Product details
Overview
SMCJ10CAHM3/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 10 V standoff voltage (VWM), 17.0 V maximum clamping voltage (VC) at 88.2 A peak pulse current (IPPM), and 1500 W peak pulse power (10/1000 µs waveform), commonly deployed on automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the SMCJ10CAHM3/H datasheet, SMCJ10CAHM3/H pinout, SMCJ10CAHM3/H application, or SMCJ10CAHM3/H equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification status, halogen-free RoHS compliance (HM3 suffix), thermal resistance (RθJA = 75 °C/W), and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This device operates as a voltage-clamping protector using an avalanche breakdown mechanism, with symmetrical reverse/forward conduction behavior due to its bidirectional construction. Its low incremental surge resistance and fast response time (<1 ns) enable effective suppression of ESD, lightning-induced transients, and inductive switching spikes.
The SMCJ10CAHM3/H is rated for -55 °C to +150 °C junction temperature, meets MSL Level 1 per J-STD-020 (260 °C peak reflow), and is qualified to AEC-Q101 for automotive use - confirmed by the HM3 suffix denoting halogen-free, RoHS-compliant, and AEC-Q101-qualified construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 11.1 V / 12.3 V - Breakdown voltage range at 1.0 mA test current, defining turn-on threshold |
| VC @ IPPM | 17.0 V - Clamped voltage during 10/1000 µs surge at 88.2 A, limiting stress on downstream ICs |
| PPPM | 1500 W - Peak pulse power handling capability under standardized transient waveform |
| TJ max | +150 °C - Maximum junction temperature enabling operation in under-hood automotive environments |

| Package | SMC (DO-214AB) - Surface-mount package with 8.0 mm × 8.0 mm thermal pad layout per datasheet fig. 2 |
Pinout & Package
SMCJ10CAHM3/H uses the SMC (DO-214AB) surface-mount package with two terminals and no polarity marking (bidirectional configuration). The case conforms to UL 94 V-0 flammability rating and features matte tin-plated leads solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (either direction) | One terminal of symmetrical avalanche junction; accepts surge current regardless of polarity |
| Cathode | Transient current exit (either direction) | Second terminal of symmetrical avalanche junction; completes clamping path during bidirectional events |
Key Features

|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces |
| Halogen-free & RoHS-compliant (HM3) | Meets global environmental regulations and JEDEC JESD201 Class 2 whisker resistance |
| Low incremental surge resistance | Enables tighter clamping (VC = 17.0 V) and lower let-through energy during 1500 W transients |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard 260 °C reflow without baking preconditioning |
| Glass passivated junction | Ensures stable breakdown characteristics and long-term reliability under repeated surge stress |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping TVS placed directly at connector or IC input pins to shunt transients before reaching protected circuitry. Use Value: Maintains signal integrity under ISO 7637-2 Pulse 5a (load dump) and IEC 61000-4-2 ±15 kV contact discharge due to symmetrical 11.1–12.3 V VBR and 17.0 V VC. | Use Scenario: Safeguarding PLC digital input modules and fieldbus interfaces (RS-485, Profibus) against induced surges from nearby motor switching. IC Role / Device Role / Timing Role: Primary overvoltage clamp on signal lines between field wiring and isolation barrier or receiver IC. Use Value: Withstands 1500 W pulses without degradation, ensuring system uptime in factory automation where maintenance windows are constrained. |
| Consumer Power Adapter Input | Telecom Line Card Protection |
Use Scenario: Secondary-side transient suppression on 12 V DC output rails of wall adapters and USB-C PD chargers exposed to user-handling ESD. IC Role / Device Role / Timing Role: Fast-response clamp parallel to load, activated within nanoseconds to limit voltage overshoot during plug insertion or cable flex events. Use Value: Halogen-free HM3 construction supports eco-label compliance (e.g., Energy Star, EPEAT), while 10 V VWM avoids false triggering during normal 12 V rail ripple. | Use Scenario: Front-end protection of Ethernet PHYs and DSL line drivers in network edge equipment subjected to lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Bidirectional TVS placed across differential pairs or between line and ground to absorb asymmetric transients. Use Value: Symmetrical clamping ensures equal protection on both polarities of telecom signals, critical for maintaining bit error rate (BER) in high-speed data links. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Lower PPPM (400 W), smaller SMA package, higher RθJA (110 °C/W) | Suitable only for lower-energy transients; not AEC-Q101 qualified | Select when cost or board space is prioritized over automotive-grade surge margin |
| 1.5KE10CA | Through-hole DO-201 package, same 10 V VWM, but slower response and no MSL Level 1 rating | Used in legacy industrial power supplies where SMT is not required | Choose for prototyping or repair scenarios requiring through-hole compatibility |
Compared with SMAJ10CA and 1.5KE10CA, the SMCJ10CAHM3/H delivers superior surge robustness (1500 W vs. 400 W or ~1500 W with inferior thermal performance), AEC-Q101 validation, and optimized SMT manufacturability - making it the preferred choice for production automotive and high-reliability industrial designs.

FAQ
What does the 'HM3' suffix indicate in SMCJ10CAHM3/H?
The 'HM3' suffix in SMCJ10CAHM3/H denotes halogen-free, RoHS-compliant construction qualified to AEC-Q101 for automotive use. It confirms compliance with JEDEC JESD201 Class 2 whisker resistance, UL 94 V-0 flammability rating, and suitability for lead-free reflow up to 260 °C without preconditioning - all verified in Vishay document 88394.
Is SMCJ10CAHM3/H unidirectional or bidirectional?
SMCJ10CAHM3/H is a bidirectional transient voltage suppressor, as indicated by the 'CA' suffix. Its electrical characteristics - including symmetrical breakdown (11.1–12.3 V), clamping (17.0 V), and leakage - apply identically in both directions, enabling protection of AC-coupled or differential signal lines without polarity concerns.
What is the maximum clamping voltage of SMCJ10CAHM3/H and at what current?
The maximum clamping voltage (VC) of SMCJ10CAHM3/H is 17.0 V, measured at 88.2 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is specified in the Electrical Characteristics table of Vishay document 88394 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Can SMCJ10CAHM3/H be used in place of SMCJ10A?
No - SMCJ10CAHM3/H is bidirectional, while SMCJ10A is unidirectional. They differ in polarity marking (no band on SMCJ10CAHM3/H vs. cathode band on SMCJ10A), forward voltage behavior (VF = 3.5 V at 100 A applies only to unidirectional types), and application scope. Substitution requires circuit review to ensure bidirectional clamping meets system requirements.
What PCB pad layout is recommended for optimal thermal performance of SMCJ10CAHM3/H?
Vishay specifies a minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad area per terminal for SMCJ10CAHM3/H to achieve rated power dissipation and thermal resistance (RθJA = 75 °C/W). This layout is defined in Figure 2 of document 88394 and must be implemented to sustain 1500 W peak pulse power without junction overheating.
