Diodes Incorporated GBP208

Overview

GBP208 from Diodes Incorporated is a 2A standard recovery bridge rectifier with 800V maximum repetitive peak reverse voltage (VRRM), 1.05V forward voltage at 1A, and 5µA reverse leakage current at 25°C. It features glass passivated die construction, UL 94V-0 plastic package, and is optimized for AC/DC power supply input stages in industrial and consumer equipment.

For engineers reviewing the GBP208 datasheet, GBP208 pinout, GBP208 application, or GBP208 equivalent, key selection criteria include its 800V blocking rating, thermal resistance of 3°C/W (junction-to-case), surge capability of 75A (8.3ms), RoHS-compliant matte tin plating, and suitability for PCB-mounted low-cost power conversion designs.

Technical Context

This single-phase full-wave bridge rectifier integrates four silicon diodes in a monolithic GBP package to convert AC input to pulsating DC without external wiring. Its standard recovery characteristic (trr not specified, typical for general-purpose bridges) supports line-frequency operation up to 60Hz/50Hz with minimal switching loss trade-off.

The device operates across –55°C to +150°C junction temperature, with derated average forward current (1.2A without heatsink at 25°C ambient) and robust 150A non-repetitive surge rating (1ms). Thermal performance relies on direct case-to-heatsink conduction via the molded plastic body's metal tab interface.

GBP208 is available at Aetrix Electronics and suitable for industrial AC/DC power supplies, consumer wall adapters, and LED driver input stages requiring stable component supply, RoHS compliance, and UL recognition.

Supply support for GBP208 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, with design, manufacturing, and sales operations across Asia, Europe, and the Americas.

The GBP series belongs to Diodes' standard recovery bridge rectifier product line, engineered for cost-effective, high-reliability AC/DC conversion in mainstream power supplies where switching speed is secondary to ruggedness and thermal stability.

FAQ

What is the maximum junction temperature for GBP208?

The GBP208 has an operating junction temperature range of –55°C to +150°C, as specified in the Absolute Maximum Ratings table. This allows reliable operation in high-ambient environments such as enclosed industrial power supplies or appliance control boards, provided thermal design maintains TJ ≤ 150°C under worst-case load and ambient conditions.

Is GBP208 suitable for use without a heatsink?

Yes - GBP208 can operate without a heatsink at up to 1.2A average forward current when ambient temperature is maintained at +25°C, per the derating curve. However, sustained operation above 0.8A without heatsinking requires careful PCB copper area design and airflow evaluation to avoid exceeding the 150°C maximum junction temperature.

Does GBP208 meet automotive qualification standards?

No - GBP208 is not AEC-Q101 qualified. While Diodes offers automotive-grade variants in the same GBP family (e.g., GBP208Q), the standard GBP208 is intended for industrial and consumer applications. Automotive use requires explicit AEC-Q101 testing, PPAP documentation, and IATF 16949 manufacturing certification - none of which apply to this part number.

How does the GBP package differ from KBPC or GBU packages?

The GBP package is a compact 4-pin single-in-line (SIP) outline measuring 14.5 × 10.4 × 3.1 mm, with leads spaced 3.81 mm apart and a metal tab for thermal conduction. KBPC is larger (22.5 mm length) with wider lead spacing; GBU uses a different leadform and body shape. These differences prevent mechanical interchangeability despite identical electrical ratings.
