Product details
Overview
KBJL606-TU from Diodes Incorporated is a 6A standard recovery bridge rectifier in KBJL package, rated for 600V repetitive peak reverse voltage (VRRM), with maximum forward voltage of 1.0V at 3A and leakage current ≤10µA at 25°C. It delivers high surge capability (135A @ 8.3ms) and operates from –55°C to +150°C, serving as the primary AC-to-DC conversion stage in compact off-line power supplies.
For engineers reviewing the KBJL606-TU datasheet, KBJL606-TU pinout, KBJL606-TU application, or KBJL606-TU equivalent, key selection criteria include VRRM margin for line-voltage transients, thermal resistance (RθJA = 28°C/W without heatsink), IF(AV) derating above 125°C case temperature, and compliance with RoHS, halogen-free, and UL E95060 requirements.
Technical Context
This single-phase full-wave bridge rectifier integrates four silicon diodes in a monolithic molded plastic package with glass-passivated junctions. Its standard recovery characteristic (trr not specified but implied by "standard recovery" classification) supports operation in 50/60Hz line-frequency applications where fast switching is unnecessary and cost-effective conduction efficiency is prioritized.
The device uses matte tin-plated leads solderable per MIL-STD-202 Method 208 and mounts directly to PCBs without discrete heatsinking for low-to-moderate power levels. Thermal performance is defined both with (RθJC = 2°C/W) and without (RθJA = 28°C/W) a 35mm × 35mm × 1.7mm copper heatsink, enabling design flexibility across TV, game console, and PC auxiliary power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands peak AC line voltages up to 424V RMS with safety margin for surges in universal-input SMPS front-ends. |
| IF(AV) | 6 A (with heatsink at TC = 130°C) - Supports continuous DC output currents up to 6A when thermally managed; drops to 2.5A without heatsink at TC = 125°C. |
| VF Max | 1.0 V @ 3A - Limits conduction loss to ≤3W at 3A, critical for thermal budget in enclosed power enclosures. |
| IR Max | 10 µA @ 25°C - Ensures minimal standby power loss in always-on auxiliary supplies. |
| IFSM | 135 A @ 8.3ms - Survives cold-start inrush into bulk capacitors without degradation. |
| RθJA | 28 °C/W - Defines worst-case PCB-only thermal path; requires layout with ≥3 cm² copper pour for 6A operation at ambient ≤50°C. |
Pinout & Package
Package: KBJL - Molded plastic, UL 94V-0 rated, 2.4g weight, dimensions per Diodes package outline (D = 24.7–25.3 mm, E = 10.0–10.6 mm, L = 14.6–15.2 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ~AC1 | AC Input Terminal 1 | One leg of AC input; connects to live or neutral depending on board orientation-symmetrical for bidirectional line connection. |
| ~AC2 | AC Input Terminal 2 | Second AC input leg; forms full-wave bridge input pair with ~AC1; no polarity sensitivity. |
| +DC | Positive DC Output | Anode of internal series-connected diodes; delivers rectified positive rail to bulk capacitor or regulator input. |
| –DC | Negative DC Output / Common Return | Cathode of internal series-connected diodes; serves as circuit ground reference for downstream DC-DC stages. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivation | Enhances long-term reliability under humidity and thermal cycling by preventing junction corrosion in industrial environments. |
| UL Recognized Component (E95060) | Validates construction safety and flammability compliance for end-equipment certification (e.g., IEC 62368-1) without additional system-level testing. |
| Lead-free & halogen-free ("Green") | Meets RoHS 3 (2015/863/EU) and automotive change-control readiness, supporting global environmental compliance and supply chain traceability. |
| High surge current rating | 135A non-repetitive peak enables robustness against lightning-induced line surges and transformer inrush in consumer-grade power supplies. |
Applications
| TV Power Supply | Game Console Power |
|---|---|
