Product details
Overview
SMA6J16A-M3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) 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 voltage (VBR at IT = 1 mA), 25.2 V maximum clamping voltage at 119 A (10/1000 μs), 600 W peak pulse power (10/1000 μs), and operates from –55 °C to +150 °C. It protects MOSFETs and ICs in industrial power supplies.
For engineers reviewing the SMA6J16A-M3/61 datasheet, SMA6J16A-M3/61 pinout, SMA6J16A-M3/61 application, or SMA6J16A-M3/61 equivalent, key selection criteria include clamping voltage at rated IPP, unidirectional polarity, SMA package thermal resistance (RθJA = 120 °C/W), junction temperature derating above 25 °C, and compliance with J-STD-020 MSL level 1.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (< 0.2 μA leakage at 16 V), then avalanches sharply at VBR ≥ 17.8 V to limit transient overvoltage. Its dynamic resistance (RD = 0.229 Ω) ensures low clamping overshoot during 10/1000 μs surges up to 119 A.
The device uses silicon avalanche junction technology in a planar construction, optimized for fast response (< 1 ns), low capacitance (typ. < 100 pF at VWM), and robust surge handling per IEC 61000-4-5 (4 kV line-to-line). It is rated for 50 A non-repetitive forward surge (IFSM, 8.3 ms half-sine) and requires no external bias circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before significant leakage; defines safe DC/AC working range. |
| VBR (min/max) | 17.8 V / 19.7 V at 1 mA - guaranteed avalanche onset range; sets minimum clamping threshold under surge conditions. |
| VC at IPP | 25.2 V at 119 A (10/1000 μs) - maximum clamped voltage seen by protected circuit during standardized surge event. |
| PPPM (10/1000 μs) | 600 W - peak transient energy absorption capability with standard long-duration waveform; determines surge survivability. |
| PD @ TA = 50 °C | 4 W - steady-state power dissipation limit on PCB with 5 mm × 5 mm copper pads; guides thermal layout design. |
| TJ max. | +150 °C - maximum junction temperature; enables operation in high-ambient industrial environments without derating. |
| Polarity | Unidirectional - conducts only in reverse breakdown; suitable for DC-biased lines where forward conduction must be blocked. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, halogen-free, RoHS-compliant, MSL level 1 (260 °C reflow peak), matte tin-plated leads. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to lower-potential side of protected line; completes clamping loop during reverse surge. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J16A-E3/61 | Same electrical specs; RoHS-compliant but not halogen-free; uses SnPb-free matte tin plating without whisker mitigation class 2. | Acceptable for commercial-grade products where halogen-free certification is not mandated (e.g., non-EU export units). | Select SMA6J16A-E3/61 if environmental compliance only requires RoHS, not IEC 61249-2-21 or JEDEC J-STD-609A Class 1. |
| SMCJ16A-M3 | Higher power rating: 1500 W PPPM (10/1000 μs); larger SMC (DO-214AB) package; RθJA = 35 °C/W vs. 120 °C/W. | Suitable for higher-energy surge environments (e.g., outdoor telecom cabinets), but requires more PCB area and different thermal layout. | Choose SMCJ16A-M3 only when system-level testing confirms > 600 W surge exposure; otherwise SMA6J16A-M3/61 offers optimal size/power balance. |
Compared with SMA6J16A-E3/61, the M3 suffix adds halogen-free assurance and JESD 201 class 2 whisker resistance; versus SMCJ16A-M3, SMA6J16A-M3/61 trades 2.5× lower surge rating for 60 % smaller footprint and compatibility with fine-pitch automated placement.

FAQ
What is the maximum clamping voltage of the SMA6J16A-M3/61 under a 10/1000 μs surge?
The SMA6J16A-M3/61 has a maximum clamping voltage (VC) of 25.2 V when subjected to a 119 A peak pulse current with a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 5.0 mm × 5.0 mm copper pads), and represents the highest voltage the protected circuit will experience during such a transient event. The SMA6J16A-M3/61 maintains this clamping performance across its full operating temperature range.
Does the SMA6J16A-M3/61 support bidirectional transient suppression?
No, the SMA6J16A-M3/61 is a unidirectional TVS diode and provides protection only against reverse-polarity transients on DC-biased lines. Its cathode band marks the terminal that connects to the higher-potential side of the circuit. For AC or bipolar signal line protection, a bidirectional variant (e.g., SMA6J16CA) would be required-not the SMA6J16A-M3/61.
What is the thermal resistance of the SMA6J16A-M3/61, and how does it affect PCB layout?
The SMA6J16A-M3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on PCBs with 5.0 mm × 5.0 mm copper pads per terminal. This value assumes standard JEDEC test conditions; reducing pad size or omitting thermal vias increases RθJA, risking junction overheating during repeated surges. Layout must maintain minimum pad dimensions and consider copper area for sustained 4 W power dissipation at TA = 50 °C.
Is the SMA6J16A-M3/61 compliant with moisture sensitivity level (MSL) requirements for lead-free reflow?
Yes, the SMA6J16A-M3/61 meets MSL level 1 per J-STD-020, with a maximum lead-free reflow peak temperature of 260 °C. This means the device can be stored indefinitely at ambient conditions and placed directly into reflow ovens without baking or dry-pack requirements-reducing manufacturing complexity and cost for high-volume SMT lines.
How does the halogen-free designation (M3 suffix) impact the material composition of the SMA6J16A-M3/61?
The M3 suffix indicates the SMA6J16A-M3/61 uses halogen-free molding compound and terminations, complying with IEC 61249-2-21 and JEDEC J-STD-609A Class 1. Bromine and chlorine content are each limited to < 900 ppm, and total halogens < 1500 ppm-reducing toxic gas emission during board recycling or fire events. This differs from the E3 version, which is RoHS-compliant but not halogen-free.
