Product details
Overview
SMCJ6.0CAHE3/9AT 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 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (PPPM), and clamps transients to ≤10.3 V at 145.6 A (10/1000 µs waveform), making it suitable for automotive sensor line protection.
For engineers reviewing the SMCJ6.0CAHE3/9AT datasheet, SMCJ6.0CAHE3/9AT pinout, SMCJ6.0CAHE3/9AT application, or SMCJ6.0CAHE3/9AT equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 1500 W surge rating, low clamping voltage under high IPPM, and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamped crowbar during ESD or lightning-induced transients, leveraging an avalanche junction to conduct excess energy to ground when reverse voltage exceeds VBR. Its bidirectional symmetry ensures identical clamping behavior in both polarities-critical for AC-coupled or floating signal lines.
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15 °C/W, enabling reliable operation up to TJ = +150 °C. The matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards, and the device is rated MSL Level 1 (260 °C peak reflow).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 6.67 V / 7.37 V at 10 mA - Ensures tight breakdown tolerance for predictable turn-on |
| VC @ IPPM | ≤10.3 V at 145.6 A - Low clamping voltage preserves downstream IC integrity during surge events |
| PPPM | 1500 W - Handles high-energy transients per 10/1000 µs waveform without failure |
| ID @ VWM | ≤1000 µA - Minimal leakage preserves signal integrity in low-power circuits |
| TJ max. | +150 °C - Supports under-hood automotive environments and industrial enclosures |
| Package | SMC (DO-214AB) - Standardized surface-mount outline compatible with automated placement and reflow |
Pinout & Package
SMCJ6.0CAHE3/9AT uses the SMC (DO-214AB) package: a 2-terminal, non-polarized, bidirectional TVS diode with no cathode marking. Terminals are matte tin-plated leads suitable for J-STD-002-compliant soldering. Mounting requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal for full 1500 W rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current return path (bidirectional) | Functions identically to cathode under reverse bias; symmetric conduction enables AC line protection |
| Cathode | Transient current return path (bidirectional) | No polarity marking; both terminals serve as interchangeable surge current paths |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per AEC specification |
| Glass passivated junction | Enhances long-term stability and moisture resistance versus epoxy-passivated alternatives |
| MSL Level 1 | Allows unlimited floor life and single-reflow processing at 260 °C peak without baking |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a/5a) |
| UL 94 V-0 molding compound | Meets flammability safety requirements for enclosed industrial and automotive modules |
Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC5.0CA | Lower PPPM (500 W), higher VBR (6.4–7.25 V), same SMC package | Not AEC-Q101 qualified; suited for cost-sensitive consumer designs only | Select when 500 W surge rating suffices and automotive qualification is unnecessary |
| SMCJ6.0AHE3/9AT | Unidirectional version; identical VWM/VBR/PPPM but asymmetric conduction | Requires polarity-aware layout; unsuitable for AC or floating signals | Choose only for DC-biased rails where reverse conduction must be blocked |
Compared with SAC5.0CA and SMCJ6.0AHE3/9AT, the SMCJ6.0CAHE3/9AT uniquely combines AEC-Q101 qualification, 1500 W bidirectional clamping, and industry-standard SMC footprint-making it the preferred choice for automotive and industrial signal-line protection where polarity independence and high-reliability validation are mandatory.

FAQ
What does the "CA" suffix indicate in SMCJ6.0CAHE3/9AT?
The "CA" suffix denotes a bidirectional configuration: SMCJ6.0CAHE3/9AT conducts and clamps transients equally in both directions, unlike unidirectional variants (e.g., SMCJ6.0AHE3/9AT). This eliminates polarity concerns during PCB layout and supports AC-coupled or floating signal lines-critical for CAN, RS-485, and sensor differential pairs.
Is SMCJ6.0CAHE3/9AT qualified for automotive use?
Yes, SMCJ6.0CAHE3/9AT is AEC-Q101 qualified, as confirmed by Vishay's ordering code "HE3" suffix and documentation (Doc. #88394, Rev. 09-Jan-2024). It undergoes stress testing for temperature cycling, high-temperature reverse bias, and ESD-meeting requirements for under-hood and chassis-mounted automotive electronics.
What is the maximum clamping voltage for SMCJ6.0CAHE3/9AT under surge conditions?
The maximum clamping voltage (VC) for SMCJ6.0CAHE3/9AT is 10.3 V at 145.6 A peak pulse current (IPPM), tested with a 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and ensures downstream ICs like CAN transceivers or microcontrollers remain within absolute maximum ratings during surge events.
How does the SMC (DO-214AB) package of SMCJ6.0CAHE3/9AT affect thermal performance?
The SMC (DO-214AB) package delivers RθJA = 75 °C/W and RθJL = 15 °C/W, enabling efficient heat dissipation when mounted on 0.31" × 0.31" copper pads. This allows SMCJ6.0CAHE3/9AT to sustain its 1500 W PPPM rating without derating below TA = 25 °C, supporting compact, high-density board layouts in space-constrained modules.
Can SMCJ6.0CAHE3/9AT replace older SMCJ6.0CA parts without layout changes?
Yes, SMCJ6.0CAHE3/9AT maintains identical SMC (DO-214AB) mechanical dimensions, pinout, and electrical specifications as legacy SMCJ6.0CA variants. The "HE3" suffix adds AEC-Q101 qualification and RoHS compliance but retains full drop-in compatibility-no PCB redesign or footprint modification is required for migration.
