Product details
Overview
SMA6F60A-M3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in SlimSMA (DO-221AC) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It delivers 600 W peak pulse power (10/1000 μs), clamps at 96.8 V under 60 A surge current, and features 60 V stand-off voltage with ≤0.2 μA leakage at 25 °C - ideal for protecting MOSFETs and signal lines in industrial sensor interfaces.
For engineers reviewing the SMA6F60A-M3/H datasheet, SMA6F60A-M3/H pinout, SMA6F60A-M3/H application, or SMA6F60A-M3/H equivalent, key selection criteria include its 60 V stand-off voltage, 96.8 V max clamping voltage at 60 A (10/1000 μs), unidirectional polarity, SlimSMA package compatibility with automated placement, and IEC 61000-4-2 Level 4 ESD rating (15 kV air / 8 kV contact).
Technical Context
This TVS diode operates as a voltage-clamped overvoltage protection device, leveraging Zener avalanche breakdown to divert transient energy away from downstream circuitry. Its unidirectional configuration provides forward conduction capability while maintaining precise reverse stand-off and sharp breakdown characteristics.
Designed for high-energy surge suppression, it sustains 4 kW peak pulse power under 8/20 μs waveform and exhibits low dynamic resistance (3.73 Ω) to minimize clamping voltage overshoot during fast transients. Thermal performance is characterized by RθJA = 120–150 °C/W on FR4 PCB and maximum junction temperature of 175 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6F60AHE3/52 (Vishay) | Same electrical specs; differs in packaging (tape-and-reel vs. bulk) and MSL level (Level 1 vs. Level 1 confirmed), no functional difference | Identical protection function; suited for same PCB layouts and thermal environments | Select based on procurement channel preference and volume packaging requirements |
| SMCJ60A (Bourns) | Higher package size (DO-214AB), 1500 W (10/1000 μs), 100 A IPP, 102 V clamping - larger footprint, higher surge rating | Better suited for high-energy industrial mains input stages where board space allows larger case | Choose SMA6F60A-M3/H when SlimSMA footprint and 0.95 mm height are mandatory; choose SMCJ60A when higher surge margin justifies larger area |
Compared with SMA6F60AHE3/52, the SMA6F60A-M3/H offers identical electrical performance and SlimSMA packaging but with M3 halogen-free compliance and JESD201 Class 2 whisker testing - critical for industrial-grade production. Against SMCJ60A, it trades surge capacity for compactness: 600 W vs. 1500 W, yet fits in 40% less PCB area and enables thinner end-equipment designs.

FAQ
What is the maximum clamping voltage of the SMA6F60A-M3/H under a 10/1000 μs surge?
The SMA6F60A-M3/H has a maximum clamping voltage (VC) of 96.8 V when subjected to a 60 A peak pulse current with a 10/1000 μs waveform. This value is measured per standard test conditions in the Vishay datasheet (Document Number: 89458) and defines the upper voltage limit imposed on protected circuitry during that specific transient event. The SMA6F60A-M3/H maintains this clamping performance across its specified operating temperature range.
Does the SMA6F60A-M3/H meet automotive ESD requirements?
Yes, the SMA6F60A-M3/H meets IEC 61000-4-2 Level 4 ESD immunity: 15 kV air discharge and 8 kV contact discharge. While not AEC-Q200 qualified as a standalone component, its robust ESD performance makes it suitable for non-safety-critical automotive subsystems such as body control modules and sensor interfaces where system-level ESD testing is performed. The SMA6F60A-M3/H is widely deployed in automotive applications requiring certified ESD hardening.
What is the thermal resistance of the SMA6F60A-M3/H on a standard FR4 PCB?
The SMA6F60A-M3/H has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on an FR4 PCB with 2 oz. copper and standard footprint, per JEDEC 51-2A. Maximum RθJA is specified as 150 °C/W under the same conditions. This thermal characteristic directly impacts power derating above 25 °C ambient and must be used to calculate safe operating limits in thermally constrained layouts. The SMA6F60A-M3/H's SlimSMA package contributes to this moderate thermal resistance despite its low profile.
Is the SMA6F60A-M3/H unidirectional or bidirectional?
The SMA6F60A-M3/H is a unidirectional TVS diode, meaning it conducts only in reverse breakdown (cathode-to-anode) and behaves as a high-impedance open circuit in forward bias. Its polarity is marked by a cathode band on the package. This configuration is appropriate for DC-biased lines such as power rails and digital I/O where forward conduction does not interfere with normal operation. The SMA6F60A-M3/H is not suitable for AC signal lines requiring symmetrical clamping.
What does the "-M3/H" suffix indicate in SMA6F60A-M3/H?
The "-M3" suffix denotes halogen-free, RoHS-compliant construction with matte tin-plated leads meeting J-STD-002 solderability and JESD201 Class 2 whisker resistance. The "/H" indicates the preferred package code for SMA6F60A-M3/H per Vishay's ordering information - specifying 7-inch tape-and-reel delivery with 3500 units per reel. Together, "-M3/H" fully identifies the environmental compliance, plating, and packaging format of the SMA6F60A-M3/H variant.
