Product details
Overview
SE20NJHM3/I from Vishay General Semiconductor is a surface-mount standard rectifier diode in DFN3820A package, rated for 600 V repetitive peak reverse voltage (VRRM), 2 A average forward current (IF(AV)), and 32 A non-repetitive surge current (IFSM). It features low forward voltage drop (0.86 V at 2 A, 125 °C), <0.1 μA typical reverse leakage at 25 °C, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SE20NJHM3/I datasheet, SE20NJHM3/I pinout, SE20NJHM3/I application, or SE20NJHM3/I equivalent, this device is selected for high-reliability polarity protection in constrained PCB spaces where thermal performance, AOI compatibility, and automotive-grade reliability are critical design requirements.
Technical Context
This single-diode rectifier uses oxide planar chip junction technology and is optimized for general-purpose and rail-to-rail protection in consumer, industrial, and automotive power rails. Its DFN3820A package provides side-wettable flanks for automated optical inspection and supports reflow soldering per J-STD-020 MSL level 1 (260 °C peak).
The device operates across –55 °C to +175 °C junction temperature range with RθJA = 135 °C/W (typ.) on 2 oz. FR4, and exhibits 1200 ns typical reverse recovery time (trr) under IF = 0.5 A, IR = 0.1 A, Irr = 0.25 A conditions - confirming standard (non-fast) recovery behavior suitable for line-frequency rectification.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SE20NJ-M3/I | Same electrical specs, identical DFN3820A package, but not AEC-Q101 qualified | Limited to industrial/consumer use; unsuitable for automotive qualification programs | Select when AEC-Q101 is not required and cost sensitivity outweighs automotive compliance |
| SB260-TB-E3 | DO-214AA package, 600 V VRRM, 2 A IF(AV), VF = 0.85 V @ 2 A, but no side-wettable flanks or AEC-Q101 rating | Requires larger PCB area and manual AOI/X-ray for solder joint verification | Choose only if legacy through-hole or SMB footprint compatibility is mandatory |
Compared with SE20NJ-M3/I and SB260-TB-E3, the SE20NJHM3/I uniquely combines AEC-Q101 qualification, AOI-ready side-wettable flanks, and industry-leading 0.88 mm profile - making it the only option that satisfies automotive production traceability, automated inspection, and space-constrained packaging simultaneously.

FAQ
What is the maximum junction temperature rating for the SE20NJHM3/I?
The SE20NJHM3/I has a maximum operating junction temperature of +175 °C, validated per AEC-Q101 stress testing. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial enclosures. The device maintains specified electrical characteristics up to this limit when thermal design adheres to the recommended DFN3820A mounting pad layout and accounts for RθJA = 135 °C/W (typ.) on 2 oz. FR4.
Does the SE20NJHM3/I have AEC-Q101 qualification, and what does the 'H' suffix indicate?
Yes, the SE20NJHM3/I is AEC-Q101 qualified - the 'H' in the part number explicitly denotes this automotive-grade qualification per the Vishay ordering code structure. This certification covers stress tests including HBM ESD (>8 kV), temperature cycling, and high-temperature operating life, confirming suitability for automotive powertrain, body, and infotainment systems where reliability is mission-critical.
What is the forward voltage drop of the SE20NJHM3/I at 2 A and 125 °C?
The SE20NJHM3/I exhibits a forward voltage drop of 0.86 V at 2 A and 125 °C junction temperature, as specified in the Vishay datasheet (Document Number 98367). This value reflects real-world conduction loss under elevated thermal conditions and is critical for calculating power dissipation and thermal margin in high-temperature applications such as automotive ECUs.
How does the DFN3820A package of the SE20NJHM3/I support automated optical inspection (AOI)?
The DFN3820A package of the SE20NJHM3/I features side-wettable flanks - exposed metal on the vertical edges of the terminals - enabling AOI systems to verify solder fillet formation without requiring X-ray inspection. This design meets IPC-A-610 Class 2 requirements and reduces post-SMT defect escape rates in high-volume automotive and industrial manufacturing lines.
What is the reverse recovery time (trr) specification for the SE20NJHM3/I, and what does it imply for circuit use?
The SE20NJHM3/I has a typical reverse recovery time (trr) of 1200 ns under IF = 0.5 A, IR = 0.1 A, and Irr = 0.25 A test conditions. This confirms its classification as a standard (not fast or ultrafast) recovery rectifier, making it appropriate for 50/60 Hz line-frequency rectification and low-switching-frequency DC-DC inputs - but not recommended for high-frequency (>100 kHz) SMPS primary-side rectification where faster trr is required.
