Product details
Overview
TPSMP7.5AHM3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the SMP (DO-220AA) package, designed for high-reliability automotive and industrial surge protection. It features a 7.13 V minimum breakdown voltage (VBR), 6.40 V stand-off voltage (VWM), 300 W peak pulse power (10/1000 µs), 26.5 V clamping voltage at 11.3 A peak pulse current, and AEC-Q101 qualification for under-hood electronics.
For engineers reviewing the TPSMP7.5AHM3_A/H datasheet, TPSMP7.5AHM3_A/H pinout, TPSMP7.5AHM3_A/H application, or TPSMP7.5AHM3_A/H equivalent, this page delivers verified electrical parameters, mechanical dimensions, junction temperature limits, clamping behavior, and automotive-grade reliability data required for ESD/surge co-design in sensor interfaces, power rails, and signal lines.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD (IEC 61000-4-2) and lightning-induced transients (IEC 61000-4-5). Its 185 °C maximum junction temperature and MSL Level 1 rating support reflow soldering at 260 °C peak and long-term operation in engine control units and ADAS modules.
The device operates exclusively in unidirectional mode with cathode-band polarity marking, requires no bias circuitry, and delivers stable clamping performance across -65 °C to +185 °C ambient range. Its 1.0 mm typical height and DO-220AA footprint enable dense PCB layouts while maintaining 2.5 W steady-state power dissipation on infinite heatsink at 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V at 10 mA - defines precise voltage threshold where avalanche conduction begins, critical for matching system overvoltage tolerance |
| VWM | 6.40 V - maximum continuous reverse voltage before leakage exceeds 150 μA, sets safe operating margin below VBR |
| VC @ IPPM | 26.5 V at 11.3 A - clamped voltage during 10/1000 µs surge, determines protected IC's maximum stress level |
| PPPM | 300 W - peak pulse power handling capability, directly supports 12 V automotive load-dump and ISO 7637-2 pulse 5a/b immunity |
| TJ max | +185 °C - enables placement near heat sources (e.g., power MOSFETs, DC/DC converters) without derating |
| AEC-Q101 | Qualified - confirms reliability validation per automotive stress test standards including HTGB, HTRB, and temperature cycling |
| Package | SMP (DO-220AA) - 2.18 mm × 3.61 mm × 1.0 mm footprint with matte tin-plated leads, compatible with J-STD-002 solderability and JESD201 Class 2 whisker resistance |
Pinout & Package
TPSMP7.5AHM3_A/H is a two-terminal surface-mount TVS diode in the SMP (DO-220AA) package. The cathode is marked by a color band on the body; the anode is the unmarked end. Leads are matte tin-plated and compliant with J-STD-002 and JESD 22-B102 solderability requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction; connected to lower-potential side of protected line | Enables unidirectional clamping only when reverse-biased - must be placed between protected node and ground or lower rail |
| Cathode | Current exit terminal during avalanche conduction; marked by color band | Connected to higher-potential side (e.g., 12 V supply rail or signal line) - defines directionality and ensures correct orientation during automated placement |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation optimized design | Reduces leakage drift and improves long-term stability under thermal cycling and humidity exposure |
| Very low profile (1.0 mm typical height) | Enables integration into space-constrained modules such as radar sensors and camera ECUs without interfering with shield cans or connectors |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, improving protection margin for 3.3 V and 5 V logic interfaces |
| Meets MSL Level 1, peak reflow 260 °C | Supports single-pass lead-free reflow without moisture-related popcorn failure or delamination |
| Halogen-free, RoHS-compliant, AEC-Q101 qualified | Meets automotive supply chain compliance requirements for material content, environmental safety, and reliability validation |

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 | Same VBR range (7.13–7.88 V), but SMA (DO-214AC) package (4.5 mm × 2.7 mm × 2.2 mm); 200 W PPPM, higher profile, lower thermal mass | Limited to non-automotive or less space-constrained designs due to larger footprint and absence of AEC-Q101 qualification | Select SMAJ7.5A only if board area allows larger package and automotive qualification is not required |
| TPSMA6.8A | Lower VBR (6.45–7.14 V), same SMP package, 250 W PPPM, 23.8 V clamping at 10.5 A; identical AEC-Q101 and MSL Level 1 ratings | Better suited for 5 V rail protection where tighter VWM/VBR margin is needed, but insufficient for 12 V systems requiring ≥6.4 V standoff | Choose TPSMA6.8A for 5 V logic lines; TPSMP7.5AHM3_A/H remains optimal for 12 V automotive supply rail protection |
Compared with SMAJ7.5A and TPSMA6.8A, TPSMP7.5AHM3_A/H uniquely combines 300 W surge capacity, AEC-Q101 qualification, and ultra-low 1.0 mm height in the SMP package - making it the only option meeting all three criteria for next-generation compact automotive ECUs.

FAQ
What is the clamping voltage of the TPSMP7.5AHM3_A/H at its rated peak pulse current?
The TPSMP7.5AHM3_A/H has a maximum clamping voltage (VC) of 26.5 V at 11.3 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during surge events. The TPSMP7.5AHM3_A/H maintains this clamping performance across its full operating temperature range.
Is the TPSMP7.5AHM3_A/H suitable for automotive applications?
Yes, the TPSMP7.5AHM3_A/H is AEC-Q101 qualified and rated for operation from -65 °C to +185 °C junction temperature, making it suitable for under-hood and ADAS applications. Its halogen-free, RoHS-compliant construction and MSL Level 1 reflow compatibility further align with automotive manufacturing requirements. The TPSMP7.5AHM3_A/H is explicitly listed in Vishay's automotive-grade product portfolio.
What package type does the TPSMP7.5AHM3_A/H use, and what are its key mechanical dimensions?
The TPSMP7.5AHM3_A/H uses the SMP (DO-220AA) package: 2.18 mm length × 3.61 mm width × 1.0 mm typical height, with cathode marked by a color band. Lead finish is matte tin, compliant with J-STD-002 and JESD 22-B102. The TPSMP7.5AHM3_A/H's compact size supports high-density placement in modern automotive ECUs and camera modules.
How does the TPSMP7.5AHM3_A/H compare to the TPSMP6.8AHM3_A/H in terms of voltage ratings?
The TPSMP7.5AHM3_A/H has a higher breakdown voltage range (7.13–7.88 V) and stand-off voltage (6.40 V) than the TPSMP6.8AHM3_A/H (6.45–7.14 V VBR, 5.80 V VWM). Both share identical package, surge rating (300 W vs. 250 W), and AEC-Q101 qualification. The TPSMP7.5AHM3_A/H is selected when system-level overvoltage thresholds require tighter margin above 6.4 V nominal rails.
Does the TPSMP7.5AHM3_A/H have bidirectional capability?
No, the TPSMP7.5AHM3_A/H is strictly unidirectional. Its cathode-band marking indicates polarity-sensitive placement: cathode connects to the protected line, anode to ground. Bidirectional variants (e.g., TPSMP7.5CA) are separate part numbers. Using the TPSMP7.5AHM3_A/H in reverse orientation will result in forward conduction and failure to suppress positive transients.
