Product details
Overview
TPSMP11HM3/85A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability overvoltage protection of signal lines and ICs. It features a 9.9 V minimum breakdown voltage (VBR), 16.2 V maximum clamping voltage (VC) at 10 A peak pulse current, 185 °C junction temperature rating, and AEC-Q101 qualification for automotive use.
For engineers reviewing the TPSMP11HM3/85A datasheet, TPSMP11HM3/85A pinout, TPSMP11HM3/85A application, or TPSMP11HM3/85A equivalent, key selection criteria include unidirectional clamping performance, low-profile 1.0 mm height, MSL Level 1 solderability, and compatibility with automated SMT placement on consumer, industrial, and automotive PCBs.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to deliver fast response time (<1 ns) and low incremental surge resistance. Its unidirectional architecture provides robust forward conduction capability (IFSM = 40 A) while maintaining tight reverse leakage (≤2.0 μA at VWM = 8.92 V) across -65 °C to +185 °C operating range.
The device operates with a 8.92 V stand-off voltage (VWM) and achieves 18.5 A peak pulse current (IPPM) under 10/1000 μs waveform, delivering 300 W peak pulse power (PPPM) - optimized for protecting sensitive electronics against ESD, lightning-induced surges, and inductive switching transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.9 V / 12.1 V - ensures reliable triggering above normal operating voltage while avoiding false clamping |
| VWM | 8.92 V - maximum continuous reverse voltage before significant leakage begins |
| VC @ IPPM | 16.2 V @ 10 A - clamping voltage limits downstream component stress during surge events |
| PPPM | 300 W - peak power handling capacity for 10/1000 μs transients per JEDEC standards |
| IFSM | 40 A - surge current tolerance for 10 ms half-sine wave, supporting motor drive and relay coil protection |
| TJ max | +185 °C - enables operation in under-hood automotive environments and high-power industrial enclosures |
| Package | DO-220AA (SMP) - 1.0 mm profile supports ultra-thin designs and automated pick-and-place |
Pinout & Package
TPSMP11HM3/85A is a two-terminal unidirectional TVS diode in DO-220AA (SMP) surface-mount package. The cathode is marked by a color band on the body; polarity must be observed during PCB layout to ensure correct surge path direction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to protected line or ground return path depending on circuit topology |
| Cathode | Surge current sink terminal | Connected to system ground or reference plane to shunt transient energy away from ICs |

Use Value: Tight 9.9–12.1 V VBR window ensures clamping only during faults, not during normal rail fluctuations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Higher VC (18.2 V @ 10 A), same DO-214AC package but 2.2 mm height | Larger footprint and taller profile limit use in space-constrained automotive modules | Select when legacy SMA footprint compatibility is required and 1.0 mm height is not critical |
| TPSMP10AHM3/85A | Lower VBR (9.5–10.5 V), identical DO-220AA package and thermal specs | Better suited for 9 V nominal systems where tighter clamping margin is needed | Choose for 9 V rail protection where lower trigger threshold improves fault detection sensitivity |
Compared with SMAJ10A and TPSMP10AHM3/85A, the TPSMP11HM3/85A offers optimal balance of low-profile packaging, precise 9.9–12.1 V breakdown range, and automotive-grade reliability-making it preferred for next-generation compact, high-temperature PCB layouts requiring AEC-Q101 validation.

FAQ
What is the breakdown voltage range of the TPSMP11HM3/85A?
The TPSMP11HM3/85A has a specified breakdown voltage (VBR) range of 9.9 V minimum to 12.1 V maximum at 1 mA test current. This range ensures consistent triggering behavior across production lots and temperature extremes, enabling reliable overvoltage protection for 9 V–12 V nominal circuits without premature conduction during normal operation.
Is the TPSMP11HM3/85A suitable for automotive applications?
Yes, the TPSMP11HM3/85A is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and infotainment applications. Its DO-220AA package meets MSL Level 1, and its halogen-free, RoHS-compliant construction satisfies automotive material compliance requirements per Vishay document 99912.
What is the clamping voltage of the TPSMP11HM3/85A at 10 A peak pulse current?
The TPSMP11HM3/85A exhibits a maximum clamping voltage (VC) of 16.2 V at 10 A peak pulse current under 10/1000 μs waveform conditions. This value defines the upper voltage limit imposed on protected circuitry during surge events and is critical for ensuring downstream ICs remain within absolute maximum ratings.
Does the TPSMP11HM3/85A have a bidirectional configuration?
No, the TPSMP11HM3/85A is strictly unidirectional. Its datasheet explicitly states "Uni-direction only" under FEATURES, and electrical characteristics list only reverse-biased parameters (VBR, VWM, IR). For bidirectional protection, engineers must select a designated dual-diode configuration such as the TPSMD11H series.
What is the package type and dimensions of the TPSMP11HM3/85A?
The TPSMP11HM3/85A uses the DO-220AA (SMP) package, measuring 3.61 mm × 2.18 mm × 1.0 mm (L × W × H) with a cathode band marking. Its 1.0 mm typical height enables ultra-low-profile PCB designs, and the matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 for reliable solder joint formation.
