Product details
Overview
SMA6J5.0A-M3/61 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, with 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR at 10 mA), 9.1 V maximum clamping voltage (VC at 65.9 A), 600 W peak pulse power (10/1000 µs), and 50 A peak forward surge current. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and telecom equipment.
For engineers reviewing the SMA6J5.0A-M3/61 datasheet, SMA6J5.0A-M3/61 pinout, SMA6J5.0A-M3/61 application, or SMA6J5.0A-M3/61 equivalent, key selection criteria include clamping performance at 65.9 A IPPM, thermal resistance (RθJA = 120 °C/W), unidirectional polarity, halogen-free RoHS compliance (M3 suffix), and compatibility with automated SMT placement on standard PCB pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents <150 µA leakage at 5.0 V, then avalanches sharply above 6.4 V to clamp transients within 9.1 V at 65.9 A (10/1000 µs). Its dynamic resistance is 0.031 Ω, enabling fast response to sub-microsecond surges.
Designed for surface-mount reliability, it meets MSL Level 1 per J-STD-020, withstands 260 °C reflow peak, and uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. The SMA package provides 120 °C/W junction-to-ambient thermal resistance with 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum reverse working voltage before conduction begins; defines safe operating margin for 5 V rail protection. |
| VBR (min/max) | 6.4 V / 7.07 V at 10 mA - Breakdown onset range; ensures reliable triggering above system nominal voltage. |
| VC at IPPM | 9.1 V at 65.9 A (10/1000 µs) - Clamping voltage during worst-case transient; limits stress on downstream ICs. |
| PPPM (10/1000 µs) | 600 W - Peak pulse power handling; determines survivability of common inductive load-switching events. |
| ID at VWM | ≤150 µA - Reverse leakage at rated stand-off; minimizes standby power loss in battery-powered sensors. |
| RθJA | 120 °C/W - Junction-to-ambient thermal resistance with recommended pad layout; guides PCB copper area design. |
| Polarity | Unidirectional - Cathode marked by band; suitable only for DC-biased or positive-transient protection. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, halogen-free, RoHS-compliant, industrial grade (M3 suffix), cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry during forward conduction or transient clamping | Connected to protected line (e.g., signal trace or power rail anode side); must be routed with low-inductance path. |
| Cathode | Current exit during clamping; marked by band | Connected to ground or lower-potential reference; determines unidirectional clamping direction. |
Key Features
| Feature | Design Value |
|---|---|
| Clamping ratio VC/VBR | 1.43 (9.1 V / 6.4 V) - Low ratio ensures minimal overvoltage exposure to protected ICs during surge events. |
| Dynamic resistance RD | 0.031 Ω - Enables tight clamping with minimal voltage rise under high di/dt transients. |
| MSL Level 1 rating | Compatible with standard SMT reflow profiles up to 260 °C peak - eliminates moisture sensitivity handling requirements. |
| Halogen-free construction | M3 suffix confirms IEC 61249-2-21 compliance - meets environmental mandates for industrial and telecom equipment. |
| Junction temperature range | -55 °C to +150 °C - Supports operation in extended-temperature environments such as automotive under-hood or outdoor base stations. |

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-E3/61 | Same electrical specs; RoHS-compliant but not halogen-free (E3 vs. M3) | Acceptable where halogen-free mandate does not apply (e.g., non-EU industrial OEMs) | Select E3 for cost-sensitive designs without halogen restrictions; verify regional compliance requirements. |
| SMBJ5.0A-M3 | Higher 600 W PPPM (10/1000 µs), same VWM/VBR/VC, but SMB (DO-214AA) package - 2.5 mm wider body, higher RθJA (100 °C/W) | Better power handling but requires larger PCB footprint; less thermally efficient on same pad size | Choose SMBJ5.0A-M3 only when 600 W rating must be sustained at elevated ambient temperatures (>70 °C). |
Compared with SMA6J5.0A-M3/61, the E3 variant offers identical protection performance without halogen-free certification, while SMBJ5.0A-M3 trades smaller footprint for reduced thermal efficiency and larger board area - making SMA6J5.0A-M3/61 optimal for space-constrained, thermally managed 5 V rail protection.

FAQ
What is the clamping voltage of SMA6J5.0A-M3/61 at its rated peak pulse current?
The SMA6J5.0A-M3/61 has a maximum clamping voltage (VC) of 9.1 V at 65.9 A peak pulse current (IPPM) under the 10/1000 µs waveform condition. This value is measured per the datasheet's Electrical Characteristics table and reflects actual device behavior when suppressing typical inductive transients. The SMA6J5.0A-M3/61 maintains this clamping performance across its operating temperature range and is validated with the specified 5.0 mm × 5.0 mm copper pad layout.
Is SMA6J5.0A-M3/61 suitable for bidirectional transient protection?
No, SMA6J5.0A-M3/61 is unidirectional only, as confirmed in the Features section and Electrical Characteristics table. It conducts only during positive transients relative to its cathode and cannot suppress negative-going surges on AC or bipolar signal lines. For bidirectional protection, a different device such as the SMBJ5.0CA-M3 or dedicated bidirectional TVS array must be used. The SMA6J5.0A-M3/61 polarity is marked by a cathode band and must be oriented accordingly in-circuit.
What does the "M3" suffix indicate for SMA6J5.0A-M3/61?
The "M3" suffix on SMA6J5.0A-M3/61 denotes halogen-free, RoHS-compliant, industrial-grade construction per Vishay's material categorization standards. It satisfies IEC 61249-2-21 and includes matte tin-plated leads qualified to JESD 201 Class 2 whisker testing. Unlike the E3 variant, M3 ensures full compliance with EU RoHS Annex II halogen restrictions and is required for products targeting environmentally regulated markets such as EU industrial equipment and telecom infrastructure.
How does the thermal resistance of SMA6J5.0A-M3/61 affect PCB layout?
The SMA6J5.0A-M3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal, as specified in the Thermal Characteristics table. To maintain safe junction temperature under 4 W continuous dissipation or repetitive surges, designers must allocate adequate copper area and avoid thermal isolation. Reducing pad size increases RθJA significantly, risking thermal runaway during sustained overload conditions. The SMA6J5.0A-M3/61 thermal performance is validated only with this minimum pad layout.
Can SMA6J5.0A-M3/61 replace SMAJ5.0A in existing designs?
No, SMA6J5.0A-M3/61 is not a direct replacement for SMAJ5.0A due to differences in peak pulse power rating: SMA6J5.0A-M3/61 is rated for 600 W (10/1000 µs), whereas SMAJ5.0A delivers 400 W under the same waveform. Although both share the SMA package and similar VWM/VBR, the SMA6J5.0A-M3/61 offers 50 % higher surge energy handling. Substituting without validation may overstress downstream components if the original design relied on SMAJ5.0A's lower clamping energy profile. Always verify transient immunity margins before interchanging.