Use Scenario: Primary rectification in 50–100W off-line AC/DC adapters for LCD/LED TVs with universal input (90–264VAC). IC Role / Device Role / Timing Role: Full-wave bridge rectifier converting AC mains to unregulated DC bus prior to PFC and PWM controller stages. Use Value: 6A average current rating supports sustained load delivery; 600V VRRM accommodates 264VAC + 30% surge margin without breakdown. | Use Scenario: Input-stage rectification in compact external power bricks for gaming consoles requiring stable 12V/5V auxiliary rails. IC Role / Device Role / Timing Role: Off-line bridge rectifier feeding bulk capacitor and downstream buck converters powering SoC and memory subsystems. Use Value: Low VF (1.0V) minimizes conduction loss at 3–4A typical loads; RoHS/halogen-free compliance meets regional regulatory shipping requirements. |
| PC Auxiliary Power | Industrial Control PSU |
Use Scenario: Standby and +5VSB generation in ATX-compliant desktop PSUs using dual-output flyback topologies. IC Role / Device Role / Timing Role: Bridge rectifier supplying low-power auxiliary winding circuitry that remains active during system sleep states. Use Value: 10µA max IR at 25°C ensures <5mW standby dissipation; wide TJ range (–55°C to +150°C) supports operation in ventilated chassis. | Use Scenario: Rectification in DIN-rail mounted 24VDC power supplies for PLC I/O modules and sensor interfaces. IC Role / Device Role / Timing Role: Mains-fed bridge rectifier providing unregulated DC input to isolated DC/DC converters in harsh industrial environments. Use Value: UL E95060 recognition simplifies end-product safety approvals; glass passivation ensures reliability under vibration and condensation exposure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6K-E3/51 | Same 6A/600V rating, GBU package (larger footprint, RθJA ≈ 20°C/W), higher VF (1.1V @ 3A). | Requires more PCB area; better suited for forced-air-cooled industrial supplies than space-constrained consumer adapters. | Select if mechanical mounting compatibility with legacy GBU footprints is required and thermal headroom permits higher VF. |
| KBL606G | 6A/600V, KBL package (shorter lead pitch), slightly lower IFSM (120A), same VF and IR specs. | Compatible with automated insertion equipment optimized for KBL; lower surge margin may limit use in high-inrush applications. | Choose when KBL footprint matches existing pick-and-place tooling and surge events are limited to <120A. |
Compared with GBU6K-E3/51 and KBL606G, KBJL606-TU offers superior thermal resistance in its compact KBJL form factor and best-in-class surge rating (135A), making it optimal for high-density, cost-sensitive consumer power supplies where PCB real estate and transient immunity are critical.

FAQ
Is KBJL606-TU suitable for use without a heatsink?
Yes, KBJL606-TU can operate without a heatsink at up to 2.5A average forward current when case temperature is maintained at ≤125°C, per its derating curve. For 6A operation, a heatsink with RθJC ≤ 2°C/W (e.g., 35mm × 35mm × 1.7mm Cu) is required to limit junction temperature within –55°C to +150°C limits.
What does the "-TU" suffix indicate in KBJL606-TU?
The "-TU" suffix denotes tube packaging: 20 pieces per plastic tube, intended for manual or semi-automated assembly. It does not affect electrical or thermal specifications-identical to KBJL606 in all performance parameters and reliability characteristics.
Does KBJL606-TU meet AEC-Q200 stress test requirements?
No-KBJL606-TU is not qualified to AEC-Q200. While Diodes offers AEC-Q200-compliant bridge rectifiers (e.g., KBJL606Q), this standard part is intended for commercial/industrial applications. Automotive use requires explicit qualification documentation and PPAP submission.
How does the KBJL package compare to KBL in PCB layout?
KBJL has a longer body (L = 14.6–15.2 mm vs. KBL's ~13.5 mm) and wider lead spacing (e = 7.3–7.7 mm vs. KBL's ~5.0 mm), requiring adjusted pad pitch and courtyard clearance. Its larger footprint improves thermal dissipation but occupies ~15% more board area than KBL.
