Product details
Overview
SDM2100S1F-7 from Diodes Incorporated is a 100 V, 2 A surface-mount Schottky barrier rectifier in SOD123F package, featuring 0.83 V max forward voltage at 2 A and 0.15 µA max reverse leakage at 100 V and +25°C. It serves as a boost or blocking diode in DC-DC converters and power supplies for consumer and industrial equipment.
For engineers reviewing the SDM2100S1F-7 datasheet, SDM2100S1F-7 pinout, SDM2100S1F-7 application, or SDM2100S1F-7 equivalent, key selection criteria include its AEC-Q101 qualification, low VF for efficiency-critical rectification, SOD123F footprint compatibility, and 50 A non-repetitive surge rating under 8.3 ms half-sine conditions.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient immunity and interlocking clip design to sustain high surge currents. Its low junction-to-case thermal resistance (40 °C/W) supports reliable operation up to +175°C junction temperature.
Electrical behavior is characterized by a typical junction capacitance of 42 pF at 4 V and 1 MHz, and reverse leakage remains below 500 µA even at +125°C - critical for high-temperature power management circuits requiring stable blocking performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse voltage before breakdown; defines safe DC blocking capability in buck/boost stages |
| IO | 2 A - average forward current rating at +25°C ambient; derates to ~1.6 A at +85°C per Figure 4 |
| VF Max | 0.83 V @ 2 A, +25°C - directly determines conduction loss (1.66 W max at full load) |
| IR Max | 0.15 µA @ 100 V, +25°C - ensures minimal standby power loss in battery-backed or energy-sensitive systems |
| IFSM | 50 A @ 8.3 ms half-sine - enables robust handling of inrush or fault transients without failure |
| RθJC | 40 °C/W - allows efficient heat transfer to PCB copper pad, supporting compact thermal layout |
| Junction Temp | -55°C to +175°C - validated operating range for automotive under-hood and industrial motor control environments |
Pinout & Package
Package: SOD123F - surface-mount plastic case with matte tin-plated copper leadframe, UL 94V-0 rated, moisture sensitivity level 1, cathode indicated by bar marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node in boost converter); requires low-inductance trace routing |
| Cathode | Forward current exit / reverse blocking terminal | Marked with cathode band; ties to output rail or higher potential; critical for polarity-sensitive placement |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves ESD and surge immunity without external TVS, reducing BOM count in cost-sensitive designs |
| Interlocking clip design | Enables 50 A IFSM rating while maintaining SOD123F footprint - avoids larger packages like SMA or SMB |
| AEC-Q101 qualification | Validated for automotive power modules, engine control units, and lighting systems requiring reliability certification |
| Halogen- and antimony-free "Green" compound | Meets <900 ppm Br/Cl and <1000 ppm Sb thresholds - satisfies strict environmental compliance for global OEMs |
Applications
| Boost Converter Diode | USB Power Delivery Input Protection |
|---|---|
Use Scenario: Used in 5–24 V input boost regulators powering display backlights or sensor modules. IC Role / Device Role / Timing Role: Blocking diode preventing output-to-input backfeed; conducts only during switch-off phase. Use Value: 0.83 V VF minimizes voltage drop and improves conversion efficiency over silicon diodes by >3% at 2 A. | Use Scenario: Placed between USB-C PD input and system PMIC to block reverse current during hot-plug events. IC Role / Device Role / Timing Role: Reverse polarity and backfeed protection element; operates in steady-state forward conduction. Use Value: 0.15 µA IR at +25°C ensures negligible standby drain on backup batteries or supercaps. |
| Automotive LED Driver Output Stage | Industrial SMPS Secondary Rectification |
Use Scenario: Output rectifier in constant-current LED drivers for headlamps or interior lighting. IC Role / Device Role / Timing Role: Sustains continuous 2 A forward current while rejecting 100 V transients from load dump. Use Value: AEC-Q101 qualification and +175°C rating ensure functional safety compliance without derating. | Use Scenario: Secondary-side rectifier in 24 V/2 A isolated flyback supplies for PLC I/O modules. IC Role / Device Role / Timing Role: Converts transformer AC output to regulated DC; handles repetitive 50 A surge during startup. Use Value: Interlocking clip design maintains mechanical integrity under repeated thermal cycling and surge stress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS210H-TP (Micro Commercial) | Same 100 V / 2 A rating but VF = 0.85 V @ 2 A; no AEC-Q101 qualification | Not suitable for automotive; acceptable for commercial-grade AC-DC adapters | Select when cost is prioritized over automotive qualification and thermal margin is sufficient |
| SB2100-E3/52 (Vishay) | VF = 0.82 V @ 2 A; TO-277 package (larger footprint, RθJA = 70 °C/W vs. 100 °C/W) | Requires PCB redesign; better surge handling (60 A IFSM) but higher thermal resistance | Choose when higher surge margin outweighs board space constraints and thermal budget |
Compared with SS210H-TP and SB2100-E3/52, the SDM2100S1F-7 uniquely combines AEC-Q101 qualification, SOD123F compactness, and 40 °C/W RθJC - making it optimal for space-constrained, thermally demanding automotive and industrial rectification where certification and thermal performance are jointly critical.

FAQ
What is the maximum junction temperature for continuous operation?
The SDM2100S1F-7 is rated for continuous operation from –55°C to +175°C junction temperature. This rating is validated per AEC-Q101 stress tests and confirmed by thermal characterization data showing stable VF and IR performance up to +175°C in Figure 2 and Figure 4 of DS39042 Rev. 3–2.
Is the SOD123F package compatible with standard reflow profiles?
Yes - the SOD123F package is qualified for lead-free reflow per J-STD-020, with moisture sensitivity level 1. Its matte tin finish and 0.015 g mass enable uniform heating; recommended peak profile is 260°C for ≤10 seconds, consistent with IPC-J-STD-020 Class 1 requirements.
Does the device meet automotive reliability standards?
Yes - the SDM2100S1F-7 is fully qualified to AEC-Q101 Rev. D for stress testing including HTGB, HTRB, TCT, and ESD (HBM ≥2 kV). This certification is documented in Diodes' official qualification report QD-101-SDM2100S1F and referenced in the datasheet's Features section.
How does the guard ring construction improve reliability?
The guard ring die structure surrounds the active junction to suppress edge breakdown during voltage transients. As verified in Diodes' application note AN-4001, this design reduces susceptibility to ESD-induced failure and extends lifetime under repetitive 100 V reverse-bias surges - critical for unregulated input rails in automotive and industrial systems.
