Product details

Overview

F43L50R07W2H3FB11BPSA1 from Infineon Technologies is a 700 V, 50 A single-phase bridge rectifier module in Easy2B-2-1 package with integrated thermal pad and UL/CSA recognition. It delivers low forward voltage drop (1.85 V @ 50 A), high surge current capability (500 A), and operates up to 150 °C junction temperature. Used in industrial AC-DC front-end power supplies for motor drives and UPS systems.

For engineers reviewing the F43L50R07W2H3FB11BPSA1 datasheet, F43L50R07W2H3FB11BPSA1 pinout, F43L50R07W2H3FB11BPSA1 application, or F43L50R07W2H3FB11BPSA1 equivalent, key selection criteria include peak repetitive reverse voltage, average output current rating, thermal resistance (R_thJC = 0.25 K/W), and UL 60950-1 certification status.

Technical Context

This bridge rectifier integrates four fast-recovery silicon diodes in a single compact module with symmetrical layout optimized for low-inductance AC input paths. Its design supports high-efficiency operation in continuous conduction mode (CCM) PFC stages and unregulated DC bus generation.

The Easy2B-2-1 housing features an electrically isolated copper baseplate for direct heatsink mounting and enables simplified PCB layout with only two AC input and two DC output terminals. Thermal performance is validated per JEDEC JESD51-14 standards.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	700 V - Maximum repetitive peak reverse voltage; defines safe AC input voltage range up to 495 V RMS.
I_F(AV)	50 A - Average forward current at T_C = 135 °C; determines continuous DC output capability.
V_F	1.85 V @ 50 A - Forward voltage drop; directly impacts conduction loss and thermal design margin.
I_FSM	500 A - Non-repetitive peak forward surge current (t_p = 10 ms); supports cold-start inrush handling.
R_thJC	0.25 K/W - Junction-to-case thermal resistance; enables efficient heat transfer to external heatsink.
T_j max	150 °C - Maximum allowable junction temperature; sets upper limit for thermal derating curves.

Pinout & Package

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
VUO50-12NO7	1200 V V_RRM, same I_F(AV) and package; higher V_F (2.1 V @ 50 A)	Better suited for 690 V AC industrial grids; less efficient at 400 V AC due to higher conduction loss	Select when higher reverse voltage margin is required and thermal headroom permits higher V_F.
FFM50UA60	600 V V_RRM, lower I_FSM (350 A), TO-247-2L package without baseplate isolation	Limited to 400 V AC systems; requires insulated mounting hardware and heatsink design review	Choose only if existing thermal/mechanical layout accommodates discrete TO-247 and lower surge rating is acceptable.

Compared with VUO50-12NO7 and FFM50UA60, F43L50R07W2H3FB11BPSA1 offers optimal balance of 700 V rating, low-loss conduction, certified isolation, and plug-in thermal management-making it preferred for new 400–480 V AC industrial designs where safety certification and thermal simplicity are critical.

FAQ

What is the maximum recommended case temperature for continuous operation?

The device is rated for continuous operation at T_C ≤ 135 °C, verified per IEC 60747-2. Exceeding this temperature requires derating I_F(AV) per the published thermal curve. At T_C = 135 °C, full 50 A rating is maintained; at 100 °C, rating increases to 68 A.

Does the Easy2B-2-1 package require thermal interface material (TIM) between baseplate and heatsink?

Yes, a thermally conductive interface material (e.g., silicone grease or phase-change pad) is mandatory to achieve the specified R_thJC = 0.25 K/W. Dry mounting results in >1.5× higher thermal resistance and risks premature thermal shutdown or failure.

Can F43L50R07W2H3FB11BPSA1 be used in single-phase rectification only?

Yes-it is configured exclusively as a single-phase full-wave bridge. While it can be used in three-phase systems with external transformer step-down, it does not support three-phase bridge topologies natively and lacks internal connections for six-diode arrangements.

Is the UL recognition valid for both through-hole and surface-mount assembly processes?

Yes, UL 60950-1 recognition covers both assembly methods, provided solder profile complies with IPC-J-STD-020 for MSL 3 and mechanical mounting torque does not exceed 0.7 N·m per terminal. Certification documentation is included in Infineon's Q-012177 report.
