Product details
Overview
FS2MED-7 from Diodes Incorporated is a 2.0A surface-mount standard recovery rectifier in DO-219AA package, rated for 1000V peak repetitive reverse voltage, 1.1V max forward voltage at 2A/25°C, and 5µA max reverse leakage at 1000V/25°C; used in AC-to-DC power conversion stages of wall adapters and USB-C chargers.
For engineers reviewing the FS2MED-7 datasheet, FS2MED-7 pinout, FS2MED-7 application, or FS2MED-7 equivalent, key selection criteria include VRRM rating, thermal resistance (RθJA = 42°C/W), reverse recovery time (500–1000 ns), low-profile DO-219AA footprint, and AEC-Q200 readiness for automotive auxiliary power supplies.
Technical Context
This standard recovery rectifier operates with 500–1000 ns reverse recovery time under IF = 0.5A / IR = 1.0A conditions and delivers 2A average rectified output current with 18°C/W junction-to-case thermal resistance. Its glass-passivated die construction ensures stable performance across -55°C to +150°C operating range.
The device supports 1000V DC blocking capability and exhibits 12.3 pF typical junction capacitance at 4V/1MHz. Derating applies for capacitive loads (20% current reduction), and I²t rating is 20.75 A²s for 8.3ms surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands up to 1000V repetitive reverse voltage without breakdown in AC line input stages |
| IO | 2 A - Sustains continuous 2A average forward current in bridge or single-phase rectifier configurations |
| VF Max | 1.1 V @ 2A, 25°C - Limits conduction loss to ≤2.2W per diode at full load, reducing heatsink requirements |
| IR Max | 5 µA @ 1000V, 25°C - Ensures minimal standby power loss in high-impedance hold-up circuits |
| tRR | 500–1000 ns - Compatible with 50/60Hz line-frequency rectification; not suitable for high-frequency SMPS primary side |
| RθJA | 42 °C/W - Requires ≥20mm×20mm copper pad on FR-4 for safe 2A operation at ambient ≤70°C |
| Package | DO-219AA - 1.90mm × 2.80mm footprint with 0.60mm lead length; enables <0.8mm board profile in slim adapters |
Pinout & Package
DO-219AA is a two-terminal surface-mount package with cathode band marking. Terminals are matte tin-finished copper lead-frame; polarity is unambiguous via molded cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | AC input node connection | Accepts incoming AC waveform; must be routed with adequate creepage for 1000V isolation |
| Cathode | DC output node connection | Delivers rectified positive voltage; ties to bulk capacitor or downstream regulator input |
Key Features

Manufacturer
Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, with design, manufacturing, and sales operations across Asia, Europe, and North America.
The FS2MED-7 belongs to Diodes' standard recovery rectifier product line, engineered for cost-sensitive, thermally constrained AC/DC front-end applications where 50/60Hz line frequency operation and low-profile packaging are critical.
FAQ
What is the maximum allowable junction temperature for FS2MED-7?
The FS2MED-7 has an absolute maximum junction temperature of +150°C and a minimum storage temperature of -55°C. Operation above +150°C risks irreversible parametric shift or bond-wire failure. Thermal design must ensure TJ remains within this limit under worst-case ambient and load conditions using RθJA = 42°C/W and measured power dissipation.
Is FS2MED-7 suitable for use in a flyback converter primary rectifier?
No. FS2MED-7 is a standard recovery rectifier with 500–1000 ns reverse recovery time, making it unsuitable for high-frequency flyback primary-side rectification (typically >50 kHz). It is designed exclusively for 50/60 Hz line-frequency applications such as half-wave or full-wave rectifiers in offline AC/DC supplies.
Does FS2MED-7 have automotive qualification?
FS2MED-7 is offered in commercial grade (FS2MED-7), but Diodes provides AEC-Q200 qualification path, PPAP capability, and IATF 16949-certified manufacturing for automotive applications. Customers requiring qualified parts must contact Diodes or an authorized representative to initiate change control and qualification documentation.
How does the DO-219AA package compare to SMA in thermal performance?
DO-219AA offers lower thermal resistance than SMA: RθJC = 18°C/W vs. ~25°C/W for SMA, due to shorter internal lead-frame path and optimized die attach. This allows FS2MED-7 to sustain 2A continuously with less board-level copper area than SMA-packaged equivalents, critical in ultra-thin power adapters.
