Product details
Overview
PTVS22VP1UP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for automotive-grade overvoltage protection at 22 V reverse standoff voltage. It delivers 35.5 A peak pulse current (10/1000 µs), clamps transients to ≤35.5 V, and exhibits ≤0.001 µA reverse leakage at VRWM - deployed in engine control units and infotainment power rails.
For engineers reviewing the PTVS22VP1UP-QX datasheet, PTVS22VP1UP-QX pinout, PTVS22VP1UP-QX application, or PTVS22VP1UP-QX equivalent, key selection criteria include clamping voltage (VCL = 35.5 V), AEC-Q101 qualification, 1 mm profile for space-constrained PCB layouts, and thermal resistance to solder point (Rth(j-sp) = 12 K/W).
Technical Context
This TVS diode operates as a unidirectional clamping device, triggered when reverse voltage exceeds VRWM = 22 V and entering avalanche breakdown at VBR = 24.4–26.9 V (min–max). Its response is defined by IEC 61643-321 10/1000 µs waveform compliance and supports single-pulse surge handling up to 600 W.
Thermal design relies on low-profile SOD128 mounting: Rth(j-a) = 200 K/W (FR4, standard footprint), but drops to 12 K/W to cathode solder point - enabling effective heat dissipation in high-density automotive modules without heatsinks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W - sustains 10/1000 µs surges per IEC 61643-321 without degradation |
| Reverse Standoff Voltage (VRWM) | 22 V - maximum continuous DC or RMS voltage before significant leakage begins |
| Clamping Voltage (VCL) | 35.5 V @ IPPM = 35.5 A - limits transient voltage seen by protected ICs during surge events |
| Breakdown Voltage (VBR) | 24.4–26.9 V @ IR = 1 mA - defines precise avalanche onset range for predictable triggering |
| Reverse Leakage (IRM) | ≤0.001 µA @ VRWM - negligible standby current impact on low-power 22 V systems |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact/air) - robust immunity against human-body and system-level ESD events |
| Package | SOD128 (CFP5) - 3.8 × 2.6 × 1.0 mm surface-mount outline with cathode marking bar |
Pinout & Package
SOD128 (CFP5) plastic surface-mounted package: 2-terminal, flat lead, 4 mm pitch, 1 mm height, tin-plated terminations. Cathode identified by molded marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to protected circuit's positive rail; avalanche conduction occurs from anode to cathode during overvoltage |
| 2 (A) | Anode | Connected to ground or low-impedance return path; completes clamping loop during transient events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood and cabin applications per stress test requirements |
| 1 mm package height | Enables placement beneath connectors or near tall components in compact ECUs |
| Low thermal resistance to solder point | Rth(j-sp) = 12 K/W - allows efficient heat transfer directly into PCB copper via cathode tab |
| High ESD immunity | ±30 kV contact/air discharge - eliminates need for additional ESD protection stages |
| Stable clamping across temperature | VCL variation < ±5 % from −40 °C to +125 °C - ensures consistent protection in wide ambient ranges |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Infotainment Display Supply |
|---|---|
Use Scenario: 12 V battery line exposed to load dump (up to 35 V) and alternator ripple in gasoline/diesel powertrains. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input fuse and DC-DC converter input. Use Value: Clamps transients to 35.5 V within nanoseconds, preventing damage to 36 V-rated buck controllers and preserving ASIL-B functional safety integrity. |
Use Scenario: 5 V/12 V display backlight and interface power rails subject to hot-swap and cable ESD in center-stack displays. IC Role / Device Role / Timing Role: Primary surge clamp on power entry before LDOs and level shifters. Use Value: Sub-1 µA leakage avoids quiescent current penalties; 30 kV ESD rating protects against repeated connector mating cycles. |
| ADAS Camera Module Power Rail | Body Control Module (BCM) LIN Bus Protection |
Use Scenario: 3.3 V or 5 V imaging sensor supply lines vulnerable to inductive kickback from nearby solenoid drivers. IC Role / Device Role / Timing Role: Localized TVS adjacent to image sensor PMIC input. Use Value: 1 mm height fits under camera lens housing; 35.5 A peak current handles worst-case coupled surges without derating. |
Use Scenario: LIN bus transceiver VBAT supply line subjected to ISO 7637-2 pulses (Pulse 1/2a/5a) in door modules and seat controls. IC Role / Device Role / Timing Role: Secondary protection stage after primary LC filter, before transceiver VCC pin. Use Value: 22 V VRWM aligns with LIN VBAT nominal (12 V ±10 % + transients); clamping margin preserves transceiver's 36 V absolute max rating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A-Q | 400 W PPPM, SMA package (2.4 mm height), VCL = 35.5 V @ 32.4 A | Larger footprint and height; lower surge rating reduces margin in high-energy load dump scenarios | Select when board space permits larger package and 400 W rating suffices for ISO 7637-2 Pulse 5a compliance |
| TPSMD22A | 3000 W PPPM, DO-214AB package (2.6 mm height), VCL = 35.5 V @ 84.5 A | Higher surge capacity but 2.6× taller; not AEC-Q101 qualified out-of-box | Choose only if legacy designs require DO-214AB footprint and AEC validation is handled separately |
Compared with SMAJ22A-Q and TPSMD22A, PTVS22VP1UP-QX uniquely balances AEC-Q101 compliance, ultra-low 1 mm profile, and 600 W surge capability - making it optimal for next-gen automotive modules where height, reliability, and energy absorption are jointly constrained.

FAQ
What is the maximum clamping voltage of PTVS22VP1UP-QX under rated surge conditions?
The clamping voltage (VCL) is 35.5 V at peak pulse current (IPPM) of 35.5 A, measured per IEC 61643-321 10/1000 µs waveform. This value is guaranteed across the full operating junction temperature range (−40 °C to +150 °C) and defines the upper voltage limit imposed on protected circuitry during surge events.
Is PTVS22VP1UP-QX suitable for bidirectional transient protection?
No - PTVS22VP1UP-QX is a unidirectional TVS diode, configured for protection against positive-going transients on grounded systems. It conducts only when anode-to-cathode voltage exceeds breakdown; for bidirectional (AC-line or floating-rail) protection, a dedicated bidirectional variant like PTVS22VB1UP-QX is required.
How does the SOD128 package affect thermal performance in high-reliability automotive layouts?
The SOD128 package enables direct thermal coupling from junction to cathode solder pad, achieving Rth(j-sp) = 12 K/W. When mounted on 1 cm² copper pour per Nexperia's layout recommendation, this allows sustained 600 W pulse dissipation without exceeding 150 °C junction temperature - critical for under-hood modules operating at 125 °C ambient.
Does PTVS22VP1UP-QX require external current-limiting components in series?
No - unlike Zener-based protectors, this TVS diode self-limits current during clamping and requires no series resistor. Its low dynamic impedance (< 0.3 Ω) ensures rapid voltage stabilization; however, system-level fusing remains necessary upstream to clear catastrophic short-circuit faults per ISO 16750-2.
