Product details
Overview
PD3S160-7 from Diodes Incorporated is a 1.0A, 60V surface-mount Schottky barrier rectifier in the POWERDI®323 package, featuring ultra-low forward voltage (0.45V @ 1.0A), 22A non-repetitive surge capability, and AEC-Q101 qualification for automotive power conversion. It serves as a high-efficiency output rectifier in DC/DC converters and reverse-polarity protection circuits.
For engineers reviewing the PD3S160-7 datasheet, PD3S160-7 pinout, PD3S160-7 application, or PD3S160-7 equivalent, key selection criteria include forward voltage at rated current, thermal resistance (RθJA = 125°C/W on polyimide PCB), reverse leakage (<5 µA @ 60V), and AEC-Q101 reliability validation for under-hood automotive use.
Technical Context
This Schottky diode uses guard ring die construction to suppress transient-induced avalanche breakdown and sustain high surge currents without degradation. Its low RθJS of 6°C/W enables efficient heat transfer from junction to soldering point in space-constrained layouts.
The device operates across –65°C to +150°C with stable VF and IR performance, and exhibits 38 pF total capacitance at 10V reverse bias-critical for minimizing switching noise in high-frequency SMPS designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse voltage before breakdown; defines safe blocking range in 48V automotive systems. |
| IF(AV) | 1.0 A - Average forward current rating; supports continuous conduction mode operation in compact 5–12W DC/DC converters. |
| VF @ 1.0A | 0.45 V - Forward voltage drop at full rated current; reduces conduction loss by >30% vs. standard silicon diodes. |
| IFS M | 22 A - Non-repetitive peak surge current (8.3ms half-sine); withstands load dump transients in automotive ECUs. |
| RθJA | 125 °C/W - Thermal resistance on 2 oz. polyimide PCB; enables 1.0A operation up to +85°C ambient without heatsinking. |
| IR @ 60V | 5 µA - Reverse leakage current at max rated voltage; ensures low standby power loss in always-on modules. |
| CT @ 10V | 38 pF - Junction capacitance at 10V reverse bias; limits high-frequency ringing in >500kHz switching topologies. |
Pinout & Package
Package: POWERDI®323 - ultra-small surface-mount plastic package (2.50 × 1.90 × 0.13 mm), RoHS-compliant matte tin finish over copper leadframe, cathode band polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry terminal | Connected to lower-potential side (e.g., ground or switch node) in buck converter freewheel path. |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; ties to output rail or positive supply; blocks reverse current during off-state. |
Key Features

| Ultra-low VF (0.45V @ 1.0A) | Reduces forward conduction loss by ~0.45W at full load versus typical 0.7V silicon diodes-critical for thermal budget. |
| POWERDI®323 footprint | 0.006g weight and 2.5mm × 1.9mm area enable placement in dense, miniaturized PCB layouts (e.g., ADAS camera modules). |
| Halogen & antimony free | Meets "Green" definition (<900ppm Br, <900ppm Cl, <1000ppm Sb); compliant with global environmental regulations. |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Adapter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB160-E3/54 (Vishay) | Same 60V VRRM, but higher VF (0.72V @ 1.0A) and larger DO-214AA package (4.3 × 2.6 mm). | Larger footprint and 60% higher conduction loss limit use in ultra-thin or thermally constrained designs. | Select when legacy DO-214AA layout exists and thermal margin exceeds 15°C. |
| SS16 (ON Semiconductor) | Identical POWERDI323 package, but lower surge rating (15A IFSM) and no AEC-Q101 qualification. | Not approved for automotive under-hood use; suitable only for commercial-grade consumer power supplies. | Select for cost-sensitive non-automotive applications where AEC-Q101 is not required. |
Compared with SB160-E3/54 and SS16, PD3S160-7 uniquely combines AEC-Q101 qualification, ultra-low VF, and minimal 2.5×1.9mm footprint-making it the only choice for next-gen automotive modules requiring both reliability and miniaturization.

FAQ
What is the maximum operating temperature for PD3S160-7?
The PD3S160-7 has an operating junction temperature range of –65°C to +150°C. Its derating curve shows usable average forward current drops linearly from 1.0A at +25°C ambient to ~0.4A at +125°C ambient on a polyimide PCB, per Figure 5 in DS30899 Rev. 7–2.
Is PD3S160-7 suitable for synchronous rectification?
No-PD3S160-7 is a passive Schottky rectifier, not a synchronous rectifier IC. It functions as a unidirectional freewheeling or blocking diode. For active synchronous rectification, a dedicated gate driver + MOSFET pair or integrated SR controller (e.g., AP63205) is required.
Does PD3S160-7 require a heatsink in standard applications?
No external heatsink is required. With RθJA = 125°C/W on polyimide PCB and RθJS = 6°C/W, the junction-to-solder-point path efficiently dissipates heat. At 1.0A and 0.45V VF, power dissipation is 0.45W, resulting in <56°C junction rise above ambient-within safe limits.
How is the date code marked on PD3S160-7?
The date code appears as a two-character marking (e.g., "YM") on the top surface of the POWERDI323 package. The first character indicates year (e.g., "Y" = 2014), the second indicates month (e.g., "9" = September), per the Date Code Key in DS30899 Rev. 7–2 page 3.
