Product details
Overview
RS1JDF-13 from Diodes Incorporated is a 1.0A, 600V fast recovery surface-mount rectifier in the low-profile D-FLAT package (1.1 mm max height), with VF ≤ 1.3 V at 1 A and trr = 250 ns. It delivers high-efficiency AC/DC conversion in compact power supplies and meets AEC-Q101 for automotive-grade reliability.
For engineers reviewing the RS1JDF-13 datasheet, RS1JDF-13 pinout, RS1JDF-13 application, or RS1JDF-13 equivalent, key selection criteria include peak repetitive reverse voltage (600 V), fast recovery time (250 ns), thermal resistance (RθJT = 26 °C/W), surge rating (30 A), and RoHS-compliant, halogen-free D-FLAT packaging.
Technical Context
This device operates as a unidirectional silicon PN junction rectifier optimized for high-frequency switching applications. Its glass-passivated die construction ensures stable reverse leakage (<5 µA at 600 V, 25°C) and robust surge tolerance (30 A, 8.3 ms half-sine).
The D-FLAT package enables low-inductance, low-thermal-resistance mounting on FR-4 PCBs, with RθJA = 93 °C/W and RθJT = 26 °C/W. Reverse recovery is characterized under IF = 0.5 A / IR = 1.0 A / IRR = 0.25 A per JEDEC standard test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands peak reverse voltage up to 600 V without breakdown, enabling use in 400 V DC bus systems with safety margin. |
| IO (TA = +100°C) | 1.0 A - Continuous average forward current rating at 100°C ambient, suitable for thermally constrained SMT layouts. |
| VF (IF = 1 A, TJ = 25°C) | ≤1.3 V - Low forward drop minimizes conduction loss and self-heating in high-duty-cycle rectification stages. |
| trr | 250 ns - Fast recovery reduces switching losses and EMI in SMPS operating above 50 kHz. |
| IFSM | 30 A - Handles short-duration inrush/surge events (e.g., cold-start in DC-DC converters) without failure. |
| IR (VR = 600 V, TA = 25°C) | ≤5 µA - Low leakage preserves efficiency in high-impedance hold-up or standby circuits. |
| RθJT | 26 °C/W - Enables direct heat transfer from junction to PCB pad, critical for thermal management in sealed enclosures. |
Pinout & Package
Package: D-FLAT (surface-mount, single-ended, cathode-banded, 2-terminal device). Dimensions: 4.60 × 2.80 × 1.10 mm (L × W × H), weight ≈ 0.035 g. Molded green compound, UL 94V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC input or transformer secondary; must be routed with low-inductance trace to minimize ringing. |
| Cathode (marked by band) | Forward current exit / DC output node | Connects to bulk capacitor or downstream converter input; serves as reference for snubber placement. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Ensures long-term stability of reverse characteristics and immunity to moisture-induced degradation in humid environments. |
| Fast recovery time (250 ns) | Reduces reverse recovery charge (Qrr), lowering switching loss and enabling higher-frequency operation than standard rectifiers. |
| AEC-Q101 qualification | Validated for automotive power modules, including engine control units and body electronics requiring extended temperature (-55°C to +150°C) and reliability compliance. |
| D-FLAT low-profile package | Enables <1.1 mm board height-critical for ultra-thin adapters, USB-C PD chargers, and space-constrained industrial sensors. |

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 VRRM (600 V), IO (1 A), but TO-277 package (higher profile, RθJA = 70 °C/W); VF = 1.25 V typical. | Requires larger PCB footprint and less efficient thermal dissipation; not AEC-Q101 qualified. | Prefer when legacy TO-277 footprint compatibility is required and automotive qualification is unnecessary. |
| SB1J-E3/54 | D-FLAT package, same pinout, but slower trr (500 ns); VF = 1.1 V typical; no AEC-Q101 certification. | Limited to lower-frequency (<100 kHz) SMPS where EMI and switching loss are less critical. | Select only for cost-sensitive industrial applications where AEC-Q101 and sub-300 ns recovery are not mandated. |
Compared with STTH1R06U and SB1J-E3/54, RS1JDF-13 uniquely combines AEC-Q101 qualification, 250 ns recovery, and D-FLAT low-profile packaging-making it optimal for next-gen automotive and space-constrained high-frequency power designs where thermal performance and reliability are co-prioritized.

FAQ
What is the maximum junction temperature for RS1JDF-13?
The RS1JDF-13 has an operating junction temperature range of –55°C to +150°C, verified per AEC-Q101 stress testing. At 100°C ambient, its 1.0 A IO rating is maintained; derating begins above that point per Figure 1 in DS37258. Thermal design must account for RθJT = 26 °C/W to avoid exceeding 150°C under worst-case load.
Is RS1JDF-13 suitable for synchronous rectification topologies?
No-RS1JDF-13 is a passive PN junction rectifier, not a MOSFET-based synchronous device. It lacks gate control and cannot replace active synchronous rectifiers. However, its 250 ns trr and low VF make it a high-performance alternative to standard recovery diodes in quasi-resonant or fixed-frequency flyback converters where synchronous control is impractical.
Does RS1JDF-13 require a heatsink in typical applications?
No external heatsink is required. With RθJT = 26 °C/W and RθJA = 93 °C/W on standard FR-4, the device remains within safe junction limits at 1.0 A and 100°C ambient when mounted on ≥100 mm² 2-oz copper pour. Heatsinking is unnecessary unless ambient exceeds 100°C or airflow is restricted in sealed enclosures.
How does the D-FLAT package affect PCB layout versus SMA/SMB?
The D-FLAT package (4.60 × 2.80 mm) offers 30% smaller footprint and 40% lower height than SMA (4.8 × 3.6 mm, 2.3 mm height), enabling tighter spacing and improved thermal coupling to inner-layer copper. Its flat bottom and exposed cathode pad enhance solder joint reliability and reduce thermal impedance compared to molded-body packages with recessed terminals.
