Product details
Overview
SMA5J7.0C-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 and power lines. It features a 7.0 V stand-off voltage (VWM), 12.0 V maximum clamping voltage at 41.7 A peak pulse current, and 500 W peak pulse power dissipation with 10/1000 μs waveform - used to protect automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the SMA5J7.0C-E3/61 datasheet, SMA5J7.0C-E3/61 pinout, SMA5J7.0C-E3/61 application, or SMA5J7.0C-E3/61 equivalent, key selection criteria include bi-directional polarity, AEC-Q101 qualification, MSL Level 1 rating, 150 °C max junction temperature, 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 7.78 V and 8.60 V at 10 mA test current. Its low incremental surge resistance and fast response time enable effective suppression of ESD, lightning-induced surges, and inductive switching transients.
The device uses a glass-passivated silicon junction and meets UL 94 V-0 flammability requirements. Thermal resistance is 80 °C/W junction-to-ambient (typical) and 25 °C/W junction-to-lead, supporting reliable operation under repetitive surge conditions when mounted per recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - Maximum continuous reverse stand-off voltage before clamping begins; defines safe operating window for protected circuitry. |
| VBR min/max | 7.78 V / 8.60 V at 10 mA - Confirmed breakdown range ensures predictable turn-on behavior across production lots. |
| VC @ IPPM | 12.0 V at 41.7 A - Clamping voltage during 10/1000 μs surge; determines maximum stress imposed on downstream ICs. |
| PPPM | 500 W - Peak pulse power handling capability with standard 10/1000 μs waveform; validates robustness against IEC 61000-4-5 surges. |
| TJ max | +150 °C - Maximum junction temperature rating enables use in under-hood automotive and high-temperature industrial environments. |
| Polarity | Bi-directional - No cathode marking; symmetrical clamping in both polarities simplifies PCB layout for AC-coupled or floating signal lines. |
| MSL Level | Level 1 (per J-STD-020) - Supports standard reflow profiles up to 260 °C peak without moisture-related damage. |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, molded plastic case with matte tin-plated leads. Complies with UL 94 V-0 flammability rating and J-STD-002/JESD 22-B102 solderability standards. Bi-directional types have no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (unmarked) | Bi-directional transient conduction path | Both terminals function identically; clamps voltage excursions above ±12.0 V regardless of polarity - eliminates orientation concerns during placement. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J7.0CA-E3/61 | Same electrical specs and package; CA suffix explicitly denotes bi-directional version (SMA5J7.0C-E3/61 is functionally identical per Vishay documentation). | No functional difference; both intended for bi-directional use in automotive and industrial systems. | Select SMA5J7.0C-E3/61 when ordering per standard Vishay part numbering convention for bi-directional variants. |
| SMCJ7.0CA | Higher 1500 W PPPM rating in larger DO-214AB (SMC) package; same 7.0 V VWM and bi-directional polarity. | Better suited for higher-energy surge environments (e.g., main power input stages); requires larger PCB footprint. | Choose SMCJ7.0CA only if system-level testing confirms need for >500 W surge handling; otherwise SMA5J7.0C-E3/61 offers optimal power density. |
Compared with SMA5J7.0CA-E3/61, the SMA5J7.0C-E3/61 is identical in specification and form; versus SMCJ7.0CA, it trades lower surge capacity for 60 % smaller board area and full AEC-Q101 qualification - making it preferred for space-constrained automotive sensor nodes.

This behavior is confirmed in Vishay's Electrical Characteristics table for "CA"-suffix devices.
Does SMA5J7.0C-E3/61 meet automotive qualification standards?
Yes, SMA5J7.0C-E3/61 is AEC-Q101 qualified, as documented in Vishay's datasheet revision 24-Oct-12. This qualification validates its suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces, covering stress tests for temperature cycling, humidity, mechanical shock, and surge endurance under defined automotive operating conditions.
What is the maximum clamping voltage for SMA5J7.0C-E3/61 under surge conditions?
The SMA5J7.0C-E3/61 has a maximum clamping voltage (VC) of 12.0 V at 41.7 A peak pulse current, measured using the standard 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and is verified per ANSI/IEEE C62.35 standards - ensuring compatibility with 5 V and 12 V logic interfaces.
Is SMA5J7.0C-E3/61 compatible with lead-free reflow processes?
Yes, SMA5J7.0C-E3/61 carries the "E3" suffix indicating RoHS compliance and qualification for lead-free soldering. It meets J-STD-020 MSL Level 1 with a maximum peak reflow temperature of 260 °C, allowing direct placement into standard Pb-free reflow ovens without pre-baking - simplifying manufacturing for high-volume automotive and industrial PCB assembly.
How does the DO-214AC (SMA) package of SMA5J7.0C-E3/61 impact thermal performance?
The DO-214AC (SMA) package delivers a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W and junction-to-lead resistance (RθJL) of 25 °C/W. When mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, this enables sustained operation at +150 °C junction temperature - supporting reliability in under-hood automotive and enclosed industrial enclosures.
