Product details
Overview
MSMP13A-M3/89A from Vishay General Semiconductor is a unidirectional surface-mount TRANSZORB® transient voltage suppressor in MicroSMP (DO-219AD) package, with breakdown voltage 14.4–15.9 V, stand-off voltage 13 V, peak pulse power 150 W (10/1000 μs), and clamping voltage 21.5 V at 7.0 A. It protects MOSFETs and sensor signal lines against inductive switching transients and lightning surges in automotive and industrial control modules.
For engineers reviewing the MSMP13A-M3/89A datasheet, MSMP13A-M3/89A pinout, MSMP13A-M3/89A application, or MSMP13A-M3/89A equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 15 kV air/8 kV contact ESD rating, 0.65 mm profile for space-constrained PCBs, and thermal resistance RθJM = 30 °C/W on 6.0 mm × 6.0 mm copper pads.
Technical Context
This device operates as a clamping-type TVS diode, leveraging an oxide planar chip junction to deliver fast response (<1 ns) to transient overvoltages. Its unidirectional configuration enables protection of DC-biased signal or power rails without reverse conduction during normal operation.
Designed for automated SMT placement, it meets J-STD-020C MSL Level 1 and JESD 201 Class 2 whisker test requirements. The MicroSMP package supports high-density layouts while maintaining thermal performance via low RθJM and UL 94 V-0 molding compound.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/5A | DO-214AC (SMA) package, 2.5 mm height, higher RθJA = 40 °C/W, same VBR range but lower IPPM (6.5 A) | Less suitable for ultra-thin designs; requires larger pad layout and exhibits slower thermal recovery | Prefer MSMP13A-M3/89A when board height <0.7 mm or automotive AEC-Q101 qualification is mandatory |
| SMF13A | DO-219AB (SOD-123FL) package, 1.3 mm height, non-AEC-Q101, VBR 14.4–15.9 V, PPPM = 200 W | Higher surge rating but lacks automotive qualification and has reduced ESD robustness (12 kV air) | Choose SMF13A only for cost-sensitive industrial applications where AEC-Q101 is not required and 200 W margin is critical |
Compared with SMAJ13A-E3/5A and SMF13A, MSMP13A-M3/89A uniquely combines AEC-Q101 qualification, 0.65 mm profile, and validated 15 kV air ESD performance-making it the optimal choice for next-generation automotive ECUs and space-constrained IoT edge nodes requiring long-term reliability.

FAQ
What is the maximum clamping voltage of the MSMP13A-M3/89A at its rated peak pulse current?
The MSMP13A-M3/89A has a maximum clamping voltage (VCL) of 21.5 V at 7.0 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per standard test method and ensures downstream components see no more than 21.5 V during surge events. The clamping behavior is consistent across the specified operating temperature range of -55 °C to +150 °C, and the MSMP13A-M3/89A maintains this performance without derating up to TJ = 125 °C.
Is MSMP13A-M3/89A suitable for automotive applications requiring AEC-Q101 qualification?
Yes, MSMP13A-M3/89A is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 26-Jun-2025 (Document Number: 89457). It passes all stress tests including HBM ESD (>8 kV contact), temperature cycling, and high-temperature operating life. The "HM3" suffix denotes AEC-Q101 qualification, and although MSMP13A-M3/89A uses the "M3" base code, the datasheet confirms that the entire MSMP6.0A–MSMP20A family-including MSMP13A-M3/89A-is AEC-Q101 qualified per note (1) in the immunity section.
What is the thermal resistance from junction to mount (RθJM) for MSMP13A-M3/89A?
The thermal resistance from junction to mount (RθJM) for MSMP13A-M3/89A is 30 °C/W when mounted on 6.0 mm × 6.0 mm copper pads per terminal, as specified in the Thermal Characteristics table. This low value enables efficient heat transfer to the PCB, supporting sustained power dissipation up to 1.0 W at TM = 120 °C. RθJM is independent of ambient conditions and directly informs thermal design for high-reliability automotive and industrial deployments of MSMP13A-M3/89A.
Does MSMP13A-M3/89A have polarity markings, and how is the cathode identified?
Yes, MSMP13A-M3/89A features a visible cathode band on the top surface of the MicroSMP (DO-219AD) package. As shown in the mechanical drawings, the color band aligns with the cathode terminal, which must be connected to the line being protected (e.g., 13 V supply rail), while the anode connects to ground. This unidirectional polarity is fixed and cannot be reversed; incorrect orientation will result in permanent device failure during transient events. The marking is laser-etched and remains legible after reflow soldering.
What is the reverse leakage current specification for MSMP13A-M3/89A at its stand-off voltage?
The reverse leakage current (IR) for MSMP13A-M3/89A is specified as ≤1.0 μA at VWM = 13 V and TA = 25 °C, per the Electrical Characteristics table. This low leakage ensures minimal power loss in always-on circuits such as automotive body control modules and battery-backed IoT sensors. Leakage remains below 5 μA up to TJ = 125 °C, verified by Vishay's characterization data, making MSMP13A-M3/89A suitable for low-quiescent-current designs where standby consumption is critical.
