Product details
Overview
SE15FJHM3/H from Vishay General Semiconductor is a surface-mount standard rectifier diode with single configuration, 600 V maximum repetitive peak reverse voltage (VRRM), 1.5 A average forward current (IF(AV)), and low forward voltage drop of 0.86 V at 1.5 A and 125 °C. It is AEC-Q101 qualified, halogen-free, RoHS-compliant, and used in automotive power line polarity protection circuits.
For engineers reviewing the SE15FJHM3/H datasheet, SE15FJHM3/H pinout, SE15FJHM3/H application, or SE15FJHM3/H equivalent, this page delivers verified electrical ratings, thermal performance data, SMF (DO-219AB) package details, and validated alternative parts for commercial, industrial, and automotive power rectification designs.
Technical Context
This device is a silicon planar junction standard rectifier optimized for high-temperature operation up to 175 °C junction temperature, with 30 A non-repetitive surge capability and 900 ns typical reverse recovery time. Its low leakage current (5 μA at 25 °C) and 10.5 pF junction capacitance support stable DC blocking in medium-frequency switching environments.
The SMF (DO-219AB) package provides MSL level 1 moisture sensitivity, wave and reflow solder compatibility, and 20 °C/W junction-to-mount thermal resistance - enabling reliable thermal transfer in compact PCB layouts with 2 oz copper pads.

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/H | Same die, identical electrical specs; differs only in packaging suffix (no HM3 AEC-Q101 marking) | Lacks AEC-Q101 qualification documentation and traceability for automotive use | Select when AEC-Q101 is not required and cost optimization is prioritized |
| ON Semiconductor MUR160HE3/45 | Higher VRRM (600 V), same IF(AV) (1.5 A), but VF = 1.05 V at 25 °C and trr = 75 ns - faster but less efficient at high temperature | Better suited for higher-frequency flyback snubbers; less optimal for thermally limited automotive mounts | Select when fast recovery is critical and thermal headroom exceeds 25 °C above ambient |
Compared with SE15FJ-M3/H and MUR160HE3/45, the SE15FJHM3/H uniquely combines AEC-Q101 qualification, 0.86 V VF at 125 °C, and 20 °C/W RθJM - making it the preferred choice for space-constrained, high-temperature automotive rectification where long-term reliability is mandatory.

FAQ
What is the maximum junction temperature rating for SE15FJHM3/H?
The SE15FJHM3/H has a maximum junction temperature (TJ max.) of 175 °C, confirmed in the Vishay datasheet Document Number 87723. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial settings without active cooling. The SE15FJHM3/H maintains specified electrical parameters up to this limit when mounted on a recommended 2 oz copper PCB pad.
Is SE15FJHM3/H pin-compatible with other devices in the SE15F series?
Yes - all SE15F series devices, including SE15FJHM3/H, share the identical SMF (DO-219AB) package outline and anode/cathode terminal arrangement. Mechanical dimensions, footprint, and soldering profile are fully interchangeable across SE15FD, SE15FG, and SE15FJ variants. The SE15FJHM3/H differs only in its 600 V VRRM rating and AEC-Q101 qualification status.
Does SE15FJHM3/H meet automotive qualification standards?
Yes, SE15FJHM3/H is explicitly AEC-Q101 qualified, as stated in the Vishay datasheet and indicated by the "HM3" suffix. It passes human body model ESD testing (>8 kV), thermal cycling, and high-temperature operating life tests required for automotive electronics. This qualification applies specifically to the SE15FJHM3/H variant, not to non-HM3 versions like SE15FJ-M3/H.
What is the forward voltage drop of SE15FJHM3/H at elevated temperature?
The SE15FJHM3/H exhibits a forward voltage drop of 0.86 V at 1.5 A and 125 °C, per the Vishay datasheet's ELECTRICAL CHARACTERISTICS table. At 25 °C, VF is 0.96 V (typical). This positive temperature coefficient helps balance current sharing in parallel configurations and reduces thermal runaway risk in the SE15FJHM3/H.
What packaging format is supplied for SE15FJHM3/H?
SE15FJHM3/H is supplied in 7-inch diameter plastic tape and reel format, with a base quantity of 3000 units per reel. The "H" in the part number denotes this packaging option, and the "HM3" suffix confirms halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. Tape-and-reel packaging supports automated SMT placement compatible with industry-standard feeders.
