Product details
Overview
PTVS15VP1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at 15 V reverse standoff voltage (VRWM), with 18.5 V clamping voltage (VCL) at 24.4 A peak pulse current (IPPM), and 0.001 µA reverse leakage (IRM). It protects power rails in engine control units, body electronics, and infotainment power supplies.
For engineers reviewing the PTVS15VP1UP-QX datasheet, PTVS15VP1UP-QX pinout, PTVS15VP1UP-QX application, or PTVS15VP1UP-QX equivalent, key selection criteria include VRWM tolerance, VCL margin relative to protected IC VDD, AEC-Q101 qualification status, thermal resistance to solder point (Rth(j-sp) = 12 K/W), and low-profile 1 mm height for space-constrained PCB layouts.
Technical Context
This unidirectional TVS diode operates as a shunt protector: under normal bias it presents high impedance (IRM ≤ 0.001 µA at VRWM = 15 V), but triggers avalanche conduction when transient voltage exceeds its breakdown threshold (VBR min = 16.7 V), clamping the line to ≤18.5 V within nanoseconds. Its IEC 61643-321-compliant 10/1000 µs waveform rating ensures robustness against load dump and ISO 7637-2 pulses.
Thermally, it leverages low Rth(j-sp) = 12 K/W to dissipate 600 W peak pulses without junction overheating, supported by AEC-Q101 qualification for operation from −55 °C to +150 °C ambient. The cathode-marked SOD128 package enables automated placement and reflow compatibility per JEDEC J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 15 V - Maximum continuous reverse operating voltage before leakage rises; sets upper limit for protected rail voltage. |
| VBR (min) | 16.7 V - Minimum breakdown voltage at 1 mA; defines earliest conduction onset during transients. |
| VCL @ IPPM | 18.5 V - Clamped voltage at 24.4 A peak pulse; must stay below absolute max rating of downstream ICs. |
| PPPM | 600 W - Peak pulse power handling per IEC 61643-321 (10/1000 µs); determines survivability of severe load-dump events. |
| IRM | 0.001 µA - Reverse leakage at VRWM; negligible power loss and signal integrity impact in standby. |
| Rth(j-sp) | 12 K/W - Thermal resistance from junction to solder point; enables rapid heat transfer to PCB copper for repeated surge handling. |
| AEC-Q101 | Qualified - Certified for automotive discrete semiconductors; supports PPAP documentation and long-term reliability in vehicle ECUs. |
Pinout & Package
PTVS15VP1UP-QX uses the SOD128 (CFP5) surface-mount plastic package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat leads, and cathode indicated by a marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 15 V supply rail); conducts avalanche current to ground during overvoltage. |
| 2 (A) | Anode | Connected to system ground; completes shunt path for transient energy dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power | Withstands ISO 7637-2 Pulse 5a load dump surges without degradation in automotive 12 V systems. |
| 1 mm package height | Enables use in ultra-low-profile modules such as ADAS camera housings and compact ECU enclosures. |
| AEC-Q101 qualification | Validated for temperature cycling, humidity bias, and mechanical shock per automotive reliability standards. |
| 0.001 µA reverse leakage | Minimizes quiescent current draw in always-on vehicle networks (e.g., CAN wake-up lines). |
| 12 K/W junction-to-solder-point Rth | Supports >1000 surge cycles at 50% PPPM without thermal runaway when mounted on ≥1 cm² cathode pad. |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Infotainment Power Rail |
|---|---|
Use Scenario: Protects 15 V main supply input of gasoline/diesel engine control units against alternator load dump transients up to ±120 V. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed directly at ECU connector entry point, ahead of DC-DC converters and microcontrollers. Use Value: Clamps transients to 18.5 V within <1 ns, preventing latch-up or gate oxide damage in 3.3 V/5 V logic ICs powered from the same rail. |
Use Scenario: Safeguards 15 V power input to head unit mainboard exposed to battery voltage spikes during jump-start or relay switching. IC Role / Device Role / Timing Role: Primary overvoltage clamp on fused 15 V distribution net feeding audio amplifiers, display drivers, and USB-C PD controllers. Use Value: 0.001 µA leakage avoids measurable battery drain in parked vehicle mode; 1 mm height accommodates tight stack-up under metal shielding. |
| Body Control Module (BCM) LIN Bus Supply | Automotive Telematics Power Interface |
Use Scenario: Guards 15 V supply to LIN transceivers and smart sensors in door modules and lighting controllers during electromagnetic interference events. IC Role / Device Role / Timing Role: Localized TVS adjacent to LIN physical layer ICs, minimizing trace inductance between clamp and protected node. Use Value: Low Rth(j-sp) = 12 K/W ensures stable clamping performance across −40 °C to +125 °C ambient, critical for exterior BCM operation. |
Use Scenario: Shields 15 V input of cellular/V2X telematics modules from ignition noise and antenna coupling-induced surges in roof-mounted antennas. IC Role / Device Role / Timing Role: First-line defense at module edge connector, coordinated with π-filter EMI suppression for broadband transient rejection. Use Value: AEC-Q101 qualification guarantees functional safety compliance (ISO 26262 ASIL-B support) for connected vehicle data integrity. |
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-Q | Lower PPPM (400 W), higher VCL (24.4 V), same VRWM (15 V), SMA package (2.5 mm height) | Marginally adequate for mild transients; insufficient for full ISO 7637-2 Pulse 5a in 12 V systems | Select only if board height allows SMA and surge severity is limited to ISO 7637-2 Pulse 1/2. |
| TPSMD15H-Q | Same PPPM (600 W), identical VCL (18.5 V), but higher IRM (1 µA) and larger SMC package (2.3 mm height) | Higher leakage increases standby power; larger footprint reduces routing density in compact modules | Prefer only when existing SMC land pattern is fixed and thermal mass requirements exceed SOD128 capability. |
Compared with SMAJ15A-Q and TPSMD15H-Q, PTVS15VP1UP-QX delivers optimal balance of low profile (1 mm), ultra-low leakage (0.001 µA), and full 600 W automotive surge immunity-making it the preferred choice for next-generation space- and power-constrained vehicle ECUs.

FAQ
What is the maximum clamping voltage of PTVS15VP1UP-QX under a 10/1000 µs surge?
The maximum clamping voltage (VCL) is 18.5 V at 24.4 A peak pulse current (IPPM), measured per IEC 61643-321. This value is guaranteed across the full operating temperature range (−55 °C to +150 °C) and defines the highest voltage seen by downstream circuitry during worst-case transients.
Does PTVS15VP1UP-QX meet automotive qualification standards?
Yes, PTVS15VP1UP-QX is fully qualified to AEC-Q101 for stress testing of discrete semiconductors, including temperature cycling, high-temperature operating life, and ESD (30 kV contact/air discharge). It is explicitly recommended for automotive applications in Nexperia's official product documentation.
How does the SOD128 package affect thermal performance compared to SMA or SMC?
The SOD128 package achieves Rth(j-sp) = 12 K/W-significantly lower than SMA (≈40 K/W) and competitive with SMC (≈15 K/W)-due to its wide cathode tab and optimized thermal path to PCB copper. This enables higher surge repetition rates without junction overheating when using a 1 cm² thermal pad.
Can PTVS15VP1UP-QX be used in bidirectional configurations?
No, PTVS15VP1UP-QX is strictly unidirectional. Its anode-cathode structure conducts only during positive transients on the cathode side. For bidirectional protection (e.g., data lines), two devices in series opposition or a dedicated bidirectional TVS like PTVS15VB1UP-QX must be used.
