Equivalent & Substitute Parts for 6A02-G General Purpose Rectifier Diode

Part Overview

The 6A02-G is an active general purpose rectifier diode manufactured by Comchip Technology, rated for 200 V DC reverse voltage and 6 A average rectified current. This through-hole component operates across a junction temperature range of -55°C to 125°C and is packaged in R-6 axial configuration. The device is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter tolerances while maintaining through-hole mounting compatibility and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6A02-G is determined by the following critical parameters:

Primary Electrical Criteria:

• Voltage - DC Reverse (Vr) rating must equal or exceed 200 V
• Current - Average Rectified (Io) must equal or exceed 6 A
• Voltage - Forward (Vf) must not exceed 1 V at 6 A operating point
• Speed classification must be Standard Recovery (>500ns, >200mA)

Mechanical & Compliance Criteria:

• Mounting type must be Through Hole
• Package configuration must be Axial
• RoHS3 compliance required
• Operating temperature range must accommodate -55°C to 125°C minimum

Two substitute parts meet these criteria: 1N5550 and GI752-E3/54. The 1N5550 operates at reduced current capacity (3 A versus 6 A) and therefore functions as a substitute only in applications where current demand does not exceed 3 A. The GI752-E3/54 maintains full 6 A current rating with improved forward voltage characteristics and extended temperature range.

Parameter Comparison

Engineering Selection Recommendations

For 6 A Applications: The GI752-E3/54 manufactured by Vishay General Semiconductor - Diodes Division is the direct substitute for the 6A02-G. Both devices maintain 200 V reverse voltage rating and 6 A current capacity. The GI752-E3/54 provides superior forward voltage performance (900 mV versus 1 V at 6 A) and extended upper temperature rating (150°C versus 125°C). Both are ROHS3 compliant with MSL 1 rating. Axial package configuration is compatible with through-hole PCB layouts designed for the original 6A02-G.

For Applications ≤ 3 A: The 1N5550 manufactured by Solid State Inc. is a valid substitute when circuit current requirements do not exceed 3 A. This device meets all electrical and compliance criteria at reduced current capacity. The 1N5550 offers extended temperature range (-65°C to 200°C) and lower reverse leakage current (1 µA versus 10 µA). Axial package configuration maintains through-hole compatibility.

Compliance Status: All three devices are ROHS3 compliant, EAR99 classified, and carry HTSUS code 8541.10.0080. Selection between main part and substitutes is based on current capacity requirements and thermal operating envelope of the target application.

Frequently Asked Questions (FAQ)

Q: Can the 1N5550 replace the 6A02-G in all applications?

A: The 1N5550 is a valid substitute only in applications where average rectified current does not exceed 3 A. The 6A02-G is rated for 6 A; the 1N5550 is rated for 3 A. Exceeding the 1N5550 current rating will result in device failure.

Q: What is the primary difference between the GI752-E3/54 and the 6A02-G?

A: Both devices are rated for 200 V and 6 A operation. The GI752-E3/54 exhibits lower forward voltage drop (900 mV versus 1 V at 6 A), resulting in reduced power dissipation. The GI752-E3/54 also supports higher maximum junction temperature (150°C versus 125°C). Package designations differ (P600 versus R-6), but both are axial through-hole configurations.

Q: Are package dimensions interchangeable between R-6 and P600 axial packages?

A: Both R-6 and P600 are axial through-hole packages formats. Physical dimensions may differ; verify PCB footprint compatibility before substitution. Axial lead spacing and body diameter should be confirmed against circuit board layout specifications.

Q: Do all three devices meet RoHS3 compliance?

A: Yes. The 6A02-G, 1N5550, and GI752-E3/54 are all ROHS3 compliant. All three devices carry REACH Unaffected or REACH Unaffected status where applicable.

Q: What is the reverse leakage current difference between these devices?

A: The 6A02-G exhibits 10 µA reverse leakage at 200 V. The 1N5550 exhibits 1 µA, and the GI752-E3/54 exhibits 5 µA at the same voltage. Lower reverse leakage reduces standby power consumption in high-impedance circuits.

Q: Can temperature range differences affect substitution decisions?

A: Yes. The 6A02-G operates from -55°C to 125°C. The GI752-E3/54 operates from -50°C to 150°C, and the 1N5550 operates from -65°C to 200°C. Select the substitute whose temperature range encompasses the target application's thermal environment.
