Product details
Overview
SM6S10AHE3/2D from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor in DO-218AB package, rated for 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown (VBR), 4600 W peak pulse power (10/1000 μs), 175 °C junction temperature, and AEC-Q101 qualified for automotive load dump protection.
For engineers reviewing the SM6S10AHE3/2D datasheet, SM6S10AHE3/2D pinout, SM6S10AHE3/2D application, or SM6S10AHE3/2D equivalent, key selection criteria include clamping voltage (17.0 V at IPPM), low leakage (<15 μA at VWM), unidirectional polarity, DO-218AB thermal performance (RθJM = 0.45 °C/W), and compliance with ISO7637-2 surge testing.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver high-temperature stability up to TJ = 175 °C and low forward voltage drop (VF ≤ 1.9 V at 100 A). Its DO-218AB package features a metal heatsink anode and matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102.
The device meets MSL Level 1 per J-STD-020 (peak reflow 245 °C) and is RoHS-compliant with HE3 suffix satisfying JESD 201 Class 2 whisker resistance. It is explicitly qualified to AEC-Q101 and categorized per Vishay's material compliance standard (doc?99912).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before conduction begins |
| VBR (min/typ/max) | 11.1 / 11.7 / 12.3 V at 5 mA - precise breakdown threshold enabling predictable clamping onset |
| VC @ IPPM | 17.0 V at 271 A (10/1000 μs) - low clamping voltage limits downstream IC stress during transients |
| PPPM (10/1000 μs) | 4600 W - high surge capacity suitable for automotive load dump per ISO7637-2 |
| ID @ VWM | <15 μA at 25 °C - minimal leakage preserves battery life in always-on automotive modules |
| TJ max. | 175 °C - enables placement near hot engine-control electronics without derating |
| RθJM | 0.45 °C/W - low junction-to-mount thermal resistance supports direct PCB copper pour heatsinking |
Pinout & Package
Package: DO-218AB - molded surface-mount case with integral metal heatsink (anode), UL 94 V-0 rated compound, and anode-side sprocket-hole orientation on 13″ tape.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Heatsink Tab) | Current entry point during clamping; thermal interface | Must be soldered to ≥200 mm² copper pour for RθJM = 0.45 °C/W; polarity reference for unidirectional operation |
| Cathode (Lead 1) | Current exit point during clamping; signal reference | Connected to protected line (e.g., 12 V rail); defines directionality - blocks reverse surge only |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated reliability for automotive under-hood applications including temperature cycling, HTRB, and ESD |
| Junction passivation | Stable VBR over lifetime and temperature; prevents parameter drift in harsh environments |
| ISO7637-2 compliance | Withstands load dump surges up to 35 V for 400 ms without degradation |
| MSL Level 1 rating | Compatible with standard SMT reflow profiles up to 245 °C peak without popcorn or delamination |
| Low VF (≤1.9 V) | Minimizes conduction loss during sustained overvoltage events, reducing thermal stress |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SM6S10AHM3 | Same electrical specs; HM3 suffix indicates halogen-free, Pb-free, and enhanced MSL1 robustness vs. HE3 | Preferred for new designs requiring full halogen-free compliance and extended reflow margin | Select SM6S10AHM3 when updating legacy designs or qualifying for next-gen automotive platforms with stricter material requirements |
| SMAJ10A | Lower PPPM (400 W), SMA package (RθJA = 110 °C/W), no AEC-Q101 qualification | Limited to non-automotive industrial or consumer applications with lower surge severity | Use SMAJ10A only in cost-sensitive, non-automotive contexts where 4600 W surge capacity and 175 °C operation are unnecessary |
Compared with SM6S10AHE3/2D, SM6S10AHM3 offers identical protection performance with improved environmental compliance, while SMAJ10A trades significant surge capacity and automotive qualification for lower cost and smaller footprint - making SM6S10AHE3/2D the optimal choice for AEC-Q101–mandated, high-energy load dump scenarios.

FAQ
What is the clamping voltage of SM6S10AHE3/2D at its rated peak pulse current?
The SM6S10AHE3/2D clamps to a maximum of 17.0 V at its specified peak pulse current of 271 A under the 10/1000 μs waveform. This value is guaranteed across temperature and ensures downstream circuitry remains within safe operating voltage limits during automotive load dump events. The SM6S10AHE3/2D achieves this with low dynamic impedance and optimized junction design.
Is SM6S10AHE3/2D suitable for new automotive designs?
No - the Vishay datasheet explicitly states "Not For New Designs" and recommends SM6S10AHM3 as the alternative. While SM6S10AHE3/2D remains fully functional and AEC-Q101 qualified, new designs should use the HM3 variant for updated halogen-free compliance and enhanced MSL1 robustness. SM6S10AHE3/2D continues to be supported for existing production programs.
What does the HE3 suffix mean on SM6S10AHE3/2D?
The HE3 suffix on SM6S10AHE3/2D indicates RoHS-compliant, lead-free termination with matte tin plating, AEC-Q101 qualification, and JESD 201 Class 2 whisker resistance. It also confirms compliance with Vishay's material categorization standard (doc?99912) and suitability for high-reliability automotive applications.
How is the anode terminal configured on SM6S10AHE3/2D?
On the SM6S10AHE3/2D in DO-218AB package, the metal heatsink tab is the anode terminal - it must be electrically connected to the protected line's positive side and thermally coupled to PCB copper for effective heat dissipation. Lead 1 (cathode) connects to the return path, establishing unidirectional surge conduction from cathode to anode during overvoltage events.
Does SM6S10AHE3/2D meet ISO7637-2 requirements?
Yes - the SM6S10AHE3/2D is specified to meet ISO7637-2 surge test requirements, particularly Pulse 5a (load dump), due to its 4600 W peak pulse power rating, 175 °C junction capability, and validated clamping behavior under 10/1000 μs and 10/10,000 μs waveforms. Test compliance is confirmed per the manufacturer's characterization data in Document 88384.
