Product details
Overview
SM6S10ATHE3/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for automotive load dump protection. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR), 4600 W peak pulse power (10/1000 μs), 175 °C junction temperature rating, and DO-218AC package with anode-heatsink polarity.
For engineers reviewing the SM6S10ATHE3/I datasheet, SM6S10ATHE3/I pinout, SM6S10ATHE3/I application, or SM6S10ATHE3/I equivalent, this device serves as a high-reliability, AEC-Q101-qualified TVS for inductive switching surge suppression in 12 V automotive power systems where ISO 7637-2 compliance and MSL Level 1 solderability are required.
Technical Context
The SM6S10ATHE3/I employs passivated anisotropic rectifier technology to deliver low leakage current (<15 μA at VWM) and low forward voltage drop (≤1.9 V at 100 A), enabling efficient clamping during fast transients. Its thermal resistance (RθJC = 0.95 °C/W) supports stable operation up to TJ = 175 °C under sustained surge conditions.
It is optimized for unidirectional operation with heatsink-connected anode configuration and meets ISO 7637-2 load dump waveforms (10 ms exponential), making it suitable for engine control units, body control modules, and infotainment power rails where high-energy, low-clamping-voltage protection is critical.

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 and DO-218AC package; HM3 suffix indicates halogen-free, RoHS-compliant construction with different plating process | No functional difference in circuit behavior; HM3 variant replaces HE3 in new designs per Vishay's "Not For New Designs" notice | Select SM6S10AHM3 for new automotive designs requiring updated material compliance and long-term obsolescence mitigation |
| SMAJ10A | Lower PPPM (400 W), SMA package (RθJC ≈ 40 °C/W), VBR 11.1–12.3 V, same unidirectional polarity | Not suitable for load dump; limited to lower-energy transients like ESD or relay bounce; requires larger board area for thermal relief | Use SMAJ10A only in cost-sensitive, non-automotive applications where 4600 W surge immunity is not required |
Compared with SM6S10AHM3, the SM6S10ATHE3/I offers identical protection performance but lacks halogen-free certification and newer plating; compared with SMAJ10A, it delivers 11.5× higher surge power and superior thermal management-critical for under-hood automotive deployment.

FAQ
What is the maximum clamping voltage of the SM6S10ATHE3/I at rated peak pulse current?
The SM6S10ATHE3/I has a maximum clamping voltage (VC) of 17.0 V when subjected to its rated peak pulse current of 271 A using the 10/1000 μs waveform. This value is measured per standard test conditions in the Vishay datasheet (Document Number 87735) and defines the upper voltage limit imposed on protected circuits during surge events. Maintaining VC below 17.0 V ensures compatibility with 12 V automotive electronics that require headroom above nominal rail voltage.
Is the SM6S10ATHE3/I suitable for new automotive designs?
No-the SM6S10ATHE3/I is marked "Not For New Designs" in the official Vishay datasheet, with SM6S10AHM3 recommended as the replacement. While SM6S10ATHE3/I remains fully functional and AEC-Q101 qualified, new projects should use SM6S10AHM3 to ensure long-term supply continuity and compliance with updated material requirements. Existing designs may continue using SM6S10ATHE3/I under controlled obsolescence management.
How is the anode terminal configured on the SM6S10ATHE3/I DO-218AC package?
The anode terminal of the SM6S10ATHE3/I is integrated into the metal heatsink base of the DO-218AC package and must be soldered directly to a large PCB copper pour for optimal thermal performance. The cathode is the leaded terminal. This anode-heatsink configuration is confirmed in the mechanical drawings and polarity note of the Vishay datasheet, and is essential for achieving the specified RθJC of 0.95 °C/W.
Does the SM6S10ATHE3/I meet ISO 7637-2 requirements?
Yes-the SM6S10ATHE3/I is explicitly stated to meet ISO 7637-2 surge specifications under defined test conditions, particularly for Pulse 5a (load dump). Its 4600 W peak pulse power rating and 10 ms exponential waveform capability align with the energy demands of automotive load dump events. Compliance is verified per Vishay's characterization data in Document Number 87735, Figure 2.
What is the leakage current specification for SM6S10ATHE3/I at its stand-off voltage?
At its 10 V stand-off voltage (VWM), the SM6S10ATHE3/I exhibits a maximum reverse leakage current (ID) of 15 μA at 25 °C, rising to ≤250 μA at TJ = 175 °C. This low leakage ensures minimal impact on battery drain in always-on automotive modules and is validated per the Electrical Characteristics table in the Vishay datasheet (Document Number 87735).
