Product details
Overview
SMCJ10CAHM3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 10 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), clamping voltage of 17.0 V at 88.2 A IPPM, and operates across -55 °C to +150 °C junction temperature range.
For engineers reviewing the SMCJ10CAHM3_A/I datasheet, SMCJ10CAHM3_A/I pinout, SMCJ10CAHM3_A/I application, or SMCJ10CAHM3_A/I equivalent, key selection criteria include bidirectional surge protection capability, AEC-Q101 qualification for automotive use, halogen-free RoHS compliance, and compatibility with automated SMT placement on PCBs requiring robust ESD/EMI transient immunity.
Technical Context
The SMCJ10CAHM3_A/I implements a glass-passivated silicon avalanche junction optimized for fast response (<1 ns) to transient overvoltages while maintaining low incremental surge resistance. Its bidirectional architecture enables symmetrical clamping in both polarities without polarity marking, making it suitable for AC-coupled signal lines and differential bus protection.
Thermally, it exhibits RθJA = 75 °C/W and RθJL = 15 °C/W, supporting reliable operation under repetitive surge conditions when mounted on 8.0 mm × 8.0 mm copper pads per terminal. The device meets MSL Level 1 per J-STD-020 and is qualified to AEC-Q101 for automotive under-hood and infotainment applications.
Key Specifications

| Package | SMC (DO-214AB) - Surface-mount package with 8.13 mm × 6.22 mm footprint and 3.20 mm height; compatible with standard SMT reflow profiles. |
Pinout & Package
SMCJ10CAHM3_A/I uses the SMC (DO-214AB) package - a two-terminal surface-mount device with no polarity marking for bidirectional operation. Terminals are matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point (bidirectional) | Accepts surge current in either polarity; connects to protected line or node requiring symmetric clamping. |
| Cathode | Transient current exit point (bidirectional) | Completes low-impedance path to ground or reference rail during overvoltage event; no band marking required. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485, CAN), and ungrounded circuits without polarity constraints. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock - suitable for engine control, ADAS, and infotainment modules. |
| Halogen-free & RoHS-compliant | Meets environmental compliance requirements for global electronics manufacturing (Vishay HM3 suffix), including lead-free reflow compatibility. |
| Low clamping ratio (VC/VBR ≈ 1.53) | Minimizes voltage overshoot during surge events, reducing risk of latch-up or gate oxide damage in protected MOSFETs and ICs. |
| MSL Level 1 moisture sensitivity | Allows indefinite floor life before reflow; eliminates baking requirement and simplifies SMT line logistics for high-volume production. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CAHE3_A/I | Lower PPPM (400 W), smaller SMA package (DO-214AC), higher RθJA (110 °C/W). | Suitable for space-constrained consumer ports but insufficient for automotive load dump. | Select when board area is critical and surge energy is limited to IEC 61000-4-2 only. |
| SMCJ10CAHE3_A/I | Same electrical specs and SMC package, but RoHS-compliant without halogen-free certification (E3 vs HM3). | Approved for commercial/industrial use; not certified for automotive due to missing AEC-Q101. | Choose for cost-sensitive non-automotive designs where halogen-free is not mandated. |
Compared with SMCJ10CAHE3_A/I, the SMCJ10CAHM3_A/I adds halogen-free compliance and AEC-Q101 qualification - essential for Tier 1 automotive supply chains - while matching all electrical and thermal performance.

FAQ
What is the clamping voltage of SMCJ10CAHM3_A/I at its rated peak pulse current?
The SMCJ10CAHM3_A/I has a maximum clamping voltage (VC) of 17.0 V when subjected to its rated peak pulse current (IPPM) of 88.2 A under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components experience controlled overvoltage stress during surge events. The SMCJ10CAHM3_A/I maintains this clamping performance across its full operating temperature range.
Is SMCJ10CAHM3_A/I suitable for automotive applications?
Yes, the SMCJ10CAHM3_A/I is AEC-Q101 qualified and specifically designated for automotive use via the HM3 suffix, indicating halogen-free, RoHS-compliant construction and validated reliability for under-hood and cabin environments. Its 1500 W PPPM rating and -55 °C to +150 °C operating range make it appropriate for protecting ECUs, ADAS sensors, and infotainment systems against ISO 7637-2 transients. The SMCJ10CAHM3_A/I meets stringent automotive qualification requirements beyond commercial-grade alternatives.
How does the bidirectional design of SMCJ10CAHM3_A/I affect its circuit implementation?
The bidirectional design of SMCJ10CAHM3_A/I eliminates polarity marking and allows direct placement across AC-coupled lines, differential pairs (e.g., CAN H/L, RS-485 A/B), or ungrounded signal paths without orientation concerns. Unlike unidirectional TVS diodes, the SMCJ10CAHM3_A/I provides symmetrical clamping in both directions, enabling simplified layout and reduced BOM count for balanced interfaces. Its terminals function interchangeably as anode/cathode depending on transient polarity, and no cathode band is present on the SMC package.
What is the thermal resistance profile of SMCJ10CAHM3_A/I, and how does it impact PCB layout?
The SMCJ10CAHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 15 °C/W when mounted on the recommended 8.0 mm × 8.0 mm copper pads per terminal. To maintain safe junction temperatures during repetitive surges, PCB layout must replicate this pad area and ensure adequate copper pour connectivity to ground or thermal planes. Reducing pad size increases RθJA and risks thermal runaway under sustained transient loads - a critical consideration for the SMCJ10CAHM3_A/I in high-duty-cycle applications.
Does SMCJ10CAHM3_A/I require special handling or packaging considerations?
No special handling is required beyond standard ESD-safe practices. The SMCJ10CAHM3_A/I is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and does not require dry pack or baking prior to reflow. It ships in 13" plastic tape-and-reel (I-packaging code) with 3500 units per reel, optimized for high-speed pick-and-place machines. The matte tin-plated leads comply with J-STD-002 and JESD 22-B102, ensuring robust solderability in lead-free reflow profiles - consistent with the SMCJ10CAHM3_A/I's halogen-free construction.
