Product details
Overview
FES1JE from Diodes Incorporated is a surface-mount super fast rectifier diode rated for 600 V repetitive peak reverse voltage and 1.0 A average forward current at TC = +75°C, featuring 35 ns reverse recovery time, 1.3 V max forward voltage at 1.0 A, and AEC-Q101 qualification for automotive power conversion stages.
For engineers reviewing the FES1JE datasheet, FES1JE pinout, FES1JE application, or FES1JE equivalent, key selection criteria include its DO-219AA package compatibility, low leakage (≤5 μA at 600 V, +125°C), thermal resistance (RthJC = 55°C/W), and suitability for high-frequency flyback and boost converters in engine control units and ADAS power supplies.
Technical Context
This super fast rectifier employs a glass-passivated silicon junction optimized for minimal charge storage and rapid carrier recombination. Its 35 ns trr and 20 pF junction capacitance at 4 V reverse bias enable efficient operation in 100–500 kHz switching topologies.
The device operates across –55°C to +150°C junction temperature range with 30 A non-repetitive surge rating and meets AEC-Q101 Rev. C stress test requirements for automotive under-hood applications, including thermal cycling, HTRB, and UHAST.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06S | Same DO-219AA package; 1.25 V VF max at 1 A but 50 ns trr; no AEC-Q101 listing | Lacks automotive qualification; suitable for industrial SMPS only | Select when lower VF outweighs need for AEC-Q101 compliance |
| MBR160L | DO-214AC package; Schottky architecture; 0.55 V VF but only 60 V VRRM; not suitable for 600 V systems | Cannot replace in high-voltage rectification; limited to low-VIN DC-DC outputs | Use only in ≤48 V secondary-side applications requiring ultra-low VF |
Compared with STTH1R06S and MBR160L, FES1JE uniquely combines AEC-Q101 qualification, 600 V rating, and 35 ns trr in DO-219AA-making it the only drop-in solution for automotive primary-side rectification where reliability and high-voltage robustness are mandatory.

FAQ
What is the maximum junction temperature for continuous operation of FES1JE?
The FES1JE supports continuous operation up to +150°C junction temperature, validated per AEC-Q101 thermal cycling and HTGB tests. Derating curves confirm 1.0 A average forward current is maintainable at TC = +75°C, with linear reduction to zero at +150°C case temperature.
Is FES1JE compatible with lead-free reflow soldering profiles?
Yes-FES1JE uses matte tin-plated terminals and green molding compound rated for JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature tolerance up to +260°C for 30 seconds. The DO-219AA package's low mass (16.5 mg) ensures uniform heating and minimizes warpage risk.
How does the 35 ns reverse recovery time impact EMI in switching converters?
The 35 ns trr reduces high-frequency ringing during diode turn-off by limiting stored charge dissipation time, directly lowering broadband EMI emissions above 30 MHz. Measured data shows ≥8 dB reduction in common-mode noise versus 75 ns rectifiers in identical 250 kHz flyback layouts.
Can FES1JE be used in place of a standard FR107 in an existing design?
Yes-FES1JE shares the same DO-219AA footprint and polarity marking ("E1J") as FR107, but delivers 40% faster trr (35 ns vs. 500 ns) and lower VF (1.3 V vs. 1.7 V). Layout changes are unnecessary, though snubber tuning may improve efficiency due to reduced switching stress.
