Product details
Overview
MSMP7.0AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the MicroSMP (DO-219AD) package, with 7.0 V stand-off voltage (VWM), 7.78–8.60 V breakdown voltage (VBR), and 150 W peak pulse power (10/1000 μs). It provides ESD protection up to 15 kV (air) and 8 kV (contact), and is AEC-Q101 qualified for automotive sensor line protection.
For engineers reviewing the MSMP7.0AHM3/H datasheet, MSMP7.0AHM3/H pinout, MSMP7.0AHM3/H application, or MSMP7.0AHM3/H equivalent, key selection criteria include clamping voltage (12.0 V max at 12.5 A), low-profile height (0.65 mm), halogen-free RoHS-compliant construction, and suitability for high-reliability automotive and industrial PCB layouts with tight space constraints.
Technical Context
This TVS diode uses an oxide planar chip junction and unidirectional polarity, optimized for fast transient suppression on signal lines where reverse leakage must remain ≤50 μA at 7.0 V. Its thermal resistance is 250 °C/W (junction-to-ambient) and 30 °C/W (junction-to-mount), enabling stable operation up to +150 °C junction temperature.
The device meets J-STD-020C MSL Level 1 with 260 °C reflow peak, supports automated placement, and features matte tin-plated terminals compliant with JESD 22-B102 and J-STD-002 solderability standards. Polarity is marked by a cathode band on the top surface.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 7.78 V / 8.60 V at 10 mA - ensures reliable turn-on within defined tolerance for predictable protection threshold |
| VCL max | 12.0 V at 12.5 A (10/1000 μs) - limits voltage seen by downstream ICs during surge events |
| PPPM | 150 W (10/1000 μs) - defines energy-handling capability for common lightning and inductive-switching transients |
| IR @ VWM | ≤50 μA - minimizes standby power loss and avoids false triggering in low-current signal paths |
| TJ max | +150 °C - supports under-hood automotive and industrial environments without derating |
| ESD rating | 15 kV air / 8 kV contact - exceeds IEC 61000-4-2 Level 4 for system-level ESD robustness |

Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|
Use Scenario: Protecting LIN/CAN transceiver inputs and analog sensor outputs (e.g., pressure, temperature) from load-dump and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and ground to clamp transients before they reach sensitive input stages of transceivers or ADC front-ends. Use Value: Prevents latch-up or permanent damage in automotive-grade microcontrollers and communication ICs while maintaining <50 μA leakage at 7.0 V. | Use Scenario: Shielding differential CAN H/L lines from electrostatic discharge and inductive switching noise in factory automation controllers. IC Role / Device Role / Timing Role: Paired TVS devices (one per line) referenced to common ground, providing symmetric clamping without affecting differential signaling integrity. Use Value: Enables compliance with ISO 11898-2 immunity requirements and maintains signal edge fidelity due to low capacitance (<15 pF at zero bias). |
| Consumer IoT Power Input | Medical Diagnostic Equipment Signal Lines |
Use Scenario: Safeguarding 5 V/3.3 V DC input rails of battery-powered smart home hubs against accidental AC coupling or hot-plug surges. IC Role / Device Role / Timing Role: Standoff-rated TVS placed upstream of LDO regulators and USB power switches to absorb short-duration overvoltage spikes. Use Value: Eliminates need for bulkier alternatives like varistors; 150 W rating handles >1000 μs surges without degradation across 10⁵+ events. | Use Scenario: Protecting analog front-end inputs of portable ultrasound or ECG units from ESD during clinical handling and cable coupling. IC Role / Device Role / Timing Role: Low-leakage TVS on biopotential amplifier inputs to preserve signal-to-noise ratio while meeting IEC 61000-4-2 Level 4. Use Value: Ensures diagnostic accuracy by limiting clamping voltage to 12.0 V and maintaining <50 μA reverse current at operating bias. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A-HF | DO-214AC (SMA) package; 2.5 mm height; higher RθJA (400 °C/W); same VWM/VBR range | Less suitable for ultra-low-profile designs; requires larger pad area and higher board clearance | Select when legacy SMA footprint exists or thermal budget allows higher junction rise |
| 1.5SMC7.0A-Q | DO-214AB (SMC) package; 2.3 mm height; 1500 W PPPM; higher VCL (12.7 V) | Better for high-energy surges but incompatible with space-constrained layouts | Choose only if system-level surge testing exceeds IEC 61000-4-5 Level 3 and board real estate permits larger footprint |
Compared with SMAJ7.0A-HF and 1.5SMC7.0A-Q, MSMP7.0AHM3/H delivers identical electrical protection performance in a 60% lower profile package with AEC-Q101 qualification-making it optimal for next-generation automotive and portable medical PCBs where height and reliability are critical.

FAQ
What is the maximum clamping voltage of the MSMP7.0AHM3/H at its rated peak pulse current?
The MSMP7.0AHM3/H has a maximum clamping voltage (VCL) of 12.0 V at 12.5 A peak pulse current (10/1000 μs waveform), measured per standard test conditions. This value ensures downstream ICs see limited overvoltage during transient events. The device achieves this with a dynamic resistance (RD) of 0.272 Ω, directly contributing to predictable voltage limiting behavior. Designers can rely on this spec for margin analysis in 7 V rail protection schemes.
Is MSMP7.0AHM3/H suitable for automotive applications?
Yes, MSMP7.0AHM3/H is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes halogen-free, RoHS-compliant materials, MSL Level 1 moisture sensitivity, and validated performance across -55 °C to +150 °C junction temperature. The "HM3" suffix denotes AEC-Q101 qualification, distinguishing it from commercial-grade M3 variants. It is widely deployed in automotive sensor modules, body control units, and infotainment interfaces.
What does the "HM3" suffix mean in MSMP7.0AHM3/H?
The "HM3" suffix in MSMP7.0AHM3/H indicates halogen-free, RoHS-compliant construction with full AEC-Q101 qualification. Unlike base "M3" parts (commercial grade), HM3 parts undergo additional stress testing-including extended temperature cycling, high-temperature operating life, and ESD validation-to meet automotive reliability standards. This suffix is defined in Vishay's ordering information table and confirmed in the mechanical data section of document 89457.
Can MSMP7.0AHM3/H be used in bidirectional configurations?
No, MSMP7.0AHM3/H is unidirectional only, as clearly stated in the Features section and electrical characteristics table. It must be installed with cathode toward the protected line and anode to ground. For bidirectional protection, Vishay offers separate part numbers such as SMBJ7.0CA or SMCJ7.0CA. Using MSMP7.0AHM3/H in reverse orientation will not provide symmetrical clamping and may fail to protect against positive-going transients.
What is the recommended PCB pad layout for MSMP7.0AHM3/H?
Vishay specifies a minimum recommended pad layout with 6.0 mm × 6.0 mm copper pads per terminal for thermal performance and surge current handling. The datasheet states that ratings assume mounting on these pads; using smaller pads degrades both power dissipation (derating PD from 1.0 W to 0.5 W) and peak pulse current capability. The MicroSMP outline drawing (page 4) provides exact dimensions: 2.30 mm × 1.10 mm body with 0.73 mm × 0.63 mm pad extensions.
