Product details
Overview
SMP16A-M3/84A from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in the SMP (DO-220AA) package, featuring 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 26.0 V clamping voltage (VC) at IPPM - used for protecting MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and telecom equipment.
For engineers reviewing the SMP16A-M3/84A datasheet, SMP16A-M3/84A pinout, SMP16A-M3/84A application, or SMP16A-M3/84A equivalent, key selection criteria include clamping performance under 10/1000 μs surge, unidirectional polarity with cathode band marking, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
The SMP16A-M3/84A operates as a unidirectional TVS diode optimized for fast response to voltage transients, with low incremental surge resistance and excellent clamping linearity across its rated surge current range. Its junction-to-lead thermal resistance (RθJL = 50 °C/W) supports reliable power dissipation during repetitive or single-pulse events when mounted per recommended pad layout.
Designed for PCB-level protection of sensitive nodes, it delivers stable reverse leakage (<1.0 μA at VWM) and low forward voltage (VF = 2.5 V at 25 A), enabling integration into low-voltage signal paths without compromising system bias conditions or forward conduction integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before clamping begins; defines safe working margin for protected circuitry. |
| VBR min/max | 17.8 V / 19.7 V - breakdown voltage range at 1.0 mA test current; ensures predictable turn-on threshold under ESD/surge stress. |
| VC @ IPPM | 26.0 V - clamping voltage at 15.4 A peak pulse current; limits transient overvoltage seen by downstream components. |
| PPPM | 400 W - peak pulse power handling capability with 10/1000 μs waveform; validates robustness against IEC 61000-4-5 level 4 surges. |
| IFSM | 40 A - non-repetitive forward surge current rating (10 ms half-sine); supports high-energy fault clearing in power rails. |
| TJ max | +150 °C - maximum junction temperature; enables operation in industrial ambient environments with adequate PCB thermal design. |
Pinout & Package
Package: SMP (DO-220AA), ultra-low-profile surface-mount case with matte tin-plated leads, 1.0 mm typical height, UL 94 V-0 molding compound, and cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected node; conducts during positive transients when used in unidirectional configuration. |
| Cathode | Clamping reference terminal | Marked with color band; connected to higher-potential side (e.g., VCC rail or signal line); defines polarity and clamping direction. |
Key Features
| Feature | Design Value |
|---|---|
| Peak pulse power | 400 W with 10/1000 μs waveform - enables compliance with IEC 61000-4-5 surge immunity requirements up to level 4. |
| Clamping ratio (VC/VBR) | ~1.38 - low ratio confirms efficient voltage limiting with minimal overshoot during transient events. |
| Response time | <1.0 ns - ensures suppression activation before sensitive logic or analog circuitry sustains damage. |
| MSL rating | Level 1 per J-STD-020 - allows unlimited floor life and reflow at 260 °C peak without baking preconditioning. |
| Halogen-free & RoHS | M3 suffix - meets industrial-grade environmental compliance and whisker resistance (JESD 201 Class 2). |

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-M3/85A | Same electrical specs; differs only in packaging - 13" tape-and-reel (10,000 pcs) vs. 7" reel (3,000 pcs) of SMP16A-M3/84A. | Identical use cases; selected for high-volume production runs requiring larger reels and reduced changeover frequency. | Choose SMP16A-M3/85A when optimizing for SMT line efficiency in mass manufacturing. |
| SMAJ16A | Same VWM (16 V), but higher VC (33.0 V), lower PPPM (400 W same), and SMA (DO-214AC) package - 2.3 mm height vs. 1.0 mm. | Less suitable for ultra-thin designs; requires larger PCB footprint and has higher thermal resistance (RθJA = 40°C/W vs. 250°C/W). | Use SMAJ16A only if DO-220AA mechanical constraints prevent SMP16A-M3/84A placement. |
Compared with SMP16A-M3/84A, the /85A variant offers identical protection performance with logistics advantages for volume builds, while SMAJ16A trades compactness and thermal efficiency for legacy package compatibility - making SMP16A-M3/84A optimal for space-constrained, thermally demanding, or high-reliability industrial layouts.

FAQ
What is the clamping voltage of SMP16A-M3/84A at its rated peak pulse current?
The SMP16A-M3/84A exhibits a maximum clamping voltage (VC) of 26.0 V when subjected to its rated peak pulse current (IPPM) of 15.4 A using a 10/1000 μs waveform. This value is measured under standardized test conditions per ANSI/IEEE C62.35 and reflects the actual voltage imposed on protected circuitry during worst-case surge events. The SMP16A-M3/84A maintains this clamping performance consistently across its specified operating temperature range.
Is SMP16A-M3/84A suitable for bidirectional transient protection?
No, SMP16A-M3/84A is a unidirectional transient voltage suppressor, as confirmed by its polarity marking (cathode band) and electrical specifications including VBR and VWM defined only for reverse-biased operation. For bidirectional protection, Vishay offers separate part numbers such as SMBJ16CA; the SMP16A-M3/84A must be used with correct orientation relative to the protected node's voltage reference to ensure proper clamping function.
What is the maximum operating temperature for SMP16A-M3/84A?
The SMP16A-M3/84A has a maximum junction temperature (TJ max) of +150 °C and an operating junction and storage temperature range of -55 °C to +150 °C. This rating applies under specified thermal conditions - including mounting on 5.0 mm × 5.0 mm copper pads per terminal - and supports deployment in extended-temperature industrial environments where ambient temperatures may reach +85 °C or higher with appropriate PCB thermal design.
Does SMP16A-M3/84A meet RoHS and halogen-free requirements?
Yes, SMP16A-M3/84A carries the M3 suffix, indicating full compliance with RoHS Directive 2011/65/EU and halogen-free material composition per IEC 61249-2-21. It also satisfies JESD 201 Class 2 whisker resistance testing and is rated for industrial-grade reliability, making it suitable for environmentally regulated applications without requiring exemptions or special declarations.
What is the surge current rating for SMP16A-M3/84A using the 10/1000 μs waveform?
The SMP16A-M3/84A is rated for a peak pulse current (IPPM) of 15.4 A when tested with the standard 10/1000 μs double-exponential surge waveform. This value is derived directly from its 400 W peak pulse power rating and 26.0 V clamping voltage (IPPM = PPPM / VC). The rating assumes proper PCB mounting per Vishay's recommended 5.0 mm × 5.0 mm copper pad layout and is valid for non-repetitive pulses at TA = 25 °C.
