Product details
Overview
SM15T200CA-M3/9AT from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) in SMC (DO-214AB) package, rated for 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), and 1500 W peak pulse power (10/1000 μs). It clamps transients to 274 V at 5.5 A IPPM and operates from −65 °C to +150 °C, protecting automotive sensor signal lines against lightning-induced surges.
For engineers reviewing the SM15T200CA-M3/9AT datasheet, SM15T200CA-M3/9AT pinout, SM15T200CA-M3/9AT application, or SM15T200CA-M3/9AT equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal resistance (RθJA = 75 °C/W), halogen-free RoHS compliance (M3 suffix), and AEC-Q101 qualification context for automotive-grade design validation.
Technical Context
The SM15T200CA-M3/9AT employs a glass-passivated silicon junction optimized for bidirectional surge suppression with symmetrical clamping in both polarities. Its 10/1000 μs waveform rating of 1500 W and low clamping ratio (VC/VBR ≈ 1.25) ensure robust protection against high-energy transients without forward conduction during normal operation.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads, it achieves RθJL = 15 °C/W and meets MSL Level 1 (260 °C peak reflow), supporting automated placement in automotive ECUs and industrial I/O modules where high source impedance limits peak current within its 5.5 A IPPM rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 200 V - Maximum continuous reverse operating voltage before clamping begins; defines system-level DC bias margin. |
| VBR (min) | 220 V - Minimum breakdown voltage at 1 mA test current; ensures reliable turn-on above normal operating voltage. |
| VC @ IPPM | 274 V at 5.5 A - Clamped voltage under 10/1000 μs surge; determines maximum stress imposed on downstream ICs. |
| PPPM | 1500 W - Peak pulse power handling capability; supports lightning and inductive-switching threat models per IEC 61000-4-5. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on standard pad layout; enables thermal derating up to 150 °C TJ max. |
| Package | SMC (DO-214AB) - Industry-standard surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height; compatible with AOI and reflow. |
| Compliance | Halogen-free, RoHS-compliant (M3 suffix), AEC-Q101 qualified - Meets automotive reliability and environmental requirements. |
Pinout & Package
SM15T200CA-M3/9AT uses the SMC (DO-214AB) package: a two-terminal, bidirectional device with no polarity marking. Terminals are matte tin-plated leads solderable per J-STD-002 and JESD 22-B102, mounted on 8.0 mm × 8.0 mm copper pads per datasheet recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode / Cathode (bidirectional) | Non-polarized connection point; functions as either anode or cathode depending on transient polarity; no band marking. |
| Terminal 2 | Anode / Cathode (bidirectional) | Identical function to Terminal 1; symmetric construction enables equal clamping in both directions. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional 1500 W surge rating | Enables single-device protection of AC-coupled or floating signal lines without polarity constraints. |
| 274 V clamping voltage at 5.5 A | Limits voltage overshoot to safe levels for 3.3 V/5 V/12 V interface ICs in automotive sensor front-ends. |
| MSL Level 1 (260 °C peak) | Supports lead-free reflow without moisture sensitivity concerns, eliminating bake requirements pre-assembly. |
| Halogen-free & RoHS-compliant (M3) | Fulfills automotive OEM material declarations (IMDS, CAMDS) and end-of-life recycling mandates. |
| AEC-Q101 qualified variant available | Validated for automotive underhood applications including engine control, ADAS sensors, and body electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200CA | Lower PPPM (600 W), same VWM/VBR range, SMB package (smaller footprint, higher RθJA = 110 °C/W) | Preferred for space-constrained consumer designs with lower surge threat severity (IEC 61000-4-2 only) | Select SMBJ200CA when board area is critical and peak surge energy remains below 600 W. |
| 1.5KE200CA | Higher IPPM (7.2 A), same VWM/VBR, axial DO-201 package (through-hole, manual assembly) | Suitable for legacy industrial equipment requiring through-hole reliability and higher mechanical robustness | Choose 1.5KE200CA for retrofit designs or high-vibration environments where SMT adhesion is a concern. |

FAQ
What does the "CA" suffix indicate in SM15T200CA-M3/9AT?
The "CA" suffix in SM15T200CA-M3/9AT denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression in both polarities without polarity marking. This differs from unidirectional variants (e.g., SM15T200A) that require correct cathode orientation and exhibit forward conduction in one direction. SM15T200CA-M3/9AT is used where AC signals or floating references demand polarity-agnostic clamping.
Is SM15T200CA-M3/9AT suitable for automotive applications?
Yes, SM15T200CA-M3/9AT is halogen-free and RoHS-compliant (M3 suffix), and its base family is AEC-Q101 qualified. While the exact part number SM15T200CA-M3/9AT corresponds to the commercial-grade variant, it shares identical electrical and thermal specifications with AEC-Q101 versions (e.g., SM15T200CAHM3_X), making it suitable for automotive use when sourced with appropriate qualification documentation and traceability.
What is the clamping voltage of SM15T200CA-M3/9AT under surge conditions?
The SM15T200CA-M3/9AT clamps to a maximum of 274 V when subjected to its rated peak pulse current of 5.5 A using the industry-standard 10/1000 μs waveform. This clamping voltage is measured across the terminals during transient events and defines the upper voltage limit imposed on protected circuitry, ensuring compatibility with 200 V-rated downstream components.
How does the SMC package of SM15T200CA-M3/9AT compare to DO-214AB?
The SMC package used by SM15T200CA-M3/9AT is identical to DO-214AB per JEDEC standards - both refer to the same physical outline with 7.75 mm × 6.22 mm body size and 2.62 mm height. Vishay uses "SMC" as its proprietary designation for this case style; no dimensional or thermal performance difference exists between SMC and DO-214AB for SM15T200CA-M3/9AT.
What is the maximum operating temperature for SM15T200CA-M3/9AT?
The SM15T200CA-M3/9AT has a specified operating junction temperature range of −65 °C to +150 °C. Its thermal resistance (RθJA = 75 °C/W) allows operation at full power up to +125 °C ambient when mounted on the recommended 8.0 mm × 8.0 mm copper pads, with linear derating applied above 25 °C per Figure 2 in the datasheet.
