Product details
Overview
SMAJ130CAQ-13-F from Diodes Incorporated is a bi-directional 400W automotive transient voltage suppressor (TVS) diode with 130V reverse standoff voltage, 209V max clamping voltage at 1.9A peak pulse current, and AEC-Q101 qualification for under-hood power line protection in ISO7637-2 Pulse 1/2a/3a/3b-compliant systems.
For engineers reviewing the SMAJ130CAQ-13-F datasheet, SMAJ130CAQ-13-F pinout, SMAJ130CAQ-13-F application, or SMAJ130CAQ-13-F equivalent, key selection criteria include clamping voltage margin vs. system rail, IPP derating above +25°C, bi-directional surge handling for AC-coupled or dual-polarity lines, and IATF 16949 manufacturing traceability.
Technical Context
This bi-directional TVS uses glass-passivated junction construction to achieve fast response (<1 ps) to transients while maintaining low leakage (<0.5 µA at 130V) and stable breakdown (144–159V at 1.0 mA). It operates across –55°C to +175°C junction temperature, supporting engine bay and transmission control unit deployments.
The device complies with ISO10605 ESD (±30kV air/contact) and ISO7637-2 automotive surge waveforms - including –100V Pulse 1, +50V Pulse 2a, –150V Pulse 3a, and +100V Pulse 3b - with 400W non-repetitive peak pulse power dissipation per 10×1000 µs waveform.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400W - sustains single 10×1000 µs surges without failure in automotive load-dump or inductive switching events |
| Reverse Standoff Voltage (VRWM) | 130V - maximum continuous DC or RMS voltage before significant leakage; sets minimum system operating margin |
| Max Clamping Voltage (VC) | 209V @ IPP = 1.9A - limits transient voltage seen by downstream ICs during ISO7637-2 Pulse 3a (–150V) |
| Breakdown Voltage (VBR) | 144–159V @ IT = 1.0mA - defines sharp avalanche onset; ensures predictable turn-on within 10% tolerance |
| Leakage Current (IR) | <0.5 µA @ VRWM - negligible standby power loss and no interference with high-impedance sensor bias networks |
| Operating Temperature | –55°C to +175°C - supports placement near engines, alternators, or power inverters without thermal derating |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, molded plastic UL 94V-0 housing; cathode band omitted (bi-directional configuration); moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 / Cathode 1 | Bi-directional surge terminal | Either terminal serves as anode or cathode depending on transient polarity; symmetrical clamping in both directions |
| Anode 2 / Cathode 2 | Bi-directional surge terminal | Paired with Terminal 1 to form bidirectional clamp path; no polarity marking required |
Key Features
| Feature | Design Value |
|---|---|
| 400W peak pulse rating | Enables protection of 12V/24V/48V automotive power rails against ISO7637-2 Pulse 1 (–100V) and Pulse 3a (–150V) without external series impedance |
| AEC-Q101 qualified | Validated for automotive use with HTOL, TC, UHAST, and ESD testing per stress test plan - required for ECUs, ADAS modules, and body controllers |
| Glass-passivated die | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift in under-hood environments |
| Lead-free & halogen-free | Meets RoHS 3 (2015/863/EU) and automotive green standards (<900ppm Br, <900ppm Cl, <1000ppm Sb) for end-of-life compliance |
Applications
| Engine Control Unit (ECU) Power Input | Automotive Infotainment Display Interface |
|---|---|
|
Use Scenario: Protects 12V main supply input of engine control units exposed to load dump (ISO7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role: Primary bidirectional clamping device placed directly at connector entry point before bulk capacitance and L-C filtering. Use Value: Limits transient voltage to ≤209V, preventing latch-up or gate oxide damage in MCU power management ICs rated for 220V absolute maximum. |
Use Scenario: Shields LVDS or FPD-Link III video interface lines between head unit and TFT display from ESD events during assembly and service. IC Role / Device Role: Low-capacitance bi-directional TVS placed differential-pair-wise across each signal pair (CLK+/–, DATA+/–). Use Value: Adds <0.5 µA leakage at 130V standoff, preserving signal integrity while meeting ISO10605 ±30kV contact discharge requirements. |
| Electric Power Steering (EPS) Motor Driver | Body Control Module (BCM) CAN Transceiver Line |
|
Use Scenario: Guards H-bridge gate driver supply rails against inductive kickback from 48V EPS motor windings during PWM commutation. IC Role / Device Role: Secondary surge suppression stage after primary TVS, placed adjacent to gate driver ICs to limit localized overshoot. Use Value: Clamps 1.9A pulses within 209V, keeping driver VDD below 220V rating and avoiding internal overvoltage shutdown. |
Use Scenario: Protects isolated CAN FD transceiver supply pins (VIO, VCC) from battery transients coupled through shared ground paths in BCM chassis mounting. IC Role / Device Role: Bi-directional clamping element on transceiver auxiliary supply lines where polarity reversal may occur during jump-start or battery disconnect. Use Value: Symmetrical 130V standoff and 209V clamping ensure equal protection for positive and negative surges without polarity-sensitive layout constraints. |
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 |
|---|---|---|---|
| SMAJ130A-13-F | Uni-directional; includes cathode band; same VRWM/VC/PPK but asymmetric conduction | Requires correct polarity orientation; unsuitable for AC-coupled or floating-bus lines | Select only when protecting unidirectional DC rails with known polarity and no risk of reverse voltage exposure |
| SMCJ130CA | Same VRWM/VC but higher PPK (1500W); DO-214AB package (larger footprint, higher thermal mass) | Supports longer-duration surges (e.g., extended load dump); requires PCB area increase (~2.5× SMA) | Choose when system-level testing reveals insufficient margin with 400W rating or when board space permits larger package |
Compared with SMAJ130A-13-F, the SMAJ130CAQ-13-F eliminates polarity dependency for mixed-signal or floating-ground interfaces; versus SMCJ130CA, it trades peak power headroom for compactness and cost efficiency in space-constrained ECU modules.

FAQ
What is the maximum clamping voltage of SMAJ130CAQ-13-F and at what test condition is it specified?
The maximum clamping voltage is 209V, measured at a peak pulse current (IPP) of 1.9A using the standardized 10×1000 µs double-exponential waveform per Figure 4 in DS40739 Rev. 17-2. This value is guaranteed across the full operating temperature range (–55°C to +175°C) and defines the upper voltage limit imposed on protected circuitry during surge events.
Is SMAJ130CAQ-13-F suitable for protecting CAN FD physical layer circuits?
Yes - its bi-directional architecture, 130V standoff, and 209V clamping provide symmetrical protection for CAN FD transceiver VCC and common-mode lines subject to battery transients. Its <0.5 µA leakage at VRWM avoids loading high-impedance bias networks, and AEC-Q101 qualification ensures reliability in vehicle network nodes.
How does the "AQ" suffix impact manufacturing and compliance for SMAJ130CAQ-13-F?
The "AQ" suffix denotes AEC-Q101 qualification, PPAP capability, and production in IATF 16949-certified facilities. It confirms full automotive change control, lot-level traceability, and adherence to Diodes' automotive quality management system - distinguishing it from commercial-grade SMAJ130CA-13-F variants lacking these certifications.
Can SMAJ130CAQ-13-F replace SMAJ130A-13-F in an existing design without layout changes?
No - SMAJ130CAQ-13-F is bi-directional and lacks a cathode band, while SMAJ130A-13-F is uni-directional with polarity marking. Substitution requires verification that the protected circuit has no polarity-dependent behavior (e.g., DC-biased rails) and that layout accommodates symmetric terminal routing without grounding conflicts.
