Product details
Overview
SMBJ10CAHM3/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 or power lines. It features 10 V standoff voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), and clamps to ≤17.0 V at 35.3 A peak surge current - used to protect MOSFETs, ICs, and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the SMBJ10CAHM3/I datasheet, SMBJ10CAHM3/I pinout, SMBJ10CAHM3/I application, or SMBJ10CAHM3/I equivalent, key selection criteria include bidirectional clamping capability, 17.0 V max clamping voltage at rated IPPM, AEC-Q101 qualification status, halogen-free RoHS compliance (HM3 suffix), and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche breakdown in both polarities, enabling transient suppression on AC-coupled or floating signal paths. Its glass-passivated junction ensures stable leakage (<5.0 μA at VWM) and fast response time (<1.0 ps), while low incremental surge resistance supports effective energy diversion during ESD or lightning-induced surges.
The SMBJ10CAHM3/I is rated for -55 °C to +150 °C operating junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its thermal resistance (RθJA = 100 °C/W) and RθJL = 20 °C/W define power derating behavior above 25 °C ambient, critical for sustained surge duty cycles up to 0.01%.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 10 V - maximum continuous reverse voltage before significant conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 11.1–12.3 V at 1 mA - guaranteed avalanche initiation range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | ≤17.0 V at IPPM = 35.3 A - peak voltage seen by protected circuit during 600 W transient; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 μs waveform) - standardized surge energy handling capacity; validates suitability for IEC 61000-4-5 Level 3/4 tests. |
| ID (Reverse Leakage) | ≤5.0 μA at VWM - minimal standby current; avoids signal distortion or battery drain in low-power sensor interfaces. |
| TJ max. | +150 °C - maximum junction temperature; enables use in under-hood automotive or high-ambient industrial environments. |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with standard SMT pick-and-place and reflow profiles. |
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 JESD 22-B102. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; symmetrical with cathode in bidirectional operation | Enables clamping during positive- or negative-going transients without external polarity consideration. |
| Cathode | Current exit point in forward bias; electrically identical to anode in bidirectional mode | Eliminates need for orientation verification during PCB assembly; simplifies layout for differential or AC-coupled lines. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Equal VBR and VC performance in both polarities - protects AC signal paths, RS-485 buses, and transformer-coupled interfaces without polarity constraints. |
| 600 W peak pulse power | Validated for 10/1000 μs waveform with 0.01% duty cycle - meets IEC 61000-4-5 surge immunity requirements for industrial control systems. |
| AEC-Q101 qualified (HM3 suffix) | Qualified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for infotainment, body electronics, and ADAS sensor protection. |
| Halogen-free & RoHS-compliant | Meets JEDEC J-STD-020 MSL Level 1 and JESD 201 Class 2 whisker resistance - supports green manufacturing and high-reliability reflow processes. |
| Low clamping ratio (VC/VBR ≈ 1.52) | 17.0 V clamping / 11.1 V min VBR - tight voltage margin reduces stress on protected ICs compared to higher-ratio TVS devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CAHE3/I | Same electrical specs, but RoHS-compliant commercial grade (not halogen-free); no AEC-Q101 qualification | Limited to non-automotive industrial or consumer use where halogen-free or automotive qualification is not required | Select when cost sensitivity outweighs halogen-free or automotive reliability requirements. |
| SMAJ10CAHM3 | Lower 400 W PPPM rating; SMA (DO-214AC) package with smaller 4.5 mm × 2.7 mm footprint | Acceptable for lower-energy transients (e.g., IEC 61000-4-2 ESD only); less robust for IEC 61000-4-5 surge | Choose for space-constrained designs where 400 W surge margin suffices and PCB area is premium. |
Compared with SMBJ10CAHE3/I, the SMBJ10CAHM3/I adds halogen-free construction and AEC-Q101 qualification without sacrificing clamping performance; versus SMAJ10CAHM3, it delivers 50% higher surge power handling in a slightly larger but thermally superior SMB package.

FAQ
What does the "HM3" suffix indicate in SMBJ10CAHM3/I?
The HM3 suffix denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It confirms that SMBJ10CAHM3/I meets automotive reliability standards including temperature cycling, highly accelerated life testing, and electrostatic discharge immunity - essential for use in vehicle subsystems beyond the cabin.
Is SMBJ10CAHM3/I suitable for protecting RS-485 communication lines?
Yes, SMBJ10CAHM3/I is well-suited for RS-485 line protection due to its bidirectional clamping, 17.0 V clamping voltage, and low leakage (<5.0 μA). Its symmetric response handles differential transients without polarity concerns, and the 600 W rating supports compliance with IEC 61000-4-5 surge testing commonly specified for industrial serial interfaces.
How does SMBJ10CAHM3/I differ from unidirectional SMBJ10A variants?
SMBJ10CAHM3/I provides symmetrical clamping in both directions with no cathode band marking, whereas unidirectional SMBJ10A has a marked cathode and conducts only in reverse bias. This makes SMBJ10CAHM3/I ideal for AC-coupled, floating, or bidirectional signal paths where polarity cannot be guaranteed - unlike SMBJ10A, which would fail to protect positive transients.
What is the maximum recommended PCB pad size for SMBJ10CAHM3/I to achieve rated 600 W performance?
To achieve full 600 W peak pulse power rating, SMBJ10CAHM3/I must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet. Smaller pads reduce thermal dissipation and cause premature failure under repeated surge conditions - always verify pad layout against Document Number 88392, Figure "Mounting Pad Layout".
Can SMBJ10CAHM3/I replace SMBJ12CA in a 12 V system?
No - SMBJ10CAHM3/I has a 10 V standoff voltage (VWM) and 11.1–12.3 V breakdown range, making it appropriate for nominal 10 V systems. Using it in a 12 V system risks premature conduction and increased leakage; SMBJ12CA (VWM = 12 V, VBR = 13.3–14.7 V) is the correct match for stable operation at 12 V nominal rails.
