Product details
Overview
KBJL410-TU from Diodes Incorporated is a 4A standard recovery bridge rectifier with 1000V peak repetitive reverse voltage (VRRM), 1.0V max forward voltage at 2A, and 10µA max reverse leakage at 25°C. It features glass-passivated die construction, UL-recognized "Green" molded plastic package (KBJL), and is rated for automotive-grade change control support upon request.
For engineers reviewing the KBJL410-TU datasheet, KBJL410-TU pinout, KBJL410-TU application, or KBJL410-TU equivalent, this part is selected for high-surge AC/DC front-end conversion in space-constrained power supplies where thermal resistance (RθJA = 24°C/W without heatsink) and RoHS-compliant lead-free termination are critical.
Technical Context
The KBJL410-TU integrates four standard-recovery diodes in a single-phase full-wave bridge configuration, optimized for line-frequency rectification (50/60Hz). Its 120A non-repetitive surge rating (8.3ms half-sine, TJ = 25°C) supports inrush current handling in offline SMPS inputs.
Thermal design relies on its low RθJC (7°C/W without heatsink) and compatibility with 35mm × 35mm × 1.7mm copper heatsinks to sustain 4A average output current at TC = +125°C. Junction capacitance is 40pF at 1MHz/4V, limiting high-frequency switching suitability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum reverse voltage the bridge withstands repeatedly without breakdown; defines input AC voltage headroom (e.g., 707V RMS). |
| IF(AV) | 4 A - Average DC output current capability with heatsink at TC = +125°C; sets continuous load capacity in linear or flyback PSUs. |
| VF Max | 1.0 V @ 2A - Forward voltage drop per diode pair under conduction; determines conduction loss (≈2W at 2A) and thermal rise. |
| IR Max | 10 µA @ 25°C - Reverse leakage current at rated VRRM; impacts standby power and high-impedance bias networks. |
| IFSM | 120 A (8.3ms) - Peak surge current tolerance; enables survival of cold-start inrush in TV/PC power supplies. |
| RθJA | 24 °C/W - Junction-to-ambient thermal resistance without heatsink; governs self-heating in compact PCB layouts. |
Pinout & Package
Package: KBJL - Molded plastic case, 4-pin single-phase bridge rectifier outline (D = 24.7–25.3 mm, E = 10.0–10.6 mm, L = 14.6–15.2 mm), matte tin-plated leads, RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| "Green" RoHS-compliant packaging | Meets Br/Cl <900ppm, Sb <1000ppm, and EU RoHS 3 (2015/863/EU); required for global market access. |
Applications
| TV Power Supply | PC Power Supply |
|---|---|

IC Role / Device Role / Timing Role: Mains-input bridge rectifier operating at 50/60Hz with intermittent high-load duty cycles. Use Value: Low RθJA (24°C/W) enables natural convection cooling in sealed enclosures; green compound meets regional environmental mandates. | Use Scenario: DIN-rail or open-frame AC-DC converters for industrial sensors and PLC I/O modules. IC Role / Device Role / Timing Role: Robust line-frequency rectifier supporting wide ambient temperature range (–55°C to +150°C). Use Value: Extended TJ range and 500µA IR at 125°C ensure stable performance in thermally demanding enclosures. |
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 1000V VRRM and 4A IF(AV), but GBU package (larger footprint, RθJA ≈ 30°C/W). | Requires more PCB area; lower surge rating (100A vs. 120A) limits inrush margin. | Choose when legacy GBU layout exists and thermal margin permits higher RθJA. |
| KBPC410 | Identical electrical specs (1000V/4A), but KBPC package (larger, stud-mount compatible, RθJA ≈ 18°C/W with heatsink). | Designed for bolt-down heatsinking; not suitable for dense SMT-reflow assembly. | Prefer when mechanical mounting and superior thermal dissipation outweigh size constraints. |
Compared with GBU10K and KBPC410, KBJL410-TU offers the smallest footprint among 4A/1000V bridges, highest surge rating, and optimized thermal resistance for PCB-constrained designs-making it ideal for modern compact power supplies requiring regulatory and environmental compliance.

FAQ
What is the maximum junction temperature for KBJL410-TU?
The KBJL410-TU has a specified operating junction temperature range of –55°C to +150°C. This allows reliable operation in high-ambient environments such as enclosed TV power supplies or industrial adapters. Derating curves confirm 4A average current is sustainable only when case temperature remains ≤+125°C, typically requiring minimal heatsinking or airflow.
Is KBJL410-TU suitable for high-frequency switching applications?
No-KBJL410-TU is a standard-recovery bridge rectifier with typical reverse recovery time (trr) not specified in the datasheet and junction capacitance of 40pF. It is intended for 50/60Hz line-frequency rectification only. For high-frequency SMPS (>20kHz), fast- or ultrafast-recovery alternatives (e.g., GBU10J or KBU10J) must be used to minimize switching losses and EMI.
Does KBJL410-TU require a heatsink for 4A continuous operation?
Yes-4A average current is rated only with heatsink at TC = +125°C. Without heatsink, the derating curve shows maximum IF(AV) drops to 2.7A at TC = +125°C and further to ~1.5A at TA = +70°C. PCB copper area (≥35mm × 35mm) or an external heatsink is necessary to maintain safe junction temperatures under full load.
How is the date code marked on KBJL410-TU?
The marking format is "Green KBJL410 YWW", where "Y" is the last digit of the year (e.g., "5" = 2025) and "WW" is the week code (01–53). This 2-digit date code appears adjacent to the part number on the body of the KBJL package and follows JEDEC-standard laser marking for traceability and lot control.
