Product details
Overview
PDS4200H-13 from Diodes Incorporated is a 4A, 200V high-voltage Schottky barrier rectifier in POWERDI®5 package, designed for high-efficiency DC/DC conversion and output rectification in switch-mode power supplies. It delivers VF = 0.76 V at 3A/25°C, IR ≤ 0.2 µA at 200V/25°C, trr ≤ 25 ns, and supports IFSM = 100 A surge current - enabling compact, thermally efficient designs in automotive and industrial power adapters.
For engineers reviewing the PDS4200H-13 datasheet, PDS4200H-13 pinout, PDS4200H-13 application, or PDS4200H-13 equivalent, key selection criteria include forward voltage at elevated temperature (VF = 0.61 V @ 3A/150°C), soft recovery (tb/ta ≥ 1), thermal resistance RθJS = 3.0 °C/W, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Schottky rectifier uses an oxide-passivated metal-semiconductor junction to achieve low conduction loss and minimal reverse recovery charge. Its soft recovery behavior (tb/ta ≥ 1) reduces EMI in high-frequency switching topologies, while the 200V VRRM rating supports 12–48V input bus applications with margin.
The POWERDI®5 package integrates a thermally optimized copper leadframe with 9.4 mm × 7.2 mm cathode pad and 2.7 mm × 1.6 mm anode pad, enabling RθJA as low as 45 °C/W on polyimide PCBs - critical for sustained 4A operation without forced air cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Withstands peak reverse transients up to 200V without breakdown, suitable for 48V automotive systems with load-dump protection margin. |
| IO | 4 A - Continuous average forward current rating at TA = 25°C with minimum PCB copper; derates to ~2.5A at 100°C ambient. |
| VF @ 3A/25°C | 0.76 V - Low conduction loss enables >92% efficiency in 12V-to-5V buck converters at full load. |
| IR @ 200V/25°C | ≤0.2 µA - Ultra-low leakage preserves battery standby time in always-on automotive modules. |
| trr | ≤25 ns - Fast, soft recovery minimizes switching node ringing and EMI filter component count. |
| RθJS | 3.0 °C/W - Enables direct thermal path from junction to solder point, supporting high-power density layouts. |
| IFSM | 100 A - Handles inrush surges during hot-plug events in industrial power supplies without degradation. |
Pinout & Package
POWERDI®5 is a surface-mount, single-diode package with two terminals: Anode (pin 1) and Cathode (pin 2). The molded plastic case features matte tin–annealed copper leadframe, UL 94V-0 flammability rating, and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for forward conduction | Connected to input rail (e.g., switching node of buck converter); requires 2.7 mm × 1.6 mm copper pad for thermal and mechanical integrity. |
| Cathode | Output terminal for forward conduction | Connected to output rail (e.g., output capacitor); uses large 9.4 mm × 7.2 mm pad to dissipate heat and reduce thermal resistance to 45 °C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Soft recovery (tb/ta ≥ 1) | Reduces voltage overshoot and EMI generation during turn-off, lowering need for snubbers in 300–500 kHz SMPS designs. |
| AEC-Q101 qualified | Validated for automotive under-hood applications including engine control units and ADAS power rails. |
| Low VF at high temperature | VF = 0.61 V @ 3A/150°C ensures stable efficiency across extended thermal range without thermal runaway. |
| Oxide-passivated junction | Enhances long-term reliability under humidity and thermal cycling stress, exceeding 1000 hours HAST testing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB420-E3/57T (Vishay) | Same 200V/4A rating but VF = 0.82 V @ 3A/25°C; no AEC-Q101 qualification. | Acceptable for commercial-grade AC/DC adapters but not automotive under-hood use. | Select when cost sensitivity outweighs automotive qualification and thermal performance. |
| SS4P2L (ON Semiconductor) | Lower VRRM (200V same), but VF = 0.72 V @ 3A/25°C and RθJA = 50 °C/W (FR-4); no soft recovery data published. | Suitable for space-constrained consumer power bricks where EMI filtering is less critical. | Select when lower VF is prioritized over soft recovery and automotive compliance. |
Compared with SB420-E3/57T and SS4P2L, the PDS4200H-13 uniquely combines AEC-Q101 qualification, soft recovery (tb/ta ≥ 1), and 3.0 °C/W RθJS - making it the only choice for thermally demanding, safety-critical automotive power stages requiring both efficiency and EMI control.

FAQ
What is the maximum junction temperature for continuous operation?
The PDS4200H-13 has an operating junction temperature range of –65°C to +175°C. For continuous 4A operation, thermal design must maintain TJ ≤ 150°C using the specified 9.4 mm × 7.2 mm cathode pad on polyimide PCB to achieve RθJA = 45 °C/W. Exceeding 175°C risks permanent parametric shift and bondwire failure.
Is the PDS4200H-13 suitable for synchronous rectification?
No - the PDS4200H-13 is a passive Schottky rectifier, not a MOSFET-based synchronous rectifier controller or driver. It functions as a unidirectional, self-commutating diode and cannot be actively gated. For synchronous designs, discrete N-channel MOSFETs with gate drivers are required.
How does the soft recovery characteristic impact EMI performance?
The soft recovery (tb/ta ≥ 1) limits dI/dt during turn-off, suppressing high-frequency ringing on the switching node. Measured oscilloscope waveforms show <15% overshoot vs. >40% with ultrafast diodes at 100 kHz, directly reducing conducted EMI in Class B power supplies without added ferrite beads or RC snubbers.
What is the recommended PCB pad layout for optimal thermal performance?
Per Diodes AP02001, use a 9.4 mm × 7.2 mm thermal pad for the cathode and 2.7 mm × 1.6 mm for the anode on 2 oz. copper polyimide PCB. Include ≥4 thermal vias (0.3 mm diameter, filled) under the cathode pad connected to internal ground plane. Avoid solder mask over thermal pads to maximize heat transfer.
