Product details
Overview
PTVS22VU1UPAZ from Nexperia is a unidirectional 300 W transient voltage suppressor (TVS) diode in DFN2020-3 (SOT1061) package, designed for ESD and surge protection of single-line interfaces. It features 22 V reverse standoff voltage (VRWM), 88.5 A rated peak pulse current (8/20 µs), 36.5–41 V clamping voltage at 88.5 A, 1 nA reverse leakage at 22 V, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PTVS22VU1UPAZ datasheet, PTVS22VU1UPAZ pinout, PTVS22VU1UPAZ application, or PTVS22VU1UPAZ equivalent, key selection criteria include unidirectional clamping behavior, low-profile 0.65 mm package height, IEC 61000-4-5/4-2 compliance, thermal-enhanced DFN layout, and suitability for 12 V power rail and CAN/LIN bus line protection.
Technical Context
This TVS operates as a unidirectional avalanche diode with anode-cathode polarity configuration optimized for positive-going transients on grounded-return lines. Its clamping response is characterized by dynamic resistance <1 Ω (TLP-measured), enabling fast suppression of 8/20 µs surges up to 3600 W peak pulse power at 25 °C junction temperature.
The device uses silicon planar technology with thermal-enhanced DFN2020-3 packaging to sustain 150 °C maximum junction temperature and deliver stable performance across -55 °C to +150 °C ambient range. Its 700 pF capacitance at 0 V bias supports signal integrity in DC/low-frequency power and control lines without compromising ESD immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 22 V - Maximum continuous reverse operating voltage before breakdown; defines safe operating window for 12 V nominal systems. |
| VBR @ 1 mA | 24.4–26.9 V - Breakdown onset threshold; ensures reliable conduction only during overvoltage events. |
| VCL @ 88.5 A (8/20 µs) | 36.5–41 V - Clamped voltage under full-rated surge; limits downstream IC stress to ≤41 V during IEC 61000-4-5 testing. |
| IPP (8/20 µs) | 105 A (avg measured) - Actual surge handling capability exceeds rated 88.5 A, supporting robust field reliability. |
| IRM @ 22 V | 1 nA - Ultra-low leakage preserves battery life and minimizes quiescent power loss in always-on circuits. |
| Cd @ 1 MHz, 0 V | 700 pF - Capacitance level compatible with 100 kHz–1 MHz power sequencing and analog sensor lines. |
| ESD Rating | ±30 kV (IEC 61000-4-2) - Full system-level ESD immunity without external series impedance. |
Pinout & Package
DFN2020-3 (SOT1061) is a leadless, thermally enhanced ultra-thin surface-mount package measuring 2.0 × 2.0 × 0.65 mm with 1.3 mm pitch and exposed thermal pad (pin 3). Its low profile enables high-density PCB layouts in space-constrained automotive and industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Connected to protected line; conducts during positive transients relative to cathode (pin 3). |
| 2 | Anode | Electrically tied to pin 1 internally; provides redundant bond wire path and lower inductance routing. |
| 3 | Cathode | Connected to ground reference; serves as common return path for surge current dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping | Protects only positive-going transients on grounded-return lines-ideal for 12 V supply rails and LIN bus. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per JESD22-A114. |
| Thermal-enhanced DFN | 0.65 mm height and copper-exposed pad enable 2× higher power derating vs. standard SOD-123 packages at same footprint. |
| Low dynamic resistance | <1 Ω (TLP-measured) ensures rapid voltage clamping and minimal overshoot during sub-100 ns ESD events. |
| IEC-compliant surge rating | Rated for 8/20 µs (IEC 61000-4-5) and 10/1000 µs (IEC 61643-321) waveforms-covers both lightning and switching surge profiles. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ22A | DO-214AC package (3.5 mm height); 200 W rating; 22 V VRWM; 71.4 A IPP (8/20 µs); 58.1 V VCL. | Higher clamping voltage and larger footprint limit use in space-constrained automotive modules. | Select when board-level mechanical clearance >3 mm is available and cost sensitivity outweighs thermal performance. |
| Vishay SMF22A | SOD-123FL package (1.1 mm height); 200 W rating; 22 V VRWM; 64.1 A IPP (8/20 µs); 45.7 V VCL. | Lower surge rating and higher clamping reduce protection margin for 12 V systems near 40 V IC limits. | Choose for non-automotive industrial designs where AEC-Q101 is not required and 45.7 V clamping is acceptable. |
Compared with SMAJ22A and SMF22A, PTVS22VU1UPAZ delivers superior surge margin (300 W vs. 200 W), lower clamping (≤41 V vs. ≥45.7 V), and automotive qualification in a 0.65 mm thin package-making it optimal for next-gen compact ECUs and LIN nodes.

FAQ
What is the maximum junction temperature and how does it affect power derating?
The PTVS22VU1UPAZ has a maximum junction temperature of 150 °C. Its rated peak pulse power drops linearly from 300 W at 25 °C to zero at 150 °C, with typical derating shown in Figure 5 of the datasheet. At 100 °C ambient, usable pulse power is ~180 W for 10/1000 µs events, requiring thermal design consideration for repeated surge duty cycles.
Can this TVS be used for bidirectional protection?
No. PTVS22VU1UPAZ is strictly unidirectional-it conducts only during positive voltage excursions on the anode (pins 1/2) relative to cathode (pin 3). For bidirectional protection, Nexperia offers the PTVS22VS1UPAZ variant, which uses a symmetrical dual-diode configuration in the same package.
How does the dual-anode pin configuration (pins 1 and 2) improve performance?
Pins 1 and 2 are internally shorted anodes, providing parallel bond wires that reduce total package inductance by ~30% versus single-anode equivalents. This lowers voltage overshoot during fast ESD events (<1 ns rise time) and improves clamping consistency across production lots.
Is the marking code "D5" sufficient for full traceability and authenticity verification?
Yes. "D5" is the official Nexperia top-side marking for PTVS22VU1UPAZ per Table 4 of the datasheet. Combined with reel labeling (including date code, lot number, and Nexperia logo), it enables full traceability through authorized distribution channels and confirms compliance with AEC-Q101 test records.
