Product details
Overview
SMBJ6.0AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 µs), and clamps to ≤10.3 V at 58.3 A peak surge current - ideal for protecting MOSFETs and ICs in industrial power supplies.
For engineers reviewing the SMBJ6.0AHM3_A/I datasheet, SMBJ6.0AHM3_A/I pinout, SMBJ6.0AHM3_A/I application, or SMBJ6.0AHM3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, halogen-free RoHS compliance (HM3 suffix), thermal resistance (RθJA = 100 °C/W), and junction temperature range (–55 °C to +150 °C).
Technical Context
This TVS diode operates as a voltage-clamping protection device in series with sensitive downstream circuitry. Its glass-passivated junction enables fast response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 µs transients at 0.01% duty cycle.
Designed for surface-mount assembly on standard PCB copper pads (0.2" × 0.2"), it meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow peak, and supports automotive-grade reliability via AEC-Q101 qualification (HM3 suffix denotes halogen-free + AEC-Q101).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0AHE3_A/I | Same electrical specs; RoHS-compliant but not halogen-free (E3 vs HM3); no AEC-Q101 qualification | Limited to commercial-grade industrial and consumer use; not approved for automotive under AEC-Q101 | Select when halogen-free or automotive qualification is not required; lower cost alternative |
| SMBJ6.0CAHM3_A/I | Bidirectional variant; same VWM (6.0 V), symmetric clamping in both polarities; slightly higher VC (10.5 V) | Required for AC-coupled or dual-polarity signal lines (e.g., RS-485, CAN FD); unsuitable for DC rail protection | Choose only for bidirectional protection needs; not interchangeable with SMBJ6.0AHM3_A/I in unidirectional circuits |
Compared with SMBJ6.0AHE3_A/I, SMBJ6.0AHM3_A/I adds halogen-free construction and AEC-Q101 qualification at identical clamping performance; versus SMBJ6.0CAHM3_A/I, it provides optimized unidirectional clamping with tighter VC but cannot protect AC signals.

FAQ
What is the clamping voltage of SMBJ6.0AHM3_A/I at its rated peak pulse current?
The SMBJ6.0AHM3_A/I clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 58.3 A under the standardized 10/1000 µs waveform. This value is measured across the device terminals during transient suppression and defines the upper voltage limit imposed on protected circuitry. The SMBJ6.0AHM3_A/I maintains this clamping performance across its specified operating temperature range.
Is SMBJ6.0AHM3_A/I suitable for automotive applications?
Yes, SMBJ6.0AHM3_A/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction validated for automotive use. It is specifically intended for body electronics, infotainment power rails, and sensor interfaces where transient immunity and long-term reliability under thermal cycling are critical. The SMBJ6.0AHM3_A/I meets the environmental and stress-test requirements defined in AEC-Q101 Rev D.
How does the HM3 suffix differ from E3 or HE3 in the SMBJ6.0A family?
The HM3 suffix on SMBJ6.0AHM3_A/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. In contrast, E3 indicates RoHS-compliant but non-halogen-free commercial grade, while HE3 adds AEC-Q101 qualification without halogen-free assurance. The SMBJ6.0AHM3_A/I uniquely combines all three attributes: automotive qualification, halogen-free materials, and RoHS compliance - verified per JESD201 Class 2 whisker testing and MSL Level 1 reflow rating.
What is the thermal resistance of SMBJ6.0AHM3_A/I, and how does it affect layout design?
The SMBJ6.0AHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" copper pads. This value guides PCB layout: increasing pad area or adding thermal vias reduces effective RθJA, allowing higher average power dissipation. For sustained surge duty cycles, designers must verify junction temperature stays below 150 °C using SMBJ6.0AHM3_A/I's derating curve (Fig. 2 in datasheet 88392).
Can SMBJ6.0AHM3_A/I be used in bidirectional signal protection?
No, SMBJ6.0AHM3_A/I is a unidirectional TVS diode and must not be used for bidirectional signal lines such as RS-485 or CAN. Its cathode band marking and asymmetric IV characteristics mean it conducts only in reverse bias - forward conduction would occur at ~0.7 V, disrupting signal integrity. For bidirectional protection, the SMBJ6.0CAHM3_A/I variant is specified, with symmetrical clamping in both polarities. Using SMBJ6.0AHM3_A/I in place of a bidirectional device risks failure or signal distortion.
