Product details
Overview
TPSMP11AHE3/85A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, with 10.5 V to 11.6 V breakdown voltage (VBR), 19.2 A peak pulse current (IPPM), and 15.6 V clamping voltage (VC) at IPPM, designed for ESD and surge protection of signal lines in automotive sensor units and power electronics.
For engineers reviewing the TPSMP11AHE3/85A datasheet, TPSMP11AHE3/85A pinout, TPSMP11AHE3/85A application, or TPSMP11AHE3/85A equivalent, key selection criteria include its AEC-Q101 qualification, 1.0 mm profile, 15.6 V clamping under 10/1000 µs surge, RoHS-compliant matte tin terminals, and DO-220AA mechanical compatibility with automated SMT placement.
Technical Context
This TVS diode operates as a unidirectional clamping device, activated above its 10.5–11.6 V breakdown threshold to divert transients away from sensitive downstream circuitry. Its patented PAR oxide-passivated chip construction ensures stable VBR tolerance and low incremental surge resistance.
It delivers 300 W peak pulse power (10/1000 µs waveform) at 25 °C, derates linearly above TA = 25 °C per Fig. 2, and maintains operation across -65 °C to +185 °C junction temperature range-critical for under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 10.5 V / 11.6 V - defines precise clamping activation window for overvoltage events |
| VC @ IPPM | 15.6 V - maximum voltage seen by protected IC during 19.2 A transient, limiting stress on downstream components |
| IPPM | 19.2 A - peak surge current it safely clamps without failure under standard 10/1000 µs waveform |
| PPPM | 300 W - transient energy-handling capability at 25 °C, sufficient for ISO 7637-2 Pulse 1/2a/2b/5a |
| VWM | 1.0 V - maximum working voltage before leakage exceeds 2.0 µA, enabling use on low-voltage logic/sensor lines |
| TJ max | +185 °C - enables reliable operation in high-temperature engine bay locations |
| Package | DO-220AA (SMP) - 1.0 mm height, 2.54 mm lead pitch, MSL Level 1, compatible with reflow up to 260 °C |
Pinout & Package
DO-220AA (SMP) surface-mount package: ultra-low-profile (1.0 mm typical height), cathode indicated by color band, matte tin-plated leads compliant with J-STD-002 and JESD22-B102, qualified to JESD201 Class 2 whisker test.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to protected line (e.g., CAN_H, LIN, sensor output); conducts only during reverse transient clamp |
| Cathode | Current exit point during reverse-biased clamping | Connected to ground plane; carries full surge current during transient suppression event |
Key Features
| Feature | Design Value |
|---|---|
| Patented PAR oxide passivation | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure |
| AEC-Q101 qualification | Validated for automotive applications including engine control, ADAS sensors, and body electronics |
| MSL Level 1 rating | Enables single-reflow assembly without moisture sensitivity concerns, reducing manufacturing risk |
| Low 1.0 mm profile | Minimizes board space and enables placement near connectors or ICs requiring localized protection |
| RoHS/WEEE compliance | Meets global environmental regulations for automotive and industrial end equipment |
Applications
| Automotive Sensor Protection | CAN Bus Line Protection |
|---|---|
Use Scenario: Protecting analog output lines of pressure, temperature, or position sensors in engine control modules exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed between sensor output and microcontroller ADC input. Use Value: Limits voltage excursion to ≤15.6 V during 10/1000 µs surges, preventing ADC saturation and latch-up while maintaining signal integrity below 1.0 V stand-off. | Use Scenario: Safeguarding CAN_H and CAN_L differential pair against ESD (±8 kV contact) and ISO 7637-2 Pulse 1/2a in vehicle infotainment and gateway ECUs. IC Role / Device Role / Timing Role: Bidirectional protection implemented using two TPSMP11AHE3/85A devices (one per line) referenced to chassis ground. Use Value: Clamps transients within 1 ns response time while adding <1 pF junction capacitance, preserving CAN signal rise/fall times and bit-rate integrity up to 1 Mbps. |
| Industrial PLC I/O Protection | Consumer Appliance Motor Driver Protection |
Use Scenario: Shielding 24 V DC digital input channels in programmable logic controllers from field-wiring induced surges and ground bounce. IC Role / Device Role / Timing Role: Standoff-rated TVS placed between terminal block and optocoupler input stage. Use Value: Withstands repetitive 300 W pulses and maintains <2.0 µA leakage at 1.0 V, ensuring no false triggering during normal 24 V operation while suppressing >1 kV transients. | Use Scenario: Suppressing inductive kickback from brushed DC motors in smart home appliances (e.g., washing machine drum drives). IC Role / Device Role / Timing Role: Reverse-biased TVS across motor terminals to clamp flyback voltage during MOSFET turn-off. Use Value: Handles 40 A non-repetitive surge (IFSM) and clamps to 15.6 V, protecting 20 V-rated gate drivers and reducing electromagnetic emissions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A-E3/5AT | Higher VC (18.2 V), lower IPPM (13.2 A), SMA package (2.3 mm height) | Lacks AEC-Q101 qualification; not rated for automotive under-hood use | Select when cost-sensitive industrial designs require basic 11 V clamping without automotive qualification or ultra-low profile. |
| TPSMA6.8A-S | Lower VBR (6.45–7.14 V), same DO-220AA package, 300 W rating | Designed for 5 V logic rail protection; unsuitable for 12 V automotive systems due to premature clamping | Choose only for 3.3–5 V interface protection where tighter VBR tolerance and lower clamping voltage are required. |
Compared with SMAJ11A-E3/5AT and TPSMA6.8A-S, TPSMP11AHE3/85A uniquely combines AEC-Q101 qualification, 1.0 mm profile, and precise 10.5–11.6 V VBR for robust 12 V automotive signal line protection-making it irreplaceable in safety-critical sensor and communication interfaces.

FAQ
What is the clamping voltage of TPSMP11AHE3/85A under a 10/1000 µs surge?
The TPSMP11AHE3/85A has a maximum clamping voltage (VC) of 15.6 V at its rated peak pulse current (IPPM) of 19.2 A under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected circuitry remains below critical voltage thresholds during surge events.
Is TPSMP11AHE3/85A qualified for automotive applications?
Yes, TPSMP11AHE3/85A is AEC-Q101 qualified and designated as high-reliability/automotive grade (suffix "A"). It meets stringent requirements for temperature cycling, humidity resistance, and surge endurance-making it suitable for engine control units, ADAS sensors, and body electronics.
What does the "HE3/85A" suffix mean in TPSMP11AHE3/85A?
The "HE3" suffix indicates RoHS-compliant, high-reliability construction with matte tin-plated leads passing JESD201 Class 2 whisker testing. The "/85A" denotes packaging in 13-inch plastic tape-and-reel format with 10,000 units per reel-optimized for high-volume SMT assembly.
What is the standoff voltage (VWM) of TPSMP11AHE3/85A?
The standoff voltage (VWM) of TPSMP11AHE3/85A is 1.0 V, meaning it remains effectively non-conductive below this voltage with leakage current limited to ≤2.0 µA at 25 °C. This allows safe use on low-voltage signal paths without loading or interference.
Does TPSMP11AHE3/85A have polarity marking, and how is it identified?
Yes, TPSMP11AHE3/85A uses a color band to denote the cathode terminal, consistent with DO-220AA (SMP) package conventions. The banded end must be connected to ground or the reference node to enable proper unidirectional clamping behavior during transient events.
