Product details
Overview
SMCJ6.0A-E3/57T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of DC power rails and signal lines. 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), 10.3 V clamping voltage at 145.6 A peak surge current, and operates across –55 °C to +150 °C junction temperature range - deployed in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the SMCJ6.0A-E3/57T datasheet, SMCJ6.0A-E3/57T pinout, SMCJ6.0A-E3/57T application, or SMCJ6.0A-E3/57T equivalent, key selection criteria include verified clamping performance under 10/1000 µs transients, unidirectional polarity marking (cathode band), RoHS-compliant matte tin terminations, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ6.0A-E3/57T uses a glass-passivated silicon junction optimized for low incremental surge resistance and sub-nanosecond response time to ESD and lightning-induced transients. Its unidirectional configuration provides forward conduction only during reverse overvoltage events, with cathode-band polarity identification and no reverse leakage above 1000 µA at 6.0 V stand-off.
Thermal design relies on RθJA = 75 °C/W (typ.) and RθJL = 15 °C/W (typ.), requiring minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal for rated 1500 W pulse handling. It meets AEC-Q101 qualification when ordered with HE3 suffix, but the -E3/57T variant is commercial-grade RoHS-compliant per JESD201 Class 2 whisker test.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe DC rail margin for 5 V systems. |
| VBR min/max | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown threshold ensures reliable turn-on during fast transients without premature conduction. |
| VC @ IPPM | 10.3 V at 145.6 A - Clamped voltage during 10/1000 µs surge limits downstream IC stress to safe levels. |
| PPPM | 1500 W - Peak pulse power rating determines survivability against IEC 61000-4-5 Level 4 surges (4 kV line-earth). |
| ID @ VWM | 1000 µA max - Low reverse leakage preserves efficiency in battery-powered or high-impedance sensor circuits. |
| TJ range | –55 °C to +150 °C - Enables deployment in under-hood automotive or industrial ambient environments. |
| Package | SMC (DO-214AB) - Standardized 2-pin surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height. |
Pinout & Package
SMCJ6.0A-E3/57T is housed in an SMC (DO-214AB) plastic package with matte tin-plated leads solderable per J-STD-002 and JESD22-B102. Polarity is marked by a cathode band on the case end; the banded terminal is the cathode (K), and the opposite terminal is the anode (A). No marking is present on bidirectional variants, but this part is unidirectional.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive reference terminal | Connected to protected circuit's ground or low-side return path; forms forward-biased path during surge conduction. |
| Cathode (K) | Negative reference terminal (banded end) | Connected to protected line (e.g., 5 V rail); reverse-biased during normal operation, avalanches during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SMC package | Enables high-density PCB layouts and compatibility with standard pick-and-place equipment for automated manufacturing. |
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure. |
| 1500 W peak pulse power | Withstands repeated 10/1000 µs surges up to 145.6 A without degradation-validated per IEC 61000-4-5. |
| MSL Level 1 rating | Allows unlimited floor life and reflow at 260 °C peak without baking, simplifying SMT assembly logistics. |
| RoHS-compliant matte tin leads | Meets JESD201 Class 2 whisker resistance and supports lead-free reflow profiles without intermetallic growth issues. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC5.0A-TB | Lower PPPM (500 W), higher VBR (6.4–7.2 V), DO-214AC (SMA) package - smaller footprint but lower surge capacity. | Best suited for space-constrained consumer electronics where 500 W surge immunity suffices. | Select SAC5.0A-TB only if board area is critical and peak surge energy remains below 500 W. |
| 1.5SMC6.0A | Identical electrical specs (VWM = 6.0 V, VC = 10.3 V, PPPM = 1500 W), same SMC package, but legacy Vishay marking and older revision status. | Functionally interchangeable in new designs; may be preferred for legacy BOM continuity or cost-sensitive procurement. | Choose 1.5SMC6.0A when sourcing legacy-qualified stock or aligning with existing design documentation referencing that base P/N. |
Compared with SAC5.0A-TB, SMCJ6.0A-E3/57T delivers 3× higher surge power handling and larger thermal mass; versus 1.5SMC6.0A, it offers updated RoHS/E3 compliance and documented MSL Level 1 reflow support - making it optimal for automotive and industrial production programs requiring full traceability and process assurance.

FAQ
What is the maximum clamping voltage of the SMCJ6.0A-E3/57T during a 10/1000 µs surge?
The SMCJ6.0A-E3/57T has a maximum clamping voltage (VC) of 10.3 V when subjected to its rated peak pulse current of 145.6 A under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet revision 09-Jan-2024. The clamping performance ensures downstream components see no more than 10.3 V during worst-case surge events, making SMCJ6.0A-E3/57T suitable for protecting 5 V logic rails and sensitive analog interfaces.
Is the SMCJ6.0A-E3/57T RoHS-compliant and halogen-free?
Yes, the SMCJ6.0A-E3/57T carries the "E3" suffix, indicating it is RoHS-compliant per EU Directive 2011/65/EU and meets Vishay's material categorization standards. However, it is not halogen-free - that designation requires the "M3" suffix (e.g., SMCJ6.0A-M3/57T). The E3 variant uses matte tin-plated leads qualified to JESD201 Class 2 for whisker resistance and is rated MSL Level 1 for reflow compatibility. SMCJ6.0A-E3/57T is intended for commercial-grade applications where full halogen-free compliance is not mandated.
Does the SMCJ6.0A-E3/57T have AEC-Q101 qualification?
No, the SMCJ6.0A-E3/57T is not AEC-Q101 qualified. That qualification applies only to variants with the "HE3" or "HM3" suffix (e.g., SMCJ6.0AHE3_A/H). The -E3/57T version is commercial-grade and certified for MSL Level 1, RoHS compliance, and JESD201 Class 2 whisker resistance - sufficient for industrial and consumer applications. For automotive under-hood or safety-critical use, engineers must specify SMCJ6.0AHE3_X to obtain AEC-Q101 documentation and testing evidence. SMCJ6.0A-E3/57T remains appropriate for non-automotive 5 V rail protection where qualification is not required.
What is the thermal resistance from junction to ambient for the SMCJ6.0A-E3/57T?
The typical thermal resistance from junction to ambient (RθJA) for SMCJ6.0A-E3/57T is 75 °C/W, measured under standard conditions using 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes no additional heatsinking and defines the steady-state temperature rise per watt of dissipated power. For pulsed operation, transient thermal impedance curves (Fig. 5 in the datasheet) govern short-duration surge handling. Designers must verify layout adherence to the recommended pad dimensions to achieve rated 1500 W pulse performance - undersized pads will elevate RθJA and reduce surge capability. SMCJ6.0A-E3/57T's RθJL is 15 °C/W, supporting efficient heat transfer to PCB copper.
How is polarity identified on the SMCJ6.0A-E3/57T package?
Polarity on the SMCJ6.0A-E3/57T is indicated by a visible cathode band printed on one end of the SMC (DO-214AB) case. The banded terminal is the cathode (K), and the opposite terminal is the anode (A). This marking is essential for correct unidirectional installation: the cathode connects to the line being protected (e.g., 5 V rail), and the anode connects to ground. Bidirectional variants (e.g., SMCJ6.0CA) omit this band, but SMCJ6.0A-E3/57T is strictly unidirectional. Misorientation results in forward conduction during normal operation - causing excessive leakage and potential circuit malfunction. Always verify band alignment before reflow, as SMCJ6.0A-E3/57T has no alternate marking scheme.
