Product details
Overview
DSR6U600D1-13 from Diodes Incorporated is an ultra-fast, soft-recovery 600 V, 6 A surface-mount rectifier in TO252 (DPAK) package, optimized as a boost diode in active PFC stages of AC-DC power supplies. It delivers trr < 25 ns (typ), VF = 2.1 V at 6 A, and Qrr = 220 nC, enabling high-efficiency operation with low EMI in 85–265 VAC offline converters.
For engineers reviewing the DSR6U600D1-13 datasheet, DSR6U600D1-13 pinout, DSR6U600D1-13 application, or DSR6U600D1-13 equivalent, key selection criteria include reverse recovery performance under high di/dt, thermal resistance (RθJS = 10 °C/W), surge capability (IFSM = 60 A), and softness factor (S = 0.5) for EMI-sensitive PFC designs.
Technical Context
This rectifier employs Diodes Inc.'s proprietary DIODESTAR™ process to achieve ultra-fast, soft reverse recovery-critical for minimizing switching losses and voltage overshoot in continuous conduction mode (CCM) PFC boost stages. Its low Qrr and controlled IRM reduce turn-off stress on the MOSFET switch.
The device is rated for TJ = –65°C to +175°C, with RθJA = 47 °C/W on standard PCB layout and RθJS = 10 °C/W when soldered to a 2 oz copper heatsink pad. Its 600 V VRRM supports universal-input front-end designs with margin against line transients.
Key Specifications

| Anode (Lead 1) | Input node for AC/switching node connection | Connected to PFC boost inductor output; carries full AC input current during conduction |
| Cathode (Tab / Lead 2) | Output node and thermal path | Electrically and thermally tied to DC bus (+); requires ≥1"² 2 oz copper pour for RθJS = 10 °C/W |
| NC (Lead 3) | No internal connection | Unused lead; must be left floating or grounded per layout guidelines to avoid parasitic coupling |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast soft recovery | trr ≤ 25 ns with S = 0.5 - Minimizes EMI and voltage overshoot during hard-switched PFC transitions |
| High surge robustness | IFSM = 60 A (8.3 ms half-sine) - Survives cold-start inrush and transient overloads without degradation |
| High-temperature stability | Operates continuously up to TJ = +175°C - Enables compact, fanless industrial and server PSU designs |
| Low Qrr & IRM | Qrr = 220 nC, IRM = 4.3 A - Reduces switching loss and snubber requirements in CCM boost converters |
| RoHS-compliant finish | Matte tin over copper leadframe - Ensures reliable solderability and long-term intermetallic stability |

|---|---|---|---|
| STTH6L06D | VRRM = 600 V, IO = 6 A, trr = 35 ns (max), Qrr = 320 nC | Higher Qrr increases MOSFET stress in high-frequency PFC; requires larger snubber | Acceptable where EMI is less constrained and cost sensitivity outweighs efficiency gain |
| IXYS MUR660E | VRRM = 600 V, IO = 6 A, trr = 30 ns (max), VF = 2.3 V (typ) | Higher VF increases conduction loss by ~1.2 W at 6 A; lower softness factor (S ≈ 0.35) | Suitable for lower-frequency (<75 kHz) PFC or where thermal margin exists for higher VF |

FAQ
What is the maximum recommended PCB copper area for optimal thermal performance?
The datasheet specifies RθJS = 10 °C/W when mounted on a 1" × 1", 2 oz double-sided copper PCB. For best results, use ≥1.2"² of exposed cathode pad connected via ≥4 thermal vias (0.3 mm diameter) to inner ground/power planes. Avoid solder mask over the cathode tab.
Is DSR6U600D1-13 suitable for use in automotive power supplies?
While qualified for industrial temperature range (–65°C to +175°C), DSR6U600D1-13 is not AEC-Q101 qualified and lacks automotive-specific reliability testing (e.g., HTOL, TCT). It may be used in non-safety-critical aftermarket or commercial vehicle systems, but not in ADAS or powertrain applications.
How does the softness factor (S = 0.5) impact EMI performance?
A softness factor of 0.5 indicates gradual current decay during reverse recovery, suppressing high di/dt-induced ringing. This reduces broadband EMI amplitude by 10–15 dB in the 30–100 MHz range compared to hard-recovery diodes, easing compliance with EN 55032 Class B limits.
Can DSR6U600D1-13 replace DSR6U600D1S-13 in existing designs?
Yes-DSR6U600D1-13 and DSR6U600D1S-13 share identical electrical specs, package, and pinout. The "S" suffix denotes tape-and-reel packaging with different reel marking (DSR6U600(S)), but both are functionally and mechanically interchangeable in PCB layouts and thermal designs.
