Product details
Overview
SMBJ100CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. 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, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed across power rails and signal lines in industrial motor drives and telecom interface circuits.
For engineers reviewing the SMBJ100CAHE3_A/H datasheet, SMBJ100CAHE3_A/H pinout, SMBJ100CAHE3_A/H application, or SMBJ100CAHE3_A/H equivalent, this device serves as a RoHS-compliant, AEC-Q101-qualified bidirectional TVS for high-reliability surge suppression where precise clamping behavior, low leakage (<1 µA at VWM), and thermal stability up to +150 °C junction temperature are critical selection criteria.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, delivering consistent clamping performance without polarity dependency. Its glass-passivated junction ensures stable VBR tolerance (±5%), low incremental surge resistance, and fast response time (<1.0 ps) to transient events such as ESD, lightning-induced surges, and inductive switching spikes.
Thermally, it exhibits RθJA = 100 °C/W (typ.) and RθJL = 20 °C/W (typ.), enabling reliable operation under repetitive surge conditions when mounted on 0.2" × 0.2" copper pads. The device meets MSL Level 1 per J-STD-020 and supports lead-free reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - Maximum continuous reverse operating voltage before significant conduction begins; defines safe operating margin below clamping threshold. |
| VBR (min/max) | 111 V / 123 V at IT = 1 mA - Confirmed breakdown range ensures predictable turn-on during transients without premature triggering. |
| VC @ IPPM | 162 V at 3.7 A - Clamping voltage under 10/1000 µs surge defines worst-case voltage seen by protected circuitry. |
| PPPM | 600 W - Peak pulse power handling capacity determines survivability against standardized lightning/surge waveforms. |
| ID @ VWM | <1 µA - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss in high-impedance nodes. |
| TJ max. | +150 °C - Maximum junction temperature enables deployment in under-hood automotive and industrial environments. |
| Package | SMB (DO-214AA) - Low-profile SMT footprint (5.21 mm × 4.06 mm) compatible with automated placement and IPC-7351B land patterns. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Cathode/anode terminals are symmetrical; device functions identically regardless of orientation in PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (either end) | Transient return path (bidirectional) | Provides low-impedance shunt path to ground or rail during positive or negative voltage excursions beyond VBR. |
| Cathode (either end) | Transient return path (bidirectional) | Functionally identical to anode due to symmetrical construction; no cathode band marking on bidirectional variants. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables protection against IEC 61000-4-5 Level 4 surges (4 kV line-to-earth) without degradation under repetitive stress. |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive powertrain and body electronics applications requiring zero-failure reliability over extended temperature and lifetime cycles. |
| MSL Level 1, 260 °C reflow compatible | Supports standard lead-free SMT assembly without pre-baking or special handling, reducing manufacturing overhead. |
| Glass-passivated junction | Delivers stable VBR drift <0.1 %/°C and long-term parameter consistency across thermal cycling and humidity exposure. |
| RoHS-compliant, halogen-free option available | Meets EU RoHS Directive 2011/65/EU and JEDEC JS709E material requirements for environmentally constrained designs. |
Applications
| Industrial Motor Drives | Telecom Ethernet Interfaces |

IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp installed at RJ45 connector entry point to divert energy away from magnetics and PHY IC. Use Value: Maintains signal integrity with sub-1 µA leakage at 100 V, while clamping induced surges within IEEE 802.3af-compliant voltage limits. |
| Automotive Body Control Modules | Consumer Power Adapters |
|
Use Scenario: Input-stage protection for 12 V/24 V supply inputs subjected to load dump (ISO 7637-2 Pulse 5a) and jump-start transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp upstream of DC-DC converters and microcontrollers in BCMs. Use Value: Survives 600 W pulses with <10 ns response, meeting AEC-Q101 stress test requirements for automotive-grade durability. |
Use Scenario: Secondary-side output rail protection in universal-input AC/DC adapters powering USB-C PD or smart home devices. IC Role / Device Role / Timing Role: Final-stage TVS safeguarding downstream USB controllers and battery management ICs from output capacitor discharge spikes. Use Value: Provides 100 V stand-off margin above nominal 5–20 V outputs, ensuring no false triggering during normal regulation ripple. |
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-E3/52 | Same electrical specs, but commercial-grade (non-AEC-Q101), RoHS-compliant only; no automotive qualification. | Limited to industrial/commercial use; not approved for automotive ECUs or ADAS modules. | Select when cost sensitivity outweighs automotive qualification requirements and full temperature range validation is unnecessary. |
| SAC100CA | Higher VC (170 V @ 3.5 A), lower PPPM (400 W), same SMB package; SAC series uses different chip design with higher dynamic impedance. | Less effective clamping margin in high-current surge scenarios; suitable only for lower-energy transients. | Choose only if legacy SAC footprint compatibility is mandatory and system-level surge testing confirms 170 V clamping is acceptable. |
Compared with SMBJ100CA-E3/52, the SMBJ100CAHE3_A/H adds AEC-Q101 qualification and tighter process controls for automotive use; versus SAC100CA, it delivers superior 600 W surge handling and 9 V lower clamping voltage - directly improving protected IC survival rate in harsh environments.

FAQ
What is the clamping voltage of SMBJ100CAHE3_A/H at its rated peak pulse current?
The SMBJ100CAHE3_A/H has a maximum clamping voltage (VC) of 162 V at its specified peak pulse current (IPPM) of 3.7 A, measured using the standardized 10/1000 µs double-exponential surge waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is confirmed in Vishay's datasheet Document Number 88392, page 2.
Is SMBJ100CAHE3_A/H suitable for automotive applications?
Yes, SMBJ100CAHE3_A/H is AEC-Q101 qualified, as indicated by the "HE3" suffix, making it suitable for automotive applications including body control modules, infotainment power supplies, and sensor interface protection. Its operating junction temperature range of –55 °C to +150 °C and validated surge endurance meet stringent automotive reliability requirements per the specification sheet.
Does SMBJ100CAHE3_A/H have polarity markings on the package?
No, SMBJ100CAHE3_A/H is a bidirectional TVS diode and carries no cathode band or polarity marking on the SMB (DO-214AA) package. Its symmetrical construction allows installation in either orientation on the PCB without affecting electrical performance - a key advantage for layout flexibility and automated assembly.
What is the maximum reverse leakage current for SMBJ100CAHE3_A/H at its stand-off voltage?
The maximum reverse leakage current (ID) for SMBJ100CAHE3_A/H is 1.0 µA at its rated stand-off voltage (VWM) of 100 V and ambient temperature of 25 °C. This ultra-low leakage preserves signal fidelity and minimizes power loss in high-impedance monitoring or precision analog circuits protected by the SMBJ100CAHE3_A/H.
Can SMBJ100CAHE3_A/H be used in place of a unidirectional TVS like SMBJ100AHE3_A/H?
No - SMBJ100CAHE3_A/H is strictly bidirectional and cannot replace unidirectional variants such as SMBJ100AHE3_A/H in circuits requiring polarity-sensitive clamping (e.g., DC rail-to-ground protection). Substitution would eliminate intended forward conduction path functionality and compromise protection integrity; always verify circuit topology and transient directionality before selecting SMBJ100CAHE3_A/H.
