Product details

Overview

YBS3005G from Taiwan Semiconductor is a 3A, 600V repetitive peak reverse voltage (V_RRM) standard quad bridge rectifier in YBS package, featuring glass-passivated junctions, 110A surge capability (t = 8.3ms), and UL recognition (E-326854), used in AC/DC front-end stages of switching mode power supplies.

For engineers reviewing the YBS3005G datasheet, YBS3005G pinout, YBS3005G application, or YBS3005G equivalent, key selection factors include V_RRM = 600V, I_F = 3A continuous, thermal resistance R_θJL = 22°C/W, and compliance with J-STD-020 level 1 moisture sensitivity and RoHS/halogen-free requirements.

Technical Context

The YBS3005G integrates four silicon diodes in a single-phase full-wave bridge configuration with common-cathode and common-anode terminals externally accessible. Its glass-passivated junction ensures stable reverse leakage (<5 µA at 25°C, <100 µA at 125°C) and high reliability under repeated surge stress.

Thermal performance is characterized by R_θJC = 9°C/W and R_θJA = 61°C/W on a 16mm × 16mm Cu pad PCB, supporting operation up to T_J = 150°C. Forward voltage is specified at 0.93–1.10 V (I_F = 3.0A, T_J = 25°C), enabling efficient conduction in compact SMPS designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Maximum non-repetitive reverse voltage the device withstands without breakdown; defines usable input AC range in bridge rectification.
I_F	3 A - Continuous average forward current per device; determines sustained power handling in DC output stage.
I_FSM	110 A (8.3 ms) - Peak non-repetitive surge current; supports inrush current tolerance during cold-start of power supplies.
V_F	0.93–1.10 V @ 3.0A, 25°C - Forward voltage drop per diode; directly impacts conduction loss and thermal design margin.
R_θJL	22 °C/W - Junction-to-lead thermal resistance; enables direct heatsinking via PCB copper pour or external clip.
T_J max	150 °C - Maximum allowable junction temperature; sets upper limit for ambient + power-loss-derived temperature rise.
I_R	<5 µA @ 25°C - Reverse leakage current per diode; critical for low-power standby efficiency and voltage hold-up stability.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
GBU6K (ON Semiconductor)	Same I_F = 3A, V_RRM = 600V, but GBU package (larger footprint, higher R_θJA = 70°C/W)	Requires PCB layout revision due to different outline and lead spacing; less suitable for ultra-compact adapters	Select when legacy GBU footprint compatibility is required and thermal margin allows higher R_θJA
MB10F (Diotec)	I_F = 1.0A only; V_RRM = 1000V; smaller DO-204AL package; no UL recognition	Not suitable for 3A continuous loads; requires parallel devices or derating; lacks safety certification for end-product approval	Consider only for low-power, cost-sensitive, non-certified applications where 600V rating suffices and space is constrained

Compared with GBU6K and MB10F, the YBS3005G offers optimal balance of certified safety (UL), compact YBS footprint, industry-standard 3A/600V rating, and superior thermal resistance (R_θJL = 22°C/W), making it preferred for volume-manufactured, certified AC/DC converters.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for YBS3005G?

The YBS3005G has a V_RRM of 600 V, as confirmed in the Absolute Maximum Ratings table across all versions of the YBS3004G–YBS3007G family. This value is fixed per part number and defines the highest sinusoidal reverse voltage the device can block repeatedly without breakdown under normal operating conditions.

Does YBS3005G require baking before reflow soldering?

No, YBS3005G does not require baking prior to reflow. It is rated J-STD-020 Level 1 for moisture sensitivity, meaning it has unlimited floor life and may be placed directly onto PCBs and processed through standard lead-free reflow profiles without preconditioning or dry-pack handling.

Is YBS3005G UL recognized, and what is its file number?

Yes, YBS3005G is UL Recognized under File # E-326854. This certification applies to the entire YBS3004G–YBS3007G series and validates compliance with UL 60950-1/62368-1 for use in end-product safety evaluations.

What is the forward voltage (V_F) of YBS3005G at 3.0A and 25°C?

At I_F = 3.0A and T_J = 25°C, the YBS3005G exhibits a typical forward voltage of 0.93 V and a maximum of 1.10 V per diode, as specified in the Electrical Specifications table. These values are measured under pulsed conditions (PW = 0.3ms) to avoid self-heating effects.

Can YBS3005G replace YBS3004G or YBS3006G in an existing design?

No-YBS3005G is not a drop-in replacement for YBS3004G (400V) or YBS3006G (800V). While pinout and package are identical, the V_RRM rating differs per part number. Substitution requires verification that the new V_RRM meets or exceeds the original design's worst-case reverse voltage stress.
