Overview
MSMP6.5AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the MicroSMP (DO-219AD) package, with 6.5 V stand-off voltage (VWM), 7.22–7.98 V breakdown voltage (VBR), 150 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive electronics protection.
For engineers reviewing the MSMP6.5AHM3/H datasheet, MSMP6.5AHM3/H pinout, MSMP6.5AHM3/H application, or MSMP6.5AHM3/H equivalent, key selection criteria include clamping voltage (11.2 V max at 13.4 A), low-profile height (0.65 mm), ESD robustness (15 kV air / 8 kV contact), and compatibility with automated SMT assembly on 6.0 mm × 6.0 mm copper pads.
Technical Context
This TVS diode uses an oxide planar chip junction and unidirectional polarity to clamp transient overvoltages before they damage downstream ICs or MOSFETs. Its design targets fast response to inductive switching surges and lightning-induced transients while maintaining low leakage (<100 μA at VWM) and stable thermal performance up to 150 °C junction temperature.
The MicroSMP package enables high-density PCB layouts with minimal board space and supports reflow soldering per J-STD-002 and JESD 22-B102. It meets MSL Level 1 and passes JESD 201 Class 2 whisker testing, confirming suitability for automotive-grade production environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.5A-Q | DO-214AC (SMA) package; larger footprint (4.5 mm × 2.7 mm), higher RθJA (50°C/W vs. 250°C/W), same VWM/VBR specs. | Less suitable for high-density automotive PCBs; better for industrial boards with thermal relief constraints. | Select SMAJ6.5A-Q only if board layout cannot accommodate MicroSMP's 2.3 mm × 1.1 mm outline or requires higher single-pulse energy margin. |
| SMF6.5A | DO-219AB (SOD-123FL) package; same height (0.65 mm) but wider (1.7 mm), slightly lower PPPM (100 W), identical AEC-Q101 qualification. | Marginally lower surge handling; acceptable for non-critical sensor lines or secondary protection stages. | Choose SMF6.5A when cost sensitivity outweighs need for full 150 W rating, or when existing SOD-123FL footprints are reused. |

FAQ
What is the maximum clamping voltage of MSMP6.5AHM3/H at its rated peak pulse current?
The MSMP6.5AHM3/H has a maximum clamping voltage (VCL) of 11.2 V at 13.4 A peak pulse current (10/1000 μs waveform). This value is measured under standardized test conditions and ensures protected circuits remain below safe voltage thresholds during surge events. The dynamic resistance (RD) of 0.240 Ω contributes to this low clamping performance. MSMP6.5AHM3/H maintains this specification across its qualified operating temperature range.
Is MSMP6.5AHM3/H suitable for use in automotive applications requiring AEC-Q101 qualification?
Yes, MSMP6.5AHM3/H is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet revision dated 26-Jun-2025. It undergoes stress testing per AEC-Q101-001 for human-body-model ESD (>8 kV contact), temperature cycling, and mechanical shock. The "HM3" suffix denotes AEC-Q101 qualification, halogen-free composition, and RoHS compliance-making MSMP6.5AHM3/H appropriate for engine control, ADAS, and body electronics.
What is the thermal resistance of MSMP6.5AHM3/H, and how does it affect PCB layout?
The MSMP6.5AHM3/H has a typical junction-to-ambient thermal resistance (RθJA) of 250 °C/W when mounted on minimum recommended pad layout, and 30 °C/W junction-to-mount (RθJM) when using 6.0 mm × 6.0 mm copper pads per terminal. To achieve optimal thermal performance, PCB layout must follow Vishay's recommended pad dimensions and copper area. MSMP6.5AHM3/H relies on copper mass-not airflow-for heat dissipation, so thermal vias and solid ground planes directly under the package enhance reliability.
Does MSMP6.5AHM3/H have polarity, and how is it identified on the device?
Yes, MSMP6.5AHM3/H is unidirectional and features explicit polarity marking: a color band on the cathode end. The device must be oriented with the banded end connected to the line being protected (e.g., sensor supply or signal trace), and the anode connected to ground. Incorrect orientation prevents proper clamping and may result in catastrophic failure during surge events. MSMP6.5AHM3/H is not interchangeable with bidirectional TVS diodes without circuit redesign.
What are the soldering requirements for MSMP6.5AHM3/H during reflow assembly?
MSMP6.5AHM3/H is rated for MSL Level 1 per J-STD-020C and supports peak reflow temperatures up to 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 for solderability. Standard lead-free reflow profiles (e.g., IPC/JEDEC J-STD-020) apply. No pre-baking is required due to MSL Level 1 classification, and MSMP6.5AHM3/H passes JESD 201 Class 2 whisker testing-ensuring long-term interconnect integrity.
