Product details
Overview
TPSMP11HM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability overvoltage protection of sensitive electronics. It features 9.9 V to 12.1 V breakdown voltage (VBR), 18.5 A peak pulse current (IPPM), 16.2 V clamping voltage (VC) at IPPM, 2.5 W steady-state power dissipation, and AEC-Q101 qualification for automotive use.
For engineers reviewing the TPSMP11HM3/84A datasheet, TPSMP11HM3/84A pinout, TPSMP11HM3/84A application, or TPSMP11HM3/84A equivalent, this device serves as a compact, low-profile (1.0 mm height), high-surge-capacity protector for signal lines, drive transistors, and ICs in automotive ECUs, industrial sensors, and consumer power interfaces where TJ = 185 °C operation and MSL Level 1 handling are required.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD and lightning-induced transients per IEC 61000-4-2 and ISO 16750-2. Its unidirectional configuration provides forward conduction path during overvoltage events while maintaining low leakage (≤2.0 μA at VWM = 8.92 V) under normal operation.
The device operates across -65 °C to +185 °C junction temperature range and is rated for 40 A non-repetitive forward surge current (IFSM). Its DO-220AA package supports automated placement and meets UL 94 V-0 flammability rating with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102.

Use Value: AEC-Q101 qualification ensures zero infant mortality in thermal cycling; matte tin terminations support robust solder joints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | DO-214AC package (higher profile: 2.3 mm), 11 V nominal VBR, 200 W PPPM, same 185 °C TJ | Larger footprint; less suitable for ultra-thin automotive modules or high-density sensor PCBs | Select when legacy DO-214AC layout exists and 1.0 mm height is not critical |
| TPSMP11A | Same family, tighter VBR tolerance (10.5–11.6 V vs. 9.9–12.1 V), identical DO-220AA package and ratings | No change in mechanical fit or thermal performance; improved voltage consistency for precision clamping | Choose for designs requiring tighter VBR control without altering board layout or thermal design |
Compared with SMAJ11A, TPSMP11HM3/84A offers 30 % lower profile and 50 % higher peak power in same voltage class; versus TPSMP11A, it trades ±5 % VBR tolerance for broader availability and cost efficiency in non-critical clamping applications.

FAQ
What is the breakdown voltage range of the TPSMP11HM3/84A?
The TPSMP11HM3/84A has a specified breakdown voltage (VBR) range of 9.9 V minimum to 12.1 V maximum at 1.0 mA test current. This range reflects the standard tolerance for the non-"A" variant in the TPSMP11 family and ensures reliable turn-on behavior across manufacturing lots while maintaining compatibility with 12 V system rails.
Is the TPSMP11HM3/84A suitable for automotive applications?
Yes, the TPSMP11HM3/84A is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and cabin automotive applications including body control modules, infotainment power supplies, and ADAS camera interfaces. Its DO-220AA package also meets MSL Level 1 for robust reflow processing.
What is the clamping voltage of the TPSMP11HM3/84A at its rated peak pulse current?
The TPSMP11HM3/84A exhibits a maximum clamping voltage (VC) of 16.2 V at its rated peak pulse current (IPPM) of 18.5 A under 10/1000 μs waveform conditions. This value ensures protected downstream ICs see limited overvoltage stress during surge events while maintaining safe margin below typical 18 V absolute maximum ratings.
Does the TPSMP11HM3/84A have a bidirectional configuration?
No, the TPSMP11HM3/84A is a unidirectional TVS diode only. Its electrical structure supports clamping of positive transients relative to ground and does not provide symmetric protection for negative excursions. For bidirectional protection, a separate part such as TPSMP11AHM3/84A (if available) or a dedicated bidirectional TVS must be selected.
What package type does the TPSMP11HM3/84A use, and what are its key mechanical attributes?
The TPSMP11HM3/84A uses the DO-220AA (SMP) surface-mount package, measuring 3.61 mm × 1.88 mm × 1.0 mm (L × W × H). It features matte tin-plated leads compliant with J-STD-002, a cathode identification band, UL 94 V-0 molding compound, and is optimized for high-speed automated placement with minimal tombstoning risk.
