Product details
Overview
SMBJ60CAQ-13-F from Diodes Incorporated is a bi-directional automotive-grade transient voltage suppressor (TVS) diode in SMB package, rated for 600W peak pulse power, 60V reverse standoff voltage (VRWM), and 96.8V max clamping voltage at 6.2A peak pulse current; designed to protect CAN, LIN, and sensor interfaces in engine control units and body electronics against ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD surges.
For engineers reviewing the SMBJ60CAQ-13-F datasheet, SMBJ60CAQ-13-F pinout, SMBJ60CAQ-13-F application, or SMBJ60CAQ-13-F equivalent, key selection criteria include clamping voltage margin relative to system rail, bidirectional surge symmetry for AC-coupled data lines, AEC-Q101 qualification status, IATF 16949 manufacturing traceability, and RoHS/halogen-free compliance for automotive Tier-1 supply chain requirements.
Technical Context
This bi-directional TVS operates symmetrically across both polarities with identical breakdown (66.7–73.7V) and clamping (96.8V @ 6.2A) characteristics, enabling robust protection of differential buses like CAN FD without polarity sensitivity. Its 1.0mA test current and 0.5µA max reverse leakage at VRWM ensure minimal standby loading on 12V/24V automotive rails.
Thermally rated for -55°C to +175°C junction operation and packaged in UL 94V-0 molded plastic, it sustains 5W steady-state dissipation at TL = +75°C with 4.8W/°C derating above +25°C ambient-critical for under-hood placement near ECUs and ADAS modules exposed to thermal cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - withstands ISO7637-2 Pulse 3b (+150V, 10×1000µs) without failure |
| Reverse Standoff Voltage (VRWM) | 60V - blocks normal 12V/24V system transients up to 60V before clamping activates |
| Max Clamping Voltage (VC) | 96.8V @ IPP = 6.2A - limits downstream IC stress during 10×1000µs surge events |
| Breakdown Voltage (VBR) | 66.7–73.7V @ IT = 1.0mA - defines precise turn-on threshold with tight 10.5% tolerance |
| Reverse Leakage (IR) | ≤0.5µA @ VRWM - negligible quiescent current draw on always-on vehicle networks |
| Operating Temperature | -55°C to +175°C - supports placement in high-temp engine bay or transmission control units |
| AEC-Q101 Qualified | Yes - validated for automotive reliability including HTOL, TCT, and ESD testing per AEC standard |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, 2-terminal bi-directional device with no polarity marking; dimensions: 3.30–3.94mm (D) × 5.00–5.59mm (E) × 2.00–2.50mm (A); weight ≈ 0.1g; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional surge path | Both terminals function identically-no orientation required during PCB placement |
| Case (SMB body) | Thermal conduction path | Primary heat dissipation route to PCB copper; requires ≥25mm² thermal pad for full 5W rating |
Key Features
| Feature | Design Value |
|---|---|
| 600W Peak Pulse Rating | Enables single-device protection against worst-case ISO7637-2 Pulse 1 (-150V) and Pulse 3a (-220V) without cascaded clamping |
| AEC-Q101 Qualified & PPAP Capable | Meets automotive change control requirements with full process documentation and lot traceability for Tier-1 production |
| RoHS / Halogen-Free / "Green" | Complies with EU Directive 2015/863/EU and Diodes' halogen-free definition (<900ppm Br, <900ppm Cl, <1000ppm Sb) |
| Low Capacitance (Typ. 100pF) | Preserves signal integrity on 500kbps CAN and 20kbps LIN buses without edge distortion or timing jitter |
Applications
| Engine Control Unit (ECU) Power Input | CAN FD Data Line Protection |
|---|---|
