Key Parameters

Substitute Part Grouping Explanation

Substitution for the STTH8R04G-TR diode is determined exclusively by matching key electrical and mechanical parameters within the Diodes, Rectifiers category. Parameters strictly considered include maximum DC reverse voltage (Vr), average rectified current (Io), maximum forward voltage (Vf) at rated current, reverse recovery time (trr), reverse leakage current, package type, mounting style, supplier device package, operating temperature range, RoHS status, MSL rating, REACH status, and product status. Only parts meeting these criteria may be considered equivalent or substitute options under this product category.

Parameter Comparison

Engineering Selection Recommendations

Select substitute parts according to active product status. Ensure RoHS3 compliance aligns with application requirements. Confirm Moisture Sensitivity Level (1 - Unlimited) for compatibility in manufacturing environments. Review REACH status for specific regulatory needs that may affect component selection.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for substituting the STTH8R04G-TR diode?
A1: Substitution requires matching voltage - DC reverse (400 V), current - average rectified (8A), forward voltage at rated current, reverse recovery time, reverse leakage current, mounting type, package/case, supplier device package, operating temperature - junction, RoHS status, and product status.

Q2: Does package compatibility affect substitution?
A2: Yes, both the STTH8R04G-TR and SDURB840 use the TO-263-3, D2PAK (2 Leads + Tab), TO-263AB and are surface mount, confirming mechanical compatibility.

Q3: Are substitutes required to have the same reverse recovery time or forward voltage?
A3: Substitute diodes must fall within the provided reverse recovery time and forward voltage parameters. Both STTH8R04G-TR and SDURB840 meet these requirements.

Q4: How does environmental compliance impact substitute selection?
A4: RoHS3 compliance is met by both parts. REACH status should be checked against specific project or shipment requirements.

Q5: Can a substitute be considered if its operating temperature differs?
A5: The operating temperature - junction values should encompass the intended application environment. Both listed parts indicate suitable ranges for typical electronics use under specified parameters.

Q6: What should be checked regarding supply format and handling?
A6: Both the main and substitute parts are available in Tape & Reel packaging and possess Moisture Sensitivity Level 1 (Unlimited), supporting compatibility in standard assembly processes.
