Product details
Overview
DFLT5V0A-7 from Diodes Incorporated is a unidirectional 5.0V transient voltage suppressor (TVS) diode in PowerDI123 package, designed for primary overvoltage protection of DC power rails and I/O lines. It delivers 225W peak pulse power (10/1000µs), clamps at ≤9.2V under 24.5A peak pulse current, and exhibits ≤400µA reverse leakage at 5.0V standoff - deployed in automotive infotainment power inputs and USB-C port surge protection.
For engineers reviewing the DFLT5V0A-7 datasheet, DFLT5V0A-7 pinout, DFLT5V0A-7 application, or DFLT5V0A-7 equivalent, key selection criteria include clamping voltage margin vs. protected IC VMAX, thermal resistance to PCB copper area, standoff voltage tolerance relative to nominal rail, and AEC-Q101 qualification status for automotive use cases.
Technical Context
This TVS operates as a unidirectional avalanche diode with cathode-banded polarity, triggered when reverse voltage exceeds 6.4V (min breakdown) and fully clamping within nanoseconds. Its low RθJS of 6°C/W enables effective heat transfer from junction to solder point on FR-4 PCBs with 1-inch² 2oz copper pad.
The device sustains 50A non-repetitive forward surge (8.3ms half-sine) and maintains <3.5V forward voltage at 12A test current, supporting robust secondary surge handling in series with upstream fuses or poly-switches. Capacitance is not specified in datasheet for DFLT5V0A-7; typical values for 5V variants are <500pF at 0V bias per manufacturer characterization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRWM) | 5.0V - Maximum continuous DC operating voltage before leakage exceeds 400µA; sets upper limit for protected rail nominal voltage. |
| Breakdown Voltage (VBR) | 6.40–7.0V @ 10mA - Confirmed avalanche initiation range; ensures reliable triggering above system overvoltage thresholds. |
| Clamping Voltage (VC) | ≤9.2V @ 24.5A - Peak voltage seen by downstream circuit during 10/1000µs surge; defines minimum required IC withstand rating. |
| Peak Pulse Power (PPK) | 225W (10/1000µs) - Energy-handling capability for standard lightning/surge waveforms; derates linearly above +25°C ambient. |
| Thermal Resistance (RθJS) | 6°C/W - Junction-to-solder-point resistance; enables accurate thermal modeling when mounted on defined 2oz copper pad. |
| Package | PowerDI123 - Surface-mount, single-cathode-band, 3-pin outline (anode/cathode/tab); optimized for high-current surge path and thermal dissipation. |
Pinout & Package
DFLT5V0A-7 uses the PowerDI123 package: molded green plastic body with matte tin-plated copper leadframe, moisture sensitivity level 1, and cathode band marking on top surface. The device has two active terminals (anode and cathode) plus an exposed cathode tab serving as both electrical connection and thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode Band (Top Marking) | Reference polarity indicator | Identifies cathode terminal; must connect to higher-potential side of protected line (e.g., VIN or signal line). |
| Terminal 1 (Anode) | Anode connection | Connects to ground or return path; completes clamping loop during overvoltage events. |
| Terminal 2 (Cathode) | Cathode connection | Connects to protected node; carries full surge current during clamping; also serves as primary thermal conduction path to PCB. |
| Exposed Cathode Tab | Thermal & electrical cathode extension | Provides low-inductance, low-resistance path to PCB copper; requires solder mask opening and direct thermal pad connection for rated RθJS. |
Key Features
| Feature | Design Value |
|---|---|
| 225W peak pulse power (10/1000µs) | Supports IEC 61000-4-5 Level 4 (4kV) surge immunity on 12V automotive power rails without cascaded protection stages. |
| Low clamping voltage (≤9.2V @ 24.5A) | Enables protection of 5V logic interfaces (e.g., CAN transceivers, USB PHYs) with ≥1.8V margin below absolute maximum ratings. |
| PowerDI123 package with RθJS = 6°C/W | Allows direct thermal coupling to PCB ground plane, reducing junction temperature rise by >40% vs. SOD-123 under identical 24.5A pulses. |
