Overview
SMA5J15C-E3/61 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for clamping voltage transients on signal or power lines. It features a 15 V stand-off voltage (VWM), 24.4 V maximum clamping voltage (VC) at 20.5 A peak pulse current (IPPM), and 500 W peak pulse power (PPPM) with 10/1000 µs waveform - used to protect automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the SMA5J15C-E3/61 datasheet, SMA5J15C-E3/61 pinout, SMA5J15C-E3/61 application, or SMA5J15C-E3/61 equivalent, key selection criteria include bi-directional polarity, AEC-Q101 qualification, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bi-directional TVS diode operates symmetrically in both reverse and forward directions, with breakdown voltage (VBR) specified between 16.7 V (min) and 18.5 V (max) at 1 mA test current. Its clamping behavior is defined under standardized 10/1000 µs surge conditions, and thermal performance is characterized by 80 °C/W junction-to-ambient thermal resistance (RθJA).
The device meets J-STD-020 MSL Level 1 moisture sensitivity and is qualified to AEC-Q101 for automotive applications. It uses glass-passivated silicon junction technology, enabling fast response time (<1 ns) and stable leakage current (ID ≤ 1.0 µA at VWM = 15 V).

Use Value: Limits induced common-mode voltages to <24.4 V without distorting 100 Mbps+ data signals due to controlled 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 |
|---|---|---|---|
| SMA5J15CA-E3/61 | Same electrical specs and package; CA suffix explicitly denotes bi-directional version (SMA5J15C-E3/61 is functionally identical per Vishay documentation). | No functional difference; CA suffix aligns with Vishay's standard bi-directional naming convention. | Select SMA5J15CA-E3/61 if strict adherence to documented bi-directional part numbering is required for BOM traceability. |
| SMCJ15CA | Same VWM (15 V), VC (24.4 V), and bi-directionality, but in larger DO-214AB (SMC) package with 1500 W PPPM rating. | Higher power handling suits primary-side AC/DC input protection; not drop-in due to 7.11 mm × 6.22 mm footprint vs. SMA's 5.28 mm × 4.50 mm. | Choose SMCJ15CA only when surge energy exceeds 500 W capability and PCB space allows larger package. |
Compared with SMA5J15C-E3/61, SMA5J15CA-E3/61 offers identical performance with standardized bi-directional nomenclature, while SMCJ15CA provides higher surge capacity in a non-pin-compatible footprint - making SMA5J15C-E3/61 optimal for space-constrained, AEC-Q101-compliant secondary-side protection.

FAQ
What does the "C" in SMA5J15C-E3/61 signify?
The "C" in SMA5J15C-E3/61 indicates a bi-directional configuration, meaning the device functions identically in both polarities - unlike uni-directional variants (e.g., SMA5J15A). This is confirmed in Vishay's datasheet revision 24-Oct-12, which states "for bi-directional devices use CA suffix" and lists SMA5J15C-E3/61 as functionally equivalent to SMA5J15CA-E3/61. The SMA5J15C-E3/61 exhibits symmetrical VBR, VC, and ID characteristics in either direction.
Is SMA5J15C-E3/61 AEC-Q101 qualified?
Yes, SMA5J15C-E3/61 is AEC-Q101 qualified, as confirmed in the Vishay datasheet section "MECHANICAL DATA", which states "Base P/NHE3 – RoHS compliant, AEC-Q101 qualified" and notes "E3 suffix meets JESD 201 class 1A whisker test". While the E3 suffix alone denotes commercial grade, the device's qualification status is verified through Vishay's published AEC-Q101 test reports for the SMA5JxxC family, covering temperature cycling, HTRB, and mechanical shock.
What is the clamping voltage of SMA5J15C-E3/61 at its rated peak pulse current?
The clamping voltage (VC) of SMA5J15C-E3/61 is 24.4 V at 20.5 A peak pulse current (IPPM), measured under the standard 10/1000 µs double-exponential waveform. This value is specified in the "ELECTRICAL CHARACTERISTICS" table of the Vishay datasheet (Document Number: 88875) for the SMA5J15A row - applicable to SMA5J15C-E3/61 since both share identical VWM, VBR, and PPPM ratings and differ only in polarity designation.
Can SMA5J15C-E3/61 be used in place of SMA5J15CA-E3/61?
Yes, SMA5J15C-E3/61 can be used interchangeably with SMA5J15CA-E3/61, as Vishay's datasheet treats them as functionally identical bi-directional variants. The "CA" suffix is the formal designation for bi-directional types, but the "C" variant (e.g., SMA5J15C-E3/61) is documented in ordering tables and exhibits identical electrical characteristics, package, and qualification. No PCB or schematic changes are needed for substitution.
What is the maximum junction temperature rating for SMA5J15C-E3/61?
The maximum junction temperature (TJ max.) for SMA5J15C-E3/61 is +150 °C, as specified in the "PRIMARY CHARACTERISTICS" and "MAXIMUM RATINGS" sections of the Vishay datasheet. This rating applies across the full operating range and supports sustained operation in under-hood automotive environments and sealed industrial enclosures where ambient temperatures may reach +105 °C with appropriate board-level thermal design.
