Product details
Overview
SMCJ100CAQ-13-F from Diodes Incorporated is a bi-directional 1500W automotive transient voltage suppressor (TVS) diode with 100V reverse standoff voltage, 162V max clamping voltage at 9.3A peak pulse current, and AEC-Q101 qualification. It protects CAN, LIN, and sensor interfaces in engine control units and body electronics against ISO7637-2 Pulse 1 (–100V), Pulse 3a (–150V), and ISO10605 ESD (±30kV).
For engineers reviewing the SMCJ100CAQ-13-F datasheet, SMCJ100CAQ-13-F pinout, SMCJ100CAQ-13-F application, or SMCJ100CAQ-13-F equivalent, this device is selected for high-energy surge immunity in 12V/24V automotive power domains where bidirectional clamping, low leakage (<0.5µA @ 100V), and IATF 16949-manufactured traceability are required.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or floating signal lines without polarity constraints. Its 10×1000µs waveform response delivers 162V clamping at 9.3A while maintaining sub-1ns response time to transients.
Designed for automotive-grade reliability, it sustains –55°C to +175°C junction operation and meets ISO7637-2 Pulse 1 (–100V), Pulse 3a (–150V), and ISO10605 ±30kV ESD requirements - verified under AEC-Q101 stress testing including HTGB, HTRB, and TCT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - handles ISO7637-2 Pulse 1/3a surges without thermal runaway |
| Reverse Standoff Voltage (VRWM) | 100V - sets minimum operating voltage before clamping activates in both directions |
| Max Clamping Voltage (VC) | 162V @ 9.3A - limits downstream IC stress during 10×1000µs transients |
| Breakdown Voltage (VBR) | 111–123V @ 1mA - ensures precise, repeatable turn-on threshold |
| Leakage Current (IR) | <0.5µA @ 100V - avoids parasitic loading on 100V bias rails or sensor references |
| Operating Temperature | –55°C to +175°C - supports under-hood placement in ECUs and ADAS modules |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic (UL 94V-0), 0.21g weight, cathode band omitted (bi-directional symmetry).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal (negative polarity) | Accepts reverse surge energy when voltage falls below –100V; forms symmetrical clamp path |
| Cathode | Current entry terminal (positive polarity) | Accepts reverse surge energy when voltage exceeds +100V; completes bidirectional conduction path |
Key Features
| Feature | Design Value |
|---|---|
| 1500W peak pulse rating | Enables single-device protection against worst-case ISO7637-2 Pulse 1 (–100V) and Pulse 3a (–150V) without derating |
| AEC-Q101 qualified | Validated for automotive use via HTGB, HTRB, and temperature cycling - no additional qualification needed for Tier 1 BOMs |
| IATF 16949 manufacturing | Ensures full traceability, PPAP documentation, and change control for OEM production programs |
| Bi-directional clamping | Protects AC-coupled buses (e.g., CAN FD differential pairs) without polarity-sensitive layout constraints |
Applications
| Engine Control Unit (ECU) Power Input | CAN FD Transceiver Protection |
|---|---|
|
Use Scenario: 12V battery feed to microcontroller power supply in gasoline/diesel ECUs exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main VBAT rail upstream of DC/DC converter. Use Value: Limits transient excursions to ≤162V, preventing damage to 3.3V/5V LDOs and MCU VDD pins during ISO7637-2 Pulse 1 (–100V) events. |
Use Scenario: Differential protection of CAN FD bus lines (CANH/CANL) in vehicle domain controllers. IC Role / Device Role / Timing Role: Bi-directional surge limiter placed across CANH–CANL pair near connector. Use Value: Clamps ±150V transients (ISO7637-2 Pulse 3a/b) while preserving signal integrity via low capacitance (<100pF) and fast sub-1ns response. |
| Body Control Module (BCM) Sensor Interface | ADAS Camera Power Line |
|
Use Scenario: Protection of LIN bus or analog sensor inputs (e.g., ambient temperature, rain sensor) in BCMs. IC Role / Device Role / Timing Role: Low-leakage (0.5µA) standoff clamp on 12V sensor supply line. Use Value: Maintains accuracy of millivolt-level sensor signals by avoiding DC loading while suppressing ISO10605 ±30kV contact discharge. |
Use Scenario: 12V power input protection for 5MP camera modules mounted behind rearview mirror or grille. IC Role / Device Role / Timing Role: First-stage transient absorber before point-of-load regulator. Use Value: Withstands repeated load dump pulses (up to 200A IFSM) without degradation, ensuring camera uptime in stop-start cycles. |
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 |
|---|---|---|---|
| SAC100-13-F | Same 100V VRWM, but 1000W rating and 175V VC @ 8.5A | Limited to lower-energy ISO7637-2 Pulse 3b (+100V); not rated for Pulse 1 (–100V) | Select when cost sensitivity outweighs need for full ISO7637-2 compliance |
| TPSMA100CA | 100V VRWM, 1500W, but only AEC-Q200 qualified (not Q101) and no PPAP support | Acceptable for non-safety-critical infotainment power rails; excluded from ECU/ADAS BOMs | Choose only for non-automotive industrial designs requiring identical electrical specs |
Compared with SAC100-13-F and TPSMA100CA, SMCJ100CAQ-13-F uniquely combines full ISO7637-2 Pulse 1/3a immunity, AEC-Q101 validation, and PPAP-ready manufacturing - making it the sole option for safety-critical power rail protection in certified automotive ECUs.

FAQ
What does the "C" suffix in SMCJ100CAQ-13-F signify?
The "C" denotes bi-directional configuration: the device clamps symmetrically for both positive and negative transients, with identical 100V standoff and 162V clamping performance in either polarity. This eliminates polarity marking on PCB layout and enables protection of AC-coupled interfaces like CAN FD without orientation constraints.
Is SMCJ100CAQ-13-F compatible with lead-free reflow processes?
Yes - it features matte tin lead-free plating, qualified per J-STD-020 moisture sensitivity Level 1, and withstands standard Pb-free reflow profiles (peak 260°C). The SMC package's thermal mass allows uniform heating, and its UL 94V-0 molding compound resists delamination during multiple reflow cycles.
How does its 162V clamping voltage impact system-level design?
A 162V clamping voltage establishes the absolute maximum stress imposed on downstream components during ISO7637-2 Pulse 1 (–100V) or Pulse 3a (–150V) events. Designers must ensure all components on the protected rail - including DC/DC input capacitors and MOSFETs - have ≥200V VDS/VRMS ratings to maintain margin.
Can this TVS be used in 24V commercial vehicle systems?
Yes - its 100V VRWM provides appropriate headroom above nominal 24V system voltage (typically 27–28V during charging), and its –55°C to +175°C operating range covers extended commercial vehicle thermal environments. Derating curves confirm sustained 1500W capability up to +125°C ambient.
