Product details
Overview
DSR6V600D1-13 from Diodes Incorporated is a 600V, 6A ultra-fast recovery surface-mount rectifier in DPAK (TO-252-3L) package, featuring trr ≤ 23ns, soft recovery for low EMI, and 60A non-repetitive surge capability. It serves as the boost diode in active PFC stages of AC/DC power supplies for industrial SMPS and LED drivers.
For engineers reviewing the DSR6V600D1-13 datasheet, DSR6V600D1-13 pinout, DSR6V600D1-13 application, or DSR6V600D1-13 equivalent, key selection criteria include reverse recovery time, softness factor (S = 0.3), thermal resistance (RθJC = 10°C/W), and high-temperature stability up to +175°C junction temperature.
Technical Context
This device employs Diodes Inc.'s proprietary DIODESTAR™ process optimized for high-voltage rectification. Its ultra-fast trr (19–23 ns typ.) and soft recovery waveform minimize switching losses and EMI generation during turn-off in high-frequency PFC circuits operating at 65–135 kHz.
The 600V VRRM rating supports universal-input (85–265VAC) PFC front-ends, while its 10°C/W RθJC enables efficient heat transfer to PCB copper when mounted on double-sided 2 oz copper pads - critical for maintaining TJ ≤ 150°C under 6A continuous conduction mode operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands peak line voltage in universal-input PFC designs without breakdown |
| IO | 6 A - Continuous average forward current rating at TA = 25°C with proper PCB heatsinking |
| trr | 19–23 ns - Enables high-frequency (>100 kHz) PFC operation with minimal switching loss |
| S (Softness Factor) | 0.3 - Low di/dt during reverse recovery reduces EMI and voltage overshoot across snubbers |
| RθJC | 10 °C/W - Allows direct thermal path to copper pour; supports >4W dissipation at ΔTJC = 40°C |
| IFSM | 60 A - Handles inrush surges during cold-start of 500W+ power supplies without degradation |
| VF | 3.0 V max @ 6A - Contributes to ~18W conduction loss at full load; requires thermal design margin |
Pinout & Package
Package: DPAK (TO-252-3L), surface-mount, single-die rectifier with exposed cathode tab for thermal and electrical connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | AC input node | Connects to PFC inductor output; carries full AC-line-synchronized current |
| 2 (Cathode) | DC bus node | Exposed metal tab - electrically and thermally connects to +VOUT rail and PCB ground plane |
| 3 (Cathode) | DC bus node | Second cathode terminal; paralleled with Pin 2 to reduce trace inductance and improve thermal spreading |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast reverse recovery | trr ≤ 23 ns ensures minimal dead-time loss and reduced gate-drive stress on PFC MOSFETs |
| Soft recovery characteristic | S = 0.3 suppresses high-frequency ringing and simplifies EMI filter design |
| High-temperature stability | Operates continuously at TJ = 175°C - maintains reliability in sealed, convection-limited enclosures |
| Lead-free & RoHS-compliant | Matte tin over copper leadframe meets IPC-J-STD-020 Level 1 moisture sensitivity for standard SMT reflow |
Applications
| Industrial Switch-Mode Power Supplies | LED Driver Front-Ends |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH606D | 600V/6A, trr = 35 ns (max), RθJC = 12°C/W, TO-220AC package | Through-hole mounting; higher trr increases switching loss in >80 kHz designs | Prefer for legacy through-hole boards or lower-frequency (<65 kHz) PFC where thermal mass compensates for slower recovery |
| MBR660CT | 60V/6A Schottky, VF ≈ 0.75 V, no reverse recovery, but VRRM too low for PFC | Not rated for 600V line transients; unsuitable for universal-input PFC | Only viable in low-voltage DC/DC secondary-side rectification - not a functional substitute for DSR6V600D1-13 |
Compared with STTH606D and MBR660CT, DSR6V600D1-13 uniquely combines 600V rating, sub-25ns trr, DPAK thermal performance, and soft recovery - making it the only drop-in SMT solution for high-efficiency, high-density CCM PFC stages.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The DSR6V600D1-13 is rated for continuous operation up to TJ = +175°C. This is validated per the Absolute Maximum Ratings table and confirmed by derating curves showing usable current down to 0A at 175°C ambient when RθJA = 47°C/W. Thermal design must ensure actual TJ stays within this limit under worst-case load and airflow conditions.
Is the DPAK package's exposed cathode electrically isolated?
No - the exposed metal tab (Pins 2 and 3) is internally connected to the cathode. It serves as both the primary electrical return path and thermal interface. PCB layout must treat this area as a high-current, high-voltage node tied directly to the +VOUT rail and thermal plane, with no isolation gaps underneath.
Does the softness factor (S = 0.3) require external snubbing?
Not typically - the soft recovery waveform inherently limits di/dt during turn-off, reducing voltage overshoot. In well-layout CCM PFC designs with <5 nH stray inductance, no RC snubber is needed. However, if board layout introduces >10 nH source inductance or the system operates near 135 kHz, a small 10 Ω / 100 pF RC network across anode-cathode may further suppress ringing.
Can DSR6V600D1-13 replace older DSR6V600 in existing designs?
Yes - DSR6V600D1-13 is a direct replacement for DSR6V600 (same die, same DPAK package, same marking). The "D1" suffix denotes revision-level improvements in wafer processing yield and consistency, with identical electrical specs, thermal behavior, and footprint. No layout or firmware changes are required.
