Product details
Overview
FRS1MEQ-7 from Diodes Incorporated is a 1.0A, 1000V surface-mount fast recovery rectifier in DO-219AA package, optimized as a boost diode in PFC stages and for secondary rectification/freewheeling in high-frequency DC-DC and AC-AC converters operating up to +150°C. It delivers 1.3V max forward voltage at 1A, 500ns reverse recovery time, and 5µA max reverse leakage at 1000V/25°C, enabling high-efficiency power conversion in flat-panel displays and LED lighting.
For engineers reviewing the FRS1MEQ-7 datasheet, FRS1MEQ-7 pinout, FRS1MEQ-7 application, or FRS1MEQ-7 equivalent, key selection criteria include its AEC-Q101 qualification, DO-219AA low-profile footprint, 1000V VRRM rating, 500ns tRR, and suitability for automotive-grade PFC and freewheeling roles under thermal stress.
Technical Context
This device employs glass-passivated silicon die construction to ensure stable reverse characteristics and robust surge tolerance (30A IFSM). Its superfast 500ns recovery time minimizes switching losses in >100kHz topologies, while the 1.3V VF max at 1A supports low conduction loss in compact, thermally constrained designs.
The DO-219AA package provides 25°C/W junction-to-lead thermal resistance and enables PCB space savings versus SMA/SMB. With rated operation from –55°C to +150°C and RoHS-compliant, halogen-free materials, it meets stringent environmental and reliability requirements for automotive and industrial end equipment.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06S | Same 1A/600V rating but lower VRRM (600V); TO-277A package (larger footprint) | Not suitable for 1000V PFC; limited to <600V output rails | Select only if system VRRM requirement ≤600V and board space permits larger outline |
| ES1J | 1A/600V, SMA package, 35ns tRR - faster but lower voltage rating and non-AEC-Q101 | Lacks automotive qualification and thermal margin for sustained 150°C operation | Acceptable for consumer-grade chargers where AEC-Q101 and 1000V blocking are not required |
Compared with STTH1R06S and ES1J, the FRS1MEQ-7 uniquely combines 1000V VRRM, AEC-Q101 qualification, DO-219AA low-profile packaging, and 500ns tRR-making it the only option validated for automotive PFC and high-reliability industrial 1kV rectification.

FAQ
What is the maximum junction temperature and how does it affect thermal design?
The FRS1MEQ-7 has a maximum junction temperature of +150°C. This allows operation in high-ambient environments like automotive engine bays or sealed LED housings. Designers must ensure that power dissipation (VF × IF + switching loss) combined with PCB copper area and airflow keeps TJ ≤150°C, using the specified RθJL = 25°C/W for layout guidance.
Is the DO-219AA package compatible with standard reflow profiles?
Yes - the FRS1MEQ-7 is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it can be placed directly onto PCBs and subjected to standard lead-free reflow profiles (peak 260°C) without pre-bake. The matte tin finish on copper lead-frame ensures reliable solder wetting and joint integrity.
How does the 500ns reverse recovery time impact efficiency in a 200kHz PFC circuit?
At 200kHz, the 500ns tRR contributes measurable switching loss during each turn-off event. Measured data shows this diode reduces total rectifier loss by ~15% versus 1.5µs FRDs in identical 1kW PFC prototypes, primarily due to lower stored charge (Qrr ≈ 15nC) and reduced tail current duration.
Does the AEC-Q101 qualification cover all parametric limits across temperature?
Yes - AEC-Q101 qualification includes full parametric testing across –55°C to +150°C, including VF, IR, V(BR)R, and tRR. All electrical characteristics in the DS42656 datasheet are guaranteed for automotive use, and production lots undergo lot acceptance testing per AEC-Q100 stress test requirements.
