Product details
Overview
SMBG6.0CA-E3/52 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for clamping ESD and surge transients on signal/power lines. It features 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 μs), <12.0 V clamping voltage (VC) at 58.3 A, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMBG6.0CA-E3/52 datasheet, SMBG6.0CA-E3/52 pinout, SMBG6.0CA-E3/52 application, or SMBG6.0CA-E3/52 equivalent, this device is selected for robust overvoltage protection in CAN/LIN bus interfaces, sensor I/O lines, and DC power rails where bidirectional clamping, low leakage (<1.0 μA at VWM), and high surge current capability are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR, VC, and IPPM specifications in either direction. Its glass-passivated junction ensures stable avalanche characteristics and low dynamic impedance under transient stress.
Designed for surface-mount assembly on 5.0 mm × 5.0 mm copper pads, it delivers 600 W peak pulse power per JEDEC-standard 10/1000 μs waveform at TA = 25 °C, with thermal resistance RθJA = 100 °C/W and maximum junction temperature of +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse working voltage before clamping begins; sets safe operating margin below system supply or signal swing. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown threshold range; ensures reliable triggering without premature conduction. |
| VC @ IPPM | 10.3 V at 58.3 A - Clamped voltage during 600 W transient; limits downstream IC stress to safe levels. |
| ID @ VWM | <1.0 μA - Ultra-low reverse leakage preserves signal integrity and battery life in always-on circuits. |
| PPPM | 600 W - Peak surge power handling per 10/1000 μs waveform; meets IEC 61000-4-5 Level 4 immunity requirements. |
| TJ max | +150 °C - Maximum junction temperature; supports operation in under-hood automotive environments. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0CA-E3/52 | Same VWM (6.0 V), but lower PPPM = 600 W (same rating), higher VC = 10.5 V at 57.1 A; SMB (DO-214AA) package, 1.6 mm taller. | Less board space efficiency due to larger SMB footprint; slightly higher clamping increases stress on protected ICs. | Select SMBJ6.0CA-E3/52 only if legacy PCB layout uses SMB pads or requires higher thermal mass. |
| 1.5SMC6.0CA | Same VWM/VBR specs, but PPPM = 1500 W; larger SMC (DO-214AB) package, RθJA = 30 °C/W. | Over-specified power handling for most 12 V systems; requires larger pad area and may complicate high-density routing. | Choose 1.5SMC6.0CA when protecting high-energy nodes like alternator feed lines or industrial motor drives. |

FAQ
What is the clamping voltage of SMBG6.0CA-E3/52 at its rated peak pulse current?
The SMBG6.0CA-E3/52 has a maximum clamping voltage (VC) of 10.3 V when subjected to its peak pulse current (IPPM) of 58.3 A under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and ensures predictable voltage limiting during surge events, directly protecting downstream 5 V logic or CAN transceivers connected to the same line.
Is SMBG6.0CA-E3/52 suitable for automotive applications?
Yes, SMBG6.0CA-E3/52 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction-including glass-passivated junction, MSL Level 1 reflow compatibility, and operation from –55 °C to +150 °C-meets stringent requirements for engine control, body electronics, and ADAS sensor protection. The SMBG6.0CA-E3/52 datasheet confirms qualification per AEC-Q101 test conditions including HTGB, H3TRB, and temperature cycling.
How does the bidirectional configuration of SMBG6.0CA-E3/52 affect its circuit placement?
The SMBG6.0CA-E3/52 has no polarity marking and functions identically in both directions, making it ideal for AC-coupled lines, differential buses (e.g., CAN, RS-485), or any node where voltage transients can occur with either polarity. Unlike unidirectional TVS diodes, SMBG6.0CA-E3/52 eliminates orientation concerns during placement and simplifies layout for symmetric protection schemes without requiring external series components.
What is the maximum reverse leakage current for SMBG6.0CA-E3/52 at its stand-off voltage?
At its rated stand-off voltage (VWM) of 6.0 V and ambient temperature of 25 °C, the SMBG6.0CA-E3/52 exhibits a maximum reverse leakage current (ID) of 1.0 μA. This ultra-low leakage preserves signal fidelity on high-impedance sensor lines and minimizes quiescent power loss in battery-powered systems-critical for maintaining accuracy and runtime in automotive and IoT edge devices using SMBG6.0CA-E3/52.
Does SMBG6.0CA-E3/52 meet RoHS and halogen-free requirements?
Yes, the SMBG6.0CA-E3/52 suffix "E3" indicates RoHS-compliant, industrial-grade construction with matte tin-plated leads. It satisfies JEDEC JESD201 Class 2 whisker resistance and UL 94 V-0 flammability for the molding compound. While not halogen-free (that designation requires "M3" suffix), SMBG6.0CA-E3/52 fully complies with EU RoHS Directive 2011/65/EU and is suitable for global commercial and automotive production.
