Product details
Overview
SMA6J6.0AHM3/61 from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in SMA (DO-214AC) package, with 6.0 V stand-off voltage (VWM), 6.7–7.41 V breakdown voltage (VBR at 10 mA), and 9.5 V maximum clamping voltage (VC) at 63.2 A peak pulse current (10/1000 µs). It delivers 600 W peak pulse power and is rated for 50 A non-repetitive forward surge current, designed for protecting MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the SMA6J6.0AHM3/61 datasheet, SMA6J6.0AHM3/61 pinout, SMA6J6.0AHM3/61 application, or SMA6J6.0AHM3/61 equivalent, key selection criteria include clamping voltage margin relative to protected device VDS/VDD, thermal resistance (RθJA = 120 °C/W), unidirectional polarity requirement, and MSL Level 1 compliance for lead-free reflow.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches to divert surge current away from downstream components. Its dynamic resistance (RD = 0.033 Ω) and low clamping ratio (VC/VWM ≈ 1.58) ensure tight overvoltage control during 10/1000 µs transients.
Designed for PCB-level protection of DC rails and signal lines, it features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets UL 94 V-0 flammability rating. The SMA package supports automated placement and achieves thermal performance via 5.0 mm × 5.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before significant leakage; sets upper limit for protected circuit's nominal rail. |
| VBR (min/max) | 6.7 V / 7.41 V at 10 mA - Breakdown onset range; defines minimum overvoltage threshold for clamping activation. |
| VC @ IPP | 9.5 V at 63.2 A (10/1000 µs) - Maximum clamped voltage seen by protected device during standard surge event. |
| PPPM (10/1000 µs) | 600 W - Peak transient energy handling capacity under standardized long-duration surge waveform. |
| ID @ VWM | 600 µA max - Reverse leakage current at stand-off voltage; low value minimizes standby power loss. |
| RθJA | 120 °C/W - Junction-to-ambient thermal resistance; determines temperature rise under 4 W steady-state dissipation. |
| Polarity | Unidirectional - Cathode-banded device; protects against positive transients only on anode-to-cathode orientation. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with cathode band marking. Dimensions: 4.50 mm × 2.79 mm × 2.20 mm (L × W × H); weight 0.064 g.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J6.0A-E3/61 | RoHS-compliant but contains brominated flame retardants; same VWM, VBR, VC, and package. | Approved for industrial-grade use where halogen content is unrestricted. | Select when halogen-free requirement is not mandated and cost optimization is prioritized. |
| SMCJ6.0A-M3 | Higher PPPM (1500 W), larger SMC (DO-214AB) package, RθJA = 40 °C/W - lower thermal impedance but requires more board area. | Better suited for higher-energy surges or thermally constrained environments where SMA footprint is insufficient. | Choose when surge energy exceeds 600 W or junction temperature rise must stay below 50 °C under sustained 4 W dissipation. |
Compared with SMA6J6.0AHM3/61, SMA6J6.0A-E3/61 offers identical electrical specs but lacks halogen-free certification, while SMCJ6.0A-M3 trades compactness for higher surge robustness and improved thermal performance - enabling longer surge endurance in high-power industrial controls.

FAQ
What is the clamping voltage of the SMA6J6.0AHM3/61 under a 10/1000 µs surge?
The SMA6J6.0AHM3/61 has a maximum clamping voltage (VC) of 9.5 V at 63.2 A peak pulse current under the 10/1000 µs waveform. This value is measured per the test conditions specified in the Vishay datasheet (Document Number: 89460), using the recommended PCB pad layout and at TA = 25 °C. The SMA6J6.0AHM3/61 maintains this clamping performance across its qualified operating temperature range.
Is the SMA6J6.0AHM3/61 suitable for lead-free reflow soldering?
Yes, the SMA6J6.0AHM3/61 is rated for MSL Level 1 per J-STD-020 and supports a maximum peak reflow temperature of 260 °C, making it fully compatible with standard lead-free soldering processes. Its matte tin-plated terminals meet J-STD-002 and JESD 22-B102 solderability requirements, and the M3 suffix confirms halogen-free, RoHS-compliant construction suitable for high-reliability industrial assembly. The SMA6J6.0AHM3/61 does not require pre-baking prior to reflow.
How does the SMA6J6.0AHM3/61 differ from the SMA6J6.0A-E3/61?
The SMA6J6.0AHM3/61 and SMA6J6.0A-E3/61 share identical electrical specifications - including VWM = 6.0 V, VBR = 6.7–7.41 V, VC = 9.5 V, and PPPM = 600 W - and both use the SMA (DO-214AC) package. The key distinction is environmental compliance: the "M3" suffix denotes halogen-free molding compound, whereas "E3" indicates RoHS-compliant but brominated flame retardant material. Both are rated for industrial temperature range (–55 °C to +150 °C) and MSL Level 1.
What is the maximum leakage current of the SMA6J6.0AHM3/61 at its stand-off voltage?
The SMA6J6.0AHM3/61 exhibits a maximum reverse leakage current (ID) of 600 µA at its stand-off voltage (VWM = 6.0 V), measured at TA = 25 °C. This low leakage ensures minimal power loss in always-on protection circuits and avoids interference with high-impedance monitoring nodes. The leakage remains within specification across the full operating temperature range, supporting reliable operation in battery-powered and low-quiescent-current designs.
Can the SMA6J6.0AHM3/61 be used in bidirectional protection circuits?
No, the SMA6J6.0AHM3/61 is a unidirectional TVS diode and is not suitable for bidirectional protection. Its cathode band marking and internal structure provide clamping only for positive transients applied anode-to-cathode. For AC or bipolar transient suppression, a dedicated bidirectional device such as the SMBJ6.0CA or a back-to-back unidirectional pair would be required. Using the SMA6J6.0AHM3/61 in reverse bias beyond its VWM risks permanent damage due to lack of reverse conduction capability.
