Product details
Overview
GBU601 from Diodes Incorporated is a 6.0A standard recovery bridge rectifier with 100V maximum repetitive peak reverse voltage (VRRM), 1.0V forward voltage drop at 3A, and 5µA maximum reverse leakage current at 25°C. It features glass-passivated die construction, 1500VRMS case dielectric strength, and is rated for 175A peak surge current. It is designed for AC/DC power conversion in industrial power supplies and motor control circuits.
For engineers reviewing the GBU601 datasheet, GBU601 pinout, GBU601 application, or GBU601 equivalent, key selection criteria include its 100V VRRM, 6.0A average forward current rating with heatsink, thermal resistance of 2.2°C/W (junction-to-case), UL recognition (E95060), and RoHS-compliant lead-free plating - all critical for reliable mains-input rectification in cost-sensitive, through-hole mounted designs.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a compact GBU package. Its standard recovery characteristic (trr not specified but typical for standard recovery bridges) supports 50/60Hz line-frequency operation without significant switching loss concerns.
Rated for continuous 6.0A average output current when mounted on a 50mm × 50mm × 1.6mm copper heatsink, it delivers stable DC output under resistive or inductive loads. Derating is required for capacitive loads (−20% current rating), and its 127 A²s I²t fusing rating ensures robustness against short-duration line surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; defines safe AC input voltage limit (e.g., ≤70V RMS). |
| IF(AV) | 6.0 A - Average DC output current capability with heatsink; determines sustained power delivery capacity. |
| VF @ 3A | 1.0 V - Forward voltage per diode pair; directly impacts conduction loss (≈6W total at 6A DC output). |
| IR @ 25°C | 5 µA - Reverse leakage current; low value minimizes standby power loss and improves efficiency in high-impedance circuits. |
| IFSM | 175 A - Non-repetitive peak surge current (8.3ms half-sine); withstands common AC line transients and inrush events. |
| RθJC | 2.2 °C/W - Junction-to-case thermal resistance; enables thermal design using standard PCB copper heatsinking. |
| CT | 100 pF - Typical junction capacitance at 1MHz/4V; negligible impact on 50/60Hz rectification but relevant for EMI filtering. |
Pinout & Package
Package: GBU - 4-pin, single-in-line (SIP), through-hole plastic package with #6 screw mounting hole; 3.7g mass; UL 94V-0 rated material; tin-plated leads compliant with MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | Input AC terminal 1 | One of two AC input connections; symmetrical with AC2 for bidirectional line connection. |
| AC2 | Input AC terminal 2 | Second AC input; completes full-wave bridge input path; polarity-independent. |
| + | DC positive output | Anode of internal upper diode pair; delivers rectified positive DC output to load or filter capacitor. |
| – | DC negative output / return | Cathode of internal lower diode pair; serves as common DC return path and circuit ground reference. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enhances long-term reliability and moisture resistance; eliminates need for hermetic sealing in humid environments. |
| 1500VRMS dielectric strength | Ensures safe isolation between AC input and DC output sides under transient overvoltage conditions per UL standards. |
| UL Recognized (E95060) | Validates compliance with UL 60747-4 for discrete semiconductors; simplifies end-equipment safety certification. |
| Lead-free, RoHS-compliant finish | Meets EU RoHS 2015/863/EU requirements; supports environmentally regulated manufacturing and global market access. |
| 175A surge rating | Withstands 8.3ms half-sine surges up to 175A - exceeds IEC 61000-4-5 Level 3 line surge immunity requirements. |
Applications
| Industrial Power Supply | Motor Control Interface |
|---|---|
Use Scenario: AC mains-fed linear or unregulated DC power supply for PLC I/O modules and sensor interfaces.

Use Scenario: Input rectifier in isolated flyback LED drivers for commercial lighting fixtures operating from 120/230V AC. IC Role / Device Role / Timing Role: Provides isolated DC input to primary-side controller; operates continuously at partial load. Use Value: 5µA max reverse leakage minimizes no-load power consumption; UL recognition supports ENERGY STAR and DLC certifications. |
Use Scenario: Mains rectification in white goods (e.g., washing machine control boards, microwave oven logic supplies). IC Role / Device Role / Timing Role: Delivers stable DC bias to microcontroller, relay drivers, and display circuitry. Use Value: Through-hole GBU package enables mechanical robustness and vibration resistance; RoHS compliance meets global appliance regulations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6K (ON Semiconductor) | Same 6A/100V rating, but 1.1V VF max at 3A; slightly higher conduction loss. | Identical pinout and footprint; requires thermal verification due to +0.1V VF increase. | Acceptable where minor efficiency trade-off is acceptable and ON Semi sourcing is preferred. |
| KBU6M (Comchip) | 6A/100V, 1.05V VF max, 10µA IR at 25°C - higher leakage than GBU601. | Same GBU package; higher IR may affect standby power in energy-sensitive designs. | Use only if leakage sensitivity is low and Comchip supply chain alignment is required. |
Compared with GBU6K and KBU6M, GBU601 offers the lowest specified reverse leakage (5µA) and tightest VF tolerance (1.0V), making it optimal for high-efficiency, low-standby-power industrial and appliance designs where thermal margin and regulatory compliance are critical.

FAQ
What is the maximum operating temperature for GBU601?
The GBU601 has a junction temperature range of −55°C to +150°C and a storage temperature range of −55°C to +150°C. Its 6.0A average current rating assumes TJ = +150°C when mounted on a specified 50mm × 50mm × 1.6mm copper heatsink. Exceeding this junction temperature risks permanent degradation.
Is GBU601 suitable for capacitive-input filter applications?
No - the datasheet explicitly requires derating the average forward current by 20% for capacitive loads. Without derating, peak charging currents can exceed safe limits and accelerate wear-out. For such applications, use a higher-current-rated bridge or add inrush limiting.
Does GBU601 have automotive qualification?
GBU601 is not AEC-Q101 qualified. Diodes states that automotive-grade variants require specific change control, PPAP capability, and IATF 16949 manufacturing - these are not included in the standard GBU601 part number. Customers needing automotive qualification must contact Diodes directly for qualified alternatives.
How is polarity marked on the GBU601 package?
Polarity is marked on the body: the "+" and "–" symbols are laser-etched or molded adjacent to their respective terminals, and the AC inputs are unmarked but located symmetrically at opposite ends of the SIP package. The cathode bar (if present) aligns with the "+" terminal side.
