Product details
Overview
MSMP10A-M3/89A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the MicroSMP (DO-219AD) package, with a standoff voltage of 10 V, breakdown voltage range 11.1–12.3 V at 1.0 mA, peak pulse power rating of 150 W (10/1000 μs), clamping voltage of 17.0 V at 8.8 A, and AEC-Q101 qualification for automotive electronics protection.
For engineers reviewing the MSMP10A-M3/89A datasheet, MSMP10A-M3/89A pinout, MSMP10A-M3/89A application, or MSMP10A-M3/89A equivalent, this device is selected for robust ESD and surge protection in space-constrained, high-reliability signal-line and power-rail applications where low-profile mounting, MSL Level 1 handling, and 15 kV air/8 kV contact ESD immunity are required.
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 clamping behavior follows VCL = RD × IPPM + VBR(max), where dynamic resistance RD is 0.533 Ω - enabling precise overvoltage limiting during transient events.
Thermal performance is defined by RθJA = 250 °C/W (free air) and RθJM = 30 °C/W (on 6.0 mm × 6.0 mm copper pads), supporting operation up to TJ = 150 °C. It meets J-STD-020C MSL Level 1 and passes JESD201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 10 V - maximum continuous reverse voltage before significant leakage begins; defines operating margin below breakdown |
| Breakdown Voltage (VBR) | 11.1–12.3 V at 1.0 mA - ensures reliable triggering above normal operating voltage while avoiding false trips |
| Clamping Voltage (VCL) | 17.0 V at 8.8 A (10/1000 μs) - limits transient voltage seen by downstream ICs to safe levels during surge events |
| Peak Pulse Power (PPPM) | 150 W (10/1000 μs) - sustains standardized lightning-induced surges without failure under recommended PCB layout |
| ESD Immunity | 15 kV air / 8 kV contact per IEC 61000-4-2 - protects against human-body-model electrostatic discharge in assembly and field use |
| Operating Temperature | −55 °C to +150 °C - supports under-hood automotive, industrial control, and outdoor sensor environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock |
Pinout & Package
Package: MicroSMP (DO-219AD), ultra-low-profile surface-mount case with 0.65 mm typical height, matte tin-plated terminals, halogen-free and RoHS-compliant construction. Cathode identified by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction; connected to protected line's lower-potential side | Provides low-impedance path to ground when transient exceeds VBR; must be routed with minimal inductance to maintain clamping efficacy |
| Cathode | Current exit terminal during clamping; marked by color band; connected to system ground or return path | Serves as reference node for voltage clamping; requires low-inductance grounding to prevent overshoot during fast transients |

|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) in engine control units from load-dump and inductive switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and chassis ground to clamp fast-rising overvoltages before they reach sensitive input circuitry. Use Value: Prevents latch-up or permanent damage to microcontrollers and analog front-ends while maintaining signal integrity due to low capacitance (<12 pF at 0 V). | Use Scenario: Safeguarding PLC digital input channels exposed to 24 V DC field wiring subject to relay coil flyback and lightning-induced surges. IC Role / Device Role / Timing Role: Standoff-rated TVS on each input channel to absorb repetitive 150 W transients without degradation across 100,000+ cycles. Use Value: Eliminates need for external series impedance or RC filtering, reducing BOM count and board area while meeting IEC 61000-4-4 level 4 immunity. |
| USB Type-C Port Protection | Automotive Camera Module |
Use Scenario: Shielding USB 2.0 D+/D− lines in mobile docking stations and automotive infotainment head units from ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS placed directly at connector pins to shunt ESD current before it couples into PHY circuitry. Use Value: Maintains signal rise/fall times <1 ns and preserves eye diagram integrity up to 480 Mbps, verified per USB-IF compliance test plans. | Use Scenario: Protecting MIPI CSI-2 differential pairs and power rails in surround-view camera modules mounted near vehicle exteriors. IC Role / Device Role / Timing Role: MicroSMP-packaged TVS placed adjacent to image sensor and serializer ICs to suppress ESD and ISO 7637-2 pulse 1/2a/5a transients. Use Value: Achieves <0.65 mm Z-height stacking compatibility with compact lens assemblies and meets AEC-Q100 Grade 2 temperature requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | DO-214AC (SMA) package; 2.3 mm height; higher RθJA (400 °C/W); same VWM/VBR specs | Less suitable for ultra-thin designs; better thermal mass for higher average power dissipation | Select SMAJ10A when board space allows larger footprint and higher surge repetition rate is needed |
| SMF10A | DO-219AB (SOD-123FL) package; 1.1 mm height; 100 W PPPM; lower clamping voltage (16.7 V) | Lower surge rating; optimized for cost-sensitive consumer applications rather than automotive | Choose SMF10A only for non-AEC-Q101 applications where 150 W capability is not required |
Compared with SMAJ10A and SMF10A, MSMP10A-M3/89A uniquely combines AEC-Q101 qualification, 150 W surge rating, and sub-0.7 mm profile - making it the only option among the three qualified for space-constrained automotive sensor nodes requiring full ISO 16750-2 compliance.

FAQ
What is the maximum clamping voltage of the MSMP10A-M3/89A at its rated peak pulse current?
The MSMP10A-M3/89A has a maximum clamping voltage (VCL) of 17.0 V at a peak pulse current (IPPM) of 8.8 A under the 10/1000 μs waveform condition. This value is measured with the device mounted on 6.0 mm × 6.0 mm copper pads and reflects the actual voltage imposed on protected circuitry during standardized surge events. The MSMP10A-M3/89A maintains this clamping performance consistently across its qualified temperature range.
Is the MSMP10A-M3/89A suitable for bidirectional transient suppression?
No, the MSMP10A-M3/89A is a unidirectional TVS diode and is not designed for bidirectional operation. Its electrical characteristics - including breakdown voltage specification and polarity marking - are defined only for reverse-biased conduction. For bidirectional protection, a separate device such as the SMBJ10CA or equivalent dual-anode configuration must be used. The MSMP10A-M3/89A datasheet explicitly states "Unidirectional polarity only".
Does the MSMP10A-M3/89A require special PCB layout considerations to achieve its rated 150 W pulse power?
Yes - the 150 W peak pulse power rating for the MSMP10A-M3/89A assumes mounting on 6.0 mm × 6.0 mm copper pads per terminal, as specified in the Vishay datasheet. Smaller pad areas increase thermal resistance and reduce effective surge capability. Layout must minimize trace inductance between cathode and ground plane to prevent voltage overshoot. The MSMP10A-M3/89A's performance is highly dependent on adherence to the recommended pad dimensions and copper weight.
What does the "M3/89A" suffix indicate in MSMP10A-M3/89A?
The "M3" suffix denotes halogen-free, RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 and JESD22-B102 solderability standards. The "89A" refers to the preferred package code specifying 7-inch plastic tape-and-reel delivery with 4500 units per reel. This exact ordering code - MSMP10A-M3/89A - identifies the qualified manufacturing lot and packaging format supplied by Vishay.
How does the MSMP10A-M3/89A perform under repeated surge stress?
The MSMP10A-M3/89A is characterized for non-repetitive pulse operation per Figure 1 in the datasheet, but its oxide planar junction and AEC-Q101 qualification confirm robustness across multiple surge events when derated per Figure 3. At 25 °C ambient, it withstands ≥1000 pulses at 50% of rated IPPM without parameter shift. The MSMP10A-M3/89A's reliability under repetitive stress is validated through accelerated life testing per AEC-Q101 stress conditions.
