields BMS monitoring ICs and cell-balancing circuits from switching noise and hot-plug transients during 48 V mild-hybrid battery connection. IC Role / Device Role / Timing Role: Reverse-biased clamp on high-side sense rail; absorbs 600 W pulses while maintaining <1 µA leakage at 14 V nominal. Use Value: Enables reliable voltage measurement accuracy under thermal cycling from –40 °C to 125 °C ambient without parameter drift. |
| ADAS Camera Module Power Line | Electric Power Steering (EPS) Motor Driver |

IC Role / Device Role / Timing Role: First-line protection on 5 V or 3.3 V rail; responds faster than ferrite beads or MLCCs to sub-nanosecond ESD strikes. Use Value: Delivers ±30 kV contact ESD immunity without latch-up or parametric shift, preserving signal integrity in GMSL or FPD-Link interfaces. |
Use Scenario: Safeguards gate drivers and current-sense amplifiers from inductive kickback during MOSFET commutation in 12 V EPS motor control. IC Role / Device Role / Timing Role: Parallel-mounted TVS on half-bridge low-side source node; diverts >25 A spikes away from sensitive analog circuitry. Use Value: Maintains clamping voltage below 23.2 V even at 185 °C junction temperature, preventing false overvoltage faults during sustained torque demand. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ14A-Q | Lower PPPM (400 W), higher VCL (25.1 V), same SOD-123 package but not AEC-Q101 qualified | Limited to non-safety-critical cabin electronics; insufficient for load dump in engine bay | Select only for cost-sensitive interior modules where 185 °C operation and AEC-Q101 are not required |
| TPSMD14C | Same VRWM (14 V) and VCL (23.2 V), but rated for 150 °C Tj only and lacks IEC 61000-4-2 ESD validation | Not suitable for under-hood deployment; requires additional external ESD protection | Use only in controlled-temperature industrial controls where automotive qualification is unnecessary |
Compared with SMAJ14A-Q and TPSMD14C, PTVS14VP1UTP-QX uniquely delivers 600 W surge handling, full AEC-Q101 compliance, and guaranteed operation up to 185 °C - making it the only choice for thermally demanding automotive power nodes requiring zero derating.

FAQ
What is the maximum clamping voltage of PTVS14VP1UTP-QX at its rated peak pulse current?
The maximum clamping voltage (VCL) is 23.2 V at IPPM = 25.9 A, measured under 10/1000 µs waveform per IEC 61643-321. This value is guaranteed across the full operating temperature range from –55 °C to 150 °C and defines the upper voltage limit imposed on protected circuitry during surge events.
Does PTVS14VP1UTP-QX require derating at elevated ambient temperatures?
Yes - its rated peak pulse power decreases with junction temperature, dropping to ~75 % of 600 W at Tj = 150 °C and ~50 % at Tj = 175 °C (per Fig. 2). Effective thermal design using the cathode solder pad (Rth(j-sp) = 12 K/W) is essential to maintain performance in high-ambient environments like engine compartments.
How is polarity identified on the PTVS14VP1UTP-QX package?
Polarity is marked by a visible bar on the top surface of the SOD128 package, aligned with Pin 1 (cathode). The cathode must be connected to the line being protected, and the anode to system ground - reversing this connection disables clamping functionality and may cause catastrophic failure during overvoltage events.
Is PTVS14VP1UTP-QX compatible with standard reflow soldering profiles?
Yes - it is qualified for lead-free reflow per J-STD-020, with peak temperature tolerance up to 260 °C. The recommended footprint matches the CFP5 outline in Figure 7, using 2.5 mm × 3.4 mm solder lands with 1.2 mm spacing, ensuring mechanical reliability and optimal thermal transfer during assembly.
