Product details
Overview
SMB8J10CAHM3_A/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on signal and power lines. It features a 10 V stand-off voltage (VWM), 17.0 V maximum clamping voltage (VC) at 10 A peak pulse current (IPPM), and 800 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMB8J10CAHM3_A/I datasheet, SMB8J10CAHM3_A/I pinout, SMB8J10CAHM3_A/I application, or SMB8J10CAHM3_A/I equivalent, this device is selected for robust ESD and lightning surge immunity in AEC-Q101-compliant automotive subsystems, where low clamping voltage and halogen-free RoHS compliance are mandatory design requirements.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction delivers sub-nanosecond response time and low incremental surge resistance, critical for suppressing fast transients induced by inductive switching or ESD events.
Rated for -55 °C to +150 °C operating junction temperature and qualified to AEC-Q101, SMB8J10CAHM3_A/I supports automotive-grade reliability under thermal cycling and mechanical stress. The HM3 suffix confirms halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance and MSL Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 12 V automotive supply rails. |
| VBR min / max | 11.1 V / 12.3 V at 1 mA - Verified breakdown threshold ensures consistent turn-on behavior across production lots. |
| VC @ IPPM | 17.0 V at 10 A - Clamping voltage limits downstream IC stress during 800 W surge; enables compatibility with 24 V logic-level interfaces. |
| PPPM | 800 W (10/1000 µs) - Sustains high-energy transients common in load-dump and ISO 7637-2 Pulse 5a scenarios. |
| ID @ VWM | 1.0 µA - Ultra-low leakage preserves signal integrity in high-impedance sensor bias networks. |
| TJ max | +150 °C - Supports under-hood placement in engine control units and ADAS modules without derating. |
| Package | SMB (DO-214AA) - Standardized surface-mount footprint compatible with automated assembly and IPC-7351B land patterns. |
Pinout & Package
Two-terminal bidirectional device in SMB (DO-214AA) package; no polarity marking - symmetrical terminals function identically for AC or differential line protection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals conduct equally during positive or negative overvoltage events; no PCB layout polarity constraint required. |
| Cathode Band (absent) | Polarity indicator | Not applicable - bidirectional construction eliminates cathode band; device mounts without orientation check. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, humidity testing, and mechanical shock per JESD47. |
| Halogen-free & RoHS-compliant (HM3) | Meets EU Directive 2011/65/EU and JEDEC J-STD-609A Class 1 for environmentally constrained supply chains. |
| Low clamping ratio (VC/VBR ≈ 1.43) | Minimizes voltage overshoot during surge, reducing risk of latch-up or gate oxide damage in protected MOSFETs or MCUs. |
| MSL Level 1 (260 °C peak) | Enables standard reflow soldering without pre-baking; supports high-volume SMT manufacturing. |
| Glass-passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift in harsh environments. |
Applications
| Automotive Sensor Interface | Industrial CAN Bus Protection |
|---|---|
|
Use Scenario: Protecting LIN or SENT signal lines from load dump and ESD in body control modules. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt transients before reaching PHY or MCU input pins. Use Value: 17.0 V clamping ensures signal integrity remains within 5 V tolerant input range of automotive microcontrollers under ISO 10605 30 kV contact discharge. |
Use Scenario: Safeguarding CANH/CANL differential pair against ISO 7637-2 Pulse 1 and Pulse 2b surges in factory automation nodes. IC Role / Device Role / Timing Role: Symmetric TVS pair (one per line) absorbing common-mode and differential transients without disrupting 1 Mbps data timing. Use Value: Sub-1 ns response time prevents bit errors during transient events; 10 µA leakage avoids CAN bus bias current accumulation. |
| Consumer Power Adapter Input | Smart Meter Communication Port |
|
Use Scenario: Secondary-side DC input protection in USB-C PD adapters exposed to mains-borne surges. IC Role / Device Role / Timing Role: Standoff-rated clamp on 9–20 V output rail, coordinating with upstream MOV and fuse for staged overvoltage defense. Use Value: 800 W PPPM handles repetitive 10/1000 µs surges per IEC 61000-4-5 Level 3, extending adapter field life beyond 5 years. |
Use Scenario: RS-485 port protection in utility smart meters installed in outdoor distribution cabinets. IC Role / Device Role / Timing Role: First-line transient absorber on differential bus lines, placed before isolated transceiver to prevent latch-up during lightning-induced ground shifts. Use Value: +150 °C TJ rating maintains clamping performance during summer ambient temperatures exceeding 70 °C inside sealed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMB8J10CAHE3_A/I | Same electrical specs; RoHS-compliant but not halogen-free (E3 vs HM3). | Lacks halogen-free certification required for Tier 1 automotive sourcing programs. | Select SMB8J10CAHM3_A/I when compliance with VW 80101 or GMW3172 material restrictions is mandatory. |
| SMAJ10CA | Lower PPPM (400 W), larger SMA package (DO-214AC), higher RθJA (90 °C/W). | Insufficient energy handling for ISO 7637-2 Pulse 5a; unsuitable for under-hood thermal environments. | Choose SMB8J10CAHM3_A/I for 800 W surge capability and +150 °C operation where SMAJ10CA fails validation. |
Compared with SMB8J10CAHE3_A/I, SMB8J10CAHM3_A/I adds halogen-free assurance without sacrificing performance; versus SMAJ10CA, it delivers double the surge power rating and superior thermal resistance in identical board space.

FAQ
What is the clamping voltage of SMB8J10CAHM3_A/I at its rated peak pulse current?
The SMB8J10CAHM3_A/I has a maximum clamping voltage (VC) of 17.0 V when subjected to its specified 10 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured and guaranteed per Vishay Document Number 88422, ensuring predictable voltage limiting during surge events without exceeding protected circuit thresholds.
Is SMB8J10CAHM3_A/I suitable for automotive applications?
Yes, SMB8J10CAHM3_A/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction - meeting stringent automotive requirements for reliability, material content, and thermal endurance. It is explicitly rated for operation from -55 °C to +150 °C junction temperature, supporting under-hood and chassis-mounted deployments.
How does the bidirectional configuration of SMB8J10CAHM3_A/I affect PCB layout?
The SMB8J10CAHM3_A/I has no polarity marking and functions identically in either orientation, eliminating orientation checks during placement. This simplifies PCB layout for differential or AC-coupled lines - such as CAN, LIN, or RS-485 - and removes risk of misassembly that could occur with unidirectional TVS devices.
What is the meaning of the "HM3" suffix in SMB8J10CAHM3_A/I?
The "HM3" suffix in SMB8J10CAHM3_A/I denotes halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance and MSL Level 1 rating (260 °C peak reflow). It distinguishes this variant from E3 (RoHS only) and HE3 (AEC-Q101 + RoHS), confirming full compliance with automotive material restriction standards like VW 80101.
Can SMB8J10CAHM3_A/I replace SMBJ10CA in an existing design?
No - SMB8J10CAHM3_A/I is not a drop-in replacement for SMBJ10CA. While both are bidirectional 10 V TVS diodes in SMB packages, SMB8J10CAHM3_A/I is rated for 800 W PPPM and 10 A IPPM, whereas SMBJ10CA is rated for 600 W and 6.8 A. Substituting without validation risks inadequate surge handling and thermal overload under identical test conditions.
