Taiwan Semiconductor Corporation FR153G R0G

Overview

FR153G R0G from Taiwan Semiconductor is a 1.5A, 200V fast recovery rectifier diode in DO-204AC (DO-15) package, featuring 150 ns reverse recovery time, 1.3 V max forward voltage at 1.5 A, and 50 A surge current capability - used in switching-mode DC/DC converters requiring efficient unidirectional conduction.

For engineers reviewing the FR153G R0G datasheet, FR153G R0G pinout, FR153G R0G application, or FR153G R0G equivalent, key selection criteria include V_RRM = 200 V, I_F = 1.5 A, t_rr = 150 ns, thermal resistance R_θJA = 60 °C/W, and DO-15 mechanical compatibility with automated through-hole assembly.

Technical Context

This single-die, glass-passivated fast recovery rectifier operates with junction temperature range –55°C to +150°C and supports repetitive peak reverse voltages up to 200 V. Its low forward voltage drop (≤1.3 V @ 1.5 A, 25°C) and tight reverse leakage (≤5 µA @ 25°C, rated V_R) enable high-efficiency power conversion in compact designs.

The device exhibits 20 pF junction capacitance at 1 MHz / 4 V and achieves fast switching via controlled carrier lifetime, delivering 150 ns reverse recovery time under standardized IF = 0.5 A / IR = 1.0 A / I_rr = 0.25 A test conditions - critical for minimizing switching losses in 50–500 kHz SMPS topologies.

FAQ

What is the maximum junction temperature rating for FR153G R0G?

The FR153G R0G has a maximum junction temperature (T_JMAX) of +150°C, with operational range from –55°C to +150°C. This rating allows reliable operation in enclosed industrial enclosures or near heat-generating components when derated per the forward current derating curve. Thermal design must account for R_θJA = 60 °C/W to avoid exceeding T_JMAX under full load.

Does FR153G R0G meet automotive qualification standards?

No, FR153G R0G is not AEC-Q101 qualified. The "R0G" suffix denotes standard industrial grade. AEC-Q101 qualification is available only on the "H" variant (e.g., FR153GH). For automotive applications requiring stress-tested reliability, FR153GH must be specified - FR153G R0G is intended for industrial, consumer, and commercial power supplies.

What is the reverse recovery time specification for FR153G R0G?

The reverse recovery time (t_rr) for FR153G R0G is 150 ns, measured under standardized conditions: I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A. This value is confirmed in the official Taiwan Semiconductor datasheet Version I2105 and applies specifically to the FR153G variant - it is not interpolated from adjacent family members.

Is FR153G R0G RoHS and halogen-free compliant?

Yes, FR153G R0G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants, and the pure tin-plated leads satisfy J-STD-002 solderability requirements. These attributes are explicitly stated in the "Features" section of the Taiwan Semiconductor FR151G–FR157G datasheet.

What does the "R0G" suffix mean in FR153G R0G?

The "R0G" suffix in FR153G R0G indicates tape-and-reel packaging (3,500 pcs/reel) with green compound and standard industrial qualification. It is distinct from "H" (AEC-Q101), "A0G" (ammo box), and "GH" (AEC-Q101 + tape-and-reel). No functional or electrical differences exist between FR153G R0G and bare FR153G - only packaging and marking variants.
