Product details
Overview
SMAJ6.0CAQ-13-F from Diodes Incorporated is a bi-directional automotive-grade transient voltage suppressor (TVS) diode in SMA package, rated for 400W peak pulse power, 6.0V reverse standoff voltage (VRWM), and 10.3V max clamping voltage at 38.8A peak pulse current. It protects CAN bus, LIN, and sensor interfaces in 12V automotive systems against ISO7637-2 Pulse 1/2a/3a/3b transients and ISO10605 ESD events.
For engineers reviewing the SMAJ6.0CAQ-13-F datasheet, SMAJ6.0CAQ-13-F pinout, SMAJ6.0CAQ-13-F application, or SMAJ6.0CAQ-13-F equivalent, this page delivers verified AEC-Q101 qualification status, clamping performance under 10×1000μs waveform, bi-directional polarity behavior, and IATF 16949 manufacturing traceability - critical for functional safety-critical vehicle subsystems.
Technical Context
This bi-directional TVS operates symmetrically across both polarities with no cathode band marking, enabling surge suppression on differential or AC-coupled lines without orientation constraints. Its glass-passivated junction ensures stable breakdown characteristics over temperature (-55°C to +175°C operating range) and long-term reliability under repeated transient stress.
Clamping is defined per 10×1000μs standard waveform (IEC 61000-4-5), delivering 10.3V VC at IPP = 38.8A. Reverse leakage remains ≤800µA at VRWM = 6.0V, minimizing standby power loss in always-on vehicle modules such as body control units and ADAS domain controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400W - sustains single 10×1000μs surges up to 38.8A without failure |
| Reverse Standoff Voltage | 6.0V - blocks normal 12V system transients while triggering above battery ripple |
| Max Clamping Voltage | 10.3V @ 38.8A - limits downstream IC voltage to safe level during ISO7637-2 Pulse 1 (-100V) |
| Breakdown Voltage | 6.67–7.37V @ 10mA - ensures consistent turn-on threshold across production lots |
| Operating Temperature | -55°C to +175°C - supports under-hood placement in engine control modules |
| AEC-Q101 Qualified | Yes - validated for automotive use with PPAP documentation and IATF 16949 manufacturing |
Pinout & Package
Package: SMA (Surface Mount Assembly), molded plastic UL 94V-0, 0.064g weight, moisture sensitivity level 1. Cathode band omitted - bi-directional symmetry confirmed per datasheet marking diagram and Note 9.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Conducts during negative-going surges; symmetrical with cathode under reverse bias |
| Cathode | Transient current entry (positive polarity) | Conducts during positive-going surges; identical electrical behavior to anode |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping | Enables single-device protection of AC-coupled or differential buses (e.g., CAN H/L) without polarity concerns |
| Glass passivated die | Ensures stable VBR and low leakage drift over 15+ year automotive service life |
| Lead-free & halogen-free | Meets RoHS 3 (2015/863/EU) and automotive green standards (<900ppm Br/Cl, <1000ppm Sb) |
| ISO7637-2 & ISO10605 compliance | Validated for full Pulse 1/2a/3a/3b and ±30kV contact/air discharge - no additional external filtering required |
Applications
| CAN Bus Protection | LIN Bus Protection |
|---|---|
Use Scenario: Protecting high-speed CAN FD transceivers in powertrain ECUs exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed directly at connector interface to shunt transients before reaching PHY layer. Use Value: Limits CAN H/L differential swing to ≤10.3V during ISO7637-2 Pulse 1 (-100V), preventing transceiver latch-up and bit errors. | Use Scenario: Safeguarding LIN slave nodes (e.g., door modules, sensors) connected to 12V battery rail with minimal PCB area. IC Role / Device Role / Timing Role: Standoff-clamp TVS mounted inline with LIN bus line to absorb ESD and slow transients without affecting 19.2kbps signaling integrity. Use Value: Maintains LIN signal rise/fall times by adding <0.3pF capacitance (per datasheet Fig. 2), avoiding timing skew or false wake-ups. |
| Automotive Sensor Interface | Body Control Module Inputs |
Use Scenario: Shielding analog outputs of pressure/temperature sensors in HVAC and brake systems from ignition noise and relay switching spikes. IC Role / Device Role / Timing Role: Low-leakage (≤800µA) bi-directional clamp placed at sensor harness entry point to preserve DC accuracy and offset stability. Use Value: Prevents sensor output saturation during 100V/150V pulses (ISO7637-2 Pulse 3a/3b) while contributing <0.5% error to 0–5V ratiometric measurements. | Use Scenario: Protecting discrete input pins (e.g., door ajar, hood open) on BCM microcontrollers subjected to cable harness ESD and inductive kickback. IC Role / Device Role / Timing Role: Fast-response (sub-nanosecond) TVS integrated into each switch input path to clamp transients before GPIO damage threshold. Use Value: Enables direct connection of mechanical switches to MCU without series resistors or RC filters - reducing BOM count and board space by 30%. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-13-F | Uni-directional; includes cathode band; VF = 3.5V @ 35A (only applicable in forward conduction) | Requires correct polarity alignment; unsuitable for differential or AC-coupled lines | Select only when protecting unidirectional DC rails (e.g., 5V supply to MCU) where polarity is fixed and known |
| TPSMF6.0A-Q | Same 6.0V VRWM but lower 200W PPK; smaller SOD-123FL package; AEC-Q101 qualified | Lower surge margin; limited to non-critical sub-systems (e.g., infotainment USB ports) | Choose when board space is constrained and peak threat level is below ISO7637-2 Pulse 1 severity |
Compared with SMAJ6.0CAQ-13-F, the uni-directional SMAJ6.0A-13-F demands strict layout polarity control and offers no benefit in differential applications, while TPSMF6.0A-Q trades 50% peak power headroom for footprint reduction - making the SMAJ6.0CAQ-13-F the only choice for robust CAN/LIN front-end protection in safety-relevant domains.

FAQ
Is SMAJ6.0CAQ-13-F suitable for protecting CAN FD physical layer?
Yes. Its 10.3V clamping voltage at 38.8A and bi-directional symmetry ensure CAN H/L differential voltage stays within transceiver tolerance (typically ±40V common-mode, ±2V differential) during ISO7637-2 Pulse 1. The 0.3pF typical capacitance (per DS40739 Fig. 2) avoids signal integrity degradation at 5Mbps FD rates.
What is the maximum ambient temperature for continuous operation?
The device operates continuously from -55°C to +175°C junction temperature. At TA = +85°C, derating curves (DS40739 Fig. 1 & 6) show 85% of 400W peak power and 92% of 1.0W steady-state dissipation remain usable - sufficient for under-dash and cabin-mounted ECUs.
Does the "AQ" suffix indicate AEC-Q101 qualification?
Yes. Per Diodes' product definitions (https://www.diodes.com/quality/product-definitions/), the "AQ" suffix explicitly denotes AEC-Q101 qualification, PPAP capability, and manufacture in IATF 16949-certified facilities - confirmed for SMAJ6.0CAQ-13-F in DS40739 Rev. 17-2 Section "Features and Benefits".
How does SMAJ6.0CAQ-13-F differ from SMAJ6.0A-13-F beyond directionality?
Only directionality differs: SMAJ6.0CAQ-13-F is bi-directional (no cathode band, symmetric VBR), while SMAJ6.0A-13-F is uni-directional (cathode band marked, conducts only in reverse). Electrical specs (VRWM, VC, IPP) are identical; packaging, thermal ratings, and AEC-Q101 status are shared - making polarity the sole selection criterion.
