Product details
Overview
SDM160S1F-7 from Diodes Incorporated is a 60 V, 1 A surface-mount Schottky rectifier in SOD123F package, featuring 0.53 V max forward voltage at 1 A and 0.06 mA max reverse leakage at 60 V and +25°C. It serves as a boost or blocking diode in DC-DC converters and power supplies for consumer, industrial, and automotive applications.
For engineers reviewing the SDM160S1F-7 datasheet, SDM160S1F-7 pinout, SDM160S1F-7 application, or SDM160S1F-7 equivalent, key selection criteria include VF vs. IO trade-off, surge current rating (50 A IFSM), thermal resistance (RθJA = 110 °C/W on FR-4), and AEC-Q101 qualification for reliability-critical designs.
Technical Context
This Schottky rectifier uses guard ring die construction to suppress transient-induced junction breakdown and interlocking clip leadframe design to sustain high surge currents. Its low VF enables reduced conduction loss in high-frequency switching topologies.
It operates across –55°C to +175°C junction temperature range with RθJC = 40 °C/W (FR-4) and RθJS = 18 °C/W (solder point), supporting compact thermal layout in space-constrained PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse voltage before avalanche; sets safe operating limit in boost/buck output stage |
| IO | 1 A - Continuous average forward current; defines steady-state power handling in rectification path |
| VF Max | 0.53 V @ 1 A, +25°C - Low conduction loss improves efficiency in 5–24 V DC-DC stages |
| IFSM | 50 A @ 8.3 ms - Withstands inrush and short-circuit surges without bondwire failure |
| IR Max | 0.06 mA @ 60 V, +25°C - Minimizes standby power loss in always-on circuits |
| CT | 48 pF @ 10 V, 1 MHz - Low junction capacitance reduces switching loss and EMI in >100 kHz converters |
| TJ Range | –55°C to +175°C - Enables operation in under-hood automotive or industrial ambient environments |
Pinout & Package
Package: SOD123F - Surface-mount plastic case (UL 94V-0), 0.015 g weight, matte tin-plated copper leadframe, cathode band polarity marking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS12 | Same 60 V VRRM, but 1.2 A IO and higher VF (0.55 V typ @ 1 A); SOD-123 package (not SOD123F) | Slightly higher thermal resistance due to non-F variant; less suitable for high-density layouts requiring tighter pitch | Prefer SDM160S1F-7 where board space and thermal performance are constrained |
| SB160 | 60 V VRRM, 1 A IO, but TO-277 package (higher RθJA ≈ 150 °C/W); VF = 0.75 V max @ 1 A | Larger footprint and higher conduction loss reduce suitability for portable or thermally limited designs | Select SDM160S1F-7 when low-profile SMT mounting and efficiency are prioritized over legacy through-hole compatibility |
Compared with SS12 and SB160, SDM160S1F-7 delivers superior thermal performance (RθJA = 110 °C/W), lower VF (0.53 V), and AEC-Q101 qualification-making it optimal for automotive and high-efficiency compact power supplies where reliability and size matter.

FAQ
What is the maximum junction temperature for SDM160S1F-7?
The SDM160S1F-7 has a specified operating junction temperature range of –55°C to +175°C. This wide range supports use in under-hood automotive environments and high-ambient industrial settings. Thermal design must ensure TJ does not exceed +175°C under worst-case power dissipation and ambient conditions.
Is SDM160S1F-7 RoHS and halogen-free compliant?
Yes. SDM160S1F-7 meets EU RoHS Directive 2011/65/EU and is halogen- and antimony-free ("Green"), with bromine and chlorine each <900 ppm and antimony <1000 ppm. The molding compound is UL 94V-0 rated, and terminals have matte tin finish over copper leadframe.
Does SDM160S1F-7 have automotive qualification?
Yes. SDM160S1F-7 is qualified to AEC-Q101 standards for high-reliability automotive applications. An automotive-specific variant (SDM160S1FQ) is also available with identical electrical specs and enhanced traceability documentation.
What is the typical thermal resistance from junction to ambient?
RθJA is 110 °C/W when mounted on a 1×1 inch FR-4 PCB with 2 oz. copper. On a 1-inch² copper pad (2 oz.), RθJA drops to 75 °C/W. These values assume standard JEDEC test conditions and guide heatsinking decisions for continuous 1 A operation.
