Product details
Overview
SDM160S1FQ-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 delivers high efficiency in DC/DC boost stages and reverse-polarity protection circuits for automotive body electronics and industrial power supplies.
For engineers reviewing the SDM160S1FQ-7 datasheet, SDM160S1FQ-7 pinout, SDM160S1FQ-7 application, or SDM160S1FQ-7 equivalent, key selection criteria include its AEC-Q101 qualification, low VF at high temperature, surge rating of 50 A (8.3 ms), and SOD123F thermal resistance (RθJA = 100 °C/W on standard FR-4).
Technical Context
This Schottky diode uses guard ring die construction to suppress transient-induced avalanche failure and interlocking clip leadframe design to sustain 50 A non-repetitive forward surge current. Its low junction capacitance (48 pF at 10 V) supports high-frequency switching in flyback and boost converters.
The device operates across –55°C to +175°C with RθJC = 40 °C/W and is qualified per AEC-Q101 for automotive under-hood applications. Its cathode-band polarity marking and matte tin terminals ensure reliable automated assembly and solderability per MIL-STD-202.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - blocks up to 60 V reverse voltage without breakdown, suitable for 24 V automotive systems with load-dump transients |
| IO | 1 A - continuous average forward current rating at +25°C ambient, derated above +25°C per Figure 4 |
| VF Max | 0.53 V @ 1 A, +25°C - enables <0.53 W conduction loss at full load, reducing thermal stress in compact layouts |
| IR Max | 0.06 mA @ 60 V, +25°C - ensures minimal standby power loss in always-on battery-connected circuits |
| IFSM | 50 A @ 8.3 ms - withstands cold-crank and jump-start surges in automotive power rails |
| RθJA | 100 °C/W - requires thermal pad or copper pour for sustained 1 A operation above +70°C ambient |
| CT | 48 pF @ 10 V, 1 MHz - limits switching node ringing in >100 kHz DC/DC topologies |
Pinout & Package
Package: SOD123F - molded plastic case (UL 94V-0), 0.015 g weight, cathode band polarity marking, matte tin over copper leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |

| Anode | Forward current entry point | Connected to lower-potential side (e.g., ground or switch node) in boost/buck configurations |
| Cathode | Forward current exit / reverse blocking terminal | Marked with bar; connects to output rail in boost diodes or input rail in blocking diodes |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge avalanche during voltage transients, improving reliability in unregulated 12 V/24 V systems |
| Interlocking clip leadframe | Enables 50 A surge current handling without bond wire fusing, critical for engine control module power inputs |
| AEC-Q101 qualification | Validated for automotive under-hood use including temperature cycling, humidity bias, and mechanical shock tests |
| Halogen & antimony free | Meets <900 ppm Br/Cl and <1000 ppm Sb, satisfying EU ELV and OEM green material requirements |

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 60 V/1 A rating but SOD-123 package (not SOD123F); RθJA ≈ 120 °C/W; no AEC-Q101 qualification | Not approved for automotive under-hood use; limited to commercial-grade power supplies | Select only if AEC-Q101 is not required and board space permits larger thermal pad |
| SS16HE3_A/H (Vishay) | SOD-123 package; VF = 0.55 V @ 1 A; IR = 0.1 mA @ 60 V; AEC-Q101 qualified but higher leakage | Acceptable for blocking diodes where leakage <0.1 mA is tolerable, e.g., non-battery-critical modules | Prefer when cost is primary driver and leakage margin allows ≥0.1 mA at +125°C |
Compared with SB160-E3/54 and SS16HE3_A/H, SDM160S1FQ-7 offers superior thermal performance (RθJA = 100 °C/W vs. ≥120 °C/W), lower leakage (0.06 mA vs. ≥0.1 mA), and guaranteed AEC-Q101 compliance-making it the optimal choice for thermally constrained, safety-critical automotive power paths.

FAQ
What is the maximum operating temperature for SDM160S1FQ-7?
The SDM160S1FQ-7 has an operating junction temperature range of –55°C to +175°C, with storage temperature matching that range. At +175°C, reverse leakage rises to 3.7 mA (per datasheet Table 3), so thermal design must maintain TJ ≤150°C for long-term reliability in continuous 1 A operation.
Is SDM160S1FQ-7 compatible with lead-free reflow processes?
Yes-SDM160S1FQ-7 features matte tin finish on copper leadframe and is rated for standard lead-free reflow profiles (J-STD-020). Its SOD123F package passes MSL Level 1 moisture sensitivity testing, eliminating bake requirements prior to assembly.
Does SDM160S1FQ-7 have a specified junction-to-case thermal resistance?
Yes-RθJC is 40 °C/W (typical) when mounted on a 1-inch square 2 oz copper pad (Note 8). This value enables accurate junction temperature estimation in heatsinked or high-copper designs, unlike RθJA which assumes minimal PCB copper.
Can SDM160S1FQ-7 be used in place of a standard PN junction rectifier?
Yes-its Schottky architecture eliminates minority-carrier storage delay, enabling zero reverse recovery time and reduced EMI in switching supplies. However, its higher reverse leakage versus PN diodes means it's unsuitable for high-voltage hold-off where IR <1 µA is required.
