Product details
Overview
SMB10J6.0AHE3_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 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 against inductive switching transients.
For engineers reviewing the SMB10J6.0AHE3_A/H datasheet, SMB10J6.0AHE3_A/H pinout, SMB10J6.0AHE3_A/H application, or SMB10J6.0AHE3_A/H equivalent, this page delivers verified electrical parameters, automotive-grade qualification status, thermal resistance data, clamping performance under standardized surge waveforms, and real-world design implications for PCB layout and system-level ESD/surge resilience.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds its breakdown threshold (6.67–7.37 V at 10 mA), it rapidly transitions to low-impedance conduction to divert surge energy away from downstream ICs. Its glass-passivated junction ensures stable leakage (<1000 µA at 6.0 V) and repeatable clamping behavior across temperature.
Designed for surface-mount automation, SMB10J6.0AHE3_A/H features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, meets MSL Level 1 (260 °C reflow peak), and delivers 72 °C/W junction-to-ambient thermal resistance on standard 5.0 mm × 5.0 mm copper pads - enabling robust thermal management in space-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 6.0 V - maximum continuous reverse operating voltage before significant leakage begins; sets minimum system operating margin. |
| Breakdown Voltage (VBR) | 6.67–7.37 V at 10 mA - precise voltage threshold triggering clamping action; tight tolerance supports predictable protection timing. |
| Clamping Voltage (VC) | 10.3 V at 97.1 A (10/1000 µs) - peak voltage seen by protected circuit during worst-case surge; defines maximum stress on downstream components. |
| Peak Pulse Power (PPPM) | 1000 W - energy-handling capacity under standardized 10/1000 µs waveform; enables protection against ISO 7637-2 Pulse 1/2a/5a transients. |
| Junction Temperature Range | -55 °C to +150 °C - supports operation in under-hood automotive environments without derating loss. |
| Thermal Resistance (RθJA) | 72 °C/W - quantifies self-heating under surge; requires ≥5.0 mm × 5.0 mm copper pad per terminal for rated performance. |
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 reliable solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / surge return path | Connected to ground or low-impedance reference; must be routed with minimal inductance to sustain clamping performance. |
| Cathode | Protected line connection | Connected to signal/power line requiring protection; color band identifies this terminal; reverse-biased during normal operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics use including engine control, ADAS sensors, and body electronics - ensures reliability over lifetime thermal cycling and vibration. |
| Glass-passivated junction | Eliminates moisture sensitivity and improves long-term parameter stability versus epoxy-passivated alternatives; critical for field-deployed systems. |
| Low incremental surge resistance | Enables tighter clamping voltage window (10.3 V at 97.1 A) - reduces voltage overshoot during fast-rising transients like load dump or relay bounce. |
| MSL Level 1 rating | Supports single-reflow assembly without preconditioning; compatible with standard SMT lines using 260 °C peak profile. |
Applications
| Automotive Sensor Protection | MOSFET Gate Driver Protection |
|---|---|

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/H | 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) where 1000 W capability is required. | Select SMB10J6.0AHE3_A/H when protecting against high-energy automotive transients; choose SMBJ6.0AHE3_A/H only for lower-energy consumer or industrial surges. |
| SMCJ6.0AHE3_A/H | Larger SMC (DO-214AB) package, same VWM and VC, higher PPPM (1500 W), higher RθJA (50 °C/W). | Requires more PCB area but offers greater surge margin; thermal performance depends on larger pad layout. | Choose SMB10J6.0AHE3_A/H for space-constrained automotive modules needing 1000 W in SMB; select SMCJ6.0AHE3_A/H only if board area allows and >1000 W headroom is needed. |
Compared with SMBJ6.0AHE3_A/H and SMCJ6.0AHE3_A/H, SMB10J6.0AHE3_A/H uniquely balances 1000 W surge capability, AEC-Q101 qualification, and SMB footprint - making it optimal for automotive signal-line protection where both space and energy rating are constrained.

FAQ
What is the clamping voltage of SMB10J6.0AHE3_A/H at its rated peak pulse current?
The SMB10J6.0AHE3_A/H has a maximum clamping voltage (VC) of 10.3 V at 97.1 A peak pulse current under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMB10J6.0AHE3_A/H maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C), ensuring consistent protection in automotive under-hood applications.
Is SMB10J6.0AHE3_A/H suitable for bidirectional signal line protection?
No, SMB10J6.0AHE3_A/H is a unidirectional TVS diode, intended for DC-biased lines such as power rails or single-ended signal paths referenced to ground. For bidirectional protection (e.g., USB, RS-485, or AC-coupled lines), Vishay offers the SMB8J6.0CAHE3_A/H variant with symmetrical breakdown and clamping in both polarities. Using SMB10J6.0AHE3_A/H on bidirectional lines would result in forward conduction during negative half-cycles, potentially damaging the device or disrupting signal integrity.
Does SMB10J6.0AHE3_A/H require derating at elevated ambient temperatures?
Yes, SMB10J6.0AHE3_A/H must be derated above TA = 25 °C per Figure 2 in the Vishay datasheet (Document Number: 88422). At 85 °C ambient, its peak pulse power drops to approximately 700 W, and at 125 °C, it falls to ~450 W. Designers must apply this derating when sizing the device for under-hood automotive locations or enclosed industrial enclosures, and ensure thermal pad layout (minimum 5.0 mm × 5.0 mm copper per terminal) is maintained to preserve RθJA = 72 °C/W performance.
What does the "HE3" suffix indicate in SMB10J6.0AHE3_A/H?
The "HE3" suffix in SMB10J6.0AHE3_A/H denotes RoHS-compliant construction with AEC-Q101 qualification - confirming that the SMB10J6.0AHE3_A/H meets automotive reliability standards for temperature cycling, humidity resistance, mechanical shock, and long-term parametric stability. This distinguishes it from commercial-grade variants (e.g., "E3") and halogen-free automotive versions ("HM3"), and assures suitability for safety-critical vehicle subsystems including ADAS, body control modules, and powertrain interfaces.
Can SMB10J6.0AHE3_A/H be used in place of SMBJ6.0AHE3_A/H without PCB changes?
No - although both SMB10J6.0AHE3_A/H and SMBJ6.0AHE3_A/H share the SMB (DO-214AA) package and identical pinout, SMB10J6.0AHE3_A/H has higher thermal mass and different internal construction optimized for 1000 W surges. Substituting it into an existing SMBJ layout may cause localized overheating due to mismatched thermal pad requirements: SMB10J6.0AHE3_A/H requires 5.0 mm × 5.0 mm copper pads per terminal for rated performance, whereas SMBJ6.0AHE3_A/H is typically validated on smaller pads. Always verify thermal simulation and surge testing before interchange.
