Product details
Overview
SS3P3HM3/85A from Vishay General Semiconductor is an AEC-Q101-qualified, automotive-grade Schottky barrier rectifier in SMP (DO-220AA) package, rated for 3.0 A average forward current, 30 V repetitive peak reverse voltage, and 0.43 V forward voltage at 3 A and 125 °C. It delivers low thermal resistance (RθJL = 15 °C/W), high surge capability (50 A IFSM), and polarity protection in space-constrained DC/DC converters.
For engineers reviewing the SS3P3HM3/85A datasheet, SS3P3HM3/85A pinout, SS3P3HM3/85A application, or SS3P3HM3/85A equivalent, key selection criteria include its automotive qualification, 1.0 mm profile, MSL Level 1 rating, 150 °C junction temperature limit, and SMP package compatibility with automated SMT placement.
Technical Context
This device is a single-die, planar Schottky rectifier optimized for high-frequency switching applications where low forward voltage and fast recovery are critical. Its construction uses a metal–semiconductor junction to eliminate minority-carrier storage delay, enabling zero-recovery charge and minimal switching loss.
The SS3P3HM3/85A operates across -55 °C to +150 °C junction temperature range, supports 10,000 V/μs dV/dt, and exhibits 130 pF typical junction capacitance at 4.0 V and 1 MHz - parameters directly enabling efficient operation in 100 kHz–1 MHz DC/DC topologies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS3P3-M3/85A | Commercial-grade variant; identical electrical specs but not AEC-Q101 qualified | Suitable for industrial or consumer DC/DC where automotive qualification is unnecessary | Select SS3P3HM3/85A only when AEC-Q101 compliance is mandated for automotive deployment |
| SB330-TB-E3/52T | Same IF(AV) and VRRM, but SMC (DO-214AB) package; RθJA = 40 °C/W vs. 95 °C/W for SS3P3HM3/85A | Better thermal performance in open-air convection, but larger footprint and height (2.3 mm) | Choose SB330-TB-E3/52T if board-level airflow exists and space permits larger package |
Compared with SS3P3-M3/85A, the SS3P3HM3/85A adds automotive qualification and whisker resistance without electrical trade-offs; versus SB330-TB-E3/52T, it trades thermal resistance for 58 % lower profile and 47 % smaller footprint - critical for dense automotive modules.

FAQ
What is the maximum junction temperature rating for the SS3P3HM3/85A?
The SS3P3HM3/85A has a maximum operating junction temperature of +150 °C, validated per AEC-Q101 stress testing. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial settings. The device's RθJL of 15 °C/W allows effective heat transfer to the PCB, helping maintain safe TJ under sustained 3.0 A load. Always verify actual TJ using measured case temperature and thermal model in final layout.
Is the SS3P3HM3/85A pin-compatible with SS3P3-M3/85A?
Yes, the SS3P3HM3/85A is mechanically and electrically pin-compatible with SS3P3-M3/85A - both use identical SMP (DO-220AA) package, anode/cathode terminal layout, and marking orientation. The only differences are qualification level (AEC-Q101 vs. commercial) and whisker test compliance (both meet JESD 201 Class 2). No PCB redesign is needed when upgrading from SS3P3-M3/85A to SS3P3HM3/85A.
What does the "HM3" suffix indicate in SS3P3HM3/85A?
The "HM3" suffix in SS3P3HM3/85A denotes the automotive-grade version: "H" signifies AEC-Q101 qualification and enhanced reliability testing, while "M3" indicates halogen-free, RoHS-compliant construction with matte tin plating and JESD 201 Class 2 whisker resistance. This distinguishes it from the commercial "M3" variant (SS3P3-M3/85A), which lacks automotive qualification.
Can the SS3P3HM3/85A be used in synchronous rectification topologies?
No - the SS3P3HM3/85A is a passive Schottky rectifier, not a synchronous rectifier controller or MOSFET driver. It functions as a unidirectional current valve and cannot replace active gate-driven MOSFETs in synchronous buck or flyback stages. However, it serves effectively as the freewheeling or output rectifier in asynchronous topologies where its low VF and zero QRR provide efficiency advantages over PN diodes.
What tape-and-reel packaging does SS3P3HM3/85A ship in?
The SS3P3HM3/85A ships in 13-inch diameter plastic tape and reel, with a base quantity of 10,000 units per reel (package code 85A). This format supports high-speed automated pick-and-place assembly. The tape meets EIA-481 standards, and the device is packed per MSL Level 1 requirements - no baking required prior to reflow.
