Vishay General Semiconductor - Diodes Division G3SBA60-E3/45

Overview

G3SBA60-E3/45 from Vishay General Semiconductor is a glass passivated single-phase bridge rectifier in GBU package, rated for 600 V repetitive peak reverse voltage (VRRM), 4.0 A average forward output current at TC = 100 °C, and 80 A non-repetitive surge current (IFSM). It delivers 1.0 V forward voltage at 2.0 A per diode and exhibits only 5 μA reverse leakage at 25 °C, serving as the AC/DC conversion stage in compact power supplies for consumer electronics.

For engineers reviewing the G3SBA60-E3/45 datasheet, G3SBA60-E3/45 pinout, G3SBA60-E3/45 application, or G3SBA60-E3/45 equivalent, key selection criteria include its 600 V blocking capability, PCB-mountable GBU case with 1500 VRMS dielectric strength, RoHS-compliant matte tin-plated leads, and thermal resistance of 26 °C/W (RθJA) under standard PCB mounting conditions.

Technical Context

This device implements a full-wave bridge configuration using four silicon diodes in a single in-line GBU package, enabling direct AC-to-DC conversion without external wiring. Its glass passivation ensures stable junction performance under humidity and thermal cycling, while the 1500 VRMS case dielectric strength supports safe isolation in mains-connected equipment.

The G3SBA60-E3/45 operates across –55 °C to +150 °C junction temperature range and maintains low IR (5 μA @ 25 °C) up to 600 V DC blocking, making it suitable for high-reliability, space-constrained rectification where thermal management relies on PCB copper pads (0.5" × 0.5") rather than heatsinks.

FAQ

What is the maximum junction temperature rating for the G3SBA60-E3/45?

The G3SBA60-E3/45 has a specified operating junction temperature range of –55 °C to +150 °C. This upper limit enables reliable operation in enclosed, thermally stressed environments such as sealed power adapters or motor drive control boards, provided thermal design (e.g., copper pad area, airflow) keeps actual TJ below 150 °C. Derating curves in the datasheet define allowable IF(AV) versus TC.

Does the G3SBA60-E3/45 require a heatsink for 4.0 A continuous operation?

No, the G3SBA60-E3/45 achieves its rated 4.0 A IF(AV) at TC = 100 °C-not TA-so it does not require an external heatsink when mounted on a PCB with 0.5" × 0.5" (12 mm × 12 mm) copper pads per terminal. The 26 °C/W RθJA value assumes this PCB layout; adding a heatsink lowers TC further but is unnecessary for nominal 4 A operation under defined mounting conditions.

What does the "E3/45" suffix mean in G3SBA60-E3/45?

The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads and halogen-free molding compound per Vishay specification. The "/45" indicates tube packaging containing 20 units, using Vishay's preferred package code 45. This ordering format ensures traceability, consistent solderability, and compliance with JESD 201 Class 1A whisker resistance requirements.

How does the G3SBA60-E3/45 compare to the G3SBA20 and G3SBA80 variants?

The G3SBA60-E3/45 shares identical package (GBU), thermal characteristics (RθJC = 5.0 °C/W, RθJA = 26 °C/W), and electrical test conditions with G3SBA20 and G3SBA80-but differs in VRRM: 200 V (G3SBA20), 600 V (G3SBA60-E3/45), and 800 V (G3SBA80). All three deliver 4.0 A IF(AV) and 80 A IFSM, so selection depends solely on required reverse voltage margin for the target AC input voltage.

Is the G3SBA60-E3/45 suitable for use in medical or automotive applications?

The G3SBA60-E3/45 is qualified for commercial-grade operation (–55 °C to +150 °C) and carries UL recognition E54214, but it is not AEC-Q101 qualified nor certified to ISO 13485. Vishay explicitly states its products are not designed for life-sustaining applications. Therefore, G3SBA60-E3/45 may be used in non-safety-critical auxiliary circuits of medical or automotive systems only after full system-level validation by the customer's engineering team.
