Product details
Overview
SMA5J6.0A-M3/5A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR at 10 mA), 500 W peak pulse power (10/1000 µs), 48.5 A peak pulse current (IPPM), and clamps to ≤10.3 V at rated surge. It is widely deployed in automotive ECUs and industrial sensor interfaces where fast response and low clamping are critical.
For engineers reviewing the SMA5J6.0A-M3/5A datasheet, SMA5J6.0A-M3/5A pinout, SMA5J6.0A-M3/5A application, or SMA5J6.0A-M3/5A equivalent, key selection criteria include verified unidirectional polarity, halogen-free RoHS compliance (M3 suffix), 150 °C max junction temperature, and compatibility with automated SMT placement on standard 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device triggered by reverse-biased avalanche breakdown above its VWM. Its glass-passivated junction ensures stable leakage (<800 µA at 6.0 V) and repeatable VBR tolerance (±5%). The 10/1000 µs surge rating reflects standardized lightning/surge immunity testing per ANSI/IEEE C62.35.
Thermal performance is defined by RθJA = 80 °C/W (on recommended pad layout) and RθJL = 25 °C/W, enabling reliable operation up to 150 °C junction temperature. The M3 suffix confirms halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance and J-STD-020 MSL Level 1 reflow profile (260 °C peak).
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 line voltage. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed avalanche initiation range; ensures predictable turn-on across production lot. |
| VC @ IPPM | ≤10.3 V at 48.5 A - Clamping voltage under 500 W 10/1000 µs surge; defines worst-case overvoltage seen by downstream IC. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J6.0A-E3/5A | Same electrical specs, but RoHS-compliant commercial grade (E3) without halogen-free certification; uses standard SnPb-free plating. | Approved for non-automotive industrial and consumer use; not qualified for AEC-Q101 or halogen-free mandates. | Select SMA5J6.0A-E3/5A when halogen-free requirement is absent and cost sensitivity outweighs green compliance needs. |
| SMA5J6.0AHE3_A/5A | AEC-Q101 qualified, RoHS-compliant, same VWM/VBR/PPPM, but higher screening cost and longer lead time; marked with revision code "A". | Required for automotive safety-critical modules (e.g., airbag controllers, EPS); includes extended temperature and lifetime testing. | Choose SMA5J6.0AHE3_A/5A only when automotive qualification and traceability (lot-level test reports) are contractually mandated. |
Compared with SMA5J6.0A-E3/5A, the SMA5J6.0A-M3/5A adds halogen-free compliance without sacrificing surge rating or thermal performance, while SMA5J6.0AHE3_A/5A trades cost and availability for automotive-grade validation-making SMA5J6.0A-M3/5A the optimal balance for industrial and Tier-2 automotive designs.

FAQ
What is the maximum clamping voltage of the SMA5J6.0A-M3/5A under full-rated surge conditions?
The SMA5J6.0A-M3/5A clamps to a maximum of 10.3 V when subjected to its rated 48.5 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured at TA = 25 °C on the recommended 5.0 mm × 5.0 mm copper pad layout and represents the worst-case overvoltage imposed on protected circuitry during surge events. The SMA5J6.0A-M3/5A maintains this clamping performance across its full operating temperature range.
Does the SMA5J6.0A-M3/5A meet automotive qualification standards?
The SMA5J6.0A-M3/5A is halogen-free and RoHS-compliant but is not AEC-Q101 qualified. For automotive applications requiring formal qualification, Vishay offers the SMA5J6.0AHE3_A/5A variant, which carries full AEC-Q101 certification. The SMA5J6.0A-M3/5A remains suitable for non-safety-critical automotive subsystems (e.g., infotainment, lighting control) where halogen-free compliance is required but formal qualification is not mandated.
How does the M3 suffix differ from the E3 suffix in the SMA5J6.0A-M3/5A part number?
The M3 suffix in SMA5J6.0A-M3/5A denotes halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance, whereas the E3 suffix (e.g., SMA5J6.0A-E3/5A) indicates RoHS-compliance without halogen-free certification. Both share identical electrical specifications and package dimensions, but only M3 satisfies strict environmental mandates in EU automotive and industrial markets where brominated flame retardants are prohibited.
What is the thermal resistance of the SMA5J6.0A-M3/5A, and how does it affect PCB layout?
The SMA5J6.0A-M3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To achieve this rating, PCB layout must replicate the specified pad size and copper area; reducing pad size increases RθJA, raising junction temperature under surge and potentially degrading long-term reliability. The SMA5J6.0A-M3/5A also exhibits RθJL = 25 °C/W to the lead, supporting thermal transfer through solder joints.
Can the SMA5J6.0A-M3/5A be used in bidirectional protection circuits?
No-the SMA5J6.0A-M3/5A is a unidirectional TVS diode, identified by its cathode band marking. Bidirectional operation requires the CA-suffixed variant (e.g., SMA5J6.0CA). Using SMA5J6.0A-M3/5A in a bidirectional configuration would result in forward conduction during negative transients, causing excessive current flow and device failure. Always match polarity: SMA5J6.0A-M3/5A for DC rails with defined ground reference; SMA5J6.0CA for AC-coupled or floating signal lines.
