Product details
Overview
D3V3AP2WF-7 from Diodes Incorporated is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for ESD and surge protection at battery contacts and power rails. It features a 3.3V reverse standoff voltage, 5.2V minimum breakdown voltage at 10mA, 8.0V maximum clamping voltage at 28.2A peak pulse current, and 225W peak pulse power (10/1000µs), making it suitable for portable electronics power management interfaces.
For engineers reviewing the D3V3AP2WF-7 datasheet, D3V3AP2WF-7 pinout, D3V3AP2WF-7 application, or D3V3AP2WF-7 equivalent, key selection criteria include clamping performance under IEC 61000-4-2 ±30kV contact/air discharge, thermal resistance (RθJA = 330°C/W), SOD123F package compatibility, and DC power dissipation limit of 1.0W at +25°C.
Technical Context
This TVS operates in avalanche breakdown mode to clamp transient overvoltages before they damage downstream circuitry. Its unidirectional configuration provides protection only against negative transients relative to cathode, with cathode marked by a bar on the SOD123F package body.
The device meets IEC 61000-4-2 Level 4 ESD immunity (±30kV air, ±30kV contact) and delivers stable clamping up to 28.2A peak pulse current under standardized 10/1000µs waveform, while maintaining low leakage (<1000µA at 3.3V) and low capacitance (~3.5pF at 0V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage (VRWM) | 3.3V - Maximum continuous DC voltage the device blocks without significant leakage. |
| Breakdown Voltage (VBR min) | 5.2V @ 10mA - Voltage at which avalanche conduction begins; defines turn-on threshold for transient suppression. |
| Clamping Voltage (VC max) | 8.0V @ 28.2A - Maximum voltage seen by protected circuit during worst-case 10/1000µs surge. |
| Peak Pulse Power (PPK) | 225W (10/1000µs) - Surge energy handling capacity; determines survivability of common lightning/ESD events. |
| ESD Rating | ±30kV contact & air (IEC 61000-4-2) - Confirmed immunity level for handheld and battery-connected devices. |
| Thermal Resistance (RθJA) | 330°C/W - Limits steady-state power dissipation to 1.0W on standard FR-4 PCB; guides heatsinking requirements. |
| Package | SOD123F - Compact 2-pin surface-mount outline (2.7mm × 1.8mm × 1.15mm); compatible with automated assembly. |
Pinout & Package
SOD123F is a two-terminal surface-mount package with cathode identified by a molded bar on the top surface. Anode and cathode leads are formed from copper alloy with matte tin finish, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path | Connected to ground or low-impedance reference; completes clamping loop during overvoltage event. |
| Cathode | Protected line connection | Connected to power rail or signal line needing protection; marked by bar; carries surge current into anode. |
Key Features
| Feature | Design Value |
|---|---|
| IEC 61000-4-2 ESD robustness | ±30kV contact/air - Eliminates need for external ESD staging in consumer battery interfaces. |
| Low clamping ratio (VC/VBR) | 8.0V / 5.2V ≈ 1.54 - Tight voltage margin ensures protected ICs remain within absolute maximum ratings during surge. |
| Halogen- and antimony-free construction | <900ppm Br, <900ppm Cl, <1000ppm Sb - Meets global environmental compliance (RoHS 3, JEDEC J-STD-020 Level 1). |
| Steady-state power capability | 1.0W at +25°C - Supports continuous operation in low-duty-cycle power management nodes with minimal derating. |
Applications
| Smartphone Battery Interface | USB-C Power Delivery Port |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ3.3A | Higher RθJA (440°C/W), larger SMA package (4.5×2.7mm), 400W PPK rating | Better surge handling but requires 3× PCB area; less suitable for ultra-compact battery contacts | Select when peak current exceeds 28.2A or board layout allows larger footprint. |
| DF2S7.0FL | Lower VC (6.5V), lower PPK (150W), smaller SOD-923 (1.0×0.6mm), 12pF capacitance | Superior clamping but higher capacitance limits use in high-speed data lines; not rated for ±30kV contact ESD | Select for space-constrained signal-line protection where ESD severity is ≤±15kV. |
Compared with SMAJ3.3A and DF2S7.0FL, D3V3AP2WF-7 uniquely balances ultra-compact SOD123F size, ±30kV ESD immunity, and 8.0V clamping-making it optimal for battery terminal protection where board space and reliability are co-constrained.

FAQ
What is the polarity configuration of D3V3AP2WF-7?
D3V3AP2WF-7 is a unidirectional TVS diode with cathode marked by a bar on the SOD123F package. It conducts only when the cathode is driven positive relative to the anode, making it suitable for protecting positive power rails against negative-going transients. The device does not conduct under normal 3.3V DC bias, exhibiting <1000µA leakage at VRWM.
Can D3V3AP2WF-7 be used in automotive applications?
D3V3AP2WF-7 is not AEC-Q200 qualified and lacks PPAP documentation or IATF 16949-certified manufacturing evidence in its public datasheet. While its operating temperature range (−55°C to +150°C) meets automotive ambient requirements, Diodes Incorporated explicitly states that automotive-grade variants require direct consultation and custom qualification-this part is specified for commercial use only.
How does the SOD123F package affect thermal performance?
The SOD123F package delivers RθJA = 330°C/W on a 1"×1" FR-4 board with 2 oz. copper, limiting steady-state power dissipation to 1.0W at +25°C. Its low mass (0.018g) and exposed cathode tab enable rapid thermal response to short pulses, but sustained power must be strictly limited to avoid junction temperature exceeding 150°C-derating curves show 50% power reduction at +100°C ambient.
Is D3V3AP2WF-7 compatible with lead-free reflow processes?
Yes-D3V3AP2WF-7 features a matte tin finish over copper alloy leadframe and is rated for lead-free reflow per JEDEC J-STD-020. Its moisture sensitivity level is MSL 1 (unlimited floor life at ≤30°C/60% RH), eliminating bake requirements prior to assembly. The package uses halogen-free molding compound compliant with UL 94V-0 flammability rating.
