Product details
Overview
SMCJ6.0CAHE3/57T 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 (10/1000 µs), and clamps transients to ≤10.3 V at 145.6 A peak surge current - ideal for automotive sensor signal line protection per AEC-Q101.
For engineers reviewing the SMCJ6.0CAHE3/57T datasheet, SMCJ6.0CAHE3/57T pinout, SMCJ6.0CAHE3/57T application, or SMCJ6.0CAHE3/57T equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 1500 W surge rating, low clamping voltage (≤10.3 V), and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamping protector using an avalanche junction structure, responding in <1 ps to transient events. Its bidirectional symmetry ensures identical electrical characteristics in both polarities, eliminating polarity concerns in AC-coupled or floating signal paths.
Thermal performance is defined by RθJA = 75 °C/W (typ.) and RθJL = 15 °C/W (typ.), enabling reliable operation up to TJ = +150 °C. The glass-passivated chip junction and matte tin-plated leads meet J-STD-002/JESD 22-B102 solderability standards and JESD 201 Class 2 whisker resistance.
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 IT = 10 mA - Ensures predictable turn-on threshold across production lot |
| VC @ IPPM | ≤10.3 V at 145.6 A - Low clamping voltage preserves downstream IC integrity during surge |
| PPPM | 1500 W (10/1000 µs waveform) - High-energy surge handling for automotive load-dump and ISO 7637-2 compliance |
| IPPM | 145.6 A - Peak surge current capacity validated under standardized test conditions |
| TJ max. | +150 °C - Enables use in under-hood automotive environments without derating |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive electronic components |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile case with matte tin-plated leads. No polarity marking - bidirectional configuration confirmed per datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | One terminal of bidirectional avalanche junction | Electrically symmetric with cathode; interchangeable in layout |
| Cathode | Other terminal of bidirectional avalanche junction | No band marking; terminals function identically in either direction |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals or floating buses without polarity constraints |

| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes voltage overshoot during clamping, reducing risk of downstream IC damage |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without moisture sensitivity concerns |
Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|
Use Scenario: Protecting analog output lines of pressure, temperature, or position sensors in engine control modules. IC Role / Device Role / Timing Role: Voltage clamping TVS placed directly at connector entry point to shunt transients before reaching ADC input or signal conditioner. Use Value: Prevents latch-up or permanent damage to precision analog front-ends during load-switching noise or battery reversal events. | Use Scenario: Safeguarding differential CAN_H/CAN_L lines against ESD and coupled surges in factory automation gateways. IC Role / Device Role / Timing Role: Bidirectional transient suppressor mounted across bus pair to clamp common-mode and differential transients simultaneously. Use Value: Maintains CAN physical layer integrity during 8 kV contact ESD (IEC 61000-4-2) and 1 kV surge (IEC 61000-4-5) without signal distortion. |
| Consumer Power Adapter Input | Telecom Line Card Surge Protection |
Use Scenario: Input-stage protection for AC-DC adapters subjected to lightning-induced surges on mains input. IC Role / Device Role / Timing Role: Primary-level TVS placed after fuse and before bridge rectifier to absorb line-to-line and line-to-ground transients. Use Value: Limits let-through voltage to <10.3 V, preventing overstress of primary-side controller ICs and bulk capacitor dielectric breakdown. | Use Scenario: Secondary-side protection of Ethernet PHY or DSL line drivers exposed to induced surges on outdoor copper pairs. IC Role / Device Role / Timing Role: Bidirectional TVS installed between transformer secondary windings and PHY interface pins. Use Value: Clamps fast-rising transients (<1 ns rise time) while maintaining signal integrity up to 100 MHz due to low junction capacitance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0CA-E3/61 | Lower PPPM = 400 W; SMA package (smaller footprint, higher RθJA = 110 °C/W) | Suitable for lower-energy surges (e.g., board-level ESD only); not rated for automotive load dump | Select when space-constrained and surge energy is limited to <400 W |
| 1.5KE6.8CA | Through-hole DO-201 package; PPPM = 1500 W; VBR = 7.14–7.89 V; no AEC-Q101 qualification | Requires wave soldering; lacks automotive qualification and SMT compatibility | Select for legacy through-hole designs where rework tolerance and manual assembly are acceptable |
Compared with SMAJ6.0CA-E3/61 and 1.5KE6.8CA, SMCJ6.0CAHE3/57T delivers automotive-grade reliability in a surface-mount package with identical 1500 W surge rating but tighter VBR tolerance and lower clamping voltage - making it optimal for new AEC-Q101-compliant designs requiring automated assembly.

FAQ
What does the "CA" suffix indicate in SMCJ6.0CAHE3/57T?
The "CA" suffix denotes a bidirectional configuration: SMCJ6.0CAHE3/57T provides symmetrical clamping in both forward and reverse directions, with identical VBR, VC, and IPPM ratings regardless of polarity. This eliminates the need for orientation-aware placement and supports AC-coupled or floating signal paths - a key distinction from unidirectional "A" variants like SMCJ6.0AHE3/57T.
Is SMCJ6.0CAHE3/57T qualified for automotive applications?
Yes, SMCJ6.0CAHE3/57T is AEC-Q101 qualified, as confirmed by Vishay's ordering code "HE3" suffix and documentation (Document Number 88394, Revision 09-Jan-2024). It undergoes stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 requirements - making it suitable for under-hood and body-control module applications.
What is the maximum clamping voltage of SMCJ6.0CAHE3/57T under surge conditions?
The maximum clamping voltage (VC) of SMCJ6.0CAHE3/57T is 10.3 V at its rated peak pulse current (IPPM) of 145.6 A, measured with a 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and forms the basis for system-level overvoltage margin calculations in designs using SMCJ6.0CAHE3/57T.
How does the SMC (DO-214AB) package of SMCJ6.0CAHE3/57T compare to SMA (DO-214AC)?
The SMC package used by SMCJ6.0CAHE3/57T measures 7.11 mm × 6.22 mm × 2.62 mm - larger than SMA (DO-214AC) - providing lower thermal resistance (RθJL = 15 °C/W vs. ~25 °C/W for SMA) and higher surge current handling. Its robust construction supports 1500 W PPPM, whereas SMA-packaged equivalents like SMAJ6.0CA are limited to 400 W.
Can SMCJ6.0CAHE3/57T be used in place of a unidirectional TVS like SMCJ6.0AHE3/57T?
SMCJ6.0CAHE3/57T can replace SMCJ6.0AHE3/57T only if the circuit is inherently bidirectional or polarity-insensitive (e.g., differential bus lines, AC-coupled sensors). It must not be substituted in unidirectional DC paths where cathode-anode orientation matters - doing so would eliminate intended forward conduction path and compromise protection. Always verify signal topology before substitution.
