Equivalent & Substitute Parts Reference: 1N8034-GA

Part Overview

The 1N8034-GA from GeneSiC Semiconductor is a Silicon Carbide (SiC) Schottky diode intended for high-voltage, high-current rectification at 650 V and 9.4A. This component is supplied in a TO-257-3 Through Hole package, with a maximum forward voltage of 1.34 V at 10 A and negligible reverse recovery time. The 1N8034-GA is now classified as obsolete, necessitating consideration of suitable alternative models for continued design support and replacement in legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1N8034-GA are identified strictly by matching the following parameters: diode technology (SiC Schottky), reverse voltage rating (650 V), average rectified current rating (≥9.4A), reverse recovery time (0 ns), mounting type (Through Hole), and similar package styles. Only parts explicitly provided and matching these electrical and mechanical constraints are listed as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection between the 1N8034-GA and its substitute STPSC10C065RY should be based on product availability (both listed as obsolete) and regulatory compliance. The 1N8034-GA is identified as RoHS non-compliant, while STPSC10C065RY is specified as ROHS3 compliant and REACH unaffected. Both are classified under ECCN EAR99 and HTSUS 8541.10.0080. Moisture Sensitivity Level is 1 (Unlimited) for both types.

Frequently Asked Questions (FAQ)

Q1: What key parameters must match for substituting the 1N8034-GA with STPSC10C065RY?
Substitution requires equivalent SiC Schottky technology, reverse voltage of 650 V, average rectified current ≥9.4A, negligible reverse recovery time (0 ns), through hole mounting, and structurally comparable package types.

Q2: Are the package formats of TO-257-3 and I2PAK (TO-262-3 Long Leads) directly interchangeable?
Package interchangeability depends on mechanical fit and PCB layout; both are through hole but have different form factors. Mechanical compatibility should be confirmed with actual footprints and layouts.

Q3: Is there a difference in environmental and compliance status between the parts?
1N8034-GA is RoHS non-compliant. STPSC10C065RY is ROHS3 compliant and REACH unaffected. Compliance should be considered for applications requiring environmental certification.

Q4: Does the substitute offer similar or higher performance ratings?
STPSC10C065RY offers a higher current rating (10A vs. 9.4A) and matches the reverse voltage rating. All other operational parameters are in the provided comparison table.

Q5: How should the operating temperature range be considered?
There is a difference in the operating temperature range: 1N8034-GA is rated for -55°C to 250°C, while STPSC10C065RY supports -40°C to 175°C. Selection should match system requirements.

Q6: Is moisture sensitivity significant in this substitution?
Both parts are rated at Moisture Sensitivity Level 1 (Unlimited), ensuring straightforward handling in standard environments.
