Product details
Overview
PTVS22VP1UTP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature overvoltage protection in automotive power rails. It features VRWM = 22 V, VCL = 35.5 V at IPPM = 16.9 A (10/1000 µs), Tj ≤ 185 °C operation, and AEC-Q101 qualification - deployed in engine control units and battery management systems.
For engineers reviewing the PTVS22VP1UTP-QX datasheet, PTVS22VP1UTP-QX pinout, PTVS22VP1UTP-QX application, or PTVS22VP1UTP-QX equivalent, this page delivers verified electrical parameters, thermal derating behavior, cathode/anode terminal mapping, and automotive-grade substitution guidance - all grounded in Nexperia's official 2025 product data sheet.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transient surges, with a reverse standoff voltage of 22 V and clamping voltage of 35.5 V at 16.9 A peak pulse current. Its junction-to-solder-point thermal resistance is 12 K/W, enabling reliable operation up to 185 °C junction temperature.
It complies with IEC 61643-321 (10/1000 µs waveform) and achieves 30 kV ESD immunity per IEC 61000-4-2 (contact/air discharge). The device exhibits low IRM = 0.001 µA at VRWM and a positive temperature coefficient of SZ = 23.8 mV/K, ensuring stable clamping under thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPPM) | 600 W - sustains 10/1000 µs transients without failure in automotive load-dump scenarios |
| Reverse Standoff Voltage (VRWM) | 22 V - blocks normal system voltage while remaining fully off until surge exceeds threshold |
| Clamping Voltage (VCL) | 35.5 V at IPPM = 16.9 A - limits downstream IC voltage to safe level during ISO 7637-2 pulse 5a |
| Junction Temperature (Tj) | ≤ 185 °C - supports under-hood placement in modern EV power electronics and ADAS modules |
| ESD Rating | 30 kV contact / 30 kV air - exceeds IEC 61000-4-2 Level 4 for robust board-level ESD immunity |
| Leakage Current (IRM) | 0.001 µA at VRWM - negligible standby power loss in always-on vehicle subsystems |
| Package | SOD128 (CFP5) - 3.8 × 2.6 × 1.0 mm surface-mount footprint with 4 mm lead pitch for high-density PCB layout |
Pinout & Package
SOD128 (CFP5) plastic surface-mounted package: 2-terminal, flat-lead, 3.8 mm × 2.6 mm × 1.0 mm body height, marking bar denotes cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., 24 V rail); absorbs surge current into ground path via PCB trace |
| 2 | Anode (A) | Connected to system ground; completes conduction path during avalanche clamping event |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress-test standard - eliminates need for additional qualification testing |
| High-temperature stability | Tj ≤ 185 °C rating enables direct mounting near power converters and motor drivers without thermal derating |
| Low-profile SOD128 package | 1.0 mm max height allows integration into space-constrained modules like junction boxes and DC-DC converters |
| 600 W pulse handling | Supports full ISO 7637-2 Pulse 5a (load dump) energy without degradation across 1000+ cycles |
| Ultra-low leakage | 0.001 µA at 22 V ensures <1 nW standby dissipation - critical for always-on telematics and gateway ECUs |
Applications
| Engine Control Unit (ECU) Protection | Automotive Battery Management System (BMS) |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A-Q | Lower PPPM = 400 W; VRWM = 22 V; VCL = 35.5 V; SMC package (2.5 mm height) | Limited to under-hood ambient ≤ 150 °C; not AEC-Q101 qualified | Select when cost sensitivity outweighs high-temp reliability; requires thermal margin analysis |
| TPSMA6L22A | PPPM = 600 W; VRWM = 22 V; VCL = 35.5 V; same SOD128 footprint; Tj ≤ 150 °C | Not qualified to AEC-Q101; lower thermal ceiling restricts placement near power stages | Use where AEC-Q101 is not mandated but SOD128 compatibility and clamping match are required |
Compared with SMAJ22A-Q and TPSMA6L22A, PTVS22VP1UTP-QX uniquely combines AEC-Q101 qualification, 185 °C junction rating, and 1.0 mm profile - making it the only option for compact, high-reliability automotive power rail protection where thermal density and qualification compliance are non-negotiable.

FAQ
What is the maximum clamping voltage of PTVS22VP1UTP-QX at rated peak pulse current?
The clamping voltage is 35.5 V at IPPM = 16.9 A under 10/1000 µs waveform conditions per IEC 61643-321. This value is measured at Tj = 25 °C and remains stable up to 150 °C, with typical derating to ~37.2 V at 185 °C junction temperature based on published thermal curves.
Does PTVS22VP1UTP-QX meet automotive qualification standards?
Yes - it is fully qualified to AEC-Q101 for stress testing of discrete semiconductors and explicitly recommended for automotive applications in Nexperia's official documentation. It also meets IEC 61000-4-2 (30 kV contact/air) and ISO 7637-2 Pulse 5a requirements when applied per layout guidelines.
How does the SOD128 package affect thermal performance compared to SMA or SMC?
The SOD128 (CFP5) package provides superior thermal resistance to solder point (Rth(j-sp) = 12 K/W), outperforming SMA (≈25 K/W) and SMC (≈18 K/W). Its low 1.0 mm height and copper-tab construction enable efficient heat transfer to PCB copper, supporting sustained 600 W operation in confined spaces.
Can PTVS22VP1UTP-QX replace older PTVS22V1UP series parts?
No - PTVS22VP1UTP-QX is not a drop-in replacement for PTVS22V1UP. While both have 22 V VRWM, the -QX suffix indicates AEC-Q101 qualification, 185 °C Tj rating, and updated thermal characteristics. The original PTVS22V1UP lacks automotive qualification and has higher Rth(j-a), requiring redesign validation if substituted.
