Product details
Overview
PTVS30VP1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at 30 V reverse standoff voltage (VRWM), with clamping voltage VCL = 48.4 V at IPPM = 12.4 A and IRM ≤ 0.001 µA. It features AEC-Q101 qualification, 1 mm profile, and IEC 61643-321 (10/1000 µs) compliance for robust ESD and surge immunity in power rails.
For engineers reviewing the PTVS30VP1UP-QX datasheet, PTVS30VP1UP-QX pinout, PTVS30VP1UP-QX application, or PTVS30VP1UP-QX equivalent, this device is selected for high-reliability 30 V DC power line protection where low leakage, tight clamping, automotive qualification, and surface-mount compatibility are critical design requirements.
Technical Context
This TVS diode operates as a unidirectional clamping device-forward-biased during positive transients on the cathode side-leveraging silicon avalanche breakdown to limit voltage excursions. Its 30 V VRWM ensures stable blocking under nominal 24 V automotive systems with margin, while VBR = 33.3–36.8 V (min–max) defines the onset of conduction.
Thermal performance is defined by Rth(j-sp) = 12 K/W to solder point and derating curves showing PPPM retention ≥80% up to Tj = 125 °C. The 10/1000 µs waveform compliance confirms suitability for ISO 7637-2 pulse 1, 2a, 3a/b, and IEC 61000-4-5 surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 30 V - Maximum continuous reverse operating voltage before leakage exceeds 0.1 µA; sets safe operating margin above 24 V nominal rail. |
| VCL @ IPPM | 48.4 V at 12.4 A - Clamped voltage during 10/1000 µs surge; limits downstream IC stress to sub-50 V during worst-case transients. |
| PPPM | 600 W - Peak pulse power handling per IEC 61643-321; supports high-energy surges without thermal runaway. |
| IRM | ≤ 0.001 µA @ VRWM - Ultra-low reverse leakage preserves battery life and minimizes standby power loss in always-on modules. |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - Full-system ESD immunity without external staging components. |
| Package | SOD128 (CFP5) - 3.8 × 2.6 × 1.0 mm footprint with 4 mm lead pitch; optimized for automated placement and high-density PCB layouts. |
| AEC-Q101 | Qualified - Validated for automotive under temperature cycling, HTRB, HTGB, and ESD stress; supports ASIL-B system integration. |
Pinout & Package
SOD128 (CFP5) plastic surface-mount package: 2-terminal, flat lead, 1 mm height, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected line (e.g., 24 V rail); absorbs positive transients when voltage exceeds VBR. |
| 2 (A) | Anode | Connected to ground reference; completes clamping path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q101 certified - Enables direct use in engine control units, body electronics, and ADAS power domains without requalification. |
| Low-profile packaging | 1.0 mm max height - Allows placement beneath connectors or in constrained under-hood space without mechanical interference. |
| Tight clamping ratio | VCL/VRWM = 1.61 - Minimizes overvoltage headroom, reducing stress on downstream 40 V-rated DC-DC converters and microcontrollers. |
| High surge current capability | IPPM = 12.4 A - Handles repetitive load dump pulses (ISO 7637-2 Pulse 5a) without parameter shift or degradation. |
| Ultra-low leakage | IRM ≤ 0.001 µA - Eliminates measurable current drain in 12 V/24 V battery-backed circuits over 10+ year service life. |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Infotainment Power Rail |
|---|---|
|
Use Scenario: Protection of 24 V supply input to engine control module against load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed directly at connector entry point to shunt surge energy to chassis ground. Use Value: Limits transient voltage to ≤48.4 V, preventing latch-up or damage to 40 V-rated LDOs and CAN transceivers downstream. |
Use Scenario: Guarding 12 V/24 V power feed to infotainment head unit against jump-start spikes and ESD coupling via USB/HDMI ports. IC Role / Device Role / Timing Role: Primary front-end TVS on main power rail, coordinated with secondary LC filtering for broadband suppression. Use Value: Withstands ±30 kV ESD and 600 W surges while maintaining <1 µA leakage-critical for low-power sleep modes and battery runtime. |
| ADAS Camera Module Supply | Body Control Module (BCM) Sensor Interface |
|
Use Scenario: Protecting 5 V or 3.3 V internal supply derived from 12 V via buck converter in rear-view camera module exposed to harness-induced transients. IC Role / Device Role / Timing Role: Secondary-stage TVS on regulated output rail, triggered only after primary 24 V rail clamping. Use Value: Clamps residual overshoot to <50 V within nanoseconds, ensuring image sensor and serializer ICs remain within absolute maximum ratings. |
Use Scenario: Safeguarding LIN bus or analog sensor inputs (e.g., ambient light, rain sensor) connected to 12 V domain in BCM. IC Role / Device Role / Timing Role: Point-of-load TVS on sensor supply line, sized for low capacitance (<100 pF) to avoid signal integrity degradation. Use Value: Provides 30 V standoff with 48.4 V clamping-compatible with 5 V ADC references and op-amp input ranges without signal distortion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A-Q | Same VRWM (30 V), but lower PPPM (400 W), higher VCL (49.3 V), and SMA package (2.5 mm height). | Lacks AEC-Q101 qualification; not approved for automotive safety-critical modules. | Select when cost sensitivity outweighs automotive qualification and height constraints are relaxed. |
| TPSMD30A | Higher VRWM tolerance (33 V), same PPPM (600 W), but larger SMC package (7.1 mm width) and no AEC-Q101 documentation. | Requires larger PCB area; unverified for automotive temperature cycling and humidity testing. | Prefer only for industrial power supplies where footprint and qualification are non-binding. |
Compared with SMAJ30A-Q and TPSMD30A, PTVS30VP1UP-QX delivers superior automotive readiness (AEC-Q101), minimal 1 mm height for space-constrained modules, and tighter clamping (48.4 V vs. ≥49.3 V), making it the optimal choice for next-gen ECU, ADAS, and infotainment power protection.

FAQ
What is the maximum junction temperature rating for PTVS30VP1UP-QX?
The absolute maximum junction temperature (Tj) is 150 °C per IEC 60134 limiting values. Derating begins above 25 °C ambient, with rated peak pulse power dropping to ~80% at Tj = 125 °C, as shown in Figure 2 of the datasheet. This enables operation in under-hood environments with proper PCB copper area.
Does PTVS30VP1UP-QX support bidirectional transient suppression?
No-it is a unidirectional TVS diode, configured to clamp only positive transients on the cathode terminal relative to anode (ground). For bidirectional protection (e.g., data lines), a separate symmetric device like PTVS30VS1UP-QX is required; mixing unidirectional types risks failure during negative surges.
How does the SOD128 package affect thermal performance compared to SMA or SMC?
The SOD128's low 12 K/W junction-to-solder-point thermal resistance (Rth(j-sp)) enables faster heat dissipation into PCB copper than SMA (Rth(j-a) ≈ 60 K/W) or SMC (Rth(j-a) ≈ 40 K/W). This allows sustained 600 W pulse handling in compact layouts without thermal throttling or derating penalties.
Can PTVS30VP1UP-QX replace older P6SMB30A in automotive designs?
Yes-but only after validation: PTVS30VP1UP-QX offers identical VRWM (30 V) and improved specs (lower VCL, AEC-Q101, 1 mm height), yet differs in package (SOD128 vs. DO-214AA) and pinout (cathode/anode orientation). PCB footprint and solder stencil must be updated; electrical behavior is superior in all key metrics.
