Product details
Overview
SMA6J5.0AHM3/5A from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in SMA (DO-214AC) package, with 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR), and 9.1 V maximum clamping voltage (VC) at 65.9 A peak pulse current (IPP) under 10/1000 μs waveform. It delivers 600 W peak pulse power and protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and telecom equipment.
For engineers reviewing the SMA6J5.0AHM3/5A datasheet, SMA6J5.0AHM3/5A pinout, SMA6J5.0AHM3/5A application, or SMA6J5.0AHM3/5A equivalent, key selection criteria include clamping performance at 65.9 A IPP, unidirectional polarity, 120 °C/W junction-to-ambient thermal resistance, RoHS-compliant halogen-free construction (M3 suffix), and compatibility with automated SMT placement on standard PCB pads.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 6.4–7.07 V breakdown range. Its dynamic resistance (RD = 0.031 Ω) enables low-voltage clamping at high surge currents, while the 120 °C/W thermal resistance requires careful PCB copper pad design per JEDEC guidelines for sustained 4 W power dissipation at TA = 50 °C.
It meets MSL level 1 per J-STD-020, supports 260 °C lead-free reflow, and features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. The cathode band marking and DO-214AC mechanical outline ensure unambiguous orientation during assembly.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J5.0A-E3/5A | RoHS-compliant, non-halogen-free; same electrical specs and SMA package | Preferred where halogen content is unrestricted and cost sensitivity is higher | Select when compliance with IPC-4101D halogen-free requirements is not mandated |
| SMCJ5.0A-M3 | Higher 1500 W PPPM (10/1000 μs); larger SMC (DO-214AB) package; 9.2 V VC @ 163 A | Used where surge energy exceeds 600 W or board space allows larger footprint | Choose only if system-level surge testing requires >600 W margin or thermal mass permits larger case |
Compared with SMA6J5.0AHM3/5A, SMA6J5.0A-E3/5A offers identical protection performance with lower material compliance constraints, while SMCJ5.0A-M3 provides higher surge capacity at the cost of increased board area and thermal inertia-neither is pin-compatible due to differing package outlines.

FAQ
What is the clamping voltage of SMA6J5.0AHM3/5A at its rated peak pulse current?
The SMA6J5.0AHM3/5A has a maximum clamping voltage (VC) of 9.1 V at 65.9 A peak pulse current (IPP) under the 10/1000 μs waveform. This value is measured per the manufacturer's test conditions and defines the upper voltage limit imposed on protected circuits during standardized surge events. The SMA6J5.0AHM3/5A maintains this clamping performance consistently across its qualified operating temperature range.
Does SMA6J5.0AHM3/5A support lead-free reflow soldering?
Yes, SMA6J5.0AHM3/5A meets J-STD-020 MSL level 1 and is rated for lead-free reflow with a maximum peak temperature of 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 solderability standards, ensuring reliable wetting and joint formation during standard SMT processes. The SMA6J5.0AHM3/5A packaging and termination are fully qualified for high-volume automated assembly.
How does the M3 suffix affect the material composition of SMA6J5.0AHM3/5A?
The M3 suffix on SMA6J5.0AHM3/5A indicates halogen-free, RoHS-compliant construction meeting IPC-4101D requirements, with no brominated flame retardants or chlorine-based additives in the molding compound. This differs from the E3 variant, which is RoHS-compliant but not halogen-free. The SMA6J5.0AHM3/5A maintains identical electrical and thermal specifications regardless of suffix.
What is the maximum allowable leakage current for SMA6J5.0AHM3/5A at its stand-off voltage?
The SMA6J5.0AHM3/5A exhibits a maximum reverse leakage current (ID) of 150 μA at its 5.0 V stand-off voltage (VWM) and TA = 25 °C. This low leakage ensures minimal impact on power-sensitive applications such as battery-backed sensor nodes or always-on microcontroller domains. The SMA6J5.0AHM3/5A leakage remains within specification across its full operating temperature range.
Can SMA6J5.0AHM3/5A be used in bidirectional configurations?
No, SMA6J5.0AHM3/5A is specified for unidirectional polarity only, as confirmed in the Vishay datasheet. It contains a single PN junction optimized for reverse-biased transient suppression and lacks symmetrical breakdown characteristics required for bidirectional operation. For bidirectional protection, discrete back-to-back configurations or dedicated bidirectional TVS devices such as SMBJ5.0CA must be selected instead of SMA6J5.0AHM3/5A.
