Product details
Overview
TPSMC11AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features 11.0 V nominal breakdown voltage (VBR), 9.40 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 15.6 V maximum clamping voltage at 96.2 A, and operates up to +185 °C junction temperature - used in automotive power rail protection and industrial sensor interface circuits.
For engineers reviewing the TPSMC11AHE3_B/I datasheet, TPSMC11AHE3_B/I pinout, TPSMC11AHE3_B/I application, or TPSMC11AHE3_B/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, MSL Level 1 rating, 10 µA max reverse leakage at VWM, and compatibility with high-reliability PCB layouts requiring robust surge immunity per IEC 61000-4-5.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping performance under repetitive surge stress. Its 185 °C maximum junction temperature enables operation in under-hood automotive environments and high-temperature industrial enclosures without derating penalties.
The device responds in sub-nanosecond time to transient events and maintains low incremental surge resistance during 10/1000 µs surges up to 96.2 A. Its cathode-band polarity marking and matte tin-plated leads ensure reliable solderability per J-STD-002 and whisker resistance per JESD 201 Class 2.
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 |
|---|---|---|---|
| SMBJ11A | Lower PPPM (600 W), same VBR and package (SMB/DO-214AA), non-AEC-Q101 | Not qualified for automotive under-hood use; suitable for cost-sensitive consumer power supplies | Select when surge energy is limited to ≤600 W and AEC-Q101 is not required |
| TPSMC11AHM3_B/I | Identical electrical specs; halogen-free molding compound and JESD 201 Class 2 whisker rating - same AEC-Q101 qualification | No functional difference; chosen only when halogen-free compliance is mandated by OEM material declarations | Select when RoHS + halogen-free + AEC-Q101 must all be satisfied simultaneously |
Compared with SMBJ11A and TPSMC11AHM3_B/I, the TPSMC11AHE3_B/I offers the highest surge robustness (1500 W) among SMC-packaged 11 V TVS diodes with full automotive qualification, making it optimal for safety-critical power rail protection where both energy handling and reliability are non-negotiable.

FAQ
What is the clamping voltage of the TPSMC11AHE3_B/I at its rated peak pulse current?
The TPSMC11AHE3_B/I has a maximum clamping voltage (VC) of 15.6 V when subjected to its peak pulse current (IPPM) of 96.2 A under the standard 10/1000 µs waveform. This value is measured per test condition defined in the Vishay datasheet (Document Number: 88407) and reflects worst-case clamping performance at TA = 25 °C. The TPSMC11AHE3_B/I maintains this clamping behavior across its full operating temperature range due to its low VBR temperature coefficient of 0.067 %/°C.
Is the TPSMC11AHE3_B/I qualified for automotive applications?
Yes, the TPSMC11AHE3_B/I is AEC-Q101 qualified, as confirmed by Vishay's documentation and indicated by the "HE3" suffix in its ordering code. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD, validating its suitability for automotive powertrain, chassis, and body electronics. The TPSMC11AHE3_B/I is rated for continuous operation up to +185 °C junction temperature, supporting under-hood deployment without derating.
What does the "B/I" suffix mean in TPSMC11AHE3_B/I?
The "B/I" suffix in TPSMC11AHE3_B/I denotes the revision level ("B") and packaging format ("I"). "I" specifies bulk packaging in 13-inch diameter plastic tape and reel, containing 3500 units per reel. This differs from the "H" variant (e.g., TPSMC11AHE3_B/H), which uses 7-inch reels with 850 units. Both share identical electrical and thermal specifications; only mechanical packaging and quantity differ.
What is the maximum reverse leakage current of the TPSMC11AHE3_B/I at its stand-off voltage?
The TPSMC11AHE3_B/I exhibits a maximum reverse leakage current (IR) of 5.0 µA at its stand-off voltage (VWM) of 9.40 V and ambient temperature of 25 °C. At elevated temperatures (e.g., 150 °C), leakage increases to 50 µA - still within specification limits. This low leakage ensures minimal power loss in always-on automotive modules and preserves accuracy in precision sensor signal chains where TPSMC11AHE3_B/I is deployed.
Does the TPSMC11AHE3_B/I have a unidirectional or bidirectional configuration?
The TPSMC11AHE3_B/I is a unidirectional TVS diode, as explicitly stated in the Vishay datasheet. It functions as a single-polarity clamp - conducting only when cathode voltage exceeds anode voltage by more than VBR. This makes it ideal for DC power rail and single-ended signal line protection. Bidirectional variants (e.g., TPSMC11CA) exist in the same family but are distinct part numbers; the TPSMC11AHE3_B/I is not interchangeable with them without circuit redesign.
