Overview
SMA6J5.0AHM3/61 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 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR at 10 mA), 9.1 V maximum clamping voltage at 65.9 A (10/1000 μs), 600 W peak pulse power rating, and operates from –55 °C to +150 °C. It protects MOSFETs and ICs in industrial power supplies.
For engineers reviewing the SMA6J5.0AHM3/61 datasheet, SMA6J5.0AHM3/61 pinout, SMA6J5.0AHM3/61 application, or SMA6J5.0AHM3/61 equivalent, key selection criteria include clamping voltage at rated surge current, unidirectional polarity compatibility, thermal resistance (RθJA = 120 °C/W), JEDEC MSL Level 1 compliance, and halogen-free RoHS-compliant construction per suffix M3.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device triggered above its reverse breakdown threshold. Its dynamic resistance (RD = 0.031 Ω) enables low-voltage overshoot during 10/1000 μs surges up to 65.9 A, while maintaining 5.0 V stand-off capability with ≤150 μA leakage at rated VWM.
Designed for PCB-level transient suppression, it uses a planar junction structure in an SMA package with matte tin-plated leads solderable per J-STD-002. The device meets JESD201 Class 2 whisker testing and UL 94 V-0 flammability requirements, supporting automated placement without reflow derating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J5.0A-E3/61 | Same electrical specs; RoHS-compliant but contains brominated flame retardants (non-halogen-free). | Acceptable where halogen-free requirement is not mandated by end-equipment standards (e.g., non-automotive consumer). | Select when cost sensitivity outweighs halogen-free compliance; identical footprint and thermal behavior. |
| SMCJ5.0A-M3 | Higher 1500 W PPPM (10/1000 μs), DO-214AB (SMC) package (7.11 mm × 6.22 mm), RθJA ≈ 35 °C/W. | Suitable for higher-energy surges but requires larger PCB area and different pad layout; better for primary-stage protection. | Choose for systems requiring >600 W surge handling; not drop-in due to larger footprint and different thermal interface. |
Compared with SMA6J5.0AHM3/61, the E3 variant trades halogen-free status for lower cost without electrical change, while SMCJ5.0A-M3 delivers higher surge capacity at the expense of board space and thermal design complexity-neither is pin-compatible, but both serve overlapping protection roles in tiered surge architectures.

FAQ
What is the maximum clamping voltage of the SMA6J5.0AHM3/61 under a 10/1000 μs surge?
The SMA6J5.0AHM3/61 exhibits a maximum clamping voltage (VC) of 9.1 V when subjected to a 10/1000 μs surge current of 65.9 A. This value is measured per the conditions specified in the Vishay datasheet (Document Number: 89460), with the device mounted on 5.0 mm × 5.0 mm copper pads. It reflects the actual voltage imposed on protected circuitry during standardized lightning-surge testing.
Is SMA6J5.0AHM3/61 compatible with lead-free reflow soldering processes?
Yes, SMA6J5.0AHM3/61 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 terminals comply with J-STD-002 and JESD 22-B102 solderability standards, and the M3 suffix confirms halogen-free, RoHS-compliant construction suitable for modern assembly lines.
Does SMA6J5.0AHM3/61 support bidirectional transient suppression?
No, SMA6J5.0AHM3/61 is a unidirectional TVS diode, intended only for DC-biased or single-polarity signal/power lines. Its electrical characteristics-including breakdown voltage, clamping behavior, and leakage-are defined exclusively for reverse-bias operation. For AC or bidirectional protection, a dedicated bidirectional TVS such as SMA6J5.0CA must be selected instead of SMA6J5.0AHM3/61.
What is the thermal resistance junction-to-ambient (RθJA) for SMA6J5.0AHM3/61?
The typical thermal resistance junction-to-ambient (RθJA) for SMA6J5.0AHM3/61 is 120 °C/W, measured with the device mounted on PCB copper pads of 5.0 mm × 5.0 mm per terminal. This value assumes still air conditions and informs thermal design margins when estimating junction temperature rise under sustained power dissipation or repetitive surge duty cycles.
How does the M3 suffix in SMA6J5.0AHM3/61 affect its compliance and reliability?
The M3 suffix in SMA6J5.0AHM3/61 indicates halogen-free, RoHS-compliant construction that also passes JESD201 Class 2 whisker testing. Unlike the E3 variant, M3 eliminates brominated flame retardants while maintaining UL 94 V-0 flammability rating-critical for automotive and industrial applications where material outgassing and long-term interconnect reliability are strictly controlled.
