Product details
Overview
PD3S160Q-7 from Diodes Incorporated is a 1.0A, 60V surface-mount Schottky barrier rectifier in the POWERDI®323 package, featuring 0.64V max forward voltage at 1.0A and 0.05mA max reverse leakage at 60V. It is AEC-Q101 qualified for automotive polarity protection, recirculation, and switching applications with guard ring die construction for transient robustness.
For engineers reviewing the PD3S160Q-7 datasheet, PD3S160Q-7 pinout, PD3S160Q-7 application, or PD3S160Q-7 equivalent, key selection criteria include its 22A non-repetitive surge rating, 6°C/W junction-to-solder thermal resistance, RoHS-compliant matte tin finish, and qualification for under-hood automotive environments per AEC-Q101.
Technical Context
This Schottky rectifier employs a guard ring die structure to enhance transient voltage immunity and supports high-reliability automotive operation up to +150°C junction temperature. Its low 0.64V VF at 1.0A and 38pF capacitance at 10V enable efficient DC/DC conversion and fast switching in compact layouts.
The device operates with 60V peak repetitive reverse voltage and delivers 1.0A average forward current on FR-4 PCBs (RθJA = 173°C/W) or 125°C/W on polyimide substrates. Thermal performance is optimized via low RθJS of 6°C/W to solder point, enabling high-power-density designs without forced cooling.

Applications
| Automotive Polarity Protection | DC/DC Converter Output Rectification |
|---|---|
Use Scenario: Reverse battery connection protection in infotainment head units and body control modules. IC Role / Device Role / Timing Role: Unidirectional current gate placed between battery input and system rail. Use Value: 0.64V VF limits voltage drop to <3% at 1A, preserving 12V rail stability during cold-crank conditions. | Use Scenario: Secondary-side rectification in 5V/3.3V synchronous buck converters for ADAS camera modules. IC Role / Device Role / Timing Role: Freewheeling diode replacing MOSFET body diode to reduce switching loss. Use Value: 38pF capacitance and fast recovery minimize ringing and EMI in 2MHz+ switching topologies. |

IC Role / Device Role / Timing Role: Transient energy sink during PWM turn-off, limiting voltage spikes to ≤60V. Use Value: 22A IFSM handles 100ms motor stall surges without degradation, extending actuator lifetime. | Use Scenario: Overvoltage and reverse-current protection in USB-C power delivery input stages. IC Role / Device Role / Timing Role: Back-to-back diode configuration prevents reverse feed from downstream devices. Use Value: 0.05mA IR at 60V ensures negligible standby drain in always-on USB port controllers. |
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/1A rating but SMA package (4.5 × 2.7 mm); VF = 0.72V @ 1A | Larger footprint and higher VF increase thermal load in space-constrained automotive modules | Choose only if legacy SMA footprint compatibility is required |
| SS16HE3_A/H (Vishay) | POWERDI323 package, VF = 0.55V @ 1A, but AEC-Q101 not explicitly stated in datasheet | Lacks documented automotive qualification; unsuitable for PPAP-submission programs | Select only for non-automotive industrial use where qualification traceability is not mandated |
Compared with SB160-E3/54 and SS16HE3_A/H, PD3S160Q-7 uniquely combines AEC-Q101 compliance, 0.64V VF, and 2.5×1.9mm footprint-enabling smaller, thermally robust, and audit-ready automotive designs without trade-offs in surge or leakage performance.

FAQ
What is the maximum junction temperature for continuous operation?
The PD3S160Q-7 has an operating junction temperature range of –55°C to +150°C. For continuous 1.0A operation on standard FR-4 PCBs, derating begins above +75°C ambient per Figure 5; full-rated current is maintained up to +75°C with RθJA = 173°C/W.
Is the POWERDI323 package compatible with standard reflow profiles?
Yes-the PD3S160Q-7 is qualified for IPC/JEDEC J-STD-020 Level 1 moisture sensitivity and supports standard lead-free reflow profiles (peak 260°C, 30 seconds). Its matte tin finish ensures reliable wetting without voiding on OSP- or ENIG-finished boards.
Does this part support bidirectional current flow?
No-PD3S160Q-7 is a unidirectional Schottky rectifier. It conducts only from anode to cathode; reverse current is limited to ≤0.05mA at 60V. Bidirectional operation requires back-to-back configuration or a dedicated bidirectional device.
How does the guard ring structure improve reliability?
The guard ring die construction reduces electric field crowding at the PN junction edge, increasing breakdown voltage margin and improving immunity to ESD (≥8kV HBM) and load-dump transients. This eliminates need for external transient suppressors in many automotive clamp applications.
