Product details
Overview
PDS5100HQ-13D from Diodes Incorporated is a 100 V, 5 A automotive-grade Schottky barrier rectifier in PowerDI5 package, featuring 0.71 V max forward voltage at 5 A and 3.5 µA max reverse leakage at 100 V/25°C, qualified to AEC-Q101 and used for polarity protection and recirculating diode functions in engine control units and body electronics.
For engineers reviewing the PDS5100HQ-13D datasheet, PDS5100HQ-13D pinout, PDS5100HQ-13D application, or PDS5100HQ-13D equivalent, key selection criteria include its 250 A non-repetitive surge rating, 175°C maximum junction temperature, thermal resistance of 5°C/W (junction-to-case), RoHS-compliant matte tin finish, and PowerDI5 footprint compatibility with high-power density PCB layouts.
Technical Context
This Schottky rectifier employs guard ring die construction to suppress transient-induced failure and uses highly stable oxide-passivated junctions to maintain low leakage across temperature. Its low VF and high IF capability support efficient DC-DC conversion and flyback energy recovery in 12 V/24 V automotive systems.
Thermal performance is optimized via direct copper leadframe heat sinking through the bottom-side thermal pad, enabling RθJS = 2.0°C/W when soldered to a 2 oz. copper polymide PCB. The device operates reliably from –65°C to +175°C, meeting under-hood thermal demands without derating below 100°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (V) | 100 V peak repetitive reverse voltage - supports 12 V/24 V automotive bus with 3× safety margin against load dump transients |
| IF (A) | 5 A average rectified output current - sustains continuous conduction in high-duty-cycle recirculation paths |
| VF MAX (V) | 0.71 V @ 5 A, 25°C - reduces conduction loss by >30% vs. standard PN rectifiers, lowering thermal stress |
| IR MAX (µA) | 3.5 µA @ 100 V, 25°C - ensures minimal standby power loss in always-on vehicle modules |
| IFSM (A) | 250 A @ 8.3 ms half-sine - withstands motor stall and solenoid turn-off surges without degradation |
| TJ (°C) | –65 to +175°C operating range - enables placement near high-temperature sources like powertrain ECUs |
| RθJC (°C/W) | 5°C/W junction-to-case - allows direct thermal coupling to heatsink or copper pour for compact thermal design |
Pinout & Package
Package: PowerDI5 - surface-mount, thermally enhanced plastic case with exposed copper thermal pad on bottom side; UL 94V-0 rated, moisture sensitivity level 1, weight 0.096 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Left Pin | Anode | Primary current entry point; electrically connected to PCB anode trace and thermal pad for low-inductance, low-resistance path |
| Right Pin | Cathode | Current exit node; bonded directly to large cathode pad (9.4 mm × 7.2 mm) for optimal heat spreading |
| Bottom Side | Thermal Pad / Cathode Extension | Integral copper heat sink surface - must be soldered to PCB copper pour to achieve RθJS = 2.0°C/W |

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-277 package; higher RθJA (100°C/W), no AEC-Q101 qualification | Limited to industrial/commercial use; unsuitable for automotive PPAP or under-hood mounting | Select only for non-automotive cost-sensitive designs where thermal budget permits larger footprint |
| SS5P10 (ON Semiconductor) | PowerDI5 package, AEC-Q101 qualified, but VF = 0.75 V @ 5 A and IR = 5 µA @ 100 V/25°C | Slightly higher conduction loss and leakage; acceptable for less thermally constrained BCM applications | Choose when legacy SS5P10 BOM reuse is required and 0.04 V VF penalty is acceptable |
Compared with SB5100-E3/54 and SS5P10, PDS5100HQ-13D delivers superior thermal performance (RθJS = 2.0°C/W), tighter leakage control (3.5 µA), and full PPAP documentation-making it the preferred choice for AEC-Q101-compliant, space-constrained automotive power stages.

FAQ
What is the difference between PDS5100HQ-13D and PDS5100H-13D?
The PDS5100HQ-13D is the automotive-compliant variant with full AEC-Q101 qualification and PPAP capability, while PDS5100H-13D is the industrial-grade version with identical electrical specs but no automotive certification or documentation package. Both share the same PowerDI5 package, 100 V/5 A rating, and thermal characteristics.
Can PDS5100HQ-13D be used in a 48 V mild-hybrid system?
No - its 100 V VRRM rating provides insufficient margin against 48 V system transients (which can exceed 80 V during load dump). For 48 V applications, Diodes recommends the PDS5150HQ-13D (150 V rating) or equivalent higher-voltage Schottky rectifier to ensure ≥2× transient safety margin.
Is the thermal pad on the bottom side electrically isolated?
No - the bottom-side thermal pad is electrically connected to the cathode terminal. It must be routed to the cathode net on the PCB and cannot be grounded or floated. This design enables simultaneous thermal and electrical conduction, reducing parasitic inductance and improving surge handling.
Does PDS5100HQ-13D require derating at elevated ambient temperatures?
Yes - per Figure 6 in DS30471, average current must be linearly derated above 100°C ambient. At 125°C ambient, IO is reduced to ~3.8 A; at 150°C, it drops to ~2.3 A. Derating is based on RθJA = 45°C/W (polymide PCB, optimized layout), not the junction-to-case value.
