Product details
Overview
SMCJ6.0CA-E3/9AT from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on signal or power lines. It features 6.0 V standoff voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 1500 W peak pulse power (10/1000 μs), and clamps to ≤10.3 V at 145.6 A peak surge current - used in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the SMCJ6.0CA-E3/9AT datasheet, SMCJ6.0CA-E3/9AT pinout, SMCJ6.0CA-E3/9AT application, or SMCJ6.0CA-E3/9AT equivalent, key selection criteria include bidirectional clamping capability, 1500 W surge rating, RoHS-compliant matte tin terminals, MSL Level 1 moisture sensitivity, 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 with symmetrical avalanche behavior in both directions, enabling robust transient suppression without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance under repetitive 10/1000 μs surges.
Thermal performance is defined by RθJA = 75 °C/W and RθJL = 15 °C/W, supporting reliable operation up to TJ = +150 °C. The SMC (DO-214AB) package meets UL 94 V-0 flammability and JESD201 Class 2 whisker resistance standards.
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 - guaranteed breakdown window defining turn-on threshold tolerance |
| VC @ IPPM | ≤10.3 V at 145.6 A - clamped voltage during full 1500 W surge, limiting stress on downstream ICs |
| PPPM | 1500 W - peak pulse power handling per 10/1000 μs waveform, critical for lightning/inductive spike immunity |
| ID @ VWM | ≤1000 μA - low leakage ensures minimal standby power loss and signal integrity in high-impedance circuits |
| TJ max. | +150 °C - enables use in under-hood automotive and industrial environments with elevated ambient temperatures |
| Package | SMC (DO-214AB) - standardized surface-mount outline with 0.320" body length and 0.246" width for automated assembly |
Pinout & Package
SMCJ6.0CA-E3/9AT uses the SMC (DO-214AB) package: a bidirectional device with no polarity marking; both terminals are electrically symmetric and interchangeable. Mounting requires 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal for rated thermal and surge performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals conduct identically during positive or negative transients - no orientation required during placement |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| 1500 W peak pulse power | Withstands IEC 61000-4-5 Level 4 (4 kV surge) when properly mounted on recommended PCB copper area |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes overvoltage exposure to protected ICs compared to higher-ratio suppressors |
| MSL Level 1, 260 °C reflow compatible | Supports standard lead-free SMT reflow profiles without preconditioning or baking |
| RoHS-compliant matte tin plating | Ensures solderability per J-STD-002 and long-term reliability in humid or thermally cycled environments |

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-TB | Lower PPPM (500 W), same VWM (5.0 V), smaller SMA package (DO-214AC) | Not suitable for IEC 61000-4-5 Level 4; limited to lower-energy transients in space-constrained consumer designs | Select when board area is critical and surge threat level is ≤1 kV; verify thermal derating for 85 °C ambient |
| SMCJ6.0A-E3/9AT | Unidirectional version with cathode band marking; identical VWM, VBR, and PPPM but asymmetric conduction | Requires correct polarity alignment; unsuitable for AC or floating signals where bidirectional clamping is mandatory | Choose only for DC-biased lines with known polarity (e.g., 5 V supply rail); avoid in differential or AC-coupled paths |
Compared with SAC5.0CA-TB and SMCJ6.0A-E3/9AT, the SMCJ6.0CA-E3/9AT uniquely delivers 1500 W bidirectional clamping in SMC package - essential for automotive and industrial interfaces where polarity uncertainty and high-energy transients coexist.

FAQ
What does the "CA" suffix indicate in SMCJ6.0CA-E3/9AT?
The "CA" suffix denotes a bidirectional configuration - meaning the SMCJ6.0CA-E3/9AT provides symmetrical clamping for both positive and negative voltage transients without polarity dependency. Unlike unidirectional variants (e.g., SMCJ6.0A), it has no cathode band marking and is used where signal lines may experience AC-coupled or floating conditions, such as RS-485 buses or sensor bridges. This makes SMCJ6.0CA-E3/9AT ideal for applications requiring polarity-agnostic surge protection.
Is SMCJ6.0CA-E3/9AT AEC-Q101 qualified?
No - SMCJ6.0CA-E3/9AT is RoHS-compliant commercial-grade with E3 suffix, not AEC-Q101 qualified. For automotive-grade versions, Vishay offers SMCJ6.0CAHE3_X (e.g., SMCJ6.0CAHE3_A), which carries the HE3 suffix and meets AEC-Q101 stress test requirements. The SMCJ6.0CA-E3/9AT remains suitable for industrial and telecom applications where extended temperature range (−55 °C to +150 °C) and 1500 W surge capability are primary needs, but not for safety-critical automotive subsystems requiring formal qualification.
What is the recommended PCB pad layout for SMCJ6.0CA-E3/9AT to achieve rated 1500 W performance?
To achieve the full 1500 W peak pulse power rating, Vishay specifies mounting SMCJ6.0CA-E3/9AT on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal - minimum dimensions per datasheet Figure 2 and Table "Maximum Ratings". Smaller pads cause thermal derating; at 75 °C ambient, power dissipation drops significantly. Use internal ground/power planes connected via multiple thermal vias under each pad to enhance heat spreading. The SMCJ6.0CA-E3/9AT must be placed as close as possible to the protected interface connector to minimize inductance in the surge path.
How does the clamping voltage VC of SMCJ6.0CA-E3/9AT compare to its breakdown voltage VBR?
For SMCJ6.0CA-E3/9AT, VBR is specified as 6.67–7.37 V at 10 mA, while VC is ≤10.3 V at 145.6 A - yielding a clamping ratio (VC/VBR) of approximately 1.44. This low ratio indicates efficient energy diversion with minimal overvoltage overshoot. In practice, this means that when a 145.6 A transient hits the device, downstream circuitry sees no more than 10.3 V, well below typical 12 V or 15 V IC absolute maximum ratings - a key advantage of SMCJ6.0CA-E3/9AT over higher-ratio suppressors in sensitive analog or mixed-signal domains.
Can SMCJ6.0CA-E3/9AT replace SMCJ6.0A-E3/9AT in an existing design?
SMCJ6.0CA-E3/9AT can replace SMCJ6.0A-E3/9AT only if the circuit is inherently bidirectional or polarity-independent - for example, across differential pairs or floating sensors. However, it cannot substitute in unidirectional applications like 5 V supply rail clamping, where the cathode band of SMCJ6.0A-E3/9AT ensures correct orientation and prevents forward conduction during normal operation. Since SMCJ6.0CA-E3/9AT lacks polarity marking and conducts equally in both directions, using it in place of SMCJ6.0A-E3/9AT on a DC rail could cause unintended current flow. Always verify signal topology before substitution.
