Product details
Overview
SMBJ5.0CAQ-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, 5.0V reverse standoff voltage (VRWM), and 9.2V clamping voltage (VC) at 65.2A peak pulse current. It protects CAN, 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 SMBJ5.0CAQ-13-F datasheet, SMBJ5.0CAQ-13-F pinout, SMBJ5.0CAQ-13-F application, or SMBJ5.0CAQ-13-F equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, IATF 16949 manufacturing, 100A surge rating, and compliance with automotive surge/ESD standards-critical for body control modules, infotainment power rails, and ADAS sensor protection.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, delivering consistent 9.2V clamping under 10×1000μs surge waveforms and maintaining ≤800μA reverse leakage at 5.0V VRWM. Its thermal design supports continuous operation from –55°C to +175°C junction temperature with 5.0W steady-state dissipation at TL = +75°C.
The device uses silicon avalanche junction technology optimized for fast response (<1ns), low capacitance (typ. 1000pF at 0V), and stable clamping over temperature. It is specifically characterized for automotive battery line transients-including –150V Pulse 1, +112V Pulse 2a, and –220V Pulse 3a-without derating below 13.5V system voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 10×1000μs surges without failure in automotive load-dump scenarios |
| Reverse Standoff Voltage (VRWM) | 5.0V - defines maximum continuous operating voltage before significant leakage; matches 5V logic rail protection |
| Clamping Voltage (VC) | 9.2V @ IPP = 65.2A - limits downstream voltage during ISO7637-2 Pulse 1/3a transients to safe levels for 5V ICs |
| Breakdown Voltage (VBR) | 6.40–7.07V @ IT = 10mA - ensures reliable avalanche initiation margin above VRWM for robust turn-on |
| Peak Forward Surge Current (IFSM) | 100A @ 8.3ms half-sine - withstands repetitive cranking surges and alternator load dump without degradation |
| Operating Temperature Range | –55°C to +175°C - qualified for under-hood placement in engine control units and transmission controllers |
| AEC-Q101 Qualified | Yes - validated for automotive use with PPAP capability and IATF 16949 manufacturing traceability |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, molded plastic UL 94V-0 housing, 0.1g weight, moisture sensitivity level 1. Cathode band omitted-bi-directional symmetry eliminates polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Transient current entry (negative polarity) | Conducts during negative-going surges; forms symmetrical path with cathode under reverse bias |
| Cathode (Pin 2) | Transient current entry (positive polarity) | Conducts during positive-going surges; identical electrical behavior to anode due to bi-directional structure |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping | Enables single-device protection of AC-coupled or floating signal lines (e.g., CAN H/L, LIN bus) without polarity concerns |
| ISO10605 ESD compliance | Withstands ±30kV air/contact discharge-eliminates need for external ESD diodes in infotainment and telematics ports |
| Lead-free & halogen-free | Meets RoHS 3 and automotive "Green" requirements (<900ppm Br/Cl, <1000ppm Sb); compatible with lead-free reflow profiles |
| Low clamping ratio (VC/VBR) | 1.45 typical (9.2V / 6.4V) - minimizes voltage overshoot during fast transients, improving system immunity margin |
| Stable leakage at high temp | ≤800μA @ 5.0V, +85°C - prevents excessive quiescent current in always-on vehicle networks (e.g., CAN wake-up circuits) |
Applications
| Body Control Module (BCM) | Infotainment Power Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0C-13-F (Diodes Inc.) | No AEC-Q101 qualification; standard commercial grade; same electrical specs and SMB package | Not approved for automotive production; suitable for industrial or consumer prototyping only | Select when AEC-Q101 is not required and cost optimization is prioritized |
| TPSMD5.0C (Texas Instruments) | Same 5.0V VRWM, 9.2V VC, but lower 400W PPK rating and no ISO7637-2 Pulse 3a validation | Limited to non-safety-critical 12V systems; lacks PPAP documentation and IATF 16949 traceability | Choose only for cost-sensitive non-automotive designs where full ISO7637-2 compliance is unnecessary |
Compared with SMBJ5.0C-13-F and TPSMD5.0C, SMBJ5.0CAQ-13-F uniquely delivers AEC-Q101 qualification, documented ISO7637-2 Pulse 3a (–220V) performance, and PPAP-ready manufacturing-making it the only option qualified for safety-relevant automotive ECUs requiring zero-defect reliability and full audit trail.

FAQ
Is SMBJ5.0CAQ-13-F unidirectional or bidirectional?
SMBJ5.0CAQ-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 constraints, making it ideal for differential buses like CAN and LIN where voltage swings occur in both directions.
What is the maximum clamping voltage under real-world surge conditions?
The maximum clamping voltage is 9.2V measured at 65.2A peak pulse current using the standardized 10×1000μs waveform per IEC 61000-4-5. This value is guaranteed across –55°C to +125°C ambient and remains stable under repeated surges when operated within derated power limits per Figure 6.
Does this TVS require a heatsink in automotive applications?
No heatsink is required. The SMBJ5.0CAQ-13-F is rated for 5.0W steady-state power dissipation at TL = +75°C with standard PCB copper land patterns. Its thermal resistance (junction-to-lead) enables direct mounting on 1oz copper pads meeting the suggested pad layout in DS40740 Rev. 15–2, page 5.
How does SMBJ5.0CAQ-13-F differ from standard SMBJ5.0A?
SMBJ5.0CAQ-13-F adds AEC-Q101 qualification, PPAP capability, IATF 16949 manufacturing, and explicit ISO7637-2 Pulse 3a (–220V) validation-features absent in the commercial SMBJ5.0A variant. The "AQ" suffix denotes automotive qualification, not just packaging or marking differences.
