Product details
Overview
SMBJ10CAQ-13-F from Diodes Incorporated is a bi-directional 600W surface-mount transient voltage suppressor (TVS) designed for automotive circuit protection against ISO7637-2 pulses (Pulse 1: −150V; Pulse 2a: +112V; Pulse 3a: −220V; Pulse 3b: +150V) and ISO10605 ESD events (±30kV air/contact discharge). It features 10V reverse standoff voltage (VRWM), 17.0V max clamping voltage at 35.3A peak pulse current, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the SMBJ10CAQ-13-F datasheet, SMBJ10CAQ-13-F pinout, SMBJ10CAQ-13-F application, or SMBJ10CAQ-13-F equivalent, this device is selected for robust bidirectional surge suppression in 12V/24V automotive power networks where low clamping voltage, high IFSM (100A), and IATF 16949-manufactured traceability are critical.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling protection of differential signal lines or ungrounded power rails without polarity constraints. Its 10V VRWM ensures compatibility with nominal 12V automotive systems while maintaining margin above battery float voltage (≈14.4V).
Clamping performance is defined by a 10×1000μs waveform per REA standards, delivering 17.0V VC at IPP = 35.3A - a key parameter for limiting downstream IC stress during load dump or inductive switching transients. Thermal derating follows a linear 4.8W/°C slope above +25°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single transient surges up to 600W without failure under 10×1000μs waveform |
| Reverse Standoff Voltage (VRWM) | 10.0V - maximum continuous DC or RMS voltage before significant leakage; sets operating margin for 12V systems |
| Breakdown Voltage (VBR) | 11.1–12.3V @ IT = 1.0mA - onset of avalanche conduction; defines turn-on threshold tolerance band |
| Max Clamping Voltage (VC) | 17.0V @ IPP = 35.3A - peak voltage seen by protected circuit during worst-case surge; determines IC survivability |
| Peak Forward Surge Current (IFSM) | 100A @ 8.3ms half-sine - handles repetitive load-dump energy without bond-wire fusing |
| Operating Temperature | −55°C to +175°C - supports placement near engines or in junction boxes with extreme thermal cycling |
| Leakage Current (IR) | ≤0.5µA @ VRWM - negligible standby power loss and minimal impact on low-power sensor biasing |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, molded plastic body with UL 94V-0 flammability rating; moisture sensitivity level 1 per J-STD-020; 0.1g mass; matte tin-plated terminals solderable per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry terminal in forward bias | For uni-directional variants only; bi-directional SMBJ10CAQ has no functional anode/cathode distinction |
| Cathode (Pin 2) | Current exit terminal in forward bias | Marked by cathode band on uni-directional parts; absent on SMBJ10CAQ due to symmetrical bi-directional structure |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping architecture | Enables protection of floating or AC-coupled lines (e.g., CAN H/L, LIN bus) without ground reference dependency |
| AEC-Q101 qualification & PPAP capability | Validated for automotive production use with full change control, lot traceability, and IATF 16949 manufacturing compliance |
| 600W peak pulse power (10×1000μs) | Withstands severe load dump and alternator ripple events common in 12V/24V vehicle electrical systems |
| Low clamping ratio (VC/VBR ≈ 1.53) | Minimizes overvoltage stress on downstream components such as microcontrollers, transceivers, and sensors |
| Halogen- and antimony-free "Green" construction | Meets automotive environmental requirements: <900ppm Br, <900ppm Cl, <1000ppm Sb compounds |
Applications
| Automotive Body Control Module (BCM) | Infotainment System Power Input |
|---|---|
Use Scenario: Protects 12V supply rail feeding microcontroller, relays, and LED drivers from battery line transients during jump-start or alternator regulation faults. IC Role / Device Role / Timing Role: Bi-directional TVS placed directly at PCB entry point to clamp ±150V ISO7637-2 Pulse 3b surges before reaching LDOs and logic ICs. Use Value: 17.0V clamping limits voltage stress on 20V-rated input capacitors and 5V/3.3V regulators, preventing latch-up or gate oxide damage. |
