Product details
Overview
SMAJ16C-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 16 V stand-off voltage (VWM), 28.8 V maximum clamping voltage (VC) at 13.9 A peak pulse current (IPPM), and 400 W peak pulse power rating with 10/1000 µs waveform - suitable for protecting MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the SMAJ16C-E3/61 datasheet, SMAJ16C-E3/61 pinout, SMAJ16C-E3/61 application, or SMAJ16C-E3/61 equivalent, key selection criteria include bi-directional surge clamping capability, low leakage (<1 µA at 16 V), RoHS-compliant matte tin terminals, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on standard PCB copper pads.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with breakdown voltage (VBR) specified between 17.8 V (min) and 21.8 V (max) at 1 mA test current. Its clamping behavior is characterized under standardized 10/1000 µs surge conditions, delivering consistent VC ≤ 28.8 V up to IPPM = 13.9 A.
Thermal performance is defined by RθJA = 120 °C/W (typ.) and RθJL = 30 °C/W (typ.), supporting operation from –55 °C to +150 °C junction temperature. The device meets JESD201 Class 1A whisker resistance and is rated for solder dip at 260 °C for 40 s.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse working voltage before clamping initiates |
| VC @ IPPM | 28.8 V - Clamped voltage across device during 13.9 A 10/1000 µs surge, limiting downstream stress |
| IPPM | 13.9 A - Peak surge current handled without failure under standard waveform |
| PPPM | 400 W - Peak pulse power dissipation capability, derated above 78 V |
| ID @ VWM | <1 µA - Reverse leakage ensures minimal standby power loss and signal integrity |
| TJ Range | –55 °C to +150 °C - Enables use in under-hood automotive and industrial ambient environments |
Pinout & Package
DO-214AC (SMA) surface-mount package with two terminals: anode and cathode. Bi-directional configuration means no polarity marking; terminals are functionally symmetrical.
| Pin/Terminal | Circuit Role | Design Meaning |

| Cathode | Current exit point in forward bias; common node in bi-directional clamping | Connected to protected line; completes symmetrical clamping path with anode |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping | Protects AC-coupled or floating signal lines without polarity constraints |
| Glass passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling |
| MSL Level 1 rating | Allows unlimited floor life and reflow without baking prior to assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16CA-E3/61 | Identical electrical specs and packaging; CA suffix denotes same bi-directional variant per Vishay nomenclature | No functional difference - CA and C suffixes are interchangeable per Vishay documentation for this family | Select based on distributor stock; both meet identical AEC-Q101 and RoHS requirements |
| SMBJ16C-E3/52 | Same VWM (16 V) and VC (28.8 V), but in larger DO-214AA (SMB) package with higher IPPM (21.5 A) and PPPM (600 W) | Better suited for higher-energy transients; requires larger PCB pad area and different thermal layout | Choose SMBJ16C-E3/52 only when system-level testing confirms need for >400 W surge margin |
Compared with SMAJ16C-E3/61, SMAJ16CA-E3/61 offers identical protection performance in the same footprint, while SMBJ16C-E3/52 provides higher surge capacity at the cost of board space - making SMAJ16C-E3/61 optimal for space-constrained 16 V rail protection where 400 W rating suffices.

FAQ
What is the clamping voltage of SMAJ16C-E3/61 under a 10/1000 µs surge?
The SMAJ16C-E3/61 clamps to a maximum of 28.8 V when subjected to its rated peak pulse current of 13.9 A using the standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and reflects worst-case VC measured per ANSI/IEEE C62.35. The SMAJ16C-E3/61 achieves this with low incremental resistance, minimizing overshoot during fast transients.
Is SMAJ16C-E3/61 suitable for automotive applications?
Yes, SMAJ16C-E3/61 meets AEC-Q101 qualification requirements for automotive-grade discrete semiconductors. Its –55 °C to +150 °C operating junction temperature range, MSL Level 1 rating, and JESD201 Class 1A whisker resistance make it appropriate for engine control units, body electronics, and ADAS sensor modules. The SMAJ16C-E3/61 is explicitly listed in Vishay's AEC-Q101 qualified devices table.
How does the bi-directional configuration of SMAJ16C-E3/61 affect PCB layout?
The SMAJ16C-E3/61 has no polarity marking and functions identically in both directions, simplifying PCB layout by eliminating orientation checks during automated placement. Layout requires symmetric 0.2 × 0.2 inch copper pads per terminal to sustain its 400 W pulse rating, and no ground plane isolation is needed beyond standard high-voltage creepage. The SMAJ16C-E3/61's DO-214AC footprint remains unchanged versus uni-directional variants.
What is the maximum reverse leakage current for SMAJ16C-E3/61 at its rated stand-off voltage?
At its 16 V stand-off voltage (VWM) and 25 °C ambient temperature, the SMAJ16C-E3/61 exhibits a maximum reverse leakage current (ID) of 1 µA. This low leakage preserves signal integrity in high-impedance sensor circuits and minimizes quiescent power loss in battery-powered systems. The SMAJ16C-E3/61 maintains this specification across its full operating temperature range per derating curves in the datasheet.
Does SMAJ16C-E3/61 require special handling or baking before reflow soldering?
No - SMAJ16C-E3/61 is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and may be placed directly into reflow without pre-baking. Its moisture sensitivity is mitigated by the DO-214AC molding compound and glass passivation. The SMAJ16C-E3/61 supports peak reflow temperatures up to 260 °C for 40 seconds, fully compatible with standard lead-free solder profiles.
