Product details
Overview
SMBJ6.0AQ-13-F from Diodes Incorporated is a unidirectional 600W surface-mount automotive transient voltage suppressor (TVS) diode with 6.0V reverse standoff voltage, 10.3V max clamping voltage at 58.3A peak pulse current, and AEC-Q101 qualification. It protects CAN bus, LIN, and body control modules against ISO7637-2 Pulse 1 (−150V), Pulse 2a (+112V), and ISO10605 ESD (±30kV).
For engineers reviewing the SMBJ6.0AQ-13-F datasheet, SMBJ6.0AQ-13-F pinout, SMBJ6.0AQ-13-F application, or SMBJ6.0AQ-13-F equivalent, this device is selected for automotive power line surge protection where low clamping voltage, high IFSM (100A), and IATF 16949 traceable manufacturing are required.
Technical Context
This TVS diode operates as a unidirectional clamping device in parallel with protected circuitry, triggering when reverse voltage exceeds 6.67V (min VBR) to shunt surge energy to ground. Its 600W peak pulse power rating is defined per 10×1000μs waveform, with thermal derating starting above +25°C at 4.8W/°C.
Designed for automotive environments, it meets ISO10605 (150pF/330Ω, ±30kV air/contact discharge) and ISO7637-2 Pulse 1, 2a, and 3a/b waveforms. The SMB package supports lead-free reflow soldering per MIL-STD-202 and has moisture sensitivity level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 10×1000μs transients without failure |
| Reverse Standoff Voltage (VRWM) | 6.0V - maximum continuous DC or RMS voltage before clamping initiates |
| Breakdown Voltage (VBR) | 6.67–7.37V @ 10mA - precise turn-on threshold for predictable clamping onset |
| Max Clamping Voltage (VC) | 10.3V @ 58.3A - limits downstream voltage stress during worst-case surge |
| Peak Forward Surge Current (IFSM) | 100A @ 8.3ms half-sine - handles repetitive load dump surges in 12V systems |
| Steady-State Power (PM(AV)) | 5.0W @ TL = +75°C - defines continuous dissipation limit under thermal constraint |
| Operating Temperature | −55°C to +175°C - supports under-hood placement in modern engine compartments |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, molded plastic UL 94V-0 housing; cathode band denotes polarity on unidirectional variant; weight ≈ 0.1g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge return path | Connected to system ground or chassis to complete clamping loop during overvoltage events |
| Cathode | Protected line connection | Connected to +12V rail or signal line; reverse-biased during normal operation, avalanches during surge |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power | Enables robust protection against severe ISO7637-2 Pulse 1 (−150V) and load dump events without degradation |
| AEC-Q101 qualified | Validated for automotive use with PPAP capability and IATF 16949 certified manufacturing |
| Low clamping ratio (VC/VRWM = 1.72) | Minimizes voltage overshoot across protected ICs-critical for 5V/3.3V microcontrollers and transceivers |
| Lead-free & halogen-free | Complies with RoHS 3 (2015/863/EU) and Diodes' "Green" definition (<900ppm Br/Cl, <1000ppm Sb) |
| Moisture Sensitivity Level 1 | Eliminates bake requirements prior to reflow, reducing assembly cost and process complexity |
Applications
| Automotive Body Control Module (BCM) | Infotainment Power Supply Input |
|---|---|
|
Use Scenario: Protects 12V input rails of BCMs from battery load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between fused battery feed and DC-DC converter input. Use Value: Clamps to 10.3V during −150V ISO7637-2 Pulse 1, preventing damage to upstream fuse boxes and downstream regulators. |

IC Role / Device Role / Timing Role: Primary surge clamp on 12V auxiliary input before buck converter and LDO stages. Use Value: Withstands 30kV contact ESD per ISO10605 while maintaining <1µA leakage at 6.0V, preserving standby current budget. |
| CAN FD Transceiver Interface | Electric Power Steering (EPS) Sensor Supply |
|
Use Scenario: Guards CAN_H/CAN_L lines against coupled transients from adjacent high-current motor drivers. IC Role / Device Role / Timing Role: Bi-directional clamping (using SMBJ6.0CQ variant) across differential pair, referenced to ground. Use Value: Limits common-mode surge to <10.3V peak, ensuring transceiver survival during ISO7637-2 Pulse 3b (+150V) injection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A-Q | Same electrical specs; non-AEC-Q101, manufactured in non-IATF 16949 facility | Limited to non-safety-critical consumer or industrial use; no PPAP support | Select only if automotive qualification and supply chain traceability are not required |
| TPSMA6.0A | Identical VRWM (6.0V), but lower PPK (400W); VC = 10.5V @ 38.2A; same SMB package | Insufficient for ISO7637-2 Pulse 1 (−150V); suitable only for lighter-duty ESD-only protection | Use only in cost-sensitive non-automotive designs where 600W surge immunity is unnecessary |
Compared with SMBJ6.0AQ-13-F, SMBJ6.0A-Q lacks AEC-Q101 validation and traceable automotive sourcing, while TPSMA6.0A trades 33% peak power capacity for lower cost-neither matches its combination of 600W rating, 10.3V clamping, and full automotive compliance.

FAQ
What is the clamping voltage of SMBJ6.0AQ-13-F at its rated peak pulse current?
The maximum clamping voltage (VC) is 10.3V at 58.3A peak pulse current, measured per the 10×1000μs waveform specified in the datasheet. This value ensures downstream 5V logic and CAN transceivers remain within absolute maximum ratings during surge events.
Is SMBJ6.0AQ-13-F suitable for bi-directional surge protection?
No-it is a unidirectional TVS diode, indicated by the absence of "C" in the part number. For bi-directional protection (e.g., differential data lines), the SMBJ6.0CQ-13-F variant must be used, which provides symmetrical clamping for both polarities.
Does SMBJ6.0AQ-13-F require derating at elevated ambient temperatures?
Yes-its peak pulse power derates linearly above +25°C at 4.8W/°C, and steady-state power dissipation is limited to 5.0W at lead temperature +75°C. Thermal design must account for PCB copper area and airflow to maintain safe junction temperature.
How does SMBJ6.0AQ-13-F differ from commercial-grade SMBJ6.0A?
SMBJ6.0AQ-13-F adds AEC-Q101 qualification, PPAP documentation support, and manufacturing in IATF 16949-certified facilities-requirements essential for Tier 1 automotive suppliers. Electrically identical, but with full automotive change control and traceability.
