Parameter Comparison

Engineering Selection Recommendations

Both the STPS1040 and STPF1040 are Active product status components manufactured by Diodes Incorporated. Both parts maintain identical electrical specifications, mechanical packaging, and compliance certifications. Selection between these parts is based on inventory availability and supply chain requirements. The STPF1040 currently maintains higher inventory levels (1014 Pcs) compared to the STPS1040 (863 Pcs). Both parts are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity classification, indicating equivalent environmental and regulatory compliance for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the STPF1040 be used as a direct replacement for the STPS1040?

A: Yes. The STPF1040 is a parametric equivalent with identical electrical ratings (400 V reverse voltage, 5 A average rectified current, 1.3 V forward voltage at 5 A, 35 ns reverse recovery time), identical mechanical packaging (TO-220-3 Full Pack, Isolated Tab, through-hole mounting), and identical compliance certifications (ROHS3 Compliant, REACH Unaffected, MSL 1).

Q: Are there any differences in the supplier device package designation?

A: The STPS1040 uses supplier device package ITO220AB (Type WX2), while the STPF1040 uses ITO220AB (Type WX). Both designations refer to the same TO-220-3 Full Pack with isolated tab mechanical form factor and are functionally equivalent for circuit board assembly and thermal management.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by equivalence in diode configuration (1 Pair Common Cathode), reverse voltage rating (400 V), average rectified current (5 A per diode), forward voltage (1.3 V @ 5 A), reverse recovery time (35 ns), reverse leakage current (10 µA @ 400 V), operating temperature range (-55°C to 150°C), and mechanical package (TO-220-3 Full Pack, Isolated Tab, through-hole).

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the STPS1040 and STPF1040 operate across the identical junction temperature range of -55°C to 150°C, ensuring equivalent thermal performance in target applications.

Q: What is the significance of the isolated tab in the TO-220-3 package?

A: The isolated tab designation indicates that the tab is electrically isolated from the semiconductor die, allowing for independent thermal management without electrical connection to the circuit. This feature is identical across both parts.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the STPS1040 and STPF1040 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for industrial and commercial electronic applications.
