Product details

Overview

SS3P6-M3/85A from Vishay General Semiconductor is a high-current-density surface-mount Schottky rectifier in the eSMP® SMP (DO-220AA) package, rated for 60 V reverse voltage, 3.0 A average forward current, and 45 A non-repetitive surge. It delivers low forward voltage (0.61 V at 3.0 A, 125 °C), low thermal resistance (R_θJL = 15 °C/W), and operates up to 150 °C junction temperature-ideal for compact DC/DC converters requiring efficient freewheeling.

For engineers reviewing the SS3P6-M3/85A datasheet, SS3P6-M3/85A pinout, SS3P6-M3/85A application, or SS3P6-M3/85A equivalent, key selection factors include its 60 V V_RRM, 0.61 V V_F at 3 A/125 °C, SMP package footprint, AEC-Q101-comparable construction (M3 suffix), and 13" tape-and-reel delivery (85A packaging code).

Technical Context

This Schottky rectifier uses a planar metal-silicon junction optimized for low forward voltage and fast switching with no minority-carrier storage delay. Its single-diode configuration supports unidirectional conduction in high-frequency power paths, with dV/dt capability of 10,000 V/μs ensuring robustness against rapid voltage transients.

Thermally, it leverages the SMP (DO-220AA) package's low-profile design (1.0 mm typical height) and copper pad–optimized layout to achieve R_θJL = 15 °C/W-critical for sustained 3.0 A operation on standard PCBs without forced cooling.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 48 V and lower DC bus applications.
I_F(AV)	3.0 A - Continuous average forward current at 25 °C ambient with 15 mm × 15 mm copper pad; derates linearly above 80 °C.
V_F @ 3.0 A, 125 °C	0.61 V - Low conduction loss enabling >92 % efficiency in 5–12 V output DC/DC stages at full load.
I_FSM	45 A - Peak surge rating for 8.3 ms half-sine; supports inrush and fault-current handling in converter primary-side freewheeling.
E_AS	11.25 mJ - Non-repetitive avalanche energy at 25 °C; provides limited transient overvoltage clamping capability without external TVS.
R_θJL	15 °C/W - Junction-to-lead thermal resistance measured at cathode band; enables direct thermal coupling to PCB ground plane for passive cooling.
C_J @ 4 V, 1 MHz	80 pF - Low junction capacitance minimizes switching losses and EMI in >500 kHz converter topologies.

Pinout & Package

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SS3P6HM3/85A	Identical electrical specs; HM3 suffix denotes AEC-Q101 qualified, automotive-grade version with enhanced process controls and extended test coverage.	Required for automotive production programs needing PPAP documentation and zero-defect reliability targets.	Select HM3 variant only when automotive qualification is mandated; otherwise, M3 offers identical performance at lower cost.
MBR360T3G	Same 60 V V_RRM, 3 A I_F(AV), but in SMA (DO-214AC) package; higher R_θJA (130 °C/W), taller profile (2.3 mm), and higher V_F (0.74 V @ 3 A, 25 °C).	Suitable for legacy designs using SMA footprints; not drop-in due to larger size and thermal limitations in high-density layouts.	Choose only if existing PCB layout constrains package to SMA; SS3P6-M3/85A offers superior thermal performance and space savings in new designs.

Compared with SS3P6HM3/85A and MBR360T3G, the SS3P6-M3/85A delivers optimal trade-off between commercial-grade cost, ultra-low profile (1.0 mm), and thermal performance (R_θJL = 15 °C/W), making it preferred for space- and efficiency-critical industrial and consumer DC/DC modules.

FAQ

What is the maximum junction temperature rating for SS3P6-M3/85A?

The SS3P6-M3/85A has a maximum junction temperature (T_J(max)) of +150 °C, verified per Vishay Document Number 88997. This rating allows reliable operation in under-hood automotive environments and enclosed industrial enclosures when mounted on appropriate copper pads. Derating curves in Figure 1 confirm 3.0 A I_F(AV) is maintained up to 80 °C ambient, with linear reduction thereafter. The SS3P6-M3/85A must not exceed this limit during steady-state or transient conditions.

Is SS3P6-M3/85A pin-compatible with SS3P5-M3/85A?

Yes, SS3P6-M3/85A and SS3P5-M3/85A share identical SMP (DO-220AA) package dimensions, pinout, and terminal configuration-both feature anode and cathode terminals with cathode marked by a color band. The only difference is V_RRM: 60 V for SS3P6-M3/85A versus 50 V for SS3P5-M3/85A. No PCB layout change is required when substituting within voltage-margin constraints. The SS3P6-M3/85A can replace SS3P5-M3/85A in designs needing higher reverse blocking capability.

What does the "85A" suffix indicate in SS3P6-M3/85A?

The "85A" suffix in SS3P6-M3/85A specifies the packaging format: 13-inch diameter plastic tape-and-reel with a base quantity of 10,000 units per reel. This differs from "84A", which denotes 7-inch tape-and-reel (3,000 units). Both use the same M3 halogen-free, RoHS-compliant construction. The SS3P6-M3/85A is optimized for high-volume SMT assembly lines requiring extended reel life and reduced changeover frequency.

Does SS3P6-M3/85A meet AEC-Q101 stress testing requirements?

No, SS3P6-M3/85A is a commercial-grade part with M3 suffix (halogen-free, RoHS-compliant). It is not AEC-Q101 qualified. For automotive applications requiring qualification, the SS3P6HM3/85A variant must be used-it undergoes additional stress testing including HTGB, HTRB, and temperature cycling per AEC-Q101. The SS3P6-M3/85A shares identical electrical and thermal specs but lacks the extended reliability validation required for automotive production.

What is the typical forward voltage of SS3P6-M3/85A at 3.0 A and 125 °C?

The typical forward voltage (V_F) of SS3P6-M3/85A is 0.61 V at I_F = 3.0 A and T_J = 125 °C, as specified in the Electrical Characteristics table of Vishay Document 88997. This value is confirmed across production lots and represents the median performance under those conditions. At 25 °C, V_F rises to 0.71 V (typical), confirming the negative temperature coefficient characteristic of Schottky diodes. The SS3P6-M3/85A maintains this low V_F stability across its full operating temperature range.
