Product details
Overview
SMCJ100CA-M3/9AT from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 1500 W peak pulse power rating, 100 V standoff voltage, and 162 V clamping voltage at 9.3 A peak pulse current. It protects sensitive ICs, MOSFETs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMCJ100CA-M3/9AT datasheet, SMCJ100CA-M3/9AT pinout, SMCJ100CA-M3/9AT application, or SMCJ100CA-M3/9AT equivalent, key selection criteria include bidirectional clamping capability, 1500 W 10/1000 µs surge rating, 100 V working voltage, and halogen-free RoHS-compliant M3 termination.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within <1 ps to transients induced by inductive load switching or lightning surges. Its bidirectional architecture enables symmetrical clamping in both polarities without polarity marking, and its glass-passivated junction ensures stable breakdown behavior under repetitive surge stress.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it delivers 1500 W peak pulse power dissipation with thermal resistance of 75 °C/W (junction-to-ambient) and supports operating junction temperatures from –55 °C to +150 °C - meeting AEC-Q101 qualification when ordered with HE3/HM3 suffixes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 1500 W - sustains high-energy transients without failure in automotive and industrial environments |
| Standoff Voltage (VWM) | 100 V - maximum continuous reverse voltage before significant leakage begins |
| Clamping Voltage (VC @ IPPM) | 162 V at 9.3 A - limits downstream voltage during surge to protect 100 V-rated components |
| Breakdown Voltage (VBR min/max) | 111 V / 123 V at 1 mA - defines sharp avalanche onset region for precise overvoltage triggering |
| Leakage Current (ID @ VWM) | 1.0 µA - negligible standby power loss and minimal interference on protected signal lines |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height |
| Operating Temperature | –55 °C to +150 °C - supports under-hood automotive and high-temp industrial deployments |
Pinout & Package
SMCJ100CA-M3/9AT uses a two-terminal SMC (DO-214AB) package with no polarity marking due to its bidirectional construction. Terminals are matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker test requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional surge path | Either terminal serves as input/output for transient energy; no cathode band or polarity identification required |
| Case (body) | Thermal and mechanical interface | Non-conductive molded body provides UL 94 V-0 flammability rating and mechanical mounting stability |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| 1500 W peak pulse rating | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth, 2 kV line-line) in properly laid-out PCBs |
| Halogen-free & RoHS-compliant (M3) | Meets environmental compliance mandates for automotive and EU industrial equipment without compromising surge robustness |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (<1 ns response), improving protection margin |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking, simplifying SMT production flow |
Applications
| Automotive Power Distribution | Industrial Sensor Signal Lines |
|---|---|
Use Scenario: Protecting 12 V/24 V power rails in body control modules against load dump and alternator transients. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed upstream of DC-DC converters and microcontrollers. Use Value: Clamps 100 V rail surges to ≤162 V, preserving system uptime and avoiding brownout-induced resets in AEC-Q100-compliant ECUs. | Use Scenario: Safeguarding analog outputs (e.g., 4–20 mA, 0–10 V) of pressure/temperature sensors in factory automation PLCs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp on differential or single-ended sensor interfaces exposed to ESD and cable discharge events. Use Value: Limits transient excursions to <162 V while maintaining sub-µA leakage, preventing ADC saturation and measurement corruption. |
| Telecom Line Interface Protection | Consumer Appliance Motor Drive Circuits |

IC Role / Device Role / Timing Role: Primary-level surge suppression on data line pairs before secondary TVS or common-mode chokes. Use Value: Absorbs up to 1500 W of coupled surge energy without degradation, enabling compliance with ITU-T K.21 basic protection level. | Use Scenario: Guarding gate drivers and half-bridge MOSFETs in washing machine motor inverters from inductive kickback during commutation. IC Role / Device Role / Timing Role: Clamp diode across DC bus or phase leg to suppress >100 V switching spikes. Use Value: Prevents MOSFET avalanche failure and reduces electromagnetic emissions by limiting dv/dt during turn-off. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA-M3 | 600 W peak pulse power, SMB (DO-214AA) package, same VWM/VC but lower surge capacity | Suitable for lower-energy surges (e.g., IEC 61000-4-2 ESD only); not rated for IEC 61000-4-5 line surges | Select when board space is constrained and surge threat level is limited to ESD or low-energy transients |
| SMCJ100A-M3/9AT | Unidirectional version; includes cathode band marking and forward voltage drop (VF = 3.5 V @ 100 A) | Required where DC-biased circuits need asymmetric clamping (e.g., power supply inputs with defined polarity) | Choose only if circuit topology mandates unidirectional conduction or requires forward conduction capability |
Compared with SMBJ100CA-M3 and SMCJ100A-M3/9AT, the SMCJ100CA-M3/9AT uniquely combines bidirectional operation, 1500 W surge rating, and halogen-free compliance - making it optimal for high-reliability 100 V rail protection where polarity is undefined or alternating.

FAQ
What does the "CA" suffix indicate in SMCJ100CA-M3/9AT?
The "CA" suffix denotes a bidirectional configuration: SMCJ100CA-M3/9AT clamps voltage transients equally in both polarities, with no cathode marking on the SMC package. This distinguishes it from unidirectional variants like SMCJ100A-M3/9AT, which feature a cathode band and conduct forward current. The CA version is used where signal or power lines lack defined polarity, such as AC-coupled interfaces or floating buses.
How does the M3 suffix affect SMCJ100CA-M3/9AT compliance and performance?
The M3 suffix indicates halogen-free, RoHS-compliant construction with matte tin-plated leads meeting J-STD-002 and JESD 22-B102 solderability standards. It does not alter electrical performance versus E3-suffix parts but satisfies stricter environmental regulations in automotive and EU industrial markets. SMCJ100CA-M3/9AT retains identical 1500 W surge rating, 100 V VWM, and 162 V VC as its E3 counterpart.
Can SMCJ100CA-M3/9AT be used in place of SMCJ100A-M3/9AT?
No - SMCJ100CA-M3/9AT is bidirectional while SMCJ100A-M3/9AT is unidirectional with a defined cathode. Substituting them requires verifying circuit polarity: SMCJ100CA-M3/9AT may be used where polarity is undefined or alternating, but will not provide forward conduction capability. Reverse substitution risks incorrect clamping behavior and potential failure in AC or floating applications.
What is the recommended PCB layout for optimal surge performance of SMCJ100CA-M3/9AT?
Vishay specifies mounting SMCJ100CA-M3/9AT on minimum 0.31″ × 0.31″ (8.0 mm × 8.0 mm) copper pads per terminal to achieve rated 1500 W peak pulse power. Short, wide traces to ground/power planes minimize inductance, and symmetric layout ensures balanced current sharing. Avoid thermal reliefs on pads to maintain low thermal resistance (RθJA = 75 °C/W).
Is SMCJ100CA-M3/9AT qualified to AEC-Q101?
No - SMCJ100CA-M3/9AT carries the commercial-grade M3 suffix. AEC-Q101 qualification requires the HM3 suffix (e.g., SMCJ100CAHM3_A/I). While SMCJ100CA-M3/9AT shares identical electrical specs and SMC package, only HM3-suffix variants undergo extended stress testing per AEC-Q101. For automotive under-hood use, specify HM3 versions with appropriate revision code.
