Product details
Overview
SMCJ6.0AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) in SMC (DO-214AB) package, featuring 6.67 V minimum and 7.37 V maximum breakdown voltage at 10 mA test current, 6.0 V stand-off voltage, 1500 W peak pulse power rating (10/1000 µs), and clamping voltage of 10.3 V at 145.6 A peak pulse current - deployed for robust overvoltage protection on DC power rails and I/O lines in automotive control modules.
For engineers reviewing the SMCJ6.0AHM3/I datasheet, SMCJ6.0AHM3/I pinout, SMCJ6.0AHM3/I application, or SMCJ6.0AHM3/I equivalent, key selection criteria include verified unidirectional polarity, M3 halogen-free RoHS compliance, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and junction temperature range (–55 °C to +150 °C).
Technical Context
This device operates as a clamping-type TVS diode with glass-passivated junction and low incremental surge resistance, enabling sub-nanosecond response to ESD and lightning-induced transients. Its unidirectional configuration provides forward conduction capability (VF = 3.5 V at 100 A) and reverse-biased transient suppression up to 1500 W.
Designed for automated SMT placement, it meets JESD 201 Class 2 whisker resistance, J-STD-020 MSL Level 1 (260 °C peak reflow), and UL 94 V-0 flammability requirements. The SMC package supports 0.31" × 0.31" copper pad layout per Vishay's recommended thermal design.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0AHE3/A | Same VBR, VWM, and PPPM; SMA package (smaller footprint, lower IPPM = 105 A, higher RθJA = 95 °C/W) | Limited to lower-energy transients; unsuitable for automotive load-dump scenarios requiring ≥145 A | Select when board space is constrained and surge energy is ≤750 W |
| SMCJ6.0A-E3/57T | Identical electrical specs and SMC package; differs only in packaging (E3 RoHS-compliant, non-halogen-free, no AEC-Q101 qualification) | Not approved for automotive under-hood use; acceptable for commercial/industrial applications without AEC-Q101 mandate | Select when halogen-free or automotive qualification is not required |
Compared with SMCJ6.0AHM3/I, SMAJ6.0AHE3/A trades surge capacity and thermal robustness for compact size, while SMCJ6.0A-E3/57T retains identical protection performance but lacks halogen-free and AEC-Q101 credentials - making SMCJ6.0AHM3/I the sole choice for space-constrained, high-reliability automotive deployments.

FAQ
What is the breakdown voltage tolerance of SMCJ6.0AHM3/I?
The SMCJ6.0AHM3/I has a guaranteed breakdown voltage range of 6.67 V to 7.37 V at 10 mA test current, corresponding to ±10.4% tolerance around the nominal 6.0 V stand-off rating. This tight VBR window ensures consistent clamping behavior across production lots and supports precise circuit margining in safety-critical designs using the SMCJ6.0AHM3/I.
Is SMCJ6.0AHM3/I suitable for bidirectional transient protection?
No, SMCJ6.0AHM3/I is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. It conducts only in reverse bias during overvoltage events and provides forward conduction (VF = 3.5 V at 100 A). For bidirectional protection, Vishay specifies part numbers ending in "CA", such as SMCJ6.0CA - the SMCJ6.0AHM3/I must not be substituted in AC-coupled or symmetrical surge paths.
Does SMCJ6.0AHM3/I meet automotive qualification standards?
Yes, SMCJ6.0AHM3/I carries AEC-Q101 qualification, confirmed by its HM3 suffix (halogen-free, RoHS-compliant, and AEC-Q101 qualified). This certification covers stress tests including HTGB, HTRB, TCT, and mechanical shock, validating its suitability for automotive powertrain, chassis, and body electronics where SMCJ6.0AHM3/I is deployed per manufacturer specification.
What is the maximum clamping voltage of SMCJ6.0AHM3/I under surge conditions?
The SMCJ6.0AHM3/I clamps to a maximum of 10.3 V when subjected to its rated 145.6 A peak pulse current (10/1000 µs waveform). This value is measured under standardized test conditions with 0.31" × 0.31" copper pads and defines the upper voltage limit imposed on protected circuits during worst-case transients - a critical parameter for ensuring downstream ICs remain within their absolute maximum ratings when using the SMCJ6.0AHM3/I.
How does the M3 suffix affect the environmental compliance of SMCJ6.0AHM3/I?
The M3 suffix on SMCJ6.0AHM3/I indicates halogen-free, RoHS-compliant construction per JEDEC JS709 and IPC-1752 standards, with bromine and chlorine content below 900 ppm each. Unlike E3 variants, M3 ensures full compliance with automotive OEM green material declarations and eliminates corrosive halogen emissions during PCB assembly or end-of-life recycling - a mandatory requirement for modern vehicle platforms using the SMCJ6.0AHM3/I.
