Product details
Overview
SMA5J16C-E3/5A from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for clamping voltage transients on power and signal lines. It features a 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown range (VBR), 500 W peak pulse power (10/1000 µs), 19.2 A peak pulse current (IPPM), and 26.0 V maximum clamping voltage (VC) - deployed in automotive sensor protection and industrial I/O interfaces.
For engineers reviewing the SMA5J16C-E3/5A datasheet, SMA5J16C-E3/5A pinout, SMA5J16C-E3/5A application, or SMA5J16C-E3/5A equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, 150 °C junction temperature rating, RoHS-compliant matte tin terminations, 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 polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, enabling consistent clamping under repetitive transients induced by inductive switching or ESD events.
The device meets MSL Level 1 per J-STD-020 (peak reflow ≤ 260 °C) and is qualified to AEC-Q101 for automotive use. Thermal resistance is 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead), supporting reliable operation up to TJ = 150 °C when mounted per recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse stand-off voltage before clamping begins; defines safe operating window for protected circuitry. |
| VBR min/max | 17.8 V / 19.7 V at 1 mA - Verified breakdown threshold range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 26.0 V at 19.2 A - Clamped voltage during 10/1000 µs surge; limits stress on downstream ICs like microcontrollers or CAN transceivers. |
| PPPM | 500 W - Peak pulse power handling capacity; supports robust protection against ISO 7637-2 Load Dump and IEC 61000-4-5 surges. |
| TJ max | 150 °C - Maximum junction temperature; enables deployment in under-hood automotive environments and industrial enclosures. |
| Package | DO-214AC (SMA) - Surface-mount package with 5.28 mm × 4.50 mm footprint; compatible with standard SMT pick-and-place and reflow processes. |
Pinout & Package
DO-214AC (SMA) package: bi-directional device with no polarity marking; two terminals - anode and cathode are functionally interchangeable due to symmetrical construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | One side of bi-directional PN junction | Connects to line being protected; no fixed polarity - either terminal may be assigned to input or return path. |
| Cathode | Other side of bi-directional PN junction | Functionally identical to anode; enables clamping in both directions without orientation constraints on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing. |
| Glass passivated junction | Enhances long-term stability and reduces parameter drift under thermal stress and high-humidity operating conditions. |
| MSL Level 1 rating | Enables single-pass reflow without moisture-related defects; no baking required prior to assembly. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ESD > 15 kV), improving protection margin for sensitive analog inputs. |
| RoHS-compliant matte tin plating | Ensures solderability per J-STD-002 and whisker resistance per JESD 201 Class 1A (E3 suffix). |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J16CA-E3/5A | Identical electrical specs and packaging; CA suffix explicitly denotes bi-directional configuration (same as C in SMA5J16C-E3/5A). | No functional difference; used interchangeably in design documentation and BOMs where bi-directional marking convention varies. | Select SMA5J16CA-E3/5A if internal part numbering standards require explicit "CA" suffix for bi-directional variants. |
| 1.5KE16CA | Through-hole DO-201 package; same VWM/VC but higher RθJA (70 °C/W), lower IPPM (22.5 A), and 1500 W PPPM (10/1000 µs). | Used in legacy through-hole designs or high-energy surge paths where board space allows larger footprint and thermal mass. | Choose 1.5KE16CA only when SMT assembly is unavailable or when higher peak power (but slower response) is prioritized over board density. |
Compared with SMA5J16C-E3/5A, SMA5J16CA-E3/5A offers identical performance in identical packaging, while 1.5KE16CA trades surface-mount compatibility and faster response for higher absolute surge energy handling in through-hole form - making the former ideal for modern automotive and industrial SMT platforms.

FAQ
What does the "C" in SMA5J16C-E3/5A signify?
The "C" in SMA5J16C-E3/5A indicates a bi-directional configuration - confirmed by Vishay's ordering nomenclature and electrical specifications showing symmetrical VBR, VC, and leakage behavior in both polarities. This distinguishes it from uni-directional variants (e.g., SMA5J16A-E3/5A) and ensures clamping action regardless of voltage polarity across the SMA5J16C-E3/5A terminals.
Is SMA5J16C-E3/5A RoHS compliant and lead-free?
Yes, SMA5J16C-E3/5A is RoHS compliant and lead-free, as indicated by the "E3" suffix per Vishay's ordering information and material categorization documentation. The matte tin-plated leads meet J-STD-002 solderability requirements and JESD 201 Class 1A whisker resistance testing, ensuring reliability in lead-free reflow processes.
What is the maximum clamping voltage of SMA5J16C-E3/5A under surge conditions?
The maximum clamping voltage (VC) of SMA5J16C-E3/5A is 26.0 V at 19.2 A peak pulse current (IPPM) under a 10/1000 µs waveform, per Vishay's Electrical Characteristics table. This value represents the upper limit of voltage seen by protected circuitry during worst-case transient events.
Does SMA5J16C-E3/5A require polarity-aware PCB layout?
No - SMA5J16C-E3/5A is a bi-directional TVS diode with no polarity marking on the DO-214AC (SMA) package. Both terminals are functionally identical, allowing flexible placement on PCBs without orientation constraints, unlike uni-directional variants that require cathode band alignment.
What is the junction-to-ambient thermal resistance of SMA5J16C-E3/5A?
The typical junction-to-ambient thermal resistance (RθJA) of SMA5J16C-E3/5A is 80 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Vishay's Thermal Characteristics table. This value assumes standard JEDEC test conditions and guides thermal design for sustained surge duty cycles.
