Product details
Overview
US2JDF-13 from Diodes Incorporated is a 600 V, 2.0 A ultra-fast recovery surface-mount rectifier in the D-FLAT package, featuring 75 ns reverse recovery time, 1.7 V max forward voltage at 2.0 A, and 5 μA max reverse leakage at 25°C. It serves as a primary AC-DC conversion device in high-frequency switching power supplies and LED drivers where efficiency and thermal compactness are critical.
For engineers reviewing the US2JDF-13 datasheet, US2JDF-13 pinout, US2JDF-13 application, or US2JDF-13 equivalent, key selection criteria include its 600 V peak repetitive reverse voltage, ultra-fast 75 ns trr, low-profile D-FLAT footprint (<1.1 mm height), AEC-Q101 qualification, and 50 A non-repetitive surge rating for transient robustness.
Technical Context
The US2JDF-13 employs a glass-passivated silicon die optimized for fast switching in hard-commutated topologies. Its 75 ns reverse recovery time (measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A) minimizes switching losses during turn-off transitions in SMPS and inverters.
Thermally, it delivers RθJT = 22 °C/W junction-to-terminal resistance on FR-4 PCBs with specified copper pads, enabling 2.0 A average current handling up to +125°C ambient when derated per Figure 1. The D-FLAT package supports automated placement and reflow while maintaining <1.1 mm profile for space-constrained designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| IO (AV) | 2.0 A - Sustains continuous forward current under 25°C ambient with standard PCB layout |
| VF Max | 1.7 V @ 2.0 A - Limits conduction loss to ≤3.4 W at full load, critical for thermal budgeting |
| trr | 75 ns - Enables operation up to ~2 MHz switching frequencies with minimal reverse recovery loss |
| IR Max | 5 μA @ 25°C - Ensures low standby power loss in high-impedance hold-up circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| US2J-E3/5AT (Vishay) | Same VRRM (600 V), IO (2 A), but trr = 100 ns; DPAK package (higher profile, >2.3 mm) | Less suitable for ultra-thin LED drivers due to taller package; better thermal dissipation on heatsinked boards | Select if board-level heatsinking is available and 25 ns slower recovery is acceptable |
| ES2J (ON Semiconductor) | Identical VRRM, IO, VF, and trr specs; same D-FLAT package; RoHS-compliant but not AEC-Q101 qualified | Not rated for automotive temperature range; limited to industrial/commercial environments | Select for cost-sensitive non-automotive designs where AEC-Q101 is not required |
Compared with US2JDF-13, US2J-E3/5AT trades faster recovery for higher thermal mass in DPAK, while ES2J matches all electrical specs but lacks automotive qualification-making US2JDF-13 optimal where both speed and AEC-Q101 reliability are mandatory.

FAQ
What is the maximum operating temperature for US2JDF-13?
The US2JDF-13 has an operating junction temperature range of –55°C to +150°C. Its maximum ambient temperature depends on PCB layout and power dissipation: at 2.0 A DC current and 25°C ambient, junction temperature rises by approximately 44°C (2.0 A² × 1.7 V × 22 °C/W), staying within safe limits. Derating is required above 25°C per Figure 1.
Is US2JDF-13 pin-compatible with other D-FLAT rectifiers?
Yes-US2JDF-13 uses the standard 2-pin D-FLAT footprint defined by Diodes Incorporated (E = 3.95–4.60 mm, HE = 5.0–5.6 mm). It shares pad layout compatibility with functionally similar parts like ES2J and SB260, provided polarity (cathode band orientation) is maintained during placement.
Does US2JDF-13 require a heatsink in typical applications?
No external heatsink is required for US2JDF-13 in most applications. Its RθJT = 22 °C/W and low profile allow sufficient heat transfer through PCB copper pads. At 2.0 A and 25°C ambient, junction temperature remains below 100°C with recommended 0.2 in × 0.25 in copper pads (Note 9), making it suitable for compact, fanless designs.
How does the AEC-Q101 qualification impact US2JDF-13's use in industrial designs?
AEC-Q101 qualification ensures US2JDF-13 undergoes accelerated stress testing-including temperature cycling, HTRB, and ESD-for automotive-grade reliability. While not mandatory for industrial use, this certification provides extended lifetime confidence, tighter parameter distributions, and proven robustness against thermal shock and humidity-beneficial for mission-critical or long-lifecycle industrial equipment.
