Product details
Overview
SMB8J10CAHE3_A/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on signal and power lines. It features a 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage (VC) at 10 A peak pulse current, and 800 W peak pulse power dissipation (10/1000 µs waveform), with AEC-Q101 qualification for automotive electronics.
For engineers reviewing the SMB8J10CAHE3_A/I datasheet, SMB8J10CAHE3_A/I pinout, SMB8J10CAHE3_A/I application, or SMB8J10CAHE3_A/I equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VWM = 1.7), AEC-Q101 qualification, and compatibility with automated SMT placement on PCBs requiring robust ESD and lightning surge immunity per IEC 61000-4-2/4-5.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within <1 ps to transients exceeding its reverse stand-off voltage (VWM = 10 V). Its bidirectional symmetry enables protection of AC-coupled or differential signal paths without polarity constraints.
The device uses a glass-passivated silicon junction optimized for low incremental surge resistance and stable breakdown behavior under repetitive 10/1000 µs surges. Thermal resistance (RθJL = 20 °C/W) and junction temperature rating (TJ max = 150 °C) support sustained operation in automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal swing range. |
| VBR min/max | 11.1 V / 12.3 V at IT = 1 mA - Verified breakdown threshold ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 17.0 V at 10 A - Clamping voltage limits downstream IC stress during 800 W transient surges (10/1000 µs). |
| PPPM | 800 W - Peak pulse power handling capacity determines survivability against IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | 1.0 µA - Ultra-low leakage preserves signal integrity and battery life in always-on sensor interfaces. |
| TJ max | +150 °C - Enables deployment in engine control units, ADAS modules, and other high-temperature automotive zones. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction terminals | No functional distinction between pins; either terminal serves as cathode or anode depending on transient polarity. |
| Cathode Band (absent) | Polarity indicator | Not present - confirms bidirectional construction; device mounts without orientation constraint. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including powertrain, body electronics, and ADAS systems per stress test requirements. |
| Low clamping ratio (VC/VWM = 1.7) | Minimizes voltage overshoot during surge events, protecting 12 V-rated logic and analog front-ends without derating margin loss. |
| MSL Level 1 (260 °C peak) | Enables standard lead-free reflow soldering without moisture sensitivity concerns or baking preconditioning. |
| Glass-passivated junction | Ensures long-term stability of breakdown voltage and leakage current across temperature and lifetime stress conditions. |
| UL 94 V-0 molding compound | Provides flame-retardant encapsulation required for automotive cabin and under-hood assemblies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CAHE3_A/I | Unidirectional variant with same VWM (10 V) but higher PPPM (1000 W); lacks bidirectional symmetry. | Requires polarity-aware layout; unsuitable for AC-coupled or differential bus protection. | Select when higher single-polarity surge margin is needed and circuit topology permits unidirectional placement. |
| SMCJ10CAHE3_A/I | Larger SMC (DO-214AB) package; identical electrical specs but 1500 W PPPM rating and lower RθJA (35 °C/W). | Occupies ~2.5× PCB area; better thermal performance but incompatible with dense automotive layouts. | Choose when thermal derating at elevated ambient temperatures (>105 °C) is critical and board space allows. |

FAQ
What is the clamping voltage of SMB8J10CAHE3_A/I at its rated peak pulse current?
The SMB8J10CAHE3_A/I exhibits a maximum clamping voltage (VC) of 17.0 V when subjected to its specified peak pulse current of 10 A using the 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and guarantees predictable voltage limiting during surge events, ensuring downstream 12 V logic remains within safe operating limits. The SMB8J10CAHE3_A/I datasheet confirms this parameter under "Electrical Characteristics" for bidirectional devices.
Is SMB8J10CAHE3_A/I suitable for automotive applications?
Yes, SMB8J10CAHE3_A/I is AEC-Q101 qualified and explicitly designated for automotive use via its HE3 suffix and ordering code. It undergoes stress testing for temperature cycling, high-temperature operating life, and mechanical shock, supporting deployment in engine control units, door modules, and ADAS sensors. The SMB8J10CAHE3_A/I meets MSL Level 1 for lead-free reflow and operates reliably from –55 °C to +150 °C junction temperature.
How does SMB8J10CAHE3_A/I differ from unidirectional SMBJ10CAHE3_A/I?
SMB8J10CAHE3_A/I is bidirectional with symmetrical clamping behavior on both polarities, whereas SMBJ10CAHE3_A/I is unidirectional and requires correct cathode orientation. The SMB8J10CAHE3_A/I has lower peak pulse power (800 W vs. 1000 W) and slightly higher clamping voltage at same current due to dual-junction architecture. This makes SMB8J10CAHE3_A/I ideal for AC-coupled buses like CAN or USB, while SMBJ10CAHE3_A/I suits DC power rail protection.
What is the leakage current specification for SMB8J10CAHE3_A/I at its stand-off voltage?
At its 10 V stand-off voltage (VWM), the SMB8J10CAHE3_A/I specifies a maximum reverse leakage current (ID) of 1.0 µA at 25 °C. This ultra-low leakage preserves signal fidelity in high-impedance sensor interfaces and minimizes quiescent power draw in battery-powered automotive modules. The value is verified per the "Electrical Characteristics" table in the Vishay SMB8J5.0CA–SMB8J40CA datasheet (Doc. #88422).
Does SMB8J10CAHE3_A/I require special PCB layout considerations?
Yes - the SMB8J10CAHE3_A/I should be mounted using the minimum recommended pad layout (0.2" × 0.2" copper pads per terminal) to achieve rated 800 W surge capability and thermal performance. Short, direct traces to protected nodes minimize inductance, and ground planes must be solid beneath the device. The SMB8J10CAHE3_A/I datasheet specifies these requirements in the "Mechanical Data" and "Thermal Characteristics" sections to ensure reliable clamping response.
