Product details
Overview
SMP5.0A-M3/84A from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in the SMP (DO-220AA) package, with 5.0 V stand-off voltage (VWM), 6.40–7.07 V breakdown voltage (VBR), 400 W peak pulse power (10/1000 μs), 43.5 A peak pulse current (IPPM), and 9.2 V clamping voltage (VC) at IPPM - used to protect MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and telecom equipment.
For engineers reviewing the SMP5.0A-M3/84A datasheet, SMP5.0A-M3/84A pinout, SMP5.0A-M3/84A application, or SMP5.0A-M3/84A equivalent, key selection criteria include clamping performance at 43.5 A surge, unidirectional polarity with cathode band marking, MSL Level 1 rating, halogen-free RoHS-compliant construction, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a unidirectional TVS diode, leveraging silicon avalanche breakdown to clamp transient overvoltages before they damage downstream circuitry. Its 9.2 V clamping voltage at 43.5 A ensures robust protection for 5 V logic interfaces and power rails while maintaining low incremental surge resistance.
The SMP5.0A-M3/84A is characterized under standardized 10/1000 μs waveform conditions per ANSI/IEEE C62.35, with thermal resistance of 50 °C/W (junction-to-lead) and 250 °C/W (junction-to-ambient), enabling reliable operation up to 150 °C junction temperature when mounted per recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum reverse stand-off voltage before significant leakage; defines operating threshold for 5 V systems |
| VBR min/max | 6.40 V / 7.07 V - breakdown occurs within this range at 10 mA test current; ensures consistent turn-on behavior |
| VC @ IPPM | 9.2 V - clamping voltage during 43.5 A transient; limits stress on protected 5 V ICs |
| PPPM | 400 W - peak pulse power handling with 10/1000 μs waveform; supports common surge immunity requirements |
| IFSM | 40 A - non-repetitive forward surge current rating; withstands 10 ms half-sine surges without failure |
| TJ max | +150 °C - maximum junction temperature; enables use in high-temperature industrial environments |
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 | Current entry terminal in forward bias; connected to ground or lower-potential node in unidirectional TVS configuration | Completes conduction path during transient clamping; must be routed to lowest-impedance return path |
| Cathode | Current exit terminal in forward bias; marked by color band; connected to protected line (e.g., 5 V rail or signal) | Defines polarity - reverse-biased during normal operation; avalanches to shunt surge energy to ground when V > VBR |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMP5.0A-M3/85A | Identical electrical specs; differs only in packaging - 10,000-unit 13" tape-and-reel vs. 3,000-unit 7" reel | No functional difference; suited for high-volume production runs requiring larger reels | Select SMP5.0A-M3/85A when optimizing for SMT line uptime and reduced reel change frequency |
| SMAJ5.0A | Same VWM (5.0 V) and VC (9.2 V), but SMA (DO-214AC) package - 2.4 mm height vs. SMP's 1.0 mm; RθJA = 110 °C/W vs. 250 °C/W | Higher thermal dissipation capability but larger footprint; less suitable for ultra-thin consumer modules | Choose SMAJ5.0A where board space permits and higher surge repetition rate is required |
Compared with SMP5.0A-M3/84A, the /85A variant offers identical protection performance in a higher-volume reel format, while SMAJ5.0A trades compactness for improved thermal management - making SMP5.0A-M3/84A optimal for space-constrained, high-density industrial PCBs needing MSL-1 compatibility and automated placement.

FAQ
What is the clamping voltage of the SMP5.0A-M3/84A under maximum rated surge current?
The SMP5.0A-M3/84A has a maximum clamping voltage (VC) of 9.2 V when subjected to its rated peak pulse current (IPPM) of 43.5 A using the standard 10/1000 μs waveform. This value is measured at the device terminals under defined test conditions per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for 5 V circuits. The SMP5.0A-M3/84A maintains this clamping performance across its qualified operating temperature range.
Is the SMP5.0A-M3/84A suitable for lead-free reflow soldering processes?
Yes, the SMP5.0A-M3/84A is rated for MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C, making it fully compatible with standard lead-free soldering profiles. Its matte tin-plated terminals meet J-STD-002 and JESD 22-B102 requirements, and the M3 suffix confirms compliance with JESD 201 Class 2 whisker testing. The SMP5.0A-M3/84A is designed for robust, repeatable SMT assembly without moisture sensitivity concerns.
How does the SMP5.0A-M3/84A differ from bidirectional TVS diodes?
The SMP5.0A-M3/84A is unidirectional, meaning it functions as a Zener-like clamp only in reverse bias - ideal for protecting DC power rails and single-polarity signal lines like UART or LIN. Bidirectional variants would conduct in both directions and are used for AC-coupled or differential lines such as USB or Ethernet. The SMP5.0A-M3/84A uses a cathode band for polarity identification and is not interchangeable with bidirectional types without circuit redesign.
What is the recommended PCB pad layout for optimal thermal and surge performance of the SMP5.0A-M3/84A?
Vishay specifies mounting the SMP5.0A-M3/84A on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 400 W pulse power and thermal performance. This layout minimizes trace inductance and maximizes heat spreading. Deviating from this pad size reduces IPPM derating and increases junction temperature - the SMP5.0A-M3/84A's RθJA of 250 °C/W assumes this minimum copper area, and smaller pads will compromise surge endurance.
Does the SMP5.0A-M3/84A meet automotive AEC-Q200 stress test requirements?
No, the SMP5.0A-M3/84A is specified as industrial grade and is not AEC-Q200 qualified. While it operates from −55 °C to +150 °C and meets MSL Level 1, it lacks the extended temperature cycling, vibration, and humidity testing required for automotive qualification. For AEC-Q200-compliant alternatives, engineers should consider Vishay's Automotive-grade SMP series variants explicitly marked with "AEC-Q200" in their ordering part number - the SMP5.0A-M3/84A is not one of them.
