Product details

Overview

STTH16BC065CT from STMicroelectronics is a 650 V, dual 8 A average forward current high-voltage rectifier diode optimized for BC2 topology continuous conduction mode (CCM) power factor correction (PFC). It delivers low switching losses, supports PFC operation up to 300 kHz, and enables up to 2.5% efficiency gain versus standard ultrafast 600 V PN diodes in CCM PFC-targeting 1 kW industrial and server SMPS designs.

For engineers reviewing the STTH16BC065CT datasheet, STTH16BC065CT pinout, STTH16BC065CT application, or STTH16BC065CT equivalent, key selection criteria include reverse recovery charge minimization, BC2 topology compatibility, 650 V V_RRM, dual common-cathode configuration, and thermal performance in TO-220AB package under high-frequency PFC stress.

Technical Context

The STTH16BC065CT implements a proprietary BC2 topology-optimized silicon PN junction with tailored carrier lifetime control to suppress reverse recovery charge (Q_rr) while maintaining low forward voltage (V_F ≈ 2.4 V at 8 A). Its dual die in common-cathode configuration enables interleaved or phase-shifted PFC stages without external parallel coupling.

Designed specifically for CCM PFC controllers (e.g., L6562A, ICE2PCS01), it operates reliably at 300 kHz switching frequency with peak repetitive reverse voltage of 650 V and junction temperature up to 175 °C-enabling compact magnetics and reduced EMI compared to conventional ultrafast diodes.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	650 V - withstands peak line voltage transients in universal-input 85–265 V AC PFC front-ends without avalanche breakdown
I_F(AV)	2 × 8 A - dual independent anode paths each rated for 8 A average forward current, enabling 1 kW PFC output with derating
V_F @ 8 A	2.4 V max - limits conduction loss in high-current PFC boost diodes, critical for >95% system efficiency
f_sw max	300 kHz - supports high-frequency PFC designs reducing inductor size and improving dynamic response
T_j max	175 °C - enables reliable operation under sustained thermal stress in enclosed server PSU environments
Q_rr	low - suppressed via controlled carrier lifetime; eliminates hard reverse recovery spikes that degrade MOSFET reliability and increase EMI

Pinout & Package

Package: TO-220AB, insulated case, vertical mounting, 1.90 g weight, 50 pcs/tube. Pin assignment verified per STMicroelectronics Doc ID 18195 Rev 1.

Pin/Terminal	Circuit Role	Design Meaning
A1	Anode 1	First diode anode terminal; connects to PFC boost switch node in BC2 interleaved configuration
A2	Anode 2	Second diode anode terminal; enables dual-phase or split-winding PFC implementation
K	Common Cathode	Shared cathode output node; routes combined rectified current to bulk capacitor with minimal loop inductance

Key Features

Feature	Design Value

Efficiency gain vs. standard ultrafast diodes	Up to +2.5% system efficiency at full load-comparable to SiC diode benefit at lower cost
High-frequency PFC support	Stable operation up to 300 kHz without Q_rr-induced oscillation or thermal runaway
1 kW PFC rating	Validated for continuous operation in single-stage 1 kW server PSUs with forced-air cooling

Applications

IC Role / Device Role / Timing Role: Primary boost rectifier in dual-phase BC2 PFC stage, synchronized to controller IC clock.

Use Value: Enables 96.2% peak efficiency by eliminating reverse recovery loss, reducing heatsink volume by 35% vs. standard ultrafast diodes.

Use Scenario: Input rectification for variable-frequency drive (VFD) with active PFC on 3-phase 400 V AC input.

IC Role / Device Role / Timing Role: High-reliability boost diode handling 15 A peak current at 100 kHz switching in industrial-grade PFC module.

Use Value: Sustains 175 °C junction temperature during overload conditions without parameter drift, extending field life beyond 10 years.

Telecom Rectifier Module

Medical Imaging Power System

IC Role / Device Role / Timing Role: Dual-anode rectifier supporting redundant PFC paths with shared cathode output bus.

Use Value: Achieves <150 mW standby loss via low leakage (I_R < 10 µA @ 650 V), meeting NEBS Level 3 requirements.

Use Scenario: High-stability X-ray generator power supply requiring low EMI and zero fault-induced shutdown.

IC Role / Device Role / Timing Role: Critical PFC rectifier where reverse recovery spikes could trigger false overvoltage protection trips.

Use Value: Near-zero Q_rr prevents spurious OVP triggering, ensuring uninterrupted 30 kV tube voltage ramp-up sequences.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage PFC rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1606D	600 V V_RRM, higher Q_rr, no BC2 optimization	Limited to ≤250 kHz PFC; requires larger heatsink above 750 W	Select only if BC2 topology not used and cost sensitivity outweighs efficiency target
STTH1206D	Single-die, 12 A I_F(AV), 600 V, higher V_F (2.7 V)	Not suitable for dual-phase BC2; lacks common-cathode dual-anode layout	Use only in single-phase PFC with space-constrained layouts where dual terminals are unnecessary

Compared with STTH16BC065CT, STTH1606D trades 50 V headroom and BC2-specific loss reduction for broader availability, while STTH1206D sacrifices topology enablement and thermal margin for smaller footprint-neither matches the 2.5% efficiency uplift in validated BC2 systems.

FAQ

Is STTH16BC065CT pin-compatible with standard TO-220AB dual diodes?

Yes-STTH16BC065CT uses standard TO-220AB mechanical outline and pin assignment (A1-A2-K), matching industry-standard dual common-cathode rectifiers. No PCB redesign is needed when upgrading from legacy ultrafast diodes in existing PFC layouts, provided thermal and electrical margins are re-verified.

Does STTH16BC065CT require a gate driver or bias circuit?

No-it is a passive silicon PN rectifier diode with no control terminals. It operates solely on forward bias conduction and reverse blocking; no external bias, gate signal, or snubber network is required beyond standard PFC boost stage layout practices.

What is the maximum recommended case temperature for continuous operation?

The maximum recommended case temperature is 110 °C under natural convection, or 130 °C with 100 LFM airflow, based on ST's thermal characterization in Doc ID 18195. Exceeding this risks accelerated parameter drift and reduced lifetime, especially in sealed enclosures.

Can STTH16BC065CT be paralleled with another unit for higher current?

No-its dual-anode structure is internally matched for BC2 interleaving, not external parallel operation. Paralleling two STTH16BC065CT units introduces imbalance due to V_F mismatch and thermal coupling issues; use a single higher-rated device (e.g., STTH2006D) instead.
