Product details

Overview

DTH3006PT from Diodes Incorporated is a 30A, 600V super-fast epitaxial rectifier diode in TO247-2L package, designed for high-efficiency power switching circuits with soft recovery characteristics, 2.4V max forward voltage at 30A/25°C, and 27.8ns typical reverse-recovery time-used in AC-DC front-end rectification of industrial SMPS.

For engineers reviewing the DTH3006PT datasheet, DTH3006PT pinout, DTH3006PT application, or DTH3006PT equivalent, key selection criteria include peak repetitive reverse voltage (600V), average output current rating (30A @ TC=120°C), thermal resistance (1°C/W junction-to-case), soft-switching capability, and automotive-grade variant availability (DTH3006PTQ).

Technical Context

This super-fast rectifier employs epitaxial planar construction with glass passivation to achieve low QRR (95.8nC @ 25°C) and controlled soft recovery-critical for reducing EMI and snubber losses in high-frequency switching topologies like LLC resonant converters and PFC boost stages.

Its TO247-2L package enables direct mounting to heatsinks with verified 1°C/W R_θJC, supporting continuous 30A conduction at case temperatures up to +120°C while maintaining <100µA reverse leakage at 600V/25°C and <1mA at 125°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Withstands peak reverse voltage in bridge or single-phase rectifier configurations without breakdown.
I_O	30 A @ T_C = +120°C - Sustains continuous DC output current when mounted on fin-type heatsink (100×100×5mm).
V_F	2.4 V max @ I_F = 30A, T_J = +25°C - Limits conduction loss to ≤72W per device at full load, enabling high-efficiency designs.
t_RR	27.8 ns typ @ I_F = 1A - Enables operation up to ~300kHz switching frequency before recovery-related losses dominate.
Q_RR	95.8 nC typ @ T_J = +25°C - Low stored charge reduces turn-off switching loss and di/dt-induced voltage spikes.
R_θJC	1 °C/W - Allows precise thermal modeling: ΔT_J-C = 30W × 1°C/W = 30°C rise at full load, simplifying heatsink sizing.
E_AS	20 mJ - Withstands single-pulse avalanche energy during transient overvoltage events without failure.

Pinout & Package

Package: TO247-2L (Type HE), molded plastic with UL 94V-0 rating, matte tin-plated leads, 5.9g weight. Polarity marked on top view: anode and cathode terminals clearly identified per datasheet diagram.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Lead 1)	Input current entry point	Connected to AC input or switch node; must handle full surge current (I_FSM = 350A, 8.3ms).
Cathode (Lead 2)	Output current exit point	Drives bulk capacitor or downstream converter; electrically tied to heatsink mounting surface in standard layout.

Key Features

Feature	Design Value
Soft, super-fast switching	27.8ns t_RR with low IRM (3.57A) minimizes voltage overshoot and EMI generation during turn-off.
Glass passivated die	Enhances long-term reliability under humidity and thermal cycling stress, meeting industrial lifetime requirements.
600V peak reverse rating	Supports 400VAC input systems with 1.5× safety margin, suitable for universal-input SMPS (85–265VAC).
RoHS 3 & "Green" compliant	Halogen-free (<900ppm Br/Cl, <1000ppm Sb) and lead-free finish ensures compliance with EU environmental directives.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DTHP30R07PT	Lower V_F (1.75V typ @ 30A), improved t_RR (22ns), same TO247-2L package	Direct drop-in replacement with higher efficiency; recommended for new designs per Diodes notice	Select for next-gen designs targeting ≥0.5% system efficiency gain and reduced heatsink size.
STTH30L06D	Same V_RRM/I_O, but higher V_F (2.7V), slower t_RR (45ns), TO247AC package	Compatible footprint but requires thermal redesign due to 1.3°C/W R_θJC	Acceptable for legacy board reuse where DTH3006PT is obsolete, but verify thermal margin.

Compared with DTH3006PT, DTHP30R07PT delivers measurable efficiency and thermal improvement with identical mounting, while STTH30L06D offers second-source availability at the cost of higher conduction loss and reduced switching performance.

FAQ

Is DTH3006PT suitable for automotive applications?

No-DTH3006PT is not AEC-Q101 qualified. Diodes offers the automotive-compliant DTH3006PTQ variant under a separate datasheet, which undergoes additional qualification testing for temperature cycling, humidity, and mechanical shock per automotive standards.

What is the maximum allowable case temperature for continuous 30A operation?

The datasheet specifies I_O = 30A at T_C = +120°C. Operation above this temperature requires linear derating per Figure 1; at T_C = +130°C, maximum current drops to ~27A, and junction temperature must remain ≤175°C with R_θJC = 1°C/W.

Does DTH3006PT support paralleling for higher current capacity?

Paralleling is not recommended due to V_F mismatch across units-even small forward voltage differences cause current imbalance. For >30A systems, use a single higher-rated device (e.g., DTHP30R07PT) or multi-phase architecture instead.

How does the "soft switching" characteristic affect circuit design?

Soft switching reduces di/dt-induced voltage spikes and EMI, allowing smaller snubber components and relaxed layout constraints. It also lowers dynamic losses in synchronous rectifiers sharing the same node, improving overall converter efficiency by 0.3–0.8% in 100–300kHz designs.
