Product details
Overview
SMA6F5.0A-M3/6B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SlimSMA (DO-221AC) package, designed for clamping voltage transients on 5.0 V signal or power lines. It delivers 600 W peak pulse power (10/1000 μs), clamps at ≤9.2 V under 375 A surge, and exhibits ≤5.0 μA leakage at 5.0 V stand-off voltage - ideal for protecting USB interfaces, sensor I/O, and microcontroller GPIOs in consumer and industrial electronics.
For engineers reviewing the SMA6F5.0A-M3/6B datasheet, SMA6F5.0A-M3/6B pinout, SMA6F5.0A-M3/6B application, or SMA6F5.0A-M3/6B equivalent, key selection criteria include its 6.4–7.07 V breakdown range, 9.2 V max clamping at 375 A, unidirectional polarity, MSL Level 1 rating, and compatibility with automated SMT assembly on FR4 PCBs.
Technical Context
This TVS diode operates as a clamping device triggered by reverse-biased avalanche breakdown above its stand-off voltage (VWM = 5.0 V). Its low dynamic resistance (0.031 Ω) ensures rapid response to ESD and lightning-induced surges while maintaining tight clamping performance across temperature.
Designed for high-reliability board-level protection, it meets IEC 61000-4-2 Level 4 (±15 kV air / ±8 kV contact), supports reflow soldering up to 260 °C peak, and features matte tin-plated leads compliant with J-STD-002 and JESD22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 6.40 V / 7.07 V at 10 mA - guaranteed avalanche initiation window for predictable turn-on |
| VC @ IPPM | 9.2 V at 375 A (10/1000 μs) - peak clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 600 W (10/1000 μs) - energy-handling capability for common inductive-switching transients |
| ID @ VWM | ≤5.0 μA - negligible leakage current preserving signal integrity and power efficiency |
| TJ max | 175 °C - enables operation in high-temperature environments including automotive under-hood zones |
| Package | SlimSMA (DO-221AC) - 0.95 mm profile optimized for space-constrained layouts and high-density routing |

IC Role / Device Role / Timing Role: Absorbing up to 600 W of transient energy to prevent rail collapse or downstream regulator overvoltage shutdown. Use Value: Maintains system uptime during field-induced surges without requiring oversized bulk capacitance or secondary regulation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6F5.0A-M3/6A | Identical electrical specs; differs only in tape-and-reel packaging (3.5k vs. 14k units per reel) | No functional difference; same thermal, clamping, and reliability performance | Select based on production volume and pick-and-place feeder compatibility |
| SMAJ5.0A | Same VWM/VBR/VC specs but in larger SMA (DO-214AC) package (2.3 mm height vs. 0.95 mm) | Higher thermal mass but incompatible with ultra-low-profile designs; lower mounting density | Choose SMAJ5.0A only if board height budget allows ≥2.3 mm and higher surge margin is needed |
Compared with SMA6F5.0A-M3/6B, SMA6F5.0A-M3/6A offers identical protection performance in a smaller reel format, while SMAJ5.0A trades slimness for greater thermal dissipation - making SMA6F5.0A-M3/6B optimal for space-constrained, high-volume SMT deployments where profile and reflow compatibility are critical.

FAQ
What is the maximum clamping voltage of the SMA6F5.0A-M3/6B under a 10/1000 μs surge?
The SMA6F5.0A-M3/6B clamps to a maximum of 9.2 V when subjected to a 375 A peak pulse with a 10/1000 μs waveform. This value is measured at 25 °C and represents the upper limit of voltage imposed on the protected circuit during standardized surge testing - critical for ensuring downstream ICs remain within absolute maximum ratings.
Does the SMA6F5.0A-M3/6B meet IEC 61000-4-2 ESD immunity requirements?
Yes, the SMA6F5.0A-M3/6B is rated for IEC 61000-4-2 Level 4 ESD immunity: ±15 kV for air discharge and ±8 kV for contact discharge. This certification is verified per the manufacturer's test report and applies directly to the SMA6F5.0A-M3/6B device in its SlimSMA package, confirming suitability for end-equipment requiring certified ESD robustness.
What is the thermal resistance junction-to-ambient (RθJA) for the SMA6F5.0A-M3/6B on a standard FR4 PCB?
The SMA6F5.0A-M3/6B has a typical RθJA of 120 °C/W when mounted on an FR4 PCB with 2 oz. copper and standard footprint per JEDEC 51-2A. This value defines the steady-state temperature rise per watt of power dissipated - essential for calculating safe operating limits during sustained leakage or repeated low-energy transients.
Can the SMA6F5.0A-M3/6B be used in automotive applications?
Yes, the SMA6F5.0A-M3/6B supports automotive use cases due to its 175 °C maximum junction temperature, MSL Level 1 reflow rating, and qualification per AEC-Q200 stress test conditions (as part of the broader SMA6F family). It is commonly deployed in infotainment interfaces, body control modules, and sensor nodes where space and thermal constraints demand ultra-slim TVS solutions.
What does the "-M3/6B" suffix indicate in SMA6F5.0A-M3/6B?
The "-M3/6B" suffix denotes halogen-free, RoHS-compliant construction (M3) and 13-inch tape-and-reel packaging containing 14,000 units (6B). This distinguishes it from the -M3/6A variant (7-inch reel, 3,500 units) while retaining identical electrical, thermal, and mechanical specifications - enabling drop-in substitution based on production logistics needs.
