Product details
Overview
SMCJ6.0CAHM3_A/H from Vishay General Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) in SMC (DO-214AB) package, designed for clamping voltage transients up to 1500 W peak pulse power with 10.3 V max clamping voltage at 145.6 A IPPM, 6.40–7.37 V breakdown range, and 6.0 V standoff voltage - deployed in automotive sensor signal lines and industrial I/O protection.
For engineers reviewing the SMCJ6.0CAHM3_A/H datasheet, SMCJ6.0CAHM3_A/H pinout, SMCJ6.0CAHM3_A/H application, or SMCJ6.0CAHM3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification status, 1500 W PPPM rating, SMC package thermal performance (RθJA = 75 °C/W), and halogen-free RoHS compliance per HM3 suffix.
Technical Context
This device operates as a bidirectional avalanche diode, leveraging glass-passivated junctions to achieve sub-nanosecond response time and low incremental surge resistance. Its symmetrical VBR min/max (6.40–7.37 V) and identical forward/reverse clamping behavior ensure consistent protection on AC-coupled or differential signal paths.
Designed for mounting on 8.0 mm × 8.0 mm copper pads, it delivers 1500 W peak pulse power under 10/1000 μs waveform while maintaining TJ ≤ 150 °C. The HM3 suffix confirms halogen-free, RoHS-compliant construction and AEC-Q101 qualification for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.40 V / 7.37 V - ensures reliable avalanche conduction onset across temperature and unit variation |
| VWM | 6.0 V - maximum continuous reverse operating voltage before leakage exceeds 10 μA |
| VC @ IPPM | 10.3 V - clamped voltage during 145.6 A 10/1000 μs surge, defining protected circuit's worst-case overvoltage |
| PPPM | 1500 W - peak transient energy absorption capacity under standardized surge waveform |
| TJ max. | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| RθJA | 75 °C/W - thermal resistance from junction to ambient on recommended 8 mm × 8 mm pad layout |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 2.06 mm height and 7.75 mm length |
Pinout & Package
SMCJ6.0CAHM3_A/H uses a two-terminal SMC (DO-214AB) package with no polarity marking for bidirectional operation. Terminals are matte tin-plated, 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 (reverse bias) | One side of symmetrical avalanche junction; conducts during negative transients |
| Cathode | Transient current entry (forward bias) | Other side of symmetrical junction; conducts during positive transients |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC, differential, or floating signal lines without polarity concerns |
| AEC-Q101 qualified | Validated for automotive applications including engine control modules and ADAS sensor interfaces |
| Halogen-free & RoHS | HM3 suffix certifies compliance with environmental standards and eliminates corrosive halogen emissions during reflow |
| Low RθJL (15 °C/W) | Supports efficient heat transfer to PCB copper, critical for sustained surge duty cycles |
| MSL Level 1 | Unlimited floor life at ≤30 °C/85 % RH, eliminating bake requirements prior to assembly |
Applications
| Automotive Sensor Protection | Industrial PLC I/O |
|---|---|
Use Scenario: Protecting CAN/FlexRay transceiver inputs and analog sensor outputs (e.g., pressure, temperature) from load dump and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at connector or IC input pins to clamp transients before they reach sensitive analog front-ends. Use Value: Maintains signal integrity by limiting overvoltage to ≤10.3 V during 145.6 A surges, preserving ADC accuracy and preventing latch-up in microcontrollers. | Use Scenario: Shielding digital and analog I/O channels of programmable logic controllers from inductive switching spikes in factory automation systems. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 24 V DC field wiring, installed upstream of optocouplers or level-shifters. Use Value: Absorbs 1500 W transient energy without degradation, ensuring long-term reliability in high-noise industrial environments with frequent relay coil de-energization. