Product details

Overview

DTH3006D from Diodes Incorporated is a 600V, 30A super-fast epitaxial rectifier diode in TO220AC package, optimized for continuous conduction mode (CCM) power factor correction (PFC) stages and high-frequency switching power supplies. It delivers 2.4V forward voltage at 30A/25°C, 45ns reverse recovery time, and 100μA leakage at 600V/25°C.

For engineers reviewing the DTH3006D datasheet, DTH3006D pinout, DTH3006D application, or DTH3006D equivalent, key selection criteria include soft recovery behavior, thermal resistance (1°C/W junction-to-case), avalanche energy rating (20mJ), and RoHS-compliant green packaging with matte tin leads.

Technical Context

This device employs epitaxial planar construction with glass passivation to achieve fast, soft reverse recovery-critical for minimizing EMI and voltage overshoot in CCM PFC boost converters. Its 600V V_RRM and 350A non-repetitive surge rating support robust operation under transient line conditions.

The TO220AC package provides direct heatsink mounting capability, with verified R_θJC = 1°C/W when mounted on a 100mm × 100mm × 5mm aluminum heatsink. Junction temperature range spans –55°C to +175°C, enabling use in industrial and automotive-adjacent power systems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Blocks peak line voltages up to 600V in universal-input PFC and SMPS front-end designs
I_O	30 A @ T_C = +110°C - Sustains continuous output current in thermally constrained enclosures
V_F	2.4 V @ 30A/25°C - Reduces conduction loss in high-current PFC diode position
t_RR	45 ns - Enables soft-switching behavior with low dV/dt-induced ringing in >100kHz topologies
R_θJC	1 °C/W - Allows predictable thermal design with standard TO220 heatsinking
E_AS	20 mJ - Withstands inductive turn-off energy without failure in unclamped inductive loads
I_R	100 μA @ 600V/25°C - Ensures low standby leakage in offline power supplies

Pinout & Package

Package: TO220AC (Type WX), single-diode configuration with anode and cathode terminals on the lead frame and metal tab (cathode-connected tab). Mounting tab is electrically connected to cathode.

Pin/Terminal	Circuit Role	Design Meaning
Lead 1 (Left)	Anode	Main current entry point; connects to AC input or switch node in boost PFC
Lead 2 (Center)	Cathode	Main current exit; ties to DC bus capacitor positive rail
Metal Tab (Back)	Cathode	Electrically tied to Lead 2; provides low-inductance thermal path to heatsink

Key Features

Feature	Design Value
Soft, super-fast switching	45ns t_RR with controlled I_RM = 9.1A and Q_RR = 426.5nC at 125°C - reduces EMI and snubber stress
Glass passivated die	Enhanced moisture resistance and long-term reliability under thermal cycling and humid environments
CCM PFC optimization	Low stored charge and soft recovery enable stable operation in continuous conduction mode without oscillation
Green, RoHS-compliant construction	Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb) and matte tin-plated leads

Applications

Use Scenario: 1.5kW programmable DC power supply with active front-end rectification.

IC Role / Device Role / Timing Role: Output rectifier in high-frequency LLC resonant converter secondary side.

Use Value: 30A average current rating and 1°C/W R_θJC allow compact heatsink integration in enclosed chassis.

EV Onboard Charger (OBC) Front-End

Renewable Energy Inverter Input Stage

IC Role / Device Role / Timing Role: Freewheeling diode in boost pre-regulator stage handling PV array voltage up to 1000VDC.

Use Value: Low 2.4V V_F at 30A reduces conduction losses by ~1.2W vs. standard ultrafast diodes, improving system efficiency.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH30L06S	Same 600V/30A rating; 2.2V V_F @ 30A/25°C; 50ns t_RR; TO220AC package	Slightly lower V_F but longer t_RR - may require larger snubber in high-dV/dt PFC designs	Prefer where conduction loss dominates over switching loss
IXYS MUR3060CT	Dual common-cathode configuration; 600V/30A per diode; 2.1V V_F; 60ns t_RR; TO247 package	Requires PCB layout change (TO247 footprint); higher thermal resistance (0.8°C/W typical but requires larger heatsink area)	Choose only if dual-diode topology or higher surge margin is required

Compared with STTH30L06S and MUR3060CT, DTH3006D offers the shortest reverse recovery time (45ns) and lowest thermal resistance in TO220AC, making it optimal for space-constrained, high-frequency CCM PFC where EMI and thermal management are critical.

FAQ

Is DTH3006D suitable for automotive applications?

No-DTH3006D is not AEC-Q101 qualified. While its –55°C to +175°C operating range supports harsh environments, Diodes explicitly states that automotive-grade versions require separate qualification (PPAP, IATF 16949 manufacturing, AEC-Q101 testing) and must be requested directly through their automotive sales team.

What is the thermal performance when mounted on a PCB without external heatsink?

Without a heatsink, DTH3006D's junction temperature rises rapidly: at 30A, R_θJA exceeds 40°C/W. The datasheet specifies R_θJC = 1°C/W only with proper heatsink mounting. For PCB-only use, derate to ≤3A continuous to avoid exceeding 175°C junction temperature.

Does the metal tab carry electrical potential, and how should it be isolated?

Yes-the metal tab is electrically connected to the cathode terminal. When mounting to a heatsink, use an insulating washer and shoulder washer to prevent shorting. Ensure isolation voltage rating ≥600V and thermal interface material compatible with matte tin plating.

How does DTH3006D's soft recovery compare to standard ultrafast diodes?

DTH3006D exhibits soft recovery with I_RM = 9.1A and Q_RR = 426.5nC at 125°C, resulting in slower current decay and reduced dI/dt-induced voltage spikes. Standard ultrafast diodes typically show sharper turn-off and higher peak reverse current, increasing EMI and snubber losses in high-frequency PFC.