Use Scenario: Shields USB-C PD port and display power inputs from ESD events during user interaction and cable hot-plug cycles. IC Role / Device Role / Timing Role: Bidirectional suppression on VBUS and CC lines compliant with ISO10605 ±30kV contact discharge testing. Use Value: Sub-1µA leakage at 10V VRWM avoids loading low-quiescent-current PMICs; fast response (<1ns) prevents ESD-induced reset or data corruption. |
| CAN FD Transceiver Interface | ADAS Camera Power Rail |
Use Scenario: Guards CAN_H and CAN_L differential pair against coupled transients induced by nearby solenoid switching or ignition noise. IC Role / Device Role / Timing Role: Symmetric bi-directional TVS placed across differential lines to maintain common-mode immunity while suppressing differential surges. Use Value: 10V VRWM aligns with CAN FD common-mode range (−2V to +7V), ensuring no false triggering during normal operation while clamping >15V spikes. |
Use Scenario: Secures 5V/3.3V camera module supply against load dump surges propagating through vehicle harnesses. IC Role / Device Role / Timing Role: Primary front-end TVS on camera ECU's input stage, rated for 100A IFSM to survive repeated engine cranking transients. Use Value: 175°C max junction temperature allows mounting near heat-generating image sensors without thermal derating penalties. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | Same electrical specs but lacks AEC-Q101 qualification and PPAP support; RoHS-compliant but not automotive-grade change control | Acceptable for industrial or consumer designs; unsuitable for OEM automotive BOMs requiring qualified parts | Select SMBJ10CAQ-13-F when full automotive documentation, lot traceability, and IATF 16949 sourcing are mandatory |
| TPSMA6L10A-Q1 | Lower 400W PPK rating; 17.5V VC @ 34A; same 10V VRWM; AEC-Q101 qualified but different package (SMA) | Higher thermal resistance in SMA vs SMB reduces power handling in high-density layouts | Choose SMBJ10CAQ-13-F for higher surge margin and superior thermal dissipation in space-constrained automotive PCBs |
Compared with SMBJ10CA and TPSMA6L10A-Q1, SMBJ10CAQ-13-F delivers verified 600W surge capacity in the thermally optimized SMB package, full automotive change control, and tighter clamping - making it the preferred choice for safety-critical 12V power rail protection where reliability and documentation rigor are non-negotiable.

FAQ
What does the 'Q' suffix signify in SMBJ10CAQ-13-F?
The 'Q' denotes AEC-Q101 qualification - confirming that the device has passed stress tests for automotive temperature cycling, humidity, mechanical shock, and accelerated life validation. It also signals PPAP capability and manufacturing in IATF 16949-certified facilities, distinguishing it from commercial-grade SMBJ10CA variants.
Is SMBJ10CAQ-13-F suitable for protecting CAN bus lines?
Yes - its bi-directional architecture, 10V VRWM, and 17.0V clamping voltage align with CAN FD common-mode voltage limits (−2V to +7V) and transient immunity requirements. It is commonly deployed across CAN_H/CAN_L pairs to suppress coupled ESD and ISO7637-2 pulses without disrupting differential signaling integrity.
How does SMBJ10CAQ-13-F handle repeated surge events?
It is rated for non-repetitive surges per JEDEC standards (max 4 pulses/minute at 8.3ms half-sine). For repetitive stress, thermal derating applies: power dissipation drops linearly at 4.8W/°C above +25°C ambient. At TL = +75°C, steady-state PM(AV) is 5.0W - sufficient for intermittent load-dump scenarios in engine control units.
What is the significance of the '13-F' suffix in the orderable part number?
'13' indicates tape-and-reel packaging with 3,000 units per reel; 'F' specifies lead-free, RoHS-compliant matte tin plating on terminals. This packaging format ensures compatibility with automated SMT assembly lines and meets automotive solderability requirements per MIL-STD-202, Method 208.
