Product details
Overview
SDM2100S1FQ-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 delivers high surge current capacity (50 A IFSM), low power loss, and AEC-Q101 qualification for automotive boost and blocking diode applications.
For engineers reviewing the SDM2100S1FQ-7 datasheet, SDM2100S1FQ-7 pinout, SDM2100S1FQ-7 application, or SDM2100S1FQ-7 equivalent, key selection criteria include its 100 V reverse voltage rating, thermal resistance (RθJA = 100 °C/W), junction capacitance (42 pF), AEC-Q101 qualification status, and SOD123F footprint compatibility with space-constrained DC/DC and automotive power stages.
Technical Context
This Schottky rectifier uses guard ring die construction to enhance transient voltage immunity and interlocking clip design to sustain 50 A non-repetitive surge current under 8.3 ms half-sine conditions. Its low VF (0.74–0.83 V across +25°C to +125°C) directly reduces conduction loss in high-frequency switching topologies.
Rated for operation from –55°C to +175°C, it maintains stable leakage performance (≤500 μA at +125°C/100 V) and exhibits predictable forward characteristics across temperature, enabling reliable use in under-hood automotive environments and industrial power supplies where thermal derating must be precisely modeled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; defines safe blocking capability in boost converter output stage |
| IO | 2 A - Continuous average forward current at TA = +25°C; derates to ~1.6 A at +85°C per Figure 4 |
| VF Max | 0.83 V @ 2 A, +25°C - Directly determines conduction loss (Pcond ≈ 1.66 W at full load) |
| IR Max | 0.15 μA @ 100 V, +25°C - Enables low standby power in battery-backed systems |
| IFSM | 50 A @ 8.3 ms - Supports robust startup and fault-current handling without bond wire fusing |
| CT | 42 pF @ 4 V, 1 MHz - Limits high-frequency switching noise and EMI in SMPS feedback paths |
| RθJA | 100 °C/W - Defines thermal rise on standard FR-4 PCB; requires layout optimization above 1 A continuous |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB2100-TB | Same 100 V/2 A rating but SOD-123 package (not SOD123F); RθJA = 120 °C/W; no AEC-Q101 qualification | Lacks automotive qualification and has higher thermal resistance; suitable only for commercial-grade power supplies | Select when cost is prioritized over automotive compliance and thermal performance is less constrained |
| SS210H | 100 V/2 A, SOD-123FL package, VF = 0.85 V max @ 2 A, IR = 0.2 μA max, AEC-Q101 qualified | Higher VF increases conduction loss; identical qualification and footprint compatibility | Prefer when sourcing flexibility is needed across multiple Diodes Inc. lines, accepting marginal efficiency trade-off |
Compared with SB2100-TB and SS210H, the SDM2100S1FQ-7 uniquely combines AEC-Q101 qualification, lowest VF (0.83 V), and optimized SOD123F thermal performance (RθJA = 100 °C/W), making it the preferred choice for thermally demanding automotive and industrial rectification where efficiency and reliability are co-prioritized.

FAQ
Is SDM2100S1FQ-7 suitable for synchronous rectification circuits?
No - SDM2100S1FQ-7 is a passive Schottky rectifier, not a synchronous rectifier IC or MOSFET-based device. It functions as a unidirectional current valve and cannot be actively controlled or driven by gate signals. For synchronous rectification, discrete MOSFETs or dedicated SR controllers (e.g., AP6320x) must be used instead.
What is the maximum allowable junction temperature during continuous operation?
The SDM2100S1FQ-7 has a rated maximum junction temperature of +175°C. Under continuous 2 A DC operation at +25°C ambient, junction temperature rises ~200°C (2 A² × RθJA × 100 °C/W), exceeding rating - thus derating is mandatory. At +85°C ambient, maximum sustainable IO is ~1.6 A per Figure 4 to maintain TJ ≤ +175°C.
Does the SOD123F package support automated optical inspection (AOI) after reflow?
Yes - the SOD123F package features coplanar, well-defined anode/cathode terminals and a visible cathode band marking. Its standardized dimensions (E = 2.70 mm, He = 3.50 mm) and matte tin finish enable reliable AOI detection of solder joint quality, tombstoning, and polarity orientation on high-volume SMT lines.
How does the guard ring structure improve reliability in automotive environments?
The guard ring die construction surrounds the active junction with a doped region that redistributes electric field stress during voltage transients. This suppresses edge breakdown and prevents localized hot-spot formation during load-dump events (ISO 7637-2 Pulse 5a), extending device lifetime in 12 V/24 V automotive systems without requiring additional clamping components.
