Product details
Overview
SM6T220AHE3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, rated for 220 V breakdown voltage (VBR), 328 V maximum clamping voltage (VC) at 2.0 A peak pulse current, and 600 W peak pulse power with 10/1000 μs waveform. It provides robust overvoltage protection for automotive-grade power rails and sensor interfaces.
For engineers reviewing the SM6T220AHE3_A/H datasheet, SM6T220AHE3_A/H pinout, SM6T220AHE3_A/H application, or SM6T220AHE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, 188 V stand-off voltage (VWM), 1.0 μA max reverse leakage at VWM, 150 °C max junction temperature, and low-inductance SMB package optimized for high-speed transient suppression in harsh environments.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging a glass-passivated silicon junction to deliver fast response (<1 ns) to ESD and surge events. Its electrical behavior is defined by precise VBR (209–231 V), VC (328 V @ 2.0 A, 10/1000 μs), and thermal resistance (RθJA = 100 °C/W).
Designed for surface-mount assembly on standard PCB copper pads (0.2" × 0.2"), it meets J-STD-020 MSL Level 1 and supports reflow up to 260 °C peak. The cathode band identifies polarity, and its low inductance minimizes voltage overshoot during fast transients.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ220A | Same VBR range (209–231 V), but lower PPPM (400 W), SMA package (higher RθJA = 140 °C/W) | Limited to lower-energy transients; unsuitable for automotive load dump per ISO 7637-2 | Select when cost sensitivity outweighs surge margin and board space allows larger pad layout |
| 1.5SMC220A | Higher PPPM (1500 W), DO-214AB package (larger footprint), same VBR/VC specs | Better thermal handling for repeated surges; requires revised PCB land pattern | Choose for industrial systems requiring >1000 surge cycles without parameter drift |
Compared with SMAJ220A and 1.5SMC220A, SM6T220AHE3_A/H delivers optimal balance of AEC-Q101 compliance, SMB footprint efficiency, and 600 W surge capacity-making it preferred for space-constrained automotive modules where qualification and reliability are mandatory.

FAQ
What is the clamping voltage of SM6T220AHE3_A/H at its rated peak pulse current?
The SM6T220AHE3_A/H has a maximum clamping voltage (VC) of 328 V when subjected to a 2.0 A peak pulse current with a 10/1000 μs waveform. This value is measured under standardized test conditions per JEDEC standards and ensures predictable overvoltage limiting for downstream components in the protected circuit. The clamping performance is guaranteed across the full operating temperature range of −65 °C to +150 °C.
Is SM6T220AHE3_A/H qualified for automotive applications?
Yes, SM6T220AHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in datasheet 88385. This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD, making SM6T220AHE3_A/H suitable for use in automotive powertrain, body control, and ADAS modules where reliability under thermal and electrical stress is critical.
What is the standoff voltage rating for SM6T220AHE3_A/H?
The standoff voltage (VWM) for SM6T220AHE3_A/H is 188 V, meaning it remains non-conductive with reverse leakage ≤1.0 μA up to this DC or RMS voltage. This rating allows integration into 180–200 V nominal systems such as 48 V mild-hybrid architectures or industrial 200 V DC bus lines, ensuring stable operation without premature conduction during normal operation.
Does SM6T220AHE3_A/H have a bidirectional variant?
No, SM6T220AHE3_A/H is unidirectional only. Bidirectional variants in the SM6T family use the "CA" suffix (e.g., SM6T220CA). The "A" suffix in SM6T220AHE3_A/H denotes unidirectional configuration, with polarity indicated by the cathode band. For bidirectional protection needs, SM6T220CAHE3_A/H must be selected separately and verified for matching VBR and VC specifications.
What package type does SM6T220AHE3_A/H use, and what are its mounting requirements?
SM6T220AHE3_A/H uses the SMB (DO-214AA) surface-mount package with matte tin-plated leads. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for thermal and mechanical reliability. It complies with J-STD-020 MSL Level 1 and supports lead-free reflow up to 260 °C peak temperature, with no pre-bake required.
