Product details
Overview
SMCJ6.0AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) in SMC (DO-214AB) package, designed for clamping voltage transients up to 1500 W peak pulse power with 10.3 V maximum clamping voltage at 145.6 A peak pulse current. It features 6.67–7.37 V breakdown voltage at 10 mA test current, 6.0 V stand-off voltage, and <1000 µA reverse leakage at VWM - deployed for protecting MOSFETs, ICs, and sensor signal lines in automotive and industrial power rails.
For engineers reviewing the SMCJ6.0AHE3_A/H datasheet, SMCJ6.0AHE3_A/H pinout, SMCJ6.0AHE3_A/H application, or SMCJ6.0AHE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 1500 W surge rating, thermal resistance of 75 °C/W (junction-to-ambient), and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ6.0AHE3_A/H uses a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD, lightning-induced surges, and inductive switching transients. Its unidirectional architecture provides cathode-banded polarity with defined forward conduction path and reverse clamping behavior.
Rated for -55 °C to +150 °C operating junction temperature, it meets MSL Level 1 per J-STD-020 (260 °C peak reflow), and its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards. The device is qualified to AEC-Q101 for automotive applications and carries RoHS-compliant, halogen-free material status under Vishay's HE3 suffix designation.

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 | Lower peak pulse power (400 W), SMA package (DO-214AC), higher RθJA (110 °C/W) | Suitable only for lower-energy transients (e.g., IEC 61000-4-2 ESD), not ISO 7637-2 load dump | Select when board space is constrained and surge energy is limited to ≤400 W |
| SMCJ6.0CAHE3_A/H | Bidirectional variant; same VBR, VC, and PPPM but symmetrical clamping in both polarities | Required for AC-coupled or floating signal lines where polarity reversal occurs (e.g., RS-485, CAN bus) | Choose for bidirectional protection needs; not interchangeable with SMCJ6.0AHE3_A/H due to polarity architecture |
Compared with SMAJ6.0AHE3/A, SMCJ6.0AHE3_A/H delivers 3.75× higher surge energy handling and better thermal performance; versus SMCJ6.0CAHE3_A/H, it offers optimized clamping for DC power rails but lacks reverse-polarity protection - making SMCJ6.0AHE3_A/H the preferred choice for unidirectional 6 V rail protection in AEC-Q101-compliant automotive modules.

FAQ
What is the maximum clamping voltage of the SMCJ6.0AHE3_A/H at its rated peak pulse current?
The SMCJ6.0AHE3_A/H has a maximum clamping voltage (VC) of 10.3 V at its rated peak pulse current (IPPM) of 145.6 A, measured using a 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet revision 09-Jan-2024 (Document Number: 88394) and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The SMCJ6.0AHE3_A/H maintains this clamping performance across its full operating temperature range when mounted per recommended pad layout.
Is the SMCJ6.0AHE3_A/H suitable for automotive applications?
Yes, the SMCJ6.0AHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use via its "HE3" suffix, indicating RoHS-compliant construction and qualification to stress-test requirements including temperature cycling, mechanical shock, and humidity testing. It is commonly deployed in engine control units, body control modules, and ADAS power supplies where sustained operation from -40 °C to +125 °C ambient and immunity to load dump transients are required - all validated for the SMCJ6.0AHE3_A/H in Vishay's official documentation.
What does the "_A/H" suffix mean in SMCJ6.0AHE3_A/H?
The "_A/H" suffix in SMCJ6.0AHE3_A/H indicates packaging configuration: "A" denotes the revision code (per Vishay's ordering nomenclature), and "H" specifies the preferred package code for 7-inch plastic tape-and-reel delivery with 850 units per reel. This matches the ordering information table in the SMCJ5.0A–SMCJ188CA datasheet (Document Number: 88394), where SMCJ6.0AHE3_A/H is listed with unit weight 0.211 g and delivery mode "7\" diameter plastic tape and reel". The SMCJ6.0AHE3_A/H is not a functional variant - electrical and thermal specs remain identical to base SMCJ6.0AHE3.
How does the SMCJ6.0AHE3_A/H compare to bidirectional TVS diodes like SMCJ6.0CAHE3_A/H?
The SMCJ6.0AHE3_A/H is unidirectional and clamps only positive transients relative to ground, with cathode marked for correct orientation; SMCJ6.0CAHE3_A/H is bidirectional and clamps both polarities symmetrically. Their breakdown voltages (6.67–7.37 V), clamping voltages (10.3 V), and peak pulse power (1500 W) are identical, but polarity architecture differs fundamentally. The SMCJ6.0AHE3_A/H is intended for DC power rail protection, whereas SMCJ6.0CAHE3_A/H suits AC or floating signal lines - they are not interchangeable without circuit redesign.
What is the thermal resistance of the SMCJ6.0AHE3_A/H, and how does it affect PCB layout?
The SMCJ6.0AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on minimum recommended 0.31″ × 0.31″ (8.0 mm × 8.0 mm) copper pads per terminal. This value directly dictates PCB copper area needed to maintain TJ ≤ 150 °C under sustained power dissipation. For example, at 6.5 W steady-state dissipation (PD), a 48.75 °C rise requires adequate copper pour and possible internal layers - underscoring why the SMCJ6.0AHE3_A/H demands verified thermal layout per Vishay's mechanical drawings to ensure reliability.
