Product details

Overview

FR152G R0G from Taiwan Semiconductor is a 1.5A, 100V 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 capability - used in switching-mode power supplies for efficient AC/DC conversion.

For engineers reviewing the FR152G R0G datasheet, FR152G R0G pinout, FR152G R0G application, or FR152G R0G equivalent, key selection criteria include V_RRM = 100 V, I_F = 1.5 A, t_rr = 150 ns, thermal resistance R_θJA = 60 °C/W, and AEC-Q101 qualification availability (R0G suffix indicates standard grade).

Technical Context

This single-die fast recovery rectifier uses glass-passivated junction technology to achieve low forward voltage and high surge robustness. Its 150 ns reverse recovery time enables operation in high-frequency switching converters up to several hundred kHz without excessive switching loss.

The DO-204AC (DO-15) package supports through-hole mounting with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Polarity is marked by cathode band; maximum junction temperature is 150 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - maximum repetitive reverse voltage; defines safe blocking capability in DC-DC flyback or boost stages
I_F	1.5 A - average forward current rating; determines continuous conduction capability at T_A ≤ 75 °C
t_rr	150 ns - reverse recovery time; limits switching frequency and EMI in SMPS designs
V_F (max)	1.3 V @ 1.5 A, 25 °C - forward voltage drop; directly impacts conduction loss and thermal design
I_FSM	50 A - non-repetitive surge current (8.3 ms half-sine); ensures reliability during power-up or fault transients
R_θJA	60 °C/W - junction-to-ambient thermal resistance; informs heatsinking requirements for ambient-limited operation

Pinout & Package

DO-204AC (DO-15) axial-leaded package with cathode indicated by band; no internal pins - two terminals only: anode and cathode.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential side of circuit; must withstand reverse voltage when cathode is biased higher
Cathode	Forward current exit point / polarity indicator	Marked by band; connects to output rail or switching node; carries full load current in forward conduction

Equivalent & Alternatives

The following parts are listed as comparable options for similar fast recovery rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1L06U	V_RRM = 600 V, t_rr = 65 ns, I_F = 1 A, SOD-123FL package	Higher voltage rating but lower current; surface-mount only	Select when board space is constrained and V_RRM > 100 V is required; not drop-in due to package and current mismatch
ON Semi MUR120	V_RRM = 200 V, t_rr = 75 ns, I_F = 1 A, DO-41 package	Faster recovery but lower current and higher V_RRM; same axial form factor	Prefer for higher-frequency designs where 1 A suffices; requires layout verification due to different marking and lead pitch

Compared with STTH1L06U and MUR120, FR152G R0G offers optimal balance of 100 V rating, 1.5 A current, and DO-15 through-hole compatibility for cost-sensitive, medium-power industrial supplies - neither alternative matches its exact I_F/V_RRM/package combination.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for FR152G R0G?

The FR152G R0G has a V_RRM of 100 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version I2105). This rating defines the highest reverse voltage the device can block repeatedly without breakdown under normal operating conditions and is strictly validated per JEDEC test methods.

Is FR152G R0G RoHS and halogen-free compliant?

Yes, FR152G R0G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. The "G" suffix denotes green compound molding, and the device meets UL 94V-0 flammability requirements.

What is the reverse recovery time (t_rr) of FR152G R0G, and under what test conditions?

The FR152G R0G has a reverse recovery time of 150 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A, as specified in the ELECTRICAL SPECIFICATIONS table. This value applies across the full operating temperature range and is critical for minimizing switching loss in high-frequency converters.

Does FR152G R0G have AEC-Q101 qualification?

No, FR152G R0G is not AEC-Q101 qualified. The "R0G" suffix indicates the standard-grade version. AEC-Q101 qualified variants are marked with "H" (e.g., FR152GH), as noted in the ORDERING INFORMATION section of the datasheet.

What is the thermal resistance (R_θJA) of FR152G R0G, and how does it affect PCB layout?

The junction-to-ambient thermal resistance of FR152G R0G is 60 °C/W, measured on a standard JEDEC 2S2P test board. This value assumes minimal copper area; adding ≥1 cm² of 2-oz copper pour on both sides reduces effective R_θJA by ~20–30%, directly lowering steady-state junction temperature under 1.5 A load.
