Product details
Overview
SS3P5HM3/84A from Vishay General Semiconductor is an AEC-Q101-qualified, high-current-density surface-mount Schottky rectifier in the SMP (DO-220AA) package, rated for 50 V repetitive peak reverse voltage and 3.0 A average forward current, with 0.61 V forward voltage at 3.0 A and 125 °C junction temperature. It serves as a low-loss freewheeling or polarity protection diode in automotive DC/DC converters.
For engineers reviewing the SS3P5HM3/84A datasheet, SS3P5HM3/84A pinout, SS3P5HM3/84A application, or SS3P5HM3/84A equivalent, key selection factors include its automotive-grade qualification (HM3 suffix), 150 °C max junction temperature, 11.25 mJ non-repetitive avalanche energy, 10,000 V/μs voltage rate of change, and SMP package compatibility with automated placement and J-STD-020 MSL level 1 reflow.
Technical Context
The SS3P5HM3/84A implements a single-anode/cathode Schottky barrier structure optimized for low VF and fast switching in low-voltage power conversion. Its junction capacitance is 80 pF at 4.0 V and 1 MHz, supporting high-frequency operation up to several hundred kHz in DC/DC topologies.
Thermal design is enabled by low thermal resistance: RθJL = 15 °C/W and RθJC = 20 °C/W when mounted on PCB with 15 mm × 15 mm copper pads. The device operates across -55 °C to +150 °C and meets JESD 201 class 2 whisker test requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS3P5-M3/84A | Commercial-grade version; same electrical specs but not AEC-Q101 qualified | Not suitable for automotive under-hood use; acceptable for industrial or consumer power supplies | Select SS3P5-M3/84A where automotive qualification is unnecessary and cost sensitivity is higher |
| SB350-E3/52T | Same IF(AV) and VRRM, but DO-214AA package; VF = 0.72 V @ 3 A, 25 °C; RθJA = 65 °C/W | Higher thermal resistance limits power density; larger footprint increases board area | Choose SB350-E3/52T only if legacy DO-214AA layout exists and thermal budget allows 15 °C higher junction rise |
Compared with SS3P5-M3/84A, the SS3P5HM3/84A adds automotive qualification and whisker-tested terminations at identical electrical performance; versus SB350-E3/52T, it delivers 30 % lower profile, 40 % better thermal resistance to lead, and tighter VF distribution-critical for high-density, thermally constrained automotive designs.

FAQ
What is the maximum junction temperature rating for SS3P5HM3/84A?
The SS3P5HM3/84A has a maximum junction temperature (TJ max.) of +150 °C, verified per AEC-Q101 stress testing. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating begins above 80 °C ambient, as shown in Figure 1 of the datasheet. Thermal design must account for RθJL = 15 °C/W to ensure the SS3P5HM3/84A stays within this limit under full load.
Is SS3P5HM3/84A pin-compatible with SS3P5-M3/84A?
Yes, SS3P5HM3/84A and SS3P5-M3/84A share identical SMP (DO-220AA) package dimensions, pinout, and solder pad layout. The only differences are qualification grade (automotive HM3 vs. commercial M3) and whisker test compliance-both meet JESD 201 class 2. No PCB redesign is required when upgrading from SS3P5-M3/84A to SS3P5HM3/84A in existing automotive designs.
What does the 'HM3' suffix indicate in SS3P5HM3/84A?
The 'HM3' suffix in SS3P5HM3/84A denotes halogen-free, RoHS-compliant construction with automotive-grade qualification (AEC-Q101) and JESD 201 class 2 whisker resistance. It distinguishes the part from the commercial 'M3' variant and confirms compliance with automotive reliability standards, including extended temperature cycling and humidity testing beyond JEDEC requirements.
Does SS3P5HM3/84A support reflow soldering per J-STD-020?
Yes, SS3P5HM3/84A is rated MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Its matte tin-plated terminals are solderable per J-STD-002 and JESD 22-B102. The device may be placed directly from reel (84A packaging) and processed using standard lead-free reflow profiles without preconditioning or dry-pack requirements.
What is the typical forward voltage drop of SS3P5HM3/84A at 3.0 A and 125 °C?
The typical forward voltage drop of SS3P5HM3/84A is 0.61 V at 3.0 A and 125 °C junction temperature, as specified in the Electrical Characteristics table. This value reflects real-world operating conditions in automotive power supplies and enables accurate loss modeling. At 25 °C, VF is 0.71 V (typical), confirming the device's strong temperature stability-critical for consistent performance across wide ambient ranges.
