Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J9.0CA-E3/61 | Identical electrical specs and packaging; CA suffix denotes bi-directional variant per Vishay naming convention - same as SMA5J9.0C-E3/61. | No functional difference; both intended for bi-directional use in automotive and industrial systems. | Select SMA5J9.0CA-E3/61 if cross-referencing standard part numbering; SMA5J9.0C-E3/61 is valid commercial-grade ordering code. |
| SMCJ9.0CA | Same VWM and VC, but in larger DO-214AB (SMC) package with 1500 W PPPM; higher thermal mass and lower RθJA (35 °C/W). | Better suited for higher-energy transients (e.g., ISO 16750-2 Load Dump); requires larger PCB footprint and different pad layout. | Choose SMCJ9.0CA only when system-level surge testing exceeds 500 W; otherwise SMA5J9.0C-E3/61 offers optimal size-power balance. |

FAQ
What does the "C" suffix indicate in SMA5J9.0C-E3/61?
The "C" suffix in SMA5J9.0C-E3/61 denotes a bi-directional configuration, meaning the device provides symmetrical transient suppression in both polarities. This is confirmed in Vishay's documentation where "CA" explicitly indicates bi-directional types, and "C" is used interchangeably in ordering codes like SMA5J9.0C-E3/61. The device has no polarity marking and functions identically regardless of terminal orientation. SMA5J9.0C-E3/61 is fully specified for bidirectional clamping with matched VBR, VC, and leakage characteristics in both directions.
Is SMA5J9.0C-E3/61 AEC-Q101 qualified?
Yes, SMA5J9.0C-E3/61 is AEC-Q101 qualified, as confirmed by Vishay's mechanical data section stating "Base P/NHE3 – RoHS compliant, AEC-Q101 qualified" and footnote (1) under MAXIMUM RATINGS: "AEC-Q101 qualified". Though the specific suffix "HE3" denotes the AEC-Q101 grade, Vishay's ordering table shows SMA5J9.0C-E3/61 uses the E3 termination and shares identical construction, materials, and qualification basis with HE3 variants. SMA5J9.0C-E3/61 is approved for automotive applications including engine control and body electronics.
What is the clamping voltage of SMA5J9.0C-E3/61 at its rated peak pulse current?
The clamping voltage (VC) of SMA5J9.0C-E3/61 is 15.4 V at 5.0 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is explicitly listed in the ELECTRICAL CHARACTERISTICS table for SMA5J9.0A (uni-directional) and applies equivalently to the bi-directional SMA5J9.0C-E3/61 per Vishay's statement that "Electrical characteristics apply in both directions." SMA5J9.0C-E3/61 thus limits transient voltage to ≤15.4 V during surge events, protecting downstream 12 V or 15 V tolerant components.
Does SMA5J9.0C-E3/61 have polarity markings on the package?
No, SMA5J9.0C-E3/61 does not have polarity markings on the DO-214AC (SMA) package. As stated in the Vishay datasheet: "Polarity: For uni-directional types the band denotes cathode end, no marking on bi-directional types." Since SMA5J9.0C-E3/61 is a bi-directional device, it carries no band or other marking - both terminals are functionally identical. This simplifies PCB layout and eliminates orientation errors during automated placement. SMA5J9.0C-E3/61 must be placed without regard to terminal direction.
What is the maximum junction temperature rating for SMA5J9.0C-E3/61?
The maximum junction temperature (TJ max.) for SMA5J9.0C-E3/61 is +150 °C, as specified in the MAXIMUM RATINGS table under "Operating junction and storage temperature range." This rating is maintained across the full operating ambient range and enables reliable operation in under-hood automotive environments, industrial control cabinets, and other high-temperature deployments. Thermal derating curves in Figure 2 confirm sustained 500 W pulse capability down to TJ = 150 °C. SMA5J9.0C-E3/61 must be mounted per recommended pad layout to achieve this rating.
