Product details
Overview
SMP13-M3/84A from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in DO-220AA (SMP) package, with 13 V standoff voltage (VWM), 14.4–15.9 V breakdown voltage (VBR), 400 W peak pulse power (10/1000 μs), 18.6 A peak pulse current (IPPM), and 21.5 V clamping voltage (VC). It protects MOSFETs and ICs in industrial power supplies against inductive switching transients.
For engineers reviewing the SMP13-M3/84A datasheet, SMP13-M3/84A pinout, SMP13-M3/84A application, or SMP13-M3/84A equivalent, key selection criteria include clamping voltage margin vs. protected device's absolute maximum rating, unidirectional polarity alignment with DC bias, thermal resistance (RθJA = 250 °C/W), and MSL Level 1 reflow compatibility at 260 °C peak.
Technical Context
The SMP13-M3/84A operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its specified VBR range (14.4–15.9 V at 1 mA). Its low clamping voltage (21.5 V at 18.6 A) limits stress on downstream components during transient events such as relay coil de-energization or motor commutation.
Designed for automated SMT placement, it features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, halogen-free construction per JEDEC JS709A, and RoHS compliance. The DO-220AA package delivers 1.0 mm typical height and meets UL 94 V-0 flammability rating.

Applications
| Industrial Motor Drives | Automotive Body Control Modules |
|---|---|
Use Scenario: Protection of gate drivers and microcontrollers from back-EMF spikes generated during PWM-controlled solenoid or relay switching. IC Role / Device Role / Timing Role: Unidirectional TVS placed across MOSFET drain-source or between MCU I/O and external load.

IC Role / Device Role / Timing Role: Standoff-rated TVS connected between LIN data line and ground, aligned with unidirectional bus bias. Use Value: Withstands 40 A IFSM and clamps to 21.5 V, preserving signal integrity while meeting ISO 16750-2 pulse 5a requirements. |
| Telecom Power Supply Inputs | Consumer Appliance Control Boards |
Use Scenario: Input-stage surge suppression on AC-DC adapter secondary-side 12–24 V rails feeding DSPs and PMICs. IC Role / Device Role / Timing Role: Primary-level unidirectional clamp parallel to bulk capacitor, referenced to system ground. Use Value: 400 W PPPM rating handles repetitive 10/1000 μs transients from nearby lightning-induced coupling without degradation. | Use Scenario: Protecting touch controller inputs and display driver lines from ESD and electrostatic discharge during user interaction. IC Role / Device Role / Timing Role: Localized TVS mounted directly at connector or button trace entry point. Use Value: Low 1.0 mm profile allows placement adjacent to fine-pitch connectors; 21.5 V VC avoids false triggering of 3.3 V or 5 V logic thresholds. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMP13A-M3/84A | Same electrical specs and package; identical marking code "BG" and VBR range (14.4–15.9 V) | No functional difference; SMP13-M3/84A is full part number including packaging suffix, SMP13A-M3/84A is alternate ordering format | Select SMP13-M3/84A for direct alignment with Vishay's preferred P/N and tape-and-reel configuration |
| SMBJ13A | DO-214AA (SMB) package; higher RθJA (~300 °C/W); same VWM (13 V), but higher VC (21.5 V → 23.2 V at 17.2 A) | Larger footprint (4.57 mm × 3.94 mm) and 2.3 mm height limit use in ultra-thin designs | Choose SMBJ13A only if existing PCB layout uses SMB pads and thermal derating permits higher junction rise |
Compared with SMP13A-M3/84A (identical device), SMP13-M3/84A ensures correct packaging and traceability; versus SMBJ13A, SMP13-M3/84A offers 30 % smaller footprint, 1.3 mm lower profile, and 50 °C/W lower RθJA-critical for thermally dense power supply layouts.

FAQ
What is the clamping voltage of the SMP13-M3/84A under peak surge conditions?
The SMP13-M3/84A exhibits a maximum clamping voltage (VC) of 21.5 V when subjected to its rated peak pulse current (IPPM) of 18.6 A using a 10/1000 μs waveform. This value is measured at the device terminals under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during transient events.
Is the SMP13-M3/84A suitable for bidirectional signal line protection?
No, the SMP13-M3/84A is a unidirectional transient voltage suppressor, intended for DC-biased lines such as power rails or single-ended digital signals with defined polarity. For bidirectional protection (e.g., USB, RS-485), a symmetric device like SMAJ13A or dedicated bidirectional TVS must be used instead of SMP13-M3/84A.
Does the SMP13-M3/84A meet lead-free reflow requirements?
Yes, the SMP13-M3/84A features matte tin-plated leads and is qualified for lead-free reflow soldering up to a peak temperature of 260 °C, complying with J-STD-020 MSL Level 1. Its construction supports standard Pb-free assembly processes without preconditioning or special handling.
What is the thermal resistance of the SMP13-M3/84A in standard mounting conditions?
The SMP13-M3/84A has a typical junction-to-ambient thermal resistance (RθJA) of 250 °C/W when mounted on a PCB with 5.0 mm × 5.0 mm copper pads per terminal. This value assumes minimum recommended pad layout and natural convection cooling-critical for estimating steady-state temperature rise under leakage or sustained surge conditions.
How does the SMP13-M3/84A differ from the SMP13A-M3/84A part number?
SMP13-M3/84A and SMP13A-M3/84A refer to the identical device: the "A" suffix in SMP13A denotes the 13 V VWM variant within the SMPxxA family, and "SMP13-M3/84A" is the full preferred orderable part number per Vishay's documentation. Both share identical electrical specs, DO-220AA package, marking code "BG", and qualification data.
