Product details
Overview
DFLT5V0AQ-7 from Diodes Incorporated is an AEC-Q101 qualified, automotive-grade transient voltage suppressor (TVS) diode in PowerDI 123 package. It provides 225W peak pulse power dissipation (10/1000µs), 5.0V reverse standoff voltage, 6.4–7.0V breakdown voltage at 10mA, and clamps to ≤9.2V at 24.5A peak pulse current. Designed for CAN bus, LIN, and automotive sensor interface protection.
For engineers reviewing the DFLT5V0AQ-7 datasheet, DFLT5V0AQ-7 pinout, DFLT5V0AQ-7 application, or DFLT5V0AQ-7 equivalent, key selection criteria include clamping voltage vs. IPP, junction-to-solder thermal resistance (6°C/W), AEC-Q101 qualification status, PowerDI 123 footprint compatibility, and low 400µA leakage at VRWM.
Technical Context
This unidirectional TVS diode operates as a shunt-type overvoltage protector with cathode-band polarity. Its silicon avalanche structure delivers fast response (<1ns) to ESD and surge transients per IEC 61000-4-2 (±30kV contact) and ISO 16750-2 (load dump, pulse 5a). The device is optimized for low-capacitance operation (≈300pF at 0V bias) to preserve signal integrity on high-speed automotive data lines.
Thermal design leverages the PowerDI 123's low RθJS of 6°C/W to sustain repetitive surges without thermal runaway. The 1.0W DC power rating and 120°C/W RθJA (on FR-4 with 1"² 2oz copper) support robust board-level thermal management in engine control units and body electronics modules.
Key Specifications

Applications
| Automotive CAN Bus Protection | Engine Control Unit (ECU) Power Input |
|---|---|
Use Scenario: Protecting high-speed CAN FD transceivers against load dump and jump-start transients in vehicle networking. IC Role / Device Role / Timing Role: Shunt TVS placed between CANH/CANL lines and chassis ground to clamp common-mode surges. Use Value: Clamps to ≤9.2V within nanoseconds, preventing transceiver latch-up while maintaining <300pF capacitance for 5Mbps signal fidelity. |
Use Scenario: Safeguarding 5V microcontroller power rails in engine bay ECUs exposed to ISO 16750-2 pulse 5a (load dump). IC Role / Device Role / Timing Role: Unidirectional TVS connected between VCC and GND to absorb positive-going voltage spikes. Use Value: Withstands 225W pulses without degradation, enabling compliance with automotive reliability lifetime targets (>15 years). |
| LIN Bus Node Protection | Body Control Module Sensor Interface |
Use Scenario: Shielding LIN transceivers in door modules and seat controllers from ESD and battery disconnect transients. IC Role / Device Role / Timing Role: Low-leakage (400µA) TVS placed across LIN bus pins to suppress ±30kV contact ESD per IEC 61000-4-2. Use Value: Maintains system wake-up capability by limiting standby current impact while providing sub-10V clamping. |
Use Scenario: Protecting analog inputs of temperature/pressure sensors in HVAC and lighting control modules. IC Role / Device Role / Timing Role: Signal-line TVS installed between sensor output and MCU ADC input to prevent overvoltage damage. Use Value: 300pF capacitance avoids filtering of slow-varying sensor signals (e.g., thermistor voltage ramps), preserving measurement accuracy. |
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-Q | Same 5.0V VRWM but SMA package (RθJA = 140°C/W); lower PPK = 400W (but derates faster above 25°C) | Less suitable for high-temperature underhood locations due to higher thermal resistance | Prefer when cost-sensitive industrial designs allow larger footprint and relaxed thermal constraints |
| TPSMF5.0A | 5.0V VRWM, 200W PPK, SOD-123FL package; RθJS = 12°C/W; no AEC-Q101 certification | Not qualified for automotive use; lacks PPAP documentation and IATF 16949 traceability | Select only for non-automotive consumer or industrial applications where qualification is not required |
Compared with SMAJ5.0A-Q and TPSMF5.0A, DFLT5V0AQ-7 uniquely combines AEC-Q101 qualification, PowerDI 123's superior thermal performance (RθJS = 6°C/W), and automotive-specific packaging-making it the only choice for production-grade CAN/LIN protection in certified vehicle systems.

FAQ
What is the maximum operating temperature for DFLT5V0AQ-7?
The DFLT5V0AQ-7 is rated for continuous operation from –55°C to +150°C junction temperature. Its PowerDI 123 package and low RθJS (6°C/W) enable reliable performance in under-hood environments such as engine control units, where ambient temperatures exceed 125°C and thermal cycling is severe.
Does DFLT5V0AQ-7 meet IEC 61000-4-2 ESD immunity requirements?
Yes-DFLT5V0AQ-7 is validated for ±30kV contact discharge per IEC 61000-4-2. Its sub-1ns response time and low clamping voltage (≤9.2V) ensure protected downstream ICs remain within safe operating limits during ESD events, making it suitable for automotive infotainment and sensor interfaces.
Can DFLT5V0AQ-7 be used in bidirectional configurations?
No-DFLT5V0AQ-7 is a unidirectional TVS diode, designed for clamping positive transients only. For bidirectional protection (e.g., AC signal lines), a dedicated bidirectional device such as DFLT5.0UQ-7 must be selected; mixing unidirectional devices in anti-parallel is not recommended due to mismatched breakdown characteristics.
What is the meaning of the "AQ" suffix in DFLT5V0AQ-7?
The "AQ" suffix denotes Diodes Incorporated's automotive qualification designation: AEC-Q101 compliant, manufactured in IATF 16949-certified facilities, PPAP-capable, and subject to enhanced change control. It distinguishes this grade from commercial-grade equivalents (e.g., DFLT5V0M-7) which lack automotive validation and documentation.
