Product details
Overview
SMA6F60A-M3/I 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 power and signal lines. It delivers 600 W peak pulse power (10/1000 μs), 4 kW (8/20 μs), with breakdown voltage VBR = 66.7–73.7 V at 1 mA, clamping voltage VC = 96.8 V at 60 A, and operates across -55 °C to +175 °C junction temperature.
For engineers reviewing the SMA6F60A-M3/I datasheet, SMA6F60A-M3/I pinout, SMA6F60A-M3/I application, or SMA6F60A-M3/I equivalent, this device is selected for robust ESD and surge protection in industrial sensor interfaces, automotive body electronics, and telecom power rails where low-profile mounting and high-energy transient suppression are required.
Technical Context
This TVS diode operates as a unidirectional Zener-based clamp, activated when reverse voltage exceeds VWM = 60 V and VBR threshold. Its dynamic resistance RD = 3.73 Ω enables precise clamping behavior under fast transients, while thermal resistance RθJA = 120–150 °C/W (FR4 PCB) supports reliable power dissipation up to 8 W at TM = 55 °C.
It meets IEC 61000-4-2 Level 4 ESD immunity (15 kV air / 8 kV contact), complies with J-STD-020 MSL Level 1, and features matte tin-plated leads solderable per J-STD-002 and JESD22-B102. The cathode band denotes polarity, and the SlimSMA package enables automated placement with 0.95 mm typical height.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse stand-off voltage before clamping initiates |
| VBR (min/max) | 66.7 V / 73.7 V at 1 mA - Confirmed breakdown range ensures consistent turn-on across production lots |
| VC @ IPP = 60 A | 96.8 V - Clamping voltage during 10/1000 μs surge limits downstream IC stress to safe levels |
| PPPM (10/1000 μs) | 600 W - Sustains high-energy transients common in automotive load-dump and inductive switching |
| PPPM (8/20 μs) | 4000 W - Handles lightning-induced surges per IEC 61000-4-5 without failure |
| ID @ VWM | 0.2 μA max - Ultra-low leakage preserves battery life and signal integrity in always-on circuits |
| TJ range | -55 °C to +175 °C - Supports operation in under-hood automotive and industrial environments |
Pinout & Package
Package: SlimSMA (DO-221AC), surface-mount, 2-terminal unidirectional configuration. Cathode denoted by color band; anode is opposite end. Dimensions: 4.15–4.35 mm length × 2.50–2.70 mm width × 0.95 mm typical height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction; connected to protected line ground or low-side reference | Provides return path for clamped surge current; must be routed with low-inductance trace to minimize overshoot |
| Cathode | Current exit point during reverse clamping; connected to protected line (e.g., 60 V rail or signal) | Acts as high-impedance input until VBR exceeded; color band enables automated optical inspection and orientation verification |

|---|---|
Use Scenario: Protects LIN bus transceivers and microcontroller I/O pins from load-dump transients during battery disconnect/reconnect events. IC Role / Device Role / Timing Role: Unidirectional TVS clamps reverse voltage spikes on 12 V supply rail and LIN data line to prevent latch-up or gate oxide damage. Use Value: With VC = 96.8 V and 600 W rating, it holds rail voltage below 100 V during 100 ms load-dump pulses, preserving MCU functionality. |
Use Scenario: Shields analog front-end amplifiers and ADC inputs of pressure/temperature sensors from ESD and cable discharge events. IC Role / Device Role / Timing Role: Placed at connector interface to shunt >15 kV air-gap ESD strikes before reaching precision op-amps.

