Product details

Overview

SE15FJHM3/I from Vishay General Semiconductor is a surface-mount standard rectifier diode with single configuration, 600 V maximum repetitive peak reverse voltage (V_RRM), 1.5 A average forward current (I_F(AV)), and low 0.86 V forward voltage at 1.5 A and 125 °C - used for power line polarity protection in automotive and industrial DC power supplies.

For engineers reviewing the SE15FJHM3/I datasheet, SE15FJHM3/I pinout, SE15FJHM3/I application, or SE15FJHM3/I equivalent, key selection criteria include its AEC-Q101 qualification, SMF (DO-219AB) package compatibility, 175 °C max junction temperature, and 900 ns typical reverse recovery time in high-reliability rectification circuits.

Technical Context

This device is a silicon planar junction standard rectifier optimized for unidirectional current conduction in medium-voltage DC power rails. It features oxide planar chip construction, matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102, and meets MSL level 1 per J-STD-020 with 260 °C reflow peak.

The SE15FJHM3/I operates across -55 °C to +175 °C junction temperature range and delivers 5 μA max reverse leakage at rated V_RRM and 25 °C, with thermal resistance R_θJA = 130 °C/W and R_θJM = 20 °C/W - enabling compact thermal design in space-constrained SMT layouts.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay SE15FJ-M3/I	No AEC-Q101 qualification; same electrical specs and SMF package	Suitable for commercial/industrial use only; not approved for automotive deployment	Select when AEC-Q101 is not required and cost optimization is primary
ON Semiconductor MUR160G	Higher V_RRM (600 V), same I_F(AV) (1.5 A), but TO-220AC package (larger, through-hole)	Requires PCB redesign; better thermal dissipation but incompatible with SMT-only lines	Choose only if board-level thermal constraints exceed SMF capability and through-hole assembly is available

Compared with SE15FJ-M3/I, the SE15FJHM3/I adds AEC-Q101 qualification without altering electrical performance - making it the sole drop-in automotive option in this family. Against MUR160G, it trades thermal headroom for SMT scalability and footprint reduction, requiring no layout change but demanding tighter thermal management.

FAQ

What is the maximum junction temperature rating for SE15FJHM3/I?

The SE15FJHM3/I has a maximum junction temperature (T_J max) of +175 °C, validated per AEC-Q101 test conditions. This rating allows reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves in the Vishay datasheet (Document 87723) define safe I_F(AV) limits above 125 °C ambient. The SE15FJHM3/I maintains 0.86 V forward voltage at 125 °C junction, supporting thermal stability in sustained-load applications.

Is SE15FJHM3/I pin-compatible with SE15FJ-M3/I?

Yes - SE15FJHM3/I and SE15FJ-M3/I share identical SMF (DO-219AB) package dimensions, pinout, and terminal configuration (anode/cathode). The only difference is AEC-Q101 qualification and halogen-free/RoHS compliance in the HM3 suffix. No PCB layout change is needed when upgrading from SE15FJ-M3/I to SE15FJHM3/I in automotive designs requiring qualification.

What does the "HM3" suffix indicate in SE15FJHM3/I?

The "HM3" suffix in SE15FJHM3/I denotes halogen-free, RoHS-compliant construction with full AEC-Q101 qualification. Per Vishay's ordering documentation, HM3 parts meet JESD201 Class 2 whisker testing and MSL Level 1 moisture sensitivity. This distinguishes SE15FJHM3/I from base M3 variants (halogen-free/RoHS only) and non-HM3 versions (e.g., SE15FJ-M3/I), confirming its suitability for automotive production.

Does SE15FJHM3/I support reflow soldering with lead-free profiles?

Yes - SE15FJHM3/I is rated for lead-free reflow soldering with a maximum peak temperature of 260 °C per J-STD-020 MSL Level 1. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 solderability standards. The device also supports wave soldering. Thermal resistance values (R_θJA = 130 °C/W, R_θJM = 20 °C/W) are specified for recommended 2 oz. copper pad layouts per Vishay's footprint guide.

What is the typical reverse recovery time (t_rr) of SE15FJHM3/I and how does it affect circuit performance?

The SE15FJHM3/I has a typical reverse recovery time (t_rr) of 900 ns under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A test conditions. This value impacts switching losses and EMI generation in moderately fast rectification circuits (e.g., <100 kHz flyback outputs). While slower than fast recovery or Schottky diodes, the t_rr is well-suited for general-purpose and line-frequency applications where cost, ruggedness, and V_RRM outweigh ultra-fast switching needs.
