Product details

Overview

GBJ602 from Diodes Incorporated is a 6A standard recovery bridge rectifier in GBJ package, rated for 200V repetitive peak reverse voltage (V_RRM), 1.0V max forward voltage at 3A, and 5µA max reverse leakage at 25°C. It features glass-passivated die construction, 1500V_RMS case dielectric strength, and 170A peak surge capability - used in AC/DC front-end conversion for industrial power supplies and motor control PCBs.

For engineers reviewing the GBJ602 datasheet, GBJ602 pinout, GBJ602 application, or GBJ602 equivalent, key selection criteria include V_RRM margin for line-voltage transients, thermal resistance (1.8°C/W junction-to-case), I_FSM rating for inrush handling, and UL recognition (E95060) for safety-compliant designs.

Technical Context

This single-phase full-wave bridge rectifier integrates four standard-recovery diodes in a common-cathode/common-anode configuration. Its 200V V_RRM supports 120/230VAC input with ≥2× safety margin, and 170A I_FSM withstands capacitor-charging surges without degradation.

Thermal performance is defined with a 75×75×1.6mm aluminum heatsink (R_θJC = 1.8°C/W), enabling 6.0A average output current at T_J = 150°C. Reverse leakage remains ≤5µA at 25°C and ≤500µA at 125°C, ensuring low standby loss in offline SMPS hold-up stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Withstands repetitive reverse voltage up to 200V, suitable for 230VAC mains with derating.
I_F(AV)	6.0 A - Maximum average forward current per element with heatsink at T_J = 150°C.
V_F Max	1.0 V @ 3A - Low conduction loss ensures <1.8W total dissipation in full-wave operation at rated DC load.
I_FSM	170 A (8.3ms half-sine) - Handles high-energy inrush currents during cold-start of transformer-fed supplies.
R_θJC	1.8 °C/W - Enables thermal design with standard PCB-mount heatsinks for continuous 6A operation.
I_R Max	5 µA @ 25°C - Minimizes no-load power loss in standby mode of AC-DC adapters and industrial PSUs.

Applications

Industrial Power Supply Input Stage

AC Motor Control Rectification

Use Scenario: Front-end AC/DC conversion in 30–100W industrial switch-mode power supplies.

IC Role / Device Role / Timing Role: Full-wave bridge rectifier converting 230VAC to pulsating DC before bulk capacitor and PFC stage.

Use Value: 200V V_RRM provides 2.3× margin over peak line voltage (325V), reducing risk of avalanche failure during surges.

Use Scenario: DC bus generation for single-phase inverter drives controlling fans, pumps, and conveyors.

IC Role / Device Role / Timing Role: Uncontrolled rectifier supplying stable DC link voltage to IGBT gate drivers and PWM controllers.

Use Value: 170A I_FSM sustains repeated motor startup currents without thermal runaway or parameter shift.

LED Driver Bulk Rectification

Appliance Power Conversion

Use Scenario: Off-line LED driver input stage in commercial lighting fixtures (e.g., troffers, streetlights).

IC Role / Device Role / Timing Role: Primary rectification element feeding constant-current buck or flyback controller ICs.

Use Value: 5µA IR at 25°C minimizes no-load consumption, supporting Energy Star Tier 2 standby power limits (<0.5W).

Use Scenario: Power supply for white goods (microwaves, washing machines) and HVAC controls.

IC Role / Device Role / Timing Role: Mains-input rectifier delivering DC to microcontroller, relay drivers, and sensor interfaces.

Use Value: UL E95060 recognition simplifies end-product safety approval and reduces time-to-market for Class I appliances.

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/200V rating, but GBU package (smaller footprint, lower I_FSM = 120A).	Limited surge immunity; unsuitable for high-inrush motor loads or capacitor-input filters with >1000µF.	Select only when board space is constrained and surge energy is below 72A²s (I²t).
KBP202 (Comchip)	Identical GBJ package, 6A/200V, but VF = 1.1V (vs. 1.0V) and IR = 10µA @ 25°C.	Higher conduction loss increases thermal stress in sealed enclosures above 50°C ambient.	Acceptable for cost-sensitive consumer applications where 0.1V VF delta and 5µA IR delta are tolerable.

Compared with GBU6K and KBP202, GBJ602 offers superior surge robustness (170A vs. 120A/-) and tighter leakage control (5µA vs. -/10µA), making it preferred for industrial-grade reliability and thermally demanding deployments.

FAQ

What is the maximum operating temperature for GBJ602?

GBJ602 has a junction operating temperature range of –55°C to +150°C. Its 6.0A average current rating assumes T_J = +150°C with a specified 75×75×1.6mm aluminum heatsink. Derating is required above 125°C ambient without forced cooling.

Is GBJ602 suitable for use without a heatsink?

No - GBJ602 requires a heatsink to sustain its rated 6.0A I_F(AV). Without heatsinking, the device is limited to ~1.5A continuous current due to R_θJA exceeding 50°C/W. For low-power applications (<1A), chassis mounting or copper pour may suffice.

Does GBJ602 meet automotive qualification standards?

GBJ602 is not AEC-Q101 qualified. Diodes offers automotive-grade variants (e.g., GBJ602Q) with PPAP documentation, IATF 16949 manufacturing, and extended temperature validation. Standard GBJ602 is intended for industrial and commercial use only.

How is polarity marked on the GBJ602 package?

Polarity is molded directly onto the plastic body: "+" indicates the common anode (DC positive) terminal, "–" indicates the common cathode (DC negative) terminal, and "~" symbols mark the two AC input pins (AC1 and AC2). No silkscreen is used - markings are embossed.
