Product details

Overview

DFLR1600Q-7 from Diodes Incorporated is a 600 V, 1.0 A glass passivated surface-mount rectifier in the PowerDI®123 package, featuring 1.1 V max forward voltage at 1.0 A and 3 µA max reverse leakage at 25°C, optimized for AC-DC adapters, DC-DC converters, and freewheeling applications in compact power supplies.

For engineers reviewing the DFLR1600Q-7 datasheet, DFLR1600Q-7 pinout, DFLR1600Q-7 application, or DFLR1600Q-7 equivalent, key selection criteria include peak repetitive reverse voltage (600 V), thermal resistance junction-to-soldering point (6 °C/W), low-profile height (<1.1 mm), RoHS-compliant lead-free finish, and surge capability (25 A IFSM).

Technical Context

This device is a unidirectional silicon planar epitaxial rectifier with glass passivated junction, designed for high-reliability, automated SMT assembly. Its construction delivers stable reverse breakdown (min 600 V @ 10 µA) and low forward conduction loss across -40°C to +150°C operating range.

The PowerDI®123 package enables efficient heat transfer via cathode tab soldering to PCB copper, supported by validated R_θJS = 6 °C/W and R_θJA = 134 °C/W (free air). Total capacitance is 10 pF at 1 MHz/4 V, minimizing switching noise in high-frequency rectification.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - blocks up to 600 V repetitive reverse voltage without breakdown
I_O	1.0 A - continuous average forward current rating at 25°C ambient
V_F (max)	1.1 V @ 1.0 A - low conduction loss improves efficiency in low-voltage output stages
I_R (max)	3 µA @ 25°C - minimal leakage preserves standby power in energy-sensitive designs
I_FSM	25 A - handles 8.3 ms half-sine surge, supporting inrush and transient protection
R_θJS	6 °C/W - enables direct thermal path to PCB copper for reliable power dissipation
C_T	10 pF @ 1 MHz / 4 V - low junction capacitance reduces switching losses in SMPS

Pinout & Package

Package: PowerDI®123 - surface-mount, low-profile (height < 1.1 mm), molded green compound (UL 94V-0), cathode-band marked, matte tin-plated copper leadframe.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry	Connected to input/source side of rectification path; electrically tied to die substrate

IC Role / Device Role / Timing Role: Output rectifier converting transformer secondary AC to regulated DC.

Use Value: 1.1 V V_F minimizes conduction loss at 1 A load, improving efficiency over Schottky alternatives with higher leakage.

Use Scenario: Synchronous or freewheeling diode in buck-derived isolated/non-isolated converters.

IC Role / Device Role / Timing Role: Freewheeling path during high-side switch off-time; clamps inductive kickback.

Use Value: 25 A I_FSM withstands transient currents during startup or overload without failure.

Power Supply Front-Ends

Inverters (Low-Power)

Use Scenario: Input bridge or single-phase rectification in industrial control power modules.

IC Role / Device Role / Timing Role: General-purpose rectifier in line-input AC conditioning stages.

Use Value: 600 V V_RRM supports universal input (85–265 VAC) with margin against line surges.

Use Scenario: Anti-parallel diode across MOSFETs in motor drive half-bridges (e.g., fans, pumps).

IC Role / Device Role / Timing Role: Commutation path for inductive load current during PWM dead time.

Use Value: Low 10 pF C_T limits capacitive coupling noise in high dv/dt switching environments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar general-purpose rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SB160-TB	60 V V_RRM, 1 A, Schottky; lower V_F (~0.7 V) but higher I_R (500 µA @ 25°C)	Suitable only for low-voltage DC-DC outputs; not rated for AC line rectification	Select only when V_RRM ≤ 60 V and leakage tolerance > 100× higher than DFLR1600Q-7
1N4007G	1000 V V_RRM, 1 A, axial lead; V_F = 1.1 V, but R_θJA ≈ 65 °C/W, no SMT compatibility	Requires through-hole assembly and larger board area; unsuitable for automated high-density layouts	Choose only for legacy through-hole designs where thermal derating allows 1 A at elevated ambient

Compared with SB160-TB and 1N4007G, DFLR1600Q-7 uniquely balances 600 V blocking, SMT compatibility, low-profile packaging, and sub-µA leakage-making it optimal for modern compact AC-DC and DC-DC power stages where space, efficiency, and reliability are co-constrained.

FAQ

What is the maximum junction temperature for DFLR1600Q-7?

The DFLR1600Q-7 has an operating junction temperature range of -65°C to +150°C, verified per datasheet DS30602 Rev. 9-2. Thermal design must ensure T_J remains within this limit using the specified R_θJS = 6 °C/W path to soldered cathode tab.

Is DFLR1600Q-7 compatible with lead-free reflow profiles?

Yes. DFLR1600Q-7 features matte tin plating over copper leadframe and meets JEDEC J-STD-020 Level 1 moisture sensitivity. It is qualified for standard Pb-free reflow (peak 260°C, 10-second dwell) without preconditioning.

Does DFLR1600Q-7 have a built-in ESD protection structure?

No. The DFLR1600Q-7 is a passive rectifier without integrated ESD protection. System-level ESD robustness must be ensured externally via TVS diodes or layout practices, especially in adapter inputs exposed to human contact.

Can DFLR1600Q-7 replace DFLR1400Q-7 in a 400 V design?

Yes, with full functional and mechanical compatibility. Both share identical PowerDI®123 package, pinout, thermal characteristics, and 1.0 A I_O rating. DFLR1600Q-7 offers higher V_RRM (600 V vs. 400 V), providing additional margin for line surges or design reuse across voltage variants.
