Product details
Overview
SM6T6V8AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount TRANSZORB® transient voltage suppressor (TVS) in SMB (DO-214AA) package, with 6.45 V minimum breakdown voltage (VBR), 5.80 V stand-off voltage (VWM), 10.5 V maximum clamping voltage (VC) at 57 A peak pulse current, and 600 W peak pulse power rating per 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines against inductive switching transients in automotive and industrial electronics.
For engineers reviewing the SM6T6V8AHM3/I datasheet, SM6T6V8AHM3/I pinout, SM6T6V8AHM3/I application, or SM6T6V8AHM3/I equivalent, key selection considerations include its AEC-Q101 qualification (HM3 suffix), halogen-free RoHS compliance, 150 °C max junction temperature, low-inductance SMB package, and verified clamping performance under standardized surge waveforms.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-banded polarity, designed for fast response to transient overvoltages via avalanche breakdown. Its glass-passivated junction ensures stable leakage and robust surge handling, while the SMB package supports automated placement and meets MSL level 1 (260 °C reflow peak).
The SM6T6V8AHM3/I delivers precise voltage protection with 5.80 V stand-off capability and clamps to ≤10.5 V at 57 A (10/1000 μs), enabling reliable interface-level protection without affecting normal circuit operation - critical for 5 V rail protection in automotive control modules and industrial I/O circuits.

IC Role / Device Role / Timing Role: Low-capacitance TVS integrated directly at connector entry point to minimize stub length and preserve signal integrity. Use Value: Cathode-band orientation enables correct polarity alignment with sensor supply rails, ensuring clamping only during overvoltage conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/5B | Lower VWM (5.1 V), higher VC (10.8 V at 53.5 A), same SMB package but non-AEC-Q101 commercial grade | Not qualified for automotive use; suitable for consumer/industrial where AEC-Q101 is not mandated | Select when cost sensitivity outweighs automotive qualification requirement and 5.1 V standoff suffices |
| SM6T6V8AHE3_B/I | Identical electrical specs and SMB package, but RoHS-compliant commercial grade (E3) without halogen-free or AEC-Q101 qualification | Lacks automotive reliability validation; limited to non-safety-critical commercial applications | Choose for legacy designs requiring E3 suffix compatibility or where HM3-specific halogen-free compliance is unnecessary |
Compared with SM6T6V8AHM3/I, SMAJ6.0A-E3/5B offers lower cost but no automotive qualification, while SM6T6V8AHE3_B/I matches form/fit/function but omits AEC-Q101 and halogen-free certification - making SM6T6V8AHM3/I the sole choice for new automotive designs requiring both qualifications.

FAQ
What is the clamping voltage of SM6T6V8AHM3/I at its rated peak pulse current?
The SM6T6V8AHM3/I has a maximum clamping voltage (VC) of 10.5 V at 57 A peak pulse current using the standard 10/1000 μs waveform. This value is measured under defined test conditions per JEDEC standards and ensures downstream components experience controlled overvoltage stress during surge events. The SM6T6V8AHM3/I maintains this clamping performance across its specified operating temperature range.
Is SM6T6V8AHM3/I qualified for automotive applications?
Yes, SM6T6V8AHM3/I is AEC-Q101 qualified, as confirmed by the HM3 suffix in its ordering code. This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD, validating its suitability for automotive powertrain, chassis, and body electronics. The SM6T6V8AHM3/I meets the reliability requirements for under-hood and cabin-mounted modules.
What does the "HM3" suffix indicate in SM6T6V8AHM3/I?
The "HM3" suffix in SM6T6V8AHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this variant from commercial-grade versions (e.g., E3 or M3) and confirms compliance with automotive environmental and reliability standards. The SM6T6V8AHM3/I is intended for applications where both regulatory compliance and automotive-grade robustness are required.
What is the standoff voltage rating of SM6T6V8AHM3/I?
The SM6T6V8AHM3/I has a maximum reverse stand-off voltage (VWM) of 5.80 V, meaning it remains in high-impedance state below this voltage with leakage current ≤1000 μA. This rating allows safe integration into 5 V systems while providing sufficient margin above nominal rail voltage to avoid false triggering. The SM6T6V8AHM3/I's VWM is tightly controlled to ensure consistent protection behavior across production lots.
Which package type does SM6T6V8AHM3/I use, and what are its key mechanical features?
SM6T6V8AHM3/I uses the SMB (DO-214AA) surface-mount package: 2.20 mm × 3.94 mm body size, matte tin-plated leads compliant with J-STD-002 solderability, and UL 94 V-0 rated molding compound. Its low-profile design supports automated placement, and the cathode band provides unambiguous polarity identification. The SM6T6V8AHM3/I's SMB footprint is compatible with standard PCB pad layouts defined in Vishay's mechanical drawings.