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Safeguarding Ethernet PHY interfaces and DSL line drivers against lightning-induced surges on outdoor-facing telecom equipment. IC Role / Device Role / Timing Role: First-stage protection element on unshielded twisted-pair (UTP) ports, coordinated with GDT or MOV secondary stages. Use Value: Sub-ns response time prevents voltage overshoot beyond 10.3 V, protecting 3.3 V or 5 V PHY transceivers rated for ≤12 V absolute maximum. | Use Scenario: Suppressing fast-rising line transients (e.g., switch-mode noise, capacitor discharge) at the AC-DC adapter primary-side rectifier output. IC Role / Device Role / Timing Role: Secondary-side transient suppressor across bulk capacitor terminals to prevent overvoltage stress on downstream regulators. Use Value: Withstands repeated 10/1000 μs surges up to 1500 W while maintaining 6.0 V standoff, avoiding false triggering during normal 12 V rail ripple. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0CAHE3_A/H | Lower PPPM (400 W), smaller SMA package, higher RθJA (110 °C/W) | Suitable only for low-energy transients; not recommended for automotive load-dump scenarios | Select when board space is constrained and surge energy remains below 400 W |
| SMCJ6.0CAHE3_A/H | Same SMC package and electrical specs, but commercial-grade (non-AEC-Q101) and RoHS-compliant without halogen-free certification | Lacks automotive qualification; acceptable for industrial or consumer use where AEC-Q101 is not mandated | Choose for cost-sensitive non-automotive designs requiring identical form-factor and clamping performance |
Compared with SMCJ6.0CAHM3_A/H, SMAJ6.0CAHE3_A/H trades surge robustness for footprint reduction, while SMCJ6.0CAHE3_A/H retains mechanical and electrical equivalence but omits halogen-free and AEC-Q101 validation - making the HM3 variant the sole choice for production automotive electronics requiring full compliance traceability.

FAQ
What does the "CA" suffix indicate in SMCJ6.0CAHM3_A/H?
The "CA" suffix denotes a bidirectional configuration, meaning SMCJ6.0CAHM3_A/H provides symmetrical clamping in both polarities - essential for protecting AC-coupled, differential, or floating signal paths without polarity constraints. Unlike unidirectional variants (e.g., SMCJ6.0AHM3_A/H), it has no cathode band marking and exhibits identical VBR and VC characteristics in forward and reverse directions.
Is SMCJ6.0CAHM3_A/H qualified for automotive applications?
Yes, SMCJ6.0CAHM3_A/H is AEC-Q101 qualified, as confirmed by the HM3 suffix and Vishay documentation. This qualification validates its reliability under automotive temperature cycling, humidity, mechanical shock, and lifetime surge stress conditions - making it suitable for engine control units, body electronics, and ADAS sensor modules where failure is not acceptable.
What is the maximum clamping voltage of SMCJ6.0CAHM3_A/H under surge conditions?
The maximum clamping voltage (VC) of SMCJ6.0CAHM3_A/H is 10.3 V at 145.6 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is measured with the device mounted on 8.0 mm × 8.0 mm copper pads per JEDEC guidelines.
How does the HM3 suffix differ from HE3 in SMCJ6.0CAHM3_A/H?
The HM3 suffix in SMCJ6.0CAHM3_A/H indicates halogen-free, RoHS-compliant, and AEC-Q101-qualified construction, whereas HE3 denotes RoHS-compliant and AEC-Q101-qualified but not halogen-free. Both share identical electrical specs and SMC packaging, but HM3 meets stricter environmental mandates required by certain Tier 1 automotive customers and EU regulatory frameworks.
Can SMCJ6.0CAHM3_A/H be used in place of a unidirectional TVS like SMCJ6.0AHM3_A/H?
SMCJ6.0CAHM3_A/H can replace unidirectional SMCJ6.0AHM3_A/H only in circuits where polarity is undefined or bidirectional protection is explicitly needed - such as across transformer windings or differential bus lines. In DC-biased applications with defined anode/cathode orientation, using the bidirectional version may reduce effective standoff margin and is not recommended without circuit-level verification of reverse leakage and clamping symmetry.
