Product details

Overview

DTH8L06D from Diodes Incorporated is an 8A, 600V hyper-fast epitaxial rectifier diode in TO220AC package, featuring 1.3V max forward voltage at 8A/25°C, 70ns reverse recovery time, and 8μA max reverse leakage at 600V/25°C. It serves as a primary output rectifier or freewheeling diode in high-frequency SMPS topologies operating in discontinuous or critical conduction mode.

For engineers reviewing the DTH8L06D datasheet, DTH8L06D pinout, DTH8L06D application, or DTH8L06D equivalent, key selection criteria include its soft-switching behavior, low thermal resistance (5°C/W junction-to-case), RoHS- and halogen-free "Green" construction, and suitability for compact, high-efficiency AC/DC adapters and LED drivers requiring fast recovery with minimal switching loss.

Technical Context

This hyper-fast rectifier employs epitaxial planar construction with glass passivation to achieve controlled minority-carrier lifetime, enabling soft reverse recovery with 70ns t_RR under IF = 0.5A / IR = 1.0A conditions. Its 600V V_RRM rating supports universal-input offline SMPS designs up to 265V_AC.

The device's low R_θJC of 5°C/W and tab-connected cathode configuration allow direct mounting to heatsinks for sustained 8A average current handling. Thermal performance is validated per JESD-51, with operation specified from –55°C to +150°C junction temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Supports 265V_AC input rectification with margin for line surges and ringing.
I_O	8 A - Sustained average forward current at T_C = 100°C, enabling compact 65–100W power supplies.
V_F	1.30 V max @ 8A, 25°C - Minimizes conduction loss; typical 0.94V at 125°C improves efficiency at elevated temperatures.
t_RR	70 ns - Enables operation in >100 kHz SMPS without excessive switching loss or EMI from hard recovery.
I_R	8 μA max @ 600V, 25°C - Ensures low standby power in no-load and light-load conditions.
R_θJC	5 °C/W - Allows effective thermal management using standard TO220 heatsinks for continuous 8A operation.
I_FSM	120 A @ 8.3 ms - Withstands inrush and transient overcurrents common during cold-start or short-circuit events.

Pinout & Package

IC Role / Device Role / Timing Role: Freewheeling diode in active-clamp forward or synchronous rectifier assist path.

Use Value: Soft recovery prevents voltage spikes across GaN FETs; TO220AC tab enables direct heatsinking in space-constrained layouts.

Home Appliance SMPS

Telecom Wall Adapter

Use Scenario: Main output rectifier in 36–48V/5A SMPS for washing machine control boards.

IC Role / Device Role / Timing Role: High-reliability rectifier handling repetitive surge currents during motor startup.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH8R06DJF	Same 600V/8A rating; 65 ns t_RR, 1.25V V_F max; TO220AC package with isolated tab.	Isolated tab simplifies heatsink mounting but adds 0.5Ω thermal resistance vs. cathode-connected tab.	Select when electrical isolation between cathode and heatsink is required; verify layout clearance for isolated tab.
ON Semiconductor MUR860E	600V/8A; 75 ns t_RR, 1.35V V_F max; TO220AC, cathode-tab connected.	Slightly slower recovery and higher V_F increase conduction loss by ~3% at 8A.	Acceptable where 5–10W efficiency margin exists; confirm thermal design accommodates higher V_F-related loss.

Compared with STTH8R06DJF and MUR860E, DTH8L06D offers the lowest combined conduction–switching loss profile due to its 1.3V V_F ceiling and 70ns t_RR, while its cathode-connected tab delivers superior thermal performance for high-duty-cycle applications.

FAQ

What is the maximum junction temperature and thermal resistance of DTH8L06D?

The DTH8L06D has a maximum junction temperature of +150°C and a typical junction-to-case thermal resistance (R_θJC) of 5°C/W, measured at the top center of the package body per JESD-51 standards. This value enables reliable 8A continuous operation when mounted on a properly sized heatsink with thermal interface material.

Is DTH8L06D suitable for automotive applications?

DTH8L06D is not AEC-Q101 qualified and is not intended for automotive safety-critical systems. While it operates from –55°C to +150°C, Diodes recommends contacting their automotive team for parts qualified to AEC-Q101 with PPAP capability and manufactured in IATF 16949-certified facilities.

How does the cathode-connected tab affect PCB layout and thermal design?

The metal tab is electrically connected to the cathode, requiring insulation from grounded heatsinks unless the cathode node is at system ground potential. This configuration provides the lowest possible thermal path (5°C/W) but mandates careful creepage/clearance verification-especially in high-voltage applications-to avoid unintended conduction paths.

What test conditions define the 70ns reverse recovery time?

The 70ns t_RR is measured under standardized conditions: IF = 0.5A, IR = 1.0A, and I_RR = 0.25A, using a 300μs pulse width and 2% duty cycle. These conditions reflect real-world switching behavior in discontinuous conduction mode (DCM) flyback converters, where soft recovery minimizes voltage ringing and EMI.
