Product details
Overview
SD101CW-13 from Diodes Incorporated is a Schottky barrier switching diode in SOD-123 package, rated for 40 V peak reverse voltage, 15 mA forward current, and 0.39 V forward voltage at 1.0 mA - optimized for low-power signal rectification and high-speed switching in portable electronics.
For engineers reviewing the SD101CW-13 datasheet, SD101CW-13 pinout, SD101CW-13 application, or SD101CW-13 equivalent, key selection criteria include its 1.0 ns reverse recovery time, 2.2 pF junction capacitance at 0 V, negligible stored charge, cathode-band polarity marking, and RoHS-compliant green molding compound.
Technical Context
This discrete Schottky diode uses guard ring construction to suppress transient-induced avalanche breakdown and enable robust ESD tolerance without external protection. Its metal-semiconductor junction delivers near-zero minority carrier storage, eliminating reverse recovery tail current.
Designed for ultra-low IF operation (down to 1 mA), it maintains stable VF across temperature (–65°C to +125°C) and exhibits <200 nA leakage at 30 V reverse bias - critical for battery-powered sensor nodes and signal clamping circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 40 V - Maximum DC blocking voltage before significant leakage onset; defines safe operating range in 3.3 V/5 V rail clamp designs |
| VF @ 1.0 mA | 0.39 V - Low conduction loss enabling >95% efficiency in 1.8 V logic-level signal steering |
| trr | 1.0 ns - Enables clean edge transitions in >100 MHz clock line steering and RF detector applications |
| CT @ 0 V | 2.2 pF - Minimal capacitive loading on high-impedance analog inputs or crystal oscillator feedback paths |
| IR @ 30 V | <200 nA - Ensures sub-μW standby power in always-on wake-up circuits and battery monitor comparators |
| PD | 400 mW - Sustains continuous 15 mA forward current on FR-4 PCB with standard pad layout per AP02001 |
Pinout & Package
SOD-123 surface-mount package: 2-terminal anode/cathode configuration, molded plastic body (UL 94V-0), cathode indicated by band, 0.01 g mass, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry node | Connected to higher-potential source (e.g., I/O pin, supply rail); must be routed with minimal trace inductance for RF switching |
| Cathode | Current exit node / polarity reference | Banded terminal; ties to lower-potential node (e.g., ground, logic low); determines unidirectional conduction path |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring construction | Suppresses localized electric field crowding, raising transient immunity beyond standard JEDEC Level 3 HBM (±8 kV) |
| Negligible reverse recovery time | Eliminates switching-induced voltage spikes and cross-talk in multi-rail mixed-signal PCBs |
| Low forward voltage (0.39 V @ 1 mA) | Reduces forward conduction loss by >40% vs. silicon PN diodes in 1.8 V logic interface clamping |
| RoHS-compliant green compound | Halogen- and antimony-free molding material meeting IPC-J-STD-020D reflow compatibility requirements |
Applications
| USB Data Line Protection | RF Detector Input Clamping |
|---|---|
Use Scenario: Protecting USB 2.0 D+/D− lines from ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Bidirectional clamping diode placed between data line and VDD/GND rails to shunt transients. Use Value: 1.0 ns trr prevents data eye distortion; 2.2 pF CT avoids signal integrity degradation at 480 Mbps. | Use Scenario: Limiting input swing to RF detector IC (e.g., LT5534) in 900 MHz ISM-band receivers. IC Role / Device Role / Timing Role: AC-coupled front-end clamp preventing detector saturation from strong out-of-band interferers. Use Value: 0.39 V VF ensures precise 0.4 V threshold clamping; low CT preserves detector bandwidth. |
| Low-Power Sensor Wake-Up Circuit | Crystal Oscillator Load Capacitance Trim |
Use Scenario: Enabling ultra-low-IQ microcontroller wake-up via external interrupt pin driven by analog sensor output. IC Role / Device Role / Timing Role: Signal-level translator isolating sensor output from MCU input while blocking reverse leakage. Use Value: <200 nA IR at 30 V ensures <100 nW standby load; SOD-123 footprint saves board space in wearables. | Use Scenario: Fine-tuning effective load capacitance in 32.768 kHz watch crystal oscillator circuits. IC Role / Device Role / Timing Role: Voltage-dependent junction capacitor used in series/parallel with crystal to adjust oscillation frequency. Use Value: 2.2 pF CT at 0 V provides predictable trim range; low VF avoids DC bias shift on crystal terminals. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54LT1G | Higher VRWM (30 V), same SOD-123, but VF = 0.33 V @ 10 mA (vs. 0.39 V @ 1 mA) | Better suited for 3.3 V rail-to-rail clamping with higher surge margin | Select when forward current exceeds 5 mA and lower VF dominates over leakage |
| BAT54C,215 | Same VRWM (30 V), dual common-cathode configuration, VF = 0.24 V @ 10 mA | Enables dual-channel clamping in single footprint; not pin-compatible for single-diode use | Choose only if dual-diode topology matches system layout and leakage budget allows |
Compared with SBAT54LT1G and BAT54C,215, SD101CW-13 offers superior low-current VF stability below 2 mA and tighter leakage control at 30 V - making it optimal for micropower sensor interfaces where sub-μA standby current is mandatory.

FAQ
Is SD101CW-13 suitable for 5 V logic-level clamping?
Yes. With a 40 V VRWM and 0.39 V VF at 1 mA, SD101CW-13 safely clamps 5 V signals to ~0.4 V above GND or ~0.4 V below VCC without forward conduction loss or thermal runaway. Its 2.2 pF capacitance avoids signal rise-time degradation in 5 V GPIO protection.
What is the maximum ambient temperature for continuous 15 mA operation?
At 25°C ambient, full 15 mA forward current is supported. Derating begins at 100°C ambient per Figure 4: power dissipation drops linearly to zero at 150°C. On standard FR-4 with recommended pads (AP02001), 15 mA is sustainable up to 125°C ambient with 400 mW derated to ~133 mW.
Does SD101CW-13 meet automotive AEC-Q200 requirements?
No. SD101CW-13 is not AEC-Q200 qualified. It operates from –65°C to +125°C and meets J-STD-020D moisture sensitivity level 1, but lacks the stress testing, lot traceability, and failure analysis reporting required for automotive qualification. Use AS3401 or DSA2040 for AEC-Q200-compliant alternatives.
Can SD101CW-13 replace SD101BW-13 in existing designs?
Yes, with design verification. SD101CW-13 has lower VRWM (40 V vs. 50 V) and slightly lower VF (0.39 V vs. 0.40 V @ 1 mA). If system reverse voltage never exceeds 40 V and leakage at 30 V remains acceptable (<200 nA), substitution is functionally valid and may improve low-current efficiency.
