Product details
Overview
TPSMP10HM3/85A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability overvoltage protection of sensitive electronics. It features a 9.0–11.0 V breakdown voltage (VBR), 15.0 V clamping voltage (VC) at 20.0 A peak pulse current, 200 W peak pulse power rating, and operates up to +185 °C junction temperature-ideal for automotive power line and sensor interface protection.
For engineers reviewing the TPSMP10HM3/85A datasheet, TPSMP10HM3/85A pinout, TPSMP10HM3/85A application, or TPSMP10HM3/85A equivalent, this device delivers low-profile (1.0 mm height), AEC-Q101 qualified surge suppression with MSL Level 1 reflow compatibility and halogen-free, RoHS-compliant construction-critical for automated SMT assembly in harsh-environment automotive ECUs and industrial controllers.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve fast response time (<1 ns) and low incremental surge resistance, enabling effective clamping of ESD and lightning-induced transients per IEC 61000-4-2 and ISO 7637-2. Its unidirectional configuration supports DC-biased signal and power lines where reverse conduction must be blocked.
The device is rated for 40 A non-repetitive forward surge current (IFSM) and dissipates 2.5 W under steady-state conditions on infinite heatsink at 75 °C ambient. Thermal design leverages its 185 °C maximum junction temperature and low thermal resistance enabled by the DO-220AA package's copper lead frame and optimized PCB pad layout (5.0 mm × 5.0 mm per terminal).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.0 V / 11.0 V - ensures reliable triggering above normal 8.5 V system operating voltage while avoiding false trips |
| VC @ IPPM | 15.0 V at 20.0 A - limits downstream IC voltage stress during 10/1000 μs transients |
| PPPM | 200 W - sustains high-energy surges typical in 12 V automotive load-dump events |
| IFSM | 40 A - withstands repetitive motor-commutation spikes without degradation |
| TJ max | +185 °C - supports under-hood placement in automotive modules without derating |
| VWM | 8.10 V - provides 0.5 V margin below nominal 8.5 V rail, ensuring no leakage during normal operation |
| Package | DO-220AA (SMP) - 1.0 mm profile enables compact layout in space-constrained modules |
Pinout & Package
DO-220AA (SMP) surface-mount package with matte tin-plated leads; cathode denoted by color band; compliant with J-STD-002 and JESD 22-B102 solderability standards; meets MSL Level 1 (260 °C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply inputs in engine control units (ECUs) against load dump and jump-start transients per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between battery rail and input filter capacitor. Use Value: Clamps transients to ≤15.0 V, preventing damage to upstream PMICs and microcontrollers rated for 16 V absolute maximum. | Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loop drivers) in factory automation sensors exposed to cable ESD and inductive switching noise. IC Role / Device Role / Timing Role: Line-to-ground TVS on transmitter output, positioned before connector interface. Use Value: Sub-1 ns response limits voltage excursion to <18 V during ±8 kV contact ESD (IEC 61000-4-2), preserving ADC reference integrity. |
| Consumer USB Power Port Protection | Telecom DC Feeder Protection |
Use Scenario: Overvoltage suppression on 5 V USB Type-C VBUS lines in portable docking stations subjected to hot-plug and adapter fault conditions. IC Role / Device Role / Timing Role: Unidirectional TVS between VBUS and GND, adjacent to USB controller port. Use Value: 200 W peak power rating absorbs 10/1000 μs surges up to 20 A without failure, maintaining USB PD handshake reliability. | Use Scenario: Protecting -48 V DC power feeds in remote radio head (RRH) base station equipment from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Reverse-polarity TVS (cathode to -48 V rail, anode to GND) for negative-rail clamping. Use Value: 185 °C rating ensures stable operation in sealed outdoor enclosures with ambient temperatures up to +85 °C. |
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 | DO-214AC package (2.79 mm height), 200 W PPPM, VC = 16.0 V @ 17.1 A, TJ max = +150 °C | Higher profile limits use in ultra-thin modules; lower temperature rating restricts under-hood deployment | Select when legacy DO-214AC footprint is fixed and 150 °C operation suffices |
| TPSMA6.8A | Same DO-220AA package, but lower VBR (6.45–7.14 V), VC = 10.5 V @ 500 A, PPPM = 300 W | Better suited for 5 V rail protection; not rated for 12 V automotive systems due to insufficient VWM margin | Select for 5 V logic line protection where tighter clamping and higher surge capacity are required |
Compared with SMAJ10A and TPSMA6.8A, the TPSMP10HM3/85A offers superior thermal capability (+185 °C vs. +150 °C) and lower profile (1.0 mm vs. 2.79 mm), making it optimal for next-generation automotive modules requiring both space savings and extended temperature operation-while TPSMA6.8A serves lower-voltage rails and SMAJ10A suits legacy board designs.

FAQ
What is the breakdown voltage range for TPSMP10HM3/85A?
The TPSMP10HM3/85A has a specified breakdown voltage (VBR) range of 9.0 V minimum to 11.0 V maximum at 1.0 mA test current. This ensures consistent turn-on behavior across production lots while providing sufficient margin above typical 8.5 V nominal 12 V system rails to prevent nuisance conduction during normal operation.
Is TPSMP10HM3/85A suitable for automotive applications?
Yes, the TPSMP10HM3/85A is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature, making it fully suitable for under-hood and transmission-control module applications. Its DO-220AA package, halogen-free construction, and MSL Level 1 reflow compatibility meet stringent automotive manufacturing and reliability requirements.
What is the clamping voltage of TPSMP10HM3/85A at its rated peak pulse current?
The TPSMP10HM3/85A clamps to a maximum of 15.0 V at its rated peak pulse current of 20.0 A (10/1000 μs waveform). This clamping performance, combined with its 200 W peak pulse power rating, ensures downstream components see controlled overvoltage stress during standardized surge events.
Does TPSMP10HM3/85A have a unidirectional or bidirectional configuration?
The TPSMP10HM3/85A is a unidirectional TVS diode, meaning it conducts only during positive voltage transients relative to its cathode. Its polarity is marked by a color band on the cathode end, and it must be oriented with cathode toward the protected circuit's reference (e.g., ground or negative rail) to function correctly.
What packaging option does TPSMP10HM3/85A use for volume shipment?
The TPSMP10HM3/85A ships in 13-inch diameter plastic tape and reel format, with a base quantity of 10,000 units per reel. This packaging supports high-speed automated pick-and-place assembly and complies with industry-standard EIA-481 specifications for SMT handling.
