Product details
Overview
PDS5100-13 from Diodes Incorporated is a 5A, 100V high-voltage Schottky barrier rectifier in POWERDI®5 package, featuring 0.74V forward voltage at 5A/25°C, 120A non-repetitive surge capability, and AEC-Q101 qualification for automotive power conversion.
For engineers reviewing the PDS5100-13 datasheet, PDS5100-13 pinout, PDS5100-13 application, or PDS5100-13 equivalent, key selection criteria include low VF at high temperature, thermal resistance of 2.6°C/W (junction-to-solder point), RoHS/Green compliance, and guard ring die construction for transient robustness in DC-DC output stages.
Technical Context
This Schottky rectifier uses guard ring die construction to suppress edge breakdown and improve transient immunity. Its low forward voltage drop (0.60–0.64V at 5A/125°C) reduces conduction loss in high-efficiency 12V/24V automotive DC-DC converters.
Thermal performance is defined by three RθJA values (90/70/50°C/W) depending on PCB material and pad layout-critical for thermal design on FR-4 vs. polyimide substrates with specified cathode/anode copper areas.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage; defines safe blocking capability in 48V nominal systems. |
| IO | 5 A - Average rectified current; supports continuous output in 60W–75W SMPS designs. |
| VF @ 5A/25°C | 0.74 V - Low conduction loss enabling >92% efficiency in buck-derived outputs. |
| IFSM | 120 A - Peak surge rating for cold-start and load-dump transient handling. |
| RθJS | 2.6 °C/W - Junction-to-solder-point thermal resistance; enables direct thermal modeling to PCB copper mass. |
| IR @ 100V/125°C | 2–5 mA - Reverse leakage upper bound at max operating temperature; impacts standby power in always-on modules. |
| TJ Range | −65 to +150 °C - Extended junction temperature range supports under-hood automotive placement. |
Pinout & Package
POWERDI®5 is a surface-mount, 2-terminal plastic package with exposed cathode pad for thermal dissipation. Dimensions: 3.966 mm × 6.504 mm × 1.10 mm (L × W × A), weight ≈ 0.093 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current terminal | Connected to switching node (e.g., buck converter high-side FET drain); requires 2.7 mm × 1.6 mm copper pad per spec. |
| Cathode | Output current terminal | Connected to output filter capacitor; large 9.4 mm × 7.2 mm copper area required for RθJS = 2.6°C/W performance. |
Key Features

|---|---|
Use Scenario: Secondary-side rectification in synchronous-buck-derived 12V/24V automotive DC-DC modules powering infotainment and body control units. IC Role / Device Role / Timing Role: High-current Schottky rectifier replacing MOSFET synchronous rectifiers where gate drive complexity must be avoided. Use Value: 0.74V VF at 25°C and 0.60V at 125°C reduces conduction loss by ~35% versus standard silicon diodes, lowering thermal load on compact PCBs. | Use Scenario: Output rectification in industrial DIN-rail 24V/5A switch-mode power supplies used in PLC I/O modules and sensor interfaces. IC Role / Device Role / Timing Role: Primary freewheeling diode in non-isolated buck converters requiring high surge tolerance and long-term reliability. Use Value: 120A IFSM rating withstands repeated inrush events during hot-plug operation; AEC-Q101 qualification adds margin for extended field life. |
| LED Driver Secondary Side | Telecom 48V Intermediate Bus Converter |
Use Scenario: Output rectification in constant-current LED drivers for commercial lighting, operating at ambient up to 85°C. IC Role / Device Role / Timing Role: Low-loss freewheeling path during PWM dimming cycles; handles peak currents exceeding average rating. Use Value: Low IR (≤0.015 mA at 25°C) minimizes standby power loss in always-on drivers; green compound meets IEC 61000-6-3 EMC requirements. | Use Scenario: Output rectification in telecom intermediate bus converters stepping 48V down to 12V/5V for server rack power distribution. IC Role / Device Role / Timing Role: High-efficiency secondary-side rectifier in high-density, air-cooled power modules. Use Value: RθJS = 2.6°C/W enables direct thermal coupling to heatsink pads; 100V VRRM provides 2× safety margin over 48V nominal bus. |
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 |
|---|---|---|---|
| SB5100-E3/54 (Vishay) | Same 100V/5A rating but TO-277 package; RθJA ≈ 65°C/W (FR-4); no AEC-Q101 qualification. | Used in cost-sensitive industrial supplies; lacks automotive qualification and lower thermal performance. | Select when AEC-Q101 is not required and board space allows larger TO-277 footprint. |
| SS5P10 (ON Semiconductor) | POWERDI5 package, 100V/5A, VF = 0.75V @ 5A/25°C, but only qualified to JESD22-A108, not AEC-Q101. | Common in consumer power adapters; missing automotive stress test validation. | Choose for non-automotive applications where qualification documentation is less stringent. |
Compared with SB5100-E3/54 and SS5P10, PDS5100-13 uniquely combines AEC-Q101 qualification, 2.6°C/W RθJS, and guard ring die in the compact POWERDI®5 footprint-making it the only option qualified for under-hood automotive rectification with verified thermal and transient robustness.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The PDS5100-13 has a rated operating junction temperature range of −65°C to +150°C. For continuous operation, the absolute maximum TJ is +150°C; derating curves in Figure 6 show that at 5A average forward current, ambient temperature must be limited to ≤75°C on FR-4 PCBs to maintain safe junction temperatures.
Is the POWERDI®5 package lead-free and RoHS compliant?
Yes, PDS5100-13 features a matte tin annealed finish over copper leadframe and is fully RoHS compliant per EU Directive 2011/65/EU (RoHS 2), with all applicable exemptions applied. It is also halogen- and antimony-free, meeting Diodes Incorporated's "Green" definition (<900 ppm Br/Cl, <1000 ppm Sb).
How does the guard ring die construction improve reliability?
The guard ring structure surrounds the active junction to distribute electric field stress and prevent premature edge breakdown during high dv/dt transients. This significantly improves robustness against load-dump spikes (ISO 7637-2 Pulse 5a) and enhances long-term reliability in automotive power rails without requiring external TVS clamping.
Can PDS5100-13 replace a standard silicon rectifier in an existing design?
Yes, but thermal and electrical validation is required: its lower VF reduces conduction loss, but higher reverse leakage (up to 5 mA at 125°C) may increase standby power. Also, the POWERDI®5 footprint differs from DO-214AC or TO-277; PCB layout must match the 3.97 mm × 6.50 mm outline and specified pad dimensions for optimal thermal performance.
