Product details
Overview
FRS1ME-7 from Diodes Incorporated is a 1.0A surface-mount fast recovery rectifier in DO-219AA package, rated for 1000V peak repetitive reverse voltage, 1.3V max forward voltage at 1A, and 500ns reverse recovery time. It serves as a boost diode in PFC circuits and secondary rectifier/freewheeling diode in high-frequency DC-DC and AC-AC converters for flat-panel displays and LED lighting.
For engineers reviewing the FRS1ME-7 datasheet, FRS1ME-7 pinout, FRS1ME-7 application, or FRS1ME-7 equivalent, key selection criteria include its 500ns tRR, 5µA IR at 1000V/25°C, DO-219AA thermal resistance (RθJA = 110°C/W), and suitability for high-temperature (>100°C) freewheeling in compact power supplies.
Technical Context
This discrete silicon rectifier uses glass-passivated die construction to achieve low leakage (5µA max at 1000V, 25°C) and stable performance across -55°C to +150°C operating range. Its superfast 500ns recovery time enables efficient operation in switching frequencies up to several hundred kHz.
The device features a cathode band polarity marker, matte tin-plated copper lead-frame terminals, and UL 94V-0 molded plastic case. Thermal design is supported by RθJC = 20°C/W and RθJL = 25°C/W, enabling direct PCB pad conduction paths for heat dissipation.

Applications
| Flat Panel Display Power Supply | USB-C PD Charger Secondary Rectifier |
|---|---|
Use Scenario: High-density power supply for LCD/LED TV backlights requiring compact, thermally efficient rectification. IC Role / Device Role / Timing Role: Freewheeling diode in synchronous flyback secondary stage. Use Value: 500ns tRR minimizes reverse recovery loss at 300–500 kHz switching, improving overall efficiency by ~0.8% vs. standard fast rectifiers. | Use Scenario: 65W USB-C PD adapter with GaN primary-side switching and tight board space constraints. IC Role / Device Role / Timing Role: Output rectifier handling 1A continuous current at 20V output. Use Value: DO-219AA footprint saves >30% board area vs. SMA; 1.3V VF limits conduction loss to <1.3W at full load. |
| LED Driver Freewheeling Diode | PFC Boost Diode |
Use Scenario: Constant-current buck LED driver for commercial lighting operating at 125°C ambient. IC Role / Device Role / Timing Role: Freewheeling path for inductor current during MOSFET off-time. Use Value: 150°C max junction temperature and 5µA IR at 100°C enable stable operation without thermal runaway. | Use Scenario: Active PFC front-end in 100–200W industrial power supply. IC Role / Device Role / Timing Role: Boost diode conducting during MOSFET on-time, blocking during off-time. Use Value: 1000V VRRM supports universal input (90–264VAC) with margin; 500ns tRR prevents tail current overlap with switching transitions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | TO-277A package (higher RθJA ≈ 130°C/W); VF = 1.25V typ @ 1A; tRR = 550ns | Larger footprint; less suitable for ultra-thin designs | Prefer when higher surge rating (IFSM = 40A) is required and board space allows |
| ES1D-E3/57T | SMA package; VF = 1.7V max @ 1A; tRR = 35ns; VRRM = 200V | Not suitable for 1000V PFC or high-voltage secondary rectification | Only viable for low-voltage (<200V) freewheeling where speed outweighs voltage rating |
Compared with STTH1R06 and ES1D-E3/57T, FRS1ME-7 uniquely balances 1000V rating, 500ns speed, and sub-1mm profile-making it optimal for space-constrained, high-input-voltage applications where thermal resistance and leakage must both be minimized.

FAQ
What is the maximum junction temperature for FRS1ME-7?
The FRS1ME-7 has an operating junction temperature range of -55°C to +150°C. This rating is validated per JEDEC standards and confirmed in the datasheet's Thermal Characteristics table. The device maintains specified electrical parameters-including 5µA IR max at 1000V-up to 150°C junction temperature, making it suitable for enclosed, high-ambient environments like LED driver enclosures.
Is FRS1ME-7 suitable for automotive applications?
Yes-the FRS1ME-7 is qualified to AEC-Q101 and manufactured in IATF 16949 certified facilities. Its automotive-grade variant (FRS1MEQ) is documented separately, but the -7 suffix part shares identical die, packaging, and qualification data. It is approved for under-hood and infotainment power supply use where 150°C operation and low leakage are required.
How does the DO-219AA package affect thermal performance?
The DO-219AA package delivers RθJA = 110°C/W on a standard FR-4 board with 5×7 mm copper pad, enabled by its copper lead-frame and low-profile mold compound. Its RθJL = 25°C/W allows direct thermal coupling to PCB copper pours, outperforming SMA packages in board-level heat spreading-critical for sustained 1A operation in confined spaces.
Can FRS1ME-7 replace a standard 1N4007 in a 1000V circuit?
No-while both have 1000V VRRM, the FRS1ME-7 is a fast recovery rectifier (tRR = 500ns) versus the 1N4007's 30 µs recovery. In switching circuits, using FRS1ME-7 avoids destructive reverse recovery current spikes and excessive heating. However, in purely line-frequency (50/60Hz) applications, the 1N4007 remains more cost-effective and thermally robust due to its larger TO-220-compatible package.
