Product details
Overview
SMCJ100AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 100 V stand-off voltage (VWM), 111–123 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), 9.3 A peak pulse current (IPPM), and clamps at ≤162 V under 10/1000 μs surge.
For engineers reviewing the SMCJ100AHM3_A/H datasheet, SMCJ100AHM3_A/H pinout, SMCJ100AHM3_A/H application, or SMCJ100AHM3_A/H equivalent, key selection considerations include its AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, 150 °C max junction temperature, low incremental surge resistance, and suitability for automotive power line and sensor interface protection where robust transient immunity and high-reliability packaging are required.
Technical Context
The SMCJ100AHM3_A/H operates as a unidirectional clamping device with glass-passivated junction and fast response time (<1 ns). Its breakdown occurs at 111–123 V (tested at 1 mA), with a maximum clamping voltage of 162 V at 9.3 A IPPM under standardized 10/1000 μs waveform conditions.
Thermally, it exhibits RθJA = 75 °C/W and RθJL = 15 °C/W, enabling effective heat dissipation when mounted on 8.0 mm × 8.0 mm copper pads per terminal. The device meets MSL level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100AHE3_A/H | Lower PPPM (600 W), smaller SMB package (DO-214AA), same VWM/VBR range. | Reduced surge margin; suitable only for lower-energy transients or space-constrained layouts. | Select when board area is critical and peak surge energy remains below 600 W. |
| SMCJ100AHE3_A/H | Same electrical specs but RoHS-compliant commercial grade (E3), not halogen-free or AEC-Q101 qualified. | Lacks automotive qualification and halogen-free certification; limited to industrial/commercial use. | Choose for cost-sensitive non-automotive designs where AEC-Q101 and halogen-free requirements do not apply. |
Compared with SMCJ100AHM3_A/H, SMBJ100AHE3_A/H trades surge robustness for compactness, while SMCJ100AHE3_A/H retains identical protection performance but omits automotive qualification and halogen-free materials-making SMCJ100AHM3_A/H the sole choice for AEC-Q101-compliant, environmentally regulated automotive systems.

FAQ
What is the clamping voltage of the SMCJ100AHM3_A/H under maximum rated surge current?
The SMCJ100AHM3_A/H clamps to a maximum of 162 V when subjected to its rated 9.3 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured at the device terminals with specified mounting conditions (0.31" × 0.31" copper pads), and represents the upper limit of voltage imposed on protected circuitry during worst-case transient events. The SMCJ100AHM3_A/H maintains this clamping performance consistently across its qualified temperature range.
Is the SMCJ100AHM3_A/H suitable for automotive applications?
Yes, the SMCJ100AHM3_A/H is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction validated for automotive use. It is specifically intended for under-hood and body electronics applications such as engine control modules, lighting drivers, and ADAS sensor interfaces where reliability under thermal cycling, vibration, and high-energy transients is essential. The SMCJ100AHM3_A/H meets all stress-test requirements defined in the AEC-Q101 standard.
What does the "HM3" suffix signify in SMCJ100AHM3_A/H?
The "HM3" suffix in SMCJ100AHM3_A/H denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. It distinguishes this variant from commercial-grade versions (e.g., E3) and confirms compliance with JEDEC JESD201 Class 2 whisker resistance, MSL Level 1 moisture sensitivity, and automotive reliability standards. The SMCJ100AHM3_A/H is certified for use in safety-critical automotive subsystems where material content and long-term stability are strictly controlled.
How does the SMCJ100AHM3_A/H compare to bidirectional TVS diodes like SMCJ100CA?
The SMCJ100AHM3_A/H is unidirectional and intended for DC line protection where polarity is fixed (e.g., +12 V supply rails), offering lower leakage and higher surge current capability in one direction. In contrast, SMCJ100CA is bidirectional and suited for AC or floating signal lines. The SMCJ100AHM3_A/H has a cathode band marking and conducts only in reverse breakdown, whereas SMCJ100CA lacks polarity marking and clamps symmetrically. Their VWM and PPPM ratings are identical, but functional use cases differ fundamentally.
What is the maximum operating temperature for the SMCJ100AHM3_A/H?
The SMCJ100AHM3_A/H has a maximum junction temperature (TJ max.) of +150 °C, allowing reliable operation in high-temperature environments such as automotive engine compartments or industrial motor drives. Its thermal resistance values-RθJA = 75 °C/W and RθJL = 15 °C/W-are specified under standard PCB mounting conditions (8.0 mm × 8.0 mm copper pads), enabling accurate thermal design for the SMCJ100AHM3_A/H in thermally demanding applications.
