Diodes Incorporated KBJL1506-TU

Overview

KBJL1506-TU from Diodes Incorporated is a 15A standard recovery bridge rectifier in KBJL package, rated for 600V repetitive peak reverse voltage (VRRM), with maximum forward voltage of 1.0V at 7.5A and leakage current ≤10µA at 25°C. It features glass-passivated die construction, RoHS-compliant matte tin-plated leads, and is optimized for AC/DC power conversion in consumer power supplies.

For engineers reviewing the KBJL1506-TU datasheet, KBJL1506-TU pinout, KBJL1506-TU application, or KBJL1506-TU equivalent, key selection criteria include VRRM rating, thermal resistance (RθJA = 23°C/W without heatsink), surge capability (220A @ 8.3ms), junction capacitance (55pF), and compliance with AEC-Q200-ready manufacturing facilities.

Technical Context

This single-phase full-wave bridge rectifier integrates four silicon diodes in a monolithic molded plastic (UL 94V-0) package with standardized KBJL mechanical outline. Its glass-passivated junction ensures stable reverse characteristics across -55°C to +150°C operating range.

The device delivers 15A average forward current with heatsink at TC = +130°C, derating to 2.8A without heatsink under same conditions. Thermal resistance junction-to-ambient is 23°C/W (no heatsink) and 4°C/W (with 35mm × 35mm × 1.7mm Cu heatsink), enabling predictable thermal design in compact power supplies.

FAQ

What is the maximum case temperature for continuous operation?

KBJL1506-TU supports continuous operation up to +130°C case temperature when mounted on an adequate heatsink, delivering its full 15A average forward current. Without heatsink, derating applies: at +130°C case, it sustains only 2.8A average current per the datasheet's derating curve.

Is KBJL1506-TU suitable for automotive applications?

KBJL1506-TU is manufactured in IATF 16949-certified facilities and supports PPAP documentation, but it is not AEC-Q200 qualified out-of-the-box. For automotive use, Diodes recommends contacting their applications team to confirm qualification status and obtain change-controlled versions meeting specific vehicle-grade requirements.

How does thermal resistance change with heatsink mounting?

Without heatsink, RθJA is 23°C/W; with a 35mm × 35mm × 1.7mm copper heatsink, RθJA drops to 4°C/W. RθJC is 1°C/W and RθJL is 3°C/W under that condition, enabling precise junction temperature calculation using TJ = TA + (Pd × RθJA) or TJ = TC + (Pd × RθJC).

What marking code identifies KBJL1506-TU on the device body?

The device is marked "Green KBJL1506 YWW", where "Green" indicates halogen/antimony-free compliance, "KBJL1506" is the product type code, and "YWW" denotes date code (e.g., "523" = year 2025, week 23). The marking appears on the top surface of the molded KBJL package.
