Product details
Overview
PDS3100-13 from Diodes Incorporated is a 3A, 100V high-voltage Schottky barrier rectifier in PowerDI5 package, featuring 0.71V forward voltage at 3A/25°C, 90A non-repetitive surge capability, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in DC/DC converters and auxiliary power supplies where low conduction loss and fast switching are critical.
For engineers reviewing the PDS3100-13 datasheet, PDS3100-13 pinout, PDS3100-13 application, or PDS3100-13 equivalent, key selection criteria include forward voltage at elevated temperature, thermal resistance to solder point (6.0°C/W), reverse leakage at 125°C (≤20mA), and compatibility with FR-4 or polyimide PCB layouts per Diodes' recommended pad dimensions.
Technical Context
This Schottky rectifier uses guard ring die construction to suppress transient-induced avalanche failure and sustain repetitive 100V peak reverse voltage under industrial and automotive operating conditions. Its low VF drift across temperature (0.57–0.61V at 3A/125°C) enables stable efficiency in thermally constrained environments.
The device achieves high surge robustness (90A IFSM) via optimized metal-semiconductor junction design and thermal path engineering-junction-to-solder-point RθJS of 6.0°C/W supports direct PCB heat sinking through cathode pad (9.4mm × 7.2mm) and anode pad (2.7mm × 1.6mm).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Sustains 100V peak reverse voltage without breakdown; suitable for 48V bus-derived supplies with margin. |
| IF(AV) | 3 A - Continuous average forward current rating at TA = +25°C with specified PCB layout. |
| VF @ 3A, 25°C | 0.71 V - Low conduction loss reduces power dissipation by ~2.1W vs. silicon diode alternatives. |
| IFSM | 90 A - Withstands 8.3ms half-sine surge; supports inrush current handling in offline SMPS inputs. |
| RθJS | 6.0 °C/W - Enables direct thermal coupling to PCB copper; allows >2.5W continuous dissipation with 15°C rise above solder point. |
| IR @ 100V, 125°C | 20 mA - Reverse leakage remains bounded for stable blocking in high-temp environments like engine control units. |
| TJ Range | −65°C to +150°C - Fully rated operation across automotive under-hood and industrial ambient extremes. |

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 |
|---|---|---|---|
| Vishay VS-3EYH01-M3/54 | Same 100V VRRM, 3A IF(AV), but VF = 0.75V @ 3A/25°C; RθJA = 75°C/W on FR-4 (vs. 95°C/W for PDS3100). | Higher VF increases conduction loss by ~0.12W; less effective thermal coupling limits power density. | Select when legacy footprint compatibility is required and thermal margin exceeds 10°C. |
| ON Semiconductor SB3100 | Identical electrical specs but packaged in DO-214AA (SMB); no AEC-Q101 qualification; RθJA = 110°C/W on FR-4. | Larger footprint and higher thermal resistance preclude use in space-constrained automotive modules. | Choose only for cost-sensitive industrial prototypes where automotive qualification is not mandated. |
Compared with VS-3EYH01-M3/54 and SB3100, PDS3100-13 delivers superior thermal performance (RθJS = 6.0°C/W), guaranteed automotive reliability (AEC-Q101), and lower VF across temperature-making it optimal for high-density, mission-critical power conversion.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The PDS3100-13 is rated for continuous operation up to +150°C junction temperature. This limit is validated per AEC-Q101 stress testing and supported by its thermal resistance profile-RθJS of 6.0°C/W allows safe operation with ≤15°C rise above solder point temperature under 3A load.
Does PDS3100-13 require a heatsink on standard FR-4 PCB?
No external heatsink is required when using Diodes' recommended pad layout: cathode pad 9.4mm × 7.2mm and anode pad 2.7mm × 1.6mm on 2oz copper. The 6.0°C/W RθJS enables full 3A current handling with ≤2.5W dissipation and <15°C temperature rise above solder point.
How does the guard ring construction improve reliability?
The guard ring die structure confines electric field distribution at the semiconductor edge, preventing premature avalanche breakdown during voltage transients. This extends device lifetime in automotive and industrial environments with load dump or inductive switching noise-verified by AEC-Q101 transient overload testing.
Is PDS3100-13 compatible with lead-free reflow processes?
Yes-PDS3100-13 features matte tin annealed terminals qualified for standard lead-free reflow profiles (peak 260°C, 10s dwell). Its PowerDI5 package meets J-STD-020 moisture sensitivity level 1, eliminating bake requirements prior to assembly.
