Product details
Overview
SMP16-M3/84A from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features a 16 V standoff voltage (VWM), 17.8–19.7 V breakdown voltage (VBR), 400 W peak pulse power (10/1000 μs), 15.4 A peak pulse current (IPPM), and clamps to ≤26.0 V at rated surge. It is used to protect MOSFET gates, microcontroller I/O, and sensor interfaces in industrial motor drives.
For engineers reviewing the SMP16-M3/84A datasheet, SMP16-M3/84A pinout, SMP16-M3/84A application, or SMP16-M3/84A equivalent, key selection criteria include unidirectional polarity, DO-220AA (SMP) package compatibility with automated placement, 1.0 mm profile height, MSL Level 1 rating, and verified clamping performance under 10/1000 μs surge conditions.
Technical Context
The SMP16-M3/84A operates as a silicon avalanche diode optimized for fast transient suppression in DC power and low-voltage signal paths. Its unidirectional configuration enables integration into positive-rail protection schemes without reverse-bias leakage concerns above 16 V.
It delivers 400 W peak pulse power per JEDEC-standard 10/1000 μs waveform, with clamping voltage fixed at ≤26.0 V at 15.4 A IPPM and thermal resistance RθJA of 250 °C/W. The device is rated for TJ = –55 °C to +150 °C and meets JESD201 Class 1A whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 15 V nominal rails. |
| VBR min/max | 17.8 V / 19.7 V - Breakdown occurs within this range at 1 mA test current; ensures predictable turn-on threshold across production lot. |
| VC @ IPPM | ≤26.0 V - Clamping voltage at 15.4 A surge; limits downstream voltage stress during worst-case transients. |
| PPPM | 400 W - Peak pulse power handling with 10/1000 μs waveform; supports robust protection against IEC 61000-4-5 Level 4 surges. |
| IFSM | 40 A - Non-repetitive forward surge current rating (10 ms half-sine); validates resilience to accidental polarity reversal events. |
| TJ max | +150 °C - Maximum junction temperature; enables use in enclosed industrial enclosures with limited airflow. |
Pinout & Package
Package: DO-220AA (SMP), ultra-low-profile surface-mount case with matte tin-plated leads, 1.0 mm typical height, halogen-free and RoHS-compliant (M3 suffix), MSL Level 1, LF peak reflow 260 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to ground or low-side return path in unidirectional TVS configuration; carries surge current during clamping. |
| Cathode | Reverse-biased clamping terminal | Marked with color band; connected to protected line (e.g., 15 V rail); initiates avalanche breakdown when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 1.0 mm typical height - Enables use in space-constrained modules such as portable industrial sensors and compact motor controllers. |
| Automated placement compatibility | DO-220AA (SMP) footprint with defined lead geometry - Supports high-yield pick-and-place assembly at >30,000 UPH without tombstoning. |
| Low incremental surge resistance | Ensures minimal voltage overshoot during fast-rising transients (<1 ns rise time), critical for protecting sub-20 V logic interfaces. |
| Fast response time | Sub-nanosecond avalanche turn-on - Limits energy delivery to protected ICs before internal ESD structures activate. |
Applications
| Industrial Motor Drive Protection | Automotive Body Control Module (BCM) |
|---|---|
|
Use Scenario: Suppresses inductive kickback from relay coils and solenoid drivers in PLC output modules. IC Role / Device Role / Timing Role: Unidirectional TVS placed between coil supply rail and ground to clamp flyback voltage spikes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMP16A-M3/84A | Identical electrical specs and DO-220AA package; same marking code BP; differs only in part number formatting (no hyphen in base P/N). | No functional difference; both qualify for same industrial and automotive surge standards. | Select SMP16A-M3/84A if sourcing from distributors listing the base P/N without hyphen; identical performance and fit. |
| SMBJ16A | DO-214AA (SMB) package, 1.7 mm height, 600 W PPPM, higher clamping voltage (≤26.0 V vs. ≤26.5 V), larger footprint. | Preferred where higher surge margin is needed and board space permits larger package; not drop-in compatible due to size and pad layout. | Choose SMBJ16A only when 400 W is insufficient and PCB redesign accommodates SMB pads; SMP16-M3/84A remains optimal for height-constrained designs. |
Compared with SMP16A-M3/84A (identical function, alternate naming) and SMBJ16A (higher power but larger DO-214AA package), the SMP16-M3/84A provides the lowest profile (1.0 mm) and smallest footprint for 400 W unidirectional TVS protection, making it ideal for modern miniaturized industrial and automotive electronics where vertical clearance and board area are constrained.

FAQ
What is the standoff voltage rating of the SMP16-M3/84A?
The SMP16-M3/84A has a reverse standoff voltage (VWM) of 16 V, meaning it remains non-conductive up to this DC or RMS voltage level. This rating ensures compatibility with 15 V nominal systems while providing sufficient margin before avalanche breakdown initiates at 17.8–19.7 V. The SMP16-M3/84A maintains low leakage (<1.0 μA at VWM) to avoid loading sensitive circuits during normal operation.
Does the SMP16-M3/84A meet automotive qualification standards?
The SMP16-M3/84A is not AEC-Q200 qualified, but its specifications-150 °C max junction temperature, MSL Level 1, JESD201 Class 1A whisker resistance, and 400 W surge capability-support use in non-safety-critical automotive applications like body control modules and infotainment power rails. For SMP16-M3/84A deployment in automotive contexts, system-level validation per ISO 7637-2 and IEC 61000-4-5 remains the responsibility of the end designer.
What does the "M3/84A" suffix indicate in SMP16-M3/84A?
In SMP16-M3/84A, "M3" denotes halogen-free, RoHS-compliant construction with matte tin-plated leads passing JESD201 Class 1A whisker testing, while "84A" specifies the packaging format: 7-inch diameter plastic tape and reel containing 3000 units. This suffix confirms full compliance with environmental and assembly requirements for high-volume SMT manufacturing.
How does the clamping voltage of SMP16-M3/84A compare to its breakdown voltage?
The SMP16-M3/84A breaks down between 17.8 V and 19.7 V at 1 mA (VBR), but clamps to ≤26.0 V at its rated 15.4 A peak pulse current (IPPM). This ~6–8 V differential reflects the device's low dynamic impedance during surge events, ensuring protected circuitry sees significantly less overvoltage than the initial transient amplitude-critical for safeguarding 20 V-tolerant ICs.
Can SMP16-M3/84A be used in bidirectional configurations?
No-the SMP16-M3/84A is strictly unidirectional, with cathode marked by a color band and specified only for reverse-biased clamping applications. For bidirectional transient suppression, Vishay offers separate dual-diode configurations (e.g., SMBJ16CA); using SMP16-M3/84A in reverse orientation risks permanent failure due to forward conduction beyond its 40 A IFSM rating.
