Product details
Overview
SD101AW-13 from Diodes Incorporated is a Schottky barrier switching diode in SOD-123 package, rated for 60 V peak repetitive reverse voltage, 15 mA forward continuous current, and 1.0 ns reverse recovery time. It features low forward voltage drop (0.41 V @ 1 mA), negligible reverse recovery, and 2.0 pF total capacitance at 0 V - used in high-speed signal clamping and RF detector circuits.
For engineers reviewing the SD101AW-13 datasheet, SD101AW-13 pinout, SD101AW-13 application, or SD101AW-13 equivalent, key selection criteria include its ultrafast switching performance, low capacitance for RF coupling integrity, cathode-banded polarity marking, and RoHS-compliant green molding compound.
Technical Context
This Schottky diode leverages guard ring construction to enhance transient immunity and suppress leakage-induced noise in sensitive analog front-ends. Its metal-semiconductor junction enables near-zero minority carrier storage, eliminating reverse recovery tail current.
Designed for low-current, high-frequency operation, it operates reliably from –65 °C to +125 °C with thermal resistance of 300 °C/W on FR-4 board. The 0.01 g mass and SOD-123 footprint support compact portable and wireless receiver designs.
Key Specifications

|---|---|
| VRRM | 60 V - maximum non-repetitive reverse blocking capability without breakdown |
| IF | 15 mA - continuous forward current rating under standard PCB thermal conditions |
| VFM | 0.41 V @ 1 mA - low conduction loss enabling efficient signal rectification in battery-powered detectors |
| trr | 1.0 ns - enables operation beyond 300 MHz in envelope detection and sampling applications |
| CT | 2.0 pF @ 0 V - minimal capacitive loading on RF input paths, preserving impedance matching |
| RθJA | 300 °C/W - thermal limit defines safe power derating above 25 °C ambient |

Applications
| AM/FM Radio Detector | USB Port ESD Clamp |
|---|---|
Use Scenario: Demodulating weak AM broadcast signals in portable receivers with single-diode envelope detection. IC Role / Device Role / Timing Role: Signal rectifier converting RF carrier amplitude into baseband audio envelope. Use Value: 0.41 V VFM ensures usable output down to ~200 mV input; 2.0 pF CT avoids detuning antenna-matching networks. | Use Scenario: Protecting USB 2.0 data lines (D+/D−) against ±8 kV contact ESD per IEC 61000-4-2. IC Role / Device Role / Timing Role: Low-capacitance transient voltage clamp shunting surge current to ground. Use Value: 1.0 ns trr prevents false triggering during fast-rising ESD pulses; guard ring enhances clamping consistency. |
| RF Power Monitor | Low-Power Sensor Interface |
Use Scenario: Measuring forward/reflected power in 2.4 GHz ISM-band PA output stages via directional coupler sampling. IC Role / Device Role / Timing Role: Peak voltage sampler feeding ADC input with minimal distortion. Use Value: Sub-1 ns trr preserves pulse fidelity across 20–500 MHz bandwidth; low VFM improves measurement linearity at low power levels. | Use Scenario: Level-shifting and signal conditioning for thermistor or photodiode outputs in wearable health monitors. IC Role / Device Role / Timing Role: Precision DC-coupled signal path protector and bias isolation element. Use Value: 200 nA max IRM at 50 V ensures <0.1% measurement error in μA-range sensor currents. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAT54W-7-F | VRRM = 30 V, VFM = 0.33 V @ 10 mA, CT = 10 pF @ 0 V | Higher capacitance limits use above 100 MHz; lower VRRM restricts high-voltage detector use | Select when ultra-low VFM dominates over RF bandwidth and voltage headroom |
| NSR0230P2T5G | VRRM = 30 V, VFM = 0.32 V @ 200 mA, trr = 4 ns | Slower recovery and higher current rating suit power rail OR-ing, not RF detection | Prefer for 3.3 V system-level clamping where speed is secondary to surge handling |
Compared with BAT54W-7-F and NSR0230P2T5G, SD101AW-13 uniquely balances 60 V blocking, sub-nanosecond speed, and 2 pF capacitance - making it optimal for broadband RF signal path protection and demodulation where both voltage margin and frequency response are critical.

FAQ
What is the maximum reverse voltage SD101AW-13 can block continuously?
SD101AW-13 has a peak repetitive reverse voltage (VRRM) rating of 60 V. This is the maximum instantaneous reverse voltage it can withstand repeatedly without breakdown at TA = 25 °C. Derating applies above 25 °C per the power derating curve in DS11012.
Does SD101AW-13 have a specified junction-to-case thermal resistance?
No - the datasheet specifies only junction-to-ambient thermal resistance (RθJA = 300 °C/W) under defined FR-4 board conditions. Junction-to-case (RθJC) is not published, as SOD-123's plastic package lacks a dedicated thermal pad for direct case measurement.
Is SD101AW-13 suitable for use in 5 V logic-level clamping?
Yes - with VRRM = 60 V and VFM = 0.41 V @ 1 mA, it safely clamps 5 V signals while adding negligible forward drop. Its 2.0 pF capacitance avoids signal degradation on lines operating up to several hundred MHz.
How is polarity identified on SD101AW-13?
Polarity is marked by a molded cathode band on the SOD-123 package body. The banded end is the cathode; the opposite end is the anode. This matches industry-standard SOD-123 orientation and is confirmed in the mechanical drawings on page 3 of DS11012.
