Product details
Overview
TPSMP7.5AHM3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the PAR® family, designed for high-reliability automotive and industrial overvoltage protection. It features a 7.13 V to 7.88 V breakdown voltage (VBR), 6.40 V stand-off voltage (VWM), 300 W peak pulse power (10/1000 µs), 26.5 V clamping voltage at 19.2 A peak pulse current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPSMP7.5AHM3_A/I datasheet, TPSMP7.5AHM3_A/I pinout, TPSMP7.5AHM3_A/I application, or TPSMP7.5AHM3_A/I equivalent, key selection criteria include its AEC-Q101 qualification, SMP (DO-220AA) package with 1.0 mm profile, unidirectional polarity, low incremental surge resistance, and suitability for signal-line and IC-level ESD/surge protection in space-constrained automotive ECUs.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve fast response time (<1 ns), low clamping ratio (VC/VBR ≈ 3.5), and stable performance across -65 °C to +185 °C. Its junction passivation enables robust reliability under repetitive surge stress and high-temperature operation.
The device is optimized for 10/1000 µs waveform compliance per IEC 61000-4-5 and ANSI/IEEE C62.35, with derated surge capability above 25 °C ambient and MSL Level 1 moisture sensitivity rating (peak reflow 260 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V - defines precise voltage threshold at which clamping initiates under 10 mA test current |
| VWM | 6.40 V - maximum continuous reverse operating voltage before leakage exceeds 150 μA |
| IPPM | 19.2 A - peak surge current it safely clamps during 10/1000 µs transients on FR-4 PCB |
| VC @ IPPM | 26.5 V - clamped voltage seen by protected circuit during full-rated surge event |
| PPPM | 300 W - peak pulse power handling capacity, enabling robust protection against ISO 7637-2 Pulse 1/2a/5a |
| TJ max | +185 °C - supports under-hood automotive placement without thermal derating penalties |
| Package | SMP (DO-220AA) - ultra-low-profile surface-mount package (1.0 mm height) compatible with automated SMT assembly |
Pinout & Package
TPSMP7.5AHM3_A/I is a two-terminal unidirectional TVS diode in the SMP (DO-220AA) package. Polarity is marked by a cathode band on the body; the cathode terminal connects to the protected line's return path or ground reference, while the anode connects to the line being protected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Protected signal line input | Connected directly to the vulnerable node (e.g., CAN_H, LIN, sensor output); conducts surge current toward cathode during overvoltage |
| Cathode | Clamp reference / ground return | Connected to local system ground or low-impedance return path; establishes clamping reference and completes surge current loop |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance per JESD47 |
| Junction passivation | Reduces surface leakage and enhances long-term stability under humid/harsh environments |
| MSL Level 1 | Enables standard SMT reflow without pre-baking; peak solder temperature up to 260 °C supported |
| Low profile (1.0 mm height) | Minimizes board space and mechanical interference in stacked or shielded modules |
| Halogen-free & RoHS-compliant | Meets global environmental compliance requirements for automotive and industrial OEM supply chains |
Applications
| Automotive Sensor Interface Protection | CAN Bus Line Protection |
|---|---|
Use Scenario: Protecting analog outputs of pressure, temperature, or position sensors in engine control units exposed to load dump and ISO 7637-2 transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output and microcontroller ADC input to clamp surges before they reach sensitive analog front-end. Use Value: Maintains signal integrity below 26.5 V clamping level while surviving repeated 19.2 A pulses-critical for ASIL-B functional safety paths. | Use Scenario: Safeguarding CAN_H and CAN_L lines in body control modules against ESD (IEC 61000-4-2) and coupled transients. IC Role / Device Role / Timing Role: Two-device configuration (one per line) referenced to chassis ground, providing bidirectional protection via unidirectional devices in opposing orientation. Use Value: 300 W peak power rating ensures immunity to ISO 16750-2 jump-start and battery reversal events without degradation. |
| Industrial PLC Digital Input Protection | Consumer Appliance Motor Driver Protection |
Use Scenario: Shielding 24 V DC digital inputs in programmable logic controllers from field-wiring induced surges and inductive kickback. IC Role / Device Role / Timing Role: Placed upstream of optocoupler or Schmitt trigger input stage to limit voltage excursion during 10/1000 µs transients. Use Value: 6.40 V VWM allows reliable operation across full 24 V ±10 % range while rejecting >7.13 V faults-reducing false triggering. | Use Scenario: Protecting gate drivers and MCU I/O pins in smart appliance motor control boards from back-EMF spikes during BLDC commutation. IC Role / Device Role / Timing Role: Mounted at motor driver IC supply pins and signal feedback paths to absorb energy from inductive switching noise. Use Value: +185 °C TJ rating enables placement near heat-generating MOSFETs without thermal shutdown or parameter drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | Higher VC (30.0 V), lower PPPM (400 W only at VBR ≥13 V; 200 W at 7.5 V), SMA package (2.3 mm height) | Less suitable for space-constrained automotive modules; higher clamping may risk downstream ICs | Select TPSMP7.5AHM3_A/I when board height <1.1 mm and clamping voltage ≤26.5 V is required |
| 1.5SMC7.5A | Same VBR range but larger SMC package (2.7 mm height), 400 W PPPM at 7.5 V, no AEC-Q101 qualification | Not approved for automotive use; requires larger PCB footprint and thermal relief pads | Choose TPSMP7.5AHM3_A/I for AEC-Q101 compliance, low-profile layout, and production-grade automotive sourcing |
Compared with SMAJ7.5A and 1.5SMC7.5A, TPSMP7.5AHM3_A/I delivers superior height efficiency (1.0 mm vs. ≥2.3 mm), tighter clamping (26.5 V vs. ≥30.0 V), and certified automotive qualification-making it optimal for next-generation compact ECU designs where thermal margin and reliability are non-negotiable.

FAQ
What is the exact breakdown voltage range for TPSMP7.5AHM3_A/I?
The TPSMP7.5AHM3_A/I has a guaranteed breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current, measured per ANSI/IEEE C62.35. This tight tolerance ensures consistent clamping initiation across production lots and supports precise overvoltage threshold design in automotive and industrial circuits.
Is TPSMP7.5AHM3_A/I suitable for bidirectional transient protection?
No, TPSMP7.5AHM3_A/I is a unidirectional TVS diode and must be used with correct polarity-cathode to ground or reference rail. For true bidirectional protection, two TPSMP7.5AHM3_A/I devices can be connected in series opposition, or a dedicated bidirectional part like TPSMD7.5AHM3 should be selected instead.
Does TPSMP7.5AHM3_A/I meet AEC-Q101 requirements?
Yes, TPSMP7.5AHM3_A/I is fully AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and surge endurance. The HM3 suffix explicitly denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction per Vishay documentation.
What is the maximum clamping voltage of TPSMP7.5AHM3_A/I under rated surge conditions?
The maximum clamping voltage (VC) of TPSMP7.5AHM3_A/I is 26.5 V at 19.2 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured on a standard FR-4 PCB with 5.0 mm × 5.0 mm copper pads per terminal, ensuring realistic system-level protection performance.
Can TPSMP7.5AHM3_A/I be used in place of SMAJ7.5A without layout changes?
No-TPSMP7.5AHM3_A/I uses the SMP (DO-220AA) package (2.20 mm × 3.61 mm), while SMAJ7.5A uses SMA (DO-214AC) (4.32 mm × 2.62 mm). Footprint and pad layout differ significantly; direct replacement requires PCB redesign to accommodate the smaller, lower-profile SMP outline and revised thermal pad dimensions.