Use Scenario: 12V battery feed to microcontroller power supply in gasoline/diesel ECUs exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Primary overvoltage clamp upstream of DC-DC converter input, responding within nanoseconds to transients exceeding 60V. Use Value: Limits input voltage to ≤96.8V during ISO7637-2 Pulse 1 (-150V), preventing damage to 3.3V/5V LDOs and MCU VDD pins. | Use Scenario: Bidirectional protection of CAN_H/CAN_L differential pair in ADAS domain controllers operating at 2–5Mbps. IC Role / Device Role / Timing Role: Symmetric clamping element placed across bus lines, activated only during ESD or coupled surge events. Use Value: Maintains <100pF line-to-line capacitance to avoid CAN FD bit-rate degradation while clamping ±30kV contact discharge per ISO10605. |
| Body Control Module (BCM) Sensor Interface | Electric Power Steering (EPS) Motor Driver |
Use Scenario: Protection of analog inputs (e.g., temperature, pressure sensors) connected to 5V reference rails in BCMs. IC Role / Device Role / Timing Role: Low-leakage (≤0.5µA) standoff device that remains inactive during normal 0–5V sensor output swing. Use Value: Prevents latch-up or offset drift in precision op-amps and ADC front-ends during ignition-switching transients (ISO7637-2 Pulse 2a). | Use Scenario: Gate-drive circuit protection in 3-phase EPS motor inverters subject to inductive kickback and ground bounce. IC Role / Device Role / Timing Role: Fast-response clamp across high-side/low-side gate drivers to suppress >100V spikes induced by MOSFET switching. Use Value: Ensures gate oxide integrity by limiting driver IC VGS stress to <96.8V during 10×1000µs inductive surges per ISO7637-2 Pulse 3b. |
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 |
|---|---|---|---|
| SAC60CA | Same 60V VRWM and 96.8V VC, but in SMC package (higher 1500W PPK, larger footprint) | Better suited for higher-energy surges where board space allows SMC; not drop-in compatible with SMB layout | Select when surge energy exceeds 600W or thermal mass requirements demand larger package |
| SMCJ60CA | Identical electrical specs, same SMB footprint, but non-automotive grade (no AEC-Q101 or PPAP) | Lacks automotive qualification documentation and IATF 16949 traceability; unsuitable for Tier-1 production | Acceptable for prototyping or non-automotive industrial use where qualification is not mandated |
Compared with SAC60CA and SMCJ60CA, SMBJ60CAQ-13-F uniquely delivers AEC-Q101 qualification, PPAP readiness, and halogen-free compliance in the compact SMB footprint-making it the only choice for volume automotive production where footprint, qualification, and regulatory alignment are jointly constrained.

FAQ
What does the 'AQ' suffix signify in SMBJ60CAQ-13-F?
The 'AQ' suffix denotes Diodes Incorporated's automotive qualification designation: AEC-Q101 stress-tested, manufactured in IATF 16949-certified facilities, PPAP-capable, and compliant with RoHS 3 and halogen-free standards. It distinguishes this part from commercial-grade variants like SMBJ60CA-13-F.
Is SMBJ60CAQ-13-F unidirectional or bidirectional, and how is polarity identified?
SMBJ60CAQ-13-F is bi-directional, indicated by the 'C' in the part number. Unlike uni-directional SMBJ60AQ-13-F, it has no cathode band or polarity marking-both terminals are functionally identical, enabling simplified layout on differential or AC-coupled signal lines such as CAN or LIN.
How does SMBJ60CAQ-13-F perform under repeated surge exposure?
This device is rated for non-repetitive surges only: maximum 4 pulses per minute at 8.3ms half-sine waveform. For repetitive transients, thermal accumulation must be modeled using its 4.8W/°C derating curve and 5W steady-state limit at TL = +75°C; sustained surge duty cycles require parallel TVS or active clamping.
Can SMBJ60CAQ-13-F replace SMBJ60A-13-F in an existing design?
No-SMBJ60A-13-F is uni-directional with cathode marking and asymmetric clamping behavior, while SMBJ60CAQ-13-F is bi-directional with symmetrical VBR and VC. Substitution requires PCB layout revision to remove polarity constraints and verify clamping symmetry meets system-level surge test requirements.
