Product details
Overview
TPSMP10AHE3/85A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) in DO-220AA (SMP) package, with 9.5 V to 10.5 V breakdown voltage (VBR), 14.5 V clamping voltage (VC) at 20.7 A peak pulse current, and 400 W peak pulse power rating for VBR ≥ 13 V - applied here per TPSMP10A family classification. It protects signal lines in automotive sensor units and ECUs against ESD and load dump transients.
For engineers reviewing the TPSMP10AHE3/85A datasheet, TPSMP10AHE3/85A pinout, TPSMP10AHE3/85A application, or TPSMP10AHE3/85A equivalent, key selection criteria include clamping performance under 10/1000 µs surge, AEC-Q101 qualification status, RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on FR-4 PCBs with 5.0 × 5.0 mm copper pads.
Technical Context
The TPSMP10AHE3/85A uses patented PAR oxide-passivated chip construction to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of fast-rising transients such as ISO 7637-2 pulse 1 and pulse 2b. Its unidirectional configuration provides forward conduction path during overvoltage events while maintaining low leakage (<5 µA at 8.55 V stand-off).
Thermal design is supported by a maximum junction temperature of +185 °C and steady-state power dissipation of 2.5 W at 75 °C ambient on infinite heatsink. The device meets MSL Level 1 per J-STD-020 and passes JESD201 Class 2 whisker testing due to its HE3 suffix construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.50 V / 10.5 V - ensures reliable triggering above system operating voltage (e.g., 8.55 V VWM) without false clamping |
| VC @ IPPM | 14.5 V at 20.7 A - limits downstream IC voltage stress during 10/1000 µs surge, critical for 12 V automotive rail protection |
| PPPM | 400 W - rated for VBR ≥ 13 V devices; TPSMP10A falls into this group per Vishay's PPPM tiering in Doc #88471 |
| IR @ VWM | <5.0 µA at 8.55 V - minimizes standby power loss and avoids interference in high-impedance sensor interfaces |
| TJ max | +185 °C - supports operation in under-hood environments and enables robust thermal margin in sealed enclosures |
| Package | DO-220AA (SMP) - 1.0 mm typical height, compatible with fine-pitch automated placement and reflow profiles up to 260 °C peak |
| AEC-Q101 | Qualified - certified for automotive electronics per stress test requirements including HTRB, HTGB, and temperature cycling |
Pinout & Package
DO-220AA (SMP) surface-mount package with cathode indicated by color band; terminals are matte tin-plated for solderability per J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input reference node for unidirectional clamping | Connected to protected line; conducts during reverse overvoltage to shunt energy to ground |
| Cathode | Clamp output / surge return path | Connected to system ground; defines polarity and enables low-VF (2.5 V @ 25 A) forward conduction |
Key Features
| Feature | Design Value |
|---|---|
| Patented PAR oxide passivation | Enables stable VBR tolerance and long-term reliability under repeated surge stress without parameter drift |
| MSL Level 1 rating | Allows unlimited floor life and compatibility with standard lead-free reflow profiles up to 260 °C peak |
| Low profile (1.0 mm typical height) | Reduces board space and mechanical interference in tight automotive modules like ADAS camera housings |
| JESD201 Class 2 whisker resistance | Eliminates risk of tin whisker growth-induced short circuits in high-reliability automotive control units |
| RoHS/WEEE compliant | Meets EU regulatory requirements for hazardous substances and end-of-life handling in global vehicle supply chains |

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-E3/5AT | DO-214AC (SMA) package; 10 V VBR min/max = 10.0–11.1 V; 200 W PPPM; higher VC = 16.0 V @ 12.3 A | Limited to lower-energy transients; not AEC-Q101 qualified; suitable for industrial/commercial but not automotive grade | Select when cost sensitivity outweighs automotive qualification and higher clamping voltage is acceptable |
| TPSMA6.8A-S | DO-214AC (SMA); 6.8 V VBR; 400 W PPPM; VC = 11.2 V @ 35.7 A; AEC-Q101 qualified | Lower VBR better suited for 5 V logic rails; incompatible with 12 V systems requiring ≥9.5 V standoff | Choose only for sub-9 V nominal supply protection; not interchangeable with TPSMP10AHE3/85A due to voltage mismatch |
Compared with SMAJ10A-E3/5AT and TPSMA6.8A-S, the TPSMP10AHE3/85A delivers automotive-grade reliability in a lower-profile DO-220AA package, tighter VBR tolerance, and optimized clamping for 12 V systems - making it the preferred choice where AEC-Q101 compliance and space-constrained layouts are mandatory.
