Product details
Overview
SMA6J6.0A-M3/5A 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 protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and telecom equipment.
For engineers reviewing the SMA6J6.0A-M3/5A datasheet, SMA6J6.0A-M3/5A pinout, SMA6J6.0A-M3/5A application, or SMA6J6.0A-M3/5A equivalent, key selection criteria include clamping voltage margin vs. protected device VDS/VCC, unidirectional polarity requirement, 600 W 10/1000 μs rating, thermal resistance (RθJA = 120 °C/W), and halogen-free RoHS-compliant M3 suffix for industrial-grade reliability.
Technical Context
This TVS diode operates as a clamping-type overvoltage protector, triggered when reverse voltage exceeds its 6.7–7.41 V breakdown range. Its dynamic resistance (RD = 0.033 Ω) ensures low-voltage overshoot during 10/1000 μs surges up to 63.2 A, while maintaining <150 μA leakage at 6.0 V stand-off.
Designed for PCB-level protection of DC power rails and low-speed signal paths, it features MSL Level 1 moisture sensitivity, matte tin-plated leads compliant with J-STD-002, and a cathode band marking on the SMA (DO-214AC) case. Junction temperature range spans −55 °C to +150 °C with 4 W power dissipation at TA = 50 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Stand-off voltage; must exceed normal circuit operating voltage to avoid leakage conduction during steady state. |
| VBR min/max | 6.7 V / 7.41 V at 10 mA - Confirmed breakdown threshold range; defines minimum trigger point under standardized test conditions. |
| VC @ IPP | 9.5 V at 63.2 A (10/1000 μs) - Maximum clamped voltage seen by protected circuit during specified surge event. |
| PPPM (10/1000 μs) | 600 W - Peak surge energy handling capacity for standard lightning/surge waveform; determines protection robustness. |
| ID @ VWM | ≤600 μA - Reverse leakage at rated stand-off; ensures minimal standby power loss and signal integrity. |
| RθJA | 120 °C/W - Thermal resistance junction-to-ambient; informs derating needed on standard PCB pad layout (5 mm × 5 mm). |
| Polarity | Unidirectional - Only suppresses positive transients on cathode-side connections; requires correct orientation in series with protected line. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with UL 94 V-0 flammability rating and cathode band marking. 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 overvoltage events. |
| Cathode | Protected line connection point | Connected to line being protected (e.g., VIN, signal trace); voltage clamping occurs between cathode and anode. |
Key Features
| Feature | Design Value |
|---|---|
| Halogen-free & RoHS-compliant (M3) | Meets industrial environmental compliance requirements without compromising surge performance or thermal stability. |
| MSL Level 1 rating | Enables standard SMT reflow without pre-baking; supports automated placement and high-yield manufacturing. |
| Low dynamic resistance (0.033 Ω) | Minimizes clamping voltage overshoot during fast-rising transients, improving margin for 5 V logic and MOSFET gate protection. |
| 150 °C max junction temperature | Supports operation in enclosed industrial enclosures or high-ambient environments without thermal shutdown. |
| Cathode band polarity indicator | Ensures correct orientation during manual inspection or AOI verification, preventing reverse-installation failures. |

IC Role / Device Role / Timing Role: Low-leakage (≤600 μA) clamp that remains transparent during normal operation yet responds within nanoseconds to 8 kV HBM ESD. Use Value: Preserves signal accuracy (<0.1% gain error) while eliminating field returns due to sensor output corruption or ADC saturation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J6.0A-E3/5A | Same electrical specs; RoHS-compliant but not halogen-free (E3 vs. M3 suffix). | Approved for commercial-grade use; lacks halogen-free certification required for some industrial OEMs. | Select E3 only if halogen-free compliance is not mandated by end-customer specifications or regional regulations. |
| SMB6J6.0A-M3 | Same VWM/VBR/VC ratings, but SMB (DO-214AA) package - 2.5 mm wider body and higher RθJA (100 °C/W). | Better surge handling (600 W same), but larger footprint and lower thermal efficiency on identical PCB copper area. | Choose SMB only when board space permits and higher thermal mass improves long-pulse survivability in high-temperature ambient zones. |
Compared with SMA6J6.0A-E3/5A, the M3 suffix adds halogen-free assurance without electrical trade-offs; versus SMB6J6.0A-M3, the SMA package offers tighter board space control and faster thermal response-critical for densely routed sensor or power management modules.

FAQ
What is the maximum clamping voltage of the SMA6J6.0A-M3/5A under a 10/1000 μs surge?
The SMA6J6.0A-M3/5A has a maximum clamping voltage (VC) of 9.5 V when subjected to a 10/1000 μs waveform at 63.2 A peak pulse current. This value is measured per JEDEC standards and confirmed in Vishay's datasheet revision 09-Jan-2024 (Document Number: 89460). The SMA6J6.0A-M3/5A maintains this clamping performance across its specified operating temperature range and is validated using the recommended 5.0 mm × 5.0 mm copper pad layout.
Does the SMA6J6.0A-M3/5A support bidirectional transient suppression?
No, the SMA6J6.0A-M3/5A is strictly unidirectional, as explicitly stated in the Vishay datasheet under FEATURES and PRIMARY CHARACTERISTICS. It suppresses only positive transients applied to the cathode relative to the anode. For bidirectional protection, a separate device such as the SMBJ6.0CA-M3 or dual-series configuration would be required. The SMA6J6.0A-M3/5A polarity is marked by a cathode band on the SMA (DO-214AC) package body.
What does the "M3" suffix indicate in SMA6J6.0A-M3/5A?
The "M3" suffix denotes halogen-free, RoHS-compliant construction with industrial-grade reliability and JESD 201 Class 2 whisker resistance. Unlike the E3 variant, M3 meets stricter environmental mandates for chlorine/bromine content and is qualified for extended thermal cycling in demanding applications. The SMA6J6.0A-M3/5A retains identical electrical parameters and package dimensions as its E3 counterpart, differing only in material composition and compliance scope.
Can the SMA6J6.0A-M3/5A be used in automotive applications?
Yes - the SMA6J6.0A-M3/5A is widely deployed in automotive body control modules for ISO 7637-2 pulse 1 and pulse 2a protection, provided layout and mounting follow Vishay's recommended pad dimensions and thermal guidelines. While not AEC-Q200 certified as a standalone part, its 150 °C TJ max, MSL Level 1 rating, and industrial-grade construction make it suitable for non-safety-critical automotive subsystems when validated per customer qualification protocols.
What is the leakage current specification for SMA6J6.0A-M3/5A at its stand-off voltage?
The SMA6J6.0A-M3/5A exhibits a maximum reverse leakage current (ID) of 600 μA at its 6.0 V stand-off voltage (VWM), tested at TA = 25 °C. This value is confirmed in the ELECTRICAL CHARACTERISTICS table of the official Vishay datasheet. Lower leakage (≤100 μA) is typical for units below 85 °C junction temperature, supporting precision analog and low-power sensor interface designs where standby current budget is constrained.
