Product details
Overview
SM6T200AHE3_B/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, rated for 200 V standoff voltage (VWM = 171 V), 210 V minimum breakdown (VBR), 274 V maximum clamping voltage at 2.2 A IPPM, 600 W peak pulse power (10/1000 μs), and AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the SM6T200AHE3_B/H datasheet, SM6T200AHE3_B/H pinout, SM6T200AHE3_B/H application, or SM6T200AHE3_B/H equivalent, key selection criteria include clamping performance under 10/1000 μs surge, unidirectional polarity with cathode band marking, RoHS-compliant matte tin terminals, and MSL Level 1 reflow compatibility up to 260 °C.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging a glass-passivated silicon junction to limit transient overvoltages on power or signal lines. Its 274 V clamping voltage at 2.2 A (10/1000 μs) ensures robust protection of downstream ICs and MOSFETs against inductive switching spikes and ESD events.
Designed for surface-mount automated placement, it features low inductance and thermal resistance (RθJA = 100 °C/W, RθJL = 20 °C/W), enabling effective energy dissipation during repetitive or single-pulse transients while maintaining junction temperature ≤150 °C under specified mounting conditions.

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V battery-fed ECUs and body control modules from ISO 7637-2 load dump and jump-start surges. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and input filter capacitor to clamp transients before LDO or DC-DC regulator.

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 | Same VWM (171 V), VBR (190–210 V), VC (274 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA) | Less suitable for high-energy automotive load dump; preferred where board space is constrained and surge energy is lower | Select SMAJ200A-E3/5B only if peak transient energy remains ≤400 W and thermal budget allows higher junction temperature rise |
| SMCJ200AHE3_A/H | Same electrical specs but SMC (DO-214AB) package: larger footprint, lower RθJA (50 °C/W), higher IFSM (200 A) | Better suited for systems requiring higher surge repetition rate or extended thermal margin in high-ambient environments | Choose SMCJ200AHE3_A/H when PCB layout permits larger pad area and sustained surge duty cycle exceeds SM6T200AHE3_B/H derating limits |
Compared with SMAJ200A-E3/5B, SM6T200AHE3_B/H delivers 50 % higher pulse power handling in the same general SMB form factor; versus SMCJ200AHE3_A/H, it trades thermal robustness and surge current capacity for smaller board area and lower assembly cost-making it optimal for space-constrained automotive modules where 600 W single-event suppression suffices.

FAQ
What is the clamping voltage of SM6T200AHE3_B/H at its rated peak pulse current?
The SM6T200AHE3_B/H has a maximum clamping voltage (VC) of 274 V when subjected to its rated peak pulse current of 2.2 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88385 and defines the upper voltage limit imposed on the protected circuit during transient events. The clamping performance is guaranteed across the full operating temperature range and is critical for ensuring downstream components remain within their absolute maximum voltage ratings. SM6T200AHE3_B/H maintains this clamping behavior consistently due to its glass-passivated junction and controlled avalanche characteristics.
Is SM6T200AHE3_B/H suitable for automotive applications?
Yes, SM6T200AHE3_B/H is AEC-Q101 qualified and explicitly designated for automotive use, as confirmed by its "HE3" suffix and documentation in Vishay's SM6T series datasheet. It meets requirements for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life relevant to under-hood and cabin-mounted ECUs. The device is rated for junction temperatures up to +150 °C and supports reflow profiles up to 260 °C (MSL Level 1), making it appropriate for modern automotive power distribution and sensor interface designs. SM6T200AHE3_B/H is commonly deployed in battery management, lighting control, and body electronics modules.
What does the "HE3_B/H" suffix indicate in SM6T200AHE3_B/H?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification; "B/H" specifies packaging: "B" indicates tape-and-reel format per EIA-481, and "H" identifies the 7-inch reel size containing 750 units. This ordering code aligns with Vishay's standardized nomenclature in Document Number 88385, where "H" corresponds to the preferred package code for 7″ reels. SM6T200AHE3_B/H is not a variant with altered electrical specs-it retains identical VWM, VBR, VC, and PPPM ratings as the base SM6T200A, differing only in compliance status and packaging configuration.
How does the SMB package of SM6T200AHE3_B/H compare thermally to larger packages like SMC?
The SMB (DO-214AA) package of SM6T200AHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W, significantly higher than the ~50 °C/W of the SMC (DO-214AB) package used in equivalents like SMCJ200AHE3_A/H. This means SM6T200AHE3_B/H requires careful PCB layout-minimum 0.2″ × 0.2″ copper pads per terminal-to achieve rated power dissipation. Under high ambient temperatures or repetitive surge conditions, its junction temperature rise will be greater than that of SMC-packaged devices. SM6T200AHE3_B/H is optimized for single-event or low-duty-cycle transients where board space constraints outweigh thermal margin needs.
Can SM6T200AHE3_B/H be used in bidirectional configurations?
No, SM6T200AHE3_B/H is a unidirectional TVS diode, as indicated by its part number ending in "A" (not "CA") and explicit designation in the Vishay SM6T datasheet. Bidirectional variants require the "CA" suffix (e.g., SM6T200CA) and exhibit symmetrical breakdown in both polarities. Using SM6T200AHE3_B/H in a bidirectional application would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit. For bidirectional protection, select SM6T200CAHE3_B/H or equivalent-SM6T200AHE3_B/H must be installed with correct cathode orientation relative to the protected line's polarity.