Use Scenario: Guards AC/DC adapter output stage against induced surges from nearby lightning strikes or grid switching noise. IC Role / Device Role / Timing Role: Mounted directly at DC output connector to clamp 4 kV (8/20 μs) transients before reaching PMIC and SoC. Use Value: 4000 W peak power rating ensures survivability of telecom-grade surge tests without degradation over 1000+ events. |
Use Scenario: Suppresses back-EMF spikes generated by brushed DC motors in washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Connected across motor terminals to absorb inductive energy during MOSFET turn-off transitions. Use Value: 600 W (10/1000 μs) capability handles repetitive 50–100 ms spikes without thermal runaway, extending driver IC lifetime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6F60A-M3/6B | Same electrical specs; differs only in tape-and-reel packaging (14,000 pcs/reel, 13″ diameter vs. SMA6F60A-M3/I's 14,000 pcs/reel, 13″ diameter with "I" carrier code) | No functional difference; identical performance and footprint | Select SMA6F60A-M3/6B if legacy BOM references "6B" or if using existing reel-handling tooling calibrated for that code |
| SMAJ60A-M3/5B | Higher PPPM = 400 W (10/1000 μs); larger SMA (DO-214AC) package; VC = 96.8 V same, but RD = 1.2 Ω lower | Less suitable for ultra-thin designs due to 2.3 mm height; better for higher-current surge scenarios requiring lower clamping impedance | Choose SMAJ60A-M3/5B only when board layout allows taller profile and system-level testing confirms need for sub-1 Ω dynamic resistance |
Compared with SMA6F60A-M3/I, SMA6F60A-M3/6B offers identical protection performance in alternate tape format, while SMAJ60A-M3/5B trades slimness for marginally improved clamping linearity-making SMA6F60A-M3/I optimal for height-sensitive, high-volume automated assembly.

FAQ
What is the maximum clamping voltage of the SMA6F60A-M3/I under a 60 A, 10/1000 μs surge?
The SMA6F60A-M3/I has a maximum clamping voltage VC of 96.8 V when subjected to a 60 A peak pulse with 10/1000 μs waveform. This value is measured per standard test conditions in the Vishay datasheet (Document Number: 89458) and reflects the actual voltage seen by downstream circuitry during worst-case transient events. The SMA6F60A-M3/I maintains this clamping level consistently across its operating temperature range.
Does the SMA6F60A-M3/I meet automotive qualification standards such as AEC-Q200?
The SMA6F60A-M3/I is not explicitly qualified to AEC-Q200 in its base specification, but it satisfies key prerequisites including JESD201 Class 2 whisker resistance, MSL Level 1, and 175 °C maximum junction temperature-enabling successful qualification by end customers for automotive body electronics. Vishay provides supporting reliability data for the SlimSMA platform, and the SMA6F60A-M3/I is widely deployed in Tier-1 automotive modules where full AEC-Q200 validation is completed at system level.
Can the SMA6F60A-M3/I be used in bidirectional configurations?
No, the SMA6F60A-M3/I is strictly unidirectional and must be installed with correct polarity-cathode toward the protected line. It does not provide symmetrical clamping for AC signals or reverse-polarity transients. For bidirectional protection, a dedicated bidirectional TVS like SMA6F60CA-M3/I or paired unidirectional devices would be required. Using SMA6F60A-M3/I in reverse orientation risks permanent breakdown.
What is the thermal resistance junction-to-ambient (RθJA) for the SMA6F60A-M3/I on a standard FR4 PCB?
The SMA6F60A-M3/I exhibits a typical RθJA of 120 °C/W and a maximum of 150 °C/W when mounted on a standard FR4 PCB with 2 oz. copper and the recommended pad layout. This value is defined per JEDEC 51-2A and directly impacts power derating above 55 °C ambient. At 85 °C ambient, the SMA6F60A-M3/I's usable power dissipation drops to approximately 4.3 W based on this thermal resistance.
How does the leakage current of the SMA6F60A-M3/I compare to other 60 V TVS diodes in the same family?
The SMA6F60A-M3/I specifies a maximum reverse leakage current ID of 0.2 μA at VWM = 60 V and 25 °C-matching the leakage performance of all SMA6FxxA variants rated ≥22 V. This ultra-low leakage is critical for battery-powered sensor nodes and high-impedance analog circuits, where even nanoamp-level currents can cause measurement drift or premature battery depletion. The SMA6F60A-M3/I maintains this spec across its full temperature range.
