Product details
Overview
PDS5100Q-13D from Diodes Incorporated is a 100 V, 5 A automotive-grade Schottky barrier rectifier in POWERDI®5 package, featuring 0.79 V max forward voltage at 5 A and 0.2 mA max reverse leakage at 100 V/25°C. It serves as polarity protection, recirculating, or switching diode in engine control units, DC-DC converters, and battery management systems.
For engineers reviewing the PDS5100Q-13D datasheet, PDS5100Q-13D pinout, PDS5100Q-13D application, or PDS5100Q-13D equivalent, key selection criteria include AEC-Q101 qualification, 120 A non-repetitive surge rating, thermal resistance of 2.6 °C/W (junction-to-solder point), and low VF stability across -65°C to +150°C operating range.
Technical Context
This Schottky rectifier uses guard ring die construction for transient robustness and operates with minimal forward conduction loss across wide temperature ranges. Its low 0.74 V typical VF at 5 A/25°C and 0.60 V at 5 A/125°C enables high-efficiency power conversion in constrained thermal environments.
Rated for 100 V peak repetitive reverse voltage and qualified to AEC-Q101, it supports automotive applications requiring stable performance under load dump, cold crank, and thermal cycling conditions. Thermal resistance to solder point (2.6 °C/W) enables direct PCB heat sinking without external heatsinks in many layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Withstands up to 100 V reverse bias without breakdown, suitable for 12 V/24 V automotive bus protection. |
| IF(AV) | 5 A - Continuous average forward current rating at TA = +25°C with recommended PCB layout. |
| VF max | 0.79 V @ 5 A, 25°C - Low conduction loss reduces power dissipation and improves system efficiency. |
| IR max | 0.2 mA @ 100 V, 25°C - Minimal leakage preserves battery standby life in always-on vehicle modules. |
| IFSM | 120 A @ 8.3 ms - Handles high-energy inductive kickback during relay or solenoid switching. |
| RθJS | 2.6 °C/W - Enables efficient heat transfer from junction to solder point on FR-4 or polyimide PCBs. |
| TJ range | -55°C to +150°C - Fully rated operation across automotive under-hood and cabin temperature extremes. |
Pinout & Package
POWERDI®5 is a surface-mount, thermally enhanced plastic package with exposed cathode pad and integrated anode terminal. It features matte tin–annealed copper leadframe, UL 94V-0 molding compound, and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal | Connected to input/power source side; low-inductance copper leadframe minimizes switching ringing. |
| Cathode | Current exit terminal | Exposed metal pad on bottom surface; primary thermal path to PCB copper pour for heat dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Enhances ESD and transient immunity per ISO 16750-2, reducing need for external TVS in polarity protection circuits. |
| AEC-Q101 qualification | Validated for automotive reliability including temperature cycling, HTRB, and UHAST-no additional qualification required for Tier 1 designs. |
| Lead-free & halogen-free | Meets RoHS 2 and automotive "Green" standards (<900 ppm Br/Cl, <1000 ppm Sb), supporting end-of-life compliance. |
| Low RθJS (2.6 °C/W) | Enables 5 A continuous operation with minimal board area-no heatsink needed on 2 oz. copper FR-4 with standard pad layout. |
Applications
| Engine Control Unit (ECU) Polarity Protection | Automotive DC-DC Converter Output Rectification |
|---|---|
Use Scenario: Reverse battery connection protection in 12 V/24 V ECU power inputs. IC Role / Device Role / Timing Role: Unidirectional current blocking diode placed in series with main power rail. Use Value: Prevents damage from -14 V cold-crank transients while maintaining <0.8 V drop at full load current. | Use Scenario: Secondary-side rectification in synchronous or quasi-resonant 12 V → 5 V/3.3 V DC-DC converters. IC Role / Device Role / Timing Role: High-frequency freewheeling diode replacing MOSFET body diode in flyback or buck-derived topologies. Use Value: Reduces conduction loss by ~30% vs. standard silicon diode, improving converter efficiency by 1.2–1.8% at 5 A output. |
| Start-Stop System Battery Management | Body Control Module (BCM) Load Dump Clamping |
Use Scenario: Bidirectional energy recirculation during engine restart in 12 V start-stop systems. IC Role / Device Role / Timing Role: Freewheeling diode across starter motor coil or solenoid actuator. Use Value: Absorbs 120 A surge pulses without thermal runaway, enabling compact coil driver design. | Use Scenario: Clamp circuit for protecting microcontrollers and CAN transceivers during ISO 7637-2 pulse 5a load dump events. IC Role / Device Role / Timing Role: Low-VF clamping diode shunting excess voltage to ground rail. Use Value: Limits clamped voltage to ≤100 V with <0.2 mA leakage, minimizing stress on downstream 100 V-rated ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB5100-E3/54 (Vishay) | Same 100 V/5 A rating but TO-220AC package; RθJA ≈ 50 °C/W; no AEC-Q101 qualification. | Requires heatsink for 5 A continuous use; not approved for automotive production without requalification. | Select only for industrial/non-automotive designs where thermal mass compensates for higher RθJA. |
| SS5P10 (ON Semiconductor) | POWERDI-5 package, AEC-Q101 qualified, but VF = 0.82 V max @ 5 A - 30 mV higher than PDS5100Q-13D. | Slightly lower efficiency in high-duty-cycle applications; same footprint and mounting compatibility. | Acceptable drop-in replacement where 0.03 V VF penalty is tolerable and existing layout reuse is critical. |
Compared with SB5100-E3/54 and SS5P10, PDS5100Q-13D delivers superior thermal performance (2.6 °C/W RθJS), lowest VF among AEC-Q101 5 A Schottkys, and guaranteed automotive qualification-making it optimal for space-constrained, high-reliability ECU and BCM designs.

FAQ
Is PDS5100Q-13D suitable for synchronous rectification in DC-DC converters?
No-it is a unidirectional Schottky rectifier, not a synchronous MOSFET driver or controller. However, its low VF and fast recovery make it ideal as a freewheeling or output rectifier in non-synchronous buck, flyback, or boost converters up to ~500 kHz switching frequency.
What is the maximum PCB copper area required for 5 A continuous operation?
With 2 oz. copper FR-4 and Diodes' recommended pad layout (AP02001), the device sustains 5 A at +70°C ambient without heatsink. Minimum cathode pad: 9.4 mm × 7.2 mm; anode pad: 2.7 mm × 1.6 mm. Larger copper pours further reduce junction temperature.
Does PDS5100Q-13D have a built-in thermal shutdown function?
No-this is a passive rectifier with no internal thermal sensing or protection circuitry. Safe operation relies on proper PCB thermal design and derating per Fig. 6 (Forward Current Derating Curve); junction temperature must remain ≤+150°C.
Can PDS5100Q-13D replace a standard 1N5822 in automotive designs?
Yes-electrically compatible (100 V/5 A), but PDS5100Q-13D offers AEC-Q101 qualification, lower VF (0.79 V vs. 0.9 V), and superior surge rating (120 A vs. 80 A). Its POWERDI®5 package also provides better thermal performance than DO-201AD.
