Product details
Overview
KBJL1010-TU from Diodes Incorporated is a 10A standard recovery bridge rectifier with 1000V peak repetitive reverse voltage (VRRM), 1.0V max forward voltage at 5A, and 10µA max reverse leakage at 25°C. It features glass-passivated die construction, UL-recognized status (E95060), and is optimized for AC/DC power conversion in TV, gaming console, and PC power supplies.
For engineers reviewing the KBJL1010-TU datasheet, KBJL1010-TU pinout, KBJL1010-TU application, or KBJL1010-TU equivalent, key selection criteria include VRRM rating, thermal resistance (RθJA = 19°C/W without heatsink), surge current capability (150A @ 8.3ms), and RoHS-compliant green molding compound.
Technical Context
This device integrates four standard silicon diodes in a single-phase full-wave bridge configuration, enabling efficient AC-to-DC conversion without external interconnection. Its glass-passivated junction ensures stable reverse blocking performance across -55°C to +150°C operating temperature range.
The KBJL1010-TU delivers 10A average rectified output current when mounted on a heatsink at TC = +120°C, or 2.8A without heatsink at TC = +130°C. Junction capacitance is 48pF at 1MHz/4V reverse bias, supporting predictable high-frequency behavior in switching-derived input stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000V - Withstands peak reverse voltage up to 1000V in AC line applications without breakdown |
| IF(AV) | 10A with heatsink - Sustains continuous DC output current of 10A when thermally managed at TC = +120°C |
| VF Max | 1.0V @ 5A - Low conduction loss improves efficiency in mid-power SMPS and linear power supplies |
| IR Max | 10µA @ 25°C - Minimal reverse leakage preserves regulation stability in high-impedance hold-up circuits |
| IFSM | 150A @ 8.3ms - Handles inrush surges from cold-started transformers or bulk capacitors |
| RθJA | 19°C/W - Thermal resistance enables PCB-level thermal design without mandatory heatsink in low-duty-cycle applications |
| Junction Cap. | 48pF @ 1MHz - Predictable capacitive loading aids EMI filter design in offline rectifier front-ends |
Pinout & Package
Package: KBJL - Molded plastic case with matte tin-plated leads, UL 94V-0 rated, weight ≈2.4g. Dimensions: 25.0mm × 10.3mm × 14.9mm (D × E × L).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| AC2 | Input AC terminal 2 | Second leg of AC input; completes full-wave bridge input path |
| + (Anode Output) | Positive DC output | Full-wave rectified positive rail; feeds bulk capacitor or downstream regulator |
| – (Cathode Output) | Negative DC output / common return | DC ground reference point; ties to system GND and bulk capacitor negative |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivation | Enhances long-term reliability under humid or thermally cycled conditions by preventing junction corrosion |
| UL Recognized (E95060) | Validates compliance with safety standards for end-equipment certification in consumer electronics |
| Lead-free & Halogen-free | Meets RoHS 3 and "Green" requirements (<900ppm Br/Cl, <1000ppm Sb) for global environmental compliance |
| High surge rating | Withstands 150A non-repetitive surge (8.3ms) - critical for surviving AC line transients and cold-start stress |
Applications
| TV Power Supplies | Gaming Console Power Units |
|---|---|
Use Scenario: Primary-side rectification in 100–300W off-line SMPS for flat-panel TVs. IC Role / Device Role / Timing Role: Full-wave bridge rectifier converting 100–240V AC mains to unregulated DC bus.

Use Scenario: Bulk rectification stage in 500W+ ATX v2.4 compliant power supplies. IC Role / Device Role / Timing Role: Main bridge rectifier feeding active PFC circuitry and primary-side switch. Use Value: 10A IF(AV) rating supports sustained loads; RθJA = 19°C/W allows layout flexibility on multilayer PCBs without dedicated heatsink. | Use Scenario: AC input conditioning in DIN-rail mounted programmable logic controller (PLC) power modules. IC Role / Device Role / Timing Role: Isolated AC-to-DC conversion front-end for 24V/48V control rail generation. Use Value: -55°C to +150°C TJ range ensures operation in unventilated enclosures; UL recognition simplifies industrial safety approvals. |
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 KBJL package, 1000V VRRM, but 1.1V VF @ 5A and 50µA IR @ 25°C | Slightly higher conduction loss and leakage; less suitable for low-noise or high-efficiency designs | Acceptable where cost sensitivity outweighs VF/IR optimization |
| KBPC1010 | Higher RθJA (25°C/W), larger KBPC package (32mm × 20mm), 1.1V VF @ 5A | Requires more PCB area and additional thermal management; not drop-in compatible | Only viable if KBJL footprint is unavailable and board space permits re-layout |
Compared with GBU10K and KBPC1010, the KBJL1010-TU offers superior thermal performance (RθJA = 19°C/W), lower forward voltage (1.0V), and tighter leakage (10µA), making it optimal for space-constrained, efficiency-critical AC/DC front-ends.

FAQ
What is the maximum junction temperature for KBJL1010-TU?
The KBJL1010-TU has an operating junction temperature range of -55°C to +150°C, verified per JESD-22-A108. This rating enables reliable operation in sealed enclosures or high-ambient environments such as game console chassis or industrial control cabinets without forced air cooling.
Is KBJL1010-TU suitable for use without a heatsink?
Yes - the KBJL1010-TU supports 2.8A average rectified current without a heatsink at TC = +130°C. Its RθJA of 19°C/W allows direct mounting on FR-4 PCBs with adequate copper pour, though derating applies above 70°C ambient per Figure 1 in DS45589.
Does KBJL1010-TU meet automotive qualification standards?
No - the KBJL1010-TU is not AEC-Q101 qualified. Diodes offers automotive-grade alternatives (e.g., KBJL1010Q) with PPAP documentation and IATF 16949 manufacturing, but this TU variant is intended for commercial/industrial applications only.
How does the KBJL1010-TU differ from KBJL1008-TU?
The KBJL1010-TU has a 1000V VRRM rating versus 800V for the KBJL1008-TU; all other electrical and mechanical specifications - including IF(AV), VF, IR, package, and pinout - are identical. Selection depends solely on required reverse voltage margin for the AC line input.
