Product details
Overview
SMCJ130CAQ-13-F from Diodes Incorporated is a bi-directional 130V standoff, 1500W peak pulse power transient voltage suppressor (TVS) in SMC package, designed for automotive circuit protection against ISO7637-2 pulses (Pulse 1: −100V; Pulse 2a: +50V; Pulse 3a: −150V; Pulse 3b: +100V) and ISO10605 ESD (±30kV air/contact discharge). It clamps at 209V under 7.2A 10×1000μs surge and operates from −55°C to +175°C.
For engineers reviewing the SMCJ130CAQ-13-F datasheet, SMCJ130CAQ-13-F pinout, SMCJ130CAQ-13-F application, or SMCJ130CAQ-13-F equivalent, this AEC-Q101 qualified, PPAP-capable TVS delivers verified clamping performance, bi-directional surge immunity, and IATF 16949-manufactured traceability for automotive power line and signal line protection.
Technical Context
This bi-directional TVS diode uses silicon avalanche junction technology to provide symmetric clamping for both positive and negative transients without polarity dependency. Its 130V reverse standoff voltage (VRWM) ensures stable operation under nominal 12V/24V automotive bus conditions while allowing margin before breakdown.
It responds within <1 ps to fast-rising transients and sustains 200A non-repetitive forward surge current (IFSM) per 8.3ms half-sine waveform. Thermal design is supported by 5W steady-state power dissipation at TL = +75°C and full operational range from −55°C to +175°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - Handles severe ISO7637-2 Pulse 1 (−100V) and Pulse 3a (−150V) without failure |
| Reverse Standoff Voltage (VRWM) | 130V - Stable blocking during 24V automotive system operation with safety margin |
| Breakdown Voltage (VBR) | 144–159V @ IT = 1mA - Ensures reliable avalanche initiation before damaging overvoltage |
| Clamping Voltage (VC) | 209V @ IPP = 7.2A (10×1000μs) - Limits downstream voltage to safe level during surge |
| Leakage Current (IR) | ≤0.5µA @ VRWM - Negligible standby power loss and minimal impact on high-impedance circuits |
| Operating Temperature | −55°C to +175°C - Fully rated for under-hood engine control unit (ECU) and transmission control environments |

Key Features
| Feature | Design Value |
|---|---|
| 1500W Peak Pulse Power | Enables single-device protection against worst-case ISO7637-2 Pulse 1 and Pulse 3a in 24V systems |

| AEC-Q101 Qualification & PPAP Capability | Supports automotive production release with full change control, lot traceability, and IATF 16949 manufacturing |
| Low Clamping Ratio (VC/VBR ≈ 1.45) | Minimizes voltage overshoot during surge-critical for protecting 130V-rated CAN FD or LIN transceivers |
| Lead-Free, Halogen-Free, RoHS 3 Compliant | Meets global environmental mandates (<900ppm Br/Cl, <1000ppm Sb) without compromising surge robustness |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) LIN Bus |
|---|---|
Use Scenario: Protects 24V supply rail of diesel ECU against load dump and alternator ripple-induced transients per ISO7637-2 Pulse 1 and Pulse 3b. IC Role / Device Role / Timing Role: Primary bidirectional clamping device placed upstream of DC/DC converter input stage. Use Value: Clamps surge to ≤209V, preventing damage to 36V-rated input MOSFETs and enabling use of lower-voltage, cost-optimized power stages. |
Use Scenario: Shields LIN transceiver data lines from ESD events (ISO10605 ±30kV) and coupled noise from adjacent high-current wiring harnesses. IC Role / Device Role / Timing Role: Low-capacitance (≈100pF) bi-directional TVS placed directly at connector interface. Use Value: Maintains LIN signal integrity with <1ps response and no DC bias requirement-no impact on 19.2kbps timing budget. |
| Advanced Driver Assistance Systems (ADAS) Camera Power | Electric Power Steering (EPS) Motor Driver |
Use Scenario: Safeguards 12V camera module power input against ignition-induced transients and battery disconnection spikes in ADAS front-facing cameras. IC Role / Device Role / Timing Role: First-line transient suppression before LDO regulator and image sensor power domain. Use Value: Withstands 200A IFSM surge and operates up to +175°C-enables placement near hot engine bay mounting locations. |
Use Scenario: Protects H-bridge gate driver supply rails in EPS motor controllers subjected to inductive kickback and battery reversal faults. IC Role / Device Role / Timing Role: Bidirectional clamp across VDD and GND pins of three-phase gate driver ICs. Use Value: Symmetric clamping prevents latch-up during negative-going transients-eliminates need for separate reverse-polarity protection diodes. |
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 |
|---|---|---|---|
| SAC130-13-F | Same 130V VRWM, but 1000W PPK (vs. 1500W); higher VC = 220V @ 6.5A | Limited to less severe ISO7637-2 Pulse 2a/3b; not suitable for Pulse 1 (−100V) in 24V systems | Select only if system-level surge testing confirms margin below 1000W requirement |
| SMCJ130A-13-F | Unidirectional version; same VRWM/VC/PPK but requires correct polarity orientation | Cannot protect AC-coupled or floating differential signals; adds layout risk in high-volume automotive assembly | Use only where polarity is fixed and board space allows explicit cathode marking verification |
Compared with SAC130-13-F and SMCJ130A-13-F, SMCJ130CAQ-13-F uniquely combines 1500W surge capacity, bi-directional symmetry, and full AEC-Q101 qualification-making it the only drop-in solution for ISO7637-2 Pulse 1–compliant 24V power rail protection in safety-critical ECUs.

FAQ
What is the maximum clamping voltage of SMCJ130CAQ-13-F under standard test conditions?
The maximum clamping voltage (VC) is 209V when subjected to a 7.2A peak pulse current with a 10×1000μs waveform at TA = +25°C. This value is measured per REA-defined surge profile and guarantees predictable voltage limiting during real-world automotive transients such as load dump and inductive switching.
Is SMCJ130CAQ-13-F suitable for protecting CAN FD physical layer interfaces?
Yes-it provides bi-directional clamping at 209V with low leakage (<0.5µA) and typical capacitance of ~100pF at 50mV/1MHz, making it compatible with CAN FD's 2–5Mbps signaling. Its 130V VRWM avoids false triggering on 24V bus common-mode swings while maintaining margin against ISO7637-2 Pulse 3b (+100V) coupling.
Does this part require derating at elevated ambient temperatures?
Yes-peak pulse power must be linearly derated above +25°C ambient, following the curve in Figure 1 of DS40741. At +85°C ambient, PPK is reduced to ~85% of 1500W (≈1275W); at +125°C, it drops to ~55% (≈825W). Steady-state power dissipation also derates with lead temperature per Figure 6.
How is AEC-Q101 qualification validated for this TVS diode?
Validation includes high-temperature reverse bias (HTRB), temperature cycling (−55°C to +150°C, 1000 cycles), mechanical shock, and ESD testing per AEC-Q101-004 (HBM ≥8kV, CDM ≥1kV). All tests were performed on production lots manufactured in IATF 16949-certified facilities with full PPAP documentation available upon request.
