Product details
Overview
MSP5.0A-M3/89A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the MicroSMP (DO-219AD) package, rated for 5.0 V stand-off voltage, 6.40–7.07 V breakdown at 10 mA, 150 W peak pulse power (10/1000 μs), and 9.2 V maximum clamping voltage at 16.3 A. It protects MOSFETs and sensor signal lines against inductive switching transients and ESD events in automotive and industrial control modules.
For engineers reviewing the MSP5.0A-M3/89A datasheet, MSP5.0A-M3/89A pinout, MSP5.0A-M3/89A application, or MSP5.0A-M3/89A equivalent, key selection criteria include clamping voltage at rated IPPM, unidirectional polarity, AEC-Q101 qualification, MicroSMP footprint compatibility, and 15 kV air/8 kV contact ESD immunity per IEC 61000-4-2.
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 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 under defined PCB pad layouts.
The device delivers 150 W peak pulse power with a 10/1000 μs waveform when mounted on 6.0 mm × 6.0 mm copper pads, and exhibits 0.131 Ω dynamic resistance-critical for low-voltage overshoot during transient suppression. It meets MSL Level 1 per J-STD-020C and passes JESD 201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum reverse voltage before significant leakage; sets operating margin below breakdown for IC/sensor line protection. |
| VBR (min/max) | 6.40 V / 7.07 V at 10 mA - Confirmed breakdown range ensures predictable turn-on during overvoltage events. |
| VCL @ IPPM | 9.2 V at 16.3 A (10/1000 μs) - Clamping voltage directly limits stress on downstream components like microcontrollers or gate drivers. |
| PPPM | 150 W - Peak surge energy handling capacity under standardized transient waveform, validated with 6 mm × 6 mm copper pads. |
| IR @ VWM | 100 μA - Low reverse leakage preserves signal integrity and battery life in always-on sensor interfaces. |
| ESD Rating | 15 kV air / 8 kV contact - Meets IEC 61000-4-2 system-level ESD immunity requirements for automotive and industrial end equipment. |
| TJ max. | 150 °C - Enables use in under-hood automotive modules and high-temperature industrial enclosures without derating. |
Pinout & Package
Package: MicroSMP (DO-219AD), ultra-low-profile surface-mount case with 0.65 mm typical height, halogen-free, RoHS-compliant, and qualified to AEC-Q101. Matte tin-plated terminals meet J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction; connected to protected line's ground reference side in unidirectional configuration. | Completes clamping path to ground when transient exceeds VBR; requires direct low-inductance connection to system GND plane. |
| Cathode | Current exit terminal during clamping; marked by color band; connects to protected signal or power line. | Defines polarity-sensitive placement-reversal prevents clamping action and risks catastrophic failure under overvoltage. |
Key Features
| Feature | Design Value |
|---|---|
| MicroSMP footprint | 0.106" × 0.055" (2.70 mm × 1.40 mm) outline enables high-density layout in space-constrained automotive ECUs and IoT sensor nodes. |
| AEC-Q101 qualification | Validated reliability for automotive applications including engine control, body electronics, and ADAS sensor interfaces. |
| Low clamping dynamic resistance | 0.131 Ω ensures minimal voltage overshoot during 16.3 A transients-critical for protecting 5 V logic rails and analog front-ends. |
| MSL Level 1 rating | Allows unlimited floor life and reflow up to 260 °C peak, simplifying SMT assembly without baking or special handling. |
| 15 kV air discharge ESD immunity | Exceeds IEC 61000-4-2 Level 4 requirements, reducing need for secondary board-level protection in harsh environments. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|

Use Value: Preserves 480 Mbps USB signaling integrity while meeting IEC 61000-4-2 Level 4 compliance without sacrificing data rate. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | DO-214AC (SMA) package; 2.2 mm height; higher RθJA (350 °C/W); same VWM/VBR/VCL specs. | Larger footprint and lower power density limit use in ultra-thin modules; less suitable for automated placement on fine-pitch boards. | Select SMAJ5.0A only if legacy SMA layout exists or thermal constraints allow larger pad area. |
| SMF5.0A | DO-219AB (SOD-123FL) package; 1.2 mm width; 0.9 mm height; slightly higher VCL (9.6 V at 15.4 A). | Smaller 0.047" × 0.022" footprint than MicroSMP but lower peak power (100 W); not AEC-Q101 qualified. | Choose SMF5.0A for cost-sensitive consumer designs where AEC-Q101 and 150 W rating are not required. |
Compared with SMAJ5.0A and SMF5.0A, MSP5.0A-M3/89A offers the smallest height (0.65 mm), highest power density (150 W in MicroSMP), and automotive-grade qualification-making it optimal for next-gen compact, high-reliability systems where board space and environmental ruggedness are critical.

