Product details
Overview
1.5SMC200CA-E3/9AT from Vishay General Semiconductor is a bidirectional surface-mount 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), clamps to ≤274 V at 5.5 A peak pulse current, and operates across –65 °C to +150 °C - deployed in automotive sensor interfaces and industrial power supply rails.
For engineers reviewing the 1.5SMC200CA-E3/9AT datasheet, 1.5SMC200CA-E3/9AT pinout, 1.5SMC200CA-E3/9AT application, or 1.5SMC200CA-E3/9AT equivalent, this page delivers verified electrical specs, SMC (DO-214AB) package details, bidirectional clamping behavior, thermal derating curves, and RoHS-compliant commercial-grade sourcing support - all validated against Vishay Document #88303 (Rev. 09-Mar-2026).
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 characteristic enables identical protection in both polarities without polarity marking.
Rated for 1500 W peak pulse power with 274 V maximum clamping voltage at 5.5 A IPPM, it sustains 6.5 W steady-state power on infinite heatsink at 50 °C and exhibits 75 °C/W junction-to-ambient thermal resistance - enabling direct PCB-level placement on 8.0 mm × 8.0 mm copper pads per Vishay's recommended layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 200 V - Maximum continuous reverse voltage before conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown) | 220 V min - Voltage at which device enters avalanche breakdown at 1 mA test current; ensures reliable triggering above normal operating range. |
| VC (Clamping) | 274 V max at 5.5 A - Peak voltage seen by protected circuit during 10/1000 µs transient; determines downstream component stress level. |
| PPPM | 1500 W - Peak transient energy absorption capability; supports high-energy surges like lightning-induced spikes or inductive kickback. |
| TJ max | +150 °C - Maximum junction temperature; allows operation in under-hood automotive or high-ambient industrial environments. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance; informs PCB copper area requirements for thermal management without heatsinks. |
| Package | SMC (DO-214AB) - Surface-mount package with 3.2 mm × 6.2 mm body and 2.06 mm height; compatible with automated pick-and-place and reflow soldering. |
Pinout & Package
Package: SMC (DO-214AB), bidirectional configuration - no polarity marking; symmetrical terminals function as interchangeable anode/cathode pair.
| Pin/Terminal | Circuit Role | Design Meaning |

| MSL Level 1 (260 °C peak reflow) | Supports standard lead-free reflow profiles without moisture-related popcorn failure during assembly. |
| RoHS-compliant, commercial grade (E3 suffix) | Meets EU RoHS Directive 2011/65/EU and JESD201 Class 2 whisker resistance; suitable for consumer and industrial production. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients, improving protection fidelity for sensitive ICs and MOSFETs. |
Applications
| Automotive Sensor Protection | Industrial Power Supply Input |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends from ESD and load-dump transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across differential signal pair or supply rail to shunt surge energy to ground. Use Value: Maintains signal integrity by limiting transient voltage to ≤274 V while surviving repeated 1500 W pulses - critical for AEC-Q101-aligned designs using 1.5SMC200CA-E3/9AT variants. |
Use Scenario: Safeguarding 24 V DC input stages of PLCs and motor drives against inductive switching spikes and lightning surges. IC Role / Device Role / Timing Role: Primary overvoltage suppression device mounted directly at connector entry point, upstream of bulk capacitance. Use Value: Clamps 200 V nominal rail to 274 V during 10/1000 µs events, preventing damage to downstream DC-DC controllers rated for ≤300 V absolute maximum. |
| Telecom Line Interface | Consumer Appliance Control Board |
Use Scenario: Shielding Ethernet PHYs and PoE injectors from induced surges on outdoor cabling in security or networking equipment. IC Role / Device Role / Timing Role: Secondary protection stage after gas discharge tube (GDT), providing low-clamp, fast-response backup clamping. Use Value: Delivers sub-1 ns response and 274 V clamping to complement slower primary protectors - ensuring compliance with IEC 61000-4-5 Level 4 (4 kV) testing when used in cascade. |
Use Scenario: Securing microcontroller I/O lines and relay driver circuits in washing machines, HVAC controls, and smart home hubs. IC Role / Device Role / Timing Role: Point-of-use TVS on relay coil flyback paths and button debounce inputs to suppress contact bounce and ESD. Use Value: Enables compact SMC footprint with 200 V standoff - sufficient for 24 V control logic while eliminating need for discrete Zener+capacitor networks. |
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 peak power rating (600 W vs. 1500 W); SMB package (smaller footprint, higher RθJA = 110 °C/W) | Better suited for space-constrained, lower-energy applications (e.g., USB data lines); insufficient for 24 V industrial rail protection. | Select SMBJ200CA only where board area is critical and transient energy remains below 600 W - verify clamping margin with actual surge profile. |
| 1.5KE200CA | Through-hole DO-201 package; identical 200 V VWM and 274 V VC, but higher mounting inductance and manual assembly requirement | Preferred for prototyping or legacy through-hole designs; not suitable for high-volume SMT production. | Choose 1.5KE200CA for breadboarding or repair scenarios requiring hand-soldered replacement - avoid in new SMT designs targeting automated manufacturing. |
Compared with SMBJ200CA and 1.5KE200CA, the 1.5SMC200CA-E3/9AT uniquely balances high 1500 W surge capacity, SMT manufacturability, and 200 V system-level standoff - making it optimal for volume-produced automotive and industrial electronics where both energy handling and assembly efficiency matter.

FAQ
What is the standoff voltage (VWM) and breakdown voltage (VBR) of the 1.5SMC200CA-E3/9AT?
The 1.5SMC200CA-E3/9AT has a standoff voltage (VWM) of 200 V - the maximum DC or RMS voltage it blocks continuously - and a minimum breakdown voltage (VBR) of 220 V at 1 mA test current. These values confirm its suitability for protecting 200 V-class systems, such as 24 V industrial supplies with safety margins, and are measured per Vishay Document #88303 Section 2.
Is the 1.5SMC200CA-E3/9AT unidirectional or bidirectional?
The 1.5SMC200CA-E3/9AT is a bidirectional TVS diode, indicated by the "CA" suffix. It provides symmetrical clamping in both polarities with identical VWM, VBR, and VC characteristics - ideal for AC lines, differential signals, or any application where voltage polarity reversal may occur. No cathode band marking is present on the SMC package.
What does the "E3/9AT" suffix mean in 1.5SMC200CA-E3/9AT?
The "E3" denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 and JESD22-B102 solderability standards. The "9AT" specifies packaging: 3500 units per 13-inch diameter plastic tape-and-reel - optimized for high-volume SMT placement. This full suffix appears in Vishay's official ordering table (Document #88303, Page 3).
What is the maximum clamping voltage (VC) and peak pulse current (IPPM) for the 1.5SMC200CA-E3/9AT?
At a 10/1000 µs waveform, the 1.5SMC200CA-E3/9AT clamps to a maximum of 274 V when subjected to a peak pulse current (IPPM) of 5.5 A. This VC value is guaranteed under the test conditions defined in Vishay Document #88303, Table 1, and reflects worst-case behavior at TA = 25 °C with proper PCB pad layout.
Does the 1.5SMC200CA-E3/9AT meet automotive qualification standards?
The base 1.5SMC200CA-E3/9AT is RoHS-compliant commercial grade and not AEC-Q101 qualified. However, Vishay offers AEC-Q101 variants under HE3/HM3 suffixes (e.g., 1.5SMC200CAHE3_A/I). For automotive use, specify the HE3 or HM3 version - the E3/9AT variant is intended for industrial, telecom, and consumer applications per Document #88303 footnote (1).
