Product details
Overview
SMAJ6.0AQ-13-F from Diodes Incorporated is a unidirectional 400W automotive transient voltage suppressor (TVS) diode with 6.0V reverse standoff voltage, 10.3V max clamping voltage at 38.8A peak pulse current, and AEC-Q101 qualification for under-hood power line protection in ISO7637-2 Pulse 1/2a/3a/3b-compliant systems.
For engineers reviewing the SMAJ6.0AQ-13-F datasheet, SMAJ6.0AQ-13-F pinout, SMAJ6.0AQ-13-F application, or SMAJ6.0AQ-13-F equivalent, key selection criteria include clamping voltage margin vs. system rail, peak pulse current capability under 10×1000μs waveform, unidirectional polarity for DC-biased lines, and IATF 16949 manufacturing traceability.
Technical Context
This TVS diode operates as a fast-acting shunt clamp on automotive 12V supply rails, triggering at 6.67V (min breakdown) and limiting transients to ≤10.3V at 38.8A. Its glass-passivated junction ensures stable leakage (<800µA at 6.0V) and robust surge handling across -55°C to +175°C junction temperature range.
Designed specifically for ISO10605 ESD (±30kV air/contact) and ISO7637-2 transient immunity, it delivers 400W non-repetitive peak pulse power with 8.3ms half-sine surge rating and 1.0W steady-state dissipation at 75°C lead temperature - enabling direct placement at connector entry points without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400W - sustains single 10×1000μs transients per ISO7637-2 without degradation |
| Reverse Standoff Voltage | 6.0V - sets minimum operating rail margin before clamping activation |
| Max Clamping Voltage | 10.3V @ 38.8A - defines worst-case overvoltage seen by protected ICs during surge |
| Breakdown Voltage | 6.67–7.37V @ 10mA - ensures reliable turn-on with controlled voltage tolerance |
| Leakage Current | <800µA @ 6.0V - prevents excessive quiescent drain on battery-backed circuits |
| Operating Temp Range | -55°C to +175°C - supports engine compartment mounting with full electrical specs retained |
Pinout & Package
Package: SMA (Surface Mount Assembly), molded plastic UL 94V-0 housing, 0.064g mass, cathode band polarity indicator, matte tin lead finish compliant with MIL-STD-202 soldering standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-impedance return path; enables unidirectional clamping from rail to GND |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., battery feed); conducts surge current to ground when VAK ≥ VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood use with PPAP documentation and IATF 16949 manufacturing control |
| Glass-passivated die | Ensures long-term stability of VBR and leakage under thermal cycling and humidity stress |
| Lead-free & halogen-free | RoHS 3 (2015/863/EU) compliant with <900ppm Br/Cl and <1000ppm Sb - meets global automotive ELV requirements |
| ISO7637-2 Pulse 1/2a/3a/3b rated | Clamps -100V, +50V, -150V, +100V transients without failure - eliminates need for external filtering stages |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) LIN Bus Line |
|---|---|
Use Scenario: 12V battery feed to microcontroller power supply in gasoline/diesel engine compartments exposed to load dump and alternator ripple.

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-13-F | No AEC-Q101 qualification; standard industrial grade; same electrical specs and package | Not approved for automotive PPAP; limited to non-safety-critical consumer or industrial power rails | Select only for cost-sensitive non-automotive designs where change control and IATF 16949 traceability are not required |
| SMCJ6.0A-Q | Higher 1500W peak power; DO-214AB package; same 6.0V VRWM and AEC-Q101 rating | Used where higher surge energy (e.g., heavy-duty truck load dump) exceeds 400W capability | Choose when system-level testing reveals insufficient margin with 400W rating - requires PCB layout change due to larger footprint |
Compared with SMAJ6.0A-13-F, SMAJ6.0AQ-13-F adds automotive-grade reliability controls and documentation; compared with SMCJ6.0A-Q, it trades surge capacity for compact SMA footprint - making it optimal for space-constrained ECUs needing certified transient immunity.

FAQ
What is the maximum clamping voltage of SMAJ6.0AQ-13-F at its rated peak pulse current?
The maximum clamping voltage is 10.3V at 38.8A peak pulse current under the standardized 10×1000μs waveform defined in IEC 61000-4-5 and ISO7637-2. This value is guaranteed across the full operating temperature range and represents the upper limit of overvoltage imposed on protected circuitry during surge events.
Is SMAJ6.0AQ-13-F suitable for bidirectional signal line protection?
No - SMAJ6.0AQ-13-F is a unidirectional TVS diode with cathode band marking and specified only for DC-biased applications like power rails. For bidirectional protection (e.g., CAN, LIN, USB), the bi-directional variant SMAJ6.0CAQ-13-F must be used, which has symmetrical clamping in both polarities and no polarity indicator.
How does the AEC-Q101 qualification impact the manufacturing process of SMAJ6.0AQ-13-F?
AEC-Q101 qualification mandates wafer-level and final-test screening including HTGB, HTRB, TCT, and ESD testing per JEDEC standards, plus full PPAP documentation, IATF 16949-certified production facilities, and controlled change management - ensuring zero defects in automotive deployment over 15+ years of thermal cycling and vibration exposure.
What is the steady-state power dissipation limit for SMAJ6.0AQ-13-F at elevated temperatures?
At TL = +75°C lead temperature, the steady-state power dissipation is rated at 1.0W. Derating follows the curve in Figure 6 of DS40739: power drops linearly to zero at +175°C junction temperature, requiring thermal design that maintains lead temperature ≤75°C under continuous DC leakage conditions.