| RoHS-compliant, halogen-free "Green" construction | Fulfills automotive OEM material compliance requirements (e.g., GMW3172, Ford WSS-M99P9999-A1) without sacrificing surge performance. |
Applications
| Automotive Infotainment Power Input | USB-C Port ESD/Surge Protection |
|---|---|
|
Use Scenario: 12V supply line feeding head unit MCU and display driver ICs exposed to load-dump transients up to 35V. IC Role / Device Role: Primary unilateral TVS clamp placed between fuse output and DC-DC input capacitor. Use Value: Limits transient voltage to ≤9.2V, preventing latch-up or gate oxide damage in 5V-input buck controllers and PMICs. |
Use Scenario: VBUS line of USB-C receptacle subjected to hot-plug surges and contact ESD events. IC Role / Device Role: First-line overvoltage protector upstream of USB PD controller and port power switch. Use Value: Clamps 10/1000µs surges to <9.2V while maintaining <5.0V standby leakage, avoiding false power-loss detection. |
| Industrial PLC Digital Input Protection | Smart Meter AC/DC Power Supply Clamp |
|
Use Scenario: 24V digital input channel receiving signals from field sensors with induced lightning-induced surges. IC Role / Device Role: Standoff-limited TVS paired with series current-limiting resistor to protect optocoupler input LED. Use Value: Withstands 24.5A pulses without degradation, preserving long-term reliability in outdoor metering enclosures. |
Use Scenario: Secondary-side 5V rail in switched-mode power supply powering metrology SoC and RTC. IC Role / Device Role: Final-stage clamp after bulk capacitance to suppress switching noise and residual transformer-coupled transients. Use Value: Low 3.5V forward voltage minimizes conduction loss during rare forward surges, avoiding thermal runaway in compact sealed housings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A (onsemi) | Same 5.0V standoff, but SMA package (RθJA = 150°C/W vs. DFLT5V0A-7's 125°C/W); lower 400W PPK rating (but larger footprint). | Less effective thermal coupling; requires larger copper pour for equivalent pulse handling; not AEC-Q101 qualified. | Select if legacy SMA footprint compatibility is mandatory and surge duty cycle is low. |
| DFLT5V0AQ-7 (Diodes) | AEC-Q101 qualified version with identical electrical specs; same PowerDI123 package; certified for automotive PPAP. | Required for production automotive ECUs; supports change control, IATF 16949 traceability, and extended temperature validation (-40°C to +125°C). | Choose for Tier 1 automotive designs where qualification documentation and process control are contractually mandated. |
Compared with SMAJ5.0A, DFLT5V0A-7 offers superior thermal performance in a smaller footprint and matches automotive-grade reliability when upgraded to DFLT5V0AQ-7 - making it optimal for space-constrained, thermally demanding industrial and automotive front-end protection.

FAQ
What is the maximum operating temperature for DFLT5V0A-7?
The DFLT5V0A-7 has an operating junction temperature range of –65°C to +150°C. Its thermal resistance (RθJS = 6°C/W) allows sustained operation at +125°C ambient when mounted on a 1-inch² 2oz copper pad, provided peak pulse duty cycle remains below 0.1% per IEC 61000-4-5 guidelines.
Is DFLT5V0A-7 suitable for bidirectional signal line protection?
No - DFLT5V0A-7 is a unidirectional TVS diode intended for DC power rail or single-polarity signal protection. For bidirectional applications like RS-485 or Ethernet data lines, a symmetric (bidirectional) variant such as DFLT5V0C-7 or SMAJ5.0CA must be used instead.
Does DFLT5V0A-7 meet AEC-Q101 requirements?
Standard DFLT5V0A-7 is not AEC-Q101 qualified. However, the automotive-grade variant DFLT5V0AQ-7 is fully qualified to AEC-Q101, manufactured in IATF 16949 facilities, and supports PPAP documentation - required for automotive production deployment.
How does the PowerDI123 package improve surge handling versus SOD-123?
PowerDI123 provides 3× lower thermal resistance (RθJS = 6°C/W vs. ~20°C/W for SOD-123) and 2.5× higher surge current capacity due to its exposed cathode tab and optimized copper leadframe - enabling reliable 24.5A pulse handling without bond wire failure or thermal runaway under repeated stress.
