This class of ultrafast diode is typically used in high-frequency rectification, freewheeling, and snubber circuits in switch-mode power supplies, lighting ballasts, and motor drives where low switching losses matter. The 30 ns trr keeps reverse-recovery losses down in the 50–100 kHz range, which is where this part earns its keep. ST lists the STTH2R02QRL as Obsolete. If you are qualifying a replacement, the closest functional match will need the same 200 V / 2 A rating, 30 ns or faster trr, and a through-hole DO-15 footprint. ## 30 ns trr — the switching-speed spec that matters The 30 ns reverse recovery time is the key parametric that separates this diode from a standard recovery part. In a 100 kHz PFC boost stage, that 30 ns means the diode turns off fast enough to avoid excessive ringing and dissipation. If you are swapping in a replacement, the trr needs to be equal or faster — a 50 ns part will run hotter in the same spot. The forward voltage drop is 1 V at 2 A, which is typical for a 200 V ultrafast in this current class. ## DO-15 axial — the footprint constraint The DO-15 (DO-204AC) axial package is a through-hole leaded form factor. If your board has a hole pattern for a DO-15, any replacement must also be a DO-15 axial — a surface-mount equivalent would require a different PCB layout. There is no SMD version of this exact part; if you need a surface-mount diode with similar ratings, you would be looking at a different package family (e.g., SMB or SMC) and a different order code entirely.","metaTitle":"ST STTH2R02QRL Fast Recovery Diode, 200V 2A DO-15, 30ns trr","metaDescription":"ST STTH2R02QRL standard fast recovery diode, 200V 2A, 30ns trr, DO-15 axial.

The closest functional match will be a 200 V, 2 A ultrafast or fast-recovery diode in a DO-15 axial package with a trr of 30 ns or faster. Parts like the STTH2R02 (without the QRL suffix) or the STTH2R02RL may be functionally equivalent but verify the package and tape/reel suffix.

The STTH2R02QRL is only offered in the through-hole DO-15 axial package. For a surface-mount diode with similar voltage and current ratings, you would need to select a different part from the STTH family in an SMB or SMC package, such as the STTH2R02S (SMB) or STTH2R02U (SMC), but verify the trr and Vf match your design."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH2R02QRL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH2R02QRL when reusing this data.
