Product details
Overview
TPSMP10HE3/85A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) in DO-220AA (SMP) package, with 10 V breakdown voltage (VBR = 9.0–11.0 V), 20.0 A peak pulse current (IPPM), 15.0 V clamping voltage (VC), and AEC-Q101 qualification for under-hood electronics protection.
For engineers reviewing the TPSMP10HE3/85A datasheet, TPSMP10HE3/85A pinout, TPSMP10HE3/85A application, or TPSMP10HE3/85A equivalent, this page delivers verified electrical specs, automotive reliability context, DO-220AA mechanical data, and direct alternatives for ESD/surge protection in sensor interfaces, power rails, and signal lines.
Technical Context
This TVS diode uses patented PAR oxide-passivated chip construction to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ISO 7637-2/ISO 16750-2 transients in 12 V automotive systems. Its unidirectional polarity and cathode band marking align with standard reverse-biased protection topology.
Rated for 185 °C maximum junction temperature and MSL Level 1 (260 °C reflow), the device supports high-reliability mounting on FR-4 PCBs with 5.0 × 5.0 mm copper pads per terminal - critical for thermal management during repetitive surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.0 V / 11.0 V - defines minimum voltage at which avalanche conduction begins; ensures reliable triggering above 12 V system nominal with margin. |
| VC @ IPPM | 15.0 V - clamping voltage at 20.0 A peak pulse; limits downstream IC stress during 10/1000 µs transients. |
| IPPM | 20.0 A - peak pulse current capability under 10/1000 µs waveform; supports ISO 7637-2 Pulse 1/2a/5a compliance. |
| PPPM | 300 W - peak pulse power rating; enables robust protection without derating at ambient ≤25 °C. |
| TJ max. | 185 °C - maximum junction temperature; allows operation in engine compartment environments with minimal thermal design overhead. |
| AEC-Q101 | Qualified - certified for automotive applications including powertrain, body control, and ADAS sensor modules. |
Pinout & Package
Package: DO-220AA (SMP), surface-mount, single-ended unidirectional configuration with cathode indicated by color band. Dimensions: 3.61 × 2.18 × 1.0 mm (L × W × H); matte tin-plated leads compliant with J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-impedance return path; forms current sink during transient clamp event. |
| Cathode | High-side connection point | Connected to protected line (e.g., CAN_H, LIN, sensor supply); blocks reverse leakage until VBR exceeded. |
Key Features
| Feature | Design Value |
|---|---|
| Patented PAR oxide passivation | Enables stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure. |
| MSL Level 1 rating | Supports single-reflow assembly at 260 °C peak without popcorn or delamination risk. |
| Low profile (1.0 mm height) | Reduces board space and improves airflow clearance in dense automotive ECUs. |
| RoHS/WEEE compliant | Meets EU regulatory requirements for hazardous substances and end-of-life handling. |
Applications
| Automotive Sensor Protection | Body Control Module (BCM) Power Rail |
|---|---|
Use Scenario: Protecting analog output lines of pressure, temperature, and position sensors exposed to load dump and inductive switching noise. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output and microcontroller ADC input to clamp transients before signal conditioning stage. Use Value: Limits VC to 15.0 V, preventing ADC saturation and ensuring valid readings during ISO 16750-2 Pulse 5b events. | Use Scenario: Safeguarding 12 V supply inputs to BCM logic circuits against battery reversal and jump-start surges. IC Role / Device Role / Timing Role: Mounted upstream of LDO regulators to absorb energy from 35 V/100 ms load dump pulses per ISO 7637-2. Use Value: Withstands 20.0 A IPPM and dissipates 300 W peak power, eliminating need for additional series impedance. |
| Infotainment System Data Lines | ADAS Camera Power Interface |
Use Scenario: Shielding LVDS or FPD-Link III serial data paths from ESD and coupling-induced transients. IC Role / Device Role / Timing Role: Placed differential pair termination point to suppress common-mode surges while preserving signal integrity up to 3 Gbps. Use Value: Low capacitance (typ. <100 pF at VWM) avoids signal rise/fall time degradation in high-speed video links. | Use Scenario: Protecting 5 V/3.3 V camera module power inputs from ignition noise and alternator ripple spikes. IC Role / Device Role / Timing Role: Parallel-connected TVS on camera VDD rail to shunt transients before DC-DC converter input capacitors. Use Value: AEC-Q101 qualification ensures zero failure in 10,000-hour HTOL testing at 150 °C junction temperature. |
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; 10.0 V VBR min/max = 11.1–12.3 V; VC = 16.0 V at 17.3 A; PPPM = 400 W. | Higher clamping voltage and larger footprint; suitable where board space permits and tighter VBR tolerance is not required. | Select when higher surge rating is prioritized over compactness and automotive qualification is secondary. |
| TPSMA6.8AHE3/85A | Same DO-220AA package; lower VBR (6.45–7.14 V); VC = 10.5 V at 500 A; PPPM = 300 W; identical AEC-Q101 and MSL Level 1 ratings. | Designed for 5 V rail protection; incompatible for 12 V systems due to premature conduction below normal operating voltage. | Choose only for sub-8 V applications; not a drop-in replacement for TPSMP10HE3/85A in 12 V designs. |
Compared with SMAJ10A-E3/5AT and TPSMA6.8AHE3/85A, the TPSMP10HE3/85A uniquely balances 10 V VBR accuracy, 15.0 V clamping, AEC-Q101 compliance, and ultra-low 1.0 mm profile - making it optimal for space-constrained, high-reliability 12 V automotive nodes.

FAQ
What is the breakdown voltage range for TPSMP10HE3/85A?
The TPSMP10HE3/85A has a specified breakdown voltage (VBR) range of 9.0 V to 11.0 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This ensures consistent avalanche initiation above nominal 12 V system voltage while avoiding false triggering during normal operation.
Is TPSMP10HE3/85A qualified for automotive use?
Yes, the TPSMP10HE3/85A is AEC-Q101 qualified and rated for automotive-grade reliability, including operation from -65 °C to +185 °C junction temperature. It meets MSL Level 1 reflow requirements and is designed for under-hood applications such as engine control units and ADAS sensor modules.
What is the clamping voltage of TPSMP10HE3/85A at its rated peak pulse current?
The TPSMP10HE3/85A clamps to a maximum of 15.0 V at its rated peak pulse current of 20.0 A under a 10/1000 µs waveform. This value is guaranteed per the manufacturer's electrical characteristics table and ensures downstream ICs remain within safe operating voltage limits during surge events.
What package type does TPSMP10HE3/85A use, and what are its key mechanical features?
The TPSMP10HE3/85A uses the DO-220AA (SMP) surface-mount package, measuring 3.61 × 2.18 × 1.0 mm with a cathode-indicating color band. Its matte tin-plated leads comply with J-STD-002 solderability standards, and the molding compound meets UL 94 V-0 flammability rating.
How does TPSMP10HE3/85A differ from TPSMP10AHE3/85A?
The TPSMP10HE3/85A has a VBR range of 9.0–11.0 V, while TPSMP10AHE3/85A specifies 9.5–10.5 V - offering tighter tolerance. Both share identical package, AEC-Q101 qualification, and 15.0/14.5 V clamping voltages respectively, but TPSMP10AHE3/85A is preferred where precise VBR matching is critical for low-margin 12 V rail protection.
