Diodes Incorporated GBP808N

Overview

GBP808N from Diodes Incorporated is an 8A standard recovery bridge rectifier in GBP package, rated for 800V repetitive peak reverse voltage (VRRM), with maximum forward voltage of 1.05V at 4.0A and leakage current ≤1µA at 800V/25°C. It delivers 8A average rectified output current with heatsink at TC = +100°C and supports automotive-grade thermal operation from –55°C to +150°C junction temperature.

For engineers reviewing the GBP808N datasheet, GBP808N pinout, GBP808N application, or GBP808N equivalent, key selection criteria include VRRM rating, IF(AV) derating behavior, thermal resistance with/without heatsink, surge current capability (165A @ 8.3ms), and RoHS-compliant green packaging for industrial power supplies and AC-DC front-end stages.

Technical Context

This bridge rectifier integrates four silicon diodes in a single molded plastic GBP package with glass-passivated die construction, enabling reliable high-voltage AC-to-DC conversion without external interconnection. Its standard recovery characteristic (trr not specified, consistent with non-fast-recovery classification) suits line-frequency applications where switching losses are secondary to voltage blocking and thermal robustness.

The device features UL 94V-0 flammability-rated plastic housing, matte tin-plated leads compliant with MIL-STD-202 Method 208, and polarity indicator molded on the body. Thermal resistance junction-to-case is 3.2°C/W when mounted on a 150mm × 150mm × 2mm copper heatsink - critical for sustained 8A conduction in compact power supplies.

FAQ

What is the maximum case temperature for continuous 8A operation?

The GBP808N sustains 8.0A average forward current only when case temperature (TC) is held at +100°C or lower - achievable using a 150mm × 150mm × 2mm copper heatsink. Without heatsink, derating begins above +25°C ambient, limiting usable current to 1.5A at TC = +100°C per Figure 1.

Is GBP808N suitable for high-frequency switching applications?

No - GBP808N is a standard recovery bridge rectifier with no specified reverse recovery time (trr). Its design targets 50/60Hz line-frequency rectification. For SMPS or PFC stages operating above 20kHz, fast- or ultrafast-recovery alternatives (e.g., GBU8J or GP20B) are required to minimize switching losses and EMI.

Does GBP808N meet AEC-Q200 stress testing requirements?

GBP808N is not qualified to AEC-Q200. While Diodes offers AEC-Q200-qualified bridge rectifiers (e.g., GBP808Q), the standard GBP808N is intended for industrial and commercial use. Automotive applications require explicit AEC-Q200 qualification, PPAP documentation, and IATF 16949 manufacturing - contact Diodes for qualified variants.

How is polarity identified on the GBP808N package?

Polarity is indicated by a molded symbol on the top surface of the GBP package: a "+" sign adjacent to the positive DC output terminal and a "–" sign near the negative terminal. The AC input terminals (AC1 and AC2) are unmarked but located opposite the DC output side - confirmed by the mechanical drawing showing AC pins aligned with the shorter end of the rectangular body.
