SE15FGHM3/I from Vishay General Semiconductor is a surface-mount standard rectifier diode in the eSMP® Series, configured as a single silicon junction device with 400 V maximum repetitive peak reverse voltage (VRRM), 1.5 A average forward current (IF(AV)), and 0.86 V forward voltage at 1.5 A and 125 °C. It is AEC-Q101 qualified, halogen-free, RoHS-compliant, and packaged in SMF (DO-219AB) for automotive power line polarity protection.
For engineers reviewing the SE15FGHM3/I datasheet, SE15FGHM3/I pinout, SE15FGHM3/I application, or SE15FGHM3/I equivalent, key selection criteria include its 400 V VRRM, 30 A IFSM surge rating, 900 ns typical reverse recovery time, 10.5 pF junction capacitance at 4.0 V, and compatibility with wave/reflow soldering per J-STD-020 MSL level 1.
Technical Context
This device implements an oxide planar chip junction to achieve low forward voltage drop and low leakage current, supporting stable operation up to 175 °C junction temperature. Its thermal resistance is characterized by RθJA = 130 °C/W and RθJM = 20 °C/W under defined PCB mounting conditions.
The SE15FGHM3/I is rated for ESD immunity per AEC-Q101-001 Human Body Model (contact mode) with class H3B (>8 kV), and features matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102 solderability standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SE15FJHM3/I | Higher VRRM = 600 V; identical package, thermal, and surge ratings | Suitable for 400 VAC input stages or higher-voltage industrial inverters | Select when system peak reverse voltage exceeds 400 V but layout and thermal constraints match SE15FGHM3/I |
| ON Semiconductor MUR120RLG | TO-220AC package; faster trr = 75 ns; higher VF = 1.15 V at 1.5 A | Requires heatsinking; not surface-mountable; suited for higher-frequency PFC stages | Choose only if board space permits through-hole mounting and faster recovery is prioritized over low VF and compactness |
Compared with SE15FJHM3/I, the SE15FGHM3/I offers lower reverse voltage stress margin but better thermal efficiency in space-constrained automotive modules; versus MUR120RLG, it delivers superior board-level integration and lower conduction loss, though with slower recovery for high-frequency switching.

FAQ
What is the maximum junction temperature rating for the SE15FGHM3/I?
The SE15FGHM3/I has a maximum junction temperature (TJ(max)) of +175 °C, enabling reliable operation in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 105 °C. This rating is validated per AEC-Q101 stress testing and supported by its RθJA = 130 °C/W thermal resistance on a 2 oz. copper pad. The SE15FGHM3/I maintains specified electrical parameters up to this limit.
Is the SE15FGHM3/I compatible with lead-free reflow soldering processes?
Yes, the SE15FGHM3/I is fully compatible with lead-free reflow soldering, meeting J-STD-020 MSL level 1 with a maximum peak temperature of 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 solderability standards. The device is also wave-solderable and requires no pre-baking due to its moisture sensitivity classification.
Does the SE15FGHM3/I have automotive qualification?
Yes, the SE15FGHM3/I is AEC-Q101 qualified, as confirmed by its HM3 suffix and explicit documentation in Vishay's datasheet revision 13-May-2020. This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD (HBM >8 kV). The SE15FGHM3/I is approved for use in automotive powertrain, body, and chassis systems.
What does the "HM3" suffix indicate in SE15FGHM3/I?
The "HM3" suffix in SE15FGHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes the part from base "M3" variants (halogen-free/RoHS only) and confirms compliance with JESD201 Class 2 whisker resistance. The "I" indicates 13-inch tape-and-reel packaging with 10,000 units per reel.
How does the reverse recovery time of the SE15FGHM3/I affect its suitability for switching applications?
The SE15FGHM3/I has a typical reverse recovery time (trr) of 900 ns, making it appropriate for line-frequency and moderate-speed switching applications (<100 kHz), such as input rectification and freewheeling paths. It is not optimized for high-frequency PFC or resonant topologies where sub-100 ns recovery is required. For such cases, fast recovery or ultrafast diodes like the MUR120RLG would be more suitable than the SE15FGHM3/I.
