Product details
Overview
SMBJ6.0CAHM3_B/I from Vishay General Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features 6.4 V minimum breakdown voltage (VBR), 6.0 V maximum stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 58.3 A peak pulse current (IPPM), and 10.3 V maximum clamping voltage (VC) - used to protect MOSFETs, ICs, and sensor interfaces in industrial and telecom systems.
For engineers reviewing the SMBJ6.0CAHM3_B/I datasheet, SMBJ6.0CAHM3_B/I pinout, SMBJ6.0CAHM3_B/I application, or SMBJ6.0CAHM3_B/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification status, halogen-free RoHS compliance, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical bidirectional avalanche breakdown behavior, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable VBR tolerance (±5% typical) and low incremental surge resistance under repetitive 10/1000 µs transients at 0.01% duty cycle.
The SMBJ6.0CAHM3_B/I exhibits fast response time (<1 ps), low leakage (<800 µA at VWM), and thermal resistance of 100 °C/W (junction-to-ambient) when mounted per recommended pad layout. It meets UL 497B recognition (QVGQ2) and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.4 V to 7.07 V - defines guaranteed avalanche conduction onset in both directions; ensures reliable triggering before downstream circuit damage. |
| VWM | 6.0 V - maximum continuous reverse voltage before significant leakage; sets safe operating margin below VBR. |
| IPPM | 58.3 A - peak surge current it can shunt during 10/1000 µs transient; determines survivability against IEC 61000-4-5 Level 4 surges. |
| VC (max) | 10.3 V - clamped voltage across device at IPPM; directly limits stress on protected ICs or MOSFETs. |
| PPPM | 600 W - peak pulse power handling capacity; enables robust protection against lightning-induced or inductive-switching transients. |
| TJ max. | +150 °C - maximum junction temperature; supports operation in high-ambient environments like automotive engine bays or industrial enclosures. |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with standard reflow profiles and pick-and-place equipment. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Terminals are matte tin-plated leads, solderable per J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient current path | Both terminals function identically due to bidirectional construction; no cathode band marking required. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485), or ungrounded power rails without polarity concerns. |
| 600 W peak pulse power | Withstands IEC 61000-4-5 combination wave surges up to 4 kV (open-circuit)/2 kA (short-circuit) when properly laid out. |
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for ADAS and body control modules. |
| Halogen-free & RoHS-compliant | Meets environmental compliance requirements for consumer, industrial, and automotive electronics without compromising surge performance. |
| MSL Level 1 (260 °C peak) | Allows unlimited floor life and compatibility with standard lead-free reflow profiles without baking preconditioning. |
Applications
| Industrial Motor Drives | Automotive Body Control Modules |

Use Scenario: Surge suppression on LIN bus lines and sensor supply rails in door modules and lighting controllers. IC Role / Device Role / Timing Role: Bidirectional transient suppressor absorbing load-dump and jump-start induced transients on 12 V systems. Use Value: Withstands repetitive 600 W pulses and operates reliably from −55 °C to +150 °C, meeting automotive ambient requirements. |
| Telecom Power Feeds | Consumer Sensor Interfaces |
|
Use Scenario: Input-stage protection for PoE-powered devices and DSL line interface circuits subjected to lightning-induced surges. IC Role / Device Role / Timing Role: First-line defense clamping common-mode transients before they reach isolation transformers or PHY ICs. Use Value: Low clamping voltage (10.3 V) preserves headroom for 12 V–24 V DC-DC converters while maintaining fast <1 ps response. |
Use Scenario: ESD and surge protection for I²C/SPI lines connecting MEMS sensors (e.g., accelerometers, humidity sensors) to host MCUs. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS minimizing signal distortion on high-speed digital sensor buses. Use Value: Junction capacitance <100 pF (typ.) at zero bias ensures minimal impact on rise/fall times of 100 kHz–400 kHz sensor communication. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0CAHE3_B/I | Same electrical specs, but RoHS-compliant commercial grade (non-halogen-free); lacks AEC-Q101 qualification. | Suitable for non-automotive industrial or consumer designs where halogen-free requirement is not mandated. | Select when cost sensitivity outweighs halogen-free or automotive qualification needs. |
| SMAJ6.0CAHM3 | Lower 400 W peak pulse power; SMA package (smaller footprint, higher thermal resistance). | Limited to lower-energy transients; less robust in high-surge industrial environments. | Choose only if board space is constrained and surge threat level is ≤IEC 61000-4-5 Level 2. |
Compared with SMBJ6.0CAHE3_B/I, the SMBJ6.0CAHM3_B/I adds halogen-free compliance and AEC-Q101 qualification without sacrificing clamping performance; versus SMAJ6.0CAHM3, it delivers 50% higher surge energy handling and superior thermal dissipation in the larger SMB package.

FAQ
What is the breakdown voltage range for SMBJ6.0CAHM3_B/I?
The SMBJ6.0CAHM3_B/I has a specified breakdown voltage (VBR) range of 6.4 V to 7.07 V at 10 mA test current, measured bidirectionally. This range ensures consistent avalanche initiation across manufacturing lots and temperature extremes, and is verified per ANSI/IEEE C62.35 standards. The SMBJ6.0CAHM3_B/I maintains this specification under TA = 25 °C conditions with derating above that temperature.
Is SMBJ6.0CAHM3_B/I suitable for automotive applications?
Yes, SMBJ6.0CAHM3_B/I is AEC-Q101 qualified (denoted by HM3 suffix) and rated for operation from −55 °C to +150 °C. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD verification. The SMBJ6.0CAHM3_B/I is explicitly approved for use in automotive body control modules, lighting systems, and sensor interfaces where transient immunity and long-term reliability are critical.
What does the "CA" suffix indicate in SMBJ6.0CAHM3_B/I?
The "CA" suffix in SMBJ6.0CAHM3_B/I designates a bidirectional configuration, meaning the device provides symmetrical transient suppression in both polarities - essential for protecting AC-coupled lines, differential buses (e.g., RS-485), or ungrounded power rails. Unlike unidirectional variants (e.g., SMBJ6.0AHM3_B/I), the SMBJ6.0CAHM3_B/I has no cathode marking and conducts identically in either direction above VBR.
How does SMBJ6.0CAHM3_B/I compare to SMAJ6.0CAHM3 in terms of surge handling?
SMBJ6.0CAHM3_B/I delivers 600 W peak pulse power (10/1000 µs), whereas SMAJ6.0CAHM3 is rated for 400 W - a 50% increase in energy absorption capacity. The SMBJ6.0CAHM3_B/I also features lower thermal resistance (RθJA = 100 °C/W vs. ~140 °C/W for SMAJ), enabling better heat dissipation during repetitive surges. This makes SMBJ6.0CAHM3_B/I preferable for high-threat environments like factory automation or outdoor telecom equipment.
What packaging and reel options are available for SMBJ6.0CAHM3_B/I?
SMBJ6.0CAHM3_B/I is supplied in 13-inch plastic tape-and-reel format (I-type carrier), with 3200 units per reel. The "I" in the suffix denotes this delivery mode, while "B" indicates the base P/N revision. The device uses standard SMB (DO-214AA) packaging with matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards - fully compatible with automated SMT assembly lines.
