Product details
Overview
MSMP14A-M3/89A from Vishay General Semiconductor is a unidirectional surface-mount TRANSZORB® transient voltage suppressor in MicroSMP (DO-219AD) package, with breakdown voltage 15.6–17.2 V, stand-off voltage 14 V, peak pulse power 150 W (10/1000 μs), and AEC-Q101 qualification for automotive electronics protection.
For engineers reviewing the MSMP14A-M3/89A datasheet, MSMP14A-M3/89A pinout, MSMP14A-M3/89A application, or MSMP14A-M3/89A equivalent, key selection criteria include clamping voltage (23.2 V max at 6.5 A), junction temperature range (−55 °C to +150 °C), 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 unidirectional polarity to clamp transient overvoltages before they damage downstream ICs or MOSFETs. Its low-profile MicroSMP package enables high-density PCB layouts while maintaining thermal performance via 6.0 mm × 6.0 mm copper pads per terminal.
The device operates within −55 °C to +150 °C junction temperature range and delivers 150 W peak pulse power under standardized 10/1000 μs waveform. It meets J-STD-020C MSL Level 1 and passes JESD201 Class 2 whisker testing, confirming suitability for automated SMT assembly and automotive-grade reliability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ14A-E3/5AT | Higher clamping voltage (23.8 V), SMA package (larger footprint, higher RθJA = 40°C/W), same VWM/VBR range | Less suitable for ultra-thin automotive modules due to 2.3 mm height and lower thermal efficiency | Select when legacy SMA layout exists and board height is not constrained |
| 1.5SMC14A | Same VWM/VBR, but SMC package (7.1 mm × 6.2 mm), 1.5 kW PPPM, higher thermal mass | Better for high-energy industrial surges but incompatible with fine-pitch SMT lines and space-limited designs | Choose only where surge energy exceeds 150 W and board real estate permits larger footprint |
Compared with SMAJ14A-E3/5AT and 1.5SMC14A, MSMP14A-M3/89A offers the smallest form factor (MicroSMP), lowest profile (0.65 mm), and best thermal resistance to mount (RθJM = 30°C/W), making it optimal for next-generation automotive and portable electronics where size, weight, and thermal performance are critical.

FAQ
What is the exact breakdown voltage range for MSMP14A-M3/89A?
The MSMP14A-M3/89A has a guaranteed breakdown voltage (VBR) range of 15.6 V to 17.2 V at test current IT = 1.0 mA, measured per JEDEC standards. This range ensures consistent turn-on behavior across production lots and temperature extremes, enabling reliable overvoltage protection in 14 V automotive systems where MSMP14A-M3/89A is commonly deployed.
Is MSMP14A-M3/89A suitable for automotive applications?
Yes, MSMP14A-M3/89A is AEC-Q101 qualified and rated for junction temperatures from −55 °C to +150 °C, making it suitable for under-hood and cabin automotive applications. Its halogen-free M3 construction, MSL Level 1 reflow compatibility, and 15 kV ESD rating confirm its readiness for automotive-grade production, as verified in the official Vishay document 89457 for MSMP14A-M3/89A.
What is the maximum clamping voltage of MSMP14A-M3/89A at rated surge current?
The maximum clamping voltage (VC) of MSMP14A-M3/89A is 23.2 V at peak pulse current IPPM = 6.5 A (10/1000 μs waveform). This value is derived from the device's dynamic resistance (RD = 0.928 Ω) and VBRmax, ensuring protected circuits see no more than 23.2 V during worst-case surge events-critical for safeguarding 14 V nominal electronics in MSMP14A-M3/89A applications.
Does MSMP14A-M3/89A have polarity marking, and how is it identified?
Yes, MSMP14A-M3/89A features a visible cathode band on the top surface of the MicroSMP (DO-219AD) package. The band denotes the cathode terminal, which must be connected to the line being protected (e.g., signal or power rail), while the anode connects to ground. This unidirectional polarity is confirmed in the Vishay datasheet 89457 and applies strictly to MSMP14A-M3/89A-not interchangeable with bidirectional variants.
What is the thermal resistance of MSMP14A-M3/89A, and how does it affect layout?
MSMP14A-M3/89A has a typical junction-to-mount thermal resistance (RθJM) of 30 °C/W when mounted on 6.0 mm × 6.0 mm copper pads per terminal. This low value requires adherence to the recommended pad layout to maintain surge capability and avoid thermal runaway. Deviating from the specified copper area increases RθJM, reducing effective PPPM-a key design constraint for MSMP14A-M3/89A implementations.
