Product details
Overview
SMBJ6.0AHM3_B/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping fast-rising ESD and surge 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 MOSFET gates, microcontroller I/O, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the SMBJ6.0AHM3_B/H datasheet, SMBJ6.0AHM3_B/H pinout, SMBJ6.0AHM3_B/H application, or SMBJ6.0AHM3_B/H equivalent, key selection criteria include unidirectional polarity, 10.3 V clamping voltage at rated IPPM, AEC-Q101 qualification status (via HM3 suffix), MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device: under normal conditions it presents high impedance (>1 MΩ leakage at 6.0 V), but switches to low-impedance conduction when transient voltage exceeds VBR, diverting surge current away from downstream ICs. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive surge stress.
The SMBJ6.0AHM3_B/H is rated for 100 A non-repetitive forward surge (8.3 ms half-sine), has a thermal resistance of 100 °C/W (junction-to-ambient), and supports operation from –55 °C to +150 °C junction temperature - enabling use in harsh environments including engine control units and industrial motor drives.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - maximum continuous reverse operating voltage before clamping begins; sets safe margin below system supply rails. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - verified breakdown threshold ensuring predictable turn-on during overvoltage events. |
| VC @ IPPM | ≤10.3 V at 58.3 A - clamping voltage limits stress on protected ICs during 600 W transient surges. |
| PPPM | 600 W (10/1000 µs waveform) - peak surge energy handling capacity for lightning and inductive switching transients. |
| IFSM | 100 A (8.3 ms half-sine) - surge current rating for short-duration fault conditions without bond wire failure. |
| TJ max. | +150 °C - enables deployment in under-hood automotive and high-temperature industrial enclosures. |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 0.205" × 0.130" footprint and matte tin-plated leads. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional polarity with cathode band marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); terminals are matte tin-plated, solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes conduction path during reverse-biased clamping. |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., 5 V rail or sensor output); absorbs positive-going surges toward ground. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Handles IEC 61000-4-5 Level 4 surges (4 kV line-earth) without degradation when mounted per recommended pad layout. |
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing. |
| MSL Level 1 (260 °C peak reflow) | Compatible with standard lead-free SMT reflow profiles without preconditioning or baking requirements. |
| Glass passivated junction | Ensures stable VBR tolerance and low leakage (<1 µA at 6.0 V) across lifetime and temperature extremes. |
| Halogen-free & RoHS-compliant | Meets environmental compliance mandates for industrial and automotive OEM supply chains (per Vishay Doc. 99912). |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|

IC Role / Device Role / Timing Role: Low-capacitance TVS shunting transient energy from sensor output to ground before reaching ADC input. Use Value: Clamps 600 W inductive spikes while maintaining signal integrity due to fast <1 ps response time and minimal leakage. |
| Consumer USB Port ESD Protection | Telecom DC Power Input Protection |
|
Use Scenario: Secondary-level ESD protection on VBUS line of USB 2.0 ports in set-top boxes and smart displays. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbing ±15 kV contact discharge per IEC 61000-4-2, placed after primary polymer fuse. Use Value: Maintains 6.0 V operating margin below 5 V nominal VBUS while clamping sub-100 ns ESD events to safe levels. |

IC Role / Device Role / Timing Role: Unidirectional TVS configured anode-to-rail to clamp negative-going surges on return path. Use Value: Withstands repeated 600 W transients per ITU-T K.20/21 standards while exhibiting <0.059 %/°C VBR drift. |
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 | Commercial-grade (non-AEC-Q101), same electrical specs, E3 suffix indicates RoHS-compliant commercial version. | Lacks automotive qualification; suitable for consumer or industrial non-automotive designs. | Select when AEC-Q101 is not required and cost optimization is prioritized. |
| SMBJ6.0CAHM3_B/H | Bidirectional variant (CA suffix), identical VWM = 6.0 V, but symmetric clamping for AC-coupled or floating lines. | Used where both polarities of transients must be suppressed (e.g., RS-485 differential pairs). | Choose only if bidirectional protection is needed; not a drop-in replacement due to polarity difference. |
Compared with SMBJ6.0AHM3_B/H, the E3/52 offers identical clamping performance at lower qualification cost, while the CAHM3_B/H provides dual-polarity protection at the expense of unidirectional optimization - requiring schematic and layout review before substitution.

FAQ
What is the clamping voltage of SMBJ6.0AHM3_B/H at its rated peak pulse current?
The SMBJ6.0AHM3_B/H clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 58.3 A (10/1000 µs waveform). This value is measured under standardized test conditions with 0.2" × 0.2" copper pads and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ6.0AHM3_B/H maintains this clamping performance across its full operating temperature range.
Is SMBJ6.0AHM3_B/H qualified for automotive applications?
Yes, SMBJ6.0AHM3_B/H is AEC-Q101 qualified, as indicated by the "HM3" suffix (halogen-free, RoHS-compliant, and AEC-Q101 qualified). It has undergone stress testing including temperature cycling, high-temperature operating life, and mechanical shock per AEC-Q101 requirements. The SMBJ6.0AHM3_B/H is approved for use in automotive powertrain, body electronics, and infotainment systems where transient immunity is critical.
What does the "B/H" in SMBJ6.0AHM3_B/H signify?
The "B/H" suffix in SMBJ6.0AHM3_B/H denotes the packaging configuration: "B" indicates tape-and-reel packaging per EIA-481 standard, and "H" specifies a 7-inch diameter reel containing 750 units. This format ensures compatibility with high-speed pick-and-place equipment and supports automated SMT assembly. The SMBJ6.0AHM3_B/H is supplied in moisture-barrier packaging meeting MSL Level 1 requirements.
How does SMBJ6.0AHM3_B/H differ from SMBJ6.0A-E3/52?
SMBJ6.0AHM3_B/H and SMBJ6.0A-E3/52 share identical electrical specifications (VWM, VBR, VC, PPPM) and SMB package, but differ in qualification and environmental compliance: HM3 denotes halogen-free + AEC-Q101, while E3/52 is RoHS-compliant commercial grade only. The SMBJ6.0AHM3_B/H is intended for automotive and high-reliability industrial use, whereas the E3/52 suits cost-sensitive consumer applications.
Can SMBJ6.0AHM3_B/H be used for bidirectional transient protection?
No, SMBJ6.0AHM3_B/H is a unidirectional TVS diode, marked with a cathode band and intended for clamping positive-going transients from anode to cathode. For bidirectional protection, the SMBJ6.0CAHM3_B/H variant must be used - it has symmetrical breakdown in both directions and no polarity marking. Using SMBJ6.0AHM3_B/H on AC or floating lines risks failure during reverse-polarity surges.
