Product details
Overview
SMBJ75CAQ-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, 75V reverse standoff voltage (VRWM), and 121V maximum clamping voltage (VC) at 4.9A peak pulse current. It protects 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 SMBJ75CAQ-13-F datasheet, SMBJ75CAQ-13-F pinout, SMBJ75CAQ-13-F application, or SMBJ75CAQ-13-F equivalent, this page delivers verified AEC-Q101 qualification status, exact clamping behavior under 10/1000μs transients, IATF 16949 manufacturing traceability, and RoHS/halogen-free compliance - critical for automotive Tier-1 BOM validation and PPAP submission.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) specified at 83.3V min / 92.1V max under 1.0mA test current. Its clamping response is characterized per 10×1000μs waveform, delivering 121V VC at IPP = 4.9A - enabling robust protection of 12V/24V automotive subsystems without forward conduction during normal operation.
Thermally rated for -55°C to +175°C junction temperature and packaged in UL 94V-0 molded plastic, it sustains 5.0W steady-state power at TL = +75°C and derates linearly above +25°C (4.8W/°C). Moisture sensitivity is Level 1 per J-STD-020, supporting standard SMT reflow without baking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - withstands ISO7637-2 Pulse 3b (150V, 50ms) and ISO10605 30kV contact discharge without failure |
| Reverse Standoff Voltage (VRWM) | 75V - blocks leakage below system overvoltage threshold while allowing normal 12V/24V bus operation |
| Clamping Voltage (VC) | 121V @ IPP = 4.9A - limits downstream IC stress to safe levels during 10/1000μs transients |
| Breakdown Voltage (VBR) | 83.3–92.1V @ IT = 1.0mA - ensures precise, repeatable avalanche initiation for predictable protection timing |
| Leakage Current (IR) | ≤0.5µA @ VRWM - negligible standby power loss in always-on automotive modules |
| Operating Temperature | -55°C to +175°C - qualified for under-hood ECU placement without thermal derating penalties |
| AEC-Q101 Qualified | Yes - validated for automotive use with PPAP capability and IATF 16949 manufacturing control |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bi-directional configuration with no polarity marking. Dimensions: 3.30–3.94mm (D) × 5.00–5.59mm (E) × 2.00–2.50mm (A), weight ≈0.1g. UL 94V-0 flammability rating; matte tin lead finish, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Cathode Band Absent) | Bi-directional surge path terminal | No polarity - connects to protected line (e.g., CAN_H or LIN) with identical clamping in both directions |
| Cathode (Cathode Band Absent) | Bi-directional surge path terminal | Paired with Anode to form symmetrical avalanche structure; enables bidirectional transient shunting |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power | Supports full ISO7637-2 Pulse 1 (-150V) and Pulse 3a (-220V) without degradation in automotive 12V systems |
| AEC-Q101 qualification | Validated for automotive use with HTOL, TC, UHAST, and ESD testing per AEC specification |
| RoHS & halogen-free | Meets EU RoHS 3 (2015/863/EU); Br+Cl <1500ppm, Sb <1000ppm - compliant for global vehicle programs |
| Low clamping ratio (VC/VBR ≈ 1.46) | Minimizes voltage overshoot during fast transients, reducing risk of latch-up in connected MCUs and transceivers |
| Level 1 moisture sensitivity | Enables direct placement after dry pack opening - no bake required before reflow |
Applications
| Engine Control Unit (ECU) Power Input | CAN FD Transceiver 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: Primary overvoltage clamp on main VBAT rail, placed upstream of DC-DC converter input. Use Value: Clamps ISO7637-2 Pulse 1 (-150V) to ≤121V, preventing damage to 40V-rated input MOSFETs and LDOs. |
Use Scenario: Bidirectional protection of CAN_H/CAN_L lines in ADAS domain controllers operating at 5Mbps. IC Role / Device Role: Line-side TVS parallel to CAN transceiver, absorbing ESD and coupled noise from harness. Use Value: Symmetric 121V clamping preserves signal integrity during ±30kV ISO10605 discharges without forward biasing. |
| Body Control Module (BCM) LIN Bus | Automotive Camera Power Rail |
Use Scenario: LIN physical layer protection in door modules where wiring harnesses induce repetitive transients. IC Role / Device Role: Bi-directional shunt device across LIN bus pins, referenced to local ground. Use Value: 0.5µA IR at 75V VRWM avoids false wake-up in low-power sleep mode while clamping Pulse 3b (+150V). |
Use Scenario: 12V input protection for rear-view camera modules mounted near exhaust or suspension. IC Role / Device Role: First-stage surge suppressor before buck converter, handling under-hood thermal cycling. Use Value: -55°C to +175°C operation ensures reliability at PCB hot spots; 5W PM(AV) supports continuous thermal dissipation. |
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 |
|---|---|---|---|
| SMBJ75CA | Same electrical specs but not AEC-Q101 qualified; RoHS-compliant but not PPAP-capable | Limited to non-automotive industrial or consumer use; not accepted in Tier-1 automotive BOMs | Select only for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
| SMCJ75CAQ-13-F | Higher 1500W PPK rating in larger SMC package; same VRWM/VC but 10.9A IPP | Better suited for high-energy transients (e.g., heavy-duty truck load dump) requiring >600W margin | Choose when system-level testing shows SMBJ75CAQ-13-F clamping margin is insufficient under worst-case ISO7637-2 Pulse 1 |
Compared with SMBJ75CA and SMCJ75CAQ-13-F, SMBJ75CAQ-13-F uniquely balances AEC-Q101 compliance, SMB footprint constraints, and 600W surge handling - making it optimal for space-constrained automotive modules where qualification and size are jointly critical.

FAQ
Is SMBJ75CAQ-13-F unidirectional or bidirectional?
SMBJ75CAQ-13-F is a bi-directional TVS diode, indicated by the "C" suffix in its part number. It provides symmetrical clamping for both positive and negative transients without polarity orientation during PCB layout - essential for differential buses like CAN and LIN.
What is the maximum clamping voltage at rated peak pulse current?
At 4.9A peak pulse current (IPP), SMBJ75CAQ-13-F clamps to a maximum of 121V under the standardized 10×1000μs waveform. This value is guaranteed across temperature and lifetime per DS40740 Rev. 15-2, ensuring consistent protection margin in automotive environments.
Does this part meet AEC-Q101 requirements for automotive use?
Yes - SMBJ75CAQ-13-F is fully AEC-Q101 qualified, manufactured in IATF 16949-certified facilities, and PPAP-capable. Test reports cover HTOL, temperature cycling, UHAST, and ESD per AEC-Q101 Rev. D, with documentation available upon request for Tier-1 validation.
How does SMBJ75CAQ-13-F differ from standard SMBJ75CA?
SMBJ75CAQ-13-F adds automotive-specific qualifications: AEC-Q101 certification, PPAP readiness, and IATF 16949 manufacturing control. Electrically identical to SMBJ75CA, it differs only in traceability, change control, and qualification documentation - mandatory for OEM automotive programs.
