Product details

Overview

SE15FDHM3/I from Vishay General Semiconductor is a surface-mount standard rectifier diode in the eSMP® Series, configured as a single anode-cathode 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/I datasheet, SE15FDHM3/I pinout, SE15FDHM3/I application, or SE15FDHM3/I equivalent, key selection criteria include its 175 °C maximum junction temperature, 30 A non-repetitive surge rating, 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 device implements a planar oxide junction structure optimized for low forward voltage drop and stable high-temperature operation up to 175 °C. Its thermal resistance of 130 °C/W (junction-to-ambient) and 20 °C/W (junction-to-mount) supports reliable performance in compact, thermally constrained PCB layouts.

The SE15FDHM3/I delivers fast switching behavior with a typical reverse recovery time of 900 ns under IF = 0.5 A / IR = 1.0 A conditions, and exhibits low junction capacitance (10.5 pF at 4.0 V, 1 MHz), making it suitable for moderate-frequency rectification where efficiency and EMI control are critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Maximum reverse blocking capability without breakdown; defines usable input voltage range in DC/DC and AC-DC front-end stages.
I_F(AV)	1.5 A - Continuous DC forward current rating at 75 °C mount temperature; determines steady-state power handling in linear regulators and battery chargers.
V_F @ 1.5 A, 125 °C	0.86 V - Low conduction loss at elevated temperature; reduces power dissipation and thermal stress in automotive under-hood applications.
I_R @ 25 °C	5 μA - Minimal reverse leakage; preserves system standby power budget and prevents unintended discharge in hold-up circuits.
t_rr	900 ns - Fast reverse recovery enables efficient operation up to ~100 kHz switching frequencies in flyback and buck-derived topologies.
T_J max.	175 °C - Extended junction temperature rating allows direct placement near heat sources (e.g., MOSFETs, inductors) without derating penalties.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay SE15FD-M3/I	No AEC-Q101 qualification; same V_RRM, I_F(AV), V_F, and package.	Suitable for commercial/industrial use only; not approved for automotive environments requiring AEC-Q101.	Select SE15FDHM3/I when automotive qualification, extended temperature validation, or enhanced ESD robustness (>8 kV HBM) is required.
ON Semiconductor MUR120RLG	Higher V_RRM (200 V same), but TO-220AC package (larger footprint, higher R_θJA = 50 °C/W), slower t_rr (~150 ns), and no AEC-Q101 rating.	Requires heatsinking and larger PCB area; limited to lower-power or less space-constrained designs.	Choose SE15FDHM3/I for SMT scalability, thermal efficiency in dense layouts, and automotive compliance-especially where board space and reliability are critical.

Compared with SE15FD-M3/I and MUR120RLG, the SE15FDHM3/I uniquely combines AEC-Q101 qualification, DO-219AB low-profile packaging, and 175 °C operation-enabling drop-in deployment in automotive modules and high-density industrial power supplies without layout or thermal redesign.

FAQ

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

The SE15FDHM3/I has a maximum junction temperature (T_J) rating of +175 °C, verified per AEC-Q101 stress testing. This allows sustained operation in high-ambient environments such as engine compartments or enclosed industrial enclosures without thermal derating. The SE15FDHM3/I maintains specified V_F and I_R performance up to this limit, supporting robust design margins in thermally demanding applications.

Is the SE15FDHM3/I pin-compatible with other variants in the SE15Fx family?

Yes-the SE15FDHM3/I shares identical SMF (DO-219AB) package dimensions and anode/cathode terminal layout with SE15FGHM3/I and SE15FJHM3/I. All three variants use the same footprint and solder pad pattern, enabling design reuse across 200 V, 400 V, and 600 V reverse voltage grades without PCB modification. The SE15FDHM3/I differs only in V_RRM and device marking (BD).

Does the SE15FDHM3/I meet automotive qualification standards?

Yes-the SE15FDHM3/I is fully AEC-Q101 qualified, including HTGB, HTRB, TCT, and ESD (H3B class >8 kV) testing. Its "HM3" suffix explicitly denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. This makes the SE15FDHM3/I suitable for safety-critical automotive subsystems such as body control modules, ADAS power supplies, and infotainment DC-DC converters.

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

The SE15FDHM3/I has a typical reverse recovery time (t_rr) of 900 ns, measured at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value is confirmed in the official Vishay datasheet (Doc. #87723). The SE15FDHM3/I's t_rr supports efficient operation in switch-mode power supplies operating below 100 kHz, minimizing switching losses and associated EMI generation.

How does the SE15FDHM3/I differ from the non-HM3 version (e.g., SE15FD-M3/I)?

The SE15FDHM3/I adds AEC-Q101 qualification, enhanced ESD robustness (>8 kV HBM), and full automotive-grade process controls versus the commercial-grade SE15FD-M3/I. Both share identical electrical specs (V_RRM, I_F(AV), V_F, t_rr) and SMF packaging-but only the SE15FDHM3/I is approved for automotive use per industry reliability standards. The HM3 suffix also confirms halogen-free and RoHS compliance.
