Product details
Overview
KBJL1510-TU from Diodes Incorporated is a 15A standard recovery bridge rectifier with 1000V peak repetitive reverse voltage (VRRM), 1.0V max forward voltage at 7.5A, and 10µA max reverse leakage current at 25°C. It features glass passivated die construction, UL recognition (E95060), and is optimized for high-surge AC/DC power supplies in consumer electronics.
For engineers reviewing the KBJL1510-TU datasheet, KBJL1510-TU pinout, KBJL1510-TU application, or KBJL1510-TU equivalent, key selection criteria include VRRM rating for input voltage margin, thermal resistance (RθJC = 1°C/W with heatsink), surge capability (440A @ 1.0ms), and RoHS-compliant green packaging for TV, PC, and gaming power supply designs.
Technical Context
This single-phase full-wave bridge rectifier integrates four silicon diodes in a molded KBJL package with matte tin-plated leads. Its standard recovery characteristic (trr not specified, typical for standard recovery bridges) supports line-frequency (50/60Hz) rectification without requiring snubbers in most applications.
Thermal performance is defined by dual RθJC values: 1°C/W with a 35mm × 35mm × 1.7mm Cu heatsink and 5°C/W without heatsink. Junction temperature range spans –55°C to +150°C, enabling operation in thermally demanding environments such as enclosed power adapters and game console SMPS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands peak reverse voltage up to 1000V, suitable for 700VAC mains-derived inputs with safety margin. |
| IF(AV) | 15 A - Average rectified output current with heatsink at TC = +130°C; derates to 2.8A without heatsink. |
| VF Max | 1.0 V @ 7.5A - Low conduction loss improves efficiency and reduces heat generation in high-current DC bus paths. |
| IR Max | 10 µA @ 25°C - Minimal reverse leakage ensures stable blocking under standby conditions. |
| IFSM (1.0ms) | 440 A - Handles high-energy inrush surges during cold-start of switched-mode power supplies. |
| RθJC | 1 °C/W - Thermal resistance junction-to-case with specified copper heatsink enables predictable thermal design. |
| CT | 55 pF @ 1MHz, 4V - Low junction capacitance minimizes switching noise coupling in EMI-sensitive power stages. |
Pinout & Package
Package: KBJL - Molded plastic, UL 94V-0 rated, 2.4g weight, with matte tin-plated leads solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ~AC1 | AC Input Terminal 1 | One leg of AC input; connects to transformer secondary or bridge input node. |
| ~AC2 | AC Input Terminal 2 | Second leg of AC input; completes full-wave rectification path with ~AC1. |
| +DC | Positive DC Output | Anode common of two series diodes; delivers rectified positive rail to filter capacitor. |
| –DC | Negative DC Output / Ground Reference | Cathode common of two series diodes; serves as return path and system ground reference. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU15K-E3/51 | Same KBU/KBJL-compatible package; 1000V VRRM, 15A IF(AV), but VF = 1.1V @ 7.5A (0.1V higher). | Slightly higher conduction loss may increase thermal load in compact, heatsink-limited designs. | Select when GBU-series sourcing or legacy BOM alignment is required; verify thermal margin. |
| KBPC1510 | Standard recovery bridge, same VRRM/IF ratings, but larger KBPC package (35.5mm × 20.5mm vs. KBJL's 25.3mm × 10.6mm). | Requires more PCB area; not drop-in compatible due to different lead pitch and body dimensions. | Choose only if existing layout accommodates KBPC footprint or thermal testing confirms equivalency. |
Compared with GBU15K-E3/51 and KBPC1510, KBJL1510-TU offers lower forward voltage and a smaller, surface-mount-friendly KBJL outline-critical for space-constrained consumer power supplies where thermal and footprint efficiency are prioritized.

FAQ
What is the maximum junction temperature for continuous operation?
The KBJL1510-TU has an operating junction temperature range of –55°C to +150°C. For continuous operation at rated 15A average current, the case temperature must be maintained at ≤+130°C with an appropriate heatsink, as specified in the derating curve (Figure 1). Exceeding TJ = +150°C risks permanent parametric shift or failure.
Is KBJL1510-TU suitable for use without a heatsink?
Yes, but only at reduced current: the datasheet specifies 2.8A IF(AV) without heatsink at TC = +130°C. In practice, this requires careful PCB copper area design (≥35mm² thermal pad) and low ambient temperature. For >5A loads, a heatsink is strongly recommended to maintain reliability and avoid thermal runaway.
Does KBJL1510-TU meet automotive qualification standards?
No-the KBJL1510-TU is not AEC-Q101 qualified. While it operates from –55°C to +150°C, Diodes explicitly states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing. This part is intended for commercial/industrial consumer power applications, not automotive ECUs or infotainment systems.
How does the KBJL package differ from KBPC or GBU packages?
The KBJL package is dimensionally smaller than KBPC (25.3mm × 10.6mm vs. 35.5mm × 20.5mm) and has a tighter lead pitch (e = 7.3–7.7mm vs. GBU's 7.8mm). It uses a more compact body height and optimized lead frame for automated insertion and reflow compatibility, making it preferred for space-constrained consumer power boards where KBPC/GBU footprints are prohibitive.
