Product details
Overview
SMBJ6.0AHM3/H 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 - used for protecting MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the SMBJ6.0AHM3/H datasheet, SMBJ6.0AHM3/H pinout, SMBJ6.0AHM3/H application, or SMBJ6.0AHM3/H equivalent, key selection criteria include unidirectional polarity, 10.3 V clamping voltage at rated IPPM, MSL Level 1 moisture sensitivity, halogen-free RoHS compliance (HM3 suffix), and AEC-Q101 qualification readiness via HM3_X variants.
Technical Context
This TVS diode operates as a fast-acting shunt protector: under normal conditions it presents high impedance (>1 MΩ leakage at 6.0 V), then avalanches within <1 ns when transient voltage exceeds VBR, diverting surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance.
Designed for automated SMT assembly, it mounts on 5.0 mm × 5.0 mm copper pads per terminal and achieves thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead). The cathode band denotes polarity; no marking is used for bidirectional variants.

Use Scenario: Guarding -48 V telecom power feed inputs against lightning-induced surges and hot-swap transients. IC Role / Device Role / Timing Role: Used in series with higher-voltage TVS or MOVs in multi-stage protection networks for central office equipment. Use Value: Provides precise low-voltage clamping stage with fast response, reducing stress on downstream Zener or thyristor-based protectors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A-E3/52 | Same electrical specs; RoHS-compliant but not halogen-free; commercial grade only (no AEC-Q101 path) | Lacks halogen-free certification and automotive qualification roadmap | Select when cost sensitivity outweighs material compliance or automotive qualification needs |
| SAC5.0 | Lower 5.0 V VWM, 600 W rating, but SOD-123 package (smaller footprint, lower thermal mass) | Higher thermal impedance limits sustained surge handling; unsuitable for high-repetition-rate industrial transients | Choose only for space-constrained consumer designs where 5 V rail margin allows tighter clamping |
Compared with SMBJ6.0A-E3/52, SMBJ6.0AHM3/H adds halogen-free compliance and AEC-Q101 qualification readiness; compared with SAC5.0, it offers superior thermal performance and higher surge current handling in SMB package - critical for industrial and automotive deployments requiring long-term reliability.

FAQ
What is the maximum clamping voltage of SMBJ6.0AHM3/H at its rated peak pulse current?
The SMBJ6.0AHM3/H has a maximum clamping voltage (VC) of 10.3 V when subjected to its rated peak pulse current (IPPM) of 58.3 A using the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring compatibility with 5 V logic families and microcontroller I/O tolerances. The SMBJ6.0AHM3/H maintains this clamping performance across its full operating temperature range.
Does SMBJ6.0AHM3/H meet automotive qualification standards?
The SMBJ6.0AHM3/H itself is not AEC-Q101 qualified, but its HM3 suffix indicates halogen-free, RoHS-compliant construction and qualifies it for the AEC-Q101 qualification path via HM3_X revision codes (e.g., HM3_B/H). Vishay documents that HM3-base parts support AEC-Q101 testing per the "base P/NHM3_X" designation in the ordering information table. Therefore, SMBJ6.0AHM3/H serves as the commercial-grade foundation for automotive-grade variants.
How does the SMBJ6.0AHM3/H differ from bidirectional SMBJ6.0CA variants?
The SMBJ6.0AHM3/H is unidirectional, with polarity marked by a cathode band and intended for DC line protection where reverse voltage blocking is required. In contrast, SMBJ6.0CA is bidirectional, has no polarity marking, and provides symmetrical clamping for AC-coupled or floating signal lines. Their VBR and VC values differ: SMBJ6.0CA has higher VBR (min 6.8 V) and VC (11.2 V), while SMBJ6.0AHM3/H delivers tighter 10.3 V clamping - making it preferable for 5 V DC rail protection where lower clamping is essential.
What is the thermal resistance of SMBJ6.0AHM3/H, and how does it affect layout design?
The SMBJ6.0AHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This means PCB layout must allocate sufficient copper area to each pad to maintain junction temperature below +150 °C under worst-case surge repetition. Reducing pad size increases RθJA, risking thermal runaway during repetitive transients - so SMBJ6.0AHM3/H requires adherence to Vishay's recommended mounting pad layout.
Is SMBJ6.0AHM3/H compatible with lead-free reflow processes?
Yes, SMBJ6.0AHM3/H is rated for MSL Level 1 per J-STD-020 with a maximum peak reflow temperature of 260 °C, making it fully compatible with standard lead-free (SnAgCu) reflow profiles. Its matte tin-plated terminals meet J-STD-002 and JESD 22-B102 solderability requirements, and the device undergoes JESD 201 Class 2 whisker testing - confirming robustness in high-volume automated SMT assembly without pre-baking or special handling.
