Product details
Overview
SM6T200CAHE3_A/H 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 clamping voltage (VC) at 2.2 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs). It provides robust ESD and surge protection for automotive sensor signal lines, power rails, and I/O interfaces.
For engineers reviewing the SM6T200CAHE3_A/H datasheet, SM6T200CAHE3_A/H pinout, SM6T200CAHE3_A/H application, or SM6T200CAHE3_A/H equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, low clamping ratio (VC/VWM ≈ 1.37), thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
The SM6T200CAHE3_A/H employs a glass-passivated silicon junction optimized for fast response (<1 ns) to transients and stable breakdown characteristics across temperature. Its bidirectional architecture enables symmetrical clamping without polarity sensitivity, supporting protection of AC-coupled or differential signal paths.
Designed per J-STD-020 MSL Level 1 (260 °C peak reflow), it delivers 600 W pulse power handling with derating above 25 °C ambient, and operates over -65 °C to +150 °C junction temperature range - meeting requirements for under-hood automotive electronics and industrial control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 200 V - maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 24 V/48 V automotive systems. |
| VBR min/max | 209 V / 231 V at 1 mA - verified breakdown threshold ensures predictable turn-on during surges. |
| VC @ IPPM | 274 V at 2.2 A (10/1000 μs) - clamping voltage limits downstream IC stress during ISO 7637-2 Pulse 1/2a/5a events. |
| PPPM | 600 W - peak transient energy absorption capability compatible with IEC 61000-4-5 Level 4 (4 kV line-to-line). |
| RθJA | 100 °C/W - thermal resistance determines junction temperature rise under sustained power dissipation; requires minimum 5.0 mm × 5.0 mm copper pads. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including HTOL, TC, UHAST, and ESD HBM ≥ 8 kV. |
| Package | SMB (DO-214AA) - surface-mount outline with 2.20 mm max height; supports high-density PCB layout and automated pick-and-place. |
Pinout & Package
Package: SMB (DO-214AA), bidirectional device with no polarity marking; terminals are matte tin-plated, solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point (either direction) | Accepts surge current from either terminal due to symmetrical bidirectional structure; no cathode band marking. |
| Cathode | Transient current exit point (either direction) | Completes conduction path during clamping; functionally identical to Anode in CA-suffix devices. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., CAN, LIN), and ungrounded power rails without polarity concerns. |
| 600 W peak pulse power (10/1000 μs) | Withstands repetitive load-dump transients per ISO 7637-2 and lightning-induced surges per IEC 61000-4-5 up to 4 kV. |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, ADAS sensors, and body electronics requiring long-term field reliability. |
| Low inductance SMB package | Minimizes voltage overshoot during fast-rising transients (<1 ns response), critical for protecting high-speed digital interfaces. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow profile (peak 260 °C), eliminating bake-out requirements in production. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200A-E3/5B | Unidirectional; VWM = 200 V, VC = 324 V at 1.85 A; lower PPPM (400 W); non-AEC-Q101. | Limited to DC-biased rails where polarity is fixed; unsuitable for AC or differential signal protection. | Select when cost sensitivity outweighs automotive qualification and bidirectional capability. |
| 1.5KE200CA | Through-hole DO-201 package; same VWM/VC specs but larger footprint; higher RθJA (60 °C/W on infinite heatsink only). | Requires manual or wave soldering; incompatible with high-density SMT production; better for prototyping or legacy designs. | Choose only if existing PCB layout prohibits SMB replacement or thermal design accommodates through-hole mounting. |
Compared with SMAJ200A-E3/5B and 1.5KE200CA, the SM6T200CAHE3_A/H uniquely combines AEC-Q101 qualification, bidirectional operation, SMB packaging, and 600 W pulse rating - making it the only option qualified for volume automotive SMT production with symmetrical clamping needs.

FAQ
What is the clamping voltage of SM6T200CAHE3_A/H under standard test conditions?
The SM6T200CAHE3_A/H has a maximum clamping voltage (VC) of 274 V when subjected to a 10/1000 μs waveform at 2.2 A peak pulse current (IPPM), measured per JEDEC standards. This value is confirmed in the Vishay datasheet revision 09-Jan-2024, Document Number 88385, and defines the upper voltage limit imposed on protected circuitry during surge events. The SM6T200CAHE3_A/H maintains this clamping performance across its specified operating temperature range.
Is SM6T200CAHE3_A/H suitable for automotive applications?
Yes, SM6T200CAHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use with ordering code suffix "HE3". It undergoes stress testing including high-temperature operating life (HTOL), temperature cycling, and ESD (HBM ≥ 8 kV), meeting requirements for engine control, ADAS sensors, and body electronics. The SM6T200CAHE3_A/H is listed in Vishay's automotive-grade product portfolio with full traceability and PPAP support.
What does the "CA" suffix indicate in SM6T200CAHE3_A/H?
The "CA" suffix in SM6T200CAHE3_A/H denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression in both polarities - unlike unidirectional "A" variants. This allows protection of AC-coupled signals, differential buses (e.g., CAN, RS-485), or floating power domains without regard to polarity. The SM6T200CAHE3_A/H exhibits identical VBR, VC, and PPPM specifications in either direction.
What is the thermal resistance of SM6T200CAHE3_A/H, and how does it affect PCB layout?
The SM6T200CAHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe junction temperatures under repeated surge conditions, PCB layout must provide these minimum pad dimensions and avoid excessive thermal isolation. The SM6T200CAHE3_A/H datasheet specifies that derating begins above TA = 25 °C using Figure 2.
How does SM6T200CAHE3_A/H compare to unidirectional TVS diodes with the same VWM?
Compared to unidirectional equivalents like SM6T200AHE3_A/H, the SM6T200CAHE3_A/H offers identical VWM (200 V), VBR (209–231 V), and PPPM (600 W), but enables protection of bidirectional signal paths without polarity constraints. Its clamping voltage remains symmetric, whereas unidirectional devices conduct only in reverse bias - making the SM6T200CAHE3_A/H essential for AC, differential, or unknown-polarity applications.
