Product details
Overview
1.5SMC200CA-M3/9AT from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 200 V standoff voltage (VWM), 220 V minimum breakdown voltage (VBR), 1500 W peak pulse power (10/1000 µs), clamping voltage of 328 V at 4.6 A, and operates across -65 °C to +150 °C. It is used to protect MOSFETs, sensor interfaces, and automotive ECUs against lightning-induced transients and inductive switching surges.
For engineers reviewing the 1.5SMC200CA-M3/9AT datasheet, 1.5SMC200CA-M3/9AT pinout, 1.5SMC200CA-M3/9AT application, or 1.5SMC200CA-M3/9AT equivalent, key selection criteria include bidirectional clamping capability, SMC (DO-214AB) package compatibility, 328 V max clamping at rated IPPM, AEC-Q101 qualification eligibility (via HM3 suffix), and halogen-free RoHS compliance per M3 grading.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction to achieve fast response (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 µs transients at 0.01% duty cycle. Its symmetrical I-V characteristics enable identical protection in both polarities without polarity marking.
Thermally, it exhibits RθJA = 75 °C/W and RθJL = 15 °C/W, supporting reliable operation on standard 8.0 mm × 8.0 mm copper pads. It meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements, with matte tin-plated leads solderable per J-STD-002 and JESD22-B102.

Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed control modules (e.g., body ECUs, lighting drivers) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Primary shunt clamp placed upstream of DC-DC converters and LDOs to limit transient voltage to safe levels. Use Value: Clamps to 328 V during 1500 W surges, preventing damage to downstream 36 V-rated regulators and microcontrollers. |
Use Scenario: Safeguarding analog front-ends of pressure, temperature, or position sensors connected to long harnesses in factory automation. IC Role / Device Role / Timing Role: Bidirectional TVS placed across differential signal pairs (e.g., RS-485, CAN FD stubs) to suppress ESD and inductive kickback. Use Value: Symmetrical clamping ensures equal protection on both signal lines without polarity dependency - critical for floating bus topologies. |
| Telecom Power Feeds | Consumer Appliance Motor Control |
Use Scenario: Overvoltage suppression on PoE-powered devices (e.g., IP cameras, VoIP phones) subjected to lightning-induced surges on Ethernet cables. IC Role / Device Role / Timing Role: Secondary-level TVS installed after primary gas discharge tube (GDT), absorbing residual energy not diverted by coarse protection. Use Value: Fast <1 ns response captures high-frequency surge components missed by slower GDTs, reducing let-through voltage to sub-350 V. |
Use Scenario: Protecting gate drivers and MCU I/O pins in washing machine or HVAC blower motor inverters exposed to back-EMF from brushed/BLDC motors. IC Role / Device Role / Timing Role: Clamp placed across motor phase outputs and across VDD/GND rails of half-bridge drivers to absorb commutation spikes. Use Value: 1500 W rating handles repetitive 10/1000 µs spikes from frequent motor starts/stops - validated for >100,000 cycles per JESD22-A108. |
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 | Same VWM/VBR/VC specs but lower PPPM (600 W); SMB package (smaller footprint, higher RθJA) | Limited to lower-energy transients (IEC 61000-4-5 Level 2); unsuitable for automotive load dump | Select when board space is constrained and surge threat level is ≤600 W. |
| 1.5KE200CA | Same electrical specs but axial DO-15 package; higher RθJA (100 °C/W); not SMT-compatible | Requires through-hole assembly; incompatible with automated pick-and-place; limited thermal performance on PCB | Choose only for legacy through-hole designs where rework to SMT is impractical. |
Compared with SMBJ200CA and 1.5KE200CA, the 1.5SMC200CA-M3/9AT delivers superior surge robustness (1500 W vs. 600 W or axial-limited thermal dissipation) in an industry-standard SMC package, enabling automated manufacturing, tighter thermal management, and compliance with AEC-Q101-ready variants.

FAQ
What is the maximum clamping voltage of the 1.5SMC200CA-M3/9AT under rated surge conditions?
The 1.5SMC200CA-M3/9AT has a maximum clamping voltage (VC) of 328 V when subjected to its rated peak pulse current of 4.6 A using the standard 10/1000 µs waveform. This value is measured at TA = 25 °C on specified 8.0 mm × 8.0 mm copper pads and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the 1.5SMC200CA-M3/9AT suitable for automotive applications?
Yes - the 1.5SMC200CA-M3/9AT is halogen-free and RoHS-compliant per M3 grading, and its base series is AEC-Q101 qualified (with HM3 suffix variants). While the M3 suffix itself denotes commercial-grade construction, the underlying 1.5SMC200CA die and SMC package meet automotive reliability requirements, making it suitable for non-safety-critical automotive subsystems like body electronics and infotainment power rails.
Does the 1.5SMC200CA-M3/9AT have polarity markings?
No - the 1.5SMC200CA-M3/9AT is a bidirectional TVS diode and carries no cathode band or polarity marking. Its symmetrical structure provides identical clamping behavior in both directions, eliminating orientation constraints during placement and simplifying layout for AC-coupled or floating signal lines.
What is the thermal resistance from junction to ambient for the 1.5SMC200CA-M3/9AT?
The 1.5SMC200CA-M3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 8.0 mm × 8.0 mm copper pad per terminal. This value assumes still air conditions and is critical for calculating maximum power dissipation limits at elevated ambient temperatures per Figure 2 in the Vishay datasheet 88303.
How does the 1.5SMC200CA-M3/9AT differ from unidirectional variants like 1.5SMC200A-M3/9AT?
The 1.5SMC200CA-M3/9AT is bidirectional with symmetrical breakdown and clamping in both polarities, while the unidirectional 1.5SMC200A-M3/9AT conducts only in reverse bias and features a cathode band. The "CA" suffix indicates bidirectional functionality - essential for protecting AC signals, differential buses, or circuits where voltage polarity reversal may occur during transients.
