Product details
Overview
SS10PH45HM3/87A from Vishay General Semiconductor is a high-current-density surface-mount Schottky rectifier in SMPC (TO-277A) package, rated for 10 A average forward current, 45 V reverse voltage, and 200 A surge capability, with low 0.56 V forward voltage at 10 A and 5.5 μA leakage at 25 °C - used in DC/DC converters and polarity protection circuits.
For engineers reviewing the SS10PH45HM3/87A datasheet, SS10PH45HM3/87A pinout, SS10PH45HM3/87A application, or SS10PH45HM3/87A equivalent, key selection factors include its AEC-Q101 qualification (HM3 suffix), 175 °C max junction temperature, MSL Level 1 rating, 1.1 mm profile, and guardring-enhanced overvoltage robustness in automotive and industrial power supplies.
Technical Context
This Schottky rectifier employs high-barrier technology to sustain operation up to 175 °C junction temperature while maintaining low forward voltage and minimal leakage. Its single-diode configuration and SMPC package support high-power-density board layouts with automated placement compatibility.
The device features guardring protection against transient overvoltage events and meets JESD 201 Class 2 whisker resistance requirements. Thermal resistance is specified as 60 °C/W (junction-to-ambient) and 3 °C/W (junction-to-lead), enabling efficient heat dissipation in compact power stages.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS1045CGY-TR | Same 10 A / 45 V rating; TO-277 package; VF = 0.57 V @ 10 A; no AEC-Q101 qualification | Commercial-only use; lacks automotive stress validation and guardring design | Select when cost-sensitive commercial designs require identical electrical specs without automotive compliance |

FAQ
What does the 'HM3' suffix indicate in SS10PH45HM3/87A?
The HM3 suffix in SS10PH45HM3/87A denotes AEC-Q101 qualification, halogen-free construction, and RoHS compliance. It distinguishes this automotive-grade variant from the commercial M3 version (e.g., SS10PH45-M3/87A), confirming validation for temperature cycling, high-temperature reverse bias, and mechanical shock per automotive reliability standards.
Is SS10PH45HM3/87A suitable for surface-mount reflow soldering?
Yes, SS10PH45HM3/87A is rated MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102, and the package passes JESD 201 Class 2 whisker testing - ensuring robust solder joint integrity in lead-free manufacturing.
How does the guardring feature benefit SS10PH45HM3/87A in real-world use?
The guardring in SS10PH45HM3/87A improves edge termination robustness, raising the effective breakdown voltage under transient overvoltage conditions. This allows the diode to survive repeated line surges in automotive 12 V systems without requiring external TVS devices, reducing BOM count and board area in polarity protection and freewheeling applications.
What is the thermal resistance from junction to lead (RθJL) for SS10PH45HM3/87A?
The SS10PH45HM3/87A has a typical junction-to-lead thermal resistance (RθJL) of 3 °C/W, measured under standard test conditions. This low value enables efficient heat transfer from the die directly into the PCB copper via the cathode pad, supporting higher sustained current operation than comparable devices with higher RθJL.
Can SS10PH45HM3/87A replace SS10PH45-M3/87A in an existing design?
Yes, SS10PH45HM3/87A is a direct drop-in replacement for SS10PH45-M3/87A in terms of footprint, electrical ratings, and soldering profile. The HM3 variant adds AEC-Q101 qualification and enhanced whisker resistance but maintains identical maximum ratings, forward characteristics, and thermal behavior - requiring no layout or schematic changes.
