Product details
Overview
SM6T220CAHE3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 220 V breakdown voltage (VBR = 209–231 V), 600 W peak pulse power (10/1000 μs), 328 V maximum clamping voltage at IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SM6T220CAHE3/5B datasheet, SM6T220CAHE3/5B pinout, SM6T220CAHE3/5B application, or SM6T220CAHE3/5B equivalent, key selection criteria include bidirectional clamping capability, low-inductance SMB footprint, automotive-grade reliability, and compatibility with 10/1000 μs surge waveforms per IEC 61000-4-5.
Technical Context
The SM6T220CAHE3/5B operates as a bidirectional avalanche diode, symmetrically clamping both positive and negative transients without polarity dependence. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1.0 μA at 188 V), while the low-inductance SMB package supports fast response to sub-microsecond ESD and lightning-induced surges.
Thermally, it sustains 150 °C maximum junction temperature with RθJA = 100 °C/W (on 0.2" × 0.2" copper pads) and handles non-repetitive peak pulse currents up to 2.0 A (10/1000 μs) at VC = 328 V. It meets MSL Level 1 and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 209 V / 231 V - Ensures reliable triggering above 188 V stand-off; ±5% tolerance enables predictable clamping onset. |
| VWM | 188 V - Maximum continuous reverse operating voltage; defines safe DC/AC bias margin before leakage rises. |
| VC @ IPPM | 328 V - Clamped voltage during 600 W 10/1000 μs surge; limits downstream IC stress to <330 V. |
| PPPM | 600 W - Peak surge power handling per IEC 61000-4-5; validates robustness against lightning and inductive switching. |
| IPPM | 2.0 A - Peak pulse current corresponding to VC = 328 V; determines minimum trace width and PCB layout clearance. |
| TJmax | 150 °C - Maximum junction temperature; supports under-hood automotive operation with derating above 25 °C. |
| AEC-Q101 | Qualified - Confirmed reliability for automotive electronics per stress test standard; required for ECUs and ADAS sensors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA | Same VBR range (209–231 V), identical SMB package, but rated for 600 W with lower VC = 324 V; not AEC-Q101 qualified. | Lacks automotive qualification; suitable for industrial/commercial designs where AEC-Q101 is not mandated. | Select SMBJ220CA when cost optimization is prioritized and automotive reliability certification is unnecessary. |
| 1.5KE220CA | Higher PPPM = 1500 W, DO-201 package (larger), VC = 356 V; leaded through-hole, not SMT-compatible. | Requires PCB through-hole mounting and larger board area; unsuitable for space-constrained automotive modules. | Choose 1.5KE220CA only if higher surge rating is mandatory and SMT assembly is not required. |
Compared with SMBJ220CA and 1.5KE220CA, SM6T220CAHE3/5B uniquely combines AEC-Q101 qualification, SMB footprint, and 600 W capability-making it the only drop-in solution for automotive SMT designs requiring certified reliability and minimal board space.

FAQ
What is the clamping voltage of SM6T220CAHE3/5B at its rated peak pulse current?
The SM6T220CAHE3/5B has a maximum clamping voltage (VC) of 328 V at its peak pulse current (IPPM) of 2.0 A under a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88385 and defines the upper voltage limit imposed on protected circuitry during surge events. The SM6T220CAHE3/5B maintains this clamping performance across its specified operating temperature range.
Is SM6T220CAHE3/5B suitable for automotive applications?
Yes, SM6T220CAHE3/5B is AEC-Q101 qualified, as confirmed by its HE3 suffix and documentation in Vishay's SM6T datasheet (Rev. 09-Jan-2024). It undergoes stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life-meeting requirements for engine control units, body electronics, and ADAS sensor modules. The SM6T220CAHE3/5B is explicitly designated for automotive-grade use.
What does the "CA" suffix indicate in SM6T220CAHE3/5B?
The "CA" suffix in SM6T220CAHE3/5B denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., SM6T220A), the SM6T220CAHE3/5B has no cathode/anode marking and functions identically regardless of terminal orientation-critical for AC-coupled or differential signal line protection.
What is the standoff voltage (VWM) of SM6T220CAHE3/5B?
The standoff voltage (VWM) of SM6T220CAHE3/5B is 188 V, representing the maximum continuous reverse voltage the device can withstand without significant leakage current. At this voltage, reverse leakage is guaranteed ≤1.0 μA, ensuring minimal power loss and no interference with normal circuit operation. This VWM value is directly specified in the Electrical Characteristics table of Vishay document 88385 for SM6T220CAHE3/5B.
What package type does SM6T220CAHE3/5B use, and what are its key mechanical attributes?
SM6T220CAHE3/5B uses the SMB (DO-214AA) surface-mount package, measuring 4.57 mm × 3.94 mm × 2.20 mm with matte tin-plated leads. It complies with J-STD-002 solderability and JESD22-B102 lead finish standards, supports MSL Level 1 handling, and features UL 94 V-0 flammability-rated molding compound. The SMB footprint enables automated placement and high-density PCB layouts without compromising thermal or surge performance.
