Product details

Overview

DTH3006FP from Diodes Incorporated is a 30A, 600V super-fast epitaxial rectifier diode in ITO-220AC package, featuring 2.4V forward voltage at 30A/25°C, 45ns reverse recovery time, and 100μA reverse leakage at 600V/25°C; used in high-efficiency AC-DC switching power supplies operating in continuous conduction mode (CCM) PFC stages.

For engineers reviewing the DTH3006FP datasheet, DTH3006FP pinout, DTH3006FP application, or DTH3006FP equivalent, key selection criteria include soft-switching behavior for EMI reduction, thermal resistance of 3.3°C/W (junction-to-case), avalanche energy rating of 20mJ, and RoHS-compliant matte tin-plated leads suitable for industrial and automotive-grade power conversion designs.

Technical Context

This super-fast rectifier employs epitaxial construction with glass passivation to achieve low Q_RR (427.1nC at 125°C) and controlled soft recovery-critical for minimizing switching losses and voltage overshoot in high-frequency boost PFC circuits. Its 600V V_RRM and 350A I_FSM support robust operation under transient surge conditions typical in universal-input offline SMPS.

The device operates across –55°C to +175°C junction temperature range and delivers stable performance up to 125°C case temperature, enabled by low R_θJC (3.3°C/W) when mounted on a specified fin-type heatsink (170mm × 170mm × 44mm). Its 160pF typical junction capacitance at 1MHz/4V DC supports predictable high-frequency modeling in circuit simulation.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar super-fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH30L06D	Same 600V/30A rating; VF = 2.2V @ 30A/25°C; tRR = 35ns; TO-220AC package	Lower VF and faster tRR, but no stated EAS rating; less robust under repetitive avalanche stress	Select for highest efficiency where surge immunity is secondary
IXYS MUR3060PT	600V/30A; VF = 2.5V @ 30A/25°C; tRR = 50ns; TO-247 package; EAS = 25mJ	Higher thermal mass and superior avalanche ruggedness; larger footprint and higher cost	Select for mission-critical industrial systems requiring extended surge endurance

Compared with STTH30L06D and IXYS MUR3060PT, DTH3006FP offers balanced trade-offs: lower cost than TO-247 alternatives, better avalanche rating than ST's offering, and ITO-220AC's optimized thermal-mechanical profile for finned heatsink mounting.

FAQ

What is the maximum junction temperature and how does it affect thermal design?

The DTH3006FP has an operating junction temperature range of –55°C to +175°C. Its 3.3°C/W junction-to-case thermal resistance is measured with a specific fin-type heatsink (170mm × 170mm × 44mm). At 30A continuous current and 2.4V forward drop, power dissipation is ~72W; using R_θJC, the case-to-ambient rise is ~238°C-so heatsink selection must ensure case temperature stays ≤150°C to maintain 25°C margin below T_Jmax.

Is DTH3006FP suitable for use in automotive applications?

DTH3006FP is not AEC-Q101 qualified per its datasheet. While it meets RoHS 3 and "Green" material definitions, Diodes explicitly states that automotive-grade parts require separate qualification (AEC-Q100/101/104/200), PPAP capability, and IATF 16949 manufacturing. For automotive PFC stages, consult Diodes' AEC-Q101-certified equivalents such as the DTHx006Q series.

How does the soft recovery characteristic reduce EMI in PFC circuits?

Soft recovery limits the rate of change of reverse current (di/dt) during turn-off, reducing high-frequency spectral content in switching node waveforms. With t_RR = 45ns and Q_RR = 427.1nC at 125°C, DTH3006FP avoids abrupt current collapse that couples noise into adjacent traces and magnetics-lowering conducted EMI by up to 8dB in 150kHz–30MHz CISPR-22 tests compared to standard fast recovery diodes.

Can DTH3006FP be paralleled for higher current handling?

Parallel operation is not recommended without external balancing-its V_F has ±0.15V typical spread at 30A, leading to current imbalance >25% between units. Thermal coupling is also asymmetric due to single-tab ITO-220AC mounting. For >30A applications, Diodes recommends using higher-rated devices (e.g., DTH4006FP) or multi-phase interleaved PFC instead of paralleling.
