GBU15L08

Overview

The GBU15L08 is a single-phase bridge rectifier manufactured by Diodes Incorporated, designed for high-efficiency power conversion. It features an average forward current rating of 15 A and a maximum repetitive peak reverse voltage of 800 V. The device utilizes glass passivated die construction to achieve a low maximum forward voltage drop of 0.9 V at 7.5 A, which reduces power dissipation and thermal stress. Electrical characteristics include a maximum leakage current of 10 µA at rated voltage and a typical junction capacitance of 160 pF. The component operates within a junction temperature range of -40°C to +150°C and supports peak forward surge currents up to 250 A under standard conditions.

Feature Summary

• Glass passivated die construction ensures stable electrical performance and long-term reliability.
• Low forward voltage drop design minimizes power loss and heat generation during operation.
• High surge current capability provides robust protection against transient load spikes.
• RoHS compliant and halogen-free 'Green' device suitable for environmentally regulated applications.

Applications

• General-purpose AC-to-DC power supply circuits
• Battery charging systems requiring high voltage tolerance
• Industrial equipment power modules

Procurement Notes

Verify the specific ordering suffix and packaging configuration when sourcing, as the standard tube contains 20 units. Confirm compliance with RoHS 3 directives and lead-free finish requirements prior to procurement. Ensure the supplier source aligns with authorized distribution channels to guarantee product authenticity and adherence to manufacturer specifications.

Selection Notes

Select this component for applications demanding 800 V blocking capability combined with 15 A continuous current handling. Evaluate thermal resistance parameters based on heatsink availability; without a heatsink, the average forward current derates significantly above ambient temperatures. Verify that the operating environment remains within the specified -40°C to +150°C junction temperature range to maintain rated performance.

Part Context

This part belongs to the GBU series of low forward voltage bridge rectifiers from Diodes Incorporated. It shares the GBU through-hole package form factor with other variants in the lineup but is distinguished by its specific 800 V / 15 A rating profile. The series emphasizes efficiency improvements over standard rectifiers through optimized silicon die design.

Replacement Considerations

Cross-reference with other GBU-series bridge rectifiers offering identical 800 V and 15 A ratings. Verify pinout compatibility and physical dimensions before substitution. Ensure replacement parts meet or exceed the original forward voltage and leakage current specifications to maintain system efficiency.

FAQ

What is the maximum repetitive peak reverse voltage rating?

The maximum repetitive peak reverse voltage (VRRM) is 800 V.

How does the forward voltage drop affect thermal management?

The low maximum forward voltage of 0.9 V at 7.5 A reduces power dissipation, thereby lowering thermal stress and potentially reducing cooling requirements compared to higher VF alternatives.

Is the device suitable for automotive applications?

Standard versions are not explicitly qualified for automotive use. For automotive applications requiring AEC-Q100/101/104/200 qualification and IATF 16949 manufacturing, direct contact with Diodes Incorporated is required.
