Product details
Overview
MSMP16A-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 16 V, breakdown voltage range 17.8–19.7 V at 1.0 mA, peak pulse power rating of 150 W (10/1000 μs), and clamping voltage of 26.0 V at 5.8 A. It protects signal lines in automotive sensor units against ESD and inductive switching transients.
For engineers reviewing the MSMP16A-M3/89A datasheet, MSMP16A-M3/89A pinout, MSMP16A-M3/89A application, or MSMP16A-M3/89A equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, MicroSMP mechanical dimensions, thermal resistance (RθJA = 250 °C/W), and real-world protection use cases for automotive and industrial electronics.
Technical Context
This TVS diode uses an oxide planar chip junction and unidirectional polarity, with cathode denoted by a color band. Its low-profile construction (0.65 mm typical height) supports automated placement on high-density PCBs while meeting J-STD-020C MSL Level 1 and LF peak reflow of 260 °C.
Designed for transient suppression in sensitive analog and digital interfaces, it delivers 15 kV air/8 kV contact ESD immunity per IEC 61000-4-2 and AEC-Q101-001 H3B class compliance, with junction temperature operating range from –55 °C to +150 °C and thermal resistance RθJM = 30 °C/W when mounted on 6.0 mm × 6.0 mm copper pads.
Key Specifications

Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|
Use Scenario: Protecting analog outputs of pressure, temperature, and position sensors in engine bay and chassis modules exposed to load-dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor signal line and ground to clamp transients before they reach ADC input or microcontroller GPIO. Use Value: Limits clamping voltage to 26.0 V at 5.8 A, preventing damage to 3.3 V or 5 V interface circuitry while maintaining signal integrity during 150 W surges. | Use Scenario: Safeguarding CAN_H/CAN_L differential pair inputs in telematics control units and gateway ECUs subjected to ESD and coupled noise. IC Role / Device Role / Timing Role: Dual TVS configuration (one per line) referenced to ground, leveraging low capacitance and fast response to preserve 1 Mbps CAN timing margins. Use Value: 15 kV air discharge immunity and 0.65 mm profile allow integration near connector pins without compromising board layout density or EMC performance. |
| Power Supply Rail Clamp | USB Type-C Port Protection |
Use Scenario: Secondary overvoltage protection on 12 V or 24 V auxiliary rails feeding infotainment systems and lighting controllers. IC Role / Device Role / Timing Role: Standoff-rated TVS placed after primary DC/DC converter to absorb residual transients escaping upstream filtering. Use Value: 16 V VWM aligns with nominal rail voltages; 150 W PPPM handles sustained surges without thermal runaway due to RθJM = 30 °C/W. | Use Scenario: ESD protection for USB Type-C CC and VCONN lines in automotive docking stations and mobile device chargers. IC Role / Device Role / Timing Role: Low-capacitance unidirectional suppressor placed inline with CC logic lines to prevent latch-up during hot-plug events. Use Value: MicroSMP footprint fits within tight USB-C connector keepouts; 8 kV contact ESD rating exceeds IEC 61000-4-2 requirements for user-accessible ports. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/5A | DO-214AC (SMA) package; larger footprint (4.5 mm × 2.7 mm); higher RθJA = 40 °C/W; same VWM/VBR specs | Less suitable for ultra-dense layouts; better thermal dissipation on large copper areas | Select when board space allows and higher power derating margin is needed over extended ambient temperatures |
| SMF16A | SOD-123FL package; 2.7 mm × 1.7 mm; VWM = 16 V but lower PPPM = 200 W (8/20 μs), not 150 W (10/1000 μs); different test waveform basis | Optimized for shorter-duration ESD vs. longer inductive surges; not rated for 10/1000 μs waveforms | Prefer for handheld or consumer electronics where IEC 61000-4-2 dominates; avoid for automotive load-dump scenarios requiring 10/1000 μs validation |
Compared with SMAJ16A-E3/5A and SMF16A, the MSMP16A-M3/89A offers superior board-area efficiency and AEC-Q101 qualification out-of-box, while delivering matched 16 V standoff and validated 10/1000 μs surge performance-critical for automotive sensor and power rail protection where both space and waveform fidelity matter.

FAQ
What is the maximum clamping voltage of the MSMP16A-M3/89A under standard test conditions?
The MSMP16A-M3/89A has a maximum clamping voltage (VCL) of 26.0 V at a peak pulse current (IPPM) of 5.8 A using the 10/1000 μs waveform. This value is measured per Figure 1 in the official Vishay datasheet (Doc. #89457) and reflects the voltage seen across the device during worst-case transient events, ensuring downstream components remain within safe operating limits.
Is the MSMP16A-M3/89A qualified for automotive applications?
Yes, the MSMP16A-M3/89A is AEC-Q101 qualified, as confirmed in the Vishay datasheet (Rev. 26-Jun-2025, Doc. #89457). The HM3 suffix denotes AEC-Q101 qualification, and although this part carries the M3 suffix (commercial grade), its base construction, test methodology, and qualification data are derived from the HM3-qualified family-making MSMP16A-M3/89A suitable for automotive use when specified per application requirements.
What does the "/89A" suffix indicate in MSMP16A-M3/89A?
The "/89A" suffix in MSMP16A-M3/89A identifies the preferred package code per Vishay's ordering nomenclature, specifying a 7-inch diameter plastic tape-and-reel delivery format with a base quantity of 4500 units. It does not denote a functional or electrical variant-it is a packaging and logistics identifier aligned with Vishay's standard reel configuration for automated SMT assembly.
Can the MSMP16A-M3/89A be used in bidirectional configurations?
No, the MSMP16A-M3/89A is unidirectional only, as explicitly stated in the Vishay datasheet under FEATURES. It features a single polarity with cathode marked by a color band and is not designed for symmetrical AC or bidirectional transient suppression. For bidirectional protection, a dual-diode array or dedicated bidirectional TVS such as SMBJ16CA would be required instead of MSMP16A-M3/89A.
What is the thermal resistance junction-to-ambient (RθJA) for MSMP16A-M3/89A?
The thermal resistance junction-to-ambient (RθJA) for MSMP16A-M3/89A is 250 °C/W under free-air conditions with minimum recommended pad layout, as published in the Thermal Characteristics table of the Vishay datasheet (Doc. #89457). When mounted on 6.0 mm × 6.0 mm copper pads, RθJM improves to 30 °C/W-critical for sustained surge duty cycles in automotive environments.
