Product details
Overview
SM6T200CA-M3/52 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, rated for 200 V standoff voltage (VWM), 274 V maximum clamping voltage (VC) at 2.2 A IPPM, and 600 W peak pulse power with 10/1000 μs waveform. It provides robust ESD and surge protection for automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the SM6T200CA-M3/52 datasheet, SM6T200CA-M3/52 pinout, SM6T200CA-M3/52 application, or SM6T200CA-M3/52 equivalent, key selection criteria include bidirectional clamping symmetry, low clamping ratio (VC/VBR ≈ 1.30), halogen-free RoHS compliance (M3 suffix), and AEC-Q101 qualification readiness via HM3 variant.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding to transients above its 200 V stand-off threshold by entering avalanche breakdown in both polarities. Its glass-passivated junction ensures stable VBR (190–210 V) and low leakage (<1 μA at VWM).
Designed for surface-mount placement on PCBs with 5.0 mm × 5.0 mm copper pads per terminal, it delivers 600 W pulse handling under JEDEC-standard 10/1000 μs waveform while maintaining thermal resistance RθJA = 100 °C/W and operating up to TJ = 150 °C.

| Glass-passivated junction | Ensures long-term stability of breakdown voltage and low leakage across temperature and lifetime |
| Low-inductance SMB package | Minimizes voltage overshoot during fast transients (e.g., ESD ±30 kV contact discharge) |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and inductive switching transients in 12 V/24 V vehicle systems. IC Role / Device Role / Timing Role: Shunt clamping element placed directly at connector or IC input pins to divert surge current away from sensitive circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200CA | Same VWM (200 V), lower PPPM (400 W), SMA package (higher RθJA = 140 °C/W) | Limited to lower-energy transients; less suitable for automotive load dump | Select when cost sensitivity outweighs peak power requirement and board space allows larger thermal pads |
| SMCJ200CA | Same VWM (200 V), higher PPPM (1500 W), SMC package (larger footprint, lower RθJA = 35 °C/W) | Better thermal performance but requires 2.5× PCB area; overqualified for compact consumer designs | Choose for high-reliability industrial power supplies where sustained surge duty cycle exceeds SM6T rating |
Compared with SMAJ200CA and SMCJ200CA, SM6T200CA-M3/52 offers optimal balance of 600 W surge capacity, SMB footprint efficiency, and halogen-free compliance-making it ideal for space-constrained automotive and industrial control boards requiring AEC-Q101-ready variants.

FAQ
What is the breakdown voltage range for SM6T200CA-M3/52?
The SM6T200CA-M3/52 has a guaranteed breakdown voltage (VBR) range of 190 V to 210 V at test current IT = 1.0 mA, measured in both directions due to its bidirectional construction. This specification is confirmed in the Vishay SM6T datasheet revision 09-Jan-2024, page 2, Electrical Characteristics table.
Is SM6T200CA-M3/52 suitable for automotive applications?
Yes, SM6T200CA-M3/52 is halogen-free and RoHS-compliant (M3 suffix); an AEC-Q101 qualified version is available as SM6T200CA-HM3_X. While the M3 variant itself is not certified, its construction, thermal specs (TJ max = 150 °C), and electrical parameters align with automotive transient protection requirements such as ISO 7637-2 and ISO 16750-2.
What does the "CA" suffix indicate in SM6T200CA-M3/52?
The "CA" suffix in SM6T200CA-M3/52 explicitly denotes a bidirectional configuration, meaning the device provides symmetrical clamping in both positive and negative polarities. This distinguishes it from unidirectional variants (e.g., SM6T200A) and ensures suitability for AC signal lines, differential buses, or floating nodes where polarity reversal may occur.
What is the maximum clamping voltage of SM6T200CA-M3/52 under standard test conditions?
The SM6T200CA-M3/52 exhibits a maximum clamping voltage (VC) of 274 V when subjected to a 10/1000 μs waveform at peak pulse current IPPM = 2.2 A, as specified in the Vishay SM6T datasheet (Document Number: 88385, page 2). This value defines the upper voltage limit imposed on protected circuitry during surge events.
Does SM6T200CA-M3/52 require special PCB layout considerations?
Yes, SM6T200CA-M3/52 must be mounted on minimum recommended copper pads: 0.2" × 0.2" (5.0 mm × 5.0 mm) per terminal, as stated in the datasheet's Maximum Ratings section. Deviating from this layout increases thermal resistance and reduces achievable PPPM, potentially leading to premature failure during repetitive surge events.
