Product details
Overview
SMBJ10CAHM3_A/H 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 a 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage at 35.3 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the SMBJ10CAHM3_A/H datasheet, SMBJ10CAHM3_A/H pinout, SMBJ10CAHM3_A/H application, or SMBJ10CAHM3_A/H equivalent, this device is selected for robust ESD and surge protection where bidirectional clamping, low clamping ratio (VC/VWM = 1.7), and AEC-Q101-qualified halogen-free construction are required.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional junction structure, enabling suppression of positive and negative transients without polarity sensitivity. Its glass-passivated silicon junction delivers sub-nanosecond response time and low incremental surge resistance (ΔV/ΔI ≈ 0.2 Ω), critical for protecting fast-switching circuits.
The device is rated for 150 °C maximum junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its thermal resistance (RθJA = 100 °C/W) and 5.0 W steady-state power dissipation support operation under sustained leakage conditions in ambient temperatures up to +85 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 10 V - Maximum continuous reverse voltage before significant leakage; sets operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 11.1–12.3 V at 1.0 mA - Guaranteed conduction onset range; ensures reliable triggering during overvoltage events. |
| VC (Clamping Voltage) | 17.0 V at IPPM = 35.3 A - Peak voltage seen by protected circuit during 600 W transient; defines worst-case stress level. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 µs) - Energy-handling capacity for standard lightning/surge waveforms; validates IEC 61000-4-5 compliance readiness. |
| ID (Max Reverse Leakage) | 5.0 µA at VWM - Low standby current minimizes power loss and avoids false triggering in high-impedance interfaces. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 5.59 mm max length and 2.20 mm max height; compatible with automated pick-and-place. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing; supports industrial and automotive designs. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Cathode/anode terminals are symmetrical; device functions identically regardless of orientation in PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative half-cycle) | Accepts reverse surge current during negative transients; forms one side of symmetrical clamping path. |
| Cathode | Transient current entry (positive half-cycle) | Accepts forward surge current during positive transients; completes bidirectional clamping loop with anode. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity constraints. |
| 600 W peak pulse power | Handles IEC 61000-4-5 Level 4 surges (4 kV line-to-line) when mounted on recommended 5.0 mm × 5.0 mm copper pads. |
| Halogen-free & RoHS-compliant (HM3 suffix) | Fulfills environmental compliance requirements for industrial and automotive end products without compromising surge performance. |
| Low clamping ratio (VC/VWM = 1.7) | Minimizes voltage overshoot across protected ICs - critical for 3.3 V and 5 V logic interfaces. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking; reduces manufacturing overhead in high-volume SMT lines. |
Applications
| Industrial Motor Drives | Automotive Sensor Interfaces |

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_A/H | RoHS-compliant but not halogen-free; same electrical specs and AEC-Q101 qualification. | Preferred for commercial-grade industrial systems where halogen content is unrestricted. | Select SMBJ10CAHE3_A/H when cost optimization is prioritized and halogen-free material is not mandated by end-product certification. |
| SMAJ10CAHM3 | Lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 140 °C/W). | Suitable only for lower-energy transients or space-constrained consumer PCBs with limited thermal mass. | Choose SMAJ10CAHM3 only if board area is critical and surge threat level is limited to IEC 61000-4-2 ESD, not full lightning surges. |
Compared with SMBJ10CAHE3_A/H, the SMBJ10CAHM3_A/H offers identical clamping performance with halogen-free compliance for stricter environmental programs; versus SMAJ10CAHM3, it delivers 50 % higher surge energy handling and superior thermal dissipation in the same design footprint.

FAQ
What is the clamping voltage of SMBJ10CAHM3_A/H at its rated peak pulse current?
The SMBJ10CAHM3_A/H has a maximum clamping voltage (VC) of 17.0 V at its rated peak pulse current (IPPM) of 35.3 A, measured using the standardized 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is confirmed in the Vishay datasheet Document Number 88392, page 2.
Is SMBJ10CAHM3_A/H suitable for automotive applications?
Yes, SMBJ10CAHM3_A/H is AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials (HM3 suffix), making it suitable for automotive sensor interfaces, body control modules, and infotainment power rails. Its 150 °C junction rating and validated reliability testing meet automotive environmental stress requirements.
How does the bidirectional configuration of SMBJ10CAHM3_A/H affect PCB layout?
The SMBJ10CAHM3_A/H has no polarity marking and functions identically in either orientation, simplifying PCB layout by eliminating cathode/anode routing constraints. Engineers can place it across differential pairs, AC-coupled lines, or floating references without directional verification - reducing design review cycles and assembly errors.
What is the thermal resistance of SMBJ10CAHM3_A/H, and how does it impact derating?
SMBJ10CAHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads. At 85 °C ambient, its peak pulse power must be derated to ~420 W per Figure 2 in the datasheet - a critical consideration for repetitive surge scenarios in enclosed enclosures.
Does SMBJ10CAHM3_A/H meet moisture sensitivity level (MSL) requirements for lead-free reflow?
Yes, SMBJ10CAHM3_A/H meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. This allows unlimited floor life and direct placement into standard lead-free reflow profiles without pre-baking - supporting high-yield, high-throughput SMT manufacturing for SMBJ10CAHM3_A/H.
