Product details
Overview
UABF1510 from Diodes Incorporated is a 1.5A, 1000V peak repetitive reverse voltage (VRRM) surface-mount fast glass passivated bridge rectifier in SOPA-4 (Type B) package, featuring 1.3V max forward voltage at 1.5A, 160ns reverse recovery time, and 5μA max reverse leakage at 25°C - used for AC–DC full-wave rectification in LED lighting power supplies and compact adapters.
For engineers reviewing the UABF1510 datasheet, UABF1510 pinout, UABF1510 application, or UABF1510 equivalent, this device supports high-efficiency SMT designs requiring low-profile packaging, ultrafast recovery, and RoHS-compliant lead-free termination with verified thermal resistance (RθJA = 80°C/W per element).
Technical Context
The UABF1510 integrates four fast-switching diodes in a single-phase bridge configuration with glass passivated junctions, enabling reliable operation up to 150°C junction temperature and supporting 50A non-repetitive surge current (8.3ms half-sine). Its 17pF typical capacitance per element minimizes high-frequency switching noise in SMPS input stages.
Designed for space-constrained applications, it uses SOPA-4 (Type B) packaging with 3.8mm pitch, matte tin-plated terminals, and J-STD-020 Level 1 moisture sensitivity - optimized for reflow soldering without derating under standard PCB thermal management (1.3mm² copper pad on aluminum substrate).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands peak reverse voltage in universal-input (85–265VAC) rectifier circuits without breakdown. |
| IO | 1.5 A average - Delivers continuous DC output current for sub-20W LED drivers and wall adapters. |
| VFM | 1.3 V @ 1.5A - Reduces conduction loss and thermal stress compared to standard silicon bridges (e.g., 1.8V typical). |
| tRR | 160 ns - Limits switching losses and EMI generation during high-frequency AC line rectification. |
| RθJA | 80 °C/W per element - Enables thermal design with minimal copper area on FR-4 or aluminum PCBs. |
| IR | 5 μA @ 25°C - Ensures low standby power loss in battery charger no-load conditions. |
| CT | 17 pF @ 1MHz - Minimizes capacitive coupling and dv/dt-induced false triggering in adjacent control circuitry. |
Pinout & Package
SOPA-4 (Type B) package: 4-pin surface-mount outline with 3.8mm pin pitch, 5.05mm × 6.4mm body, 1.2mm max height, and molded plastic UL 94V-0 housing. Terminals are matte tin-plated for lead-free reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (+) | Anode of upper-left diode / Positive DC output | Connects to load positive rail; marked with "+" symbol on top silkscreen. |
| 2 (AC1) | AC input terminal 1 / Bridge input leg 1 | Accepts one phase of AC input; tied internally to cathode of lower-left diode. |
| 3 (AC2) | AC input terminal 2 / Bridge input leg 2 | Accepts second AC phase; tied internally to cathode of lower-right diode. |
| 4 (–) | Cathode of upper-right diode / Negative DC output | Connects to load ground/negative rail; marked with "–" symbol on top silkscreen. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die construction | Prevents surface contamination and moisture ingress, ensuring long-term reliability in humid environments (e.g., outdoor LED fixtures). |
| Ultrafast 160ns recovery time | Reduces reverse recovery charge (Qrr) and associated switching losses in 50–100kHz SMPS front-ends. |
| Low 1.3V forward drop at rated current | Lowers power dissipation by ~0.75W vs. conventional bridges, easing thermal design in sealed enclosures. |
| SOPA-4 (Type B) low-profile package | Enables PCB height clearance ≤1.2mm - critical for slim LED drivers and USB-C PD adapters. |
| RoHS 3 & halogen/antimony-free | Meets IEC 61215 and ENERGY STAR requirements for eco-design compliance in consumer electronics. |
Applications
| LED Lighting Power Supply | USB Wall Adapter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU4K (ON Semiconductor) | Higher VRRM (800V), slower tRR (250ns), larger GBU package (10.5mm × 14.5mm) | Requires PCB real estate increase; unsuitable for height-constrained designs | Choose only if higher surge rating (100A IFSM) outweighs size penalty. |
| DF08MA (Vishay) | Same SOPA-4 footprint, but VRRM = 800V and VFM = 1.45V @ 1.5A | Lower voltage margin limits use in 277VAC industrial lighting | Select when cost sensitivity dominates and input voltage stays ≤240VAC. |
Compared with GBU4K and DF08MA, the UABF1510 uniquely balances 1000V rating, 160ns speed, and SOPA-4 miniaturization - making it optimal for next-gen LED drivers where board space, efficiency, and universal input range are jointly constrained.

FAQ
What is the maximum operating temperature for UABF1510?
The UABF1510 has an operating junction temperature range of –55°C to +150°C. At 100°C case temperature (TC), its average rectified output current remains rated at 1.5A. Derating begins above TC = 100°C per Figure 1 in DS39876 Rev. 3–2.
Is UABF1510 compatible with lead-free reflow profiles?
Yes - UABF1510 features matte tin-plated terminals qualified to MIL-STD-202, Method 208, and supports JEDEC J-STD-020 Class 1 moisture sensitivity. It is fully compatible with standard Pb-free reflow profiles peaking at 260°C.
How does UABF1510's 160ns recovery time improve system efficiency?
The 160ns reverse recovery time reduces stored charge (Qrr) and associated switching losses during AC zero-crossings, especially in 50–100kHz SMPS front-ends. This directly lowers heat generation and improves full-load efficiency by up to 0.8% versus 250ns bridges.
Can UABF1510 replace KBU4B in existing designs?
No - KBU4B uses a through-hole KBU package (22.5mm × 18.5mm), while UABF1510 is surface-mount SOPA-4 (5.05mm × 6.4mm). Direct replacement requires PCB redesign. Electrical substitution is viable only after verifying layout thermal relief and surge margin (KBU4B has 100A IFSM vs. UABF1510's 50A).
