Product details
Overview
KBJ15L06-TU from Diodes Incorporated is a 15A, 600V glass-passivated bridge rectifier in KBJ package, featuring low forward voltage (0.9 V @ 7.5 A), 10 µA max reverse leakage at 25°C, and 2500 VRMS dielectric strength - deployed in AC/DC power supplies for industrial motor drives and HVAC control systems.
For engineers reviewing the KBJ15L06-TU datasheet, KBJ15L06-TU pinout, KBJ15L06-TU application, or KBJ15L06-TU equivalent, key selection criteria include thermal resistance (1.5 °C/W junction-to-case with heatsink), surge rating (200 A IFSM), and RoHS-compliant matte tin plating suitable for automated PCB assembly.
Technical Context
This single-phase full-wave bridge rectifier integrates four silicon diodes in a monolithic plastic-molded KBJ package with polarity marking on body. Its glass-passivated junction ensures stable reverse characteristics across -55°C to +150°C operating range and supports high-reliability operation under repetitive 60 Hz line surges.
Designed for PCB mounting without orientation constraints, it delivers 15 A average forward current at TC = +125°C with heatsink, derating to 3.9 A at same temperature without heatsink - validated by JEDEC-standard thermal metrics (RθJC = 1.5 °C/W) and UL 94V-0 flammability compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands peak reverse line voltage in 400 VAC mains applications without breakdown |
| IF(AV) | 15 A @ TC = +125°C with heatsink - Sustains continuous output in high-power SMPS front-ends |
| VF Max | 0.90 V @ 7.5 A, 25°C - Reduces conduction loss and thermal stress vs. standard 1.1 V bridges |
| IR Max | 10 µA @ 600 V, 25°C - Minimizes standby power loss in energy-sensitive designs |
| I²t Rating | 166 A²s (8.3 ms) - Survives 200 A non-repetitive surge per ANSI/UL standards |
| RθJC | 1.5 °C/W (with heatsink) - Enables compact thermal design using 200×200×5 mm Al plate |
| Dielectric Strength | 2500 VRMS - Meets reinforced insulation requirements for Class I equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU15J-E3/51 | Same 600 V VRRM, 15 A IF(AV), but VF = 1.05 V @ 7.5 A; RθJC = 2.0 °C/W | Higher conduction loss and thermal resistance reduce margin in compact heatsink designs | Prefer when legacy footprint compatibility with GBU series is required over VF optimization |
| KBP1506G | 600 V, 15 A, VF = 0.95 V @ 7.5 A; 4-pin DIP package, no heatsink pad | Lacks integrated heatsink interface; requires larger PCB copper area for thermal management | Select where board space permits extended copper pour and lead-time favors ON Semi sourcing |
Compared with GBU15J-E3/51 and KBP1506G, KBJ15L06-TU offers the lowest VF (0.9 V) and best thermal path (1.5 °C/W) among 15A/600V bridges, enabling higher power density in thermally constrained industrial power supplies.

FAQ
What is the maximum operating temperature for KBJ15L06-TU?
The KBJ15L06-TU has a specified junction temperature range of -55°C to +150°C. Its average forward current derates to 15 A only when case temperature is maintained at +125°C with an appropriate heatsink; without heatsink, maximum usable IF(AV) drops to 3.9 A at the same case temperature.
Does KBJ15L06-TU require forced air cooling?
No - forced air cooling is not required. With a properly sized 200 mm × 200 mm × 5 mm aluminum heatsink, the device achieves RθJA = 6 °C/W and sustains 15 A continuously at +125°C case temperature. Natural convection suffices for ≤5 A loads in well-ventilated enclosures.
Is KBJ15L06-TU compliant with automotive qualification standards?
The KBJ15L06-TU itself is not AEC-Q101 qualified. However, Diodes offers automotive-grade variants (e.g., KBJ15L06Q) with PPAP documentation, IATF 16949 manufacturing, and AEC-Q101 stress testing - contact Diodes or Aetrix for qualified alternatives if automotive use is required.
Can KBJ15L06-TU be used in PCB-mount applications without chassis mounting?
Yes - the KBJ package is designed for direct PCB mounting with its integral heatsink pad. It supports any mounting position and requires no chassis attachment; thermal performance relies on copper area under the pad and optional external heatsink, not mechanical fastening to metal chassis.
