Product details

Overview

SS2P2-M3/84A from Vishay General Semiconductor is a high-current-density surface-mount Schottky barrier rectifier in the eSMP® SMP (DO-220AA) package, rated for 20 V reverse voltage, 2.0 A average forward current, and 50 A non-repetitive surge. It delivers 0.50 V forward voltage at 2 A and 25 °C, enabling low-loss operation in DC/DC converters and polarity protection circuits.

For engineers reviewing the SS2P2-M3/84A datasheet, SS2P2-M3/84A pinout, SS2P2-M3/84A application, or SS2P2-M3/84A equivalent, key selection criteria include its 1.0 mm profile, MSL Level 1 rating, 115 °C/W junction-to-ambient thermal resistance, AEC-Q101 qualification availability (via HM3 suffix), and cathode-band polarity marking.

Technical Context

This Schottky rectifier uses a planar metal-silicon junction to achieve low VF and fast switching with no minority-carrier storage delay. Its single-diode configuration supports unidirectional conduction in low-voltage, high-frequency power paths where thermal management and board space are constrained.

The SMP (DO-220AA) package features matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102, with RθJL = 15 °C/W measured at the cathode band terminal - critical for accurate thermal modeling in compact PCB layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	20 V - maximum reverse blocking capability for 12 V and 5 V rail protection
I_F(AV)	2.0 A - continuous forward current handling at 75 °C ambient on standard PCB pad
V_F @ 2 A, 25 °C	0.50 V - enables <1.0 W conduction loss at full load in 12 V systems
I_FSM	50 A - withstands short-duration inrush and fault currents in DC/DC startup
E_AS	11.25 mJ - avalanche energy rating supports freewheeling in inductive switching
R_θJA	115 °C/W - defines temperature rise under natural convection on 6 mm × 6 mm copper pad
T_J max.	150 °C - allows operation in automotive under-hood and industrial environments

Pinout & Package

Package: SMP (DO-220AA), 2-terminal surface-mount case with 1.0 mm typical height, cathode identified by color band. Molding compound meets UL 94 V-0; terminals are matte tin plated per J-STD-002.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to input/source side of rectification path; requires low-impedance trace routing
Cathode (marked)	Forward current exit point / reverse-blocking terminal	Color band identifies polarity; terminal location defines thermal path to PCB pad per R_θJL = 15 °C/W

Key Features

Feature	Design Value
Very low profile (1.0 mm)	Enables use in ultra-thin power modules and stacked-board assemblies
Low thermal resistance (R_θJL = 15 °C/W)	Supports higher sustained current without derating when soldered to large copper area
MSL Level 1 (260 °C peak)	Compatible with standard lead-free reflow profiles without preconditioning
AEC-Q101 qualified option (HM3 suffix)	Validated for automotive powertrain and body electronics applications
Halogen-free, RoHS-compliant (M3)	Meets environmental compliance requirements for commercial and industrial end equipment

Applications

DC/DC Converter Output Rectification	Polarity Protection

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SS2P2HM3/84A	AEC-Q101 qualified; identical electrical specs and package; HM3 denotes automotive grade	Required for automotive production; same footprint but stricter process controls and traceability	Select SS2P2HM3/84A when automotive qualification is mandatory; otherwise SS2P2-M3/84A suffices for commercial use
MBR220LSFT1G	2 A / 20 V Schottky in SOD-123FL; V_F = 0.52 V @ 2 A; R_θJA = 170 °C/W; no MSL Level 1 rating	Limited to lower-power, less thermally demanding applications due to higher thermal resistance and narrower reflow compatibility	Choose MBR220LSFT1G only if SOD-123FL footprint is fixed and thermal budget allows >50 °C/W higher R_θJA

Compared with SS2P2HM3/84A, the SS2P2-M3/84A offers identical performance in commercial environments but lacks automotive qualification documentation; versus MBR220LSFT1G, it delivers superior thermal performance and broader reflow compatibility at the cost of slightly larger footprint.

FAQ

What is the maximum junction temperature rating for SS2P2-M3/84A?

The SS2P2-M3/84A has a maximum junction temperature (T_J) of +150 °C, allowing reliable operation in high-ambient environments such as enclosed industrial enclosures or automotive under-dash locations. This rating is maintained across its full operating range from –55 °C to +150 °C, and thermal design must account for R_θJA = 115 °C/W on standard PCB layout. The SS2P2-M3/84A datasheet specifies derating curves to ensure safe operation at elevated temperatures.

Is SS2P2-M3/84A suitable for lead-free reflow soldering?

Yes, SS2P2-M3/84A meets MSL Level 1 per J-STD-020 with a maximum peak reflow temperature of 260 °C, making it fully compatible with standard lead-free soldering processes without preconditioning. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102, and the M3 suffix confirms halogen-free, RoHS-compliant construction. The SS2P2-M3/84A package is validated for repeated exposure to industry-standard thermal profiles.

How does the forward voltage of SS2P2-M3/84A vary with temperature?

The forward voltage of SS2P2-M3/84A decreases with rising junction temperature: it is 0.50 V at 2 A and 25 °C, and drops to 0.43 V at 2 A and 125 °C. This negative temperature coefficient improves thermal stability in parallel configurations and reduces conduction loss at elevated operating temperatures. The SS2P2-M3/84A datasheet provides full V_F vs. T_J curves to support accurate loss modeling across the –55 °C to +150 °C range.

What is the reverse leakage current specification for SS2P2-M3/84A at high temperature?

At rated reverse voltage and 125 °C, the SS2P2-M3/84A exhibits a maximum reverse leakage current (I_R) of 15 mA - significantly higher than its 150 μA maximum at 25 °C. This increase is inherent to Schottky physics and must be accounted for in low-power standby circuits. The SS2P2-M3/84A datasheet specifies both values explicitly, and designers should verify system-level leakage budgets using the 125 °C value for worst-case analysis.

Does SS2P2-M3/84A have an automotive-grade variant?

Yes, the SS2P2HM3/84A is the AEC-Q101 qualified automotive-grade variant of SS2P2-M3/84A, sharing identical electrical specifications, package, and pinout. It undergoes additional stress testing and process controls required for automotive applications. While SS2P2-M3/84A is commercial-grade, the SS2P2HM3/84A is designated for use in automotive body electronics, infotainment, and ADAS subsystems where qualification is mandatory.
