Product details
Overview
SMBJ100AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping fast-rising ESD and surge transients on power and signal lines. It features a 100 V stand-off voltage (VWM), 111–123 V breakdown voltage (VBR) at 1 mA, 162 V maximum clamping voltage (VC) at 3.7 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and telecom equipment.
For engineers reviewing the SMBJ100AHE3_A/H datasheet, SMBJ100AHE3_A/H pinout, SMBJ100AHE3_A/H application, or SMBJ100AHE3_A/H equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (–55 to +150 °C), and RoHS-compliant packaging details required for automotive-grade surge protection design-in.
Technical Context
This TVS diode operates as a voltage-clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (VBR), limiting transient energy to safe levels across protected circuit nodes. Its unidirectional polarity enables integration into DC-biased lines where forward conduction must be blocked except during surge events.
Designed for automated SMT assembly, it meets J-STD-020 MSL Level 1 (peak reflow ≤ 260 °C), has matte tin-plated leads compliant with JESD 22-B102, and exhibits low incremental surge resistance for stable clamping under repetitive 10/1000 µs pulses at 0.01% duty cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse operating voltage before clamping begins; defines upper limit of normal DC bias tolerance. |
| VBR (min/max) | 111 V / 123 V at IT = 1 mA - guaranteed avalanche initiation window; ensures predictable turn-on across production lots. |
| VC @ IPPM | 162 V at IPPM = 3.7 A - peak clamped voltage during 10/1000 µs surge; determines worst-case overvoltage seen by downstream ICs. |
| PPPM | 600 W - peak pulse power handling with 10/1000 µs waveform; supports robust protection against lightning-induced surges per IEC 61000-4-5. |
| TJ max. | +150 °C - maximum junction temperature; enables operation in under-hood automotive and high-ambient industrial environments. |
| RθJA | 100 °C/W - thermal resistance junction-to-ambient on standard 0.2" × 0.2" copper pads; informs derating requirements above TA = 25 °C. |
| AEC-Q101 | Qualified - certified for automotive electronics per stress test standard; validates reliability for engine control, body electronics, and ADAS modules. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with cathode band marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); terminals are matte tin-plated for solderability per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient voltage clamp anode connection | Connected to protected line; conducts avalanche current to ground during overvoltage events. |
| Anode | Reference/ground return path | Typically tied to system ground or low-impedance return plane; completes clamping current loop during surge. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables compliance with IEC 61000-4-5 Level 4 (4 kV surge) when properly laid out with low-inductance grounding. |
| AEC-Q101 qualified | Validated for automotive applications including powertrain and chassis modules requiring extended temperature and life-cycle reliability. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking; reduces manufacturing overhead in high-volume SMT lines. |
| Glass passivated junction | Improves long-term stability of VBR and leakage under thermal cycling and humidity exposure versus epoxy-passivated alternatives. |
| RoHS-compliant & halogen-free option | Meets EU RoHS Directive 2011/65/EU and JEDEC JS709E material restrictions for green electronics manufacturing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100AHM3_A/H | Halogen-free variant with identical electrical specs and AEC-Q101 qualification; same SMB package and pinout. | No functional difference; selected when halogen-free compliance is mandated by OEM environmental policy. | Direct drop-in replacement where RoHS + halogen-free material declaration is required. |
| SMCJ100AHE3_A/H | Same VWM/VBR/VC ratings but in larger SMC (DO-214AB) package; higher RθJA (60 °C/W) and 1500 W PPPM rating. | Better suited for high-energy surges (>1 kV) or higher ambient temperatures due to improved thermal dissipation. | Choose when PCB layout allows larger footprint and higher surge margin is needed beyond 600 W. |
Compared with SMBJ100AHE3_A/H, the HM3 variant offers identical protection performance with halogen-free materials, while the SMCJ100AHE3_A/H provides higher pulse power headroom and lower thermal resistance at the cost of increased board area.

FAQ
What is the maximum clamping voltage of SMBJ100AHE3_A/H under a 10/1000 µs surge?
The SMBJ100AHE3_A/H has a maximum clamping voltage (VC) of 162 V at a peak pulse current (IPPM) of 3.7 A with a 10/1000 µs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and defines the highest voltage imposed on protected circuitry during a defined surge event. The SMBJ100AHE3_A/H maintains this clamping performance across its rated junction temperature range.
Is SMBJ100AHE3_A/H qualified for automotive applications?
Yes, SMBJ100AHE3_A/H is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and accelerated life validation required for automotive electronics. This qualification covers both commercial and extended temperature operation (–55 °C to +150 °C), making SMBJ100AHE3_A/H suitable for use in engine control, body electronics, and ADAS subsystems.
What does the "HE3" suffix indicate in SMBJ100AHE3_A/H?
The "HE3" suffix in SMBJ100AHE3_A/H denotes a RoHS-compliant, AEC-Q101 qualified version with standard matte tin plating. The "H" indicates the packaging configuration (7" tape and reel, 750 units), while "E3" confirms compliance with EU RoHS Directive 2011/65/EU. This distinguishes it from non-automotive variants like SMBJ100A-E3 and halogen-free versions such as SMBJ100AHM3_A/H.
How does SMBJ100AHE3_A/H compare to bidirectional TVS diodes like SMBJ100CA?
SMBJ100AHE3_A/H is unidirectional and intended for DC-biased lines where forward conduction must be blocked; SMBJ100CA is bidirectional and used in AC-coupled or floating signal paths. The SMBJ100AHE3_A/H has a cathode band marking and conducts only in reverse avalanche, whereas SMBJ100CA has no polarity marking and clamps symmetrically in both directions. Their VWM and VC values differ accordingly.
What is the thermal resistance junction-to-ambient (RθJA) for SMBJ100AHE3_A/H?
The SMBJ100AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended pad layout (0.2" × 0.2" copper pads per terminal). This value is critical for derating calculations above TA = 25 °C and must be applied alongside Fig. 2 from the Vishay datasheet (Document Number: 88392) to determine safe operating current limits at elevated ambient temperatures.
