Product details
Overview
FS1ME-7 from Diodes Incorporated is a 1.0A, 1000V surface-mount standard recovery rectifier in DO-219AA package, featuring 1.1V max forward voltage at 1A and 5µA max reverse leakage at 1000V/25°C, optimized for AC-to-DC power conversion in compact wall adapters and USB-C chargers.
For engineers reviewing the FS1ME-7 datasheet, FS1ME-7 pinout, FS1ME-7 application, or FS1ME-7 equivalent, key selection criteria include its 1000V peak repetitive reverse voltage, 1A average rectified current rating, low-profile DO-219AA footprint, thermal resistance of 45°C/W junction-to-lead, and suitability for space-constrained consumer power supplies requiring RoHS-compliant, halogen-free construction.
Technical Context
The FS1ME-7 employs a glass-passivated silicon die to achieve stable reverse blocking up to 1000V and controlled standard recovery behavior with tRR of 1000–1600ns under IF = 0.5A / IR = 1.0A conditions. Its low VF (0.8–1.1V) reduces conduction loss in low-frequency rectification circuits.
Thermally, it delivers RθJL = 45°C/W and RθJC = 53°C/W on a standard glass-epoxy PCB pad, enabling reliable operation from –55°C to +150°C. The DO-219AA package supports automated placement and reflow while maintaining mechanical robustness and moisture sensitivity level 1 compliance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS1H100S | 1A/1000V Schottky; VF ≈ 0.85V but VR ≈ 100V lower; higher IR at elevated temperature | Not suitable for 1000V line-survival requirements; limited to lower-voltage DC-DC inputs | Select only if system operates below 900V reverse stress and prioritizes ultra-low VF over surge margin |
| 1N4007G | 1A/1000V standard recovery in DO-41; larger footprint (5.2mm L × 2.7mm D); RθJA ≈ 65°C/W | Requires through-hole assembly; incompatible with fully SMT production lines | Choose only for legacy through-hole designs where board real estate and thermal performance are secondary |
Compared with STPS1H100S and 1N4007G, the FS1ME-7 uniquely combines 1000V rating, 1A capability, DO-219AA SMT compatibility, and 45°C/W junction-to-lead thermal resistance-making it optimal for modern, height-sensitive, high-volume AC/DC converters.

FAQ
What is the maximum junction temperature for continuous operation of the FS1ME-7?
The FS1ME-7 is rated for continuous operation from –55°C to +150°C junction temperature. At 1A DC load and 25°C ambient, junction temperature rise is approximately 68°C (1A² × 45°C/W), well within safe limits. Derating is required above 125°C ambient per the datasheet's thermal curves.
Can the FS1ME-7 be used in place of a 1N4007 in an existing design?
Yes, electrically-both have 1000V VRRM and 1A IO-but the FS1ME-7 uses DO-219AA SMT packaging versus DO-41 through-hole. Layout redesign and reflow profile validation are required; thermal performance improves due to lower RθJL (45 vs ~65°C/W), but surge rating (IFSM = 30A) matches the 1N4007.
Does the FS1ME-7 meet AEC-Q101 for automotive use?
No-the FS1ME-7 is commercially qualified (not AEC-Q101). Diodes offers automotive-grade variants like the FS1MEQ-7 with PPAP documentation and IATF 16949 manufacturing, but the -7 suffix denotes commercial grade. Automotive designs require explicit qualification confirmation from Diodes.
What is the reverse recovery time measurement condition for the FS1ME-7?
tRR is measured under IF = 0.5A, IR = 1.0A, and IRR = 0.25A per JEDEC standards. The specified range is 1000–1600ns, reflecting standard recovery behavior appropriate for 50/60Hz line-frequency rectification-not high-frequency switching applications.
