Product details
Overview
FR105G A0G from Taiwan Semiconductor is a 1A, 600V fast recovery rectifier diode in DO-204AL (DO-41) package, featuring 250 ns reverse recovery time, 1.3 V max forward voltage at 1 A, and 30 A surge capability - used in DC-DC converters and switching inverters for high-efficiency power conversion.
For engineers reviewing the FR105G A0G datasheet, FR105G A0G pinout, FR105G A0G application, or FR105G A00G equivalent, key selection criteria include repetitive peak reverse voltage (600 V), thermal resistance (70 °C/W), junction temperature range (–55 to +150 °C), RoHS/halogen-free compliance, and DO-41 mechanical compatibility with standard through-hole PCB layouts.
Technical Context
This device operates as a single-die, unidirectional fast recovery rectifier optimized for high-frequency switching power supplies. Its glass-passivated junction ensures stable performance under thermal cycling, while the pure tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.
The FR105G A0G delivers low conduction loss (VF ≤ 1.3 V @ 1 A, 25°C) and controlled reverse recovery (trr = 250 ns @ IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A), enabling efficient operation in SMPS topologies where di/dt and EMI management are critical.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06U | 1 A, 600 V, trr = 150 ns, TO-220AC package, VF = 1.15 V typ | Higher thermal mass; requires heatsink above 0.5 A continuous; not DO-41 drop-in | Prefer when lower VF and faster trr justify PCB real estate and thermal design overhead |
| ON Semi MUR1060 | 1 A, 600 V, trr = 35 ns, DO-41, VF = 1.7 V max, AEC-Q101 qualified | Ultra-fast but higher VF increases conduction loss; same footprint | Choose for ultra-low-noise or high-frequency (>300 kHz) designs where trr dominates loss budget |
Compared with STTH1R06U and MUR1060, the FR105G A0G balances cost, thermal performance, and layout simplicity in space-constrained 100–200 kHz SMPS - offering optimal VF/trr trade-off in DO-41 without heatsink dependency or premium ultra-fast pricing.

FAQ
What is the maximum repetitive peak reverse voltage rating for FR105G A0G?
The FR105G A0G has a maximum repetitive peak reverse voltage (VRRM) of 600 V. This rating is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version H2104). It defines the highest reverse voltage the FR105G A0G can block repeatedly without breakdown under normal operating conditions, making it suitable for 400 VAC-derived DC bus applications with safety margin.
Is FR105G A0G RoHS and halogen-free compliant?
Yes, the FR105G A0G is RoHS compliant and halogen-free per IEC 61249-2-21. This is explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. The halogen-free status applies to the molding compound, and RoHS compliance covers all restricted substances - critical for export to EU and other regulated markets where FR105G A0G is deployed in end equipment.
What is the reverse recovery time (trr) of FR105G A0G, and under what test conditions?
The reverse recovery time (trr) of FR105G A0G is 250 ns, measured under the conditions: IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is specified in the ELECTRICAL SPECIFICATIONS table of the official datasheet. It reflects the diode's speed in transitioning from conduction to blocking state - a key parameter affecting switching loss and EMI in high-frequency power converters using FR105G A0G.
Does FR105G A0G have AEC-Q101 qualification?
No, FR105G A0G is not AEC-Q101 qualified. Only variants marked with "H" suffix (e.g., FR105GH or FR105GHA0G) carry AEC-Q101 qualification, as noted in the ORDERING INFORMATION section. The FR105G A0G uses the standard green compound and ammo box packaging but lacks automotive-grade stress testing certification - appropriate for industrial and commercial applications, not automotive ECUs.
What is the thermal resistance from junction to ambient (RθJA) for FR105G A0G in its DO-41 package?
The junction-to-ambient thermal resistance (RθJA) for FR105G A0G is 70 °C/W, as published in the THERMAL PERFORMANCE section of the Taiwan Semiconductor datasheet. This value assumes standard mounting on FR-4 PCB with no added heatsink and is used to estimate junction temperature rise under steady-state conduction - essential for thermal design validation when using FR105G A0G in enclosed power supplies.
