Product details
Overview
DFLT6V0A-7 from Diodes Incorporated is a unidirectional transient voltage suppressor (TVS) diode in PowerDI123 package, designed for primary overvoltage protection on DC power rails and signal lines. It features 6.0 V reverse standoff voltage, 10.3 V max clamping voltage at 21.8 A peak pulse current, and 225 W peak pulse power dissipation (10/1000 µs waveform), deployed in automotive infotainment power inputs.
For engineers reviewing the DFLT6V0A-7 datasheet, DFLT6V0A-7 pinout, DFLT6V0A-7 application, or DFLT6V0A-7 equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, IPP capability under ISO 7637-2 pulse 5a, thermal resistance (RθJS = 6 °C/W), and AEC-Q101 qualification status for automotive use.
Technical Context
This TVS operates as a clamping device: when reverse voltage exceeds 6.0 V standoff, it avalanches at minimum 6.67 V (VBR) with 10 mA test current, limiting transients to ≤10.3 V at 21.8 A. Its low RθJS of 6 °C/W enables effective heat transfer from junction to PCB cathode tab under surge conditions.
The PowerDI123 package uses a single-cathode-band terminal configuration with matte tin–annealed copper leadframe. It delivers 1.0 W DC power dissipation on FR-4 with 1-inch² 2 oz copper pad, and supports moisture sensitivity level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 6.0 V - Maximum continuous DC operating voltage before avalanche conduction begins. |
| Breakdown Voltage (min) | 6.67 V @ 10 mA - Ensures reliable triggering above system nominal rail without false clamping. |
| Max Clamping Voltage | 10.3 V @ 21.8 A - Limits transient overshoot to safe levels for 5 V logic and microcontroller I/O. |
| Peak Pulse Power | 225 W (10/1000 µs) - Withstands automotive load dump and ISO 7637-2 pulse 5a surges. |
| Thermal Resistance (J-to-S) | 6 °C/W - Enables rapid heat sinking to PCB cathode pad, critical for repeated surge endurance. |
| DC Power Dissipation | 1.0 W - Defines steady-state thermal limit on standard FR-4 layout with 1-inch² copper area. |
Pinout & Package
Package: PowerDI123 - surface-mount, single-row, 2-terminal molded plastic package with exposed cathode tab for thermal and electrical connection. Dimensions: 1.78 mm × 3.70 mm × 1.00 mm (L × W × H); weight ≈ 0.01 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point during clamping | Connected to protected line (e.g., +5 V rail); carries full surge current into diode junction. |
| Cathode (band-marked) | Transient current return path and thermal interface | Connected to ground plane; serves as primary thermal conduction path to PCB copper via exposed metal tab. |
Key Features
| Feature | Design Value |
|---|---|
| 225 W peak pulse power (10/1000 µs) | Meets ISO 7637-2 Pulse 5a requirements for 12 V automotive systems without derating. |
| Low clamping ratio (VC/VRWM = 1.72) | Minimizes voltage overshoot margin needed for downstream 5 V ICs, reducing design headroom risk. |
| RθJS = 6 °C/W | Enables >90% of surge energy to dissipate directly into PCB ground plane, improving reliability vs. higher-RθJS SOD-123 devices. |
| AEC-Q101 qualified variant available (DFLT6V0AQ) | Supports automotive production programs requiring PPAP documentation and IATF 16949 traceability. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Protection |
|---|---|

Use Scenario: Shields 24 V digital input optocoupler front-end from field-wiring induced surges in factory automation cabinets. IC Role / Device Role: Primary overvoltage clamp on input side of series resistor/opto pair. Use Value: Low RθJS allows sustained surge handling without thermal runaway, supporting EN 61000-4-5 Level 4 compliance. |
| USB-C Power Delivery Port | Automotive Infotainment Display Interface |
Use Scenario: Guards VBUS line in USB-C PD sink applications against hot-plug and ESD-induced overshoot. IC Role / Device Role: Secondary clamping device downstream of primary ESD array, targeting fast-rising transients. Use Value: 10.3 V clamping ensures PD controller ICs (e.g., FUSB302) remain within 12 V absolute max rating during 100 ns edge surges. |
Use Scenario: Protects LVDS or FPD-Link III video data lines from ESD and cable discharge events in head unit displays. IC Role / Device Role: Low-capacitance TVS (CT < 100 pF at 0 V) placed inline on differential pairs. Use Value: Measured capacitance < 70 pF at 0 V preserves signal integrity up to 1.5 Gbps without eye diagram degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A (onsemi) | Same 6.0 V VRWM, but SMA package (RθJA = 150 °C/W vs. 125 °C/W); 200 W PPK; no AEC-Q101 variant. | Larger footprint; lower surge robustness due to higher thermal resistance; not automotive-qualified. | Select only for cost-sensitive industrial designs where PCB space and thermal performance are secondary. |
| DFLT6V0AQ (Diodes) | Identical electrical specs; AEC-Q101 qualified; manufactured in IATF 16949 facility; PPAP-capable. | Required for Tier 1 automotive production; supports change control and lot traceability. | Choose for automotive programs needing formal qualification and supply chain compliance. |
Compared with SMAJ6.0A, DFLT6V0A-7 offers superior thermal performance and smaller footprint; compared with DFLT6V0AQ, it lacks automotive qualification but shares identical clamping behavior and surge ratings-making it suitable for pre-qualification prototyping or non-automotive volume production.

FAQ
What is the maximum operating temperature for DFLT6V0A-7?
The DFLT6V0A-7 has an operating junction temperature range of –65 °C to +150 °C. Its thermal resistance from junction to soldering point is 6 °C/W, enabling reliable operation at full rated surge current when mounted on a 1-inch² 2 oz copper pad per Diodes' recommended layout.
Is DFLT6V0A-7 RoHS and halogen-free compliant?
Yes. DFLT6V0A-7 features a lead-free matte tin finish over copper leadframe and uses a halogen- and antimony-free "Green" molding compound meeting RoHS 3 (2015/863/EU) with Br+Cl <1500 ppm and Sb <1000 ppm, certified per Diodes' quality definitions.
Does DFLT6V0A-7 meet AEC-Q101 requirements?
No - DFLT6V0A-7 is the commercial-grade version. The automotive-qualified variant is DFLT6V0AQ, which undergoes AEC-Q101 stress testing, is produced in IATF 16949-certified facilities, and supports PPAP documentation for automotive programs.
How does the PowerDI123 package improve thermal performance over SOD-123?
PowerDI123's exposed cathode tab provides direct thermal conduction to the PCB ground plane, achieving RθJS = 6 °C/W versus ~100 °C/W for standard SOD-123. This reduces junction temperature rise by >80% under 21.8 A surge, significantly extending device lifetime in repetitive transient environments.
