Product details
Overview
FR104G B0G from Taiwan Semiconductor is a 1A, 400V 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 - used in switching-mode DC/DC converters requiring efficient unidirectional conduction.
For engineers reviewing the FR104G B0G datasheet, FR104G B0G pinout, FR104G B0G application, or FR104G B0G equivalent, key selection criteria include repetitive peak reverse voltage (400 V), thermal resistance (70 °C/W), junction temperature range (–55 to +150 °C), RoHS/halogen-free compliance, and AEC-Q101 qualification status of variant codes.
Technical Context
This single-die, glass-passivated fast recovery rectifier delivers low forward voltage drop and high reliability for high-frequency switching applications. Its 150 ns trr enables reduced switching losses in SMPS topologies operating up to several hundred kHz.
The device uses pure tin-plated leads compliant with J-STD-002 and meets JESD201 Class 2 whisker resistance. Polarity is marked by cathode band; case material meets UL 94V-0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| IF | 1 A - continuous average forward current under specified thermal conditions |
| IFSM | 30 A - non-repetitive peak surge current (8.3 ms half-sine) without damage |
| trr | 150 ns - reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A |
| VF (max) | 1.3 V - forward voltage drop at 1 A and 25°C, directly impacting conduction loss |
| RθJA | 70 °C/W - junction-to-ambient thermal resistance in free-air, defining power derating slope |
| TJ range | –55 to +150 °C - operational junction temperature window for reliable long-term use |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R04 | 1 A, 400 V, 75 ns trr, TO-220AC package, higher VF (1.5 V typ) | Higher thermal mass but larger footprint; suited for heatsinked >5 W designs | Select when lower trr outweighs VF penalty and board space permits TO-220 mounting |
| ON Semi MUR1040 | 1 A, 400 V, 60 ns trr, DO-41 package, VF = 1.25 V max, AEC-Q101 qualified | Superior speed and automotive qualification; tighter VF distribution | Prefer for automotive-grade designs where faster recovery and qualification are mandatory |
Compared with STTH1R04 and MUR1040, FR104G B0G offers balanced speed (150 ns), cost-effective DO-41 packaging, and industrial-grade reliability - making it optimal for cost-sensitive, medium-frequency SMPS where AEC-Q101 is not required.

FAQ
What is the peak repetitive reverse voltage rating of FR104G B0G?
The FR104G B0G has a rated repetitive peak reverse voltage (VRRM) of 400 V. This means it can reliably block up to 400 V in the reverse-biased direction without breakdown under normal operating conditions. The value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version H2104), and applies across the full operating temperature range.
Is FR104G B0G AEC-Q101 qualified?
No, FR104G B0G is not AEC-Q101 qualified. The "B0G" suffix denotes the standard industrial-grade version. AEC-Q101 qualified variants carry the "H" suffix (e.g., FR104GH). The datasheet explicitly states AEC-Q101 qualification is "available" for the FR101G–FR107G family but only for H-suffix parts - FR104G B0G itself is not certified.
What is the forward voltage drop of FR104G B0G at 1 A?
The maximum forward voltage (VF) of FR104G B0G is 1.3 V at IF = 1 A and TJ = 25°C, per the Electrical Specifications table. This value represents worst-case conduction loss under nominal conditions; typical VF is lower. Pulse test conditions (PW = 0.3 ms) ensure measurement reflects real switching behavior, not DC heating effects.
What package type does FR104G B0G use?
FR104G B0G uses the DO-204AL (commonly known as DO-41) axial-leaded package. It features glass-passivated chip construction, pure tin-plated leads compliant with J-STD-002, and a UL 94V-0 rated molding compound. Polarity is indicated by a cathode band on the body.
What is the reverse recovery time (trr) of FR104G B0G?
The reverse recovery time (trr) of FR104G B0G is 150 ns, measured under standardized conditions: IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is critical for minimizing switching losses in high-frequency SMPS designs and is explicitly listed in the Electrical Specifications section of the Taiwan Semiconductor datasheet.
