Product details
Overview
SMCJ100AQ-13-F from Diodes Incorporated is a unidirectional 1500W automotive-grade 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 power-line circuits in engine control units, body electronics, and ADAS sensors against ISO7637-2 Pulse 1/2a/3a/3b surges and ISO10605 ESD events.
For engineers reviewing the SMCJ100AQ-13-F datasheet, SMCJ100AQ-13-F pinout, SMCJ100AQ-13-F application, or SMCJ100AQ-13-F equivalent, key selection criteria include clamping voltage margin vs. system rail, IPP derating above +25°C ambient, unidirectional polarity for DC-biased lines, and SMC package thermal performance under pulsed surge conditions.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal bias (VRWM = 100V), leakage remains ≤0.5µA; during transients, it avalanches at VBR = 111–123V (IT = 1.0mA) and clamps to ≤162V at IPP = 9.3A (10×1000µs waveform). Its response time is <1.0ps, enabling suppression of fast-rising ESD and load-dump edges.
Thermally, it sustains 5.0W steady-state dissipation at TL = +75°C and derates linearly to zero at TL = +175°C. Junction temperature range is –55°C to +175°C, supporting under-hood deployment without external heatsinking for single-event surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single 10×1000µs surges per ISO7637-2 without failure |
| Reverse Standoff Voltage | 100V - blocks system rail up to 100V DC; safe margin below 12V/24V automotive nominal rails |
| Clamping Voltage | 162V @ 9.3A - limits transient voltage seen by downstream ICs during ISO7637-2 Pulse 1 (–100V) |
| Breakdown Voltage | 111–123V @ 1.0mA - defines precise avalanche onset; tight 10.9% tolerance ensures predictable turn-on |
| Leakage Current | ≤0.5µA @ 100V - negligible standby power loss in always-on vehicle networks |
| Operating Temperature | –55°C to +175°C - qualified for engine bay, transmission, and brake module mounting locations |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic (UL 94V-0), 0.21g weight, cathode band polarity indicator. Moisture sensitivity level 1 (J-STD-020).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge return path | Connected to ground or low-impedance chassis; completes clamping loop during transient |
| Cathode | Protected line connection | Connected to protected signal/power line (e.g., CAN_H, 12V supply); clamps to anode when overvoltage occurs |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use with PPAP capability and IATF 16949 manufacturing |
| ISO7637-2 & ISO10605 compliant | Meets full test requirements for Pulse 1 (–100V), Pulse 2a (+50V), Pulse 3a (–150V), Pulse 3b (+100V), and 30kV ESD |
| Lead-free & halogen-free | RoHS 3 compliant (2015/863/EU); <900ppm Br, <900ppm Cl, <1000ppm Sb |
| Fast response time | <1.0ps - suppresses ESD events before sensitive ICs experience latch-up or gate oxide damage |
Applications
| Engine Control Unit (ECU) Power Input | CAN FD Transceiver Protection |
|---|---|
Use Scenario: 12V battery feed to ECU main power regulator subjected to load dump (ISO7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between VIN and GND, clamping surges before LDO input. Use Value: 162V clamping ensures downstream 40V-rated input capacitors and 36V LDOs remain within safe operating area during –100V Pulse 1 and +100V Pulse 3b events. | Use Scenario: CAN_H and CAN_L lines in ADAS domain controller exposed to ESD during connector mating/unmating. IC Role / Device Role / Timing Role: One SMCJ100AQ-13-F per line (CAN_H–GND, CAN_L–GND), providing bidirectional protection via two unidirectional devices. Use Value: 0.5µA leakage avoids CAN bus bias current errors; 162V clamping prevents transceiver damage during 30kV contact discharge per ISO10605. |
| Body Control Module (BCM) LIN Bus | Electric Power Steering (EPS) Motor Driver Supply |
Use Scenario: LIN bus termination in door module subjected to cable discharge events and battery transients. IC Role / Device Role / Timing Role: Unidirectional TVS from LIN line to chassis ground, leveraging 100V standoff to tolerate 12V rail variations. Use Value: 111–123V breakdown ensures reliable conduction only during faults-no false triggering during 13.5V cold-crank or 14.4V charging conditions. | Use Scenario: 24V supply rail to EPS H-bridge driver IC exposed to inductive kickback from motor windings. IC Role / Device Role / Timing Role: TVS placed across motor driver VDD and GND to clamp flyback spikes during PWM switching. Use Value: 1500W peak power rating absorbs repetitive 10×1000µs spikes without thermal runaway; SMC package enables direct PCB mounting near driver IC. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC100-13-F | Same 100V VRWM, but 600W PPK; lower IPP (5.2A) and higher VC (170V) | Not suitable for ISO7637-2 Pulse 1 (–100V) where tighter clamping is required | Select only for cost-sensitive non-safety systems with lower surge severity |
| SMCJ100A-Q | Identical electrical specs, but Q suffix denotes automotive grade with full PPAP documentation; same SMC package | No functional difference-only traceability and compliance reporting depth differs | Prefer for Tier 1 OEM programs requiring full change control and audit-ready records |
Compared with SAC100-13-F, SMCJ100AQ-13-F delivers 2.5× higher surge energy handling and 8V lower clamping, critical for protecting 3.3V/5V CAN transceivers; versus SMCJ100A-Q, it adds explicit AEC-Q101 test report linkage and IATF 16949 lot traceability without electrical trade-offs.

FAQ
Is SMCJ100AQ-13-F unidirectional or bidirectional?
SMCJ100AQ-13-F is unidirectional, indicated by the absence of "C" in the part number (e.g., SMCJ100CAQ-13-F would be bidirectional). It features a cathode band marking and must be oriented with cathode toward the protected line and anode to ground for proper clamping operation.
What is the maximum allowable junction temperature during surge events?
The absolute maximum junction temperature is +175°C, and the device is rated for continuous operation across that full range. During a single 10×1000µs surge, junction temperature rise depends on thermal resistance (RθJA ≈ 60°C/W for SMC on 1-in² copper) and pulse energy; typical ΔTJ remains <40°C for 9.3A pulses, well within safe limits.
Does this TVS require a series current-limiting resistor?
No series resistor is required for transient suppression. The TVS is designed for direct parallel connection across protected lines. Adding series resistance degrades clamping response and may cause voltage overshoot; layout focus should instead be on minimizing trace inductance between TVS terminals and the protected node.
How does SMCJ100AQ-13-F differ from industrial-grade SMCJ100A-13-F?
SMCJ100AQ-13-F includes AEC-Q101 qualification testing (HTOL, TC, UHAST), PPAP documentation readiness, and manufacturing in IATF 16949-certified facilities. The industrial SMCJ100A-13-F lacks these automotive-specific validations and traceability controls, making it unsuitable for safety-critical vehicle systems.
