Product details

Overview

FR202G-T from Taiwan Semiconductor is a 2A, 100V fast recovery rectifier diode in DO-204AC (DO-15) package, featuring 150 ns reverse recovery time, 1.3 V forward voltage at 2 A, and 55 A surge current capability; used in switching-mode power supplies and DC-DC converters.

For engineers reviewing the FR202G-T datasheet, FR202G-T pinout, FR202G-T application, or FR202G-T equivalent, key selection criteria include V_RRM = 100 V, I_F = 2 A, t_rr = 150 ns, V_F ≤ 1.3 V, and thermal resistance R_θJA = 70 °C/W under standard mounting conditions.

Technical Context

This device is a single-die, glass-passivated silicon junction rectifier optimized for high-efficiency switching applications. Its fast recovery (t_rr = 150 ns) minimizes switching losses in high-frequency converters, while low forward voltage (V_F ≤ 1.3 V at 2 A) reduces conduction loss.

The DO-204AC (DO-15) package supports through-hole mounting with pure tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1A whisker resistance. Maximum junction temperature is rated at 150 °C, enabling reliable operation in industrial ambient environments.

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	2 A - average forward current rating; determines continuous power handling in rectification paths
t_rr	150 ns - reverse recovery time; enables stable operation up to ~500 kHz switching frequencies
V_F	≤1.3 V @ 2 A, 25°C - forward voltage drop; directly impacts conduction loss and thermal rise in high-duty-cycle designs
I_FSM	55 A - non-repetitive surge current; withstands inrush and transient overloads without failure
R_θJA	70 °C/W - junction-to-ambient thermal resistance; guides heatsinking requirements on standard PCB copper

Pinout & Package

DO-204AC (DO-15) package: axial-leaded, glass-passivated, cathode indicated by band; lead finish is pure tin, solderable per J-STD-002; weight ≈ 0.400 g.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry	Connected to lower-potential side (e.g., transformer secondary center-tap or switch node)
Cathode	Forward current exit / reverse blocking terminal	Marked with band; connects to output filter capacitor positive or load return path

Key Features

Feature	Design Value

Applications

DC-DC Converter Output Rectification	Switching Mode Inverter Input Stage
Use Scenario: Secondary-side rectification in isolated 24–48 V input DC-DC converters delivering 5–12 V at up to 2 A. IC Role / Device Role / Timing Role: Fast recovery rectifier conducting during transformer demagnetization phase; blocks reverse voltage during switch-on period. Use Value: 150 ns t_rr prevents reverse recovery tail current from overlapping with high-side MOSFET turn-on, reducing cross-conduction loss.	Use Scenario: Input AC rectification in 100–240 VAC-fed inverters powering motor drives or UPS systems. IC Role / Device Role / Timing Role: Bridge leg diode providing unidirectional current path; handles 55 A surge during line transients or startup. Use Value: 100 V V_RRM and 55 A I_FSM ensure robustness against 1.5× nominal line surges without derating.
Industrial Power Supply Front-End	LED Driver Bulk Rectification
Use Scenario: Input rectification in DIN-rail mounted 24 V/48 V industrial PSUs operating continuously at 40–70°C ambient. IC Role / Device Role / Timing Role: Single-phase bridge diode handling 2 A average current; operates at TJ ≤ 125°C under natural convection. Use Value: 150 °C max junction temperature and 70 °C/W R_θJA allow full-rated current without forced air cooling.	Use Scenario: Bulk rectification stage in constant-current LED drivers for street lighting (100–200 W). IC Role / Device Role / Timing Role: Converts rectified AC to pulsating DC prior to buck regulation; must survive 100 kHz PWM-induced ripple. Use Value: Low capacitance (C_J = 10 pF) minimizes high-frequency coupling into control circuitry, improving EMI margin.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R01	V_RRM = 100 V, t_rr = 120 ns, V_F = 1.15 V @ 2 A, DO-41 package	Lower V_F and faster t_rr, but smaller package limits thermal mass and surge handling	Preferred where board space is constrained and peak surge < 40 A
1N5622	V_RRM = 100 V, t_rr = 200 ns, V_F = 1.3 V @ 2 A, DO-204AC package	Slower recovery increases switching loss in >200 kHz designs; identical footprint and solder process	Drop-in replacement if t_rr margin allows; no PCB change required

Compared with STTH2R01 and 1N5622, FR202G-T offers balanced trade-offs: identical DO-204AC footprint and surge rating (55 A) as 1N5622, yet faster recovery than 1N5622 and better thermal robustness than STTH2R01's DO-41 package.

FAQ

What is the maximum junction temperature rating for FR202G-T?

The FR202G-T has a maximum junction temperature (T_J) rating of +150 °C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet Version B2105. This allows continuous operation at full 2 A current in ambient temperatures up to 80 °C when mounted on standard FR-4 PCB with 1-inch² copper pour. Exceeding this limit risks permanent degradation of the glass-passivated junction.

Does FR202G-T have a specified reverse recovery time, and how is it measured?

Yes, FR202G-T specifies a reverse recovery time (t_rr) of 150 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A per the electrical specifications table. This value is confirmed across the FR201G-T to FR204G-T group and reflects performance at 25°C junction temperature using standardized half-sine test waveforms.

Is FR202G-T RoHS and halogen-free compliant?

Yes, FR202G-T is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. The molding compound meets UL 94V-0 flammability rating, and terminals are pure tin plated-fully compatible with lead-free reflow and wave soldering processes per J-STD-002.

What is the forward voltage drop of FR202G-T at rated current?

The forward voltage (V_F) of FR202G-T is guaranteed ≤1.3 V at I_F = 2 A and T_J = 25°C, per the ELECTRICAL SPECIFICATIONS table. At elevated junction temperatures (e.g., 125°C), V_F decreases slightly due to negative temperature coefficient of silicon PN junctions, remaining within design-safe margins for thermal calculation.

Can FR202G-T be used as a direct replacement for FR201G-T in an existing design?

No-FR202G-T is not a direct replacement for FR201G-T due to differing V_RRM ratings: FR201G-T is rated for 50 V, while FR202G-T is rated for 100 V. Although both share identical package, pinout, and thermal specs, substituting FR202G-T in a 50 V design may increase leakage or reduce efficiency without benefit; use only where 100 V blocking is required.
