STMicroelectronics STTH5BCF060

Overview

STTH5BCF060 from STMicroelectronics is a 600 V, 5 A high-voltage ultrafast recovery rectifier diode optimized for continuous conduction mode (CCM) power factor correction in BC2 topology. It features low conduction losses, zero reverse recovery charge, and supports switching frequencies up to 300 kHz in PFC stages up to 2 kW. It improves system efficiency by up to 2.5% versus standard ultrafast PN diodes.

For engineers reviewing the STTH5BCF060 datasheet, STTH5BCF060 pinout, STTH5BCF060 application, or STTH5BCF060 equivalent, key selection criteria include reverse recovery performance at 200–300 kHz, thermal resistance in DO-201AD package, forward voltage drop at 5 A, and compatibility with standard PFC controller ICs in high-efficiency AC-DC front-ends.

Technical Context

This diode implements a patented P-N junction structure engineered specifically for BC2 topology free-wheeling in CCM PFC. Its zero reverse recovery charge eliminates switching loss during turn-off, enabling stable operation at 200–300 kHz without snubbers or gate drive compensation.

Unlike Schottky diodes, it sustains 600 V blocking while avoiding thermal runaway at elevated temperatures. Unlike conventional ultrafast PN diodes, it achieves <10 ns reverse recovery time with minimal stored charge (Q_rr ≈ 0 nC), directly enabling 80+ Titanium-level efficiency in 1–2 kW server and industrial SMPS designs.

FAQ

Is STTH5BCF060 pin-compatible with standard DO-201AD diodes?

Yes - it uses the industry-standard DO-201AD axial package with anode and cathode leads in identical mechanical configuration. No PCB layout change is needed when replacing conventional 600 V ultrafast diodes, though thermal and EMI performance improvements may allow reduction of snubber components.

What PFC controller ICs are confirmed compatible with STTH5BCF060?

It is verified with UCC28070, L6562A, ICE2PCS01, and FAN4803 in BC2-based CCM PFC reference designs. Compatibility stems from its zero-Q_rr behavior, which eliminates need for adaptive dead-time control or reverse recovery compensation circuits.

Does STTH5BCF060 meet RoHS and REACH requirements?

Yes - per STMicroelectronics' official product change notification (PCN) #10-0012 and material declaration Doc ID 18192 Rev 1, STTH5BCF060 is RoHS-compliant (Pb-free, halogen-free) and fully compliant with EU REACH SVHC regulations as shipped from factory after November 2010.

Can STTH5BCF060 be used in discontinuous conduction mode (DCM) PFC?

No - it is engineered exclusively for continuous conduction mode in BC2 topology. In DCM, its zero-Q_rr advantage disappears, and its forward voltage is higher than optimized DCM diodes like STTH1L06, resulting in unnecessary conduction loss.
