Product details

600 V, 20 A fast recovery diode in common-cathode D2PAK

The 85 ns reverse recovery time (trr) keeps switching losses low, supporting efficient operation at elevated frequencies.

85 ns trr — switching performance for PFC and SMPS

The 85 ns reverse recovery time classifies this diode as a fast-recovery type (≤500 ns), making it suitable for hard-switching topologies where recovery charge directly impacts efficiency and EMI. Paired with a 1.55 V forward drop at 15 A, it balances conduction and switching losses for 1–3 kW PFC stages.

ST lists the STTH30L06CG as obsolete. Date-code and lot-trace verification are part of the sourcing process to avoid counterfeit or stale inventory.

Frequently asked questions

What is the replacement for STTH30L06CG?

No official replacement order code is recorded on the lifecycle entry. A functionally similar part in the same voltage and current class would need to be evaluated for pin-compatibility and trr — a cross-reference search against 600 V, 20 A fast-recovery diodes in D2PAK is the practical next step.
