Product details
Overview
SM6T200CA-E3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, rated for 200 V standoff voltage (VWM), 210 V minimum breakdown voltage (VBR), 600 W peak pulse power (10/1000 μs), and clamps to 274 V at 2.2 A peak pulse current. It protects automotive sensor signal lines and industrial I/O interfaces against ESD and inductive switching transients.
For engineers reviewing the SM6T200CA-E3/5B datasheet, SM6T200CA-E3/5B pinout, SM6T200CA-E3/5B application, or SM6T200CA-E3/5B equivalent, key selection criteria include bidirectional clamping symmetry, low clamping ratio (274 V / 210 V ≈ 1.30), AEC-Q101 qualification eligibility via HE3/HM3 variants, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
The SM6T200CA-E3/5B operates as a symmetrical, silicon avalanche diode with glass-passivated junction, delivering identical electrical characteristics in both forward and reverse directions. Its bidirectional architecture eliminates polarity dependency during board-level surge events, enabling single-device protection of AC-coupled or differential signal paths.
Designed for surface-mount use in SMB (DO-214AA) package, it achieves 600 W peak pulse power handling under standardized 10/1000 μs waveform while maintaining low thermal resistance (RθJL = 20 °C/W) and meeting J-STD-020 MSL Level 1 reflow requirements (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 171 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below system rail. |
| VBR (min) | 190 V - Minimum breakdown voltage at 1 mA test current; ensures reliable conduction onset during overvoltage events. |
| VC @ IPPM | 274 V at 2.2 A - Clamping voltage under 10/1000 μs surge; determines maximum stress imposed on protected IC. |
| PPPM | 600 W - Peak pulse power dissipation capability; supports robust protection against IEC 61000-4-5 Level 4 surges. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height; compatible with JEDEC MS-012. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200CA | 400 W PPPM rating; SMA package (smaller footprint, higher RθJA = 150 °C/W); same VWM/VBR range | Limited to lower-energy transients; less suitable for IEC 61000-4-5 Level 4 due to reduced power handling | Select when board space is constrained and surge threat level is ≤ Level 3 per IEC 61000-4-5. |
| SMCJ200CA | 1500 W PPPM rating; SMC package (larger footprint, lower RθJA = 50 °C/W); identical VWM/VBR specs | Overqualified for cost-sensitive consumer designs; requires larger PCB pad area and higher assembly cost | Select when protecting high-reliability industrial power supplies where 1500 W surge margin is mandated. |
Compared with SMAJ200CA and SMCJ200CA, the SM6T200CA-E3/5B delivers optimal balance of 600 W surge capacity, SMB footprint compatibility, and automotive-grade process control-making it ideal for space-constrained, medium-energy protection in automotive and industrial edge nodes.

FAQ
What is the clamping voltage of the SM6T200CA-E3/5B under a 10/1000 μs surge?
The SM6T200CA-E3/5B clamps to 274 V at 2.2 A peak pulse current under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88385 and reflects the maximum voltage seen by downstream circuitry during surge events. The clamping ratio (VC/VBR ≈ 1.30) confirms tight regulation essential for protecting sensitive 3.3 V or 5 V logic interfaces.
Is the SM6T200CA-E3/5B suitable for automotive applications?
Yes-the SM6T200CA-E3/5B is RoHS-compliant and manufactured using the same process as AEC-Q101 qualified variants (e.g., SM6T200CAHE3_B). While the -E3/5B suffix denotes commercial grade, its construction-including glass-passivated junction, MSL Level 1 rating, and 150 °C TJ max-fully supports automotive under-hood and cabin module deployments when validated per customer qualification protocols.
How does the bidirectional design of SM6T200CA-E3/5B affect PCB layout?
The SM6T200CA-E3/5B has no polarity marking and identical electrical behavior in both directions, simplifying PCB layout by eliminating orientation constraints. Engineers can place it across any two nodes subject to bidirectional transients-such as differential pairs or AC-coupled lines-without verifying anode/cathode alignment. This reduces assembly errors and supports automated optical inspection.
What is the thermal resistance of SM6T200CA-E3/5B from junction to lead?
The SM6T200CA-E3/5B has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, as specified in the Thermal Characteristics table of Vishay document 88385. This low value enables efficient heat transfer to PCB copper pads, supporting sustained 5.0 W power dissipation at TA = 50 °C when mounted on recommended 5.0 mm × 5.0 mm pads per terminal.
Does SM6T200CA-E3/5B meet industry surge immunity standards?
Yes-the SM6T200CA-E3/5B's 600 W peak pulse power rating under 10/1000 μs waveform aligns with IEC 61000-4-5 Ed. 3 (2014) Level 4 surge testing requirements. Its clamping performance, low leakage (<1 μA at 171 V), and robust junction design make it suitable for protecting circuits subjected to 4 kV line-to-earth and 2 kV line-to-line surges in industrial and automotive systems.
