Product details
Overview
SM6T200CAHE3/52 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 IPPM, and 600 W peak pulse power with 10/1000 μs waveform. It features AEC-Q101 qualification, low inductance, and glass passivated junction for robust ESD and surge protection in automotive sensor signal lines.
For engineers reviewing the SM6T200CAHE3/52 datasheet, SM6T200CAHE3/52 pinout, SM6T200CAHE3/52 application, or SM6T200CAHE3/52 equivalent, key selection criteria include bidirectional clamping capability, TJ max. of 150 °C, MSL level 1 compliance, RoHS-compliant matte tin terminals, and suitability for IFSM-sensitive layouts requiring 100 A surge tolerance.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering consistent clamping performance regardless of transient polarity. Its 274 V VC at 2.2 A (10/1000 μs) ensures reliable overvoltage suppression while maintaining low leakage (<1 μA at 171 V) and thermal resistance (RθJA = 100 °C/W).
Designed for surface-mount automation, the device uses a glass-passivated silicon junction and meets J-STD-020 MSL level 1 with 260 °C reflow peak. The SMB package enables compact placement on 5.0 mm × 5.0 mm copper pads per terminal to sustain full 600 W pulse rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 171 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 190 V / 210 V - Breakdown occurs within this range at 1 mA test current, defining turn-on threshold |
| VC @ IPPM | 274 V at 2.2 A (10/1000 μs) - Clamped voltage during worst-case surge, limiting downstream stress |
| PPPM | 600 W - Peak transient energy absorption capacity under standardized 10/1000 μs waveform |
| TJ max. | +150 °C - Maximum junction temperature enabling operation in under-hood automotive environments |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient, guiding heatsinking requirements on standard PCB pads |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); cathode band absent per bidirectional design.

|---|---|
Use Scenario: Protecting LIN/CAN transceiver inputs and analog sensor outputs (e.g., pressure, temperature) from load dump and inductive switching spikes in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector or IC input pins to shunt surge energy before it reaches sensitive circuitry. Use Value: Maintains signal integrity by clamping transients to ≤274 V while surviving repeated 100 A surges per ISO 16750-2, extending system MTBF. | Use Scenario: Safeguarding differential CANH/CANL lines in factory automation controllers exposed to motor drive noise and relay switching events. IC Role / Device Role / Timing Role: Symmetrical TVS pair (one per line) suppressing common-mode and differential transients without disrupting 1 Mbps data timing. Use Value: Prevents bus lockup by limiting voltage excursions to <±300 V, ensuring uninterrupted communication during 600 W surge events. |
| Telecom Power Supply Input | Consumer Appliance Motor Control |
Use Scenario: Front-end protection of AC/DC adapter inputs in base stations and PoE injectors subjected to lightning-induced surges on primary-side traces. IC Role / Device Role / Timing Role: First-line transient absorber between fuse and bridge rectifier, diverting energy before upstream components. Use Value: Withstands 2.2 A peak pulse at 274 V clamping, reducing need for oversized input capacitors and improving surge margin per IEC 61000-4-5 Level 4. | Use Scenario: Shielding microcontroller GPIOs and gate drivers in washing machine motor inverters from commutation spikes generated by BLDC motors. IC Role / Device Role / Timing Role: Localized clamp at motor driver IC supply rails and feedback nodes to prevent latch-up or false triggering.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200CA | Same VWM (171 V) and VC (274 V), but 400 W PPPM rating and SMA package (higher RθJA = 140 °C/W) | Limited to lower-energy transients; less suitable for automotive load dump where 600 W is required | Select SMAJ200CA only if board space constraints favor smaller SMA footprint and surge energy is confirmed ≤400 W |
| 1.5KE200CA | Higher PPPM (1500 W), axial DO-201 package, higher VC (324 V), non-AEC-Q101 | Requires through-hole assembly; clamps at higher voltage, risking downstream IC damage in low-voltage systems | Choose 1.5KE200CA only for legacy through-hole designs needing higher pulse energy, not for new SMT automotive designs |
Compared with SMAJ200CA and 1.5KE200CA, SM6T200CAHE3/52 uniquely combines AEC-Q101 qualification, 600 W pulse handling in compact SMB, and precise 274 V clamping-making it optimal for space-constrained, high-reliability automotive and industrial SMT applications.

FAQ
What does the "CA" suffix indicate in SM6T200CAHE3/52?
The "CA" suffix in SM6T200CAHE3/52 denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., SM6T200A), SM6T200CAHE3/52 has no polarity marking and clamps equally in either direction-critical for protecting AC-coupled or differential signal lines such as CAN or LIN buses where transient polarity is unpredictable.
Is SM6T200CAHE3/52 suitable for automotive applications?
Yes, SM6T200CAHE3/52 is explicitly AEC-Q101 qualified (indicated by the "HE3" suffix) and rated for operation from −65 °C to +150 °C. It meets automotive surge standards including ISO 7637-2 and ISO 16750-2, with validated performance under temperature cycling, mechanical shock, and humidity testing-making SM6T200CAHE3/52 appropriate for engine control units, body electronics, and ADAS sensor modules.
What is the clamping voltage of SM6T200CAHE3/52 and how is it measured?
The clamping voltage (VC) of SM6T200CAHE3/52 is 274 V, measured at a peak pulse current (IPPM) of 2.2 A using the standardized 10/1000 μs double-exponential waveform. This value represents the maximum voltage seen across the device during a surge event and is guaranteed per Vishay's datasheet (Document Number 88385, Rev. 09-Jan-2024). Lower VC values reduce stress on downstream ICs, making SM6T200CAHE3/52 effective for protecting 200 V-rated circuits.
Does SM6T200CAHE3/52 require a heatsink for 600 W pulse handling?
No, SM6T200CAHE3/52 achieves its full 600 W peak pulse power rating without an external heatsink when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Its RθJA of 100 °C/W and low thermal mass allow rapid dissipation of transient energy. However, for sustained power dissipation (>5 W DC), additional copper area or thermal vias are advised-SM6T200CAHE3/52 is optimized for short-duration surges, not continuous operation.
How does the HE3 suffix differ from E3 or M3 in SM6T200CAHE3/52?
The "HE3" suffix in SM6T200CAHE3/52 indicates RoHS-compliant construction plus full AEC-Q101 qualification, whereas "E3" denotes RoHS-compliant commercial grade only, and "M3" adds halogen-free compliance. Only HE3- and HM3-suffixed parts undergo automotive-grade stress testing-including extended temperature life, vibration, and solderability validation-making SM6T200CAHE3/52 the correct choice for automotive Tier 1 suppliers and safety-critical subsystems.
