Product details
Overview
PDU620CT from Diodes Incorporated is a 6A dual ultra-fast recovery rectifier in PowerDI5 package, featuring 200V peak repetitive reverse voltage, 1.2V max forward voltage at 6A/25°C, 25ns max reverse recovery time, and 90A non-repetitive surge current. It serves as a high-efficiency freewheeling and polarity protection diode in high-frequency inverters and DC-DC converters.
For engineers reviewing the PDU620CT datasheet, PDU620CT pinout, PDU620CT application, or PDU620CT equivalent, this device is selected for high-switching-speed power conversion where low conduction loss, fast turn-off, and thermal robustness on FR-4 or polyimide PCBs are critical design requirements.
Technical Context
The PDU620CT integrates two independent ultra-fast recovery rectifier elements in a single PowerDI5 thermally optimized package. Each element delivers 3A average output current with 200V blocking capability and exhibits 25ns reverse recovery time under IF = 0.5A / IR = 1.0A test conditions.
Its glass-passivated die construction ensures stable leakage performance (5µA max at 200V/25°C), while the low RθJS of 3.0°C/W enables efficient heat transfer to the PCB soldering point-critical for sustained operation up to +150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Sustains 200V reverse bias without breakdown, suitable for 141V RMS AC line inputs or 200V DC bus applications. |
| IO (per element) | 3 A - Supports 3A continuous DC forward current per diode leg, enabling 6A total device output in dual-configuration designs. |
| tRR | 25 ns - Enables operation at >1 MHz switching frequencies with minimal switching loss and reduced EMI generation. |
| VF Max | 1.20 V @ 6A/25°C - Limits conduction loss to ≤7.2W per element at full load, easing thermal management on standard PCB layouts. |
| IFSM | 90 A - Withstands short-duration inrush or fault currents common in motor drives and SMPS startup sequences. |
| IR Max | 5 µA @ 200V/25°C - Ensures minimal standby power loss in battery-backed or energy-sensitive systems. |
| RθJS | 3.0 °C/W - Delivers predictable junction-to-solder-point thermal path, supporting accurate thermal modeling without heatsinks. |

Applications
| High-Frequency Inverters | Freewheeling Diodes in SMPS |
|---|---|
|
Use Scenario: Used in 20–100 kHz solar microinverters and UPS inverters to convert DC bus to AC output with minimal switching loss. IC Role / Device Role / Timing Role: Dual ultra-fast rectifier providing synchronous or asynchronous output stage commutation. Use Value: 25ns tRR and 1.2V VF reduce conduction + switching losses by ≥12% vs. standard fast recovery diodes at 50 kHz. |
Use Scenario: Placed across inductive loads (e.g., buck converter chokes) to clamp flyback voltage and recycle energy. IC Role / Device Role / Timing Role: Freewheeling path for stored inductor current during high-side switch off-time. Use Value: Low 5µA IR and 25ns tRR minimize voltage overshoot and improve regulation stability under light-load conditions. |
| Polarity Protection Circuits | DC-DC Converter Output Rectification |
|
Use Scenario: Installed in series with power input rails to block reverse polarity connection in industrial controllers and PoE-powered devices. IC Role / Device Role / Timing Role: Forward-biased blocking diode preventing damage from accidental negative supply insertion. Use Value: 200V VRRM withstands transients up to ±200V; 90A IFSM handles brief reverse-connection surges without failure. |
Use Scenario: Employed as secondary-side synchronous rectifier replacement in isolated flyback and forward converters. IC Role / Device Role / Timing Role: Dual-element output rectifier delivering 6A combined DC output with shared cathode return. Use Value: PowerDI5's 3.0°C/W RθJS allows full 6A output at +85°C ambient without derating-unachievable with SO-8 or TO-252 alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6L06S | 600V VRRM, 6A IO, TO-220AC package, 35ns tRR, higher VF (1.7V @ 6A) | Better for 400V+ DC bus systems; unsuitable for space-constrained PCBs due to through-hole footprint | Select when higher voltage margin or legacy through-hole assembly is required. |
| MBR620CT | 200V VRRM, 6A IO, TO-220AB package, Schottky architecture, 0.85V VF, no reverse recovery (tRR = N/A) | Limited to <125°C operation; higher IR (100µA @ 200V) reduces efficiency in high-temp environments | Prefer for low-VF priority in <100°C ambient applications; avoid where high-temperature leakage or reliability is critical. |
Compared with STTH6L06S and MBR620CT, the PDU620CT uniquely balances 200V rating, 25ns recovery, 150°C operation, and surface-mount thermal efficiency-making it optimal for compact, high-frequency, high-reliability industrial power supplies.

FAQ
What is the maximum junction temperature for continuous operation of the PDU620CT?
The PDU620CT supports continuous operation from –65°C to +150°C junction temperature. Its glass-passivated die and PowerDI5 package enable reliable performance at full 6A load up to +150°C, provided the PCB layout meets Diodes' recommended 2 oz. copper pad dimensions and thermal relief guidelines.
Can the PDU620CT be used in automotive applications?
The PDU620CT itself is not AEC-Q200 qualified; however, Diodes offers automotive-grade equivalents (e.g., PDU620CT-Q) with PPAP documentation, IATF 16949 manufacturing, and AEC-Q101 qualification. For non-automotive industrial use, the standard PDU620CT meets JEDEC high-reliability standards and is RoHS/halogen-free compliant.
How does the PowerDI5 package compare thermally to TO-220 or DPAK packages?
The PowerDI5 delivers 3.0°C/W junction-to-solder-point thermal resistance-significantly lower than TO-220 (≈40°C/W) and competitive with DPAK (≈4.5°C/W). Its exposed cathode pad and optimized copper pad layout allow direct PCB heat spreading, eliminating need for mechanical heatsinks in most 6A applications.
Is the PDU620CT suitable for synchronous rectification circuits?
No-the PDU620CT is a passive ultra-fast recovery rectifier, not a MOSFET-based synchronous rectifier. It lacks gate control and cannot be actively switched. However, its 25ns tRR and low VF make it a high-performance alternative to standard recovery diodes in quasi-resonant or fixed-frequency hard-switched topologies where synchronous control is not implemented.
