Product details
Overview
PDS3100Q-13 from Diodes Incorporated is a 100 V, 3 A automotive-grade Schottky barrier rectifier in POWERDI®5 package, featuring 0.76 V max forward voltage at 3 A and 0.1 mA max reverse leakage at 100 V/25°C. It serves as polarity protection, recirculating, or switching diode in high-reliability 12 V/24 V automotive power rails.
For engineers reviewing the PDS3100Q-13 datasheet, PDS3100Q-13 pinout, PDS3100Q-13 application, or PDS3100Q-13 equivalent, key selection criteria include AEC-Q101 qualification, low VF at high junction temperature, thermal resistance to solder point (6.0 °C/W), and high surge capability (90 A IFSM) for load-dump transient resilience.
Technical Context
This Schottky rectifier uses guard ring die construction to suppress voltage transients and ensure robust operation under automotive load-dump and cold-crank conditions. Its low forward voltage drop and low reverse leakage are maintained across –65°C to +150°C operating range, with thermal performance optimized for PCB-mounted heat sinking via cathode pad.
The device is electrically identical between standard and automotive versions, differing only in qualification and traceability; it requires minimum pad layouts on FR-4 (RθJA = 95 °C/W) or polyimide (RθJA = 50 °C/W) substrates to achieve rated current derating per Figure 6.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (V) | 100 V peak repetitive reverse voltage - supports 24 V automotive systems with ≥2× safety margin against ISO 7637-2 pulse 5a (120 V). |
| IF (A) | 3 A average forward current - delivers continuous power in compact footprint without forced air cooling when mounted per recommended pad layout. |
| VF MAX (V) | 0.76 V @ 3 A, 25°C - reduces conduction loss by ~30% vs. comparable silicon rectifiers, improving efficiency in battery-fed circuits. |
| IR MAX (mA) | 0.1 mA @ 100 V, 25°C - minimizes standby power drain in always-on vehicle modules such as body control units. |
| IFSM (A) | 90 A non-repetitive surge - withstands single half-sine 8.3 ms surges during alternator load dump events per ISO 16750-2. |
| RθJS (°C/W) | 6.0 °C/W junction-to-solder point - enables direct thermal coupling to copper pour for localized heat extraction in space-constrained ECUs. |
Pinout & Package
Package: POWERDI®5 - surface-mount, thermally enhanced plastic case with exposed cathode pad; UL 94V-0 rated, moisture sensitivity level 1, lead-free and halogen-free "Green" construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Left Pin | Anode | Primary current entry point; connected to input rail or switched node; requires minimal trace inductance for fast switching. |
| Right Pin | Cathode | Current exit and thermal path; must be soldered to ≥9.4 mm × 7.2 mm copper pad for RθJA = 50 °C/W performance. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge breakdown during voltage transients, enabling reliable operation in noisy automotive environments without external snubbers. |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and ESD testing - eliminates need for additional reliability screening in Tier-1 BOMs. |
| Low VF at elevated TJ | 0.61 V typ @ 3 A, 100°C - maintains efficiency in under-hood applications where ambient exceeds 85°C. |
| PPAP-capable manufacturing | Full production documentation and process control available - supports APQP compliance for OEM-supplier handoff. |
Applications
| Body Control Module (BCM) | Engine Control Unit (ECU) |
|---|---|
Use Scenario: Reverse-polarity protection on 12 V main supply input. IC Role / Device Role / Timing Role: Unidirectional current gate preventing damage from incorrect battery connection. Use Value: Eliminates need for fuse replacement after miswiring; withstands 90 A surge without failure per ISO 16750-2. | Use Scenario: Freewheeling diode across fuel injector coil. IC Role / Device Role / Timing Role: Recirculating path for inductive kickback during PWM switching. Use Value: 0.76 V VF limits clamp voltage to <15 V, protecting driver IC while minimizing energy loss in repeated actuation cycles. |
| Advanced Driver Assistance Systems (ADAS) Camera Module | Electric Power Steering (EPS) Control Board |
Use Scenario: Input rectification for 24 V auxiliary supply feeding image sensor and ISP. IC Role / Device Role / Timing Role: Primary DC input conditioning stage before LDO or buck converter. Use Value: 0.1 mA IR at 25°C ensures <1 µW standby dissipation - critical for always-on vision systems meeting OEM quiescent current targets. | Use Scenario: Clamping diode on motor phase leg of three-phase inverter bridge. IC Role / Device Role / Timing Role: High-speed recovery path for regenerative braking current. Use Value: Schottky architecture enables sub-10 ns reverse recovery, avoiding shoot-through risk during high-frequency PWM commutation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB3100-E3/57T (Vishay) | Same 100 V/3 A rating but TO-277 package; RθJA = 75 °C/W on FR-4; VF = 0.82 V max @ 3 A. | Larger footprint; less thermally efficient; not AEC-Q101 qualified. | Select if legacy TO-277 footprint compatibility required and automotive qualification not mandated. |
| SS310H (ON Semiconductor) | 100 V/3 A, SMA package; VF = 0.85 V max @ 3 A; IR = 0.5 mA @ 100 V; AEC-Q101 qualified. | Smaller thermal pad area; higher VF increases conduction loss by ~12% at full load. | Select for cost-sensitive non-under-hood applications where 0.85 V VF and 0.5 mA IR are acceptable. |
Compared with SB3100-E3/57T and SS310H, the PDS3100Q-13 offers superior thermal performance (6.0 °C/W RθJS), lowest VF (0.76 V), and smallest footprint among AEC-Q101-qualified 3 A Schottkys - making it optimal for space- and efficiency-constrained automotive power stages.

FAQ
What is the maximum junction temperature rating for PDS3100Q-13?
The PDS3100Q-13 has an operating junction temperature range of –65°C to +150°C, verified per AEC-Q101 stress tests. This allows deployment in under-hood locations such as transmission control modules where ambient temperatures exceed 105°C, provided PCB thermal design meets the specified pad layout for RθJA ≤ 50 °C/W.
Is PDS3100Q-13 compatible with lead-free reflow profiles?
Yes - the device features matte tin annealed over copper leadframe and is qualified for standard lead-free reflow per JEDEC J-STD-020. Peak temperature tolerance is 260°C for 10 seconds, and moisture sensitivity level is rated at Level 1, eliminating bake requirements prior to assembly.
Does PDS3100Q-13 require a heatsink for 3 A continuous operation?
No external heatsink is required. At 3 A and 25°C ambient, the device dissipates ~2.28 W (3 A × 0.76 V). With RθJA = 50 °C/W on polyimide PCB and proper cathode pad layout, junction temperature rise is ~114°C - well within the 150°C limit. Derating begins above 35°C ambient per Figure 6.
How is polarity identified on the PDS3100Q-13 package?
Polarity is marked on the top surface: a green bar indicates the cathode side. The right pin (when viewing top-side marking) is cathode; left pin is anode. Bottom-side thermal pad is electrically connected to cathode and must be soldered to matching PCB copper area for thermal and electrical integrity.
