Product details
Overview
PDU340-13 from Diodes Incorporated is a 3.0A glass passivated ultra-fast recovery rectifier in PowerDI5 package, rated for 400V peak repetitive reverse voltage, 1.25V max forward voltage at 3A/25°C, and 50ns reverse recovery time. It serves as a high-efficiency freewheeling diode in high-frequency inverters and polarity protection circuits in industrial power supplies.
For engineers reviewing the PDU340-13 datasheet, PDU340-13 pinout, PDU340-13 application, or PDU340-13 equivalent, key selection criteria include ultra-fast tRR (50ns), high IFSM (55A), thermal resistance to solder point (5°C/W), and PowerDI5's low-profile thermally efficient layout for PCB-level heat dissipation in compact converters.
Technical Context
This rectifier uses a glass-passivated PN junction optimized for rapid carrier recombination, enabling 50ns reverse recovery under IF = 0.5A / IR = 1.0A test conditions. Its 150°C maximum junction temperature and 55A non-repetitive surge rating support robust operation in transient-heavy switching topologies.
The PowerDI5 package features a bottom-side heatsink structure with exposed cathode pad (9.4mm × 7.2mm) and anode pad (2.7mm × 1.6mm), delivering RθJS = 5°C/W to solder point - critical for thermal management in space-constrained 100–500kHz DC/DC and inverter designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Withstands 400V peak reverse voltage without breakdown; suitable for 283V RMS input lines. |
| IO | 3 A - Continuous average forward current at TA = +25°C with recommended FR-4 PCB layout. |
| tRR | 50 ns - Ultra-fast recovery minimizes switching losses in 100–500kHz SMPS and inverters. |
| VF Max | 1.25 V @ 3A/25°C - Low conduction loss enables >92% efficiency in 12V–48V output rectification stages. |
| IFSM | 55 A - Handles single half-sine surge up to 55A (8.3ms), supporting motor drive startup and load dump events. |
| RθJS | 5 °C/W - Junction-to-solder-point thermal resistance enables direct PCB copper thermal path for high-power density layouts. |
| TJ Range | −65°C to +150°C - Wide operating range supports automotive under-hood and industrial ambient environments. |
Pinout & Package
PowerDI5 is a surface-mount, low-profile (1.15mm max height), thermally enhanced package with exposed cathode pad on bottom side. Anode and cathode terminals are accessible via left and right leads respectively; both must be electrically connected to PCB copper for optimal thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Left Pin | Anode | Forward current entry point; connects to input/high-side node in rectifier configuration. |
| Right Pin | Cathode | Forward current exit point; ties to output/low-side node and serves as primary thermal path to PCB heatsink area. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enhanced moisture and contamination resistance vs. epoxy-passivated devices; improves long-term reliability in humid industrial environments. |
| Ultra-fast tRR = 50ns | Reduces reverse recovery charge (Qrr) and associated switching losses in high-frequency (>100kHz) topologies. |
| Bottom-side heatsink | Exposed cathode pad enables direct thermal coupling to large PCB copper areas, lowering effective RθJA by up to 60% vs. standard SOD-123. |
| Lead-free & halogen-free | RoHS 2 compliant with <900ppm Br/Cl and <1000ppm Sb; meets IPC-J-STD-020 Level 1 moisture sensitivity for standard reflow. |
Applications
| High-Frequency Inverters | Freewheeling Diode |
|---|---|
Use Scenario: 200kHz solar microinverter DC/AC stage with SiC MOSFETs requiring minimal reverse recovery loss. IC Role / Device Role / Timing Role: Output rectifier handling bidirectional current during dead-time commutation. Use Value: 50ns tRR reduces turn-off loss in SiC half-bridge, improving system efficiency by ~1.2% at full load. |
Use Scenario: 48V telecom DC/DC converter using synchronous rectification, where freewheeling path must handle 3A continuous current. IC Role / Device Role / Timing Role: Freewheeling path during low-side FET off-time; clamps inductive kickback in buck regulator. Use Value: 55A IFSM withstands inrush surges during cold start; 150°C TJ rating ensures stability under sustained 85°C ambient. |
| Polarity Protection | Capacitor Charging Circuit |
Use Scenario: Input protection for 24V industrial PLC module against reverse battery connection. IC Role / Device Role / Timing Role: Series blocking diode preventing reverse current flow into sensitive downstream circuitry. Use Value: 400V VRRM provides 2× margin over 24V nominal; 1.25V VF limits power loss to <3.75W at 3A. |
Use Scenario: Controlled charging of bulk electrolytic capacitor in AC/DC front-end with soft-start requirement. IC Role / Device Role / Timing Role: Unidirectional current path limiting inrush while sustaining steady-state 3A load. Use Value: Glass passivation prevents leakage degradation under repeated voltage stress; 10μA IR at 400V ensures low standby drain. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600V VRRM, 3A IO, tRR = 35ns, TO-277 package (RθJA ≈ 75°C/W) | Higher voltage rating but higher thermal resistance; less effective PCB heat spreading than PowerDI5 | Prefer when >400V line transients are expected; avoid if board space or thermal budget is constrained. |
| ES3D-E3/57T | 200V VRRM, 3A IO, tRR = 35ns, SMA package (RθJA ≈ 90°C/W) | Lower voltage rating and inferior thermal performance; no bottom-side heatsink | Only suitable for ≤200V systems with light thermal loading; not drop-in for 400V or high-ambient designs. |
Compared with STTH3L06S and ES3D-E3/57T, PDU340-13 delivers optimal balance of 400V rating, 50ns speed, and PowerDI5's 5°C/W RθJS - making it uniquely suited for thermally dense, high-frequency 24–48V industrial power stages where both voltage margin and thermal headroom matter.

FAQ
What is the maximum allowable junction temperature for PDU340-13?
The PDU340-13 has a specified operating junction temperature range of −65°C to +150°C. This allows reliable operation in harsh environments such as industrial motor drives or outdoor telecom equipment, provided thermal design maintains TJ ≤ 150°C under worst-case load and ambient conditions.
Can PDU340-13 replace a standard FR107 in a 400V flyback design?
No - although both are 400V rectifiers, PDU340-13 has 50ns tRR versus FR107's 500ns, making it unsuitable as a direct replacement without circuit re-optimization. Faster recovery demands careful attention to snubber design and EMI filtering due to higher di/dt.
Is the PowerDI5 package lead-free and RoHS-compliant?
Yes - PDU340-13 features matte tin annealed terminals over copper leadframe and complies with EU RoHS Directive 2011/65/EU. It is also halogen- and antimony-free per Diodes' "Green" definition (<900ppm Br/Cl, <1000ppm Sb).
How does the bottom-side heatsink in PowerDI5 improve thermal performance?
The exposed cathode pad on the PowerDI5 bottom surface provides a low-resistance thermal path to PCB copper. With proper pad layout (9.4mm × 7.2mm cathode area), RθJS drops to 5°C/W - significantly lower than traditional SMD packages - enabling higher power density without external heatsinks.
