Taiwan Semiconductor Corporation YBS3007G

Overview

YBS3007G from Taiwan Semiconductor is a 1000V, 3A standard quad bridge rectifier with glass-passivated junctions, 110A surge capability, and YBS surface-mount package - used in high-reliability AC/DC front-ends for industrial SMPS and lighting ballasts.

For engineers reviewing the YBS3007G datasheet, YBS3007G pinout, YBS3007G application, or YBS3007G equivalent, key selection factors include peak reverse voltage (1000V), forward current rating (3A), thermal resistance (R_θJL = 22°C/W), and UL recognition (E-326854) for safety-critical power conversion designs.

Technical Context

The YBS3007G integrates four diodes in a single-phase full-wave bridge configuration with common-cathode and common-anode terminals. Its glass-passivated chip junction ensures stable reverse leakage (<5 µA at 25°C, <100 µA at 125°C) and robust surge handling (IFSM = 110A at 8.3ms).

Thermal performance is defined for PCB mounting on a 16mm × 16mm copper pad: R_θJA = 61°C/W, R_θJC = 9°C/W, and R_θJL = 22°C/W - enabling reliable operation up to T_J = 150°C in compact, convection-cooled layouts.

FAQ

What is the maximum repetitive peak reverse voltage rating for YBS3007G?

The YBS3007G has a maximum repetitive peak reverse voltage (V_RRM) of 1000 V, verified per Taiwan Semiconductor's D2103 datasheet revision. This rating allows safe operation with 700V_RMS AC inputs and provides margin against line surges in industrial environments. The YBS3007G is the highest-voltage variant in the YBS3004G–YBS3007G family, directly replacing lower-voltage versions where increased transient immunity is required.

Does YBS3007G require pre-reflow baking before SMT assembly?

No, YBS3007G does not require pre-reflow baking because it is rated at moisture sensitivity level (MSL) 1 per J-STD-020. This means the device can be stored indefinitely at ≤30°C/60% RH and processed using standard reflow profiles without risk of popcorning. The YBS3007G's molded plastic package and matte tin-plated leads are fully compatible with lead-free reflow processes.

Is YBS3007G UL recognized, and what is its file number?

Yes, YBS3007G is UL Recognized under file number E-326854. This certification applies to the entire YBS3004G–YBS3007G series and confirms compliance with UL 60747-4 for semiconductor devices. The UL recognition covers construction, flammability (UL 94V-0), and electrical safety - reducing qualification effort for end-equipment meeting UL/CSA standards.

What is the forward voltage drop of YBS3007G at full rated current?

At I_F = 3.0 A and T_J = 25°C, the YBS3007G exhibits a typical forward voltage (V_F) of 0.93 V, with a maximum of 1.10 V per diode. At elevated junction temperature (125°C), V_F drops to 0.82 V (typ) / 1.00 V (max), reflecting silicon's negative temperature coefficient - a key factor in thermal stability during sustained load conditions.

Can YBS3007G replace YBS3004G or YBS3006G in an existing design?

YBS3007G is a direct drop-in replacement for YBS3004G (400V) and YBS3006G (800V) in the same YBS package - identical pinout, footprint, and thermal characteristics. However, its higher V_RRM does not degrade performance; it only increases voltage margin. Designers should verify that the higher breakdown rating does not affect snubber or clamping network tuning, though no PCB changes are required for mechanical or electrical integration of YBS3007G.
