Product details
Overview
SMA6J16A-M3/5A from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in SMA (DO-214AC) package, rated for 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR at IT = 1 mA), and 25.2 V maximum clamping voltage (VC) at 119 A peak pulse current (IPP, 10/1000 µs). It delivers 600 W peak pulse power and protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the SMA6J16A-M3/5A datasheet, SMA6J16A-M3/5A pinout, SMA6J16A-M3/5A application, or SMA6J16A-M3/5A equivalent, key selection criteria include clamping voltage margin vs. protected device VDS/VCC, unidirectional polarity compatibility with DC-biased lines, thermal resistance (RθJA = 120 °C/W), and halogen-free RoHS compliance per M3 suffix.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias (≤16 V), leakage remains ≤0.2 µA; during transient events, it avalanches at ≥17.8 V and clamps to ≤25.2 V at 119 A (10/1000 µs), limiting energy dissipation to 600 W. Its dynamic resistance (RD = 0.229 Ω) ensures low voltage overshoot during fast surges.
Designed for PCB-level protection of DC power rails and signal lines, it features MSL Level 1 moisture sensitivity, matte tin-plated leads compliant with J-STD-002, and a junction temperature range of −55 °C to +150 °C. The SMA package enables automated placement and meets UL 94 V-0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse operating voltage before leakage exceeds 0.2 µA; sets upper limit for protected line DC bias. |
| VBR (min/max) | 17.8 V / 19.7 V at 1 mA - Ensures reliable avalanche initiation above system operating voltage with 1.8 V design margin. |
| VC @ IPP | 25.2 V at 119 A (10/1000 µs) - Clamping level must stay below protected device absolute maximum rating (e.g., MOSFET VDS). |
| PPPM | 600 W (10/1000 µs) - Sustains standard lightning-surge energy without failure when mounted on 5 mm × 5 mm copper pads. |
| RθJA | 120 °C/W - Requires thermal pad layout per datasheet to maintain TJ ≤ 150 °C at 4 W steady-state dissipation. |
| IFSM | 50 A (8.3 ms half-sine) - Withstands brief inrush currents without bond-wire fusing during power-up sequencing. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, unidirectional polarity with cathode indicated by color band. Dimensions: 4.50 mm × 2.79 mm × 2.20 mm (L × W × H); weight 0.064 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction; tied to lower-potential side of protected line (e.g., GND or return path) | Enables unidirectional clamping only on negative transients relative to cathode; not usable for bidirectional protection. |
| Cathode | Current exit point during avalanche; connected to higher-potential side (e.g., VIN, signal line) | Clamps positive transients to VC by shunting surge current to ground through anode; polarity must match DC bias orientation. |
Key Features
| Feature | Design Value |
|---|---|
| Halogen-free, RoHS-compliant construction (M3 suffix) | Meets IEC 61249-2-21 and JEDEC J-STD-203 requirements for environmentally constrained industrial and automotive supply chains. |
| MSL Level 1 rating (260 °C peak reflow) | Supports single-pass lead-free reflow without baking; eliminates moisture-related popcorning during assembly. |
| Low dynamic resistance (RD = 0.229 Ω) | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ESD or relay bounce), improving protection margin. |
| UL 94 V-0 molding compound | Prevents flame propagation in end equipment meeting IEC 62368-1 safety standards for power adapters and industrial controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J16A-E3/5A | Same electrical specs; RoHS-compliant but contains brominated flame retardants (not halogen-free) | Acceptable where halogen-free requirement is waived (e.g., non-EU commercial equipment) | Select E3 if cost sensitivity outweighs halogen-free mandate; M3 required for automotive or EU industrial compliance. |
| SMBJ16A-M3 | Same VWM/VBR/VC, but SMB (DO-214AA) package: 4.57 mm × 3.94 mm footprint, RθJA = 100 °C/W | Higher power handling (600 W same, but better thermal derating due to larger pad area) | Choose SMBJ16A-M3 when board space allows larger package and improved thermal performance is critical for high ambient temperatures. |
Compared with SMA6J16A-M3/5A, the E3 variant offers identical protection performance without halogen-free assurance, while SMBJ16A-M3 provides superior thermal management in space-tolerant designs-neither is pin-compatible due to differing package outlines and pad layouts.

FAQ
What is the maximum clamping voltage of the SMA6J16A-M3/5A under a 10/1000 µs surge?
The SMA6J16A-M3/5A has a maximum clamping voltage (VC) of 25.2 V when subjected to a 10/1000 µs waveform at its rated peak pulse current of 119 A. This value is measured per the conditions specified in the Vishay datasheet (Document Number: 89460, Rev. 09-Jan-2024) and assumes mounting on 5.0 mm × 5.0 mm copper pads. Exceeding this clamping voltage risks damage to downstream components such as MOSFETs or ICs with lower absolute maximum ratings.
Is the SMA6J16A-M3/5A suitable for bidirectional transient protection?
No, the SMA6J16A-M3/5A is a unidirectional TVS diode and is not suitable for bidirectional protection. Its polarity is fixed, with the cathode marked by a color band, and it only clamps positive transients relative to the cathode. For AC or bipolar signal lines, a bidirectional device like SMA6J16CA or a back-to-back diode configuration would be required. Using SMA6J16A-M3/5A on a bidirectional line may result in unintended forward conduction or inadequate protection.
What does the "M3" suffix indicate in SMA6J16A-M3/5A?
Within the SMA6J16A-M3/5A part number, the "M3" suffix denotes halogen-free, RoHS-compliant construction meeting JEDEC J-STD-203 and IEC 61249-2-21 requirements. It also confirms compliance with JESD 201 Class 2 whisker testing and industrial-grade reliability. This distinguishes it from the "E3" variant, which is RoHS-compliant but not halogen-free. The "/5A" indicates packaging in a 13-inch diameter tape-and-reel format containing 7500 units.
How does the thermal resistance of SMA6J16A-M3/5A affect PCB layout?
The SMA6J16A-M3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W, meaning PCB layout directly impacts safe power dissipation. To maintain junction temperature ≤150 °C at 4 W steady-state dissipation (PD), designers must use the minimum recommended 5.0 mm × 5.0 mm copper pads per terminal as specified in the Vishay datasheet. Reducing pad size or omitting thermal vias will increase RθJA, risking thermal runaway during repeated surge events.
Can SMA6J16A-M3/5A be used to protect a 12 V automotive circuit against load dump?
Yes, SMA6J16A-M3/5A is appropriate for protecting 12 V automotive circuits against load-dump transients per ISO 16750-2 Pulse 5a, which specifies up to 35 V for 400 ms. With a 16 V stand-off voltage (VWM) and 25.2 V clamping voltage, it provides sufficient margin below the 35 V limit while handling the required energy. Its 50 A surge rating (8.3 ms) and −55 °C to +150 °C operating range further validate suitability for under-hood automotive applications when properly mounted.
