Product details
Overview
TPSMP7.5HM3/85A 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 6.75 V to 8.25 V breakdown voltage (VBR), 300 W peak pulse power (10/1000 μs), and clamps to ≤25.6 V at 500 A peak surge current - ideal for protecting automotive sensor signal lines and microcontroller I/O pins.
For engineers reviewing the TPSMP7.5HM3/85A datasheet, TPSMP7.5HM3/85A pinout, TPSMP7.5HM3/85A application, or TPSMP7.5HM3/85A equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction temperature rating, low-profile 1.0 mm height, MSL Level 1 reflow compatibility, and uni-directional clamping behavior in compact surface-mount form.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional architecture enables integration into DC-biased signal paths where reverse conduction must be blocked while maintaining robust clamping during positive transients.
Rated for operation from –65 °C to +185 °C and qualified per AEC-Q101, the TPSMP7.5HM3/85A supports automotive-grade reliability requirements. The device meets J-STD-020 MSL Level 1 with 260 °C peak reflow profile and exhibits <150 μA maximum reverse leakage at 6.05 V stand-off voltage (VWM) and 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.75 V / 8.25 V - ensures reliable triggering above system operating voltage while avoiding false trips |
| VWM | 6.05 V - maximum continuous reverse voltage before significant leakage begins |
| IPPM | 500 A - peak surge current capability under 10/1000 μs waveform with derating above 25 °C |
| VC @ IPPM | ≤25.6 V - clamping voltage limiting stress on downstream ICs during ESD or load-dump events |
| PPPM | 300 W - peak pulse power handling capacity for transient suppression in automotive and industrial environments |
| TJ max | +185 °C - enables use in under-hood automotive modules and high-temperature industrial enclosures |
| Package | DO-220AA (SMP) - ultra-low-profile 1.0 mm height, compatible with automated SMT placement and space-constrained PCBs |
Pinout & Package
DO-220AA (SMP) package: cathode-indicating band on one end; two-terminal axial configuration with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Meets UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path | Connected to lower-potential side of protected line; conducts during positive transients when VAK exceeds VBR |
| Cathode | Clamping reference node | Marked by color band; tied to higher-potential rail (e.g., VCC or signal return); defines clamping threshold relative to this node |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces |
| 185 °C junction rating | Supports operation in high-temperature zones without thermal derating penalties up to rated power |
| 1.0 mm typical height | Enables placement beneath connectors or in stacked-board assemblies with strict Z-axis constraints |
| MSL Level 1 | Allows single-pass reflow at 260 °C peak without preconditioning, reducing manufacturing complexity |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a/5a) |
Applications
| Automotive Sensor Protection | Microcontroller I/O Clamping |
|---|---|
Use Scenario: Protecting LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) in engine compartments exposed to load dump and ISO 16750-2 transients. IC Role / Device Role: Uni-directional TVS placed between signal line and ground to clamp positive surges while blocking reverse leakage.

IC Role / Device Role: Low-capacitance clamping diode mounted directly at MCU pin to minimize trace inductance and ensure sub-nanosecond response. Use Value: Limits pin voltage to ≤25.6 V during 500 A surge, preserving MCU functionality without requiring external series impedance. |
| Industrial Motor Drive Control | Consumer Power Adapter Input Stage |
Use Scenario: Shielding gate drivers and feedback optocouplers in BLDC motor inverters from switching-induced voltage spikes and inductive kickback. IC Role / Device Role: Transient suppressor across isolated power rails (e.g., 12 V auxiliary supply) to absorb energy from relay coil de-energization. Use Value: Withstands repetitive 300 W pulses without degradation, ensuring long-term reliability in factory automation equipment. | Use Scenario: Input-stage surge protection for USB-C PD adapters and smart home AC/DC converters subjected to lightning-induced surges per IEC 61000-4-5. IC Role / Device Role: Primary clamping device across bulk capacitor terminals to limit voltage rise during 2 kV ring wave tests. Use Value: Delivers 300 W peak power dissipation in minimal footprint, eliminating need for larger DO-214AC packages and saving PCB area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A-E3/5AT | DO-214AC package (higher profile: 2.3 mm), 400 W PPPM, VC = 12.9 V @ 32.4 A | Higher clamping ratio but lower surge current; better suited for lower-energy ESD vs. automotive load dump | Select when board height allows larger package and clamping voltage margin is prioritized over surge current capacity |
| TPSMA6.8A-S | Same DO-220AA package, lower VBR (6.45–7.14 V), 300 W PPPM, VC = 10.5 V @ 500 A | Narrower breakdown tolerance (±5 %), tighter VWM/VBR margin - preferred for 5 V logic rail protection | Choose for 5 V systems requiring tighter voltage coordination between VWM and VCC, with identical mounting and thermal performance |
Compared with SMAJ7.5A-E3/5AT and TPSMA6.8A-S, the TPSMP7.5HM3/85A offers superior surge current handling (500 A) in the lowest possible profile (1.0 mm), making it optimal for space-constrained automotive modules where both mechanical fit and transient robustness are critical.

FAQ
What is the breakdown voltage range of the TPSMP7.5HM3/85A?
The TPSMP7.5HM3/85A has a specified breakdown voltage (VBR) range of 6.75 V to 8.25 V at 10 mA test current, measured per ANSI/IEEE C62.35. This range ensures consistent triggering above nominal 5 V or 6 V system rails while maintaining margin against false activation due to ripple or tolerance stack-up. The value is confirmed in the Vishay datasheet document 88471, Table on page 2.
Is the TPSMP7.5HM3/85A suitable for automotive applications?
Yes, the TPSMP7.5HM3/85A is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and cabin-mounted automotive electronics. Its DO-220AA package meets MSL Level 1 reflow requirements, and its 300 W peak pulse power supports ISO 7637-2 and ISO 16750-2 transient immunity testing. These attributes are explicitly stated in the Vishay TPSMP6.8–TPSMP43A datasheet revision 22-Jul-16.
What is the clamping voltage of the TPSMP7.5HM3/85A at its rated peak pulse current?
The TPSMP7.5HM3/85A clamps to a maximum of 25.6 V at its rated peak pulse current (IPPM) of 500 A under a 10/1000 μs waveform. This clamping voltage is measured with the device mounted on a PCB using 5.0 mm × 5.0 mm copper pads per terminal, as defined in the "Maximum Ratings" section of the Vishay datasheet 88471. It directly limits stress on downstream 5 V or 3.3 V ICs during surge events.
Does the TPSMP7.5HM3/85A have polarity marking, and how is it identified?
Yes, the TPSMP7.5HM3/85A features a cathode band - a visible color marking on the package body - that identifies the cathode terminal. Per the mechanical data in the Vishay datasheet, polarity is denoted by this band, and the anode is the opposite end. This marking is essential for correct orientation during PCB layout and automated placement, especially in uni-directional configurations where reverse bias must be maintained.
What packaging option does the TPSMP7.5HM3/85A use, and what is its reel quantity?
The TPSMP7.5HM3/85A is supplied in 13-inch diameter plastic tape and reel format with a base quantity of 10,000 pieces, indicated by the "/85A" suffix in the part number. This packaging supports high-volume SMT assembly and is documented in the "Ordering Information" section of the Vishay datasheet 88471. The HM3 suffix confirms halogen-free, RoHS-compliant, and AEC-Q101-qualified construction.
