Product details
Overview
FR103G A0G from Taiwan Semiconductor is a 1A, 200V fast recovery rectifier diode in DO-204AL (DO-41) package, featuring 150 ns reverse recovery time, 1.3 V max forward voltage at 1 A, and 30 A surge current capability. It is used in switching-mode power supplies and DC-DC converters where efficiency and thermal reliability are critical.
For engineers reviewing the FR103G A0G datasheet, FR103G A0G pinout, FR103G A0G application, or FR103G A0G equivalent, key selection criteria include repetitive peak reverse voltage (200 V), forward voltage drop, thermal resistance (70 °C/W), and AEC-Q101 qualification availability across the family.
Technical Context
This discrete silicon rectifier uses a glass-passivated junction for enhanced moisture and contamination resistance, enabling stable operation in automotive and industrial environments. Its single-die configuration supports unidirectional conduction with cathode-band polarity marking and pure tin-plated leads compliant with J-STD-002 solderability.
The device operates over –55 °C to +150 °C junction temperature range and delivers low power loss via 1.3 V max VF at rated current. Reverse leakage remains ≤5 µA at 25 °C and ≤100 µA at 125 °C under rated VR, supporting high-efficiency designs in thermally constrained layouts.
Key Specifications

| trr | 150 ns - fast recovery enables high-frequency switching up to ~1 MHz |
| RθJA | 70 °C/W - thermal resistance from junction to ambient, defining heatsinking needs |
| VF (max) | 1.3 V @ 1 A, 25 °C - directly impacts conduction loss and system efficiency |

Use Value: AEC-Q101-qualified variants (e.g., FR103GH) meet automotive qualification requirements for mission-critical subsystems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R02U (STMicroelectronics) | Same 1 A / 200 V rating; 125 ns trr; TO-220AC package (larger, higher thermal mass) | Preferred where board space allows and higher thermal dissipation is needed | Select when higher surge robustness or heatsink-mounting is required |
| 1N4934 (ON Semiconductor) | 1 A / 200 V; 200 ns trr; DO-41 package; no AEC-Q101 option | Suitable for cost-sensitive consumer or industrial non-automotive use | Choose for legacy compatibility or where AEC-Q101 is not mandated |
Compared with STTH1R02U and 1N4934, FR103G A0G offers optimal balance of speed (150 ns), DO-41 footprint, and AEC-Q101 availability in the FRxG family-making it ideal for space-constrained automotive auxiliary supplies and industrial SMPS where qualification and thermal performance intersect.

FAQ
What is the maximum junction temperature rating for FR103G A0G?
The FR103G A0G has a maximum junction temperature (TJMAX) of +150 °C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version H2104). This rating enables reliable operation in sealed enclosures or high-ambient environments when derated per the forward current derating curve. Thermal design must respect the 70 °C/W junction-to-ambient resistance to avoid exceeding this limit under full load.
Does FR103G A0G have AEC-Q101 qualification?
No-FR103G A0G is not AEC-Q101 qualified. However, the FR103GH variant (same electrical specs, tape-and-reel packaging) is explicitly qualified per AEC-Q101. The "H" suffix denotes qualification; "A0G" indicates ammo-box packaging without qualification. For automotive applications requiring AEC-Q101, FR103GH is the direct functional alternative with identical VRRM, trr, and IF.
What is the reverse recovery time (trr) of FR103G A0G and how is it measured?
The FR103G A0G has a reverse recovery time (trr) of 150 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the Taiwan Semiconductor datasheet. This value reflects the time required for minority carriers to clear after forward conduction ceases, directly impacting switching losses in high-frequency converters. It is validated using the test circuit shown in Figure 6 of the datasheet.
Can FR103G A0G replace FR102G or FR104G in an existing design?
FR103G A0G can replace FR102G (100 V) only if the circuit's peak reverse voltage stays below 200 V-providing additional margin but requiring verification of layout thermal limits. It cannot safely replace FR104G (400 V) in circuits exposed to >200 V reverse stress. Voltage rating is not backward-compatible; always confirm VRRM exceeds worst-case transient voltage by ≥20% in the target application.
What does the "A0G" suffix mean in FR103G A0G?
The "A0G" suffix in FR103G A0G indicates ammo-box packaging: 3,000 units per box, DO-204AL (DO-41) package, green molding compound. It distinguishes packaging from tape-and-reel versions (e.g., FR103G = 5,000/reel). "A0" specifies ammo format; "G" confirms RoHS-compliant, halogen-free compound per IEC 61249-2-21-no functional or electrical difference from FR103G.
