Product details
Overview
UR3KB100 from Taiwan Semiconductor is a 1000 V, 3 A standard quad bridge rectifier in D3K package, with 90 A surge capability and 150 °C max junction temperature, used in AC/DC front-end stages of switching mode power supplies and LED drivers.
For engineers reviewing the UR3KB100 datasheet, UR3KB100 pinout, UR3KB100 application, or UR3KB100 equivalent, key selection criteria include repetitive peak reverse voltage (1000 V), forward current rating (3.0 A with heatsink), thermal resistance (RθJC = 5.2 °C/W), and UL recognition (E-326243).
Technical Context
The UR3KB100 integrates four silicon diodes in a single-phase bridge configuration, optimized for high-voltage AC input rectification. Its D3K package supports through-hole mounting with matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1A whisker resistance.
Thermal performance is defined by RθJC = 5.2 °C/W and RθJA = 13.7 °C/W, enabling operation up to 150 °C junction temperature. Electrical behavior includes VF ≤ 1.0 V at 1.5 A (25 °C) and IR ≤ 10 µA per diode at rated VR.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU10K | Same 1000 V VRRM, but 10 A IF rating and GBU package (larger footprint, higher thermal mass) | Preferred where higher continuous current or board-level thermal inertia is required | Select GBU10K only if system demands >3 A average current or needs slower thermal response |
| GBU8J | 800 V VRRM, 8 A IF, same D3K-compatible GBU outline but lower voltage rating | Suitable for 115 VAC-only or dual-voltage designs with derated input range | Choose GB8J only when operating below 700 V peak line voltage and higher current headroom is needed |
Compared with GBU10K and GBU8J, the UR3KB100 offers optimal balance of 1000 V rating, D3K footprint compatibility, and 3 A thermal-limited current-making it ideal for space-constrained, universal-input, high-reliability AC/DC converters where precise voltage margin and UL recognition are mandatory.

FAQ
What is the maximum junction temperature specification for UR3KB100?
The UR3KB100 has a maximum junction temperature (TJ) rating of +150 °C, verified per absolute maximum ratings table in the official datasheet. This limit applies under continuous operation with appropriate heatsinking and must be respected to ensure long-term reliability and avoid thermal runaway. Derating curves in the UR3KB100 datasheet show forward current reduction above 125 °C ambient.
Does UR3KB100 meet UL safety certification requirements?
Yes, the UR3KB100 is UL Recognized under File # E-326243, confirming compliance with UL 60747-4 for semiconductor devices. This certification covers dielectric strength, flammability (UL 94V-0), and construction integrity-critical for end-equipment safety approvals in North America and globally harmonized markets.
What is the forward voltage drop of UR3KB100 at rated current?
The UR3KB100 exhibits a maximum forward voltage drop (VF) of 1.0 V per diode at IF = 1.5 A and TJ = 25 °C, as specified in the electrical characteristics table. At full 3.0 A load with heatsink, VF increases due to self-heating but remains within design margins for typical 100–200 kHz SMPS topologies.
Can UR3KB100 replace UR3KB80 in an existing design?
Yes, UR3KB100 is a direct voltage-upgraded variant of UR3KB80, sharing identical D3K package, pinout, thermal specs, and mechanical dimensions. Substituting UR3KB100 provides increased reverse voltage margin (1000 V vs. 800 V) without layout or thermal redesign-ideal for strengthening surge immunity in legacy 230 VAC systems.
What is the I²t rating for UR3KB100 and why does it matter?
The UR3KB100 has an I²t rating of 33.61 A²s for fusing under 8.3 ms single half-sine surge conditions. This value quantifies its ability to absorb short-duration energy without metallization failure, directly informing fuse selection and inrush protection design-especially critical in applications with large input capacitors or frequent hot-plug events.
