Product details

Overview

SE15FDHM3/H from Vishay General Semiconductor is a surface-mount standard rectifier diode in the eSMP® Series, configured as a single silicon junction device with 200 V maximum repetitive peak reverse voltage (V_RRM), 1.5 A average forward current (I_F(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 SE15FDHM3/H datasheet, SE15FDHM3/H pinout, SE15FDHM3/H application, or SE15FDHM3/H equivalent, key selection criteria include its 175 °C maximum junction temperature, 30 A non-repetitive surge rating (I_FSM), low leakage (5 μA at 25 °C), 900 ns typical reverse recovery time, and compatibility with wave/reflow soldering per J-STD-020 MSL Level 1.

Technical Context

This diode employs an oxide planar chip junction to achieve low forward voltage drop and low leakage current while maintaining robust thermal performance. Its SMF (DO-219AB) package delivers 20 °C/W junction-to-mount thermal resistance (R_θJM) and supports high-density automated placement on PCBs with 2 oz. copper pads.

The device is rated for operation from –55 °C to +175 °C and exhibits ESD immunity per AEC-Q101-001 Human Body Model (H3B class, >8 kV). Reverse recovery behavior is characterized at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A, yielding a typical t_rr of 900 ns - critical for moderate-speed switching in DC power conditioning.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - blocks up to 200 V reverse voltage without breakdown in repetitive applications
I_F(AV)	1.5 A - continuous DC forward current capability at T_A = 25 °C with recommended PCB layout
V_F @ 1.5 A, 125 °C	0.86 V - low conduction loss enabling efficient power conversion at elevated temperatures
I_R @ V_R, 25 °C	5 μA - minimal reverse leakage preserves system efficiency in standby or high-impedance circuits
t_rr	900 ns - enables use in 100–500 kHz rectification where fast recovery reduces switching losses
T_J max.	175 °C - supports operation in under-hood automotive environments and thermally constrained industrial enclosures
R_θJM	20 °C/W - low junction-to-mount thermal resistance allows effective heat transfer to heatsink or copper plane

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay SE15FD-M3/H	No AEC-Q101 qualification; same V_RRM, I_F(AV), V_F, and package	Not approved for automotive use; suitable for commercial/industrial only	Select when AEC-Q101 is not required and cost optimization is prioritized
ON Semiconductor NSVR1520HT1G	Same 200 V V_RRM, 1.5 A I_F(AV), but higher V_F (1.1 V typ. @ 1.5 A), no AEC-Q101 data published	Limited to commercial-grade applications; lower thermal robustness (T_J max. = 150 °C)	Choose only if footprint compatibility and supply chain diversification outweigh V_F and temperature penalties

Compared with SE15FD-M3/H and NSVR1520HT1G, the SE15FDHM3/H uniquely combines AEC-Q101 qualification, 175 °C junction rating, and 0.86 V forward voltage - making it the sole option among these three for thermally demanding automotive rectification where reliability validation is mandatory.

FAQ

What is the maximum junction temperature rating for SE15FDHM3/H?

The SE15FDHM3/H has a maximum junction temperature (T_J max.) of +175 °C, verified per AEC-Q101 qualification testing. This rating allows reliable operation in under-hood automotive environments and thermally constrained industrial enclosures where ambient temperatures exceed 125 °C. The device maintains specified electrical parameters up to this limit when mounted on a PCB with 2 oz. copper pad area per the recommended footprint.

Is SE15FDHM3/H pin-compatible with SE15FD-M3/H?

Yes, SE15FDHM3/H is physically pin-compatible with SE15FD-M3/H - both use the identical SMF (DO-219AB) package with anode/cathode terminals in the same location and orientation. However, SE15FDHM3/H adds AEC-Q101 qualification, halogen-free composition, and enhanced whisker resistance (JESD 201 Class 2), while SE15FD-M3/H lacks automotive qualification and is intended for commercial/industrial use only.

What is the reverse recovery time (t_rr) specification for SE15FDHM3/H?

The SE15FDHM3/H has a typical reverse recovery time (t_rr) of 900 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value is confirmed in the Vishay datasheet (Document Number: 87723, Rev. 13-May-2020) and supports use in moderate-frequency rectification up to ~500 kHz, where faster recovery reduces switching losses compared to general-purpose rectifiers like 1N4007.

Does SE15FDHM3/H meet J-STD-020 moisture sensitivity requirements?

Yes, SE15FDHM3/H meets J-STD-020 Moisture Sensitivity Level (MSL) 1, meaning it has unlimited floor life and may be subjected to reflow soldering without prior baking. This is enabled by its molding compound and terminal plating system, and is validated per the manufacturer's qualification report referenced in the datasheet. MSL Level 1 simplifies handling and assembly for high-volume SMT lines.

What does the "HM3" suffix indicate in SE15FDHM3/H?

The "HM3" suffix in SE15FDHM3/H denotes halogen-free, RoHS-compliant construction with full AEC-Q101 qualification. Specifically: "H" indicates AEC-Q101 qualification and enhanced whisker resistance (JESD 201 Class 2); "M3" indicates halogen-free and RoHS-compliant materials. This distinguishes it from base "M3" variants (e.g., SE15FD-M3/H), which lack automotive qualification despite sharing electrical and mechanical specs.
