Product details
Overview
SMA6F13A-M3/6B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the SlimSMA (DO-221AC) package, designed for robust ESD and surge protection on signal lines and power rails. It features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR), 20.4 V clamping voltage at 13 A (10/1000 μs), 600 W peak pulse power, and IEC 61000-4-2 Level 4 ESD immunity (15 kV air / 8 kV contact). It is used to protect MOSFET gates, sensor interfaces, and microcontroller I/O in industrial and telecom equipment.
For engineers reviewing the SMA6F13A-M3/6B datasheet, SMA6F13A-M3/6B pinout, SMA6F13A-M3/6B application, or SMA6F13A-M3/6B equivalent, this page delivers verified electrical specs, thermal derating behavior, clamping performance under standardized transients, JEDEC-compliant MSL level 1 handling, and direct alternatives with documented parameter differences.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its VBR range (14.4–15.9 V at 1 mA). Its low dynamic resistance (0.153 Ω) ensures tight clamping during fast transients, while its 29.4 A peak pulse current rating (10/1000 μs) supports high-energy surge suppression without thermal runaway.
Thermal design is enabled by RθJA = 120–150 °C/W (FR4 PCB, 2 oz.) and RθJM = 12–15 °C/W, allowing operation up to TJ = 175 °C. The device meets J-STD-020 MSL level 1 and withstands lead-free reflow peaks of 260 °C, making it suitable for automated SMT assembly in high-reliability production environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before conduction begins; defines safe signal rail margin. |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - Breakdown threshold range; determines earliest clamping onset under overvoltage stress. |
| VC @ IPP = 13 A | 20.4 V (10/1000 μs) - Clamped voltage seen by protected circuit; must be below downstream IC absolute maximum ratings. |
| PPPM (10/1000 μs) | 600 W - Peak transient energy absorption capability; defines survivability against common lightning-induced surges. |
| ID @ VWM | 0.2 μA max - Reverse leakage at stand-off voltage; negligible loading on low-power sensor or logic lines. |
| TJ max. | 175 °C - Maximum junction temperature; enables use in high-ambient industrial enclosures without forced cooling. |
| ESD Rating | IEC 61000-4-2 Level 4: 15 kV air / 8 kV contact - Confirmed human-body-model immunity for front-panel and connector interfaces. |
Pinout & Package

|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes clamping path during transient events. |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., USB D+, RS-485 A); conducts avalanche current into anode when V > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Clamping voltage control | 20.4 V at 13 A (10/1000 μs) - Ensures protected ICs remain within safe operating area during 600 W surges. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6F13A-M3/H | Same electrical specs; differs only in tape-and-reel packaging (3500 pcs/reel, 7″ diameter vs. 14,000 pcs/reel, 13″ diameter). | No functional difference; suited for lower-volume prototyping or small-batch production where reel size impacts feeder compatibility. | Select SMA6F13A-M3/H when matching existing SMT line setup using 7″ reels or when minimizing initial inventory commitment. |
| SMA6F12A-M3/6B | Lower VWM (12 V), VBR (13.3–14.7 V), and VC (18.8 V @ 12 A); otherwise identical package, thermal, and ESD specs. | Better fit for 12 V nominal systems (e.g., automotive body electronics) where tighter clamping margin is required relative to rail voltage. | Choose SMA6F12A-M3/6B when protecting circuits with 12 V supply rails and stricter clamping headroom requirements than SMA6F13A-M3/6B provides. |
Compared with SMA6F13A-M3/6B, SMA6F13A-M3/H offers identical protection performance with smaller reel logistics, while SMA6F12A-M3/6B trades 1 V higher VWM for 1.6 V lower clamping voltage-enabling safer interface protection in 12 V systems but reducing margin against normal-mode ripple.

FAQ
What is the maximum clamping voltage of the SMA6F13A-M3/6B under a 10/1000 μs surge?
The SMA6F13A-M3/6B exhibits a maximum clamping voltage (VC) of 20.4 V when subjected to a 13 A peak pulse current with a 10/1000 μs waveform. This value is measured per the standard test condition specified in the Vishay datasheet (Document Number: 89458), and directly defines the upper voltage limit imposed on protected circuitry during such transients. Engineers must verify that this clamped voltage remains below the absolute maximum rating of downstream components.
Does the SMA6F13A-M3/6B support lead-free reflow soldering?
Yes, the SMA6F13A-M3/6B meets J-STD-020 MSL level 1 and is rated for lead-free reflow with a maximum peak temperature of 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD22-B102 solderability standards, and the device passes JESD201 Class 2 whisker testing. These qualifications confirm full compatibility with standard Pb-free SMT assembly processes without risk of delamination or intermetallic growth.
How does the SMA6F13A-M3/6B differ from the SMA6F13A-M3/H variant?
The SMA6F13A-M3/6B and SMA6F13A-M3/H share identical electrical, thermal, and mechanical specifications-including VWM (13 V), VBR (14.4–15.9 V), VC (20.4 V), package (SlimSMA/DO-221AC), and MSL level 1 rating. Their sole difference lies in packaging: SMA6F13A-M3/6B ships in 13″ reels (14,000 pcs), while SMA6F13A-M3/H uses 7″ reels (3500 pcs). No design or performance trade-offs exist between them.
What is the reverse leakage current of the SMA6F13A-M3/6B at its stand-off voltage?
At its 13 V stand-off voltage (VWM), the SMA6F13A-M3/6B specifies a maximum reverse leakage current (ID) of 0.2 μA at TA = 25 °C. This ultra-low leakage ensures minimal DC loading on sensitive analog or low-power digital signal paths-such as those found in battery-operated sensor nodes or precision instrumentation-without affecting baseline operating conditions or power budget calculations.
Can the SMA6F13A-M3/6B be used in bidirectional protection configurations?
No, the SMA6F13A-M3/6B is explicitly a unidirectional TVS diode, as confirmed in the Vishay datasheet's FEATURES section ("Unidirectional only"). It conducts only in reverse bias above VBR and blocks forward current like a standard diode. For bidirectional surge protection (e.g., AC lines or differential buses), a dedicated bidirectional TVS such as the SMA6F13CA-M3/6B-or back-to-back unidirectional devices-must be used instead.
