Product details
Overview
RS1JDFQ-13 from Diodes Incorporated is a 1.0A, 600V fast recovery surface-mount rectifier in the D-FLAT package, featuring 250ns reverse recovery time, 1.3V max forward voltage at 1A/25°C, and 5μA max reverse leakage at 600V/25°C. It delivers high-efficiency AC/DC conversion and reverse polarity protection in space-constrained power supplies.
For engineers reviewing the RS1JDFQ-13 datasheet, RS1JDFQ-13 pinout, RS1JDFQ-13 application, or RS1JDFQ-13 equivalent, key selection criteria include its AEC-Q101 qualification, 30A non-repetitive surge rating, sub-1.1mm profile, and thermal resistance of 26°C/W (junction-to-terminal), critical for automotive and industrial power rectification layouts.
Technical Context
This device operates as a unidirectional silicon junction rectifier with glass-passivated die construction, enabling stable performance across -55°C to +150°C ambient temperatures. Its fast recovery time (250ns) minimizes switching losses in high-frequency DC-DC converters and offline SMPS topologies.
The D-FLAT package provides low thermal resistance (RθJT = 26°C/W) and supports high-current capability despite its ultra-low height (<1.1mm). Polarity is marked by a cathode band, and terminals use matte tin annealed over copper leadframe for reliable solderability per MIL-STD-202.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Blocks up to 600V repetitive reverse voltage without breakdown, suitable for 400V AC input rectification with margin. |
| IO | 1.0 A @ TA = +100°C - Continuous average forward current rating under real-world board-level thermal conditions. |
| VF Max | 1.3 V @ IF = 1A, TJ = +25°C - Limits conduction loss to ≤1.3W peak during startup or transient load, aiding thermal design. |
| tRR | 250 ns - Enables operation up to ~2 MHz switching frequencies before recovery-related losses dominate efficiency. |
| IR Max | 5 μA @ VR = 600V, TJ = +25°C - Ensures minimal standby power loss in battery-backed or energy-sensitive systems. |
| RθJT | 26 °C/W - Allows direct thermal coupling to PCB copper for passive cooling without heatsinks in low-power adapters. |
| IFSM | 30 A @ 8.3ms - Withstands single half-sine surges from inrush or lightning-induced transients in industrial mains interfaces. |
Pinout & Package
Package: D-FLAT - Low-profile surface-mount plastic package (max height 1.10 mm), UL 94V-0 rated, with cathode band marking polarity. Dimensions: 4.60 × 2.80 mm footprint, 0.50–1.30 mm lead length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry node | Connected to AC input or switch-node side; requires adequate copper pour for thermal dissipation and current handling. |
| Cathode | Forward current exit node / output reference | Marked by band; ties to DC bus or filter capacitor; serves as return path for rectified current and ground reference in half-wave topology. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enhances long-term reliability under humidity and thermal cycling; eliminates need for conformal coating in harsh environments. |
| AEC-Q101 qualified | Validated for automotive under-hood applications including engine control modules and body electronics requiring extended temperature and vibration robustness. |
| Lead-free & halogen-free | Complies with RoHS 2 and JEDEC J-STD-020 Level 1 moisture sensitivity; enables lead-free reflow without delamination risk. |
| 30A surge rating | Supports cold-start inrush in 12V/24V DC systems without derating or external fusing in most industrial power entry designs. |
Applications
| Automotive Power Supply Protection | Industrial DC-DC Converter Input Stage |
|---|---|
Use Scenario: Reverse battery connection protection in 12V/24V vehicle ECUs and infotainment head units. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed in series with main power rail to prevent damage during incorrect battery installation. Use Value: Withstands 30A surge and operates reliably from -40°C to +125°C ambient, meeting ISO 16750-2 pulse test requirements. |
Use Scenario: Input rectification in isolated flyback or forward converters powering PLC I/O modules. IC Role / Device Role / Timing Role: High-speed rectifier converting 100–400kHz transformer secondary AC to DC, minimizing recovery loss. Use Value: 250ns tRR reduces switching loss by >35% vs. standard recovery diodes, improving converter efficiency above 85% at full load. |
| Consumer AC-DC Adapter Output | LED Driver Reverse Blocking |
Use Scenario: Secondary-side rectification in compact wall adapters for USB-C PD and IoT gateways. IC Role / Device Role / Timing Role: Fast-recovery output diode delivering regulated 5V/9V/12V with minimal voltage drop and EMI. Use Value: Sub-1.1mm D-FLAT height enables <12mm total adapter thickness; 1.3V VF limits conduction loss to <1.3W at 1A. |
Use Scenario: Reverse voltage blocking in constant-current LED drivers with capacitive dropper inputs. IC Role / Device Role / Timing Role: Prevents reverse current flow during AC zero-crossing in non-isolated LED lighting circuits. Use Value: 600V VRRM safely blocks 350V peak AC line transients; 5μA IR avoids LED dimming drift in low-current bias networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06U | Same 600V/1A rating but TO-277 package (height 1.8mm); tRR = 200ns; VF = 1.25V @ 1A. | Higher profile limits use in ultra-thin adapters; better surge rating (50A) suits higher-energy transients. | Select when board space allows taller profile and higher surge immunity is prioritized over height constraint. |
| MBR160LFS | Schottky diode (60V/1A); VF = 0.52V; no reverse recovery; IR = 100μA @ 25°C. | Lower VF improves light-load efficiency but insufficient for 400V AC rectification due to low VRRM. | Use only in low-voltage DC-DC outputs where 60V blocking suffices; not a functional replacement for 600V AC input stages. |
Compared with STTH1R06U and MBR160LFS, RS1JDFQ-13 uniquely balances 600V blocking, 250ns recovery, and sub-1.1mm height-making it the only option among the three qualified for AEC-Q101 and suitable for space-limited automotive and industrial rectifiers requiring full mains-voltage capability.

FAQ
What is the maximum operating temperature for RS1JDFQ-13?
The RS1JDFQ-13 has an operating junction temperature range of -55°C to +150°C and is rated for 1.0A average forward current at +100°C ambient. Its thermal resistance (RθJT = 26°C/W) allows safe operation at full current with appropriate PCB copper area, even in sealed enclosures.
Is RS1JDFQ-13 suitable for automotive applications?
Yes-RS1JDFQ-13 is AEC-Q101 qualified and PPAP capable, with tested performance across -40°C to +125°C ambient, 30A surge tolerance, and halogen-free "Green" construction. It is approved for use in engine control units, body electronics, and infotainment power rails per ISO 16750-2.
How does the D-FLAT package affect PCB layout?
The D-FLAT package (4.60 × 2.80 mm, <1.1mm height) requires a specific pad layout per Diodes' outline drawing DS38757: 2.25–2.95 mm length, 3.95–4.60 mm width, and 0.50–1.30 mm lead extension. Thermal pads must be ≥10 mm² copper on inner layers to achieve RθJA ≤ 93°C/W.
What is the reverse recovery behavior under high-temperature conditions?
At TJ = +125°C, VF drops to 0.94V (improving conduction loss), while tRR increases slightly but remains within specification. Reverse leakage rises to 0.25μA at 600V, ensuring minimal standby drain in battery-critical systems.
