Product details
Overview
MSMP7.5AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the MicroSMP (DO-219AD) package, with 7.5 V stand-off voltage (VWM), 8.33–9.21 V breakdown voltage (VBR), 150 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive electronics protection against inductive switching transients and ESD events.
For engineers reviewing the MSMP7.5AHM3/H datasheet, MSMP7.5AHM3/H pinout, MSMP7.5AHM3/H application, or MSMP7.5AHM3/H equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance at 11.6 A IPPM, junction-to-mount thermal resistance (30 °C/W), and AEC-Q101 qualification status - all critical for automotive sensor line and MOSFET gate protection design.
Technical Context
This TVS diode uses an oxide planar chip junction and operates exclusively in unidirectional mode, with cathode denoted by a color band. Its low-profile construction (0.65 mm typical height) enables high-density PCB layouts while maintaining robust surge handling per IEC 61000-4-2 (15 kV air, 8 kV contact).
Clamping voltage is defined by VCL = RD × IPP + VBR(max); for MSMP7.5AHM3/H, RD is 0.317 Ω, yielding 12.9 V max clamping at 11.6 A (10/1000 μs). Thermal performance is specified for mounting on 6.0 mm × 6.0 mm copper pads, delivering RθJM = 30 °C/W and enabling reliable operation up to TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.5 V - maximum reverse stand-off voltage before conduction begins; sets operating margin above circuit nominal voltage |
| VBR (min/max) | 8.33 V / 9.21 V at 1.0 mA - defines precise breakdown threshold for predictable turn-on during overvoltage |
| PPPM (10/1000 μs) | 150 W - peak transient energy absorption capability under standard lightning-surge waveform |
| VC @ IPPM | 12.9 V at 11.6 A - maximum clamped voltage seen by protected IC/MOSFET during rated surge event |
| RD | 0.317 Ω - dynamic resistance determining clamping slope; lower value improves voltage limiting fidelity |
| TJ max | 150 °C - maximum junction temperature defining thermal design limits and lifetime reliability envelope |
| ESD rating | 15 kV (air), 8 kV (contact) - meets IEC 61000-4-2 Level 4 for system-level ESD immunity validation |
Pinout & Package
Package: MicroSMP (DO-219AD), ultra-low-profile surface-mount case with matte tin-plated terminals, halogen-free, RoHS-compliant, and AEC-Q101 qualified. Dimensions: 2.70 mm × 1.40 mm × 0.65 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction; connected to ground or low-side reference | Provides return path for surge current; must be routed to low-impedance ground plane for effective clamping |
| Cathode | Current exit terminal during reverse-biased clamping; marked by color band | Connected to protected signal/power line; polarity must match circuit voltage polarity to avoid damage |
Key Features
| Feature | Design Value |
|---|---|

| MicroSMP footprint | Enables automated placement and supports >10,000 units/hour SMT throughput without tombstoning risk |
| MSL Level 1 | Unlimited floor life at ≤30 °C/60% RH; no bake required prior to reflow (peak 260 °C) |
| Oxide planar junction | Delivers tight VBR tolerance (±5.5%) and stable leakage (<50 μA at VWM) across temperature and lifetime |
| Low clamping ratio | VCL/VWM = 1.72 - ensures minimal overvoltage stress on downstream components during transient events |
Applications
| Automotive Sensor Protection | Industrial Motor Drive Inputs |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load-dump and inductive kickback in 12 V vehicle subsystems. IC Role / Device Role: Unidirectional TVS placed between signal line and chassis ground to clamp transients before reaching sensitive input stages. Use Value: Limits voltage excursion to ≤12.9 V during 11.6 A surges, preserving signal integrity and preventing latch-up in automotive-grade microcontrollers. | Use Scenario: Safeguarding PLC analog input modules and encoder interfaces against back-EMF from solenoids, relays, and brushed DC motors. IC Role / Device Role: Standoff-clamp TVS on 0–10 V or 4–20 mA signal lines to absorb repetitive switching transients without degradation.

IC Role / Device Role: Low-capacitance unidirectional suppressor placed inline with signal traces to divert ESD current away from PHY IC. Use Value: Junction capacitance <15 pF at 0 V bias ensures <0.1 dB insertion loss at 480 MHz, preserving USB signal integrity. |
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-Q | Higher VBR (8.33–9.21 V same), but SMA package (larger footprint, 2.5 mm × 4.5 mm) and higher RθJA (50 °C/W vs. 30 °C/W) | Less suitable for space-constrained automotive modules; requires larger pad layout and exhibits slower thermal recovery | Select when legacy SMA footprint compatibility is required and board area permits |
| SMCJ7.5A-H | Same MicroSMP package, but 1500 W PPPM rating and higher VC (13.3 V at 113 A); not AEC-Q101 qualified | Over-specified for low-energy ESD; lacks automotive qualification and may introduce unnecessary cost and layout complexity | Choose only for non-automotive high-energy surge environments where AEC-Q101 is not mandated |
Compared with SMAJ7.5A-Q and SMCJ7.5A-H, MSMP7.5AHM3/H delivers optimal balance of automotive qualification, ultra-compact size, and precise 7.5 V standoff-making it the preferred choice for next-generation ADAS sensor nodes and compact motor control PCBs where thermal management and space are critical.

FAQ
What is the exact breakdown voltage range for MSMP7.5AHM3/H?
The MSMP7.5AHM3/H has a guaranteed breakdown voltage (VBR) range of 8.33 V to 9.21 V measured at 1.0 mA test current, per Vishay Document Number 89457. This tight tolerance ensures predictable turn-on behavior during overvoltage events and supports accurate system-level margin analysis. The VBR specification applies directly to the MSMP7.5AHM3/H variant and is validated across the full operating temperature range.
Is MSMP7.5AHM3/H suitable for bidirectional transient protection?
No, MSMP7.5AHM3/H is unidirectional only, as explicitly stated in the Vishay datasheet. It conducts only during reverse-biased overvoltage events and must be oriented with the cathode band toward the protected line. For bidirectional protection, a separate device such as the SMBJ7.5CA or equivalent would be required - MSMP7.5AHM3/H does not support symmetrical clamping.
What is the maximum clamping voltage of MSMP7.5AHM3/H at its rated surge current?
The maximum clamping voltage (VC) of MSMP7.5AHM3/H is 12.9 V at 11.6 A peak pulse current (IPPM) under the 10/1000 μs waveform. This value is derived from the dynamic resistance (RD = 0.317 Ω) and maximum VBR (9.21 V), per the formula VCL = RD × IPP + VBR(max). This clamping level is confirmed in the Electrical Characteristics table for MSMP7.5A on page 2 of Document 89457.
Does MSMP7.5AHM3/H meet automotive qualification standards?
Yes, MSMP7.5AHM3/H is AEC-Q101 qualified, as indicated by the "HM3" suffix and confirmed in the Mechanical Data and Immunity sections of the Vishay datasheet. It passes stress tests including temperature cycling, high-temperature operating life, and ESD per AEC-Q101-001 (H3B class, >8 kV contact discharge), making it suitable for under-hood and cabin automotive applications.
What is the thermal resistance from junction to mount for MSMP7.5AHM3/H?
The junction-to-mount thermal resistance (RθJM) for MSMP7.5AHM3/H is 30 °C/W when mounted on 6.0 mm × 6.0 mm copper pads, per the Thermal Characteristics table in Document 89457. This value enables accurate thermal modeling for high-reliability designs and confirms suitability for continuous operation at elevated ambient temperatures when proper PCB copper area is implemented.
