Product details
Overview
SM6T200A-M3/52 from Vishay General Semiconductor is a unidirectional surface-mount TRANSZORB® transient voltage suppressor in SMB (DO-214AA) package, with 171 V standoff voltage (VWM), 190–210 V breakdown voltage (VBR), and 600 W peak pulse power (10/1000 μs). It clamps transients to ≤274 V at 2.2 A and operates from −65 °C to +150 °C, protecting MOSFETs and sensor signal lines in automotive power systems.
For engineers reviewing the SM6T200A-M3/52 datasheet, SM6T200A-M3/52 pinout, SM6T200A-M3/52 application, or SM6T200A-M3/52 equivalent, key selection criteria include unidirectional polarity, 274 V max clamping voltage at rated IPPM, halogen-free RoHS-compliant construction (M3 suffix), and AEC-Q101 qualification eligibility via HM3 variant.
Technical Context
The SM6T200A-M3/52 is a silicon avalanche diode designed for unidirectional transient suppression in DC power rails and signal paths. Its glass-passivated junction ensures stable breakdown behavior under repetitive surge stress, and its low-inductance SMB package supports fast response to ESD and load-switching transients.
It delivers 600 W peak pulse power per 10/1000 μs waveform with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W, enabling reliable operation on standard 0.2" × 0.2" copper pads without forced cooling. The device is rated for IFSM = 100 A (10 ms half-sine) and meets J-STD-020 MSL Level 1.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200A-E3/52 | Same VWM/VBR/VC, but 400 W PPPM and SMA package (higher RθJA) | Limited to lower-energy transients; less suitable for automotive load-dump | Select when board space is constrained and surge energy is ≤400 W |
| SMCJ200A-M3 | Same electrical specs but SMC (DO-214AB) package - 30% larger footprint, lower RθJA (60 °C/W) | Better thermal performance for sustained surge duty cycles; requires larger pad area | Choose for high-reliability industrial systems where thermal margin >20 °C is required |
Compared with SMAJ200A-E3/52 and SMCJ200A-M3, the SM6T200A-M3/52 offers optimal balance of 600 W surge capacity, SMB footprint compatibility, and halogen-free compliance - making it preferred for space-constrained automotive modules requiring AEC-Q101 alignment.

FAQ
What is the maximum clamping voltage of the SM6T200A-M3/52 under a 10/1000 μs surge?
The SM6T200A-M3/52 has a maximum clamping voltage (VC) of 274 V when subjected to its rated peak pulse current of 2.2 A using a 10/1000 μs waveform. This value is guaranteed across temperature and production lot, and defines the upper voltage limit imposed on protected circuitry during transient events. The SM6T200A-M3/52 achieves this clamping performance while maintaining low leakage (<1 μA) at its 171 V standoff voltage.
Is the SM6T200A-M3/52 qualified to AEC-Q101?
The SM6T200A-M3/52 itself is not AEC-Q101 qualified; however, the HM3 variant (e.g., SM6T200AHM3_B/H) carries full AEC-Q101 qualification. The M3 suffix indicates halogen-free RoHS compliance only. For automotive applications requiring formal qualification, engineers must specify the HM3 suffix version - the SM6T200A-M3/52 remains suitable for non-qualified industrial use where the same electrical and thermal specs apply.
What does the "/52" suffix indicate in SM6T200A-M3/52?
"/52" denotes the preferred packaging configuration: 7" diameter plastic tape and reel containing 750 units. This format is optimized for high-speed automated placement equipment and aligns with IPC-7351 standards for SMB (DO-214AA) devices. The SM6T200A-M3/52 uses the same reel dimensions, carrier tape pitch, and pocket design as other Vishay SMB devices, ensuring compatibility with standard pick-and-place feeders.
Can the SM6T200A-M3/52 be used in bidirectional configurations?
No - the SM6T200A-M3/52 is strictly unidirectional, as indicated by the "A" suffix and cathode band marking. Bidirectional operation requires the "CA" suffix (e.g., SM6T200CA-M3/52), which features symmetrical breakdown in both polarities. Using the SM6T200A-M3/52 in reverse-biased mode beyond its 171 V standoff risks premature conduction and failure; always verify polarity during PCB layout and assembly.
What is the thermal resistance from junction to ambient for the SM6T200A-M3/52?
The SM6T200A-M3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes no additional heatsinking and defines the temperature rise above ambient at 5.0 W steady-state dissipation. For pulsed operation, transient thermal impedance curves (Fig. 5 in datasheet 88385) govern short-duration heating, allowing safe 600 W surges without exceeding 150 °C junction temperature.
