Product details
Overview
SMA6J5.0A-M3/5A from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in SMA (DO-214AC) package, rated for 5.0 V stand-off voltage, 6.4–7.07 V breakdown at 10 mA, 9.1 V max clamping voltage at 65.9 A (10/1000 µs), and 600 W peak pulse power. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and telecom equipment.
For engineers reviewing the SMA6J5.0A-M3/5A datasheet, SMA6J5.0A-M3/5A pinout, SMA6J5.0A-M3/5A application, or SMA6J5.0A-M3/5A equivalent, key selection criteria include clamping voltage at rated IPP, unidirectional polarity, MSL level 1 compliance, halogen-free RoHS status (M3 suffix), and thermal resistance of 120 °C/W junction-to-ambient.
Technical Context
This device operates as a silicon avalanche diode designed to clamp transient overvoltages before they damage downstream circuitry. Its dynamic resistance of 0.031 Ω and low clamping ratio (VC/VBR ≈ 1.43) ensure rapid response and minimal let-through energy during 10/1000 µs surges up to 65.9 A.
Thermal performance is defined by RθJA = 120 °C/W and RθJL = 25 °C/W, with maximum junction temperature of +150 °C and derating above TA = 25 °C per Fig. 2. The cathode band denotes polarity, and terminals are matte tin-plated for J-STD-002 solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum reverse voltage before significant leakage; sets operating margin below breakdown. |
| VBR min/max | 6.4 V / 7.07 V at IT = 10 mA - Confirms reliable avalanche initiation within spec; ensures consistent turn-on across production lot. |
| VC at IPP | 9.1 V at 65.9 A (10/1000 µs) - Clamping voltage under standard surge; defines worst-case stress on protected IC input. |
| PPPM (10×1000 µs) | 600 W - Surge energy handling capacity; determines survivability of common inductive load-switching events. |
| ID at VWM | 150 µA max - Low leakage preserves signal integrity and battery life in always-on sensor interfaces. |
| TJ max | +150 °C - Enables operation in high-temperature industrial enclosures without derating penalties beyond datasheet curves. |
| Package | SMA (DO-214AC) - Standardized SMT footprint compatible with automated placement; 5.0 mm × 5.0 mm copper pad requirement for thermal management. |
Pinout & Package
Two-terminal unidirectional TVS diode in SMA (DO-214AC) package. Cathode denoted by color band; anode is opposite end. Matte tin-plated leads meet J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current return path | Connected to ground or low-impedance reference; completes clamping loop during surge event. |
| Cathode | Transient voltage sensing node | Connected to protected line (e.g., I/O, power rail); avalanche conduction begins here when V > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Clamping voltage ratio VC/VBR | 1.43 - Tight ratio minimizes overvoltage exposure while maintaining margin against false triggering. |
| Dynamic resistance RD | 0.031 Ω - Low impedance limits voltage overshoot during fast-rising transients (e.g., ESD, relay bounce). |
| MSL Level 1 rating | 260 °C peak reflow - Supports standard lead-free assembly without pre-baking or special handling. |
| Halogen-free & RoHS-compliant (M3) | Meets IPC-4101D/21 and JEDEC J-STD-20E - Required for export to EU, China, and other regulated markets. |
| Junction-to-ambient thermal resistance | 120 °C/W - Enables 4 W continuous dissipation at TA = 50 °C with standard PCB layout (5 mm × 5 mm pads). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J5.0A-E3/5A | Same electrical specs; RoHS-compliant but not halogen-free (E3 vs. M3). | Acceptable where halogen-free material is not mandated (e.g., non-EU commercial products). | Select E3 for cost-sensitive designs with standard RoHS compliance; choose M3 when IPC-4101D/21 or JEDEC J-STD-20E is required. |
| SMCJ5.0A-M3 | Higher PPPM (1500 W @ 10/1000 µs); larger SMC (DO-214AB) package; same VWM/VBR/VC. | Better suited for higher-energy surges (e.g., AC mains coupling, heavy industrial loads); requires larger PCB area. | Choose SMCJ5.0A-M3 when surge threat exceeds 600 W; retain SMA6J5.0A-M3/5A for space-constrained 5 V rail protection. |
Compared with SMA6J5.0A-E3/5A, the M3 suffix adds halogen-free compliance without electrical trade-offs; versus SMCJ5.0A-M3, it trades 2.5× surge capacity for 40 % smaller footprint and identical clamping behavior-ideal for dense sensor or telecom interface layouts.

FAQ
What is the clamping voltage of the SMA6J5.0A-M3/5A at its rated peak pulse current?
The SMA6J5.0A-M3/5A has a maximum clamping voltage (VC) of 9.1 V at 65.9 A peak pulse current with a 10/1000 µs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The SMA6J5.0A-M3/5A maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C) with appropriate derating.
Is the SMA6J5.0A-M3/5A suitable for bidirectional transient protection?
No, the SMA6J5.0A-M3/5A is unidirectional only, as confirmed in the Vishay datasheet features section. It conducts only during reverse-biased overvoltage events and blocks forward current beyond VF ≈ 3.5 V at 25 A. For bidirectional protection, a pair of SMA6J5.0A-M3/5A devices in series opposition or a dedicated bidirectional TVS such as SMBJ5.0CA would be required. The SMA6J5.0A-M3/5A must be oriented with cathode toward the protected line.
What does the "M3" suffix indicate in SMA6J5.0A-M3/5A?
The "M3" suffix in SMA6J5.0A-M3/5A specifies halogen-free, RoHS-compliant construction meeting IPC-4101D/21 and JEDEC J-STD-20E requirements. It also passes JESD 201 Class 2 whisker testing. This differs from the "E3" variant, which is RoHS-compliant but contains brominated flame retardants. Both share identical electrical characteristics and SMA package dimensions, making M3 the preferred choice for environmentally regulated markets.
Can the SMA6J5.0A-M3/5A handle 8/20 µs lightning surges?
Yes-the SMA6J5.0A-M3/5A is rated for 4000 W peak pulse power with an 8/20 µs waveform, corresponding to a peak current of 298 A. This rating supports IEC 61000-4-5 Level 4 (4 kV/2 kA) surge immunity when properly mounted on 5.0 mm × 5.0 mm copper pads. Its low dynamic resistance (0.031 Ω) ensures effective clamping even during fast-rising transients typical of lightning-induced surges.
What is the thermal resistance and maximum power dissipation of the SMA6J5.0A-M3/5A at 50 °C ambient?
The SMA6J5.0A-M3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W and a maximum power dissipation (PD) of 4.0 W at TA = 50 °C. This rating assumes mounting on PCB with 5.0 mm × 5.0 mm copper pads per terminal, per datasheet Note (2). Derating is required above 50 °C ambient per Figure 2, reaching zero dissipation at TJ = 150 °C. The SMA6J5.0A-M3/5A remains within safe operating limits under continuous 4 W load at 50 °C with proper layout.
