Product details
Overview
SMCJ5.0AQ-13-F from Diodes Incorporated is a unidirectional 1,500W automotive-grade transient voltage suppressor (TVS) diode in SMC package, with 5.0V reverse standoff voltage (VRWM), 6.40–7.07V breakdown voltage (VBR), and 9.2V clamping voltage (VC) at 163A peak pulse current. It protects CAN, LIN, and power-line circuits in engine control units and body electronics against ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD surges.
For engineers reviewing the SMCJ5.0AQ-13-F datasheet, SMCJ5.0AQ-13-F pinout, SMCJ5.0AQ-13-F application, or SMCJ5.0AQ-13-F equivalent, this page delivers verified AEC-Q101 qualification status, exact clamping performance under 10/1000μs waveform, thermal derating behavior up to +150°C junction temperature, and RoHS/halogen-free compliance details required for Tier-1 automotive design sign-off.
Technical Context
This TVS diode operates as a unidirectional clamping device with glass-passivated silicon die, enabling sub-nanosecond response to transients. Its 5.0V VRWM ensures compatibility with 5V logic and microcontroller I/O rails, while its 9.2V VC at IPP = 163A provides defined overvoltage protection margin for 12V automotive systems.
Designed for IATF 16949-certified production, it meets ISO7637-2 Pulse 1 (−100V), Pulse 2a (+50V), Pulse 3a (−150V), and Pulse 3b (+100V), and passes ISO10605 ESD testing at ±30kV (air/contact discharge) with 150pF/330Ω network - confirming suitability for front-end power and data line protection in ADAS sensors and infotainment modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single 10/1000μs surge without failure in engine bay environments |
| Reverse Standoff Voltage | 5.0V - blocks normal 5V rail operation while triggering only above threshold |
| Clamping Voltage @ IPP | 9.2V @ 163A - limits downstream IC voltage to safe level during ISO7637-2 Pulse 1 |
| Breakdown Voltage Range | 6.40–7.07V @ IT = 10mA - ensures reliable turn-on with margin below VC |
| Junction Temperature Range | −55°C to +150°C - supports placement near high-heat sources like power converters |
| Steady-State Power | 5.0W @ TL = +75°C - defines continuous dissipation limit with PCB copper heatsinking |
| ESD Rating | ±30kV air/contact per ISO10605 - qualifies for direct connector-level ESD protection |
Pinout & Package
Package: SMC (DO-214AB), molded plastic, UL 94V-0 rated, 0.21g weight, cathode band polarity indicator. Terminals are matte tin-plated, solderable per MIL-STD-202 Method 208.

Applications
| Engine Control Unit (ECU) Power Input | CAN FD Transceiver Protection |
|---|---|
Use Scenario: 12V battery feed to MCU power supply in diesel ECU exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS clamps negative transients (ISO7637-2 Pulse 1) and positive spikes (Pulse 2a/3b) before LDO input. Use Value: Prevents latch-up or permanent damage to 5V-regulated domains during cranking and ignition events. | Use Scenario: CAN FD bus lines (CANH/CANL) in vehicle gateway module subjected to ESD during connector mating. IC Role / Device Role / Timing Role: Bidirectional clamping (via SMCJ5.0CQ variant) limits differential and common-mode surges to <±12V. Use Value: Maintains signal integrity and prevents transceiver reset during ±30kV contact discharge per ISO10605. |
| Body Control Module (BCM) LIN Bus | ADAS Camera Power Rail |
Use Scenario: LIN slave node (e.g., door module) powered from 12V via local DC/DC, subject to cable discharge events. IC Role / Device Role / Timing Role: Unidirectional TVS on VCC rail absorbs fast-rising transients before linear regulator input. Use Value: Eliminates need for secondary RC filtering; enables compact layout with 9.2V clamping ceiling. | Use Scenario: 5V power rail for 12MP image sensor in rear-view camera exposed to hot-swap and vibration-induced arcing. IC Role / Device Role / Timing Role: Primary overvoltage clamp on PMIC output, triggered by ISO7637-2 Pulse 3a (−150V). Use Value: Limits rail excursion to 9.2V, preserving sensor analog front-end and MIPI interface timing margins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC5.0 | Same 5.0V VRWM, but 400W PPK rating and SMA package - lower surge capacity, smaller footprint | Limited to low-energy surges (e.g., board-level ESD); not qualified to ISO7637-2 Pulse 1 | Select when space-constrained and surge energy <200mJ; avoid for battery-line protection. |
| SMCJ5.0A-Q | Identical electrical specs and AEC-Q101 qualification, but non-RoHS (lead-containing terminations) | Acceptable only where legacy Pb-based soldering processes remain in use | Choose only if exempt from RoHS 3; otherwise SMCJ5.0AQ-13-F is direct replacement. |
Compared with SAC5.0 and SMCJ5.0A-Q, SMCJ5.0AQ-13-F uniquely combines 1500W surge handling, AEC-Q101 + PPAP readiness, and halogen-free compliance - making it the sole choice for new automotive designs requiring full OEM validation traceability and green manufacturing requirements.

FAQ
What is the maximum clamping voltage of SMCJ5.0AQ-13-F under standard test conditions?
The maximum clamping voltage is 9.2V measured at 163A peak pulse current using the 10/1000μs waveform per REA and IEC 61000-4-5. This value is guaranteed across the full operating temperature range (−55°C to +150°C) and defines the upper voltage limit imposed on protected circuitry during surge events.
Is SMCJ5.0AQ-13-F suitable for bidirectional signal line protection?
No - SMCJ5.0AQ-13-F is unidirectional. For bidirectional protection (e.g., CAN, USB, or Ethernet), the SMCJ5.0CQ-13-F variant must be used. The "C" suffix denotes bidirectional construction; the "AQ" suffix confirms AEC-Q101 qualification and green material content.
How does the SMCJ5.0AQ-13-F derate with increasing ambient temperature?
Peak pulse power derates linearly above +25°C ambient: at +75°C, it retains ~70% of 1500W (≈1050W); at +125°C, ~40% (≈600W). Derating follows Fig.1 in DS40741 Rev.8-2 and assumes proper PCB copper area (≥1 sq.in. per pad) for thermal conduction.
Does SMCJ5.0AQ-13-F require additional series impedance for optimal protection?
Yes - a current-limiting resistor or ferrite bead is recommended between the TVS and protected IC to reduce let-through energy and prevent excessive diode self-heating during repetitive surges. Typical values are 1–10Ω for power rails and 33–100Ω for data lines, selected based on signal rise time and allowable voltage drop.
