Product details
Overview
SMB10J6.0AHE3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection with 1000 W peak pulse power (10/1000 μs), 6.0 V stand-off voltage, and 10.3 V clamping voltage at 97.1 A peak pulse current. It is AEC-Q101 qualified and used to protect automotive sensor signal lines and MOSFET gate drivers from inductive switching transients.
For engineers reviewing the SMB10J6.0AHE3_A/I datasheet, SMB10J6.0AHE3_A/I pinout, SMB10J6.0AHE3_A/I application, or SMB10J6.0AHE3_A/I equivalent, this page delivers verified electrical parameters, automotive-grade qualification status, thermal resistance data, clamping behavior under surge, and real-world use context for ESD and load-dump transient suppression in 12 V automotive systems.
Technical Context
This TVS diode operates as a unidirectional clamping device with a breakdown voltage range of 6.67–7.37 V at 10 mA test current and a maximum reverse leakage of 1000 μA at 6.0 V stand-off. Its low incremental surge resistance enables fast response (<1 ns) to transients while maintaining stable clamping up to 10.3 V at rated IPPM.
Designed for surface-mount assembly on 5.0 mm × 5.0 mm copper pads, it features glass-passivated junction construction, meets MSL level 1 per J-STD-020 (260 °C reflow peak), and achieves 150 °C max junction temperature - enabling reliable operation in under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 6.0 V - Maximum continuous reverse voltage before significant conduction begins; sets operating margin below breakdown in 12 V automotive systems. |
| Breakdown Voltage (VBR) | 6.67–7.37 V at 10 mA - Confirmed minimum/maximum threshold where device enters avalanche conduction during surge events. |
| Clamping Voltage (VC) | 10.3 V at 97.1 A IPPM - Peak voltage seen by protected circuit during full-rated 1000 W transient; ensures downstream ICs remain within safe absolute maximum ratings. |
| Peak Pulse Power (PPPM) | 1000 W (10/1000 μs) - Energy-handling capability sufficient for ISO 7637-2 Pulse 1 & 2a load-dump and inductive switch-off transients. |
| Junction-to-Ambient RθJA | 72 °C/W - Thermal resistance measured on standard 0.2" × 0.2" copper pads; informs board-level thermal design for sustained surge duty cycles. |
| AEC-Q101 Qualified | Yes - Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces per stress test requirements. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, molded plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-impedance return path; defines polarity for unidirectional clamping action. |
| Cathode | Protected line input terminal | Connected to signal/power line being safeguarded; avalanche conduction occurs from cathode to anode during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| 1000 W peak pulse power rating | Enables robust protection against severe automotive load-dump events without degradation across multiple surges. |
| AEC-Q101 qualification | Validates reliability for automotive under-hood deployment, including temperature cycling, humidity bias, and mechanical shock testing. |
| Glass passivated junction | Improves long-term stability and moisture resistance versus epoxy-passivated alternatives, critical for 15+ year vehicle lifetimes. |
| MSL Level 1 moisture sensitivity | Allows standard SMT reflow without baking; compatible with high-volume automated assembly lines using 260 °C peak profile. |
Applications
| Automotive Sensor Protection | Power Supply Input Clamping |
|---|---|

IC Role / Device Role / Timing Role: Unidirectional TVS on each CAN line referenced to ground, supplementing integrated bus transceiver protection. Use Value: Extends system-level surge withstand beyond ISO 16750-2 Level 4 by limiting common-mode transients to safe levels before reaching transceiver inputs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0AHE3_A/I | Same SMB package, identical VWM (6.0 V) and VC (10.3 V), but lower PPPM (600 W vs. 1000 W). | Not suitable for ISO 7637-2 Pulse 5a load-dump; limited to lower-energy transients like ESD or relay bounce. | Select only when surge energy requirements are ≤600 W and cost optimization is prioritized over headroom. |
| SMCJ6.0AHE3_A/I | Higher-power SMC (DO-214AB) package with same VWM and VC, but 1500 W PPPM and higher IPPM (143 A). | Requires larger PCB footprint and different pad layout; better suited for primary front-end protection in battery management systems. | Choose when system-level surge compliance requires >1000 W rating and board space permits larger SMC outline. |
Compared with SMBJ6.0AHE3_A/I and SMCJ6.0AHE3_A/I, SMB10J6.0AHE3_A/I uniquely balances 1000 W surge capacity with SMB footprint - making it optimal for space-constrained automotive ECUs needing certified AEC-Q101 performance without SMC-level board area penalty.
