Vishay General Semiconductor - Diodes Division MSMP6.0A-M3/89A

Overview

MSMP6.0A-M3/89A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in the MicroSMP (DO-219AD) package, with 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR), 150 W peak pulse power (10/1000 μs), and AEC-Q101 qualification. It protects MOSFETs and sensor signal lines against inductive switching transients and lightning-induced surges in automotive and industrial control modules.

For engineers reviewing the MSMP6.0A-M3/89A datasheet, MSMP6.0A-M3/89A pinout, MSMP6.0A-M3/89A application, or MSMP6.0A-M3/89A equivalent, key selection criteria include clamping voltage (10.3 V at 14.6 A), low-profile height (0.65 mm), MSL Level 1 rating, ESD robustness (15 kV air / 8 kV contact), and halogen-free RoHS-compliant construction.

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 transient suppression behavior follows the 10/1000 μs double-exponential waveform standard, delivering precise clamping via a defined dynamic resistance (RD = 0.201 Ω).

Thermal performance is characterized by RθJM = 30 °C/W when mounted on 6.0 mm × 6.0 mm copper pads, enabling reliable operation up to TJ = 150 °C. It meets JESD201 Class 2 whisker resistance and J-STD-020C reflow profile (peak 260 °C).

FAQ

What is the clamping voltage of the MSMP6.0A-M3/89A at its rated peak pulse current?

The MSMP6.0A-M3/89A has a maximum clamping voltage (V_CL) of 10.3 V at 14.6 A peak pulse current (I_PPM) under the 10/1000 μs waveform condition. This value is measured per the standard test method in Vishay's datasheet (Document Number: 89457), and directly determines the maximum voltage imposed on protected circuitry during a surge event. The MSMP6.0A-M3/89A achieves this clamping performance using a dynamic resistance (R_D) of 0.201 Ω, ensuring predictable and repeatable protection behavior.

Is the MSMP6.0A-M3/89A suitable for automotive applications?

Yes, the MSMP6.0A-M3/89A is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its qualification covers temperature cycling, humidity testing, mechanical shock, and ESD robustness per AEC-Q101-001 (H3B class >8 kV contact). The MSMP6.0A-M3/89A also meets JESD201 Class 2 whisker resistance and J-STD-020C reflow profiles-critical for under-hood reliability.

What does the "M3" suffix indicate in MSMP6.0A-M3/89A?

The "M3" suffix in MSMP6.0A-M3/89A denotes halogen-free, RoHS-compliant construction and commercial-grade qualification. It distinguishes the part from the "HM3" variant (AEC-Q101 qualified with identical packaging and electrical specs). The "89A" refers to the preferred tape-and-reel packaging code: 7-inch diameter plastic tape, 4500 units per reel. The MSMP6.0A-M3/89A is not automotive-qualified unless specified as HM3.

How does the MicroSMP (DO-219AD) package of the MSMP6.0A-M3/89A compare to SMA or SOD-123FL?

The MicroSMP (DO-219AD) package of the MSMP6.0A-M3/89A measures 2.70 mm × 2.30 mm × 0.65 mm-significantly smaller than SMA (DO-214AC, 4.5 mm × 2.7 mm × 1.75 mm) and slightly more compact than SOD-123FL (DO-219AB, 2.7 mm × 1.7 mm × 0.65 mm). Unlike SOD-123FL, MicroSMP offers symmetric pad layout and optimized thermal path to mounting pads. The MSMP6.0A-M3/89A leverages this for R_θJM = 30 °C/W, outperforming many legacy packages in thermal dissipation per unit area.

Does the MSMP6.0A-M3/89A support automated optical inspection (AOI) after reflow?

Yes, the MSMP6.0A-M3/89A supports AOI due to its well-defined top-surface geometry, consistent matte tin plating, and visible cathode band marking. Its MicroSMP package exhibits high contrast between the dark-mold compound and silkscreen-compatible terminal finish, enabling reliable detection of solder joint quality, polarity orientation, and placement accuracy. The MSMP6.0A-M3/89A is explicitly designed for high-yield automated placement and post-reflow inspection in Tier 1 automotive manufacturing lines.
