Product details
Overview
SMB10J8.0AHE3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on DC power rails and signal lines. It features 8.0 V stand-off voltage (VWM), 13.6 V clamping voltage (VC) at 50 A peak pulse current, 1000 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMB10J8.0AHE3_A/H datasheet, SMB10J8.0AHE3_A/H pinout, SMB10J8.0AHE3_A/H application, or SMB10J8.0AHE3_A/H equivalent, this device is selected for robust overvoltage protection in automotive ECUs, industrial sensor interfaces, and 12 V board-level power inputs where low-leakage (<1.0 µA at VWM) and fast response (<1 ns) are critical.
Technical Context
This TVS diode operates as a clamping-type protector with a silicon avalanche junction, activated when reverse voltage exceeds its 8.89–9.83 V breakdown range (VBR at 1.0 mA). Its low incremental surge resistance ensures stable clamping under repetitive transients, while glass-passivated chip construction enhances reliability and thermal stability up to 150 °C junction temperature.
The SMB10J8.0AHE3_A/H is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), supports automated SMT placement, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.0 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 8.89 V / 9.83 V - Breakdown occurs within this range at 1.0 mA test current, defining turn-on threshold |
| VC @ IPPM | 13.6 V at 50 A - Clamped voltage during 10/1000 µs surge, limiting downstream IC stress |
| PPPM | 1000 W - Peak pulse power handling capability under standardized surge waveform |
| IPPM | 50 A - Maximum non-repetitive peak pulse current it can safely divert |
| ID @ VWM | <1.0 µA - Ultra-low reverse leakage preserves battery life and signal integrity in always-on circuits |
| TJ max | +150 °C - Enables operation in under-hood automotive environments and high-power industrial enclosures |

Applications
| Automotive Body Control Module (BCM) | Industrial CAN Transceiver Protection |
|---|---|
Use Scenario: Protecting 12 V power input of BCM microcontrollers and driver ICs against load-dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between fused battery rail and local DC/DC input. Use Value: Limits voltage to ≤13.6 V during 1000 W surges, preventing latch-up or gate oxide damage in downstream PMICs and MCUs. | Use Scenario: Safeguarding CANH/CANL differential pair inputs of isolated transceivers in factory automation nodes. IC Role / Device Role / Timing Role: Bidirectional-capable variant not used here; SMB10J8.0AHE3_A/H serves as single-line clamp on VCC supply feeding transceiver. Use Value: Suppresses ESD (IEC 61000-4-2) and burst noise (IEC 61000-4-4) on power rail without adding capacitance that degrades 1 Mbps CAN signal integrity. |

Use Scenario: Securing 5–12 V input of MEMS pressure/temperature sensors in harsh outdoor deployments. IC Role / Device Role / Timing Role: Primary overvoltage clamp upstream of LDO regulator, sized for 50 A surge margin. Use Value: Withstands repeated 10/1000 µs lightning-induced surges per IEC 61000-4-5 Level 3 (1 kV), ensuring >10-year field reliability. | Use Scenario: Protecting +28 V bias supply feeding GaN power amplifiers in 5G RRU power stages. IC Role / Device Role / Timing Role: Secondary surge limiter after bulk MOV, providing precise clamping where MOV let-through exceeds amplifier tolerance. Use Value: Delivers 13.6 V clamping at 50 A with <1 ns response-critical for preventing catastrophic failure of sensitive RF front-end components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A-E3/52 | Same SMB package, identical VWM/VC/PPPM, but commercial-grade (non-AEC-Q101) | Lacks automotive qualification; unsuitable for under-hood or safety-critical modules | Select only for cost-sensitive consumer or industrial applications without automotive reliability requirements |
| SMCJ8.0AHE3_A/H | Same AEC-Q101 rating and electrical specs, but larger SMC (DO-214AB) package (7.11 mm × 6.22 mm) | Higher thermal mass allows higher surge repetition rate; requires larger PCB footprint | Choose when system-level surge duty cycle exceeds SMB10J8.0AHE3_A/H derating limits or when board space permits larger package |
Compared with SMBJ8.0A-E3/52 and SMCJ8.0AHE3_A/H, the SMB10J8.0AHE3_A/H uniquely balances AEC-Q101 compliance, compact SMB footprint, and full 1000 W surge capability-making it optimal for space-constrained automotive modules requiring zero compromise on qualification or performance.

FAQ
What is the clamping voltage of SMB10J8.0AHE3_A/H at its rated peak pulse current?
The SMB10J8.0AHE3_A/H has a maximum clamping voltage (VC) of 13.6 V when subjected to its rated peak pulse current of 50 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees predictable overvoltage limiting for downstream circuitry, making SMB10J8.0AHE3_A/H suitable for protecting 12 V automotive electronics without exceeding safe voltage thresholds.
Is SMB10J8.0AHE3_A/H qualified for automotive applications?
Yes, SMB10J8.0AHE3_A/H is explicitly AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HE3". This qualification covers stress tests including temperature cycling, high-temperature operating life, and ESD robustness-ensuring SMB10J8.0AHE3_A/H meets reliability requirements for under-hood and chassis-mounted automotive modules.
What does the "HE3" suffix in SMB10J8.0AHE3_A/H indicate?
The "HE3" suffix in SMB10J8.0AHE3_A/H denotes RoHS-compliant construction with AEC-Q101 qualification, distinguishing it from commercial-grade variants (e.g., "E3") and halogen-free versions (e.g., "HM3"). The "_A/H" further specifies tape-and-reel packaging (7″ reel, 750 units) and revision level "A", confirming SMB10J8.0AHE3_A/H is a production-ready, automotive-qualified part with controlled manufacturing traceability.
Can SMB10J8.0AHE3_A/H be used in bidirectional protection circuits?
No-SMB10J8.0AHE3_A/H is a unidirectional TVS diode, intended for DC line protection with defined anode/cathode polarity. For bidirectional AC or differential signal protection, Vishay offers the SMB8J8.0CA family (e.g., SMB8J8.0CAHE3_A/H), which shares the same VWM and VC but uses symmetrical breakdown characteristics. Using SMB10J8.0AHE3_A/H in bidirectional roles risks improper clamping or failure.
What is the maximum operating junction temperature for SMB10J8.0AHE3_A/H?
The SMB10J8.0AHE3_A/H has a maximum operating junction temperature (TJ) of +150 °C, enabling reliable operation in high-ambient environments such as engine compartments or sealed industrial enclosures. This rating is supported by its typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and validated derating curves in the Vishay datasheet, ensuring SMB10J8.0AHE3_A/H maintains clamping performance across its full specified temperature range.
