Product details
Overview
SM6T200CAHE3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, rated for 200 V standoff voltage (VWM), 274 V maximum clamping voltage (VC) at 2.2 A IPPM, and 600 W peak pulse power with 10/1000 μs waveform. It provides robust ESD and surge protection for automotive sensor signal lines, power rails, and I/O interfaces operating up to 150 °C junction temperature.
For engineers reviewing the SM6T200CAHE3/5B datasheet, SM6T200CAHE3/5B pinout, SM6T200CAHE3/5B application, or SM6T200CAHE3/5B equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, low-inductance SMB package layout compatibility, and verified 274 V clamping at 2.2 A under standardized 10/1000 μs transients.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) of 210 V min / 231 V max measured at 1 mA IT, and clamps transients within 274 V at 2.2 A peak pulse current. Its glass-passivated junction ensures stable leakage (<1 μA at VWM) and reliability under repeated surge stress.
Thermal performance is defined by RθJA = 100 °C/W and RθJL = 20 °C/W, supporting operation from –65 °C to +150 °C. The device meets MSL Level 1 per J-STD-020 and is qualified to AEC-Q101 for automotive use, with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 200 V - Maximum continuous reverse working voltage before clamping initiates; defines safe operating margin for 24 V/48 V automotive systems. |
| VBR (min/max) | 210 V / 231 V at 1 mA - Confirmed breakdown threshold in both directions; ensures symmetrical overvoltage response. |
| 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. |

| TJ max. | +150 °C - Maximum junction temperature rating enables under-hood deployment without derating in most automotive environments. |
| Package | SMB (DO-214AA) - Surface-mount outline with 2.20 mm × 3.94 mm footprint; compatible with automated pick-and-place and reflow profiles up to 260 °C peak. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per AEC-Q101 Rev D. |

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; 200 V VWM; 324 V VC @ 1.85 A; same SMB package but lacks AEC-Q101 qualification. | Requires external polarity management; not approved for automotive under-hood use. | Select only for non-automotive industrial or telecom applications where unidirectional clamping suffices and AEC-Q101 is not mandated. |
| SMCJ200CA | Bidirectional; 200 V VWM; 324 V VC @ 3.1 A; larger SMC (DO-214AB) package with higher PPPM (1500 W). | Higher clamping voltage reduces protection margin; requires larger PCB area and different thermal pad layout. | Choose when system-level surge tests exceed 600 W and board space allows SMC footprint; not drop-in compatible with SMB layout. |
Compared with SMAJ200A-E3/5B and SMCJ200CA, SM6T200CAHE3/5B uniquely delivers AEC-Q101 qualification, lower clamping voltage (274 V vs. ≥324 V), and SMB footprint compatibility-making it optimal for space-constrained automotive sensor nodes requiring certified reliability.

FAQ
What does the "CA" suffix indicate in SM6T200CAHE3/5B?
The "CA" suffix denotes a bidirectional configuration, meaning SM6T200CAHE3/5B clamps voltage transients equally in both polarities-unlike unidirectional variants ending in "A". This eliminates polarity concerns during placement and enables protection of AC-coupled or floating signal paths without external diode pairing. The CA version maintains identical VWM (200 V), VBR (210–231 V), and PPPM (600 W) ratings as its unidirectional counterpart.
Is SM6T200CAHE3/5B qualified for automotive applications?
Yes, SM6T200CAHE3/5B is AEC-Q101 qualified, as confirmed by the "HE3" suffix and Vishay documentation. It undergoes rigorous stress testing-including temperature cycling, highly accelerated life testing (HALT), and ESD validation-to meet automotive reliability standards. This qualification makes SM6T200CAHE3/5B suitable for under-hood and chassis-mounted modules where ambient temperatures reach 125 °C and transient immunity must comply with ISO 7637-2 and ISO 16750-2.
What is the maximum clamping voltage of SM6T200CAHE3/5B under standard test conditions?
The maximum clamping voltage (VC) of SM6T200CAHE3/5B is 274 V when subjected to a 10/1000 μs waveform at 2.2 A peak pulse current (IPPM), per Vishay's datasheet Figure 1 and Table on page 2. This value is measured across both terminals with the device mounted on 5.0 mm × 5.0 mm copper pads. At lower currents (e.g., 1 A), VC drops to approximately 250 V, providing tighter protection margins for sensitive downstream circuitry.
How does the SMB (DO-214AA) package of SM6T200CAHE3/5B affect PCB layout?
The SMB package of SM6T200CAHE3/5B measures 3.94 mm × 2.20 mm with 2.18 mm minimum terminal width, requiring precise pad geometry per Vishay's recommended mounting layout. Its low profile (max 1.95 mm height) and MSL Level 1 rating allow direct placement into high-density automotive PCBs without baking or special reflow profiles. Because SM6T200CAHE3/5B is bidirectional, no cathode band marking exists-eliminating orientation checks during automated assembly.
What is the junction-to-ambient thermal resistance (RθJA) of SM6T200CAHE3/5B?
The typical junction-to-ambient thermal resistance (RθJA) of SM6T200CAHE3/5B is 100 °C/W, measured under standard JEDEC conditions (single device on FR-4 board with 1 oz copper, 0.2" × 0.2" pads per terminal). This value assumes no additional heatsinking; for sustained 5.0 W power dissipation, board-level thermal design must maintain ambient temperature ≤75 °C to keep TJ ≤150 °C. RθJL is 20 °C/W, indicating efficient heat conduction to PCB copper planes.