FAQ
What is the maximum clamping voltage of MSP5.0A-M3/89A at its rated peak pulse current?
The MSP5.0A-M3/89A has a maximum clamping voltage (VCL) of 9.2 V at 16.3 A peak pulse current with a 10/1000 μs waveform. This value is measured under standard test conditions with the device mounted on 6.0 mm × 6.0 mm copper pads. The clamping performance ensures downstream 5 V logic components remain within safe operating limits during transient events. The MSP5.0A-M3/89A achieves this with a dynamic resistance of 0.131 Ω, minimizing voltage overshoot beyond VBR.
Is MSP5.0A-M3/89A suitable for automotive applications?
Yes, MSP5.0A-M3/89A is AEC-Q101 qualified and rated for operation from −55 °C to +150 °C junction temperature, making it suitable for under-hood and cabin-mounted automotive electronics. Its MicroSMP package supports automated placement in high-volume ECU manufacturing, and its 15 kV air/8 kV contact ESD rating meets IEC 61000-4-2 requirements for vehicle subsystems. The MSP5.0A-M3/89A is explicitly designated for automotive-grade use in Vishay's ordering nomenclature (M3 suffix = industrial grade; HM3 = automotive grade-but M3 itself is AEC-Q101 qualified per datasheet).
What does the "M3" suffix indicate in MSP5.0A-M3/89A?
The "M3" suffix in MSP5.0A-M3/89A denotes halogen-free, RoHS-compliant construction with matte tin-plated terminals that pass JESD 201 Class 2 whisker testing. It signifies industrial-grade qualification and compatibility with lead-free reflow profiles up to 260 °C peak temperature. The "89A" refers to the 7-inch plastic tape-and-reel packaging format containing 4500 units. The M3 designation confirms the MSP5.0A-M3/89A meets material and process requirements for long-term reliability in commercial and industrial environments.
Can MSP5.0A-M3/89A be used in bidirectional configurations?
No, MSP5.0A-M3/89A is strictly unidirectional and must be oriented with the cathode band toward the protected line. It lacks symmetrical breakdown characteristics and will not clamp reverse-polarity transients. For bidirectional protection, Vishay offers separate dual-diode configurations such as the SMBJ5.0CA. Using MSP5.0A-M3/89A in reverse orientation results in no clamping action and potential device failure under overvoltage. Always verify polarity alignment during PCB layout and assembly of the MSP5.0A-M3/89A.
What is the thermal resistance of MSP5.0A-M3/89A, and how does it affect layout?
The MSP5.0A-M3/89A has a junction-to-ambient thermal resistance (RθJA) of 250 °C/W and a junction-to-mount resistance (RθJM) of 30 °C/W when mounted on 6.0 mm × 6.0 mm copper pads. To maintain safe operation at full 150 W pulse rating, PCB layout must provide adequate copper area per terminal-minimum recommended pad dimensions are specified in the datasheet. Insufficient copper reduces heat dissipation and may cause thermal runaway during repeated surges. The MSP5.0A-M3/89A's low profile demands precise thermal pad design to avoid exceeding 150 °C junction temperature.
