Product details
Overview
SMCJ58CAQ-13-F from Diodes Incorporated is a bidirectional 1,500W automotive transient voltage suppressor (TVS) diode in SMC package, with 58V reverse standoff voltage (VRWM), 93.6V max clamping voltage (VC) at 16A peak pulse current, and AEC-Q101 qualification for under-hood power line protection against ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD events.
For engineers reviewing the SMCJ58CAQ-13-F datasheet, SMCJ58CAQ-13-F pinout, SMCJ58CAQ-13-F application, or SMCJ58CAQ-13-F equivalent, this part supports high-reliability automotive surge suppression where precise clamping, fast response (<1 ns), and IATF 16949-manufactured consistency are required - especially in 12V/24V battery rail, LIN/CAN transceiver protection, and body control module input stages.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering consistent clamping during negative and positive transients without polarity dependency. Its glass-passivated junction ensures stable breakdown behavior and low leakage (≤5 µA @ VRWM) over temperature (-55°C to +150°C).
The device uses a 10/1000 µs double-exponential pulse waveform per REA definition, achieving 1,500W peak pulse power with 93.6V clamping at IPP = 16.0A. Thermal derating follows a defined curve: PM(AV) drops from 5.0W at TL = +75°C to zero at TL ≈ +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single high-energy surges per ISO7637-2 Pulse 3b without failure |
| Reverse Standoff Voltage (VRWM) | 58.0V - maximum continuous DC or RMS voltage before significant leakage begins |
| Max Clamping Voltage (VC) | 93.6V @ IPP = 16.0A - limits downstream IC voltage stress during 10/1000µs transients |
| Breakdown Voltage (VBR) | 64.4V–71.2V @ IT = 1.0mA - defines sharp avalanche onset for predictable turn-on |
| Leakage Current (IR) | ≤5.0 µA @ VRWM - minimizes standby power loss in always-on automotive modules |
| Operating Temperature | -55°C to +150°C - supports placement near engines, inverters, and other high-temp zones |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic UL 94V-0 housing, cathode band omitted (bidirectional configuration). Weight: 0.21 g. Moisture sensitivity level: MSL 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals behave identically; no polarity assignment required in PCB layout |
| Case / Body | Thermal mass & mechanical anchor | Provides primary heat dissipation path to PCB copper; requires ≥25 mm² thermal pad for rated PM(AV) |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified & PPAP capable | Validated for automotive production use with full change control and IATF 16949 traceability |
| Glass-passivated die construction | Ensures stable VBR and low IR drift over lifetime and thermal cycling |
| 1,500W peak pulse rating (10/1000µs) | Protects against worst-case ISO7637-2 Pulse 1 (-100V) and Pulse 3a (-150V) events |
| Fast response time (<1 ns) | Clamps before sensitive downstream logic or analog circuitry can be damaged |
| Halogen- and antimony-free "Green" design | Meets automotive environmental compliance: <900 ppm Br, <900 ppm Cl, <1000 ppm Sb |
Applications
| Engine Control Unit (ECU) Power Input | CAN Transceiver Protection |
|---|---|
Use Scenario: 12V battery rail feeding microcontroller, fuel injector drivers, and sensor interfaces in gasoline/diesel ECUs. IC Role / Device Role: Primary overvoltage clamp on main power entry point, placed upstream of DC-DC converters. Use Value: Limits transient excursions to ≤93.6V during load dump (ISO7637-2 Pulse 5a), preventing latch-up or burnout of 5V/3.3V regulators. |
Use Scenario: Bidirectional protection on CAN_H and CAN_L lines in vehicle networking nodes. IC Role / Device Role: Symmetric surge limiter absorbing ESD (±30kV contact/air) and coupled noise from adjacent power lines. Use Value: Maintains signal integrity by clamping common-mode transients without distorting differential CAN waveforms due to matched bidirectional VBR. |
| Body Control Module (BCM) LIN Bus | ADAS Camera Power Supply |
Use Scenario: 12V-to-5V buck converter input in door module, seat controller, or lighting ECU with LIN communication. IC Role / Device Role: Secondary surge guard after main fuse, protecting switching regulator ICs and LIN transceivers. Use Value: Withstands repetitive ISO7637-2 Pulse 3b (+100V) events during actuator switching, extending system MTBF. |
Use Scenario: Front-facing camera module powered from vehicle battery with long harness runs susceptible to inductive kickback. IC Role / Device Role: First-line defense on 12V input before EMI filter and DC-DC stage. Use Value: Survives 200A IFSM surge (8.3ms half-sine) from alternator ripple or relay bounce, avoiding field returns. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC58C-13-F | Same VRWM (58V), lower PPK (600W), smaller SOD-123FL package | Limited to low-energy ESD-only scenarios; not rated for ISO7637-2 Pulse 1/3a | Select only for space-constrained non-load-dump applications with verified low surge exposure |
| TPSMA6.8CA | Lower VRWM (6.8V), same SMC package, 600W PPK, non-automotive grade | Not AEC-Q101 qualified; lacks PPAP documentation and IATF 16949 traceability | Acceptable for industrial prototypes but unsuitable for Tier 1 automotive production BOMs |
Compared with SAC58C-13-F and TPSMA6.8CA, SMCJ58CAQ-13-F uniquely delivers 1,500W surge capacity, full ISO7637-2 compliance, and automotive-grade process control - making it the only choice for safety-critical 12V/24V power rail protection where regulatory validation is mandatory.

FAQ
What does the 'C' suffix in SMCJ58CAQ-13-F signify?
The 'C' denotes bidirectional configuration: the device clamps symmetrically for both positive and negative transients, with identical VBR and VC characteristics in either polarity. This eliminates polarity marking on PCB and simplifies layout for differential or AC-coupled lines like CAN or LIN buses.
Is SMCJ58CAQ-13-F suitable for 24V commercial vehicle applications?
Yes - its 58V VRWM provides appropriate margin above nominal 24V systems (typically 20–28V operating range), and its 93.6V clamping voltage remains safely below the 100V+ absolute maximum ratings of most 24V-rated power management ICs and microcontrollers used in trucks and off-highway equipment.
How does the SMC package compare thermally to SMA or SMB?
The SMC (DO-214AB) package offers ~30% higher thermal resistance to ambient than SMA (DO-214AC) and ~50% higher than SMB (DO-214AA), but its larger copper pad area enables superior board-level heat spreading. For 5.0W steady-state dissipation, Diodes specifies minimum 25 mm² thermal pad with 2+ thermal vias - a requirement not met by smaller packages at equivalent power levels.
Does SMCJ58CAQ-13-F require derating at elevated ambient temperatures?
Yes - its peak pulse power must be linearly derated above +25°C ambient, per Fig. 1 in DS40741. At +85°C ambient, PPK is reduced to ~75% of 1500W (≈1125W); at +125°C, it falls to ~40% (≈600W). Steady-state power (PM(AV)) also derates from 5.0W at TL = +75°C to zero at TL = +150°C, per Fig. 6.
