Product details
Overview
SMA6J6.5A-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 6.5 V stand-off voltage (VWM), 7.2–7.96 V breakdown voltage (VBR at 10 mA), 10.2 V maximum clamping voltage at 58.8 A (10/1000 μs), 600 W peak pulse power, and operates from –55 °C to +150 °C junction temperature - used to protect MOSFETs and ICs in industrial power supplies.
For engineers reviewing the SMA6J6.5A-M3/61 datasheet, SMA6J6.5A-M3/61 pinout, SMA6J6.5A-M3/61 application, or SMA6J6.5A-M3/61 equivalent, key selection criteria include clamping voltage at rated surge current, unidirectional polarity compatibility, SMA package 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 it presents <100 μA leakage at 6.5 V; during transient events, it avalanches at ≥7.2 V and clamps to ≤10.2 V at 58.8 A (10/1000 μs). Its dynamic resistance is 0.038 Ω, enabling fast response to ESD and inductive switching spikes.
Designed for PCB mounting with 5.0 mm × 5.0 mm copper pads per terminal, it meets MSL level 1 per J-STD-020, supports 260 °C lead-free reflow, and uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 - ensuring robust solder joint reliability in automated SMT assembly.

IC Role / Device Role / Timing Role: Parallel-connected TVS across motor terminals, conducting only during voltage reversal exceeding VBR. Use Value: 600 W PPPM rating handles repetitive 10/1000 μs pulses without degradation; RθJA = 120 °C/W allows direct PCB mounting without heatsink. |
Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loop) of pressure sensors in factory automation systems. IC Role / Device Role / Timing Role: Low-capacitance unidirectional clamp on signal line to GND, minimizing signal distortion at DC–1 kHz bandwidth. Use Value: 100 μA max ID at VWM avoids loading precision current sources; 10.2 V clamping prevents op-amp rail-to-rail saturation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J6.5A-E3/61 | Same electrical specs; RoHS-compliant but not halogen-free (E3 vs. M3) | Approved for consumer electronics where halogen-free requirement is absent | Select E3 for cost-sensitive non-automotive designs; M3 required for automotive or EU industrial compliance |
| SMBJ6.5A-M3 | Higher 600 W PPPM rating retained, but SMB package (DO-214AA) offers 15% larger pad area and lower RθJA (90 °C/W) | Better thermal performance in high-duty-cycle surge environments; requires larger PCB footprint | Choose SMBJ6.5A-M3 when board layout permits larger package and thermal derating is critical |
Compared with SMA6J6.5A-M3/61, the E3 variant trades halogen-free status for slightly lower cost without electrical change, while SMBJ6.5A-M3 improves thermal dissipation at the expense of PCB area - both require review of mechanical fit and compliance documentation before substitution.

FAQ
What is the maximum clamping voltage of the SMA6J6.5A-M3/61 under a 10/1000 µs surge?
The SMA6J6.5A-M3/61 has a maximum clamping voltage (VC) of 10.2 V when subjected to a 10/1000 µs waveform at its rated peak pulse current of 58.8 A. This value is measured per the test conditions specified in the Vishay datasheet (Document Number: 89460), with the device mounted on a PCB using 5.0 mm × 5.0 mm copper pads per terminal. The SMA6J6.5A-M3/61 achieves this clamping performance while maintaining low dynamic resistance (0.038 Ω), ensuring predictable voltage limiting during transient events.
Does the SMA6J6.5A-M3/61 support lead-free reflow soldering?
Yes, the SMA6J6.5A-M3/61 is qualified for lead-free reflow soldering with a maximum peak temperature of 260 °C, meeting J-STD-020 MSL level 1 requirements. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 for solderability, and the M3 suffix confirms halogen-free, RoHS-compliant construction. The SMA6J6.5A-M3/61 is designed for fully automated SMT placement and reflow processes without degradation of surge performance or reliability.
How does the SMA6J6.5A-M3/61 differ from the SMA6J6.5A-E3/61?
The SMA6J6.5A-M3/61 and SMA6J6.5A-E3/61 share identical electrical specifications, including VWM = 6.5 V, VBR = 7.2–7.96 V, and VC = 10.2 V. The distinction lies in material composition: M3 denotes halogen-free and RoHS-compliant construction, whereas E3 is RoHS-compliant but contains halogens. Both meet JESD 201 class 2 whisker resistance. The SMA6J6.5A-M3/61 is specified for automotive and industrial applications requiring halogen-free compliance per IPC-1752A.
What is the leakage current specification for the SMA6J6.5A-M3/61 at its stand-off voltage?
The SMA6J6.5A-M3/61 exhibits a maximum reverse leakage current (ID) of 100 μA when biased at its stand-off voltage (VWM) of 6.5 V, measured at TA = 25 °C. This low leakage ensures minimal power loss in always-on circuits and avoids loading sensitive analog or low-current digital inputs. The SMA6J6.5A-M3/61 maintains this specification across its full operating temperature range (–55 °C to +150 °C), supporting reliable performance in thermally demanding environments.
Can the SMA6J6.5A-M3/61 be used in bidirectional protection configurations?
No, the SMA6J6.5A-M3/61 is a unidirectional TVS diode and is not suitable for bidirectional transient suppression. Its internal structure supports conduction only from cathode to anode during overvoltage events on the cathode side. For AC or dual-polarity signal lines, a dedicated bidirectional device such as SMBJ6.5CA-M3 or a back-to-back diode arrangement is required. The SMA6J6.5A-M3/61 datasheet explicitly states "Available in unidirectional polarity only" - confirming that bidirectional operation is not supported.
