Product details
Overview
MSMP6.5A-M3/89A from Vishay General Semiconductor is a unidirectional surface-mount TRANSZORB® transient voltage suppressor in 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 - used to protect MOSFETs and sensor signal lines from inductive switching transients and ESD.
For engineers reviewing the MSMP6.5A-M3/89A datasheet, MSMP6.5A-M3/89A pinout, MSMP6.5A-M3/89A application, or MSMP6.5A-M3/89A equivalent, key selection criteria include clamping voltage (11.2 V max at 13.4 A), low-profile height (0.65 mm), MSL Level 1 rating, and halogen-free RoHS-compliant construction for automotive and industrial PCB layouts.
Technical Context
This TVS diode employs an oxide planar chip junction and unidirectional polarity, optimized for fast response to transient overvoltages induced by inductive load switching or lightning surges. Its thermal resistance is 250 °C/W (junction-to-ambient) and 30 °C/W (junction-to-mount), enabling reliable operation up to 150 °C junction temperature.
Designed for automated placement, it features matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102, and passes JESD 201 Class 2 whisker testing. The cathode is marked by a color band, and the device meets IEC 61000-4-2 ESD immunity (15 kV air / 8 kV contact).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum reverse stand-off voltage before conduction begins; ensures no leakage during normal 6.5 V rail operation |
| VBR (min/max) | 7.22 V / 7.98 V at 10 mA - precise breakdown threshold defining turn-on consistency across production lots |
| VCL (max) | 11.2 V at 13.4 A (10/1000 μs) - clamping voltage limits stress on downstream ICs during surge events |
| PPPM | 150 W (10/1000 μs) - peak pulse power handling capability for standard lightning/surge waveforms |
| TJ max | +150 °C - maximum operating junction temperature supports under-hood automotive environments |
| ESD Rating | 15 kV (air), 8 kV (contact) - exceeds IEC 61000-4-2 Level 4 for system-level ESD robustness |
| Package | MicroSMP (DO-219AD) - 0.65 mm profile enables high-density routing and compatibility with fine-pitch SMT assembly |
Pinout & Package
MicroSMP (DO-219AD) is a two-terminal surface-mount package with cathode identified by a visible color band. Dimensions: 2.70 mm × 1.40 mm × 0.65 mm (L × W × H). Mounting requires 6.0 mm × 6.0 mm copper pads per terminal for rated power dissipation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.5A | DO-214AC (SMA) package; 2.5 mm height; 400 W PPPM; higher VCL (11.5 V) | Less space-constrained designs; higher surge margin but larger footprint | Select when board area permits and higher single-pulse energy handling is required |

FAQ
What is the clamping voltage of the MSMP6.5A-M3/89A at its rated peak pulse current?
The MSMP6.5A-M3/89A 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 surge conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The MSMP6.5A-M3/89A maintains this clamping performance consistently across its operating temperature range and lifetime, supporting robust system-level surge immunity.
Is the MSMP6.5A-M3/89A suitable for automotive applications?
Yes, the MSMP6.5A-M3/89A is AEC-Q101 qualified and rated for operation from −55 °C to +150 °C, making it suitable for under-hood and cabin automotive applications. Its MicroSMP package, MSL Level 1 rating, and validated ESD performance (8 kV contact / 15 kV air) align with automotive electronics requirements. The MSMP6.5A-M3/89A is commonly deployed in ADAS sensor interfaces, body control modules, and infotainment I/O protection.
What does the "M3" suffix indicate in MSMP6.5A-M3/89A?
The "M3" suffix in MSMP6.5A-M3/89A denotes halogen-free, RoHS-compliant construction and commercial-grade qualification. It distinguishes the part from the "HM3" variant, which adds AEC-Q101 qualification. Both share identical electrical specs and MicroSMP packaging, but only HM3 is certified for automotive use. The MSMP6.5A-M3/89A remains fully compatible with industrial and consumer applications requiring environmental compliance without automotive validation.
How does the MSMP6.5A-M3/89A compare to standard SMA-package TVS diodes in terms of board space?
The MSMP6.5A-M3/89A occupies approximately 35 % less board area than DO-214AC (SMA) devices like SMAJ6.5A and achieves a 0.65 mm height versus 2.5 mm - reducing overall module thickness significantly. Its 2.70 mm × 1.40 mm footprint fits tightly routed high-density PCBs where vertical clearance is limited. The MSMP6.5A-M3/89A thus enables miniaturization in space-critical applications such as wearable sensors and compact ECUs without sacrificing surge rating.
What is the recommended PCB pad layout for optimal thermal and electrical performance of the MSMP6.5A-M3/89A?
Vishay specifies 6.0 mm × 6.0 mm copper pads per terminal for rated 150 W pulse power dissipation and thermal management. These pads must be connected to internal ground planes via multiple thermal vias to achieve the specified RθJM of 30 °C/W. The MSMP6.5A-M3/89A datasheet provides exact pad dimensions and solder mask clearance guidance; deviating from this layout reduces surge capability and may cause premature failure under repeated transients.
