Product details
Overview
SM6T10AHM3_B/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in SMB (DO-214AA) package, featuring 10 V standoff voltage (VWM), 14.5 V clamping voltage (VC) at 41 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics against inductive switching transients.
For engineers reviewing the SM6T10AHM3_B/I datasheet, SM6T10AHM3_B/I pinout, SM6T10AHM3_B/I application, or SM6T10AHM3_B/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, halogen-free RoHS compliance, thermal resistance (RθJA = 100 °C/W), and junction temperature range (–65 °C to +150 °C).
Technical Context
The SM6T10AHM3_B/I uses a glass-passivated silicon junction for low leakage and stable breakdown behavior under repetitive transient stress. Its unidirectional configuration provides cathode-banded polarity control and integrates into DC-biased protection paths without reverse conduction.
Designed for PCB-level surge immunity per IEC 61000-4-5 (8/20 μs) and ISO 7637-2, it delivers 18.6 V clamping at 215 A (8/20 μs), with thermal derating above 25 °C per Fig. 2 and MSL Level 1 moisture sensitivity rating (peak reflow 260 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.55 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum system DC bias margin. |
| VBR min/max | 9.50 V / 10.5 V at 1.0 mA - Confirmed breakdown threshold ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 14.5 V at 41.0 A (10/1000 μs) - Clamping voltage limits downstream device stress during 600 W transient surges. |
| PPPM | 600 W - Peak pulse power handling capacity defines maximum energy absorption capability per transient event. |
| ID @ VWM | 10.0 μA - Reverse leakage current at standoff voltage ensures minimal quiescent power loss in always-on protection circuits. |
| TJ max | +150 °C - Maximum junction temperature enables operation in under-hood automotive and high-ambient industrial environments. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance informs heatsinking requirements on standard FR-4 PCB with 0.2" × 0.2" copper pads. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, AEC-Q101 qualified. Cathode indicated by molded band on case end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes clamping path during transient conduction. |

IC Role / Device Role / Timing Role: Cathode-connected to -48 V rail, anode to ground, providing reverse-polarity-safe clamping during brownout recovery. Use Value: Withstands 100 A non-repetitive forward surge (IFSM), ensuring survivability during repeated power-cycling events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same VWM (8.55 V) and VC (14.5 V), but SMA package (higher RθJA = 140 °C/W); not AEC-Q101 qualified. | Limited to commercial-grade consumer/industrial use; unsuitable for under-hood automotive deployment. | Select SMAJ10A only if cost sensitivity outweighs thermal and qualification requirements. |
| SMCJ10A | Higher PPPM (1500 W), same VWM/VC, but larger SMC package (DO-214AB); AEC-Q101 available in HM3 variant. | Used where higher surge margin is needed (e.g., alternator output lines), requiring PCB area increase and layout revision. | Choose SMCJ10A when system-level surge testing exceeds 600 W or when extended lifetime under repeated stress is critical. |
Compared with SMAJ10A and SMCJ10A, the SM6T10AHM3_B/I uniquely balances AEC-Q101 qualification, halogen-free compliance, SMB footprint, and 600 W capability-making it optimal for space-constrained automotive modules where regulatory validation and material compliance are mandatory.

FAQ
What is the polarity configuration of the SM6T10AHM3_B/I?
The SM6T10AHM3_B/I is a unidirectional transient voltage suppressor. Its cathode is marked by a molded band on the SMB package body, and it conducts only when the cathode is at a higher potential than the anode-making it suitable for DC-biased protection paths such as power rails and signal lines referenced to ground. This polarity ensures no conduction during normal reverse-bias operation.
Is the SM6T10AHM3_B/I qualified for automotive applications?
Yes, the SM6T10AHM3_B/I is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's SM6T datasheet (Rev. 09-Jan-2024, Doc. #88385). It meets stress test requirements including temperature cycling, high-temperature reverse bias, and ESD, making it suitable for under-hood and chassis-mounted automotive electronics.
What is the maximum clamping voltage of the SM6T10AHM3_B/I under standard test conditions?
The SM6T10AHM3_B/I has a maximum clamping voltage (VC) of 14.5 V at 41.0 A peak pulse current with a 10/1000 μs waveform, as specified in the Electrical Characteristics table. This value defines the upper voltage limit imposed on protected circuitry during standardized surge events and is measured at TA = 25 °C with recommended PCB pad layout.
Does the SM6T10AHM3_B/I meet halogen-free and RoHS requirements?
Yes, the SM6T10AHM3_B/I carries the HM3 suffix, indicating it is halogen-free and RoHS-compliant per JEDEC JS709E and EU Directive 2011/65/EU. The molding compound meets UL 94 V-0 flammability rating, and terminals are matte tin plated per J-STD-002 and JESD 22-B102 standards.
What is the thermal resistance of the SM6T10AHM3_B/I, and how does it affect PCB layout?
The SM6T10AHM3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes standard FR-4 board construction; reducing pad size or omitting thermal vias increases RθJA, potentially limiting power dissipation and requiring derating above 25 °C per Figure 2 in the datasheet.
