Product details
Overview
MSMP11A-M3/89A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the MicroSMP (DO-219AD) package, featuring a breakdown voltage of 12.2–13.5 V at 1.0 mA, stand-off voltage of 11 V, peak pulse power of 150 W (10/1000 μs), and clamping voltage of 18.2 V at 8.2 A. It is AEC-Q101 qualified and used for ESD and surge protection on signal lines in automotive sensor units.
For engineers reviewing the MSMP11A-M3/89A datasheet, MSMP11A-M3/89A pinout, MSMP11A-M3/89A application, or MSMP11A-M3/89A equivalent, key selection criteria include unidirectional polarity, 150 W surge capability, 11 V working voltage, MicroSMP footprint compatibility, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This TVS diode uses an oxide planar chip junction and operates as a clamping device during transient overvoltage events. Its unidirectional configuration provides reverse-biased protection only, with a typical thermal resistance of 30 °C/W (junction-to-mount) when soldered to 6.0 mm × 6.0 mm copper pads.
The device meets IEC 61000-4-2 ESD immunity (15 kV air / 8 kV contact) and is rated for operation from –55 °C to +150 °C junction temperature. It is halogen-free, RoHS-compliant, and qualified to AEC-Q101 for automotive applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | DO-214AC (SMA) package; 2.3 mm height; 150 W rating; VBR = 12.2–13.5 V; same electrical specs but larger footprint | Less suitable for ultra-thin modules; higher thermal resistance (RθJA ≈ 50 °C/W vs. 250 °C/W for MSMP11A-M3/89A) | Select SMAJ11A only if board space allows larger package and legacy SMA footprints are already established. |
| SMF11A | DO-219AB (SOD-123FL) package; 1.1 mm height; 200 W rating; VBR = 12.2–13.5 V; slightly higher clamping (19.0 V @ 7.9 A) | Better surge margin but higher VC; not AEC-Q101 qualified; lower ESD rating (12 kV air) | Choose SMF11A for cost-sensitive industrial designs where AEC-Q101 is not required and 200 W headroom is preferred. |
Compared with SMAJ11A and SMF11A, MSMP11A-M3/89A delivers the lowest profile (0.65 mm), AEC-Q101 qualification, and optimized thermal mounting via MicroSMP's low RθJM (30 °C/W), making it the preferred choice for next-generation automotive and space-constrained industrial modules requiring validated reliability.

FAQ
What is the polarity configuration of the MSMP11A-M3/89A?
The MSMP11A-M3/89A is a unidirectional TVS diode, meaning it conducts only in reverse bias during overvoltage events. Its cathode is marked by a visible color band on the MicroSMP package body. This configuration protects against negative-going transients on grounded-signal architectures and is not suitable for bidirectional AC line protection without external circuitry.
Does the MSMP11A-M3/89A meet automotive qualification standards?
Yes, the MSMP11A-M3/89A is AEC-Q101 qualified, as confirmed in the Vishay datasheet (Document Number: 89457). It undergoes stress testing for temperature cycling, mechanical shock, humidity, and ESD per AEC-Q101-001, making it suitable for under-hood and chassis-mounted automotive applications.
What is the maximum clamping voltage of the MSMP11A-M3/89A under surge conditions?
The MSMP11A-M3/89A has a maximum clamping voltage (VC) of 18.2 V at 8.2 A for a 10/1000 μs waveform. This value is measured per standard test conditions and ensures protected downstream components see no more than 18.2 V during defined surge events.
Can the MSMP11A-M3/89A be used in high-humidity environments?
Yes - the MSMP11A-M3/89A uses a molding compound rated UL 94 V-0 and passes JESD22-A112 humidity testing as part of its AEC-Q101 qualification. Its matte tin-plated terminals also comply with JESD 22-B102 for solderability after exposure to humid conditions.
What is the thermal resistance of the MSMP11A-M3/89A when mounted on a PCB?
When mounted on 6.0 mm × 6.0 mm copper pads per the recommended layout, the MSMP11A-M3/89A has a junction-to-mount thermal resistance (RθJM) of 30 °C/W. Its junction-to-ambient resistance (RθJA) is 250 °C/W under free-air conditions, emphasizing the importance of proper pad design for thermal management.
